ChemoCentryx, the drug’s manufacturer, today announced that the U.S. Food and Drug Administration approved the drug as an adjunctive treatment for severe active antineutrophil cytoplasmic autoantibody–associated vasculitis (also known as ANCA-associated vasculitis or ANCA vasculitis).

This systemic disease results from overactivation of the complement system, leading to inflammation and eventual destruction of small blood vessels. This can lead to organ damage and failure, with the kidney as the major target, said the company in a statement.

The avacopan approval was based in large part on the results of the ADVOCATE trial, which were highlighted in a February 2021 editorial in the New England Journal of Medicine , titled “Avacopan – Time to replace glucocorticoids?” But the FDA-approved indication for avacopan is as an adjunctive treatment of adult patients with severe active ANCA-associated vasculitis (granulomatosis with polyangiitis [GPA] and microscopic polyangiitis [MPA]) in combination with standard therapy including glucocorticoids. “Tavneos does not eliminate glucocorticoid use,” the label states.

The ADVOCATE trial was a global, randomized, double-blind, active-controlled, double-dummy phase 3 trial of 330 patients with ANCA-associated vasculitis conducted in 20 countries, ChemoCentryx said. Participants were randomly assigned to receive either rituximab or cyclophosphamide (followed by azathioprine/mycophenolate) and either avacopan or study-supplied oral prednisone.

Subjects in both treatment groups could also receive nonprotocol glucocorticoids as needed. The study met its primary endpoints of disease remission at 26 weeks and sustained remission at 52 weeks, as assessed by the Birmingham Vasculitis Activity Score (BVAS), ChemoCentryx said. Common adverse reactions among study participants included nausea, headache, hypertension, diarrhea, vomiting, rash, fatigue, upper abdominal pain, dizziness, blood creatinine increase, and paresthesia.

In the ChemoCentryx statement, Peter A. Merkel, MD, MPH, a consultant to the company and the chief of rheumatology at the University of Pennsylvania, Philadelphia, called the avacopan clearance a “first-in-a-decade approval of a medicine for ANCA-associated vasculitis.”

“Patients will now have access to a new class of medication that provides beneficial effects for the treatment of ANCA-associated vasculitis,” Dr. Merkel said.

In reviewing the avacopan application, the FDA noted that the medicine is intended to treat “a rare and serious disease associated with high morbidity and increased mortality.”

“It is also a disease with high unmet need for new therapies,” the FDA staff said in a review of the ChemoCentryx application for approval of avacopan, which was posted online ahead of a meeting this past May.

Previous FDA concerns

In that review, FDA staff made public various concerns about the evidence used in seeking approval of the medicine. The FDA staff said there were “substantial uncertainties around the phase 3 study design and results, raising questions about the adequacy of this single trial to inform the benefit-risk assessment.”

Members of the FDA’s Arthritis Advisory Committee voted 10-8 on May 6 on a question of whether the risk-benefit profile of avacopan is adequate to support approval. The panel also voted 9-9 on whether the efficacy data support approval of avacopan, and 10-8 that the safety profile of avacopan is adequate to support approval.

ChemoCentryx in July said it filed an amendment to its new drug application (NDA) for avacopan. This appears to have answered regulators’ questions about the drug.

On a call with analysts Friday, ChemoCentryx officials outlined a marketing strategy for avacopan, with efforts focused on reaching influential rheumatologists and nephrologists. The company will set a U.S. wholesale acquisition cost for the drug of about $150,000-$200,000 a patient, in keeping with the range of prices often seen for orphan drugs. ChemoCentryx said it intends to offer financial support programs for the medicine.

ChemoCentryx said avacopan is also approved for the treatment of microscopic polyangiitis and granulomatosis with polyangiitis (the two main forms of ANCA-associated vasculitis) in Japan. The regulatory decision in Europe is expected by the end of this year.

Psychological therapy that changes an individual’s beliefs about pain not only provides lasting chronic pain relief but also alters brain regions related to pain generation, new research shows.

In the first randomized controlled test of pain-reprocessing therapy (PRT), two-thirds of patients with chronic back pain (CBP) who received 4 weeks of PRT were pain free or nearly pain free afterward – and for most patients, relief was maintained for 1 year, the researchers found.

“Primary chronic back pain can be dramatically reduced or even eliminated by psychological treatment focused on changing how threatening we perceive the pain to be,” first author Yoni Ashar, PhD, department of psychiatry, Weill Cornell Medicine, New York, said in an interview.

“We were very surprised” by the impact, Dr. Ashar admitted, given that large reductions in pain have rarely been observed in studies that tested psychological therapies for chronic back pain.

The study was published online Sept. 29, 2021, in JAMA Psychiatry.
 

Rethinking pain

CBP is a leading cause of disability, and treatment is often ineffective. In about 85% of cases of primary CBP, a definitive cause of the pain can’t be identified. In these cases, fear, avoidance, and beliefs that pain indicates injury may contribute to ongoing CBP.

PRT educates patients about the role of the brain in generating chronic pain; helps them reappraise their pain as they engage in movements that they had been afraid to undertake; and helps them address emotions that may exacerbate pain.

The study included 151 adults (54% women; mean age, 41 years) who had primary CBP of low to moderate severity (mean pain intensity, 4 of 10) for an average of 10 years.

A total of 50 participants were randomly allocated to undergo PRT (one telehealth session with a physician and eight PRT sessions over 4 weeks), 51 to receive placebo (subcutaneous saline injection in the back), and 50 to continue their routine, usual ongoing care.

Large group differences in pain were observed after treatment. The mean pain score was 1.18 in the PRT group, 2.84 in the placebo group, and 3.13 in the usual-care group. Hedges’ g was –1.14 for PRT versus placebo and –1.74 for PRT versus usual care (P < .001).

Two-thirds (66%) of adults in the PRT group were pain free or nearly pain free following treatment (pain-intensity score of 0 or 1 out of 10), compared with 20% of those in the placebo group and 10% of those who received usual care.

Treatment effects were maintained at 1-year follow-up. The mean pain score was 1.51 in the PRT group, 2.79 in the placebo group, and 3.00 in the usual-care group. Neither age nor sex moderated the effect of PRT on pain intensity.
 

Retraining the brain

The researchers said the effects of PRT on pain were mediated by lessening the belief that pain indicates tissue damage. Of note, PRT also reduced experimentally evoked back pain and spontaneous pain during functional MRI, with large effect sizes.

“The idea is that by thinking about the pain as safe rather than threatening, patients can alter the brain networks reinforcing the pain, and neutralize it,” Dr. Ashar said in a news release.

The authors noted that study participants were relatively well educated and active. The participants reported having longstanding low to moderate pain and disability at baseline.

The physician and therapists were experts in delivering PRT. Future studies should test generalizability to other patient populations, therapists, and treatment contexts.

“Our clinical experience shows that PRT is effective for other primary chronic pain conditions as well,” said Dr. Ashar, including primary knee pain and tension headache.
 

