Additional analyses of a postmarketing trial that was required after the Food and Drug Administration’s approval of the Janus kinase inhibitor tofacitinib (Xeljanz, Xeljanz XR) has identified characteristics of older patients with rheumatoid arthritis with at least one cardiovascular risk factor who may be at higher risk for major adverse cardiovascular events (MACE) when taking the drug.

Results from the phase 3b/4 ORAL Surveillance trial presented at the virtual annual meeting of the American College of Rheumatology show that people taking tofacitinib for RA with at least one cardiovascular (CV) risk factor had a nonsignificant higher risk for MACE than did people taking tumor necrosis factor inhibitors (TNFi), with the risk from tofacitinib more pronounced in current smokers, aspirin users, people older than 65 years, and men, compared with women.

“It is the first large, randomized safety study of active RA patients with increased CV risk comparing tofacitinib to TNF inhibition,” study author Christina Charles-Schoeman, MD, said in an interview. “These data emphasize the importance of assessing baseline CV risk when treating patients with RA.” Dr. Charles-Schoeman is chief of rheumatology at the University of California, Los Angeles.

The results shed further light on the trial’s findings, which the FDA used in September 2021 to mandate boxed warnings about the risk of MI or stroke, cancer, venous thromboembolism, and death, as well as updated indications, for tofacitinib and other JAK inhibitors baricitinib (Olumiant) and upadacitinib (Rinvoq). The FDA limited all approved uses of these three medications to patients who have not responded well to TNFi to ensure their benefits outweigh their risks.

Tofacitinib is indicated for RA, psoriatic arthritis, ulcerative colitis, and polyarticular course juvenile idiopathic arthritis. Baricitinib and upadacitinib are approved only for RA.

While the overall results of the trial results show nonsignificant increased incidence rates for MACE in tofacitinib users versus TNFI users, Katherine Liao, MD, a rheumatologist at Brigham and Women’s Hospital in Boston, noted that more information is needed to determine who is at greatest risk. “Another thing to keep in mind is, while there was evidence of an elevated relative risk for MACE, compared to TNFi, the absolute risk, based on the numbers what we know so far, is small,” she said.

The trial compared two different doses of tofacitinib – 5 mg (1,455 patients) and 10 mg (n = 1,456) twice daily – and TNFi (n = 1,451) in people with moderate to severe RA over age 50. Patient characteristics were similar across all three treatment arms, Dr. Charles-Schoeman said. All patients had inadequate response to methotrexate, and about 57% in all three treatment groups were taking corticosteroids. The 10-mg tofacitinib patients switched to the 5-mg dose in February 2019 but represent the 10-mg group in the study analysis.

ORAL Surveillance demonstrated a 24% greater risk of MACE in the 5-mg tofacitinib patients and a 43% heightened risk the 10-mg group, compared with patients who received a TNFi.

The differentiating factor for MACE incidence was MI. The higher- and lower-dose tofacitinib groups had 69% and 80% greater risk for MI. While the risk for fatal MI were similar across all three treatment groups, the risk for nonfatal MI were more than doubled in the respective tofacitinib groups: hazard ratios of 2.32 and 2.08. The incidence of stroke was similar across all three arms, Dr. Charles-Schoeman said.

The study identified a number of baseline characteristics as independent overall risk factors for MACE across all treatment groups. Current smoking and aspirin use more than doubled the risk (HR, 2.18; P < .0001 and HR, 2.11; P = .004, respectively), while age greater than 65 years and male sex approached that level (HR, 1.81; P = .0011 and HR, 1.81; P = .0015) approached that level. Other factors that elevated the risk of MACE to a lesser extent were a history of diabetes, hypertension or coronary artery procedures, and a total cholesterol to HDL ratio greater than4.

Other ORAL Surveillance subanalyses and tofacitinib real-world data reported

This was one of several analyses presented at ACR 2021 that compared adverse event risks for tofacitinib versus TNFi drugs. A separate analysis of claims data from patients with RA in two U.S. insurance databases plus Medicare found a statistically nonsignificant increased risk of adverse CV outcomes (MI or stroke) with tofacitinib, compared with TNFi users, among patients who met the same inclusion and exclusion criteria of the ORAL Surveillance trial but not in a “real-world evidence” cohort of more than 102,000 patients with RA in routine care from the databases.

Two additional ORAL Surveillance analyses presented at ACR 2021 gave details about risk factors for higher rates of malignancies and venous thromboembolic events found in patients taking tofacitinib with at least one CV risk factor. As would be expected, older age (≥65 vs. 50-64 years) and current or past smoking (vs. never smoking) were independent risk factors for higher malignancy rates across all treatment arms. Pulmonary embolism events across treatment groups were independently associated with a history of venous thromboembolism, baseline use of oral contraceptives or hormone replacement therapy, baseline body mass index of at least 30 kg/m², age 65 or older, and history of hypertension.

The ORAL Surveillance findings are worth considering when determining treatments for RA patients with CV risk factors, Dr. Charles-Schoeman said. “Tofacitinib remains an effective RA treatment,” she said. “The choice of specific RA treatment for any patient remains an individual decision between the patient and physician, which is decided based on a number of different factors. This new study provides additional information regarding both tofacitinib as well as traditional CV risk factors for discussion with the patient.”

The ORAL Surveillance results may give rheumatologists reason to rethink use of tofacitinib in some patients with CV risk, said Dr. Liao of Brigham and Women’s Hospital in Boston. “Currently, we have limited data and are still awaiting a report of the full trial results,” she said in an interview. “Based on the data available, I can think of a few patients in my clinic where I would reconsider use of these drugs, i.e., history of heart attack with stable angina, especially if there are other options.” However, she noted that many patients on tofacitinib have already failed on older treatments.

