An Open Letter to President-Elect Trump

By Percy Menzies, Guest Columnist

Dear President-Elect Trump,

You will soon have an extraordinary opportunity to save thousands of lives with one stroke of the pen! I am talking about reducing overdose deaths from opioid overdoses. How is this possible?

We have three highly effective medications for the treatment of opioid addiction, but they are grossly under-utilized, largely due to accessibility. Two of the three drugs used to treat opioid use disorder have restrictions that have no place when overdose deaths exceed 30,000 per year. These restrictions made sense at a different time, but these barriers are now inadvertently contributing to overdose deaths.

I am specifically talking about buprenorphine, the most widely used medication in the battle against the opioid epidemic. This medication, better known by its brand name Suboxone, is an opioid with a very safe profile. Its unique pharmacology makes it almost impossible to overdose.

There are barriers to the use of this medication which made sense 14 years ago, when heroin was not a public health issue, but today they are a hindrance to saving lives.

Buprenorphine is the only drug that requires physicians to complete eight hours of training and then apply to the Drug Enforcement Administration to obtain a special exemption to prescribe it. It gets worse. Physicians can only treat 30 patients with this medication in the first year, and then they must obtain permission from the DEA to increase the limit to 100 patients. The physician also has to keep clear records and can expect a visit from a DEA agent to look at the records. 

This is a major deterrent and way too few physicians have bothered to obtain the required exemption. Any physician who has a DEA license can prescribe an FDA-approved controlled substance without restriction, but they have to deal with this barrier to prescribe buprenorphine. 

These restrictions were put in place to prevent buprenorphine from joining the opioid “pill mills” when few anticipated heroin sweeping our cities and towns. At the present time, there is no strategy in place to cut off or curtail the supply of heroin, or heroin that is laced with super potent opioids like fentanyl. Deaths from prescription opioids are declining, while deaths from heroin and fentanyl are climbing. Indeed, prescriptions for opioids drugs have fallen between 12 -25%, but the overdoses deaths have not declined. 

Yes, buprenorphine is being diverted, but most experts believe that is due to the lack of treatment. Patients desperately seeking treatment are purchasing the drug on the streets. Many experts believe that if patients have expanded and easier access to buprenorphine, the diversion will drastically reduce and more patients will be in treatment and get away from heroin.

Several steps have been taken to address this catastrophic problem, but these steps are woefully inadequate. Expansion of the needle-exchange programs and the widespread distribution of the opioid overdose drug naloxone (better known by the brand name Narcan) are welcome and should be expanded, but they are at best palliative in nature. These measures do little to address the underlying addiction.

The federal government is increasing the patient limits for buprenorphine for selected specialists from 100 to 275, and will also allow nurse practitioners and physician assistants to complete the required training and obtain the DEA exemption to prescribe buprenorphine. These are welcome steps, but fall far short of the response required to expand treatment and reduce deaths. 

You got elected on a law-and-order platform and a promise to reduce the flow of heroin coming in from Mexico. Almost 50 years ago, Richard Nixon got elected on a similar platform.  He too faced an unprecedented public health epidemic of heroin addiction – one that is nowhere close to what we are facing today.  

President Nixon is remembered for taking a bold measure, which at that time was controversial. He initiated the opening of methadone clinics, which for the first time provided evidence-based treatment for heroin addicts. This measure reduced overdose deaths, protected society from criminal activity, and allowed these patients to become productive members of society.  For the first time in the dark and checkered history of our nation, addiction was treated as a chronic healthcare issue and not a criminal activity. 

Nixon went a step further to curb the supply of heroin coming into this country. He put political pressure on France to shut down the illegal labs processing Turkish-grown opium into heroin. Turkey also complied with the strong U.S. demand to curb the illegal cultivation of opium. Who can forget The French Connection, the thriller movie about this operation.

Mr. Trump, you have an extraordinary opportunity to lift the present restrictions on buprenorphine through executive order, to lure patients away from heroin and drastically reduce overdose deaths. Your action would provide increased treatment and not just palliative care.

Furthermore, you are in the best position to bring pressure on Mexico to eliminate the opium processing labs and drastically reduce heroin coming into this country.  An epidemic is best treated when effective treatment is combined with eliminating factors contributing to the spread of the epidemic. In this case, it is the supply of heroin.

This one single action will earn you the gratitude of tens of thousands of families terrified at hearing a knock on the door informing them of the death of a loved one. You will also earn the gratitude of millions of patients suffering from chronic pain, who have been needlessly cut off from prescription opioids because of the overreaction of regulators and many physicians.

You will be remembered in history for a bold action that saved a generation from succumbing to a man-made epidemic.

New Rule Expands Access to Buprenorphine

By Pat Anson, Editor

This week marks the start of a major expansion in access to buprenorphine – a medication that is both widely praised for treating opioid addiction and also blamed for fanning the flames of abuse and diversion.

The Department of Health and Human Services (HHS) updated a federal rule, nearly tripling the number patients that can be treated with buprenorphine by an eligible physician.

Raising the limit from 100 to 275 patients is intended to give addicts greater access to buprenorphine, especially in rural areas where few doctors are certified to prescribe the drug. According to HHS, over two million people who are dependent on heroin and other opioids could benefit from buprenorphine treatment.

“For too long, addiction specialists like me have had to turn patients in need away from treatment that might save their lives, not because we don’t have the expertise or capacity to treat them, but because of an arbitrary federal limit,” said Dr. Jeffrey Goldsmith, President of the American Society of Addiction Medicine .

But critics of the rule change say there will be a price to pay.

“Buprenorphine is one of the most abused pharmaceuticals in the world,” warns Percy Menzies, president of Assisted Recovery Centers of America, which operates four addiction treatment clinics in the St. Louis area.

“Sales of buprenorphine formulations have exceeded $2 billion a year, but we have not had any lessening of heroin addiction. Increased access to buprenorphine and increased availability of potent heroin and heroin laced drugs like fentanyl will only exacerbate the problem.”

The problem with buprenorphine is that it’s an opioid that can be used to treat pain or addiction. When combined with naloxone, buprenorphine reduces cravings for opioids and lowers the risk of abuse. For many years the drug was sold exclusively under the brand name Suboxone, but it is now produced by several different drug makers and is sold in tablets, sublingual films and even an implant.