Restoring function

Commenting on the findings, Shaheen E. Lakhan, MD, PhD, neurologist and pain specialist in Newton, Mass., said he has long experience using psychological approaches to address pain, with good results.

“Imagine telling a person suffering from decades of chronic pain that your pain is all in your head. I’ve done that for years as a board-certified pain physician managing only the most severe and debilitating forms of pain. When used to ground brain retraining, I could ultimately restore function to people living with chronic pain,” Dr. Lakhan said.

“The statement is true – the brain ultimately processes signals from throughout the body, forms the perception of pain, and links it to emotional brain centers, among others. Pain is an important survival mechanism so that when your body is at threat of injury, you protect yourself from further damage and withdraw. The problem lies when pain outlasts its welcome and chronifies,” said Dr. Lakhan, senior vice president of research and development of Click Therapeutics in Boston.

The investigators in this study “eloquently prove” that with 4 weeks of PRT, patients can learn that chronic pain is largely a “brain-generated false alarm and that constantly affirming this truth can actually reduce or eliminate it,” Dr. Lakhan said.

“Further, the brain areas implicated with pain are calmed after going through the therapy to both resting pain and pain induced by extending the back,” he noted.

“Pain-reprocessing therapy can improve the lives of chronic [pain patients] who have low to moderate levels of pain and disability; however, much work needs to be done to make this scalable and universally available and covered by insurers as a treatment modality,” Dr. Lakhan added.

He cautioned that he has not seen therapies such as this work when there is significant depression, withdrawal, or lack of control over one’s situation such that one behaves in a helpless manner – “a terrible state of mind called learned helplessness.”

The study was funded by the National Institutes of Health, the National Center for Advancing Translational Sciences, the Radiological Society of North America, the German Research Foundation, the Psychophysiologic Disorders Association, the Foundation for the Study of the Therapeutic Encounter, and community donations. Dr. Ashar received grants from the National Institutes of Health during the conduct of the study and personal fees from UnitedHealth Group, Lin Health, Pain Reprocessing Therapy Center, and Mental Health Partners of Boulder County outside the submitted work. Dr. Lakhan disclosed no relevant financial relationships.

Anthem Blue Cross, the country’s second-biggest health insurance company, is behind on billions of dollars in payments owed to hospitals and doctors because of onerous new reimbursement rules, computer problems and mishandled claims, say hospital officials in multiple states.

Anthem, like other big insurers, is using the COVID-19 crisis as cover to institute “egregious” policies that harm patients and pinch hospital finances, said Molly Smith, group vice president at the American Hospital Association. “There’s this sense of ‘Everyone’s distracted. We can get this through.’ ”

Hospitals are also dealing with a spike in retroactive claims denials by UnitedHealthcare, the biggest health insurer, for ED care, the AHA said.

Disputes between insurers and hospitals are nothing new. But this fight sticks more patients in the middle, worried they’ll have to pay unresolved claims. Hospitals say it is hurting their finances as many cope with COVID surges – even after the industry has received tens of billions of dollars in emergency assistance from the federal government.

“We recognize there have been some challenges” to prompt payments caused by claims-processing changes and “a new set of dynamics” amid the pandemic, Anthem spokesperson Colin Manning said in an email. “We apologize for any delays or inconvenience this may have caused.”

Virginia law requires insurers to pay claims within 40 days. In a Sept. 24 letter to state insurance regulators, VCU Health, a system that operates a large teaching hospital in Richmond associated with Virginia Commonwealth University, said Anthem owes it $385 million. More than 40% of the claims are more than 90 days old, VCU said.

For all Virginia hospitals, Anthem’s late, unpaid claims amount to “hundreds of millions of dollars,” the Virginia Hospital and Healthcare Association said in a June 23 letter to state regulators.

Nationwide, the payment delays “are creating an untenable situation,” the American Hospital Association said in a Sept. 9 letter to Anthem CEO Gail Boudreaux. “Patients are facing greater hurdles to accessing care; clinicians are burning out on unnecessary administrative tasks; and the system is straining to finance the personnel and supplies” needed to fight Covid.

Complaints about Anthem extend “from sea to shining sea, from New Hampshire to California,” AHA CEO Rick Pollack told KHN.

Substantial payment delays can be seen on Anthem’s books. On June 30, 2019, before the pandemic, 43% of the insurer’s medical bills for that quarter were unpaid, according to regulatory filings. Two years later that figure had risen to 53% – a difference of $2.5 billion.

Anthem profits were $4.6 billion in 2020 and $3.5 billion in the first half of 2021.

Alexis Thurber, who lives near Seattle, was insured by Anthem when she got an $18,192 hospital bill in May for radiation therapy that doctors said was essential to treat her breast cancer.

The treatments were “experimental” and “not medically necessary,” Anthem said, according to Ms. Thurber. She spent much of the summer trying to get the insurer to pay up – placing two dozen phone calls, spending hours on hold, sending multiple emails and enduring unmeasurable stress and worry. It finally covered the claim months later.

“It’s so egregious. It’s a game they’re playing,” said Ms. Thurber, 51, whose cancer was diagnosed in November. “Trying to get true help was impossible.”

Privacy rules prevent Anthem from commenting on Ms. Thurber’s case, said Anthem spokesperson Colin Manning.

When insurers fail to promptly pay medical bills, patients are left in the lurch. They might first get a notice saying payment is pending or denied. A hospital might bill them for treatment they thought would be covered. Hospitals and doctors often sue patients whose insurance didn’t pay up.

Hospitals point to a variety of Anthem practices contributing to payment delays or denials, including new layers of document requirements, prior-authorization hurdles for routine procedures and requirements that doctors themselves – not support staffers – speak to insurance gatekeepers. “This requires providers to literally leave the patient[’s] bedside to get on the phone with Anthem,” AHA said in its letter.

Anthem often hinders coverage for outpatient surgery, specialty pharmacy and other services in health systems listed as in network, amounting to a “bait and switch” on Anthem members, AHA officials said.

“Demanding that patients be treated outside of the hospital setting, against the advice of the patient’s in-network treating physician, appears to be motivated by a desire to drive up Empire’s profits,” the Greater New York Hospital Association wrote in an April letter to Empire Blue Cross, which is owned by Anthem.

Anthem officials pushed back in a recent letter to the AHA, saying the insurer’s changing rules are intended partly to control excessive prices charged by hospitals for specialty drugs and nonemergency surgery, screening and diagnostic procedures.

Severe problems with Anthem’s new claims management system surfaced months ago and “persist without meaningful improvement,” AHA said in its letter.

Claims have gotten lost in Anthem’s computers, and in some cases VCU Health has had to print medical records and mail them to get paid, VCU said in its letter. The cash slowdown imposes “an unmanageable disruption that threatens to undermine our financial footing,” VCU said.

United denied $31,557 in claims for Emily Long’s care after she was struck in June by a motorcycle in New York City. She needed surgery to repair a fractured cheekbone. United said there was a lack of documentation for “medical necessity” – an “incredibly aggravating” response on top of the distress of the accident, Ms. Long said.

