Blenrep for multiple myeloma withdrawn from U.S. market
A drug used in the treatment of relapsed/refractory multiple myeloma (RRMM) is in the process of being pulled off the U.S. market by its manufacturer.
The drug is belantamab mafodotin-blmf (Blenrep), an antibody drug conjugate that targets B-cell maturation antigen (BCMA).
The manufacturer, GSK, announced that it has started the process of withdrawing this drug from the market at the request of the U.S. Food and Drug Administration (FDA).
This request follows disappointing results from a large confirmatory trial, known as DREAMM-3, in which the drug failed to meet the primary endpoint of showing an improvement in progression-free survival (PFS).
The company was obliged to carry out this confirmatory trial after the FDA granted an accelerated approval for the drug in August 2020.
The accelerated approval was based on response data, and it was dependent on later trials’ confirming a clinical benefit. In this case, those trials did not confirm a clinical benefit.
“We respect the Agency’s approach to the accelerated approval regulations and associated process,” commented the GSK Chief Medical Officer Sabine Luik.
The company will continue to “work with the U.S. FDA on a path forward for this important treatment option for patients with multiple myeloma.”
Further clinical trials in the DREAMM program are still underway. Results from the DREAMM-7 and DREAMM-8 trials are expected in early 2023.
The company had high hopes for the drug when it was launched. At that time, belanatamab mafodotin-blmf was the only drug on the market that targeted BCMA, and so it was the first drug in its class.
However, it is no longer unique. In the 2 years that it has been available, several other products that target BCMA have been launched for use in the treatment of multiple myeloma. These include the two chimeric antigen receptor T-cell products, idecabtagene vicleucel (Abecma) and ciltacabtagene autoleucel (Carvykti), as well as the bispecific antibody teclistamab (Tecvayli).
For relapsed/refractory disease
Belantamab mafodotin-blmf was approved for use in patients with RRMM who had already undergone treatment with one of the three major classes of drugs, namely, an immunomodulatory agent, a proteasome inhibitor, and a CD-38 monoclonal antibody.
Patients who are currently taking the drug and would like to continue doing so will have the option to enroll in a compassionate use program to retain their access to treatment, the company said.
“GSK continues to believe, based on the totality of data available from the DREAMM (DRiving Excellence in Approaches to Multiple Myeloma) development program, that the benefit-risk profile of belantamab mafodotin remains favorable in this hard-to-treat RRMM patient population. Patients responding to belantamab mafodotin experienced durable clinical benefit, and safety remains consistent with the known safety profile,” the company said.
Details of DREAMM-3 results
DREAMM-3 was a phase 3 trial that compared single-agent belantamab mafodotin to pomalidomide (Pomalyst) in combination with low-dose dexamethasone (PomDex) for patients with RRMM.
The results for the primary endpoint of PFS did not reach statistical significance: median PFS was 11.2 vs. 7 months with PomDex (hazard ratio, 1.03; 95% confidence interval, 0.72-1.47).
At the time of the primary analysis, the overall survival (OS) data had only achieved 37.5% overall maturity. The median OS was 21.2 vs. 21.1 months with PomDex (HR, 1.14; 95% CI, 0.77-1.68).

At-home births rose during the pandemic, CDC reports
More women gave birth at home in America last year, continuing a pandemic trend and reaching the highest level in decades, according to figures released by the CDC.
The report said that almost 52,000 births occurred at home in 2021, out of 4 million total births in the country. This was an increase of 12% from 2020. The figure rose by 22% in 2020, when the COVID-19 pandemic hit, over 2019.
There were several possible reasons for the increase in home births. Infection rates and hospitalizations were high. Vaccinations were not available or were not widely used, and many people avoided going to hospitals or the doctor, said Elizabeth Gregory, the report’s lead author.
Also, some women didn’t have health insurance, lived far from a medical facility, or could not get to a hospital fast enough. About 25% of home births are not planned, the Associated Press reported.
Increases in home births occurred across all races, but home births were less common among Hispanics.
The AP reported that home births are riskier than hospital births, according to the American College of Obstetricians and Gynecologists. The organization advises against home births for women carrying multiple babies or who have previously had a cesarean section.
“Hospitals and accredited birth centers are the safest places to give birth, because although serious complications associated with labor and delivery are rare, they can be catastrophic,” said Jeffrey Ecker, M.D., chief of obstetrics and gynecology at Massachusetts General Hospital, Boston.

FDA approves first-ever agent to delay type 1 diabetes onset
“Today’s approval of a first-in-class therapy adds an important new treatment option for certain at-risk patients,” said John Sharretts, MD, director of the Division of Diabetes, Lipid Disorders, and Obesity in the FDA’s Center for Drug Evaluation and Research. “The drug’s potential to delay clinical diagnosis of type 1 diabetes may provide patients with months to years without the burdens of disease.”