Addicts long ago discovered that buprenorphine can also be used to get high or to ease their withdrawal pains from heroin and other opioids. Buprenorphine is such a popular street drug that the National Forensic Laboratory Information System ranked buprenorphine as the third most diverted opioid medication in the U.S. in 2014. 

“Too many physicians erroneously believe that naloxone in the formulation makes the drug safe,” Menzies said in an email to Pain News Network. “Increasing the limit is definitely going to increase diversion. The majority of the physicians prescribing buprenorphine do not provide any comprehensive relapse prevention counseling, random drug testing, etc. In the absence of standards for treating addictive disorders, anything goes and will be no different than treating chronic pain.

“We saw the problem with prescription opioids when opioids were promoted as safe and non-abusable in the treatment of chronic pain. Very quickly the numbers grew into the tens of millions and the addiction exploded. The unintended victims were the patients in genuine chronic pain.”

Menzies uses buprenorphine as an initial treatment for opioid addiction in his clinics, but prefers another medication -- naltrexone -- for long-term maintenance therapy. He says doctors who rely on buprenorphine exclusively will, in effect, be sentencing their patients to lifetime use of the drug.     

"Financial Opportunity" for Doctors

HHS acknowledges there could be “unintended negative consequences” to increased prescribing of buprenorphine. One is diversion. Another is an increase in patient volume, physician profits and buprenorphine “pill mills” – which are already popping up in states like Florida. Patients typically pay cash for buprenorphine at those clinics and receive little or no addiction counseling or services.  

“This proposed rule directly expands opportunities for physicians who currently treat or who may treat patients with buprenorphine,” HHS said in an extensive analysis of the rule change. “We believe that this may translate to a financial opportunity for these physicians.”

HHS estimates the cost of treating new buprenorphine patients at up to $313 million in the first year alone. Many of the patients are low-income and the bills for treating them – about $4,300 annually for each patient – will often be covered by Medicaid. The additional cost of treating these patients, according to HHS, will be offset by the health benefits achieved by getting addicts into treatment, which the agency generously estimates at $1.7 billion.

The Obama administration asked Congress for nearly $1 billion in additional funding to help pay for addiction treatment, but didn’t get it in when Congress passed the Comprehensive Addiction and Recovery Act (CARA Act). The President reluctantly signed the bill into law anyway.

A little noticed provision of the CARA Act is that it expands access to buprenorphine even further. Currently only a trained and certified physician can prescribe buprenorphine, but CARA requires HHS to update its rules within 18 months to allow nurse practitioners and physician assistants to prescribe buprenorphine, provided they undergo training first.

How can buprenorphine diversion be prevented when access to it is rapidly increasing?

One solution proposed by Menzies is to change the classification of buprenorphine from a Schedule III controlled substance to a Schedule II drug – the same classification change that hydrocodone went through in 2014. Such a move would limit buprenorphine prescriptions to an initial 90-day supply and require patients to see a doctor for a new prescription each time they need a refill.

“We are caught between a rock and a hard place. We need to increase access to buprenorphine and it will lead to increased diversion and abuse, and therefore I am recommending changing the schedule,” Menzies said in his email to PNN.

“This is the psychotic state of affairs! No chronic condition/disease/disorder has ever been successfully treated with an addicting drug and we think we can do it for opioid addiction!”

Belbuca Effective in Treating Pain Long Term

By Pat Anson, Editor

A new opioid film designed to be taken orally twice a day significantly reduces pain and the need for breakthrough pain medication in patients with moderate to severe pain, according to a new clinical study by Endo International (NASDAQ: ENDP). The results of the Phase III study were released this weekend at the International Conference on Opioids in Boston.

Belbuca is the only analgesic formulation of buprenorphine in a sublingual film that is dissolved in the mouth and absorbed through the inner lining of the cheek.

Buprenorphine is an opioid classified as a Schedule III controlled substance, which means it has lower abuse potential than Schedule II drugs, a category that includes opioids such as hydrocodone. Buprenorphine is also used to treat addiction when combined with naloxone.

Over 400 patients with moderate to severe pain took Belbuca for 48 weeks after being titrated to find the most effective dose. During long term treatment, the average daily pain score was about 3 on a scale of 0 (no pain) to 10 (worst pain imaginable).

The need for daily rescue medication to relieve breakthrough pain decreased from an average of 3 tablets to 1.1 tablets.

"Many patients living with chronic pain require long-term treatment to control their suffering, so it is important that patients have options to manage their pain," said Martin Hale, MD, Medical Director of Gold Coast Research, one of the study's investigators. "These new findings support the safety and tolerability of treatment with Belbuca across a broad range of dosage strengths.”

About half of the patients (54%) experienced some type of side effect, including nausea, constipation, headache, vomiting and upper respiratory tract infection.

Belbuca was approved by the U.S. Food and Drug Administration in October 2015 for use in patients with pain severe enough to require daily, around-the-clock, long-term opioid treatment and for which alternative treatments are inadequate.

Belbuca utilizes a drug delivery system developed by BioDelivery Sciences (NASDAQ: BDSI). Because the oral film delivers buprenorphine into the bloodstream faster than pills or skin patches, lower doses are needed to treat pain. The film contains one-tenth to one-twentieth the amount of buprenorphine as Suboxone and other products that are used to treat opioid addiction.

Belbuca is available in seven different dosages, allowing physicians to titrate Belbuca to a tolerable dose that provides pain relief with fewer side effects. According to the Healthcare Bluebook, a 75mcg, 60-day supply of Belbuca should cost about $265.

FDA Approves New Drug Implant

By Pat Anson, Editor

The U.S. Food and Drug Administration has approved the use of a new drug implant for the treatment of opioid addiction.  Probuphine is the first implant of its kind approved by the agency and could potentially be a game changer for other medical conditions such as chronic pain that require steady doses of medication around-the-clock.

Probuphine is designed to be inserted into the arm beneath the skin, where it delivers a low dose of burprenorphine directly into the bloodstream for up to six months.  

Buprenorphine is an opioid itself, but when combined with naloxone, the medication reduces cravings for opioids. Until now the drug has only been available as a pill or film strips placed under the tongue.

