Is the Hype About a New Non-Opioid Analgesic Justified?

By Carol Levy

In a previous column, I asked why pharmaceutical companies haven’t been able to “build a better mousetrap” by developing new and effective non-opioid medications for pain 

Every doctor I've seen about my chronic facial pain has only offered me opioids. As is true for many of us, I hate the way they make me feel. They also rarely help, outside of making me so cloudy-headed that I become less aware of the pain and have trouble thinking clearly.

That is the exact opposite of what the drug is supposed to do. It's supposed to make me feel better, and therefore better able to work, play, and do regular activities — which is exactly what the cloudiness stops me from doing. That's not a workable trade-off.

When I protest, “There must be something other than an opioid,” the reply from doctors is always the same: “There is nothing else.”

Now there may be. The FDA is giving priority review to a new drug application for suzetrigine, an experimental non-opioid analgesic developed by Vertex Pharmaceuticals. The drug has previously been granted “Fast Track” and “Breakthrough Therapy” designations by the agency for the treatment of moderate-to-severe acute pain. Final approval could come in January, which would make suzetrigine the first new class of medication for pain in over two decades.

The upside to suzetrigine is that it’s not an opioid. That would address the lie that we are responsible for the opioid crisis, and should be held captive by doctors who fear being raided by the DEA and don’t prescribe opioids anymore.

The downside is that suzetrigine is being considered as a treatment for acute pain and perhaps chronic neuropathy. My pain is neuropathic in nature -- trigeminal neuralgia and anaesthesia dolorosa (phantom pain) --- so I was at first exhilarated, and then deflated to see that suzetrigine is only being studied as a treatment for diabetic peripheral neuropathy. I had hoped this would be something for all of us.

I Google searched for other non-opioid analgesics, hoping there might be some new ones in the process of testing or even FDA fast-tracked. I couldn't find any.

As I researched further, I began to feel dejected. All drugs have downsides. That is expected. But I had hoped the FDA’s priority review meant the research was very positive about suzetrigine. Instead, I found there are many questions as to whether the drug is any better than what is already out there.

So why is the FDA fast-tracking it? Are they so eager to approve non-opioids that anything that might work will be considered? Maybe. The breakthrough therapy and fast-track designations may be geared more towards appeasing the FDA’s critics than anything else.

The headlines sounded so promising. “New Painkiller Could Bring Relief to Millions” and “A New Class of Medicine for Pain Relief On The Horizon.”

When I found out about this drug my heart leaped. Now I am not so sure. I hope it's not just another false flag.

A Compound Found in Cannabis Could Make Opioids Safer

By Pat Anson, PNN Editor

What gives the cannabis sativa plant it’s pain-relieving properties?

Most people will tell you it’s cannabidiol (CBD) and/or tetrahydrocannabinol (THC), the two most well-known chemical compounds found in cannabis.  

But researchers at University of Arizona Health Sciences say terpenes -- aromatic compounds that give cannabis its distinctive “skunky” smell – have analgesic effects as well. In fact, in a new study published in the journal PAIN, they report that cannabis terpenes are just as effective as morphine in reducing neuropathic pain in laboratory animals.

“A question that we’ve been very interested in is could terpenes be used to manage chronic pain?” lead researcher John Streicher, PhD, a Pharmacology Professor at UA’s College of Medicine in Tucson, said in a press release. “What we found is that terpenes are really good at relieving a specific type of chronic pain with side effects that are low and manageable.”

Terpenes are found in all plants and are the main component of essential oils. Terpenes give lavender, sage and eucalyptus oils their distinctive smells, which are used to promote relaxation or even reduce pain and inflammation. In nature, terpenes help plants attract pollinators such as bees or to protect themselves from predators.

Most plants have only two dominant terpenes, but cannabis has up to 150 terpenes. Streicher and his colleagues tested five of the cannabis terpenes by injecting them into mice with chemotherapy-induced neuropathic pain.

They found that each of the five terpenes reduced nerve pain significantly, at levels similar to or even better than morphine. And when combined with morphine, the analgesic effects were enhanced even further.

Perhaps the most striking discovery is that the mice showed no signs of euphoria or “liking” terpenes – a sign that they may not have abuse potential.

“We looked at other aspects of the terpenes, such as: Does this cause reward? Is this going to be addictive? Is it going to make you feel awful?” Streicher said. “What we found was yes, terpenes do relieve pain, and they also have a pretty good side effect profile.”

In addition to injections, researchers also administered terpenes to the mice orally and through inhalation from a vaporizer. The results were the same. The mice had significant pain relief with no side effects or signs of addiction.

More research is needed, but some cannabis companies are already incorporating terpenes into their products. Lemon Kush, for example, is a marijuana strain that contains limonene, a terpene that smells like lemon, while the hybrid Blue Dream has a terpene that’s also found in blueberries.

“A lot of people vape or smoke terpenes as part of cannabis extracts that are available commercially in states where cannabis use is legal,” Streicher said “We were surprised to find that the inhalation route didn’t have an impact in this study, because there are a lot of at least anecdotal reports saying that you can get the effects of terpenes whether taken orally or inhaled.”

The next step for Streicher and his research team is to study whether terpenes can block the abuse potential of opioids, while at the same time enhancing their analgesic effects.

“This brings up the idea that you could have a combination therapy, an opioid with a high level of terpene, that could actually make the pain relief better while blocking the addiction potential of opioids,” Streicher said.

Experimental Non-Opioid Drug Effective in Treating Acute Pain

By Pat Anson, PNN Editor

An experimental non-opioid analgesic was effective in treating post-operative pain in two Phase 3 clinical trials, setting the stage for a New Drug Application to the FDA by Vertex Pharmaceuticals later this year.

The drug – called VX-548 – was given orally to patients with moderate-to-severe pain in the first 48 hours after an abdominoplasty or bunionectomy, two minimally invasive surgeries. VX-548 was more effective in reducing pain than the placebo, but it was not more effective than a combination of the opioid hydrocodone and acetaminophen, more commonly known as Vicodin.

In a third Phase 3 study, VX-548 was effective for up to 14 days across a broad range of surgical and non-surgical acute pain conditions. Over 80% of patients in that study rated VX-548 as good, very good, or excellent in treating pain.