These data emphasize the importance of addressing CV risk with patients, said Brittany N. Weber, MD, PhD, a cardio-rheumatologist at Brigham and Women’s Hospital who works with Dr. Liao. “It is also an opportunity to discuss modification of risk factors and to discuss primary prevention therapies, such as statin therapy, where appropriate,” she added. “Based on the individual’s cardiovascular risk, there may be a role for further risk stratification to further understand an individual’s risk, which can also inform primary prevention cardiovascular therapies and help guide these discussions.” Risk stratification could include cardiac CT for calcium scoring or cardiac coronary CT angiography for determining atherosclerotic burden.

The study was sponsored by Pfizer. Dr. Charles-Schoeman disclosed relationships with AbbVie, Bristol-Myers Squibb, Gilead Sciences, Pfizer, and Regeneron-Sanofi. Dr. Liao and Dr. Weber have no relevant disclosures.

The STEP 5 clinical trial extends favorable weight loss from 1 year out to 2 years for the glucagon-like peptide-1 (GLP-1) agonist semaglutide (Wegovy, Novo Nordisk), given as a once-weekly 2.4-mg subcutaneous injection, and some food cravings were improved in a subgroup analysis.

In another study, STEP 8, weight loss was greater at 68 weeks with semaglutide subcutaneous injection than with a 3-mg daily subcutaneous injection of another GLP-1 agonist, liraglutide (Saxenda, Novo Nordisk), approved earlier for weight loss.

Researchers presented these promising outcomes, with no new safety signals, at ObesityWeek® 2021.

However, there is more to learn about the drug class, researchers agree. Follow-up is still relatively short for a chronic disease and many patients have gastrointestinal side effects with semaglutide, one expert cautions.

The key findings were:

In STEP 5, combined with lifestyle intervention (a reduced-calorie meal plan and advice about physical activity), weekly injection of 2.4 mg semaglutide led to:

• 15.2% weight loss, compared with 2.6% weight loss with placebo at 2 years (P < .0001);
• 77% of patients losing at least 5% of their weight, compared with 34% of patients in the placebo group at 2 years (P < .0001);
• Significantly greater improvement in overall control of cravings, and craving for savory foods, in a subset of patients, versus placebo, but questionnaire scores for positive mood and craving for sweet foods were similar in both groups.
• In STEP 8, mean body weight at 68 weeks was 15.8% lower with 2.4 mg/week subcutaneous semaglutide plus lifestyle changes versus 6.4% lower with 3.0 mg/day subcutaneous liraglutide plus lifestyle changes (P < .001).

Can treat to a target weight-loss range

The undiminished weight loss efficacy in the 2-year data for STEP 5 “portends well,” said W. Timothy Garvey, MD, following his presentation of the results.

Weight loss plus reduced cravings

In another presentation, Sean Wharton, MD, PharmD, said, “In adults with overweight or obesity, substantial weight loss with semaglutide 2.4 mg was accompanied by short- and long-term improvements in control of eating.”

Clinically meaningful weight loss

When presenting the STEP 8 findings, Domenica M. Rubino, MD, said: “Participants were significantly more likely to achieve clinically meaningful weight loss thresholds with semaglutide 2.4 mg versus liraglutide 3.0 mg, accompanied by greater improvements in cardiometabolic risk factors.”

For example, patients can have better mobility, which is important for quality of life, Dr. Rubino, director of the Washington Center for Weight Management and Research, Arlington, Virginia, noted. 

A smaller percentage of patients respond to liraglutide, she added. Clinicians need to individualize treatment.

When asked, “How do you choose which medical therapy?” Dr. Rubino responded: “We sit and talk.” Finding the medical therapy that fits the patient depends on things such as the patient’s insurance coverage and ability to tolerate side effects such as dehydration, diarrhea, and nausea.   

When asked, “How do you switch from liraglutide to semaglutide?” she noted that there are no current guidelines for this. “You have to be careful. Start on the lowest dose of Wegovy. Be cautious, conservative.”  
 

Still early days, caveats remain

“The STEP trials as a group appear to be making the case that obesity may now be considered a medically manageable disease, based on the experience with semaglutide,” Julie R. Ingelfinger, MD, who was not involved with the research, commented in an email.

STEP 5 weight loss efficacy and safety at 2 years

Garvey reported that STEP 5 was a phase 3b trial that randomized 304 adults in the United States, Canada, Hungary, Italy, and Spain, who were 18 years and older, with a body mass index (BMI) ≥27 kg/m² with at least one weight-related comorbidity (hypertension, dyslipidemia, obstructive sleep apnea, or cardiovascular disease) or a BMI ≥30 kg/m², without type 2 diabetes, to receive semaglutide or placebo plus lifestyle intervention.

Most participants were women (78%) and White (93%). On average, they were 47 years old, weighed 106 kg (223.7 pounds), had a BMI of 38.5 kg/m², a waist circumference of 115.7 cm (45.6 inches), and an A1c of 5.7%.

A total of 87% of patients in the semaglutide group and 73% of patients in the placebo group completed the trial.

At 104 weeks, participants were more likely to lose ≥10%, ≥15%, and ≥20% of body weight with semaglutide versus placebo (61.8% vs. 13.3%, 52.1% vs. 7.0%, and 36.1% vs. 2.3%, respectively; P < .0001 for all).

Patients in the semaglutide group had greater health improvements in cardiovascular risk factors (waist circumference, systolic and diastolic blood pressure, and C-reactive protein) and metabolic risk factors (A1c, fasting plasma glucose, fasting serum insulin, and triglycerides) than those in the placebo group (P < .05 for all).

Safety and tolerability were consistent with adverse events seen with this drug class, with no new safety signals.
 

Control of eating questionnaire findings at 2 years in STEP 5

Dr. Wharton and colleagues assessed changes in responses to the Control of Eating questionnaire at baseline and at 20, 52, and 104 weeks in patients from the U.S. and Canada in the STEP 5 trial (88 patients in the semaglutide group and 86 patients in the placebo group).