The Brooklyn hospital that treated Ms. Long was “paid appropriately under her plan and within the required time frame,” said United spokesperson Maria Gordon Shydlo. “The facility has the right to appeal the decision.”

United’s unpaid claims came to 54% as of June 30, about the same level as 2 years previously.

When Erin Conlisk initially had trouble gaining approval for a piece of medical equipment for her elderly father this summer, United employees told her the insurer’s entire prior-authorization database had gone down for weeks, said Ms. Conlisk, who lives in California.

“There was a brief issue with our prior-authorization process in mid-July, which was resolved quickly,” Gordon Shydlo said.

When asked by Wall Street analysts about the payment backups, Anthem executives said it partly reflects their decision to increase financial reserves amid the health crisis.

“Really a ton of uncertainty associated with this environment,” John Gallina, the company’s chief financial officer, said on a conference call in July. “We’ve tried to be extremely prudent and conservative in our approach.”

During the pandemic, hospitals have benefited from two extraordinary cash infusions. They and other medical providers have received more than $100 billion through the CARES Act of 2020 and the American Rescue Plan of 2021. Last year United, Anthem and other insurers accelerated billions in hospital reimbursements.

The federal payments enriched many of the biggest, wealthiest systems while poorer hospitals serving low-income patients and rural areas struggled.

Those are the systems most hurt now by insurer payment delays, hospital officials said. Federal relief funds “have been a lifeline, but they don’t make people whole in terms of the losses from increased expenses and lost revenue as a result of the COVID experience,” Mr. Pollack said.

Several health systems declined to comment about claims payment delays or didn’t respond to a reporter’s queries. Among individual hospitals “there is a deep fear of talking on the record about your largest business partner,” AHA’s Ms. Smith said.

Alexis Thurber worried she might have to pay her $18,192 radiation bill herself, and she’s not confident her Anthem policy will do a better job next time of covering the cost of her care.

“It makes me not want to go to the doctor anymore,” she said. “I’m scared to get another mammogram because you can’t rely on it.”

Anthem Blue Cross, the country’s second-biggest health insurance company, is behind on billions of dollars in payments owed to hospitals and doctors because of onerous new reimbursement rules, computer problems and mishandled claims, say hospital officials in multiple states.

Anthem, like other big insurers, is using the COVID-19 crisis as cover to institute “egregious” policies that harm patients and pinch hospital finances, said Molly Smith, group vice president at the American Hospital Association. “There’s this sense of ‘Everyone’s distracted. We can get this through.’ ”

Hospitals are also dealing with a spike in retroactive claims denials by UnitedHealthcare, the biggest health insurer, for ED care, the AHA said.

Disputes between insurers and hospitals are nothing new. But this fight sticks more patients in the middle, worried they’ll have to pay unresolved claims. Hospitals say it is hurting their finances as many cope with COVID surges – even after the industry has received tens of billions of dollars in emergency assistance from the federal government.

“We recognize there have been some challenges” to prompt payments caused by claims-processing changes and “a new set of dynamics” amid the pandemic, Anthem spokesperson Colin Manning said in an email. “We apologize for any delays or inconvenience this may have caused.”

Virginia law requires insurers to pay claims within 40 days. In a Sept. 24 letter to state insurance regulators, VCU Health, a system that operates a large teaching hospital in Richmond associated with Virginia Commonwealth University, said Anthem owes it $385 million. More than 40% of the claims are more than 90 days old, VCU said.

For all Virginia hospitals, Anthem’s late, unpaid claims amount to “hundreds of millions of dollars,” the Virginia Hospital and Healthcare Association said in a June 23 letter to state regulators.

Nationwide, the payment delays “are creating an untenable situation,” the American Hospital Association said in a Sept. 9 letter to Anthem CEO Gail Boudreaux. “Patients are facing greater hurdles to accessing care; clinicians are burning out on unnecessary administrative tasks; and the system is straining to finance the personnel and supplies” needed to fight Covid.

Complaints about Anthem extend “from sea to shining sea, from New Hampshire to California,” AHA CEO Rick Pollack told KHN.

Substantial payment delays can be seen on Anthem’s books. On June 30, 2019, before the pandemic, 43% of the insurer’s medical bills for that quarter were unpaid, according to regulatory filings. Two years later that figure had risen to 53% – a difference of $2.5 billion.

Anthem profits were $4.6 billion in 2020 and $3.5 billion in the first half of 2021.

Alexis Thurber, who lives near Seattle, was insured by Anthem when she got an $18,192 hospital bill in May for radiation therapy that doctors said was essential to treat her breast cancer.

The treatments were “experimental” and “not medically necessary,” Anthem said, according to Ms. Thurber. She spent much of the summer trying to get the insurer to pay up – placing two dozen phone calls, spending hours on hold, sending multiple emails and enduring unmeasurable stress and worry. It finally covered the claim months later.

About half of patients with rheumatoid arthritis who taper or stop disease-modifying antirheumatic drugs (DMARDs) retain stable remission after 12 months, and a majority of those who do relapse regain remission when back on their original treatments, according to data from the open-label, randomized Rheumatoid Arthritis in Ongoing Remission (RETRO) study.

“Currently, 40%-50% of patients with rheumatoid arthritis reach stable remission,” as a result of factors including earlier diagnosis and a wider range of treatments, Koray Tascilar, MD, of Friedrich Alexander University Erlangen-Nuremberg (Germany) and colleagues wrote in their publication of the RETRO trial results in Lancet Rheumatology.

Previous studies have suggested that patients with RA in sustained remission may be able to taper or withdraw treatment, but data from randomized trials are limited, the researchers said.

In the RETRO trial, researchers compared three strategies for RA patients in remission, which was defined as <2.6 on the 28-joint Disease Activity Score with erythrocyte sedimentation rate (DAS28-ESR). They randomized 100 adults to continue DMARDs and glucocorticoids, 102 to taper DMARDs and glucocorticoids to half their prior doses, and 101 to reduce the doses to half for 6 months and then stop DMARDs. Patients were enrolled between May 26, 2010, and May 29, 2018, from 14 treatment centers in Germany. The final analysis included 282 patients; 92 in the continuation group, 93 in the taper group, and 96 in the stop group. The mean age of the patients was 56.5 years, and 59% were women. The mean duration of RA was 7.4 years, and the mean duration of remission was 20 months.

Overall, at 12 months, 61% of the patients remained in remission without relapse; 81.2% of the continuation group, 58.6% of the taper group, and 43.3% of the stop group. Relapses occurred in 17%, 43%, and 55% of patients in the continuation, taper, and stop groups, respectively. The median times to relapse in the three groups were 30.6 weeks, 24.3 weeks, and 26.1 weeks, respectively.

Most of the relapses occurred between weeks 24 and 36 after stopping treatment, the researchers wrote. Corresponding hazard ratios for relapse were 3.02 for the taper group and 4.34 for the stop group, compared with the continuation group. In comparison to continuing treatment, the number needed to treat for one more relapse to occur during the 12-month observation period was four for tapering and three for stopping, they noted.