The agent, which interferes with T-cell-mediated autoimmune destruction of pancreatic beta cells, is the first disease-modifying therapy for impeding progression of type 1 diabetes. It is administered by intravenous infusion once daily for 14 consecutive days.
The specific indication is “to delay the onset of stage 3 type 1 diabetes in adults and pediatric patients 8 years and older who currently have stage 2 type 1 diabetes.” In type 1 diabetes staging, adopted in 2015, stage 1 is defined as the presence of beta cell autoimmunity with two or more islet autoantibodies with normoglycemia, stage 2 is beta-cell autoimmunity with dysglycemia yet asymptomatic, and stage 3 is the onset of symptomatic type 1 diabetes.
Stage 2 type 1 diabetes is associated with a nearly 100% lifetime risk of progression to clinical (stage 3) type 1 diabetes and a 75% risk of developing the condition within 5 years.
The FDA had previously rejected teplizumab for this indication in July 2021, despite a prior endorsement from an advisory panel in May 2021.
Now, with the FDA approval, Provention Bio cofounder and CEO Ashleigh Palmer said in a statement, “This is a historic occasion for the T1D community and a paradigm shifting breakthrough ... It cannot be emphasized enough how precious a delay in the onset of stage 3 T1D can be from a patient and family perspective; more time to live without and, when necessary, prepare for the burdens, complications, and risks associated with stage 3 disease.”
T1D onset delayed by 2 years
In 2019, a pivotal phase 2, randomized, placebo-controlled trial involving 76 at-risk children and adults aged 8 years and older showed that a single 14-day treatment of daily intravenous infusions of teplizumab in 44 patients resulted in a significant median 2-year delay to onset of clinical type 1 diabetes compared with 32 who received placebo.
Those “game changer” data were presented at the American Diabetes Association (ADA) annual meeting in June 2019 and simultaneously published in the New England Journal of Medicine.
Three-year data were presented at the June 2020 ADA meeting and published in March 2021 in Science Translational Medicine, by Emily K. Sims, MD, department of pediatrics, Indiana University, Indianapolis, and colleagues.
At a median follow-up of 923 days, 50% of those randomly assigned to teplizumab remained diabetes free, compared with 22% of those who received placebo infusions (hazard ratio, 0.457; P = .01). The teplizumab group had a greater average C-peptide area under the curve compared with placebo, reflecting improved beta-cell function (1.96 vs. 1.68 pmol/mL; P = .006).
C-peptide levels declined over time in the placebo group but stabilized in those receiving teplizumab (P = .0015).
“The mid-range time from randomization to stage 3 type 1 diabetes diagnosis was 50 months for the patients who received Tzield and 25 months for those who received a placebo. This represents a statistically significant delay in the development of stage 3 type 1 diabetes,” according to the FDA statement.
The most common side effects of Tzield include lymphopenia (73% teplizumab vs. 6% placebo), rash (36% vs. 0%), leukopenia (221% vs. 0%), and headache (11% vs. 6%). Label warnings and precautions include monitoring for cytokine release syndrome, risk for serious infections, and avoidance of live, inactivated, and mRNA vaccines.
This approval is likely to accelerate discussion about universal autoantibody screening. Currently, most individuals identified as having preclinical type 1 diabetes are first-degree relatives of people with type 1 diabetes identified through the federally funded TrialNet program. In December 2020, the type 1 diabetes research and advocacy organization JDRF began offering a $55 home blood test to screen for the antibodies, and other screening programs have been launched in the United States and Europe.
Previous studies have examined cost-effectiveness of universal screening in children and the optimal ages that such screening should take place.
In October, Provention Bio announced a co-promotion agreement with Sanofi for the U.S. launch of Tzield for delay in onset of clinical T1D in at-risk individuals. Provention Bio offers financial assistance options (e.g., copay assistance) to eligible patients for out-of-pocket costs.

FDA grants accelerated approval for new treatment of female cancers
The Food and Drug Administration has granted accelerated approval to mirvetuximab soravtansine (Elahere) for use in pretreated patients with folate receptor (FR) alpha–positive, platinum-resistant epithelial ovarian, fallopian tube, and primary peritoneal cancer. These patients can have received one to three prior lines of treatment.
“ according to labeling.
Mirvetuximab soravtansine is an antibody-drug conjugate (ADC) with an antibody directed against FR alpha that is linked to a microtubule inhibitor conjugate.