The questionnaire consisted of 19 questions grouped into four categories: control of food cravings, craving for savory foods (salty and spicy, dairy, or starchy foods), craving for sweet foods (chocolate, sweet foods, or fruit/fruit juice), and positive mood.

At week 104, patients in the semaglutide group had significantly greater improvements in scores for craving for salty and spicy, dairy, and starchy foods, and resisting cravings.
 

Semaglutide versus liraglutide, 68-week efficacy and safety in STEP 8

STEP 8 randomized 338 U.S. adults without diabetes and a BMI of ≥27 kg/m² plus one or more weight-related comorbidities or a BMI of ≥30 kg/m² 3:1 to semaglutide 2.4 mg once weekly (n = 126) or matching placebo, or 3:1 liraglutide 3.0 mg once daily (n = 127) or matching placebo, plus lifestyle intervention.

Most participants were women (78%) and were a mean age of 49, had a mean body weight of 104.5 kg, and had a mean BMI of 37.5 kg/m².

In STEP 8, more participants achieved ≥10%, ≥15%, and ≥20% weight loss with semaglutide than with liraglutide (70.9% vs. 25.6%, 55.6% vs. 12.0%, and 38.5% vs. 6.0%, respectively; P < .001 for all odds ratios).

Semaglutide improved waist circumference, A1c, and C-reactive protein versus liraglutide (unadjusted P < .001 for all).

Gastrointestinal adverse events were reported by 84% and 83% of participants receiving semaglutide and liraglutide, respectively. Most events were mild/moderate and transient, with prevalence declining over time.

Fewer participants stopped treatment due to adverse events with semaglutide than liraglutide (3.2% vs. 12.6%).

Dr. Garvey has reported serving as a site principal investigator for multicentered clinical trials sponsored by his university and funded by Eli Lilly, Novo Nordisk, and Pfizer. Dr. Wharton has reported financial ties to Novo Nordisk, Bausch Health Canada, Eli Lily, and Boehringer Ingelheim Canada. Dr. Rubino has reported ties to Boehringer Ingelheim and AstraZeneca. Dr. Ingelfinger has reported no relevant financial relationships.

Garvey reported that STEP 5 was a phase 3b trial that randomized 304 adults in the United States, Canada, Hungary, Italy, and Spain, who were 18 years and older, with a body mass index (BMI) ≥27 kg/m² with at least one weight-related comorbidity (hypertension, dyslipidemia, obstructive sleep apnea, or cardiovascular disease) or a BMI ≥30 kg/m², without type 2 diabetes, to receive semaglutide or placebo plus lifestyle intervention.

Most participants were women (78%) and White (93%). On average, they were 47 years old, weighed 106 kg (223.7 pounds), had a BMI of 38.5 kg/m², a waist circumference of 115.7 cm (45.6 inches), and an A1c of 5.7%.

A total of 87% of patients in the semaglutide group and 73% of patients in the placebo group completed the trial.

At 104 weeks, participants were more likely to lose ≥10%, ≥15%, and ≥20% of body weight with semaglutide versus placebo (61.8% vs. 13.3%, 52.1% vs. 7.0%, and 36.1% vs. 2.3%, respectively; P < .0001 for all).

Patients in the semaglutide group had greater health improvements in cardiovascular risk factors (waist circumference, systolic and diastolic blood pressure, and C-reactive protein) and metabolic risk factors (A1c, fasting plasma glucose, fasting serum insulin, and triglycerides) than those in the placebo group (P < .05 for all).

Safety and tolerability were consistent with adverse events seen with this drug class, with no new safety signals.
 

Control of eating questionnaire findings at 2 years in STEP 5

Dr. Wharton and colleagues assessed changes in responses to the Control of Eating questionnaire at baseline and at 20, 52, and 104 weeks in patients from the U.S. and Canada in the STEP 5 trial (88 patients in the semaglutide group and 86 patients in the placebo group).

The questionnaire consisted of 19 questions grouped into four categories: control of food cravings, craving for savory foods (salty and spicy, dairy, or starchy foods), craving for sweet foods (chocolate, sweet foods, or fruit/fruit juice), and positive mood.

At week 104, patients in the semaglutide group had significantly greater improvements in scores for craving for salty and spicy, dairy, and starchy foods, and resisting cravings.
 

Semaglutide versus liraglutide, 68-week efficacy and safety in STEP 8

STEP 8 randomized 338 U.S. adults without diabetes and a BMI of ≥27 kg/m² plus one or more weight-related comorbidities or a BMI of ≥30 kg/m² 3:1 to semaglutide 2.4 mg once weekly (n = 126) or matching placebo, or 3:1 liraglutide 3.0 mg once daily (n = 127) or matching placebo, plus lifestyle intervention.

Most participants were women (78%) and were a mean age of 49, had a mean body weight of 104.5 kg, and had a mean BMI of 37.5 kg/m².

In STEP 8, more participants achieved ≥10%, ≥15%, and ≥20% weight loss with semaglutide than with liraglutide (70.9% vs. 25.6%, 55.6% vs. 12.0%, and 38.5% vs. 6.0%, respectively; P < .001 for all odds ratios).

Semaglutide improved waist circumference, A1c, and C-reactive protein versus liraglutide (unadjusted P < .001 for all).

Gastrointestinal adverse events were reported by 84% and 83% of participants receiving semaglutide and liraglutide, respectively. Most events were mild/moderate and transient, with prevalence declining over time.

Fewer participants stopped treatment due to adverse events with semaglutide than liraglutide (3.2% vs. 12.6%).