“We are very pleased with the results from the VX-548 pivotal program, which demonstrate a compelling and consistent combination of efficacy and safety across multiple acute pain conditions and settings. The VX-548 benefit-risk profile ideally positions it to potentially fill the gap between medicines with good tolerability but limited efficacy and opioid medicines with therapeutic efficacy but known risks, including addictive potential,” Reshma Kewalramani, MD, CEO and President of Vertex, said in a press release.

“With FDA Breakthrough and Fast Track Designations in hand, we are working with urgency to file the New Drug Application for VX-548 and bring this non-opioid medicine to the millions of patients who suffer from acute pain each year in the U.S.”

VX-548 was generally safe and well tolerated in all three Phase 3 studies. Most of the adverse events reported by patients were mild to moderate, such as nausea and constipation.

Unlike opioids, VX-548 blocks pain in the peripheral nervous system, rather than the brain. That means it won’t have euphoric effects or be addictive. If approved for use by the FDA, experts say it would give patients and providers a much-needed alternative to opioids.

“As a physician treating patients suffering from pain for many years, I know firsthand the critical need for new, efficacious and safe treatment options,” said Jessica Oswald, MD, a Vertex consultant and Associate Physician in Emergency Medicine and Pain Medicine at University of California San Diego.

“The Phase 3 safety and efficacy across the three studies are impressive and demonstrate VX-548’s potential to change the paradigm of pain management. I look forward to the potential of having a new class of acute pain medicine — the first in more than two decades — to use as an alternative to opioids to help the millions of people impacted by acute pain.”

The risk of a surgery patient misusing opioids or becoming addicted is actually quite low – less than one percent. One recent study even found that restricting the use of opioids during surgery leads to more post-operative pain.

Vertex hopes to have VX-548 approved for a wide variety of pain conditions, not just post-operative pain.  Last month, the company released positive results for the drug in reducing pain from diabetic peripheral neuropathy.

Vertex also recently won approval from the FDA for its CRISPR gene cell therapy for sickle cell disease, which potentially offers a cure for the painful blood disorder.

Experimental Fiber Implants Block Nerve Pain with Light

By Pat Anson, PNN Editor

Researchers at the Massachusetts Institute of Technology have developed experimental fiber implants that could potentially be used to deliver pulses of light from inside the body to inhibit nerve pain. Unlike other implants, the hydrogel fibers are flexible and stretch with the body during movement.     

“Current devices used to study nerve disorders are made of stiff materials that constrain movement, so that we can’t really study spinal cord injury and recovery if pain is involved,” said co-author Siyuan Rao, PhD, now an assistant professor of biomedical engineering at the University of Massachusetts at Amherst. “Our fibers can adapt to natural motion and do their work while not limiting the motion of the subject. That can give us more precise information.”

In tests on laboratory mice with genetically modified nerves, researchers used the fiber implants to deliver blue light to the sciatic nerve, which activated the animals’ hind limb muscles.

When pulses of yellow light were used, the light inhibited neuropathic pain in the mice.

For now, MIT engineers see the fibers primarily as a research tool that can help them study the causes and potential treatments of peripheral nerve disorders in animals.

Neuropathic pain occurs when peripheral nerves are damaged, resulting in tingling, numbness and stinging sensations in the hands and feet. About 20 million Americans suffer from peripheral neuropathy, which can be caused by diabetes, chemotherapy, lupus, HIV, Lyme disease, celiac disease and many other disorders.

“Now, people have a tool to study the diseases related to the peripheral nervous system, in very dynamic, natural, and unconstrained conditions,” said co-author Xinyue Liu, PhD, who is now an assistant professor at Michigan State University. 

The MIT team’s study, recently published in the journal Nature Methods, grew out of a desire to expand the use of optogenetics -- a technique in which nerves are genetically engineered to respond to light. Exposure to specific light waves can either activate or inhibit a nerve, giving scientists a new way to study how nerves work. 

Scientists have used optogenetics in animals to trace nerves involved in a range of brain disorders, including addiction, Parkinson’s disease, and mood and sleep disorders.

Until now, optogenetics has primarily been used in the brain, an organ that lacks pain receptors, which allows for the relatively painless implantation of rigid devices. The MIT team wondered if optogenetics could be expanded to nerves outside the brain to study peripheral nerve pain.  

Because peripheral nerves undergo constant pushing and pulling from adjoining muscles and tissues, they needed more flexible devices that would not constrain movement or cause tissue damage.  

The new optical fibers are made with hydrogel — a rubbery mix of polymers and water – that is soft and flexible. The fiber has two layers; a core and an outer shell that funnel light through the fiber without escaping or scattering. 

When implanted in mice, researchers say the animals were still able to run freely on an exercise wheel. After two months, the fiber was still resistant to fatigue and could transmit light efficiently to trigger muscle contractions. 

“We are focusing on the fiber as a new neuroscience technology,” Liu says. “We hope to help dissect mechanisms underlying pain in the peripheral nervous system. With time, our technology may help identify novel mechanistic therapies for chronic pain and other debilitating conditions such as nerve degeneration or injury.”

‘I’m Still in Pain’: A Patient’s Long Wait to See a Specialist

By Molly Castle Work, KFF Health News

Teresa Johnson can’t escape the pain. It’s as if she’s getting pierced by needles all over her body, all at once. At night, she sometimes jolts out of sleep thinking bedbugs are attacking her. But it’s just the unfailing pain — day in and day out.

Johnson, 58, said her ordeal started in September 2022, when she went for a CT scan of her abdomen after a bout of covid-19. Though Johnson warned the lab she was allergic to iodine, she believes the lab tech used it in an injection, triggering an allergic reaction. She spent the next three weeks in the hospital, feeling as if her body was on fire.

When she was discharged to her home at the base of the San Jacinto Mountains in Riverside County, Johnson said, her quality of life deteriorated and her frustration mounted as she waited for her Medi-Cal plan to get her assessed by a specialist. She could barely walk or stand, she could no longer cook for herself, and sometimes she couldn’t even lift her leg high enough to step into the tub.

“I would never wish this on anybody,” Johnson said while rocking back and forth on the couch to still the pain. “You don’t know if you should cry, or just say OK, I can make it through this. It messes with you mentally.”

Johnson said her primary care doctor told her he wasn’t sure what triggered the pain but suspects it was compounded by the lingering effects of covid.