For many years buprenorphine was sold exclusively under the brand name Suboxone, but several pharmaceutical companies have entered the lucrative addiction treatment market and now make versions of their own. As many as 2.3 million people who are dependent on opioid pain medication or heroin could benefit from buprenorphine treatment,

FDA approval was a major win Braeburn Pharmaceuticals and its partner, Titan Pharmaceuticals (OTC: TTNP), which holds the rights to the implant technology. Titan and Braeburn were stunned in 2013 when the FDA denied approval of the implant and asked for new clinical studies proving Probuphine’s effectiveness.  

Results from a recent Phase III study showed that over 85% of the patients who had the implant abstained from using illicit opioids for six months, compared to about 72% of patients who used buprenorphine film strips that were taken daily.

"Opioid abuse and addiction have taken a devastating toll on American families. We must do everything we can to make new, innovative treatment options available that can help patients regain control over their lives,” said FDA Commissioner Robert Califf, MD. “Today’s approval provides the first-ever implantable option to support patients’ efforts to maintain treatment as part of their overall recovery program.”

Expanding the availability of addiction treatment is a major goal of the Obama administration. The White House has asked Congress for an additional $1.1 billion to fight opioid abuse, with much of the money earmarked for addiction treatment. The administration has also proposed doubling the number of patients that doctors can treat with buprenorphine from 100 to 200.

Buprenorphine can be abused and is a popular street drug that is used to get high or to ease withdrawal pains from illegal opioids such as heroin. An implant will be much more difficult to abuse, since it can’t be crushed or liquefied for snorting or injecting. It’s also less likely to be diverted.

Probuphine is expected to cost about $1,000 a month. It consists of four, one-inch-long rods that are implanted under the skin on the inside of the upper arm. Administering Probuphine will require special training because it must be surgically inserted and removed.

The most common side effects are pain at the implant site, as well as itching, redness, headache, depression, constipation, nausea, vomiting, back pain, toothache and oral pain. The FDA is requiring post-marketing studies to establish the safety and effectiveness of the implants.

Probuphine was developed using a patented implant technology called ProNeura, which is designed to provide continuous levels of medication in the blood. Titan is also developing implants to treat Parkinson’s disease and hypothyroidism, and its CEO told Pain News Network that ProNeura could also potentially be used to deliver pain medication.

“Clinical studies will need to be done to establish the ability, but the drug levels can certainly be delivered that are going to be beneficial for treating chronic pain,” said Titan CEO and President Sunil Bhonsle. “There are many applications for this technology and I think the medical community is now more in tune with looking at long-term delivery technology in the chronic disease setting.”

“It is part of our plan to move into pain because pain and opioid addiction are so interconnected and we think there are ways, by treating patients with a less abuse-able formulation, you could actually help alleviate the addiction problem,” Behshad Sheldon, President and CEO of Braeburn, told PNN in an earlier interview.

The Coming ‘Economic Bonanza’ in Addiction Treatment

By Pat Anson, Editor

The addiction treatment industry is lobbying hard for a proposed rule change to expand the number of patients that doctors can treat for opioid addiction. At stake is hundreds of millions of dollars in potential new business, much of it paid for by taxpayers.

The Obama administration has proposed doubling the maximum number of patients that a doctor can prescribe with buprenorphine from 100 to 200. Buprenorphine is an opioid that can be used to treat both pain and addiction. When combined with naloxone, buprenorphine reduces cravings for opioids and lowers the risk of abuse.

For many years the drug was sold exclusively under the brand name Suboxone, but it is now produced by several different drug makers and generates nearly $2 billion in sales annually.

Because buprenorphine is an opioid that can also be abused, prescribers have to register with the Drug Enforcement Administration and undergo special training. Over 33,000 doctors have done so, but most are limited to just 30 patients.

About 10,000 physicians are currently allowed to prescribe buprenorphine to the maximum number of 100 patients.

Many addiction experts say the patient limits have restricted access to a valuable treatment tool, especially in rural areas where fewer doctors are certified to prescribe buprenorphine. According to the Health and Human Services Department (HHS), about 2.3 million people who are dependent on opioid pain medication or heroin could benefit from buprenorphine treatment, but many lack access to the drug because of limits on prescribers.

In a joint letter to HHS Secretary Sylvia Burwell, the American Psychiatric Association, American Academy of Addiction Psychiatry, and the American Osteopathic Academy of Addiction Medicine stated that as “the number of people addicted to these opioids increases, there continues to be a shortage of physicians who are appropriately trained to treat them. The shortage severely complicates and impairs our ability to effectively address the epidemic, particularly in many rural and underserved areas of the nation.”  

While the goal of treating opioid addiction is laudable, little attention has been paid to the diversion of buprenorphine or the financial incentives that doctors have to prescribe it.

“This proposed rule directly expands opportunities for physicians who currently treat or who may treat patients with buprenorphine,” HHS says in an extensive analysis of the rule change. “We believe that this may translate to a financial opportunity for these physicians.”

HHS broadly estimates the added cost of treating new patients at between $43.5 million and $313 million in the first year alone. Many of the patents are low-income and the bills for treating them – about $4,300 annually for each patient – will often be paid by Medicaid. The Obama administration has asked Congress for an additional $1.1 billion to fight opioid abuse, with much of the money earmarked for addiction treatment.

The additional cost to taxpayers for expanding buprenorphine treatment, according to HHS, will be more than offset by the health benefits achieved by getting opioid addicts into treatment, which the agency generously estimates at $1.7 billion in the first year.

But some addiction experts have sounded a note of caution, warning that buprenorphine prescribing has already become a lucrative cash cow for some unscrupulous doctors.

“In northeast Tennessee, I am not aware of any buprenorphine provider that accepts insurance. Here buprenorphine clinics charge $100 cash at the time of service and require weekly visits for refills. This amounts to a cost to patients of over $5,000 yearly for medical services. This is a significant economic barrier for patients who typically have little or no income,” wrote Jack Woodside, MD, a professor at East Tennessee State University College of Medicine, in a public comment on the proposed rule change.