Dr. Garvey has reported serving as a site principal investigator for multicentered clinical trials sponsored by his university and funded by Eli Lilly, Novo Nordisk, and Pfizer. Dr. Wharton has reported financial ties to Novo Nordisk, Bausch Health Canada, Eli Lily, and Boehringer Ingelheim Canada. Dr. Rubino has reported ties to Boehringer Ingelheim and AstraZeneca. Dr. Ingelfinger has reported no relevant financial relationships.

The STEP 5 clinical trial extends favorable weight loss from 1 year out to 2 years for the glucagon-like peptide-1 (GLP-1) agonist semaglutide (Wegovy, Novo Nordisk), given as a once-weekly 2.4-mg subcutaneous injection, and some food cravings were improved in a subgroup analysis.

In another study, STEP 8, weight loss was greater at 68 weeks with semaglutide subcutaneous injection than with a 3-mg daily subcutaneous injection of another GLP-1 agonist, liraglutide (Saxenda, Novo Nordisk), approved earlier for weight loss.

Researchers presented these promising outcomes, with no new safety signals, at ObesityWeek® 2021.

However, there is more to learn about the drug class, researchers agree. Follow-up is still relatively short for a chronic disease and many patients have gastrointestinal side effects with semaglutide, one expert cautions.

The key findings were:

In STEP 5, combined with lifestyle intervention (a reduced-calorie meal plan and advice about physical activity), weekly injection of 2.4 mg semaglutide led to:

• 15.2% weight loss, compared with 2.6% weight loss with placebo at 2 years (P < .0001);
• 77% of patients losing at least 5% of their weight, compared with 34% of patients in the placebo group at 2 years (P < .0001);
• Significantly greater improvement in overall control of cravings, and craving for savory foods, in a subset of patients, versus placebo, but questionnaire scores for positive mood and craving for sweet foods were similar in both groups.
• In STEP 8, mean body weight at 68 weeks was 15.8% lower with 2.4 mg/week subcutaneous semaglutide plus lifestyle changes versus 6.4% lower with 3.0 mg/day subcutaneous liraglutide plus lifestyle changes (P < .001).

Can treat to a target weight-loss range

The undiminished weight loss efficacy in the 2-year data for STEP 5 “portends well,” said W. Timothy Garvey, MD, following his presentation of the results.

Weight loss plus reduced cravings

In another presentation, Sean Wharton, MD, PharmD, said, “In adults with overweight or obesity, substantial weight loss with semaglutide 2.4 mg was accompanied by short- and long-term improvements in control of eating.”

Clinically meaningful weight loss

When presenting the STEP 8 findings, Domenica M. Rubino, MD, said: “Participants were significantly more likely to achieve clinically meaningful weight loss thresholds with semaglutide 2.4 mg versus liraglutide 3.0 mg, accompanied by greater improvements in cardiometabolic risk factors.”

For example, patients can have better mobility, which is important for quality of life, Dr. Rubino, director of the Washington Center for Weight Management and Research, Arlington, Virginia, noted. 

A smaller percentage of patients respond to liraglutide, she added. Clinicians need to individualize treatment.

When asked, “How do you choose which medical therapy?” Dr. Rubino responded: “We sit and talk.” Finding the medical therapy that fits the patient depends on things such as the patient’s insurance coverage and ability to tolerate side effects such as dehydration, diarrhea, and nausea.   

When asked, “How do you switch from liraglutide to semaglutide?” she noted that there are no current guidelines for this. “You have to be careful. Start on the lowest dose of Wegovy. Be cautious, conservative.”  
 

Still early days, caveats remain

A single infusion of ketamine rapidly improves distorted thinking and reasoning to reduce suicidal thoughts, independent of the drug’s effect on severe depression, new research shows.

“Previously it was shown that ketamine rapidly improved depression and that explained part of the rapid improvement in suicidal ideation,” senior author J. John Mann, MD, with Columbia University, New York, said in an interview.

“What was unclear was what else changed that could decrease suicidal ideation and the risk for suicidal behavior. This study identifies a second new domain of improvement – namely rapid improvement in several cognitive functions that can potentially reduce suicide risk,” said Dr. Mann.

The study was published online Nov. 2, 2021, in the Journal of Clinical Psychiatry.
 

Boosts cognitive function

A total of 78 adults with major depressive disorder and clinically significant suicidal ideation underwent neuropsychological testing before, and 1 day after, double-blind treatment with a single intravenous infusion of ketamine or midazolam.

“Ketamine produced rapid improvement in suicidal ideation and mood” compared with midazolam, the authors reported.

Ketamine was linked to specific improvement in reaction time and cognitive control/interference processing – a measure that has been associated with previous suicide attempt in depression.

A subgroup of patients whose suicidal ideation did not remit on midazolam were later treated with unblinded ketamine and retested. In these individuals, reaction time and cognitive control/interference processing also improved relative to preketamine assessments.

Neurocognitive improvement, however, was not correlated with changes in depression, suicidal thinking, or general mood, the researchers noted.

Nonetheless, they say ketamine had a “positive therapeutic effect” on neurocognition 1 day after treatment on at least one measure associated with suicidal behavior in the context of depression.

The results suggest “additional independent therapeutic effects for ketamine in the treatment of depressed patients at risk for suicidal behavior,” they wrote.

“Ketamine modulates many neurotransmitter systems including glutamate transmission which is crucial for learning and memory. It increases the number of synapses or connections between neurons. These effects are fundamental to cognition and are logical explanations of the beneficial effects observed in this study,” Dr. Mann said in an interview.

“Our study helped us gain a better understanding of how ketamine works in the brain and how quickly it can improve distorted thinking. Being able to think more clearly can make someone feel less suicidal,” study investigator Ravi. N. Shah, MD, chief innovation officer, Columbia Psychiatry, said in a news release.
 

Important research with caveats

In a comment, James Murrough, MD, PhD, director of the Depression and Anxiety Center for Discovery and Treatment at Mount Sinai in New York, said the study is important and “adds to a growing understanding of how ketamine affects brain systems and thinking in the context of depression and suicide risk.”