Johnson, who is diabetic, developed neuropathy, a type of nerve damage, possibly after the allergic reaction caused her blood sugar levels to skyrocket, her doctor told her.

He referred Johnson, who receives care through California’s Medicaid program for low-income people, to an endocrinologist in March.

But Johnson said she was not offered timely appointments, and it took more than six months, four referrals, multiple complaints to her health plan, and a legal aid group’s help to finally snag a phone call with an endocrinologist in mid-September.

TERESA JOHNSON

Access to specialists — from gastroenterologists to cardiologists — has been a long-standing challenge for many Medi-Cal patients, especially those in rural areas or regions facing staff shortages. The Inland Empire, where Johnson lives, has the second-lowest supply of specialists in the state, according to the California Health Care Foundation.

The state Department of Managed Health Care, which regulates most Medi-Cal health plans, requires plans to get patients in to see specialists within 15 business days, unless a longer waiting time would not harm the patient’s health. But the timeline often looks very different in reality.

“It’s hard to get a specialist to contract for Medi-Cal patients. Period,” said Amanda Simmons, executive vice president of Integrated Health Partners of Southern California, a nonprofit organization that represents community health clinics. “Specialists don’t want to do it because reimbursement rates are so low.”

Johnson said she made her first call in March to the endocrinologist assigned by her Medi-Cal insurer, Inland Empire Health Plan, and that the office offered her an appointment several months out. Over the next four months, she received three more referrals, but she said she got a similar response each time she called. When Johnson objected to the lengthy wait times, requesting earlier appointments, she was told there was no availability and that her condition wasn’t urgent.

“They told me it wasn’t important,” Johnson said. “And I asked, ‘How would you know? You’ve never seen me.’”

Esther Iverson, director of provider communications for the plan, declined to speak about Johnson’s case but said the plan makes every effort to meet the 15-day requirement. It can be challenging to meet the standard, she said, due to a lack of available physicians — especially for certain specialties, such as endocrinology and pain management.

She pointed to the nationwide physician shortage, which is more pronounced in rural areas, including parts of San Bernardino and Riverside counties, where the plan operates. She also noted that many physicians decided to leave the field or retire early due to burnout from the covid pandemic.

At the same time, she said, the plan’s enrollment ballooned to 1.6 million as eligibility expanded in recent years. Statewide, more than 15 million Californians are enrolled in Medi-Cal.

“The highest priority for us is timely access to quality care,” Iverson said.

‘I’m So Burned Out’

During her quest, Johnson enlisted the help of Inland Counties Legal Services, which provides free legal representation to low-income residents. They called the plan multiple times to request earlier appointments but got mired in bureaucratic delays and waiting periods.

In one instance in August, after the insurer told Johnson it couldn’t meet the 15-day time frame, her legal representative, Mariane Gantino, filed an appeal, arguing that Johnson’s request was urgent. The insurer’s medical director responded within a few hours denying the claim, saying the plan concluded that her case was not urgent and that a delay would not cause a serious threat to her health.

“I’m so burned out after dealing with this for so long,” Johnson said in mid-September. “Why do they have the 15-day law if there aren’t going to be any consequences?”

A few days later, Johnson finally received the call she had been waiting for: an offer of a phone appointment with an endocrinologist, on Sept. 18. During the appointment, the doctor adjusted her diabetes and other medications but didn’t directly address her pain, she said.

“I’m in the same position,” Johnson said. “I’m still in pain. What’s next?”

Over the years, Johnson has worked a variety of jobs — from driving eighteen-wheelers cross-country to weaving hair — but her most consistent work was as a caregiver, including to her six children, 21 grandchildren, and three great-grandkids, with another great-grandchild on the way. Now, because of her extreme pain, the roles have been reversed. A daughter and granddaughter who live with her have become her full-time caregivers.

“I can’t do nothing. I can’t take care of my grandkids like I used to,” said Johnson, who sleeps most of the day and wakes up only when her pain medication wears off. “I was planning to take care of the new baby that’s coming. I probably can’t even hold her now.”

Pain Patients Get ‘Substantial Relief’ from Scrambler Therapy

By Pat Anson, PNN Editor

A little-known therapy for Complex Regional Pain Syndrome (CRPS) and other painful neuropathic conditions is finally getting some attention from a prominent medical journal.

“Scrambler therapy is the most exciting development I have seen in years — it’s effective, it’s noninvasive, it reduces opioid use substantially and it can be permanent,´ says Thomas Smith, MD, a professor of oncology at the Johns Hopkins University School of Medicine and co-author of a review recently published in The New England Journal of Medicine.

Scrambler therapy – also known as Calmare pain therapy -- sends mild electric signals through the skin via electrodes placed near areas where chronic nerve pain is felt. Similar to transcutaneous electrical nerve stimulation (TENS), the idea is to “scramble” pain signals being sent to the brain and reduce central sensitization.

Some patients get immediate relief after a 30-minute scrambler session, but most will have to undergo a series of treatments on successive days to have a prolonged analgesic effect. Smith says many patients “get really substantial relief.”

“The duration of relief usually increases with each day of treatment, and in contrast to TENS, analgesic effects have been reported to last for weeks, months, or even years after a treatment course,” wrote Smith, who reviewed 381 clinical trials of TENS and scrambler therapy with his co-author.

“The major limitation with respect to our understanding of electroanalgesia is the small number of well-designed, large, randomized, sham-controlled clinical trials of TENS and scrambler therapy.”

In one small study, patients getting scrambler therapy had a 91% reduction in pain and reduced their use of opioids and other pain relievers by 75 percent.

“If you can block the ascending pain impulses and enhance the inhibitory system, you can potentially reset the brain so it doesn’t feel chronic pain nearly as badly,” Smith says. “It’s like pressing Control-Alt-Delete about a billion times.”

Scrambler therapy seems to be most effective in patients with CRPS or those who develop neuropathic pain after chemotherapy. It’s also been used to treat fibromyalgia, shingles, diabetic neuropathy and post-operative pain.

Amanda Greening was bedridden by CRPS at the young age of 20, but was able to walk again after several sessions of scrambler therapy. Amanda’s father wrote a column for PNN on her recovery. So did a local TV station:

Although scrambler therapy was approved by the FDA in 2009 for patients with chronic or neuropathic pain, the procedure is still not widely available or covered by insurance. Only one company makes the scrambler device, which costs about $65,000, and practitioners have to undergo several days of training to use it. Treatments cost about $300 per session.