“From the provider's perspective, collecting $5,000 yearly from 100 patients amounts to an annual gross income of $500,000, with low overhead and no costs associated with billing insurance. This economic bonanza is causing many physicians to abandon traditional medical practices. A primary care physician remarked that he earns as much in one day in the buprenorphine clinic as he does the rest of the week in primary care.”

Buprenorphine Abuse

HHS acknowledges there could be “unintended negative consequences” to increased prescribing of buprenorphine – one of them being diversion.  Buprenorphine is a popular street drug, with addicts using it to either get high or to ease their withdrawal pains from illegal opioids like heroin. In 2014, the National Forensic Laboratory Information System ranked buprenorphine as the third most diverted opioid medication in the U.S. 

Some experts say the drug naltrexone is a better treatment option than buprenorphine. Naltrexone also reduces cravings, but it is not an opioid and is non-addicting.

“As I have been saying for longest time, buprenorphine is a double-edged sword. I contend greatly expanding the access of opioids contributes to the spread of addiction and a major factor in relapse,” said Percy Menzies, president of Assisted Recovery Centers of America, which operates four addiction treatment clinics in the St. Louis area.

“We are seeing more and more patients getting exposed to heroin and it is going to get worse. Sadly, the heroin addiction is being sustained by buprenorphine preparations.”

A 2013 study by the Substance Abuse and Mental Health Services Administration (SAMHSA) found a ten-fold increase in the number of emergency room visits involving buprenorphine. Over half of the hospitalizations were for the "non-medical" use of buprenorphine – meaning many users took the drug to get high.

“It is important to note that studies have found that the motivation to divert buprenorphine is often associated with lack of access to treatment or using the medication to manage withdrawal—as opposed to diversion for the medication's psychoactive effect.  Thus, the overall effect of this rulemaking on diversion is not clear,” HHS says in its analysis.

Clear or not, many of the same government regulators and anti-opioid activists who want to restrict access to opioid pain medication are some of the biggest supporters of expanding access to buprenorphine.

They include Andrew Kolodny, MD, the founder and Executive Director of Physicians for Responsible Opioid Prescribing (PROP), a program funded by Phoenix House, which operates a chain of addiction treatment centers in 10 states and the District of Columbia. 

Kolodny, who is Phoenix House’s chief medical officer, has long advocated the use of buprenorphine, calling it “one of the most effective medications for opioid addiction” on C-SPAN last year. During the same interview, Kolodny likened other opioid pain medications to “heroin pills.”

Kolodny declined to comment to Pain News Network for this story.

Patient Limits “Indefensible”

Under the proposed rule change, only doctors who are certified in addiction medicine or addiction psychiatry will be eligible for the expanded limit on buprenorphine prescribing. The rule changes also favor physicians in larger “qualified practices” – excluding many primary care physicians and other doctors who don’t offer additional therapies such as addiction counseling.

HHS is accepting public comment on the rule change until the end of this month. The vast majority of the nearly 300 comments received so far are from doctors, including many who are angry that the restrictions on buprenorphine aren’t being loosened further:

“The current limit is indefensible. There are not enough doctors now who are willing to deal with addicted patients, there is no need to further limit which doctors can treat more patients. The goal should be to get as many doctors as possible treating as many patients as they can comfortably handle,” wrote Jon Robertson, MD.

“We should have an immediate increase in the number of opiate addicts/heroin addicts we can treat with buprenorphine. We should have an unlimited number of patients we can treat,” said Peter Rogers, MD. 

“Why is it that I can give 10,000 patients OxyContin, yet I cannot meet the need in my community to treat addiction? No other specialty of medicine, no other physician, has any limit on any prescribing, especially during an epidemic,” wrote Anne Pylkas, MD.  “I am not a thief, I am not a charlatan or a quack. I am not a pill mill. I take insurance. I do not make millions on the backs of the helpless.”

 “It makes no sense to limit physicians to an arbitrary number of patients that can be treated to get the patients out of opiate addiction,” wrote Raymond Moy, MD. “Instead of making it hard to treat opiate addicts, why don't you make it harder to create opiate addicts? Make all these regulations apply to doctors prescribing opiates.”

“I practice in a rural area with a shortage of physicians to treat opioid addiction. My staff is capable of treating many more than 100 patients, so our contributions to the community's health are hampered by the current limits,” said Nels Kloster, MD, who runs a treatment center in Vermont. “There are many more persons seeking this treatment, but we have to turn them away due to this artificial restriction to our services.”

Only a few commenters warned that buprenorphine is already widely available on the black market and some doctors are likely to abuse the system.

“While it seems logical that increasing the patient limit would increase the ability to get people into the system, it does have some very serious downsides,” wrote Karl Hafner. “Several of these providers (at least in our area) are what most would consider pill mills. This only puts more medication on the street for abuse.

"By increasing the limit you will move physicians from doing this as part of a practice to just doing Suboxone and they will become pill mills. Do not increase the cap unless it is tied to treatment programs. There are plenty of providers.”

In a recent column in the Journal of Psychiatric Practice, one expert also warned of unintended consequences if the cap on buprenorphine prescribing is raised.

“Buprenorphine is an effective treatment for opioid use disorder; however, with increased access and availability, its abuse and diversion may be inevitable,” warned Daryl Shorter, MD, Department of Psychiatry and Behavioral Sciences, Baylor College of Medicine.

“This real-world, almost paradoxical, phenomenon demonstrates the complexity inherent in the treatment of addictive disorders -- a medication intended to treat substance use disorder that has its own abuse potential, upon gaining popularity and increased availability, will inevitably be explored by drug abusers for reward and reinforcement purposes.”

FDA Nearing Decision on Drug Implant

By Pat Anson, Editor 

The U.S. Food and Drug Administration is expected to finally make a decision next month on a new drug delivery system to treat opioid addiction – an implant that could also be used someday to treat pain and other chronic illnesses that require steady doses of medication.

The latest results from a Phase 3 double blind study of a buprenorphine implant called Probuphine would appear to boost its chances of winning FDA approval. Titan Pharmaceuticals (NASDAQ: TTNP) said over 85% of the patients who had the implant for six months abstained from using illicit opioids, compared to about 72% of patients who used oral buprenorphine film strips that were taken daily.

The study findings were recently presented at the annual meeting of the American Society of Addiction Medicine in San Francisco.