This product is a first-in-class ADC directed against FR alpha, a cell-surface protein highly expressed in ovarian cancer, and is the first FDA-approved ADC for platinum-resistant disease, said the manufacturer, ImmunoGen.
Patients are selected for treatment with this drug using a diagnostic test that the FDA approved along with the agent: the VENTANA FOLR1 (FOLR-2.1) RxDx Assay.
FR alpha–positive platinum-resistant ovarian cancer is characterized by limited treatment options and poor outcomes, commented Ursula Matulonis, MD, chief of the division of gynecologic oncology at the Dana-Farber Cancer Institute, Boston, and co–principal investigator of the SORAYA trial that led to the approval. In a company press release, she said results from this trial show that mirvetuximab soravtansine has “impressive antitumor activity, durability of response, and overall tolerability ... [which] demonstrate the benefit of this new therapeutic option.”
The SORAYA trial (also known as Study 0417 [NCT04296890]) was a single-arm trial of 106 patients with FR alpha–positive, platinum-resistant epithelial ovarian, fallopian tube, or primary peritoneal cancer.
These patients were identified as FR alpha positive by using the assay. They were permitted to receive up to three prior lines of systemic therapy, and all patients were required to have received bevacizumab.
All patients received mirvetuximab soravtansine-gynx 6 mg/kg (based on adjusted ideal body weight) as an intravenous infusion every 3 weeks until disease progression or unacceptable toxicity.
The approval was based on an investigator-assessed overall response rate of 31.7%, which included five complete responses, and a median duration of response of 6.9 months.
Safety was evaluated in a pooled analysis from three studies among a total of 464 patients with FR alpha–positive, platinum-resistant epithelial ovarian, fallopian tube, or primary peritoneal cancer who received at least one dose of the drug.
The most common adverse events, occurring in 20% or more of study participants, were vision impairment, fatigue, increased AST level, nausea, increased alanine aminotransferase level, keratopathy, abdominal pain, decreased lymphocytes, peripheral neuropathy, diarrhea, decreased albumin, constipation, increased alkaline phosphatase level, dry eye, decreased magnesium level, decreased leukocyte count, decreased neutrophil count, and decreased hemoglobin level.
Potential participants were excluded if they had corneal disorders, ocular conditions requiring ongoing treatment, peripheral neuropathy above grade 1, or noninfectious interstitial lung disease.
The product labeling contains a boxed warning of ocular toxicity. Full prescribing information is available.

FR alpha–positive platinum-resistant ovarian cancer is characterized by limited treatment options and poor outcomes, commented Ursula Matulonis, MD, chief of the division of gynecologic oncology at the Dana-Farber Cancer Institute, Boston, and co–principal investigator of the SORAYA trial that led to the approval. In a company press release, she said results from this trial show that mirvetuximab soravtansine has “impressive antitumor activity, durability of response, and overall tolerability ... [which] demonstrate the benefit of this new therapeutic option.”
The SORAYA trial (also known as Study 0417 [NCT04296890]) was a single-arm trial of 106 patients with FR alpha–positive, platinum-resistant epithelial ovarian, fallopian tube, or primary peritoneal cancer.
These patients were identified as FR alpha positive by using the assay. They were permitted to receive up to three prior lines of systemic therapy, and all patients were required to have received bevacizumab.
All patients received mirvetuximab soravtansine-gynx 6 mg/kg (based on adjusted ideal body weight) as an intravenous infusion every 3 weeks until disease progression or unacceptable toxicity.
The approval was based on an investigator-assessed overall response rate of 31.7%, which included five complete responses, and a median duration of response of 6.9 months.
Safety was evaluated in a pooled analysis from three studies among a total of 464 patients with FR alpha–positive, platinum-resistant epithelial ovarian, fallopian tube, or primary peritoneal cancer who received at least one dose of the drug.
The most common adverse events, occurring in 20% or more of study participants, were vision impairment, fatigue, increased AST level, nausea, increased alanine aminotransferase level, keratopathy, abdominal pain, decreased lymphocytes, peripheral neuropathy, diarrhea, decreased albumin, constipation, increased alkaline phosphatase level, dry eye, decreased magnesium level, decreased leukocyte count, decreased neutrophil count, and decreased hemoglobin level.
Potential participants were excluded if they had corneal disorders, ocular conditions requiring ongoing treatment, peripheral neuropathy above grade 1, or noninfectious interstitial lung disease.
The product labeling contains a boxed warning of ocular toxicity. Full prescribing information is available.

Teclistamab for MM: Lifesaver or 'cause of death'?
Following “unprecedented” results in a phase 1/2 study, teclistamab (Tecvayli, Janssen Biotech) received accelerated approval from the Food and Drug Administration for adults with relapsed/refractory multiple myeloma who had received at least four lines of therapy. Typically, patients in this situation have just a few weeks to live.