The study protocol called for a return to baseline treatment for any patients who relapsed in the taper and stop groups, and most patients who relapsed regained remission after restarting their baseline treatments. Among patients who had a follow-up visit after a relapse, 10 (63%) of 16 patients in the continuation group reachieved remission before the end of the study, as did 21 (62%) of 34 in the taper group and 35 (76%) of 46 in the stop group.

The most common treatments at baseline were methotrexate (76%) and tumor necrosis factor (TNF) inhibitors (32%).

The researchers also identified several baseline characteristics associated with relapse. Overall, relapse occurred more often in biologic DMARD users than in participants treated with other drugs, more often in women than men, and more often in those with a longer disease duration, higher baseline DAS28-ESR and Health Assessment Questionnaire scores, and in those who were positive for rheumatoid factor or anti–citrullinated protein antibodies.

A total of 38 serious adverse events occurred in 29 participants during the study period, but none were deemed treatment related, and none led to study withdrawal.

The study findings were limited by several factors including the lack of masking of patients and assessors and potential underestimation of disease activity, the researchers noted. Also, the study did not include radiographic data that might have been used to confirm progression; however, such data could have produced a null result and were not feasible in the study population, they wrote.

“If RETRO had been a trial to test the superiority of 100% dose continuation, compared with tapering plus rescue treatment or stopping plus rescue treatment, we would not be able to show that continuation is superior to tapering or stopping,” the researchers noted.

The study results support “an increasingly dynamic management approach in patients with rheumatoid arthritis in stable remission,” given the changing nature of RA management, that may help reduce overtreatment in many RA patients, the researchers concluded. “Furthermore, the observation that most of the patients regained remission after reintroduction of antirheumatic treatments is helpful with regard to the benefit-risk aspect of treatment reduction.”

Real-world setting serves as starting point

The RETRO study is unique in that it tried to reflect a real-life setting by enrolling patients on baseline treatment with combinations of conventional synthetic DMARDs and biologic DMARDs seen in clinical practice rather than only patients taking biologic DMARDs – primarily TNF inhibitors – as done in previous studies of tapering and stopping DMARDs, wrote Catherine L. Hill, MD, of the University of Adelaide (Australia), in an accompanying editorial. It is also “used a simple, pragmatic one-size-fits-all treatment-tapering strategy,” she wrote.

However, she emphasized that answers are needed to questions about what relapse rates are acceptable, what duration of treatment-free time is ideal, and whether benefits to the patient outweigh risks.

Dr. Hill also highlighted the issue of identifying patients who are appropriate candidates for tapering or withdrawal. Stricter remission criteria may not be feasible in routine practice, and so “the development of algorithms to guide patient selection is likely to be the most practical way forward for clinicians and patients,” she wrote.

“Contemplation of treatment tapering or discontinuation in some patients with rheumatoid arthritis is remarkable and a measure of how far treatments have advanced,” Dr. Hill wrote. “However, further work to address outstanding questions on who should taper and how best to do it is still required,” she concluded.

The study received no outside funding. Lead author Dr. Tascilar disclosed lecture fees from Gilead and Union Chimique Belge; several coauthors disclosed relationships with multiple companies outside the current study. Dr. Hill had no financial conflicts to disclose.

The mean duration of RA was 7.4 years, and the mean duration of remission was 20 months.

Overall, at 12 months, 61% of the patients remained in remission without relapse; 81.2% of the continuation group, 58.6% of the taper group, and 43.3% of the stop group. Relapses occurred in 17%, 43%, and 55% of patients in the continuation, taper, and stop groups, respectively. The median times to relapse in the three groups were 30.6 weeks, 24.3 weeks, and 26.1 weeks, respectively.

Most of the relapses occurred between weeks 24 and 36 after stopping treatment, the researchers wrote. Corresponding hazard ratios for relapse were 3.02 for the taper group and 4.34 for the stop group, compared with the continuation group. In comparison to continuing treatment, the number needed to treat for one more relapse to occur during the 12-month observation period was four for tapering and three for stopping, they noted.

The study protocol called for a return to baseline treatment for any patients who relapsed in the taper and stop groups, and most patients who relapsed regained remission after restarting their baseline treatments. Among patients who had a follow-up visit after a relapse, 10 (63%) of 16 patients in the continuation group reachieved remission before the end of the study, as did 21 (62%) of 34 in the taper group and 35 (76%) of 46 in the stop group.

The most common treatments at baseline were methotrexate (76%) and tumor necrosis factor (TNF) inhibitors (32%).

The researchers also identified several baseline characteristics associated with relapse. Overall, relapse occurred more often in biologic DMARD users than in participants treated with other drugs, more often in women than men, and more often in those with a longer disease duration, higher baseline DAS28-ESR and Health Assessment Questionnaire scores, and in those who were positive for rheumatoid factor or anti–citrullinated protein antibodies.

A total of 38 serious adverse events occurred in 29 participants during the study period, but none were deemed treatment related, and none led to study withdrawal.

The study findings were limited by several factors including the lack of masking of patients and assessors and potential underestimation of disease activity, the researchers noted. Also, the study did not include radiographic data that might have been used to confirm progression; however, such data could have produced a null result and were not feasible in the study population, they wrote.

“If RETRO had been a trial to test the superiority of 100% dose continuation, compared with tapering plus rescue treatment or stopping plus rescue treatment, we would not be able to show that continuation is superior to tapering or stopping,” the researchers noted.

The study results support “an increasingly dynamic management approach in patients with rheumatoid arthritis in stable remission,” given the changing nature of RA management, that may help reduce overtreatment in many RA patients, the researchers concluded. “Furthermore, the observation that most of the patients regained remission after reintroduction of antirheumatic treatments is helpful with regard to the benefit-risk aspect of treatment reduction.”

Real-world setting serves as starting point

The RETRO study is unique in that it tried to reflect a real-life setting by enrolling patients on baseline treatment with combinations of conventional synthetic DMARDs and biologic DMARDs seen in clinical practice rather than only patients taking biologic DMARDs – primarily TNF inhibitors – as done in previous studies of tapering and stopping DMARDs, wrote Catherine L. Hill, MD, of the University of Adelaide (Australia), in an accompanying editorial. It is also “used a simple, pragmatic one-size-fits-all treatment-tapering strategy,” she wrote.

However, she emphasized that answers are needed to questions about what relapse rates are acceptable, what duration of treatment-free time is ideal, and whether benefits to the patient outweigh risks.

Dr. Hill also highlighted the issue of identifying patients who are appropriate candidates for tapering or withdrawal. Stricter remission criteria may not be feasible in routine practice, and so “the development of algorithms to guide patient selection is likely to be the most practical way forward for clinicians and patients,” she wrote.

“Contemplation of treatment tapering or discontinuation in some patients with rheumatoid arthritis is remarkable and a measure of how far treatments have advanced,” Dr. Hill wrote. “However, further work to address outstanding questions on who should taper and how best to do it is still required,” she concluded.