Like other pain treatments, scrambler therapy doesn’t work for everyone. About 10 to 20% of  patients have no analgesic response -- a risk many would be willing to take, if it means freeing themselves from a lifetime of pain.

‘Promising Results’ for Low-Dose Naltrexone as Pain Reliever

By Pat Anson, PNN Editor

Low-dose naltrexone (LDN) continues to get more recognition from the medical community as a treatment for some types of chronic pain.

In a review of 47 studies on the off-label use of LDN, researchers at the University of Kansas Medical Center found “promising results” that naltrexone improves pain and function and reduces symptom severity in patients with chronic inflammatory or centralized pain. Most of the studies were small, however, and larger clinical trials are needed to demonstrate LDN’s efficacy.

“Though the results look promising, further, more well controlled studies are required before formal recommendations can be made,” said lead author Adam Rupp, DO, who will present his findings this week at the annual meeting of the American Society of Regional Anesthesia and Pain Medicine (ASRA) in Orlando, Florida.

Naltrexone is an inexpensive generic drug that is only approved by the Food and Drug Administration as a treatment for substance abuse. In 50mg doses, naltrexone blocks opioid receptors in the brain and decreases the desire to take opiates or alcohol.  

But in smaller doses of 5mg or less, patients with fibromyalgia, interstitial cystitis, intractable pain and other chronic conditions have found LDN to be an effective pain reliever. But because LDN is prescribed “off label” for pain, much of the evidence supporting LDN is anecdotal.

How naltrexone works is not entirely clear, but LDN supporters believe the drug helps modulate the immune system, reducing inflammation and stimulating the production of endorphins, the body's natural painkiller. LDN is not recommended for people currently taking opioid medication because it blocks opioid receptors and may cause withdrawal.

In their literature review, Rupp and his colleagues found that LDN improved physical function, sleep, mood, fatigue and quality of life in patients with Complex Regional Pain Syndrome (CRPS), fibromyalgia, diabetic neuropathy, Crohn’s disease, rheumatoid arthritis and low back pain. In patients with Crohn’s, improvements were also noted in the colon’s appearance during colonoscopies.

Side effects from LDN were minimal, consisting most commonly of vivid dreams, headaches, diarrhea and nausea. Most of the side effects resolved with continued use of LDN.

“The evidence in this review provides support for the off-label use of LDN for various chronic
inflammatory or centralized pain conditions. However, it is apparent that high-quality controlled studies focusing on administration, dosing and follow up time are needed before formal recommendations can be made,” Rupp said.

“Despite the current paucity of high-quality evidence in the literature, LDN continues to offer promising results in the management of symptoms in patients with chronic inflammatory or centralized pain conditions.”

Because LDN is not recommended as a pain treatment by the FDA or professional medical societies, patients interested in trying it often encounter doctors who refuse to prescribe it or don’t know anything about it. The LDN Research Trust includes a list of LDN-friendly doctors and pharmacies on its website.

Cross-Country Bike Ride Raising Awareness About Peripheral Neuropathy

By Madora Pennington, PNN Columnist

Gregory Maassen, a 55-year-old with debilitating peripheral neuropathy, sits in a tent in Ely, Nevada charging his e-bike, drone and cameras. He has been e-biking from Washington DC to San Francisco to raise funds for The Foundation for Peripheral Neuropathy, collecting video for a documentary along the way.

When Maassen was at his most ill, a 3,400-mile solo bike trek would have been only a fantasy. But he dreamed of such things when he was bedbound. Hope, he believes, is a key to improving.

Maassen had been a successful international businessman, until his life changed in 2018 when he found himself covered with tics while working in South Africa. He became sick with flu-like symptoms and later a burning sensation all over his body.

Finding no cause or cure, doctors told Maassen his physical symptoms were from stress and to get psychiatric help. Arguing with them was useless. 

“If you are diagnosed as psychosomatic, you don’t get the right care and treatment,” said Maassen, who was unable to work, slept 18 hours per day and sank into a deep depression.

Eventually, doctors at Johns Hopkins Hospital in Maryland took tissue samples from the skin on his legs. They could see the nerve damage that was causing the consuming, burning pain. Once diagnosed correctly with post-infectious small fiber neuropathy, Maassen was started on medications that helped.

Damaged Nerves

According to the National Institutes of Health, there are more than 100 kinds of peripheral neuropathy, a type of nerve damage. Peripheral neuropathy affects 20 million Americans, but some believe that estimate is low because many patients are misdiagnosed or not tested for neuropathy at all.

Nerves are the network cables of the body, allowing the body to communicate with itself. Some nerves control physical movements, others sense input such as light, touch, temperature and pain, and some regulate automatic processes like breathing and digestion. Damaged nerves transfer incorrect signals or may interrupt them altogether.

Physical injury, infection, auto-immune disease, cancer, and diabetes are some common causes of peripheral neuropathy. Treatment varies depending on where the damage is and the symptoms. Exercise is often recommended because the increased blood flow nourishes nerves and strengthens muscles. 

When Maassen’s doctors recommended exercise, he tried returning to his passion for hiking, but it proved too strenuous. Not being able to hike added to his depression.

Cycling at the time seemed impossible because the area around him was too hilly. He tried swimming, but the chlorine aggravated his symptoms. He was so weak he could not finish even beginner lessons of Pilates he found on YouTube.

Because he is Dutch by birth, cycling is part of Maassen’s culture. It was never a passion of his, just what many people in his native country do. Maassen turned to an electric bike, or e-bike.

Rather than relying solely on the rider’s strength, an e-bike has a small motor that boosts the rider’s pedaling power. Hills and distances can be manageable, even for a debilitated person.

At that time, there was little Maassen could physically do for himself. His wife provided what he describes as “a marathon of support.” But it was also a lonely time for him, as it is for many with chronic illness.

“When you are endlessly sick, you lose your support,” Maassen says. “People don’t want to listen to you. Only your closest friends will continue to reach out.”

Maassen’s e-biking gave him small adventures that restored his fitness, and eased his depression and loneliness. Running an errand or visiting a friend made his brain active and happy by registering something positive. Later, he began kayaking. Very slowly, he rebuilt his strength. Within a few months, Maassen was able to go on long rides. He resumed working the next year and started an e-bike club.