This is “unprecedented” said Nikhil Munshi, MD, professor of medicine at Harvard Medical School, Boston, who was not involved with the study. “Pomalidomide got approved with 30% response rate, carfilzomib got approved with 29% response rate, selinexor got approved with 31% response rate and so on and on. ... So here is teclistamab with [this] response rate in patients having five, six lines of treatment. ...[It’s] going to be so much in demand because it’s a great drug.”
The first cut of the data appeared in the New England Journal of Medicine.
At the 6-month mark, 90.6% of patients who responded had no progression of their disease, and at 9 months, 66.5% of patients were still holding steady.
Senior investigator in the trial, Saad Usmani, MD, of Memorial Sloan Kettering Cancer Center, New York, said: “What was most striking was the high response rates and the durability of response.”
Dr. Usmani said ease of administration was the other aspect of teclistamab that impressed him. The drug is given by subcutaneous injection weekly after a short ramp-up period.
He contrasted this regimen with that of chimeric antigen receptor (CAR) T-cell therapy, the only alternative with similar efficacy in such sick patients: “I can prescribe [teclistamab] today, and my patient gets it tomorrow,” Dr. Usmani said. “With CAR T, I prescribe today and it will take 4-6 weeks for us to collect T cells and another 6-7 weeks for the product to come back.” Dr. Usmani said many patients die before CAR T reaches them.
Community oncology will benefit greatly from teclistamab, especially patients for whom CAR T isn’t feasible, said Kashyap Patel, MD, president of the Community Oncology Alliance. “My patients are most of them underserved minority-class populations with myeloma, and they cannot travel many miles to go to a CAR T center. With sub[cutaneous] injection, the patient can have [teclistamab] administered in their doctor’s office and continue to live their normal life.”
However, how should the wider oncology community make sense of a drug approval based solely on response in a single-arm, phase 1/2 study, with no survival data?
Dr. Patel said, “Phase 1 plus phase 2 data is probably a little bit quick, but time will tell eventually.” He cited melflufen as a cautionary tale: a product given accelerated approval for multiple myeloma, then withdrawn when new data showed that it increased the risk of death.
When Dr. Munshi was asked about trial design for accelerated approvals, he responded, “you are touching a topic very close to my heart, a topic of great significance currently.”
He went on to say that overall survival (OS) is no longer a viable trial endpoint in diseases like multiple myeloma for several reasons. Most significantly, he noted: “Survival has gone up to 10 or 15 years [so] today, if you randomize between one [drug] versus another, there are going to be seven or eight more treatments before the patient dies.”
Similarly, progression-free survival (PFS) in multiple myeloma is now as much as 5 years, Dr. Munshi said. “Do we want a patient to wait 5 years to get a very good new drug?”
For these reasons and others, Dr, Munshi observed, myeloma researchers are increasingly relying on a surrogate called “negative minimal residual disease” (negative MRD) – in other words, a situation in which myeloma cells can no longer be detected in the bone marrow. MRD is hunted out using next-generation flow or next-generation sequencing of myeloma-cell DNA from bone-marrow aspirate to levels as low as 1 in 100,000 or 1,000,000 cells.
In 2020, Dr. Munshi and colleagues published a large meta-analysis showing that a negative MRD in a patient with multiple myeloma was significantly prognostic for both progression-free survival (hazard ratio, 0.33; P < .001) and overall survival (HR, 0.45; P < .001). The team concluded: “MRD can fulfill all the prerequisites to be a clinically valid surrogate biomarker for PFS and OS in [multiple myeloma].”
In MajesTEC-1 overall, 26.7% of patients on teclistamab had no signs of residual disease at a threshold of 1 in 100,000. Among patients who showed a “complete response” by International Myeloma Working Group criteria, 46% had no residual disease.
Dr. Munshi stressed that such patients are not necessarily “cured.” It will take a few more years to prove that. He noted: “Simply, physiologically, [negative MRD] means that if a patient has one [myeloma] cell in a million, that cell is going to take a much longer time to grow up to be myeloma.”
On Nov. 8 and 9, the FDA and the International Myeloma Society held a workshop to discuss the vexed question of surrogate endpoints and single-arm studies for drug approvals entitled the “Future of Drug Development in Multiple Myeloma.” Dr. Munshi was cochair.
A panelist at the meeting who was a senior investigator in the MajesTEC-1 trial, Ajai Chari, MD, professor of medicine at the Icahn School of Medicine at Mount Sinai, New York, summed up the dilemma: “No one disagrees that randomized studies are the best way of doing things. The question is, if you’re a patient who’s exhausted all available therapies, do you have that time to wait? ... The role of accelerated approval is to get the drug to the patient faster. But what does it not pick up? How do we make these accelerated approvals more meaningful and not have to retract for safety?”
