Survey Finds Patients and Doctors Unsatisfied with Treatments for Acute Pain

By Pat Anson

Nine out of ten (89%) patients who recently had short-term acute pain say it caused a major disruption in their lives, limiting their ability to sleep, exercise and enjoy leisure activity, according to a new survey. Many patients also expressed dissatisfaction with the pain medication they received and want to try a new one if their pain returns.

The survey was conducted by Vertex Pharmaceuticals, which is awaiting FDA approval of suzetrigine, its experimental non-opioid medication for acute pain. Vertex surveyed 1,001 adults and 547 doctors who were treated for or who treated acute pain. The company also commissioned a survey by the American Academy of Orthopaedic Surgeons (AAOS), which asked similar questions of 49 of its members who treated patients with moderate-to-severe pain from surgery.

The resulting report, “The State of Pain in America,” is obviously intended to drum up support for suzetrigine by showcasing dissatisfaction with current treatment options for acute pain. But the surveys also provide some interesting insights into what patients and doctors think about opioids and pain care in general.

“The Vertex and AAOS surveys underscore that treating acute pain in today’s health care landscape can be complex, as are the complexities that patients and health care providers have when personalizing pain management, highlighting the unmet need in this therapeutic area for more options,” Vertex said.

About 80 million adults receive treatment for acute pain in the U.S. each year, about half of whom receive an opioid, according to Vertex. Many also take acetaminophen or nonsteroidal anti-inflammatory drugs (NSAIDs) for pain relief.

Nearly a third of patients (31%) said they stopped taking analgesics before their acute pain resolved and 77% said they would be interested in trying a different medication – clear indications of dissatisfaction with their pain care.

Patients were also concerned with how acute pain impacted their lives:

• 70% Limited their ability to walk and exercise

• 69% Limited their sleep

• 65% Limited their hobby or leisure activity

• 65% Made them feel irritable or emotionally drained

• Missed an average of 19 work days annually

The surveys also found that both patients and doctors were worried about the risk of opioid addiction:

• 49% of patients concerned about opioid addiction

• 78% of doctors concerned about patients becoming addicted to opioids

• 88% of doctors believe patients prefer to manage pain without opioids

• 67% of patients said they would request a non-opioid medication in the future

• 52% of patients want a pain medication with fewer side effects

In addition, 83% of providers and 74% of AAOS surgeons said there was a high need for a new class of non-opioid pain medication.

Whether suzetrigine is a solution to these issues is an open question. Unlike opioids, which act on pain receptors in the brain, suzetrigine is designed to block pain in the peripheral nervous system. That means it won’t have the same “liking” effects of opioids or be addictive.

But in clinical studies, suzetrigine was not more effective than a low dose of Vicodin in treating acute pain in patients recovering from minimally invasive surgeries.

The risk of a surgery patient misusing opioids or becoming addicted is actually quite low – less than one percent. One study even found that patients who received no opioids during surgery were more likely to have post-operative pain and require opioids during recovery.

Vertex hopes suzetrigine will be approved by the FDA in January for post-operative acute pain.  The company is also studying the drug as a treatment for pain caused by diabetic peripheral neuropathy and for lumbosacral radiculopathy.  

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.

New Non-Opioid Analgesic Gets Priority Review from FDA

By Pat Anson

The Food and Drug Administration could approve an experimental non-opioid analgesic early next year, potentially making it the first new medication for acute pain in over two decades.

Vertex Pharmaceuticals says the FDA has accepted its New Drug Application for suzetrigine, giving the drug a priority review with a target action date of January 30, 2025. Suzetrigine has previously been granted FDA Fast Track and Breakthrough Therapy designations for the treatment of moderate-to-severe acute pain.

“Today’s FDA filing acceptance for suzetrigine marks a critical milestone toward bringing this new, transformative non-opioid analgesic to the millions of patients,” Nia Tatsis, PhD, an Executive Vice President and Chief Regulatory and Quality Officer for Vertex, said in a statement.

“The FDA’s granting of a priority review further reinforces the high unmet need in treating acute pain, and the filing brings us one step closer to our objective of filling the gap between medicines with good tolerability but limited efficacy and opioid medicines with therapeutic efficacy but known risks, including addictive potential.”

Suzetrigine is designed to block pain in the peripheral nervous system, rather than the brain. That means it won’t have the “liking” effects of opioids or be as addictive.  

In Phase 3 clinical studies, suzetrigine was more effective in reducing post-operative pain than a placebo after minimally invasive surgeries.  Over 80% of patients rated suzetrigine as good or excellent in treating acute pain, but it was not more effective than a combination of the opioid hydrocodone and acetaminophen, more commonly known as Vicodin.