The study received no outside funding. Lead author Dr. Tascilar disclosed lecture fees from Gilead and Union Chimique Belge; several coauthors disclosed relationships with multiple companies outside the current study. Dr. Hill had no financial conflicts to disclose.

Soon after Merck announced on Oct. 1 that it would ask federal regulators for emergency use authorization (EUA) for its auspicious new COVID-19 pill, the accolades began.

Former Food and Drug Administration chief Scott Gottlieb, MD, told CNBC the drug was “a profound game changer.” Top infectious disease expert Anthony S. Fauci, MD, called the early data “impressive.” The World Health Organization termed it “certainly good news,” while saying it awaits more data.

Merck, partnering with Ridgeback Biotherapeutics on the investigational oral antiviral medicine molnupiravir, plans to submit applications to regulatory agencies worldwide, hoping to deliver the first oral antiviral medication for COVID-19. 

Interim clinical trial results show that the drug may slash the risk for hospitalization or death by 50% in those with mild to moderate COVID-19.

When the results were found to be so favorable, the study was halted at the recommendation of an independent data-monitoring committee and in consultation with the FDA.

That initial enthusiasm is now tempered with some perspective on the pros and cons. “This anticipated drug has gotten a little more hype than it deserves,” said William Schaffner, MD, professor of preventive medicine and infectious disease specialist at Vanderbilt University Medical Center in Nashville, Tenn. He and others suggest a reality check.

“It’s not exactly a home run, like penicillin for strep throat,” agreed Carl Fichtenbaum, MD, professor of infectious diseases at the University of Cincinnati, who is investigating a similar pill for a rival company, Atea, partnering with Roche. 

“But it is encouraging,” he said. “It will probably be an incremental improvement on what we have.” The fact that it can be taken at home is a plus: “Anything we can do to keep people from getting sicker is a good thing.”

“The data show in this higher risk group [those who were studied had at least one risk factor for severe COVID-19, such as age or a medical condition], it reduces the risk of advancing to severe disease by 50%,” Dr. Schaffner said. While that’s a clear benefit for half, it of course leaves the other half without benefit, he said.

Others critiqued the predicted cost of the drug. The U.S. government has already agreed to pay about $700 per patient, according to a new report from Harvard T. H. Chan School of Public Health, Boston, and King’s College Hospital, London. That analysis concluded that the actual cost of production for the 5-day course is $17.74.

“We fully expect that having an oral treatment that reduces the risk of hospitalizations will be significantly cost effective for society,” Melissa Moody, a Merck spokesperson, told this news organization. “We are optimistic that molnupiravir can become an important medicine as part of the global effort to fight the pandemic.”

Merck expects to produce 10 million courses of treatment by the end of the year, with additional doses expected to be produced in 2022, according to a company press release. Earlier in 2021, Merck finalized its agreement with the U.S. government to supply about 1.7 million courses of the drug at the $700 price, once an EUA or FDA approval is given.

Merck also has supply and purchase agreements with other governments worldwide, pending regulatory approval.
 

Study details

Details about the study findings came from a Merck press release. In the planned interim analysis, Merck and Ridgeback evaluated data from 775 patients initially enrolled in the phase 3 MOVe-OUT trial.

All adults had lab-confirmed mild to moderate COVID-19, and reported onset of symptoms within 5 days of being randomly assigned to the drug or placebo. All had at least one risk factor linked with poor disease outcome (such as older age or obesity).

The drug is a ribonucleoside and works by creating mutations in the virus’s genome, halting the ability of the virus to replicate.

Through day 29 of the study, the drug reduced the risk or hospitalization or death by about 50%. While 7.3% of those who received the drug either died or were hospitalized by day 29, 14.1% of those on placebo did, a statistically significant difference (P = .0012).

Side effects were similar in both groups, with 35% of the drug-treated and 40% of the placebo group reporting some side effect, Merck reported. Adverse drug-related events were 12% in the drug group and 11% in the placebo group. While 1.3% of the drug-treated group quit the study because of an adverse event, 3.4% of the placebo group quit.
 

Pros, cons, and unknowns

The ability to take the drug orally, and at home, is a definite plus, Dr. Schaffner said,  compared with the monoclonal antibody treatment currently approved that must be given intravenously or subcutaneously and in certain locations.

More people could be reached and helped with the option of an at-home, oral medicine, he and others agreed.

The regimen for molnupiravir is four pills, two times daily, for 5 days, even if symptoms are mild. As with other prescription drugs, “there will always be folks who don’t comply completely” with the prescribed regimen, Dr. Schaffner said. With this pill, that might be especially true if the symptoms are very mild.

The 50% reduction is not as effective as the benefit often quoted for monoclonal antibody treatment. In clinical trials of Regeneron’s monoclonal antibody treatment, the regimen reduced COVID-19–related hospitalization or death in high-risk patients by 70%.

Even so, the new pill could change the pandemic’s course, others say. “I think molnupiravir has the potential to change how we take care of people who have COVID and risk factors for developing severe disease,” Rajesh Tim Gandhi, MD, an infectious disease physician at Massachusetts General Hospital and Harvard Medical School in Boston, told this news organization. 

“What we’ll need to do, however, is make sure that people get tested quickly after they develop symptoms and, if they’re confirmed to have COVID, start on the pills within 5 days of developing symptoms,” he said, while warning that more data are needed about the drug and the trial results.

Another concern is that the promise of a pill will stall vaccination rates, with some people figuring why get vaccinated when they can obtain the pill if they do get sick.

Relying on treatment alone won’t work, Dr. Schaffner said. “Let’s [also] focus on prevention, which is the vaccine. We have to keep working both sides of the street.”

Dr. Gandhi added: “It’s important to remember that even though molnupiravir reduced the likelihood of hospitalization and death, a number of people who received the drug still got sick enough to end up in the hospital.”

Also unknown, he said, is how severe their disease was and whether they will develop long COVID.

The Merck study included only unvaccinated people. Might it work for those vaccinated people who get a breakthrough infection? “From a purely scientific perspective, there is no reason to believe molnupiravir would not work in people who are vaccinated, but the overall efficacy on top of the vaccine is likely dependent on how well they were able to mount a protective immune response to the vaccine,” Ms. Moody said. Still, Merck believes the pill could be of benefit for these infections too, she added.

As for the expected cost, Ms. Moody said that the company takes into account a number of factors in setting pricing, “but fundamentally we look at the impact of the disease, the benefits that the drug delivers to patients and to society, and at supporting ongoing drug development.”
 

On Merck’s heels: Pfizer, Roche, Atea

Pfizer is studying an antiviral pill, PF-07321332, a protease inhibitor that blocks the protease enzymes and halts replication of the virus.

In addition to studying the drug in infected patients at high risk of severe illness and in those at typical risk, Pfizer launched a phase 2-3 study in late September that will enroll people who live in the same household as a person with a confirmed, symptomatic COVID-19 infection to see if the drug can prevent disease in those who have been exposed.