To raise awareness for peripheral neuropathy and encourage the sport of e-biking for all, Maassen embarked on his e-bike journey along the Lincoln Highway on April 2nd of this year. So far, he has raised over $120,000. He has another dream: to establish this route as a new transcontinental cycling route for e-bikers. Unlike cyclists, e-bikers need electricity to re-charge their bikes.

Maassen is an FAA-certified drone pilot. He is using his drone to film, sometimes as he rides. He does interviews on stops and rest days and gets more footage for future documentaries about e-biking and this route.

Maassen still has bad days where he suffers burning pains “like crazy,” but he forces himself to do things and not focus on the pain. While on this journey he makes a conscious effort to fully engage in the moment, relishing the beautiful scenery and the warm people he meets. He stays in campgrounds or cheap hotels to keep the costs of the trip low. His favorite meal is a spicy Italian Subway sandwich.

Maassen recently became a U.S. citizen, but he travels with a souvenir from his home country – Dutch wooden shoes, which helps to start conversations. He still feels sorrow at the horrible period before he was correctly diagnosed. He hopes his ride will contribute to education and awareness.

“Maybe people will recognize the tingling, burning, the sinking into depression. I hope they will go to the Foundation’s website or maybe see a neurologist,” he told me. “With proper support from the medical profession, understanding your limitations, and making lifestyle changes you can make a difference in your life.”

Gabapentinoids and Anti-Depressants Recommended for Diabetic Neuropathy

By Pat Anson, PNN Editor

People with painful diabetic neuropathy (PDN) should be treated with gabapentinoids, anti-depressants and sodium channel blockers, according to updated guidelines from the American Academy of Neurology (AAN). The guidelines also recommend some alternative treatments, such as ginkgo biloba, capsaicin patches and cognitive behavioral therapy, but strongly discourage the use of opioids.

The AAN’s new guidelines, published online in the journal Neurology, acknowledge that many of the recommended therapies for PDN don’t directly treat physical pain, but they improve mood and sleep, and that helps reduce “pain perception.”

“In treating patients with PDN, it is important to assess other factors that may also affect pain perception and quality of life. Patients with diabetes are more likely to have mood disorders (most commonly, major depression) and sleep disorders (especially obstructive sleep apnea) than the general population,” an AAN panel of experts found. “Therefore, treating concurrent mood and sleep disorders may help reduce pain and improve quality of life, apart from any direct treatment of the painful neuropathy.”

Nearly 26 million Americans have diabetes and about half have some form of neuropathy, according to the American Diabetes Association. PDN causes nerves to send out abnormal signals, causing patients to feel stinging or burning pain, as well as loss of feeling in their toes, feet, legs, hands and arms. More severe cases can result in ulcers or amputation of the affected limbs.

The last update to the AAN guideline was in 2011, when opioids such as morphine and oxycodone were said to be “probably effective and should be considered.” Much has changed over the last decade, and the AAN no longer supports their use for PDN.

"Current evidence suggests that the risks of the use of opioids for painful diabetic neuropathy therapy outweigh the benefits, so they should not be prescribed," said lead author Brian Callaghan, MD, an associate professor of neurology at University of Michigan Health.

‘Probably’ Better Than Placebo

The only oral medications the AAN now recommends for PDN are gabapentinoids (pregabalin and gabapentin); serotonin-norepinephrine reuptake inhibitors (SNRIs) such as duloxetine; tricyclic anti-depressants such as amitriptyline; and sodium channel blockers such as valproic acid, which are usually used to treat seizures. An SNRI can also be combined with a weak opioid like tramadol for PDN.

There are caveats to all of these drugs since the evidence for them is limited and they were originally developed for other conditions such as depression or epilepsy. For example, the guidelines state gabapentin is “probably more likely than placebo to improve pain” and pregabalin is “possibly more likely” to help with PDN.

Topical medications such as capsaicin and buprenorphine patches also get the lukewarm endorsement of “possibly” being better than a placebo.

When one class of medication doesn’t work for PDN, experts say patients should try another.

“Managing expectations is also important,” Callaghan said. “Our second recommendation urges the provider to be frank with patients that the goal is to reduce their pain. It may not be possible to completely resolve the symptoms.”

A 2017 study by the Agency for Healthcare Research and Quality found that duloxetine (Cymbalta) and some other anti-depressants are moderately effective at relieving PDN, but found little or no evidence that opioids and gabapentinoids are helpful in treating neuropathic pain.

Researchers say a significant limitation for all pain relievers – not just opioids – is that few studies examine their safety and efficacy longer than three months. PDN is a progressive disorder that is likely to last a lifetime.  

“Given the chronicity of pain in those with diabetic neuropathy and the potential for evolving side effects, long-term studies are needed to better inform the long-term pain management in this population. Specifically, future studies should focus on the long-term effects (positive and negative) of opioids in this population to determine whether there is any role for these medications in this population,” the AAN’s expert panel concluded.

My Cancer Is Back: Facing Surgery With CRPS

By Cynthia Toussaint, PNN Columnist

After hearing the worst words of my life, “Your cancer has grown back,” I felt hopeless and hated the world. Worse, I had to tell my longtime partner and caregiver, John, the grim news. How could we pull up our frayed boot straps again and survive yet another impossible health crisis?

Since getting Complex Regional Pain Syndrome (CRPS) four decades ago, people often use words like “fighter,” “pain warrior” and “super human” to describe me. The most recent catch phrase is, “Cynth, you got this!”

I’ve come to detest this perceived awesomeness. I don’t want to be an uber-person. I never did. I’m tired. I’m so, so tired. And I long for a slice of vanilla-flavored normal.

As the owner of CRPS and 19 comorbidities, I could not afford the diagnosis of triple negative breast cancer, the most aggressive form. But that’s what was delivered, since luck has never been this lady’s lot.

Without consulting me, the universe long ago decided that I’m supposed to slay every dragon while surviving never ending illness and trauma. This latest hell-news has filled me with anger, rage and major depression.

So much so, that for the first time ever, I’m isolating. This social butterfly has returned to her cocoon, unable to feel joy.