“One reason this study is significant is that prior studies have shown that ketamine can have harmful effects on cognitive functioning in the context of ketamine misuse and exposures to high doses for long periods of time,” Dr. Murrough, who wasn’t involved in the study, said in an interview.

“In contrast in this study, a single low-dose treatment of ketamine can have the opposite effects, actually boosting some markers of cognitive functioning, at least in the short-term,” he noted.

Dr. Murrough said one caveat to the study is that it only examined the effect of ketamine on cognition once, 1 day after a single treatment.

“While this is an important initial observation, we don’t yet have any understanding of how persistent this effect on cognition is, or how this observed change may be related to any benefit ketamine may have on depression or suicide risk,” Dr. Murrough said.

“In fact, the researchers found that there was no association between change in cognitive functioning following ketamine and change in depression or suicidal thinking. The patients who showed improved cognitive function following ketamine did not differ in terms of mood or suicide risk compared to patients who did not show an improvement in cognition,” Dr. Murrough noted.

“This raises the important question of what is the relevance of change in cognition to the potential benefits of ketamine. This is an important area and should be the focus of future research in order to improve outcomes for patients with depression and who are at risk for suicide,” he added.

Also weighing in, Roger S. McIntyre, MD, professor of psychiatry and pharmacology and head of the mood disorders psychopharmacology unit, University of Toronto, said the study is “very interesting and in keeping” with some previous work that he and his colleagues have done showing that ketamine “seems to benefit aspects of cognition which is a core element in depression.”

“It’s a testable hypothesis that the improvement in cognition now being reported and replicated could play some role in the improved quality of life and functioning with this treatment and as well reduce reducing suicide,” said Dr. McIntyre.

Treating elevated low-density lipoprotein cholesterol (LDL-C) in adults younger than 40 with statins is highly cost-effective in men, and intermediately cost-effective in women, a new report suggests.

Time to relax the age 40 threshold

The U.S. Preventive Services Task Force and the American College of Cardiology/American Heart Association should emphasize lifetime risk of elevated cholesterol, Paul A. Heidenreich, MD, MS, Stanford University School of Medicine, California, and colleagues write in an accompanying editorial.

“In addition to calculating 10-year risk, we should calculate years of life lost (or QALYs lost) from unhealthy LDL-C levels, and both lifestyle and pharmacologic treatment should be considered to treat high LDL-C in adults regardless of age. We also need to communicate that the mantra ‘lower is better’ applies not only to a single measurement but to lifetime exposure to LDL-C,” the editorialists write.

“I think treatment should be earlier than age 40,” Dr. Heidenreich said in an interview.

“Part of the reason that 40 was chosen as a threshold was because everyone looked at 10-year, or even 20-year risk, and thought there was no reason to worry until you get older. It’s interesting that we never accepted that with high blood pressure. But more and more, we are learning that it is a lifelong process,” he said.

“Statins are getting less and less expensive, and their safety is more and more established with every decade that goes by. I definitely agree with this paper that it would actually make sense to be starting much earlier for those with elevated CVD risk from their high cholesterol.”

The study was supported by the U.S. National Heart, Lung, and Blood Institute (NHLBI), the Medical Research Council, Swindon, U.K. Dr. Moran and Dr. Heidenreich have disclosed no relevant financial relationships.

LAS VEGAS – Risankizumab (Skyrizi, AbbVie) provides early and lasting benefits for patients with Crohn’s disease, phase 3 trials indicate.

Based on these and other recent findings, the drug could be used as a first-line treatment and even displace ustekinumab (Stelara, Janssen), which itself was approved by the Food and Drug Administration for Crohn’s disease in 2016, according to David Rubin, MD, the Joseph B. Kirsner Professor of Medicine at the University of Chicago.

“The drug works fast,” Dr. Rubin said in an interview. “If you start this therapy in patients with moderate to severe Crohn’s disease, they’re likely to feel better within the first few weeks.”

Dr. Rubin presented the findings on the drug’s early onset at the annual meeting of the American College of Gastroenterology. A related trial presented at the meeting showed the drug continuing to perform well up to 52 weeks.

Advances in immunomodulation have allowed drug companies to feed multiple new therapies into the pipeline for Crohn’s disease and related conditions in recent years, giving hope to the many patients who have not been able to benefit from older classes of drugs, such as biologics.

A humanized immunoglobulin G1 (IgG1) monoclonal antibody, risankizumab blocks interleukin (IL) 23 by binding to its p19 subunit. IL-23 is a cytokine implicated in several chronic immune disorders, including Crohn’s disease and psoriasis. Researchers hope that risankizumab will prove more selective, with a better safety profile, than previous drugs in its class. The FDA approved risankizumab in April 2019 for the treatment of moderate to severe plaque psoriasis.
 

MOTIVATE and ADVANCE studies

The two induction trials for Crohn’s disease enrolled slightly different populations.

The MOTIVATE study enrolled patients who had responded inadequately or were intolerant to biologic therapy. In this trial, the investigators assigned 205 patients to 1,200 mg of risankizumab, 206 patients to 600 mg of risankizumab, and 207 patients to placebo.

The ADVANCE study enrolled patients who had responded inadequately or could not tolerate either biologic or conventional therapy. In this trial, investigators randomly assigned 372 patients to 1,200 mg of risankizumab, 373 patients to 600 mg of risankizumab, and 186 patients to placebo.

In both trials, intravenous injections were given at weeks 0, 4, and 8.

The researchers defined a Crohn’s Disease Activity Index (CDAI) clinical remission as a score less than 150. They defined a Stool Frequency and Abdominal Pain Score (SF/APS) clinical remission as a soft stool frequency of no more than 2.8, and an abdominal pain score of no more than 1 and not worse than baseline.