Atea and Roche’s COVID pill, AT527, is in phase 3 trials as well. AT527 is an inhibitor of polymerase, an enzyme many viruses have, to stop replications. Atea is evaluating the drug to reduce disease “burden” and for both pre- and postexposure prevention.
 

Big picture: Role of COVID-19 pills

It may be necessary to target the coronavirus with more than one antiviral agent, said Dr. Fichtenbaum, a principal investigator for the AT527 trials. 

“Sometimes viruses require two or three active agents to control their replication,” he said, citing information gleaned from other viral research, such as HIV. For control of HIV infection, a cocktail or combination of antivirals is often recommended.

That may well be the case for COVID-19, Dr. Fichtenbaum said. The goal would be to attack the virus at more than one pathway.

Music plus mushrooms equals therapy

Magic mushrooms have been used recreationally and medicinally for thousands of years, but researchers have found adding music could be a game changer in antidepressant treatment.

chrissmith12/Pixabay

The ingredient that makes these mushrooms so magical is psilocybin. It works well for the clinical treatment of mental health conditions and some forms of depression because the “trip” can be contained to one work day, making it easy to administer under supervision. With the accompaniment of music, scientists have found that psilocybin evokes emotion.

This recent study, presented at the European College of Neuropsychopharmacology Congress in Lisbon, tested participants’ emotional response to music before and after the psilocybin. Ketanserin, an antihypertensive drug, was used to test against the effects of psilocybin. The scientist played Mozart and Elgar and found that participants on psilocybin had an emotional response increase of 60%. That response was even greater, compared with ketanserin, which actually lessened the emotional response to music.

“This shows that combination of psilocybin and music has a strong emotional effect, and we believe that this will be important for the therapeutic application of psychedelics if they are approved for clinical use,” said lead researcher Dea Siggaard Stenbæk of the University of Copenhagen.

Professor David J. Nutt of Imperial College in London, who was not involved in the study, said that it supports the use of music for treatment efficacy with psychedelics and suggested that the next step is to “optimise this approach probably through individualising and personalising music tracks in therapy.”

Cue the 1960s LSD music montage.
 

Chicken ‘white striping is not a disease’

Have you ever sliced open a new pack of chicken breasts to start dinner and noticed white fatty lines running through the chicken? Maybe you thought it was just some extra fat to trim off, but the Humane League calls it “white striping disease.”

rawpixel

Chicken is the No. 1 meat consumed by Americans, so it’s not surprising that chickens are factory farmed and raised to be ready for slaughter quickly, according to CBSNews.com, which reported that the Humane League claims white striping is found in 70% of the chicken in popular grocery stores. The league expressed concern for the chickens’ welfare as they are bred to grow bigger quickly, which is causing the white striping and increasing the fat content of the meat by as much as 224%.

The National Chicken Council told CBS that the league’s findings were unscientific. A spokesperson said, “White striping is not a disease. It is a quality factor in chicken breast meat caused by deposits of fat in the muscle during the bird’s growth and development.” He went on to say that severe white striping happens in 3%-6% of birds, which are mostly used in further processed products, not in chicken breast packages.

Somehow, that’s not making us feel any better.
 

The itsy bitsy spider lets us all down

Most people do not like spiders. That’s too bad, because spiders are generally nothing but helpful little creatures that prey upon annoying flies and other pests. Then there’s the silk they produce. The ancient Romans used it to treat conditions such as warts and skin lesions. Spiders wrap their eggs in silk to protect them from harmful bacteria.

Simon Fruergaard

Of course, we can hardly trust the medical opinions of people from 2,000 years ago, but modern-day studies have not definitively proved whether or not spider silk has any antimicrobial properties.

To settle the matter once and for all, researchers from Denmark built a silk-harvesting machine using the most famous of Danish inventions: Legos. The contraption, sort of a paddle wheel, pulled the silk from several different species of spider pinned down by the researchers. The silk was then tested against three different bacteria species, including good old Escherichia coli.

Unfortunately for our spider friends, their silk has no antimicrobial activity. The researchers suspected that any such activity seen in previous studies was actually caused by improper control for the solvents used to extract the silk; those solvents can have antimicrobial properties on their own. As for protecting their eggs, rather than killing bacteria, the silk likely provides a physical barrier alone.

It is bad news for spiders on the benefit-to-humanity front, but look at the bright side: If their silk had antimicrobial activity, we’d have to start farming them to acquire more silk. And that’s no good. Spiders deserve to roam free, hunt as they please, and drop down on your head from the ceiling.
 

Anxiety and allergies: Cause, effect, confusion

We’re big fans of science, but as longtime, totally impartial (Science rules!) observers of science’s medical realm, we can see that the day-to-day process of practicing the scientific method occasionally gets a bit messy. And no, we’re not talking about COVID-19.

We’re talking allergies. We’re talking mental health. We’re talking allergic disease and mental health.

We’re talking about a pair of press releases we came across during our never-ending search for material to educate, entertain, and astound our fabulously wonderful and loyal readers. (We say that, of course, in the most impartial way possible.)

The first release was titled, “Allergies including asthma and hay fever not linked to mental health traits” and covered research from the University of Bristol (England). The investigators were trying to determine if “allergic diseases actually causes mental health traits including anxiety, depression, bipolar disorder, and schizophrenia, or vice versa,” according to the release.

What they found, however, was “little evidence of a causal relationship between the onset of allergic disease and mental health.” Again, this is the press release talking.

The second release seemed to suggest the exact opposite: “Study uncovers link between allergies and mental health conditions.” That got our attention. A little more reading revealed that “people with asthma, atopic dermatitis, and hay fever also had a higher likelihood of having depression, anxiety, bipolar disorder, or neuroticism.”

One of the investigators was quoted as saying, “Establishing whether allergic disease causes mental health problems, or vice versa, is important to ensure that resources and treatment strategies are targeted appropriately.”

Did you notice the “vice versa”? Did you notice that it appeared in quotes from both releases? We did, so we took a closer look at the source. The second release covered a group of investigators from the University of Bristol – the same group, and the same study, in fact, as the first one.

So there you have it. One study, two press releases, and one confused journalist. Thank you, science.

Music plus mushrooms equals therapy

Magic mushrooms have been used recreationally and medicinally for thousands of years, but researchers have found adding music could be a game changer in antidepressant treatment.

The ingredient that makes these mushrooms so magical is psilocybin. It works well for the clinical treatment of mental health conditions and some forms of depression because the “trip” can be contained to one work day, making it easy to administer under supervision. With the accompaniment of music, scientists have found that psilocybin evokes emotion.

This recent study, presented at the European College of Neuropsychopharmacology Congress in Lisbon, tested participants’ emotional response to music before and after the psilocybin. Ketanserin, an antihypertensive drug, was used to test against the effects of psilocybin. The scientist played Mozart and Elgar and found that participants on psilocybin had an emotional response increase of 60%. That response was even greater, compared with ketanserin, which actually lessened the emotional response to music.