I can’t sleep as I’m plagued by night terrors. Each afternoon, my body trembles uncontrollably. Once heavenly activities, like meditation, exercising and eating, are now chores.

John massages my taut muscle tension through the days and nights – and my IBS has gone haywire. My bubbly spirit is absent and what’s left is demoralized.

And not so long ago, I thought I had this thing licked.

Early last year, after six months of weighing my impossible-with-CRPS treatment options, I started aggressive chemotherapy knowing that this regimen could leave me with a life not worth living. The dream was that my pain would stay in check and I’d achieve a Clinical Complete Response (cancer that cannot be seen with imaging). I’m certain chemotherapy almost ended me, as I was left with virtually no immune system. As a bonus, this was during COVID. 

I was coined a “super responder” when I miraculously accomplished a complete response. At that point, the odds were strongly in my favor that the cancer was gone. But the only way to be sure was to do the follow-up standard of care surgery, which I chose to forego because, with CRPS, surgery is, well, not an option.

The doctors were floored by how well I did, and every indicator leaned toward a clean pathology report. I was ready to move on with my life, one that I felt I’d earned by doing everything right (diet, exercise, stress management, good sleep – the whole kit and caboodle!) One doctor commented, “Don’t even look at the survival numbers. They don’t apply to you anymore.”   

True to form, things went as far south as possible. Because I’m one of the unlucky ones who’s cancer stem cells never went away, my malignancy is growing back. This is not a “recurrence,” but a “persistence” because the chemo didn’t hold.

And now that my complete response is gone, I’ll never have my prior odds. John has lamented for years, “You NEVER get a break!” and I’m finally seeing it his way.

For a chance of survival, I must now have – ta daaa!! – surgery. The doctors tell me my best shot is to do a lumpectomy with follow-up radiation or a stand-alone mastectomy.

Tragically, radiation is off the table as it often causes neuropathic pain. In fact, a radiologist who I respect told me flat out, “I can’t ethically do it to you.” And during a recent visit with my surgeon, she strongly advised that, due to CRPS, I’m not a candidate for a mastectomy, let alone reconstructive surgery. Wow.

Finding a New Care Team

Adding insult to injury, out of nowhere, my lead oncologist dropped me! She did so due to questionable guidance (something I can’t detail here) and is fearful of litigation, which doesn’t make it hurt less. This woman had become my hero and I trusted her with my heart and life. Her betrayal has been soul-crushing and created a crisis of faith. I don’t know who or what to believe in anymore.

But through the shadows, I’m quietly planning my next move – and will take on Round Two one slow... step… at… a... time. I’m assembling a new-and-improved care team to up my odds, including an oncologist, acupuncturist, physical therapist, pain specialist and psychologist. I’ve sweetened the pot with an EMDR (an effective technique for trauma release) practitioner who specializes in people with CRPS. Heck, I’ve even lined up the use of a heated pool in these COVID shutdown days.    

I’m going to have a lumpectomy, a word I can still barely say, let alone write. The scariest part is that my surgeon will also remove a possibly involved lymph node in a nerve rich area, ripe for ample, new pain. My new oncologist is concerned that due to a surgery-induced CRPS flare, my arm may freeze up and become a non-functional torture machine.

Even if the surgery mercifully works without condemning me back to bed, this wouldn’t flip me a “get-out-of-jail-free” card. Because I can only do the “minor” surgery without radiation, my odds of a quick recurrence remain high. This means I’ll be on the prowl for some off-the-grid insurance, perhaps low-dose chemo or an immunotherapy clinical trial. But neither can measure up to the standard of care radiation.

God, to be well enough to be sick!         

So, here I am again, looking down the barrel of a gun, knowing it likely has a bullet with my name on it. Like I said, I’m tired and angry. I’m up to my ass with picking the lesser of two evils, and having to crack the code of the near impossible.

Give me a break, already! And I don’t mean this in a small way. I’m shouting out to the big, bad, ice cold universe that I hope, somewhere, somehow, has a heart.

Topical Gel Shows Promise as Treatment for Neuropathic Pain

By Pat Anson, PNN Editor

An experimental gel developed to prevent skin damage caused by aging and ultraviolet light is showing promise as a treatment for chronic neuropathic pain, according to research underway in Australia.

The topical gel – known as RM191A – contains a copper-based compound that is absorbed by the skin and prevents the buildup of free radicals that cause skin damage associated with aging and skin cancer.

In a study recently published in the journal Redox Biology, RM191A was found to have potent antioxidant, anti-inflammatory and wound-healing properties in laboratory mice.

The gel is currently being evaluated in 24 patients at a Sydney hospital as a treatment for chronic nerve pain caused by surgery, chemotherapy, trauma and diabetes.  Results are expected later this month.

“Early sample uses of this topical formulation indicated it could be a significant in the management of certain types of chronic nerve pain,” says Llewellyn Casbolt, chief scientist and co-founder of Sydney-based RR MedSciences, which is developing the gel.

“In many ways, scientists see our discovery as a new class of anti-inflammatory that acts by the modulation of free radicals as well as reducing several inflammatory cytokines, providing a drug that can be therapeutically useful where the reduction of inflammation, as well as cellular and tissue healing - indeed pain relief - is also advantageous for a patient.”

The company plans to release an over-the-counter version of its gel in the next 12-18 months as a treatment for skin damage. It will take longer to get regulatory approval for the gel as a treatment for nerve pain and may require a prescription.

RR MedSciences (RRMS) plans to conduct further trials and is seeking additional partners and funding to accelerate the gel’s development.

“The management of pain, often related to conditions of inflammation or trauma that results in nerve or chronic pain is an area of great need.  Advancing the ability for people to modulate their pain, in a safe and effective manner that improves quality of life, is a core objective,” said Helena Libershal Casbolt, CEO and co-founder of RRMS.

A subsidiary of RRMS is currently selling a copper-based body cream called Blue Healer Care as a treatment for damaged skin and for relief from skin irritation and muscle soreness.

Study Finds Most Drugs Ineffective for Neuropathic Pain

By Pat Anson, PNN Editor

A first of its kind study that compared four medications widely used to treat neuropathy found that all four were usually ineffective in treating pain and many patients stopped taking them due to side effects.    