A CDAI clinical response was at least a 100-point decrease from baseline. The SF/APS enhanced clinical response was at least a 60% decrease in average daily stool frequency or at least a 35% decrease in average daily abdominal pain, with both not worse than baseline.

At 4 weeks, the researchers found that the percentage of patients who achieved CDAI clinical remission in both risankizumab groups of both studies was greater than in the placebo group. The difference was statistically significant (P ≤ .01 in ADVANCE and P ≤ .05 in MOTIVATE), and it continued to grow at 8 weeks and 12 weeks.

By 12 weeks in the ADVANCE trial, according to a press release from AbbVie, 45% of patients on the 600-mg dose of risankizumab and 42% on the 1,200-mg dose of risankizumab had achieved CDAI clinical remission, compared with 25% of those on placebo, which was statistically significant (P < .001). For the MOTIVATE trial, the results were significantly better for patients in the risankizumab groups than for those in the placebo group.

In both trials, the treated groups continued to improve faster than the placebo groups through 12 weeks. Improvements in SF/APS enhanced clinical response largely paralleled those for CDAI clinical remission.

“It did show very good results,” session moderator Jonathan Leighton, MD, professor of medicine and chair of the division of gastroenterology at Mayo Clinic in Phoenix, Ariz., said in an interview with Medscape Medical News. “But basically, it’s so early that we don’t have all the data.” In particular, he would have liked to see whether patients responded to the drug before week 4.
 

FORTIFY study

In FORTIFY, the maintenance trial that followed, the researchers rerandomized those patients who had responded to risankizumab into three groups. Two groups received subcutaneous injections of risankizumab, with 179 patients getting 360 mg and another 179 patients getting 180 mg. The placebo group included the remaining 184 patients.

At week 52, 40.9% of patients in the placebo group were in clinical remission, compared with 52.2% in the 360-mg group and 55.4% in the 180-mg group, which was statistically significant (P = .005 for 360 mg, and P = .003 for 180 mg.)

“It showed us that [risankizumab] could achieve deep remission, which means patients achieving remission endoscopically in combination with clinical remission,” the presenter, Marla Dubinsky, MD, professor of pediatrics and medicine in the division of pediatric gastroenterology at Icahn School of Medicine at Mount Sinai in New York, said in an interview.

Over the 52 weeks, deep remission and endoscopic remission rates increased in the 360-mg group, held steady in the 180-mg group, and decreased in the placebo group. Mean fecal calprotectin and C-reactive protein levels decreased in the risankizumab groups and increased in the placebo group.

There were more total treatment-emergent adverse events per 100 patient-years in the placebo group (339.7) than in the 360-mg group (269.3) or the 180-mg group (283.5). The same difference between groups was true of severe treatment-emergent adverse events. Serious events and events leading to discontinuation were similar in the three groups.

The glucagon-like peptide-1 (GLP-1) receptor agonist liraglutide (Saxenda, Novo Nordisk) was safe and effective for treating weight regain after Roux-en-Y gastric bypass (RYGB), in a randomized controlled trial.

That is, 132 patients who had lost at least 25% of their initial weight after RYGB and then gained at least 10% back were randomized 2:1 to receive liraglutide plus frequent lifestyle advice from a registered dietitian or lifestyle advice alone.

After a year, 69%, 48%, and 24% of patients who had received liraglutide lost at least 5%, 10%, and 15% of their study entry weight, respectively. In contrast, only 5% of patients in the control group lost at least 5% of their weight and none lost at least 10% of their weight.

“Liraglutide 3.0 mg/day, with lifestyle modification, was significantly more effective than placebo in treating weight regain after RYGB without increased risk of serious adverse events,” Holly F. Lofton, MD, summarized this week in an oral session at ObesityWeek®, the annual meeting of The Obesity Society.

Dr. Lofton, a clinical associate professor of surgery and medicine, and director, weight management program, NYU, Langone Health, explained to this news organization that she initiated the study after attending a “packed” session about post bariatric surgery weight regain at a prior American Society of Metabolic and Bariatric Surgery conference.

“The lecturers recommended conservative measures (such as reiterating the diet recommendations, exercise, [and] counseling), and revisional surgeries,” she said in an email, but at the time “there was no literature that provided direction on which pharmacotherapies are best for this population.”

It was known that decreases in endogenous GLP-1 levels coincide with weight regain, and liraglutide (Saxenda) was the only GLP-1 agonist approved for chronic weight management at the time, so she devised the current study protocol.

The findings are especially helpful for patients who are not candidates for bariatric surgery revisions, she noted. Further research is needed to investigate the effect of newer GLP-1 agonists, such as semaglutide (Wegovy), on weight regain following different types of bariatric surgery.

Asked to comment, Wendy C. King, PhD, who was not involved with this research, said that more than two-thirds of patients treated with 3 mg/day subcutaneous liraglutide injections in the current study lost at least 5% of their initial weight a year later, and 20% of them attained a weight as low as, or lower than, their lowest weight after bariatric surgery (nadir weight).

“The fact that both groups received lifestyle counseling from registered dietitians for just over a year, but only patients in the liraglutide group lost weight, on average, speaks to the difficulty of losing weight following weight regain post–bariatric surgery,” added Dr. King, an associate professor of epidemiology at the University of Pittsburgh, Pennsylvania.

This study “provides data that may help clinicians and patients understand the potential effect of adding liraglutide 3.0 mg/day to their weight loss efforts,” she told this news organization in an email.

However, “given that 42% of those on liraglutide reported gastrointestinal-related side effects, patients should also be counseled on this potential outcome and given suggestions for how to minimize such side effects,” Dr. King suggested.
 

Weight regain common, repeat surgery entails risk

Weight regain is common even years after bariatric surgery. Repeat surgery entails some risk, and lifestyle approaches alone are rarely successful in reversing weight regain, Dr. Lofton told the audience.