“This shows that combination of psilocybin and music has a strong emotional effect, and we believe that this will be important for the therapeutic application of psychedelics if they are approved for clinical use,” said lead researcher Dea Siggaard Stenbæk of the University of Copenhagen.

Professor David J. Nutt of Imperial College in London, who was not involved in the study, said that it supports the use of music for treatment efficacy with psychedelics and suggested that the next step is to “optimise this approach probably through individualising and personalising music tracks in therapy.”

Cue the 1960s LSD music montage.
 

Chicken ‘white striping is not a disease’

Have you ever sliced open a new pack of chicken breasts to start dinner and noticed white fatty lines running through the chicken? Maybe you thought it was just some extra fat to trim off, but the Humane League calls it “white striping disease.”

Chicken is the No. 1 meat consumed by Americans, so it’s not surprising that chickens are factory farmed and raised to be ready for slaughter quickly, according to CBSNews.com, which reported that the Humane League claims white striping is found in 70% of the chicken in popular grocery stores. The league expressed concern for the chickens’ welfare as they are bred to grow bigger quickly, which is causing the white striping and increasing the fat content of the meat by as much as 224%.

The National Chicken Council told CBS that the league’s findings were unscientific. A spokesperson said, “White striping is not a disease. It is a quality factor in chicken breast meat caused by deposits of fat in the muscle during the bird’s growth and development.” He went on to say that severe white striping happens in 3%-6% of birds, which are mostly used in further processed products, not in chicken breast packages.

Somehow, that’s not making us feel any better.
 

The itsy bitsy spider lets us all down

Most people do not like spiders. That’s too bad, because spiders are generally nothing but helpful little creatures that prey upon annoying flies and other pests. Then there’s the silk they produce. The ancient Romans used it to treat conditions such as warts and skin lesions. Spiders wrap their eggs in silk to protect them from harmful bacteria.

Simon Fruergaard

Of course, we can hardly trust the medical opinions of people from 2,000 years ago, but modern-day studies have not definitively proved whether or not spider silk has any antimicrobial properties.

To settle the matter once and for all, researchers from Denmark built a silk-harvesting machine using the most famous of Danish inventions: Legos. The contraption, sort of a paddle wheel, pulled the silk from several different species of spider pinned down by the researchers.

Any pause in taking the osteoporosis drug risedronate (Actonel) should last no longer than 2 years rather than the 2-3 years currently recommended for bisphosphonates, new research suggests.

BananaStock/thinkstockphotos.com

In a cohort of patients aged 66 and older in Ontario, Canada, those who had been taking risedronate had a 34% greater risk of a hip fracture during year 2 to year 3 of a pause in taking the drug – a drug holiday – compared with those who had been taking alendronate (Fosamax). 

The study showed that “risedronate, which has a shorter half-life, confers relatively less hip fracture protection than alendronate during drug holidays longer than 2 years and careful monitoring and follow-up after 2 years is likely warranted,” Kaley (Kaleen) N. Hayes, Pharm D, PhD, summarized in an oral presentation at the annual meeting of the American Society for Bone and Mineral Research. Dr. Hayes is an assistant professor in the department of health services, policy, and practice at Brown University School of Public Health, Providence, R.I.

“Although alendronate and risedronate have similar effectiveness for preventing fractures on treatment, our findings suggest that older patients on a risedronate drug holiday may benefit from assessment to consider resuming therapy after 2 years to prevent hip fractures,” she elaborated in an email.

Juliet Compston, MD, identified this study as one of the meeting’s clinical science highlights.

“This is the first study to directly compare fracture incidence during a drug holiday after treatment with the two most commonly prescribed oral bisphosphonates, alendronate and risedronate,” she told this news organization in an email.

The difference in fracture incidence during the 3-year drug holiday is “consistent with the known difference in pharmacokinetic properties of the two drugs,” noted Dr. Compston, professor of bone medicine and honorary consultant physician at the University of Cambridge (England) School of Clinical Medicine.

Since the increased risk of fracture after stopping risedronate vs. alendronate was seen by 2 years, “reevaluation of risk in risedronate-treated patients should therefore be considered earlier than the recommended period of 2-3 years after discontinuation,” she said.

“The study does not provide information about the optimal duration of drug holiday for either risedronate or alendronate, but it supports a shorter duration for the former of up to 2 years,” according to Dr. Compston.

Study rationale and findings

“The question of whether people treated for osteoporosis with oral bisphosphonates should have drug holidays is controversial,” Dr. Compston noted, “but many guidelines recommend that in lower-risk individuals who have received bisphosphonates for 5 years, a break from treatment of 2-3 years should be considered.”

Five or more years of bisphosphonate treatment for osteoporosis has been associated with rare adverse effects such as atypical femoral fractures, and these drugs appear to have fracture protection effects that linger for a while, so a drug holiday is recommended for most patients, Dr. Hayes added.

Guidelines such as the 2016 ASBMR task force report on long-term bisphosphonates for osteoporosis, she continued, “acknowledge that evidence for this recommendation comes primarily from the extension trial for alendronate, and patients undergoing a risedronate drug holiday may need to be reassessed earlier because of risedronate’s shorter half-life.”

Compared with alendronate, risedronate accumulates less in the bone and is eliminated more quickly from the body, so its fracture protection during drug holidays may be shorter.

The researchers aimed to estimate the 3-year fracture risk after discontinuing long-term (3 or more years) risedronate vs. alendronate therapy among older adults in Ontario.

From health care administrative data, they identified 120,368 patients aged 66 years and older who had started taking risedronate or alendronate as initial therapy for osteoporosis during the period 2000-2016. They had taken the therapy for 3 or more years (with at least 80% adherence) before stopping it for 120 days or longer.

The researchers found that 45% of patients were taking risedronate and 55% were taking alendronate, which are the main bisphosphonates used in Ontario, Dr. Hayes noted. Etidronate (Didronel) is recommended as second-line therapy and accounts for less than 2% of patients starting oral bisphosphonate therapy. 

In an earlier study, the researchers identified a shift toward greater use of risedronate than alendronate since 2008, likely related to newer formulations (for example, monthly and weekly delayed-release formulations of risedronate vs. only weekly alendronate formulations).

The researchers matched 25,077 patients taking alendronate with 25,077 patients taking risedronate, based on fracture risk–related characteristics, including demographics, diagnoses, medication use, and health care use.

The patients had a mean age of 74 when they started taking an oral bisphosphonate; 82% were women and most were White.  

Most patients (78%) had received a prescription from a general practitioner and, on average, they took the bisphosphonate therapy for 5.9 years before the drug holiday.  

The primary outcome of incident hip fracture during a 3-year drug holiday occurred in 915 patients. There were 12.4 events per 1,000 patients in the risedronate group vs. 10.6 events per 1,000 patients in the alendronate group (hazard ratio, 1.18; 95% confidence interval, 1.04-1.34).

The risks were not significantly higher during year 1 or year 2 of the drug holiday, but the curves began to diverge after 2 years, coauthor Suzanne Cadarette, PhD, of the Leslie Dan Faculty of Pharmacy at the University of Toronto, explained when replying to a question after the presentation. Dr. Cadarette supervised this PhD dissertation research by Dr. Hayes.