Over 20 million people in the U.S. suffer from neuropathic pain, a tingling, burning or stinging sensation in the hands and feet caused by nerve damage. Neuropathy is often caused by diabetes, chemotherapy or trauma, but in about 25% of cases the cause is unknown and classified as cryptogenic sensory polyneuropathy (CSPN).

There is little guidance for physicians and patients on what drugs to take for CSPN, so researchers at the University of Missouri School of Medicine conducted a “real world” study in which 402 patients with CSPN took one of the four neuropathy medications.

The four drugs studied were nortriptyline (Aventyl), a tricyclic antidepressant; duloxetine (Cymbalta), a serotonin-norepinephrine reuptake inhibitor (SNRI) antidepressant; pregabalin (Lyrica), an anti-seizure drug; and mexiletine (Mexitil), an anti-arrhythmic medication used to treat irregular heartbeats.

Nortriptyline, duloxetine and pregabalin are approved by the FDA for treating neuropathy, while mexiletine is used off-label. None of the drugs were originally developed to treat neuropathic pain.

"As the first study of its kind, we compared these four drugs in a real-life setting to provide physicians with a body of evidence to support the effective management of peripheral neuropathy and to support the need for newer and more effective drugs for neuropathic pain," said lead researcher Richard Barohn, MD, executive vice chancellor for health affairs at the University of Missouri.

After 12 weeks of use, any drug that reduced pain for a patient by at least a 50% was considered effective, a recognized industry standard to define therapy success.. Researchers also kept track of patients who stopped taking a drug and dropped out of the study due to adverse effects.

The study findings, published in JAMA Neurology, can best be described as underwhelming. Patients were far more likely to stop taking a drug than they were to stay on a medication that was helping them.    

Of the four drugs, only nortriptyline was an effective pain reliever for at least 25% of patients. It also had the second-lowest drop-out rate (38%), giving it the highest level of overall utility. Duloxetine had the second-highest efficacy rate (23%) and the lowest drop-out rate (37%).

Pregbalin had the lowest efficacy rate (15%) and the second highest drop-out rate (42%), while mexiletine had the highest drop-out rate (58%) and an efficacy rate of 20 percent.

EFFICACY RATE OF NEUROPATHY DRUGS

"There was no clearly superior performing drug in the study," Barohn said. "However, of the four medications, nortriptyline and duloxetine performed better when efficacy and dropouts were both considered. Therefore, we recommend that either nortriptyline or duloxetine be considered before the other medications we tested."

While nortriptyline had the highest efficacy rate, it also had the highest rate of adverse events, with over half of patients (56%) reporting side effects such as dry mouth, drowsiness, fatigue and bloating.  

Previous studies have found that duloxetine and pregabalin had higher efficacy rates for neuropathic pain, but Barohn and his colleagues say their research more accurately reflects what patients experience in real life and what physicians encounter in their practice.

“Our findings could affect how these 4 drugs are used by all physicians who treat patients with neuropathy. Findings support duloxetine and nortriptyline as better-performing drug choices in this population with neuropathic pain, suggesting that they should be prescribed before pregabalin or mexiletine are considered. However, this study also supports a finding that all 4 drugs helped improve pain in at least some patients, so each could be tried if others failed,” they concluded.     

There are several other drugs used to treat neuropathy, including gabapentin, venlafaxine and sodium channel inhibitors. Barohn says additional comparative studies should be performed on those drugs. His goal is to build effectiveness data on nearly a dozen drugs for CSPN.

Study Finds Microdosing THC Reduces Pain Levels

By Pat Anson, PNN Editor

Very low doses of inhaled THC – the psychoactive ingredient in cannabis – can significantly reduce pain levels in chronic pain patients, according to a small study conducted in Israel.

The concept of “microdosing” cannabis isn’t new, but this was the first clinical study to demonstrate its effectiveness in temporarily relieving pain. The study was sponsored by Syqe Medical, an Israeli medical technology company that makes an inhaler designed to deliver microdoses of cannabis and other drugs.

The study involved 27 patients living with neuropathy, radiculopathy, phantom limb pain or Complex Regional Pain Syndrome (CRPS), who self-reported pain levels of at least 6 on a zero to 10 pain scale. Participants were randomly assigned to three groups that inhaled either a placebo or two different microdoses of THC.  

The most effective dose to relieve pain was just 500 micrograms of THC, inhaled 3-4 times per day. Participants reported a 2 to 3 point reduction in their pain levels for 150 minutes.  

A typical cannabis patient might consume 150,000 micrograms of THC per day – about 75 times more than the highest dose used in the study. Researchers say their findings, published in the European Journal of Pain, suggest that pain patients can benefit from dramatically lower doses.

"We can conclude from the study results that low doses of cannabis may provide desirable effects while avoiding cognitive debilitations, significantly contributing to daily functioning, quality of life, and safety of the patient,” said lead researcher Elon Eisenberg, PhD, Director of the Multidisciplinary Pain Relief Unit at Rambam Health Care Campus in northern Israel.

“The doses given in this study, being so low, mandate very high precision in the treatment modality. This precision is unique to the Syqe drug delivery technology, enabling cannabis dosing at pharmaceutical standards."

There were side effects from inhaling microdoses of THC. About 20% of patients reported feeling “high” or experienced dizziness, sleepiness, nausea, cough or dry mouth. But researchers said there was “no evidence of consistent impairment” in any of the participants.

The risk of impairment from THC is one reason researchers and cannabis companies have largely focused on the medical benefits of cannabidiol (CBD), a compound also found in marijuana. CBD is not psychoactive, while THC can make people impaired – at least in high doses.

"This study is the first to show that human sensitivity to THC is significantly greater than previously assumed, indicating that if we can treat patients with much higher precision, lower quantities of drug will be needed, resulting in fewer side effects and an overall more effective treatment,” said Perry Davidson, CEO of Syqe Medical.

“The Syqe drug delivery technology is also applicable to opioids and other compounds that, while potentially effective, are notoriously associated with dangerous side effects. The introduction of a tool to prescribe medications at such low doses with such high resolution may allow us to achieve treatment outcomes that previously were not possible."

In addition to cannabis, the company is also exploring the use of its inhaler to deliver other drugs for treating pain, sleep, anxiety and cancer. The Syqe inhaler is sold in Israel by Teva Pharmaceuticals. Approval is also being sought to begin sales in Europe, Canada and Australia. Syqe is planning to submit a medical device application to the Food and Drug Administration in the United States.