The researchers enrolled 132 adults who had a mean weight of 134 kg (295 pounds) when they underwent RYGB, and who lost at least 25% of their initial weight (mean weight loss of 38%) after the surgery, but who also regained at least 10% of their initial weight.

At enrollment of the current study (baseline), the patients had had RYGB 18 months to 10 years earlier (mean 5.7 years earlier) and now had a mean weight of 99 kg (218 pounds) and a mean BMI of 35.6 kg/m². None of the patients had diabetes.  

The patients were randomized to receive liraglutide (n = 89, 84% women) or placebo (n = 43, 88% women) for 56 weeks.

They were a mean age of 48 years, and about 59% were White and 25% were Black.

All patients had clinic visits every 3 months where they received lifestyle counseling from a registered dietitian.

At 12 months, patients in the liraglutide group had lost a mean of 8.8% of their baseline weight, whereas those in the placebo group had gained a mean of 1.48% of their baseline weight.

There were no significant between-group differences in cardiometabolic variables.

None of the patients in the control group attained a weight that was as low as their nadir weight after RYGB.

The rates of nausea (25%), constipation (16%), and abdominal pain (10%) in the liraglutide group were higher than in the placebo group (7%, 14%, and 5%, respectively) but similar to rates of gastrointestinal side effects in other trials of this agent.

Dr. Lofton has disclosed receiving consulting fees and being on a speaker bureau for Novo Nordisk and receiving research funds from Boehringer Ingelheim, Eli Lilly, and Novo Nordisk. Dr. King has reported no relevant financial relationships.

“The fact that both groups received lifestyle counseling from registered dietitians for just over a year, but only patients in the liraglutide group lost weight, on average, speaks to the difficulty of losing weight following weight regain post–bariatric surgery,” added Dr. King, an associate professor of epidemiology at the University of Pittsburgh, Pennsylvania.

This study “provides data that may help clinicians and patients understand the potential effect of adding liraglutide 3.0 mg/day to their weight loss efforts,” she told this news organization in an email.

However, “given that 42% of those on liraglutide reported gastrointestinal-related side effects, patients should also be counseled on this potential outcome and given suggestions for how to minimize such side effects,” Dr. King suggested.
 

Weight regain common, repeat surgery entails risk

Weight regain is common even years after bariatric surgery. Repeat surgery entails some risk, and lifestyle approaches alone are rarely successful in reversing weight regain, Dr. Lofton told the audience.

The researchers enrolled 132 adults who had a mean weight of 134 kg (295 pounds) when they underwent RYGB, and who lost at least 25% of their initial weight (mean weight loss of 38%) after the surgery, but who also regained at least 10% of their initial weight.

At enrollment of the current study (baseline), the patients had had RYGB 18 months to 10 years earlier (mean 5.7 years earlier) and now had a mean weight of 99 kg (218 pounds) and a mean BMI of 35.6 kg/m². None of the patients had diabetes.  

The patients were randomized to receive liraglutide (n = 89, 84% women) or placebo (n = 43, 88% women) for 56 weeks.

They were a mean age of 48 years, and about 59% were White and 25% were Black.

All patients had clinic visits every 3 months where they received lifestyle counseling from a registered dietitian.

At 12 months, patients in the liraglutide group had lost a mean of 8.8% of their baseline weight, whereas those in the placebo group had gained a mean of 1.48% of their baseline weight.

There were no significant between-group differences in cardiometabolic variables.

None of the patients in the control group attained a weight that was as low as their nadir weight after RYGB.

The rates of nausea (25%), constipation (16%), and abdominal pain (10%) in the liraglutide group were higher than in the placebo group (7%, 14%, and 5%, respectively) but similar to rates of gastrointestinal side effects in other trials of this agent.

Dr. Lofton has disclosed receiving consulting fees and being on a speaker bureau for Novo Nordisk and receiving research funds from Boehringer Ingelheim, Eli Lilly, and Novo Nordisk. Dr. King has reported no relevant financial relationships.

The use of statins by patients with rheumatoid arthritis appears to provide an overall net benefit on cardiovascular disease outcomes that outweighs the risk of type 2 diabetes mellitus (T2DM) seen with the drugs in the general population, according to evidence from a cohort study of more than 16,000 people in the United Kingdom that was presented at the virtual annual meeting of the American College of Rheumatology.

“Our study emphasizes that RA patients should be assessed for statin initiation to improve CVD risk,” lead study author Gulsen Ozen, MD, a third-year resident at the University of Nebraska, Omaha, said in an interview. Because the risk of T2DM with statin use is no worse in patients with RA than in the general population, statin initiation “is actually a great opportunity to address the risk factors for T2DM such as activity and exercise, obesity and weight loss, and [use of glucocorticoids], which have other important health effects,” she said.

“Also, importantly, even if [patients] develop T2DM, statins still work on CVD and mortality outcomes as in patients without diabetes,” Dr. Ozen added. “Given all, the benefits of statins way outweigh the hazards.”

Dr. Ozen said this was the first large cohort study to evaluate CVD mortality and T2DM risks with statins in patients with RA, a claim with which rheumatologist Elena Myasoedova, MD, PhD, of the Mayo Clinic in Rochester, Minn., concurred.

Dr. Myasoedova, professor of rheumatology and epidemiology at Mayo, said in an interview that the study was “methodologically rigorous” using time-conditional propensity score (TCPS) matching and a prevalent new-user design, “thus addressing the immortal time bias” found in the design of studies in which patients enter a cohort but do not start a treatment before developing the outcome of interest and are assigned to the untreated group or when the period of delay from when patients enter the cohort to when they are treated is excluded from the analysis. An earlier study from the same authors did not use TCPS matching, she said.

“The study findings suggest that patients with RA can benefit from statin use in terms of CVD outcomes and mortality but physicians should use vigilance regarding increased T2DM risk and discuss this possibility with patients,” Dr. Myasoedova said. “Identifying patients who are at higher risk of developing T2DM after statin initiation would be important to personalize the approach to statin therapy.”
 