Jonathon Vallejo, also on the panel, agreed that safety was the key worry. The ideal scenario for accelerated approval would be a drug that was better than available therapy, and “in some sense, it’s much safer.” However, such situations are rare.
“Most of the time, we don’t have these products that come in that have no toxicity signals,” he said. “So one thing we have to think carefully about in the single-arm trial setting is, what are the toxicities? How do they stack up?”
Dr. Chari said that, for his part, he wanted to see more transparency around “cause of death” in all studies that lead to accelerated approvals. He said he was “tired” of seeing a death labeled as “not attributed” to the drug by the investigator or the drug company.
“Let me decide. Show me the deaths, and show me the myeloma status at that point,” Dr. Chari said. “That’s a signal – if you’re a responding patient and dying, then the FDA should be a little bit more cautious.”
The FDA has added a boxed warning to the teclistamab product information concerning cytokine-release syndrome and neurologic toxicity.
Cytokine-release syndrome, the most common side effect overall, showed up in 72% of patients, typically 2 days after the first step-up dose.
Neurologic toxicity occurred in 57% of patients, including headache (25%), motor dysfunction (16%), sensory neuropathy (15%) and encephalopathy (13%). About 6%of patients developed a serious, life-threatening neurologic condition called immune effector cell–associated neurotoxicity syndrome.
Overall, serious adverse reactions occurred in 54% of participants in MajesTEC-1, and 5% of people in the trial died from adverse reactions during the study, most commonly infections.
Because of its safety profile, teclistamab is available only through a restricted program called TECVAYLI Risk Evaluation and Mitigation Strategy.
The continued approval of teclistamab for this indication “may be contingent upon verification and description of clinical benefit in confirmatory trials,” according to the FDA.
To that end, eight more studies of teclistamab are underway, aiming for approximately 1,300 multiple myeloma patients around the world. Three of these trials are in newly diagnosed patients. Four more studies are planned to come online in the next 3 months, raising the final tally of patients testing out teclistamab to approximately 4,700. The trials will look at teclistamab in sequence or in combination with standards such as bortezomib and pomalidomide. All studies are open label.
Dr. Patel believes that, until these trials say otherwise, the benefits of teclistamab outweigh the risks. “I’m very happy we have one more option in this space, particularly the fourth or fifth line for patients who want to continue to fight the disease,” Dr. Patel concluded.
Dr. Munshi disclosed advisory board/consultant work for Adaptive, Abbvie, Amgen, Bristol-Myers Squibb, Celgene, Janssen, Karyopharm, Legend, Millennium, Novartis, Oncopep, and Pfizer and is the scientific founder of Oncopep and DCT. The 2020 meta-analysis by Dr. Munshi and colleagues was funded by Janssen-Cilag. Dr. Patel declared funding from Janssen for a diversity-equity initiative and membership of the South Carolina Medicaid P & T Committee. Dr. Usmani declared conflicts of interest with Amgen, BMS/Celgene, GlaxoSmithKline, Janssen, Merck, Pharmacyclics, Sanofi, Seattle Genetics, Abbvie, Genentech, Gilead, Sanofi, Seattle Genetics, SecuraBio, SkylineDX, Takeda, and TeneoBio.

FROM THE NEW ENGLAND JOURNAL OF MEDICINE
FDA puts REMS requirements on hold to ensure continuity of care
In a Nov. 2 notice on its website, the FDA said it is aware that health care professionals and patients continue to experience ongoing difficulties with the clozapine REMS program, including issues with patient access to clozapine following discharge from inpatient care.
A chief concern is that inpatient pharmacies are only allowed to dispense a 7-days’ supply of clozapine to the patient upon discharge.
To address this issue, the FDA said it will now (temporarily) not object if inpatient pharmacies dispense a days’ supply of clozapine that aligns with the patient’s monitoring frequency.
For example, a 7-days’ supply for weekly monitoring, a 14-days’ supply for twice-monthly monitoring, and a 30-days’ supply for monthly monitoring upon discharge from an inpatient facility.
Clozapine is a second-generation (atypical) antipsychotic used to treat schizophrenia that is not well controlled with standard antipsychotics.
While clozapine can be highly effective in some patients, it also carries serious risks, including a decrease in neutrophil count, which can lead to severe neutropenia, serious infections, and death.
As a result, those taking the drug must undergo regular absolute neutrophil count monitoring. Clozapine REMS is intended to maximize the benefits of the drug and minimize risk.