Experimental Treatment Targets Neuropathic Pain

By Pat Anson, PNN Editor

Researchers in Denmark have developed a promising new compound to treat neuropathy that targets the hyper-sensitized nerves that cause chronic pain. The experimental compound – a peptide called Tat-P4-(C5)2 -- has only been tested in mice, but researchers hope to begin clinical trials on humans soon.

"We have developed a new way to treat chronic pain. It is a targeted treatment. That is, it does not affect the general neuronal signaling, but only affects the nerve changes that are caused by the disease," says Kenneth Lindegaard Madsen, PhD, Associate Professor at the University of Copenhagen.

"We have been working on this for more than ten years. We have taken the process all the way from understanding the biology, inventing and designing the compound to describing how it works in animals, affects their behaviour and removes the pain.”

Madsen and his colleagues recently published their findings in the journal EMBO Molecular Medicine .

The image below shows the compound Tat-P4-(C5)2 after it is injected into the spinal cord. The compound (purple) penetrates the nerve cells of the spinal cord (yellow), but not the surrounding cells (the cell nuclei are blue). The compound blocks neuropathic pain signals – the kind associated with diabetic neuropathy, shingles, phantom limb pain and chemotherapy-induced pain — from being sent to the brain.

UNIVERSITY OF COPENHAGEN

In a previous study, the researchers showed in an animal model that use of the compound can also reduce tolerance and the risk of addiction. They believe the compound will be more effective and safer than the anti‐convulsants, antidepressants and opioid medications now used to treat neuropathy.

"The compound works very efficiently, and we do not see any side effects. We can administer this peptide and obtain complete pain relief in the mouse model we have used, without the lethargic effect that characterises existing pain-relieving drugs," said Madsen.

"Now, our next step is to work towards testing the treatment on people. The goal, for us, is to develop a drug, therefore the plan is to establish a biotech company as soon as possible so we can focus on this."

What You Should Know About Neuropathy

By Barby Ingle, PNN Columnist

November is Nerve Pain Awareness Month. Or as we like to call it at iPain, “NERVEmber.”

There are dozens of chronic conditions that involve nerve pain. Neuropathy is a collection of disorders that occur when nerves of the peripheral nervous system are injured or damaged. The peripheral nerves are the ones outside of the brain and spinal cord — in our arms, legs, hands and throughout the body.

There are 3 types of peripheral nerves:  

• Autonomic nerves regulate biological activities that people do not control consciously such as breathing, digesting food and heartbeat. 

• Motor nerves control movements of muscles under conscious control such as walking, grasping things and talking.

• Sensory nerves transmit information about sensory experiences such as feeling a light touch or the pain resulting from a cut.

Some neuropathies affect all three types of nerves, others affect one or two types. Some of the diagnostic terms you might hear are predominately motor neuropathy, predominately sensory neuropathy, sensory-motor neuropathy and autonomic neuropathy.  

Neuropathy often causes pain, tingling or numbness in the hands and feet. Healthcare professionals had a longstanding belief that neuropathy pain is just a symptom of an illness and therefore not a disease. 

We now know that chronic nerve pain is a disease in itself, and the medical community and public are beginning to look at it in this way.

There are approximately 150 known types of neuropathy and the causes of many are not yet known.

Thirty percent of neuropathies are caused by diabetes, 30% are idiopathic or of an unknown cause, and the other 40% are attributed to autoimmune disorders, tumors, genetic, infections, environmental toxins and nutritional imbalances.

A great resource for patients is Dr. Norman Latov’s book, “Peripheral Neuropathy: When the Numbness, Weakness, and Pain Won't Stop.” This book helps us understand the causes of neuropathies in greater detail.

We need to increase awareness, conduct research, provide better clinical training, and better tools for diagnosing and treating neuropathy. Funding for neuropathy research is difficult to obtain because clinical professionals do not fully understand all of the complexities of neuropathy diseases and conditions. Far too often, if a patient does not have a known neuropathic condition, providers will say they could not possibly have a neuropathy.

Nerve Pain Is Not Just a Symptom

But neuropathy is not just a symptom of another disease, it can be a disease in itself.  When medical professionals fail to recognize the disease or causes of neuropathy, it leads to misdiagnosis, failure to diagnose, and delays in getting proper treatment. This can cause further damage to the patient.  

I have had some doctors tell me that neuropathy does not affect the upper body, hands or face, so I could not possibly have neuropathy and it must be something else going on. Know your limitations and your healthcare providers’ limitations. Sometimes it is difficult for them to understand all of our symptoms or the daily problems we face living with neuropathy.

It is important that we increase our communication skills as patients and caregivers. Better communication allows for better care and better answers. Too often our healthcare professionals stop short of proper diagnostic procedures due to assumptions, poor attitudes, and limited treatment options available to them. They also get pressure from insurance companies that limit payments for treatment and testing. Some providers also fail to understand the potential serious impact of these conditions going undiagnosed and undertreated.  

There are times when a doctor might believe that you can do something that you know will increase your symptoms or set off a flare. Communicate these limitations to your doctor and find out their knowledge of your condition.

Here are 5 tips to better access to proper and timely care.  

1. Seek credible information, keep your mind open to new treatments and provide copies of your research to your doctor when necessary. Remember – our providers see many patients day after day and do not always have the time to do research. You may be the first one to bring new information to them.

2. With better treatment options, we will be less frustrated as patients and can make greater progress in our goal to improve daily living.

3. Use a multidisciplinary approach to treatment. Include on your team of providers doctors who specialize in pain management, internal medicine, neuromuscular neurologists, physical therapists and psychologists/psychiatrists. Depending on the type of neuropathy you have, you may want to add doctors of immunology, radiology, oncology, hematology (liver), cardiology, pulmonology, orthopedics, urology, gastroenterology, podiatry, or other medical disciplines. 

4. When you read books by other patients or hear of new treatments in your social circles, be sure to have your own treating provider consult on those ideas. Patients are not one-size-fits-all. What works for someone else may not work for you.

5. Work with a healthcare provider who works with neuropathy patients on a regular basis. They tend to be more familiar with the daily challenges we face as patients.

Until research provides better answers and tools for diagnosing neuropathy, good doctor-patient communication is essential to diagnose and treat neuropathy in a timely manner.