The researchers acknowledged that the limitations of their study include a lack of information about race or bone mineral density, and the findings may not apply to a younger, more racially diverse population.

The research was supported by the University of Toronto Dalla Lana School of Public Health and the Leslie Dan Faculty of Pharmacy, a Canadian Institutes of Health Research grant, and a doctoral research award. The authors have disclosed no relevant financial relationships.

“Postmenopausal women with low bone mass should obtain adequate calcium and vitamin D and participate in bone-loading exercises,” researchers noted in a recent study published in Osteoporosis International.

“Additional use of bisphosphonates will increase bone mineral density (BMD), especially at the spine,” wrote Nancy Waltman, PhD, College of Nursing, University of Nebraska Medical Center, Omaha, and colleagues.

The findings are partial results from the Heartland Osteoporosis Prevention Study (HOPS), which randomized women who had entered menopause within the previous 6 months and had osteopenia (low bone mass, T score –1.0 to –2.49) to receive one of three treatments for 12 months:

• Bone-loading and resistance exercise plus calcium and vitamin D supplements.
• Risedronate plus calcium and vitamin D supplements.
• Calcium and vitamin D supplements alone (control).

At 1 year, “risedronate significantly increased BMD at the spine, compared to exercise and control, and serum biomarkers of bone turnover also significantly reduced in the risedronate group,” Laura Bilek, PT, PhD, said during an oral presentation of the research at the annual meeting of the American Society for Bone and Mineral Research.

However, the results also showed that, importantly, “in postmenopausal women, exercise appears to improve strength at the hip through changes in structure, not BMD,” stressed Dr. Bilek, of the College of Allied Health Professionals, University of Nebraska Medical Center.
 

Bone health is about more than just bone mineral density

“The key takeaway for clinicians is that bone health is about more than just density!” she noted in an email.

Current guidelines don’t recommend prescribing risedronate until a woman has overt osteoporosis, she said.

On the other hand, many studies have shown that, to be most effective, bone-loading exercises should be a lifelong habit and women should begin to do them at least during menopause and should not wait until bone loss occurs.

Other studies have shown that exercise changes bone structure (size or geometry), which improves bone strength. The current study supports both prior observations.

And exercise also improves muscle strength and decreases the risk of falls and fractures, Dr. Bilek noted.

Invited to comment, Pauline M. Camacho, MD, cochair of the task force for the American Association of Clinical Endocrinologists (AACE) guidelines for osteoporosis, noted that all three measures – pharmacotherapy, exercise, and calcium/vitamin D – are important in the successful management of osteoporosis.

This study showed that risedronate is superior to calcium/vitamin D supplementation as well as exercise for BMD and for bone turnover in these women with osteopenia, said Dr. Camacho, professor of medicine and director of the Osteoporosis and Metabolic Bone Disease Center, Loyola University Medical Center, Chicago.

“Most women with osteopenia do not receive pharmacologic therapy,” she noted, and receive it only “if there is a history of fractures or they have other features that change that diagnosis to osteoporosis.

“There is no downside to exercise, and this needs to be advised to all patients,” she said. “The other aspect of exercise that was not assessed in this study is its effect on balance. Patients who exercise will have improved balance, which should translate into fewer falls, and thus fewer fractures.”
 

How can women with osteopenia maintain bone health?

In their article, Dr. Waltman and colleagues say the Lifting Intervention for Training Muscle and Osteoporosis Rehabilitation (LIFTMOR) clinical trial is one of the first to address clinician concerns about the safety and effectiveness of exercise to improve bone health.

In that trial of 101 postmenopausal women with low bone mass, 8 months of 30-minute, twice-weekly, supervised high-intensity resistance and impact training was safe and BMD increased by 2.9% at the lumbar spine and 0.3% at the femoral neck.

“Our [HOPS] study,” Dr. Waltman and colleagues explained, “builds on the LIFTMOR clinical trial and adds further data to inform whether postmenopausal women with low bone mass can effectively maintain or even improve BMD with bone-loading exercises prior to prescriptions for medication.

“Our long-term goal is to contribute to the development of clinical practice guidelines for the prevention of fractures in postmenopausal women with low bone mass,” they said.

They randomized 276 postmenopausal women who were a mean age of 54 (range, 44-63); most were White (78%) or Hispanic (6%).

Women were excluded from the study if they had a diagnosis of osteoporosis (T-score < −2.5); had an increased risk of a major fracture or hip fracture; had been on bisphosphonates within the last 6 months; were currently on estrogen, tamoxifen, or aromatase inhibitors; had a serum vitamin D level < 10 mg/mL or > 100 mg/mL; had any conditions that prohibited prescriptions for calcium and vitamin D supplements, risedronate, or exercise; or weighed more than 300 pounds.

All women received 1,200 mg/day of calcium (from supplements or diet) and 1,000-3,000 IU/day of vitamin D supplements, based on their serum 25(OH) vitamin D levels.  

The exercise program consisted of visiting a gym three times a week for 45 minutes of bone-loading exercise – jogging with a weighted vest – and resistance exercises, which were supervised by a trainer for the first 2 weeks.

Women in the risedronate group received a 150-mg tablet of risedronate every 4 weeks.  

At baseline, 6 months, and 12 months, the women had DXA scans to determine BMD and hip structure, and had blood tests to determine levels of serum markers for bone formation (bone specific alkaline phosphatase [Alkphase B]) and bone resorption (N-terminal telopeptide [NTx]).

Compared with baseline, at 12 months, the women had the following changes in BMD at the following sites:

• Spine: +1.9%, +0.9%, and –0.4%, in the risedronate, exercise, and control groups.
• Total hip: +0.9%, +0.5%, and +0.5%, in the risedronate, exercise, and control groups.
• Femoral neck: +0.09%, –0.4%, and –0.5%, in the risedronate, exercise, and control groups.

These improvements in BMD were significantly greater in the risedronate group than in the exercise or control groups (P < .01 for both).

The decreases in serum levels of NtX and Alkphase B were also greater with risedronate than in the exercise or control groups (P < .01 for all).

The most frequent adverse effect with the calcium supplement was constipation (n = 4). Some women taking risedronate had gastrointestinal disturbances (n = 4), muscle or joint pain (n = 11), or chest pain and dizziness (n = 2). None of the women had adverse effects from vitamin D. A few women had muscle soreness from exercise that went away after the exercises were adapted. None of the women had a serious injury or fracture from exercise.

More women in the exercise group withdrew from the study (n = 20), with most citing lack of time as the reason; 13 women withdrew from the risedronate group, and 16 withdrew from the control group.

Of the 276 participants who completed the 12-month study, treatment adherence was 92% for calcium, 94% for vitamin D, 75% for risedronate, and 59% for exercise.

Exercise was associated with positive changes in intertrochanter hip structural analysis measures, which will be described in an upcoming study, Dr. Bilek said.