The FDA says it will continue to exercise earlier enforcement discretion regarding the clozapine REMS program announced back in November 2021. This includes allowing pharmacists to dispense clozapine without a REMS dispense authorization and allowing wholesalers to ship clozapine to pharmacies and health care settings without confirming enrollment in the REMS.
“We understand that difficulties with the clozapine REMS program have caused frustration and have led to problems with patient access to clozapine. FDA takes these concerns seriously. Continuity of care, patient access to clozapine, and patient safety are our highest priorities,” the FDA says.
The agency is working closely with the clozapine REMS program administrators to address these challenges and avoid interruptions in patient care.
The FDA encourages pharmacists and prescribers to continue working with the clozapine REMS to complete certification and prescribers to enroll patients in the program.

New CDC guidance on prescribing opioids for pain
The 2022 Clinical Practice Guideline provides guidance on determining whether to initiate opioids for pain; selecting opioids and determining opioid dosages; deciding duration of initial opioid prescription and conducting follow-up; and assessing risk and addressing potential harms of opioid use.
“Patients with pain should receive compassionate, safe, and effective pain care. We want clinicians and patients to have the information they need to weigh the benefits of different approaches to pain care, with the goal of helping people reduce their pain and improve their quality of life,” Christopher M. Jones, PharmD, DrPH, acting director for the CDC’s National Center for Injury Prevention and Control, said in a news release.
How to taper safely
The last guideline on the topic was released by CDC in 2016. Since then, new evidence has emerged regarding the benefits and risks of prescription opioids for acute and chronic pain, comparisons with nonopioid pain treatments, dosing strategies, opioid dose-dependent effects, risk mitigation strategies, and opioid tapering and discontinuation, the CDC says.
A “critical” addition to the 2022 guideline is advice on tapering opioids, Dr. Jones said during a press briefing.
“Practical tips on how to taper in an individualized patient-centered manner have been added to help clinicians if the decision is made to taper opioids, and the guideline explicitly advises against abrupt discontinuation or rapid dose reductions of opioids,” Dr. Jones said.
“That is based on lessons learned over the last several years as well as new science about how we approach tapering and the real harms that can result when patients are abruptly discontinued or rapidly tapered,” he added.
The updated guideline was published online Nov. 3 in the Morbidity and Mortality Weekly Report.
Key recommendations in the 100-page document include the following:
- In determining whether or not to initiate opioids, nonopioid therapies are at least as effective as opioids for many common types of acute pain. Use of nondrug and nonopioid drug therapies should be maximized as appropriate, and opioid therapy should only be considered for acute pain if it is anticipated that benefits outweigh risks to the patient.
- Before starting opioid therapy, providers should discuss with patients the realistic benefits and known risks of opioid therapy.
- Before starting ongoing opioid therapy for patients with subacute pain lasting 1 to 3 months or chronic pain lasting more than 3 months, providers should work with patients to establish treatment goals for pain and function, and consideration should be given as to how opioid therapy will be discontinued if benefits do not outweigh risks.
- Once opioids are started, the lowest effective dose of immediate-release opioids should be prescribed for no longer than needed for the expected duration of pain severe enough to require opioids.
- Within 1 to 4 weeks of starting opioid therapy for subacute or chronic pain, providers should work with patients to evaluate and carefully weigh benefits and risks of continuing opioid therapy; care should be exercised when increasing, continuing, or reducing opioid dosage.
- Before starting and periodically during ongoing opioid therapy, providers should evaluate risk for opioid-related harms and should work with patients to incorporate relevant strategies to mitigate risk, including offering naloxone and reviewing potential interactions with any other prescribed medications or substance used.
- Abrupt discontinuation of opioids should be avoided, especially for patients receiving high doses.
- For treating patients with opioid use disorder, treatment with evidence-based medications should be provided, or arrangements for such treatment should be made.
Dr. Jones emphasized that the guideline is “voluntary and meant to guide shared decision-making between a clinician and patient. It’s not meant to be implemented as absolute limits of policy or practice by clinicians, health systems, insurance companies, governmental entities.”
He also noted that the “current state of the overdose crisis, which is very much driven by illicit synthetic opioids, is not the aim of this guideline.
“The release of this guideline is really about advancing pain care and improving the lives of patients living with pain,” he said.
“We know that at least 1 in 5 people in the country have chronic pain. It’s one of the most common reasons why people present to their health care provider, and the goal here is to advance pain care, function, and quality of life for that patient population, while also reducing misuse, diversion, and consequences of prescription opioid misuse,” Dr. Jones added.

FDA rejects bulevirtide for hepatitis D
The U.S. Food and Drug Administration (FDA) has declined to approve bulevirtide, Gilead Sciences’ drug for the treatment of hepatitis delta virus (HDV) infection and compensated liver disease.