"This was the first head-to-head comparison study of Probuphine and sublingual buprenorphine, demonstrating the efficacy of a long-acting six month buprenorphine implant," said lead investigator Richard Rosenthal, MD, Professor of Psychiatry and Medical Director of Addiction Psychiatry at the Icahn School of Medicine at Mount Sinai. “If approved, Probuphine could help expand access to medication to treat opioid use disorders, providing people with a new option."

Probuphine is about the size of a matchstick and is implanted under the skin. For six months it delivers a steady dose of buprenorphine, a weaker acting opioid that’s long been used as an addiction treatment drug sold under the brand name Suboxone.

There are many advantages to an implant. The dosage is controlled and there’s little risk of abuse, diversion or overdose. Users also never have to remember to take a pill.

Probuphine’s path to the marketplace has been rocky at times. Titan and its partner, Braeburn Pharmaceuticals, were stunned in 2013 when the FDA denied approval of the implant and asked for a new clinical study proving Probuphine’s effectiveness.  

Positive results from a Phase 3 trial were submitted in 2015 and in January of this year an FDA advisory committee voted 12 to 5 in favor of approving the implant. But then the agency added another delay by extending its decision date to May 27.  

The time may be ripe for approval this time around, as the FDA is under intense political pressure to do more to address the nation's opioid abuse epidemic. The Obama administration has proposed a rule change that would double the number of patients that a doctor can treat with buprenophine from 100 to 200. And Congress is considering funding proposals that would allocate another $1 billion to the war on drugs, with most of the money spent on addiction treatment.

Probuphine was developed using a patented implant technology called ProNeura, which is designed to provide continuous levels of medication in the blood. Titan is also developing implants to treat Parkinson’s disease and hypothyroidism, and its CEO told Pain News Network in a recent interview that ProNeura could also potentially be used to deliver pain medication.

“Clinical studies will need to be done to establish the ability, but the drug levels can certainly be delivered that are going to be beneficial for treating chronic pain,” said Titan CEO and President Sunil Bhonsle. “There are many applications for this technology and I think the medical community is now more in tune with looking at long-term delivery technology in the chronic disease setting.”

White House Steps Up Anti-Opioid Campaign

By Pat Anson, Editor

The Obama administration has unveiled a series of new initiatives aimed at treating addiction and educating doctors about prescription opioid abuse – amid growing signs the nation’s drug abuse epidemic is being fueled more and more by illegal opioids such as heroin and illicit fentanyl.

The new campaign, unveiled at the National Rx Drug Abuse and Heroin Summit in Atlanta, expands on a $1.1 billion funding proposal the President sent to Congress last month to address the nation’s growing drug problem.

One change that could greatly expand access to addiction treatment is a proposed rule by the Department of Health and Human Services (HHS) to double the number of prescriptions that a doctor can write for buprenorphine, an opioid used to treat addiction. Doctors currently are limited to 100 buprenorphine patients, but the new rule would expand that to 200 patients. The number of doctors trained and licensed to prescribe buprenorphine will also be increased.

HHS and the Substance Abuse and Mental Health Services Administration (SAMHSA) will also release over $100 million to expand access to addiction treatment.

"Expanding access to medication-assisted treatment for opioid-use disorders has been a top priority for this administration. Research clearly shows that this approach, when combined with behavioral therapies, is more effective at sustaining recovery and preventing overdose," said Michael Botticelli, director of the White House Office of National Drug Control Policy.

The policy changes and funding support stand to greatly benefit addiction treatment centers such as Phoenix House, whose medical director has lobbied for expanded access to buprenorphine treatment. Andrew Kolodny, MD, is also the founder and Executive Director of Physicians for Responsible Opioid Prescribing (PROP) which had five board members, including Kolodny, advising the CDC about its new opioid prescribing guidelines.

While buprenorphine is considered a “safer” opioid and has long been used to treat addiction (under the brand name Suboxone), it is prized by some addicts and can be abused. A 2013 study by SAMHSA found a ten-fold increase in the number of emergency room visits involving buprenorphine. Over half of the hospitalizations were for non-medical use of buprenorphine – meaning many users took the drug to get high.

“One of the most effective medications for opioid addiction is a drug called buprenorphine or Suboxone,” said Kolodny in an interview on C-SPAN last October.

A request to Phoenix House and Kolodny for comment on the HHS buprenorphine proposal went unanswered.

The White House also announced this week that 60 medical schools will require students to take some form of prescriber education, modeled after the CDC’s opioid guidelines, in order to graduate.

The lack of pain education in medical schools has long been recognized as a problem. A 2012 study published in the Journal of Pain called pain education "lackluster" in the U.S. and Canada. Few schools required a course in pain education and many did not have any pain courses.

A recent survey by Pain News Network and the International Pain Foundation (IPain) found that 8 out of 10 patients feel that hospital staffs are not adequately trained in pain management. Over half rated the quality of their pain care in hospitals as either poor or very poor.

Some fear the new White House plan is focused more on addiction treatment and limiting access to opioids than it is on educating doctors about pain management.  

“What remains astonishing is the total deafness to the needs of people in pain. It is as if people in pain don't exist and that they are not important,” said Lynn Webster, MD, past president of the American Academy of Pain Medicine and vice president of scientific affairs at PRA Health Sciences.

“Focusing on opioid prescribing education in medical schools without also educating medical students about pain medicine is only going to further stigmatize people in pain and those who develop addictions. This is a true Back to the Future nightmare.  We will be practicing 1950's medicine for the most prevalent public health problems in America.  Absolutely astounding to me.”  

Six Fatal Fentanyl Overdoses in California

While the Obama Administration was announcing its new plan, health officials in Sacramento, California confirmed that six people died and over two dozen were hospitalized this month after ingesting a black market version of Norco, a widely prescribed opioid painkiller.

Legitimate Norco pills are a combination of hydrocodone and acetaminophen, but the “street” Norco was laced with fentanyl, a much more potent and potentially deadly opioid. Fentanyl is odorless and cannot be easily distinguished from other drugs.

“Some who have taken it stated that they were told that it was Norco.  However, results just released indicate that some of the pills that were retrieved have been tested and show that they did not contain Hydrocodone or Acetaminophen. The lab was able to identify the pills as containing Fentanyl instead.  This indicates that they are really Fentanyl pills that have been made to look like Norco,” the Sacramento County Division of Public Health said in a statement.