Vertex hopes suzetrigine will eventually be approved for a variety of pain conditions, not just post-operative pain.  The company has been studying the drug as a treatment for pain caused by diabetic peripheral neuropathy.

“In my 24 years practicing medicine, I have seen firsthand the desperate need for new non-opioid therapies for treating pain. Too many people today are either undertreated, dealing with negative side effects of currently available therapies or foregoing pain medications altogether for fear of becoming dependent on opioids,” said Scott Weiner, MD, a Vertex consultant and Associate Professor of Emergency Medicine at Harvard Medical School.

The Biden Administration has been under pressure from lobbyists, politicians and anti-opioid activists to have the FDA approve more non-opioid medications like suzetrigine. The new analgesics are expected to be far more expensive than opioids and other older pain relievers.

If the FDA approves suzetrigine in January, it will coincide with implementation of the NOPAIN Act, which will expand access to non-opioid analgesics in outpatient surgical settings by making them eligible for higher Medicare reimbursement rates.

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.

Stem Cells Could Help Diabetics Produce Their Own Insulin

By Pat Anson, PNN Editor

With insulin prices soaring out-of-reach for many U.S. patients, there’s hope on the horizon for people with Type 1 diabetes. Researchers are making significant progress in developing stem cell therapies that could restore their ability to produce their own insulin.

Interim findings from two early stage clinical trials, published today in the journals Cell Stem Cell and Cell Reports Medicine, show that pancreatic endoderm cells derived from human pluripotent stem cells (PSCs) began producing insulin in diabetic patients within months of being implanted in a tiny device under the skin.

While the amount of insulin secreted by the cells was not enough to cure Type 1 diabetes, they were sufficient enough to reduce the insulin requirements of some patients by as much as 20% and increase the amount of time spent in their targeted blood glucose range. Both studies showed that the stem cells can survive up to 59 weeks after implantation.

"A landmark has been set. The possibility of an unlimited supply of insulin-producing cells gives hope to people living with type 1 diabetes," says Eelco de Koning, MD, of Leiden University Medical Center in the Netherlands, who co-authored a commentary published in Cell Stem Cell. "Despite the absence of relevant clinical effects, this study will remain an important milestone for the field of human PSC-derived cell replacement therapies as it is one of the first to report cell survival and functionality one year after transplantation."

There are a number of caveats here. Less than three dozen patients participated in the Phase 1/2 studies, the outcomes were highly variable, and there were no control groups to compare the results with. The implanted stem cells were also derived from donors – meaning the patients had to take immunosuppressive drugs to prevent their bodies from rejecting the implants, leaving them vulnerable to infections. At least two patients experienced serious adverse events associated with having their immune systems suppressed.

Researchers still need to determine at what stage the stem cells are optimal for transplantation and the best place to implant them. It is also not clear how long the cells remain effective and whether the need for immunosuppressive therapy can be eliminated.

But the studies demonstrate that stem cells can mimic the insulin-producing pancreas cells that diabetics lack.

“A landmark has been set. The possibility of an unlimited supply of insulin-producing cells gives hope to people living with type 1 diabetes.”

— Eelco de Koning, MD

"The clinical road to wide implementation of stem cell-derived islet replacement therapy for type 1 diabetes is likely to be long and winding,” de Koning says. "But an era of clinical application of innovative stem-cell based islet replacement therapy for the treatment of diabetes has finally begun."    

About 460 million people worldwide have diabetes mellitus, a disorder in which the body does not produce enough insulin, causing blood sugar (glucose) levels to be abnormally high.  In Type 1 diabetes, the body’s immune system attacks the insulin producing cells of the pancreas. Left untreated, diabetes damages blood vessels and significantly raises the risk of stroke, heart attack and diabetic neuropathy.

Diet, exercise and regular insulin injections can help control Type 1 diabetes. But with insulin selling for about $300 a vial in the United States – 10 times more than in other developed countries --  some diabetics have rationed or even stopped taking the life-saving injections.

Another encouraging stem cell study -- involving just one patient -- was recently reported by Vertex Pharmaceuticals. A chronically ill man with Type 1 diabetes who has been taking insulin injections for decades – up to 34 units per day – began producing his own insulin after being injected with an experimental stem cell product called VX-880.

As a test, researchers only injected him with about half the targeted amount of VX-880, but within 90 days the man had reduced his need for insulin injections by 91 percent.

“These results from the first patient treated with VX-880 are unprecedented. What makes these results truly remarkable is that they were achieved with treatment at half the target dose,” Bastiano Sanna, PhD, Executive Vice President of Vertex, said in a statement. “While still early, these results support the continued progression of our VX-880 clinical studies, as well as future studies using our encapsulated islet cells, which hold the potential to be used without the need for immunosuppression.”

Vertex plans to expand the study to eventually include up to 17 patients, at multiple sites in the U.S. and Canada.