In a complete response letter, the FDA voiced concerns over the production and delivery of bulevirtide, an investigational, first-in-class HDV entry-inhibitor that received conditional approved in Europe in 2020.
The FDA did not request new studies to evaluate the safety and efficacy of bulevirtide.
As reported previously by this news organization, data from an ongoing phase 3 trial showed that after 48 weeks of treatment, almost half of those treated with bulevirtide achieved the combined primary endpoint of reduced or undetectable HDV RNA levels and normalized alanine aminotransferase levels.
Chronic HDV infection is the most severe form of viral hepatitis. It is associated with a poor prognosis and high mortality rates.
There are currently no approved treatments for HDV in the United States. Bulevirtide was granted breakthrough therapy and orphan drug designations by the FDA.
Merdad Parsey, MD, PhD, chief medical officer, Gilead Sciences, wrote in a news release that the company looks forward to “continuing our active discussions with FDA so that we may bring bulevirtide to people living with HDV in the U.S. as soon as possible.”
This is the second manufacturing-related complete response letter Gilead has received in the past 8 months. In March, the FDA rejected the long-acting HIV drug lenacapavir. The drug was sanctioned in Europe and the United Kingdom in September.

FDA OKs teclistamab for relapsed/refractory multiple myeloma
The results made the case for “teclistamab as a monotherapy for eligible patients with heavily pretreated multiple myeloma, in need of new treatment options,” investigator Maria-Victoria Mateos, MD, PhD, a hematologist at the University Hospital of Salamanca (Spain) said in a June press release from drug maker Janssen/Johnson & Johnson.
The approval was based on the phase 1-2 single-arm MajesTEC-1 trial. The MajesTEC-1 findings, published in August in the New England Journal of Medicine, included 165 patients with relapsed or refractory multiple myeloma after at least three therapy lines – including an immunomodulatory drug, a proteasome inhibitor, and an anti-CD38 antibody. These patients received a weekly subcutaneous 1.5 mg/kg injection of teclistamab after stepping up from 0.06 mg and 0.3 mg/kg doses.
According to the FDA announcement, the overall response rate was nearly 62%. And the estimated duration of response rate among responders was 90.6% at 6 months and 66.5% at 9 months.
The NEJM results also indicated that almost 40% of patients had a complete response to the therapy, over a median follow-up of 14.1 months. More than a quarter of patients (26.7%) had no minimal residual disease.
The study investigators concluded that “teclistamab resulted in a high rate of deep and durable response in patients with triple-class exposed relapsed or refractory multiple myeloma.”
In a press release, Michael Andreini, president and CEO of the Multiple Myeloma Research Foundation, commented that “teclistamab is an important new treatment option for patients who have faced multiple relapses.”
The recommended dose for teclistamab is 0.06 mg/kg via subcutaneous injection on day 1, 0.3 mg/kg on day 4, and 1.5 mg/kg on day 7, followed by 1.5 mg/kg once weekly until disease progression or unacceptable toxicity.
The FDA noted, however, that the prescribing information for teclistamab comes with a Boxed warning for “life-threatening or fatal cytokine-release syndrome (CRS) and neurologic toxicity, including immune effector cell–associated neurotoxicity (ICANS).”
CRS was reported in 72.1% of patients (grade 3 in one patient but no grade 4 cases), neurologic toxicity in 57%, and ICANS in 6%. Other common adverse events in the NEJM report included neutropenia in 71% of subjects (grade 3 or 4 in 64%); anemia in 52% (grade 3 or 4 in 37%), and thrombocytopenia in 40% (grade 3 or 4 in 21%). Overall, 45% of patients developed grade 3 or 4 infections.
“Because of the risks of CRS and neurologic toxicity, including ICANS, teclistamab-cqyv is available only through a restricted program under a Risk Evaluation and Mitigation Strategy (REMS), called the Tecvayli REMS,” according to the FDA’s press release.
Teclistamab is a T-cell–bispecific antibody that targets both CD3 expressed on the surface of T cells and B-cell maturation antigen (BCMA) expressed on the surface of myeloma cells, activating T-cells to kill cancer cells that express the antigen.
Three BCMA-directed therapies are already on the market in the United States that carry teclistamab’s indication: the antibody-drug conjugate belantamab mafodotin (Blenrep) and two chimeric antigen receptor (CAR) T-cell therapies, idecabtagene vicleucel (Abecma) and ciltacabtagene autoleucel (Carvykti).
The overall response rate is approximately 31% with belantamab mafodotin, 67% for idecabtagene vicleucel, and 83% for ciltacabtagene autoleucel.