Fentanyl deaths have been rising around the country – at least 22 died from fentanyl overdoses in the Cleveland, Ohio area this month alone and dozens of deaths have been reported in West Virginia.

Last year the Drug Enforcement Administration issued a nationwide alert about the abuse, diversion and illegal manufacture of fentanyl. Thousands of people are believed to have died from fentanyl overdoses, but because of the nature of the drug it is impossible to tell whether it was prescribed legally and used for medical reasons or manufactured illegally and used recreationally. The CDC admits many fentanyl overdoses may have been misclassified as deaths caused by prescription painkillers.

Meanwhile, a report this week in Maine’s Portland Press Herald suggests that there is a correlation between rising heroin use and reduced access to prescription opioids. In recent years the number of people being treated for heroin addiction has nearly tripled in Maine, at a time when the number of prescriptions written for opioids dropped by 45 percent.

FDA Committee Approves New Drug Implant

By Pat Anson, Editor

An advisory committee to the U.S. Food and Drug Administration has approved a new drug delivery system to treat opioid addiction – an implant that could potentially be used to treat chronic pain and other diseases that require steady doses of medication.

The FDA’s Psychopharmacologic Drugs Advisory Committee voted 12 to 5 in favor of the new drug application for Probuphine, a tiny implant about the size of a matchstick that contains buprenorphine, a drug already used to treat addiction that currently only comes in pills and oral film strips. The FDA is expected to make a final decision on Probuphine next month.

“You can never be 100 percent sure of anything,” said Sunil Bhonsle, CEO and president of Titan Pharmaceuticals (NASDAQ: TTNP), which partnered with Braeburn Pharmaceuticals in developing the implant. “The data clearly shows that this product can be of benefit to this patient population. And we hope the FDA will approve it.”

COURTESY BRAEBURN PHARMACEUTICALS

Once implanted under the skin, Probuphine is designed to deliver a steady dose of buprenorphine for six months. Buprenorphine is a weaker opioid that’s long been used as an addiction treatment drug sold under the brand name Suboxone. While it reduces cravings for opioids, buprenorphoine can also be abused and is prized by addicts as a street drug that can ease withdrawals pains from heroin.

The advantages of an implant are many. The dosage is controlled and there’s hardly any risk of abuse, diversion, or accidental overdose. Users also never have to remember to take a pill.

Probuphine’s path to the marketplace hasn’t been a smooth one. Braeburn and Titan were stunned in 2013 when the FDA denied approval of the implant and asked for a new clinical study proving Probuphine’s effectiveness in treating opioid addiction.

The results of a six month, double-blind clinical trial on 177 patients, found that the implant was more effective than buprenorphine film strips in treating addiction. The implant’s insertion and removal were "generally well tolerated," although nearly one in four patients had a "mild" adverse event at the implant site.

Several members of the FDA's advisory committee, including its chairwoman, voted against approval, saying there was not enough evidence of Probuphine’s effectiveness after six months.   

"New treatment options for the millions of patients and their families suffering from opioid addiction are desperately needed, and we appreciate the Committee's comprehensive review of Probuphine," said Bhonsle. “There are many applications for this technology and I think the medical community is now more in tune with looking at long-term delivery technology in the chronic disease setting. So I think it’s probably accurate to say the time is right to expand the use of these technologies to different settings.”

Bhonsle says Titan is already looking at ways the implant can be used to treat Parkinson’s disease and hypothyroidism, adding that chronic pain could also be treated with an implant.

“Clinical studies will need to be done to establish the ability, but the drug levels can certainly be delivered that are going to be beneficial for treating chronic pain,” he told Pain News Network.    

Will CDC Guidelines Promote Addiction Treatment?

By Alison Knopf, Editor of Alcoholism & Drug Abuse Weekly

The quick answer to the question “Will treatment providers be able to treat patients coming in addicted to opioids because they have been thrown off their pain medications next year?” is no. The treatment system can’t even treat all the patients who need help now. But this question is on the minds of federal policymakers as the federal Centers for Disease Control and Prevention (CDC) works on its forthcoming guidelines for physicians on prescribing opioids, due out next January (see ADAW, Nov. 16).

While the pain community is creating the loudest noise about the forthcoming guidelines, charging that they are not addicts and don’t want to be lumped in with them, the treatment community has on the one hand seen the benefits of decreasing the amount of prescription opioids available, but also seen the downside: patients who are dependent or addicted, who cannot successfully taper off the pain medications, will switch to heroin. Many started as legitimate pain patients.

But for some, when their doctors felt they no longer needed the pain medication, or thought the patient was doctor-shopping, or simply decided to go along with the calls to reduce the amount of prescriptions for opioids, it was difficult to stop, and they sought illicit sources of opioids.

The CDC confirmed to ADAW that there will be a guideline that “addresses treatment for opioid use disorder.” The draft guidelines leaked in September specifically recommended that an opioid agonist (methadone or buprenorphine) be arranged for patients who need treatment for an opioid use disorder. The CDC said the guidelines are continuing to be revised. Below is the wording of that recommendation from the September draft:

“Providers should offer or arrange evidence-based treatment (usually opioid agonist treatment in combination with behavioral therapies) for patients with opioid use disorder.”

SAMHSA Working With CDC

But how the primary care physician determines whether a patient has an opioid use disorder is unclear. The Substance Abuse and Mental Health Services Administration (SAMHSA) expects there to be a change in prescribing practices — that’s the whole point of the guidelines. But according to Robert Lubran, director of the Division of Pharmacologic Therapies at SAMHSA’s Center for Substance Abuse Treatment (CSAT), it’s up to the physicians who are prescribing the medications to come up with a referral plan for their patients.

“I go back to what Westley Clark always said,” Lubran told ADAW, referring to the former director of CSAT. “He said the physician has to have an exit strategy for a patient he isn’t going to be prescribing opioids for anymore.” The physician has to determine if the patient is dependent on or addicted to the medication. Dependence is a normal result of regular opioid intake, addiction is pathological, but both will result in withdrawal symptoms when opioids are stopped suddenly. Someone who is dependent can be slowly tapered off the opioids and endure the craving that ensues. Someone who is addicted cannot stop and will seek opioids from another source.