Pfizer also has a bispecific BCMA-CD3–targeted antibody in development, elranatamab, for triple-class refractory multiple myeloma that is expected to compete with teclistamab.
MajesTEC-1 was funded by Janssen. Dr. Mateos is a paid speaker and consultant for the company.

Three BCMA-directed therapies are already on the market in the United States that carry teclistamab’s indication: the antibody-drug conjugate belantamab mafodotin (Blenrep) and two chimeric antigen receptor (CAR) T-cell therapies, idecabtagene vicleucel (Abecma) and ciltacabtagene autoleucel (Carvykti).
The overall response rate is approximately 31% with belantamab mafodotin, 67% for idecabtagene vicleucel, and 83% for ciltacabtagene autoleucel.
Pfizer also has a bispecific BCMA-CD3–targeted antibody in development, elranatamab, for triple-class refractory multiple myeloma that is expected to compete with teclistamab.

FDA approves new immunotherapy combo for liver cancer
(HCC), the most common type of liver cancer.
The new combination comprises a single dose of tremelimumab (Imjudo, AstraZeneca) followed by treatment with durvalumab (Imfinzi, AstraZeneca) in what is known as the STRIDE (single-tremelimumab regular-interval durvalumab) regimen.
This marks the first worldwide approval for tremelimumab, which is a CTLA-4 antibody.
The other drug in the combination, durvalumab, is an anti-PDL1 antibody and is already approved by the FDA for use in several tumor types, including lung cancer, bladder cancer, and biliary tract cancers.
The STRIDE regimen is composed of a single 300-mg dose of tremelimumab followed by durvalumab 1,500 mg given every 4 weeks.
This regimen was used in the HIMALAYA phase 3 trial, which was published in June 2022 in the New England Journal of Medicine.
Results from this trial showed that 30% of patients treated with that combination were still alive at 3 years, compared with 20% of patients who were treated with the standard regimen, sorafenib.
“In addition to this regimen demonstrating a favorable 3-year survival rate in the HIMALAYA trial, safety data showed no increase in severe liver toxicity or bleeding risk for the combination, important factors for patients with liver cancer who also have advanced liver disease,” commented the principal investigator of this trial, Ghassan Abou-Alfa, MD, MBA, attending physician at Memorial Sloan Kettering Cancer Center, New York.
“Patients with unresectable liver cancer are in need of well-tolerated treatments that can meaningfully extend overall survival,” he commented in a press release from the drug’s manufacturer, AstraZeneca.
When the results from this trial were presented earlier this year at the ASCO Gastrointestinal Cancers meeting, the discussant for that abstract, Anthony B. El-Khoueiry, MD, from the University of Southern California, Norris Comprehensive Cancer Center, Los Angeles, suggested that the STRIDE regimen offers a new first-line treatment option for patients with advanced HCC.
He also made several comments about the design of the HIMALAYA trial, which has a third treatment arm in which patients received durvalumab alone. Dr. El-Khoueiry noted that single-agent durvalumab was noninferior to sorafenib, but he added that no conclusions could be drawn about the STRIDE regimen in comparison with durvalumab as a single agent, because the trial was not powered for that.
The STRIDE regimen showed a lower risk of bleeding in comparison with combinations that include VEGF inhibitors (such as bevacizumab), he said, but he also pointed out that this trial excluded patients with main portal vein thrombosis, who are at high risk of bleeding.
Details of adverse events
In the NEJM article, the trialists report that grade 3/4 treatment-emergent adverse events occurred in 50.5% of patients with STRIDE, 37.1% with durvalumab alone, and 52.4% of patients with sorafenib.
The manufacturer noted that severe and fatal immune-mediated adverse reactions may occur, including immune-mediated pneumonitis, colitis, hepatitis, endocrinopathies, dermatologic reactions, and others.
The company also noted that among the patients with unresectable HCC in the HIMALAYA study who received the STRIDE regimen, the most common adverse reactions (occurring in ≥ 20% of patients) were rash, diarrhea, fatigue, pruritus, musculoskeletal pain, and abdominal pain.
Serious adverse reactions occurred in 41% of patients and included hemorrhage (6%), diarrhea (4%), sepsis (2.1%), pneumonia (2.1%), rash (1.5%), vomiting (1.3%), acute kidney injury (1.3%), and anemia (1.3%).
Fatal adverse reactions occurred in 8% of patients who received the combination, including death (1%), intracranial hemorrhage (0.5%), cardiac arrest (0.5%), pneumonitis (0.5%), hepatic failure (0.5%), and immune-mediated hepatitis (0.5%).
Permanent discontinuation of the treatment regimen because of an adverse reaction occurred in 14% of patients.