“There has to be a place where the doctor can refer someone when the doctor determines that the patient can’t be safely tapered down because they are addicted,” said Lubran. A treatment provider specializing in opioid use disorders, such as an opioid treatment program (OTP) or office-based opioid treatment (OBOT), would be a good solution, he said. “We’re working with the CDC to make sure the guidelines include information on where to refer these patients,” Lubran told ADAW.

“We’re already struggling on the traditional medicine side with how a patient goes from being a pain patient to being an addict,” said Lubran. “They discharge them, but what about referrals? More states and counties need to be involved in recommendations for care,” said Lu, adding that insurance companies need to be involved as well.

Guidelines Not Mandatory

Mark Parrino, president of the American Association for the Treatment of Opioid Dependence (AA-TOD), said that as far as he knows, OTPs have not been involved in the development of the CDC guidelines. However, he expressed skepticism about the effect of the guidelines. “Will there be a reaction by physicians? Will this really change their practice patterns? Will there necessarily be a wholesale dumping of patients who are getting pain medications? I would hope not. But if that is the result, I would ask how we are going to know whether these patients will show up in treatment, or go into the street for drugs?”

Furthermore, said Parrino, these are just guidelines from the CDC. “Doctors aren’t even required to read the stuff,” he said. “They’ll issue a big press statement, yes. But it’s like package inserts. Do you really think every physician will be watching their computer for the guide-lines, saying ‘Now I need to change my medical practice?’”

The CDC itself says as much. “It is important to note that, like other CDC guidelines, including prevention and treatment of sexually treated diseases, the guidelines are intended to support informed clinical decision-making but are not mandatory (that is, physicians are not required to follow these guidelines),” according to Courtney Lenard of the CDC’s press office. The CDC’s guide-line is meant to “help primary care doctors provide safer, more effective care for patients with chronic pain” and at the same time “help reduce use, abuse and overdose from these powerful drugs,” the CDC’s press office told us last week. “The guideline is intended for primary care providers who treat adult patients (age 18 and older) for chronic pain in outpatient settings, and is not intended for patients who are in active cancer treatment, palliative care or end-of-life care.”

Asked if restrictions on prescription opioids will lead to increased use of heroin, however, the CDC continued to stick to the federal official answer, which is: No. “There is no robust evidence that recently enacted policies regarding prescription opioids are responsible for large-scale shifts to heroin,” said Lenard, adding that only 1 in 25 people who use prescription opioids nonmedically start using heroin within five years. However, she added that this “translates into a major and growing epidemic of heroin use given how widespread the misuse of prescription opioids has become.” Stopping the misuse of prescription opioids is the best way to stop the heroin epidemic, according to the CDC.

Study Finds ‘Notable Downturn’ in Opioid Abuse

By Pat Anson, Editor

A “notable downturn” in the abuse of opioid pain medication in the United States is being overshadowed by a sharp rise in heroin use, according to a large new study outlined in a letter to the New England Journal of Medicine.

In the nationwide study of over 15,000 patients being treated for addiction, the number of addicts who abused opioids alone fell from 70% in 2010 to less than 50% in 2014.

At the same time, however, researchers at Washington University School of Medicine in St. Louis found that many addicts were using heroin and opioids concurrently. Forty-two percent said they had taken heroin and prescription opioids within a month of entering treatment, up from nearly 24 percent in 2008.

"We see very few people transition completely from prescription opioids to heroin; rather, they use both drugs," said lead author Theodore J. Cicero, PhD. "There's not a total transition to heroin, I think, because of concerns about becoming a stereotypical drug addict."

The use of heroin alone – although still relatively low -- more than doubled from 2008 to 2014, from 4.3% to 9% of the addicts under treatment.

Heroin has spread beyond inner cities into suburban and rural areas, according to Cicero. His research also found regional variations in the use of heroin and prescription opioids.

"On the East and West coasts, combined heroin and prescription drug use has surpassed the exclusive use of prescription opioids," Cicero said. “This trend is less apparent in the Midwest, and in the Deep South, (where) we saw a persistent use of prescription drugs -- but not much heroin.”

The study did not make clear how many of the addicts were legitimate pain patients who took opioids to relieve their pain or whether they were recreational users who started taking opioids to get high.

Cicero says a crackdown on "pill mills" and doctors overprescribing opioids has made it harder to get the drugs. For those who are addicted, heroin has become the new drug of choice.

"If users can't get a prescription drug, they might take whatever else is there, and if that's heroin, they use heroin," he said.

Heroin is more accessible and cheaper today, said Percy Menzies, president of Assisted Recovery Centers of America, which operates four addiction treatment clinics in the St. Louis area.

“Political events triggered the present heroin problem. 90% of the world's heroin comes from just three countries - Afghanistan, Burma and Mexico. The Afghan and Burmese heroin was a perfect cash crop for insurgency groups and the heroin addiction spread rapidly in countries bordering Afghanistan and Burma. Mexico is a bigger problem for us because farmers in that country have switched to growing the poppy,” said Menzies in an email to Pain News Network.

Opioids aren’t the only “gateway” drug to heroin, according to Menzies. He believes the increasing use of buprenorphine (Suboxone) to treat addiction is fueling the heroin epidemic because addicts have found they can use the drug to ease systems of withdrawal.

“We are seeing more and more patients getting exposed to heroin and it is going to get worse. Sadly, the heroin addiction is being sustained by buprenorphine preparations,” Menzies said.

Menzies has more to say about buprenorphine, marijuana legalization, and "the coming tsunami" in heroin use in this guest column.

FDA Approves New Opioid Film Patch

By Pat Anson, Editor

The U.S. Food and Drug Administration has approved a new delivery system for the treatment of chronic pain – the first of its kind to use an oral film patch containing buprenorphine.

The film patch – which will be sold under the brand name Belbuca -- was jointly developed by Endo International (NASDAQ: ENDP) and BioDelivery Sciences (NASDAQ: BDSI). It’s expected to become available early next year.

Belbuca is designed to dissolve in the mouth, delivering buprenorphine through the inside lining of the cheek and into the bloodstream faster than conventional pills or skin patches. Buprenorphine is a weaker acting opioid that has long been used to treat both addiction and chronic pain.

“Belbuca provides a unique approach for chronic pain management, combining the proven efficacy and established safety of buprenorphine with a novel buccal film delivery system that adds convenience and flexibility," said Richard Rauck, MD, Director of Carolinas Pain Institute in Winston Salem, NC.

"For both opioid-naïve and opioid-experienced patients who require around-the-clock treatment and for whom alternative treatment options are inadequate, Belbuca offers appropriate, consistent pain relief and a low incidence of typical opioid-like side effects.”

Because the film delivers buprenorphine into the bloodstream faster than conventional methods, lower doses are needed to treat pain. Belbuca will be available in seven different dosage strengths, allowing for flexible dosing every 12 hours.

FDA approval of Belbuca was based on two Phase III studies involving over 1,500 patients with moderate to severe chronic low back pain. Patients who used Belbuca reported “statistically significant improvement” in pain relief over a 12-week period, compared to a placebo. The most common adverse reactions to Belbuca were nausea, constipation, headache, vomiting, fatigue, dizziness, somnolence, diarrhea, dry mouth, and upper respiratory tract infection.

Buprenorphine is a Schedule III controlled substance, which means it has a lower abuse potential than many other opioids. It may also be easier to get a prescription for than Schedule II drugs such as hydrocodone.

“If you’re going to use an opioid, I think based on its classification, Belbuca really does offer some significant benefits,” said Dr. Mark Sirgo, President and CEO of BioDeliversy Sciences.

“There are two areas this product will be used for. Those that are stepping up from a Motrin-like drug, a non-steroidal anti-inflammatory, that no longer controls their chronic pain. Those are good candidates for Belbuca. And in those that may already be on a Schedule II product such as Vicodon, one of the oxycodone products or morphine products, where a physician may feel more comfortable using a buprenorphine product than a Schedule II opioid."

Sirgo says Belbuca is also less likely to abused than a pill, because the film patches are difficult to grind or liquefy for snorting or injecting.

Implant Could Be ‘Game Changer’ in Pain Treatment

By Pat Anson, Editor

Imagine going to your doctor’s office and getting an implant put in your arm that delivers a steady flow of pain medication for six months.

No more pills. No more trips to the pharmacy. No more worries about your pain medication getting lost or stolen.

That’s the scenario a New Jersey drug maker envisions for its Probuphine implant – tiny rods about the size of a matchstick designed to be inserted subcutaneously under the skin of the upper arm.

Probuphine was developed by Braeburn Pharmaceuticals under a license agreement with Titan Pharmaceuticals (OTC: TTNP), which holds the rights to the implant technology. Both companies have applied to the Food and Drug Administration to have Probuphine approved to treat opioid addiction, but Braeburn’s long term goal is to also have the implant approved for chronic pain.

COURTESY TITAN PHARMACEUTICALS

“We are definitely interested in talking to the FDA about the use of Probuphine in pain,” said Behshad Sheldon, President and CEO of Braeburn.

The active ingredient in Probuphine is buprenorphine, a weaker opioid that’s long been used as an addiction treatment drug sold under the brand name Suboxone. Buprenorphine is also used to treat chronic pain and comes in various forms – pills, patches and film strips – but none as long-acting as an implant.

The advantages of an implant are many. The dosage is controlled and there’s hardly any risk of abuse, diversion, or accidental overdose. You also never have to remember to take a pill.

“We believe a buprenorphine implant could be a really great clinical tool to treat pain,” Sheldon told Pain News Network. “There’s just a peace of mind aspect for the patients. The medicine’s on board and they don’t have to worry about it.”

“I personally would want a Lipitor implant, because I can’t manage to take it three days in a row,” she joked.

Probuphine’s path to the marketplace hasn’t been a smooth one. Braeburn and Titan were stunned in 2013 when the FDA denied approval of the implant and asked for a new clinical study of Probuphine’s effectiveness in treating opioid addiction.

Braeburn recently reported the results of a six month, double-blind clinical trial of Probuphine on 177 patients, which found that the implant was more effective than buprenorphine tablets in treating addiction. The company said the implant insertion and removal were "generally well tolerated," although nearly one in four patients had a "mild" adverse event at the implant site.

“The data from this trial are encouraging and underscore the benefit of longer term medical treatments for patients with opioid addiction. I am confident that the implant, if approved by FDA, will be at least as effective as a sublingual formulation and have the added benefits of reducing problems related to compliance, misuse and abuse,"  said Richard Rosenthal, MD, Professor of Psychiatry and Medical Director of Addiction Psychiatry at the Icahn School of Medicine at Mount Sinai.

Braeburn and Titan plan to resubmit a New Drug Application (NDA) for Probuphine to the FDA in the second half of this year.

Long Term Injection for Pain

Braeburn has formed another partnership with Camurus, a Swedish drug company, to develop an injectable buprenorphine drug to treat addiction and chronic pain -- a single injection that lasts as long as a month. Camurus has already completed successful Phase I and II studies on the drug and both companies hope to start a Phase III trial later this year -- with the goal of seeking regulatory approval in 2016.

“There have been many conversations with expert clinicians and they’ve told us that they think buprenorphine in general, in a non or less abuse-able form of buprenorphine, in either an implant or an injection could really be game changing,” said Sheldon. “It is part of our plan to move into pain because pain and opioid addiction are so interconnected and we think there are ways, by treating patients with a less abuse-able formulation, you could actually help alleviate the addiction problem.”

Sheldon admits a lot more work needs to be done before a buprenorphine implant or injection is available to treat chronic pain.

“We haven’t studied it yet in pain and we haven’t had any conversations yet with the FDA. So there’s a lot more to do to get to that point,” she said.

Another formulation of buprenorphine to treat pain may be coming to the market relatively soon. Endo International (NASDAQ: ENDP) and BioDelivery Sciences (NASDAQ: BDSI) have submitted a new drug application for a buprenorphine film patch to the FDA. The companies are hoping for FDA approval by October of this year.

Although the patch contains much smaller doses than buprenorphine tablets or patches already on the market, the companies say the film is very effective in treating pain because the drug is absorbed through the inside lining of the cheek and enters the blood stream faster.