Study details

The study accessed records from the U.K. Clinical Practice Research Datalink and linked Hospital Episode Statistics and Office of National Statistics databases. It analyzed adult patients with RA who were diagnosed during 1989-2018 in two cohorts: One for CVD and all-cause mortality, consisting of 1,768 statin initiators and 3,528 TCPS-matched nonusers; and a T2DM cohort with 3,608 statin initiators and 7,208 TCPS-matched nonusers.

In the entire cohort, statin use was associated with a 32% reduction in CV events (composite endpoint of the nonfatal or fatal MI, stroke, hospitalized heart failure, or CVD mortality), a 54% reduction in all-cause mortality, and a 33% increase in risk for T2DM, Dr. Ozen said. Results were similar in both sexes, although CV event reduction with statins in men did not reach statistical significance, likely because of a smaller sample size, she said.

Patients with and without a history of CVD had a similar reduction in CV events and all-cause mortality, and risk for T2DM increased with statins, but the latter reached statistical significance only in patients without a history of CVD, Dr. Ozen said.

Patients with RA who are at risk for T2DM and who are taking statins require blood glucose monitoring, which is typically done in patients with RA on disease-modifying antirheumatic drugs, and hemoglobin A1c testing when glucose levels are impaired, she said. “Any concerns for T2DM would be also communicated by the primary care providers of the patients to initiate further assessment and management,” she said.

But Dr. Ozen noted that confusion exists among primary care physicians and rheumatologists about who’s responsible for prescribing statins in these patients. “I would like to remind you that instead of assigning this role to a certain specialty, just good communication could improve this care gap of statin underutilization in RA,” she said. “Also, for rheumatologists, given that all-cause mortality reduction with statins was as high as CV event reduction, statins may be reducing other causes of mortality through improving disease activity.”

Bristol-Myers Squibb provided funding for the study. Dr. Ozen and Dr. Myasoedova have no relevant disclosures.

Early trials are under way to test medicinal mushrooms and Chinese herbs to treat COVID-19 patients with mild to moderate symptoms.

The U.S. Food and Drug Administration (FDA) approved the MACH-19 trials (the acronym for Mushrooms and Chinese Herbs for COVID-19) after researchers applied for approval in April.

The first two phase 1 randomized, double-blind, placebo-controlled trials have begun at UCLA and the University of California San Diego to treat COVID-19 patients quarantining at home with mild to moderate symptoms. A third trial is investigating the use of medicinal mushrooms as an adjuvant to COVID-19 vaccines.

The researchers have also launched a fourth trial testing the mushrooms against placebo as an adjunct to a COVID booster shot. It looks at the effect in people who have comorbidities that would reduce their vaccine response. An article in JAMA  described the trials.

The two mushroom varieties being tested — turkey tail and agarikon — are available as over-the-counter supplements, according to the report. They are a separate class from hallucinogenic or “magic” mushrooms being tested for other uses in medicine.

“They are not even as psychoactive as a cup of tea,” Gordon Saxe, MD, PhD, MPH, principal investigator for the MACH-19 trials, told this news organization.

For each of the MACH-19 treatment trials, researchers plan to recruit 66 people who are quarantined at home with mild to moderate COVID-19 symptoms. Participants will be randomly assigned either to receive the mushroom combination, the Chinese herbs, or a placebo for 2 weeks, according to the JAMA paper.

D. Craig Hopp, PhD, deputy director of the division of extramural research at the National Center for Complementary and Integrative Health (NCCIH), told JAMA in an interview that he was “mildly concerned” about using mushrooms to treat people with active SARS-CoV-2 infection.

“We know that a cytokine storm poses the greatest risk of COVID mortality, not the virus itself,” Dr. Hopp said. “The danger is that an immune-stimulating agent like mushrooms might supercharge an individual’s immune response, leading to a cytokine storm.”

Stephen Wilson, PhD, an immunologist who consulted on the trials when he was chief operating officer of the La Jolla Institute for Immunology, says in the JAMA article that a cytokine storm is unlikely for these patients because the mushroom components “don’t mimic inflammatory cytokines.” Dr. Wilson is now chief innovations officer at Statera Biopharma.

“We think the mushrooms increase the number of immunologic opportunities to better see and respond to a specific threat. In the doses used, the mushrooms perturb the immune system in a good way but fall far short of driving hyper or sustained inflammation,” Dr. Wilson said.

Dr. Saxe said the FDA process was extensive and rigorous and FDA investigators also asked about potential cytokine storms before approving the trials. Cytokine storm is not an issue with a healthy response, Dr. Saxe pointed out. It’s a response that’s not balanced or modulated.

“Mushrooms are immunomodulatory,” he said. “In some ways they very specifically enhance immunity. In other ways they calm down overimmunity.” Dr. Saxe noted that they did a sentinel study for the storm potential “and we didn’t see any evidence for it.”

“Not a crazy concept”

Dr. Saxe pointed out that one of the mushrooms in the combo they use — agarikon — was used to treat pulmonary infections 2,300 years ago.

“Hippocrates, the father of western medicine, used mushrooms,” he said. “Penicillin comes from fungi. It’s not a crazy concept. Most people who oppose this or are skeptics — to some extent, it’s a lack of information.”

Dr. Saxe explained that there are receptors on human cells that bind specific mushroom polysaccharides.

“There’s a hand-in-glove fit there,” Dr. Saxe said, and that’s one way mushrooms can modulate immune cell behavior, which could have an effect against SARS-CoV-2.

Daniel Kuritzkes, MD, chief of the division of infectious diseases at Brigham and Women’s Hospital in Boston, who was not part of the study, told this news organization that he wasn’t surprised the FDA approved moving forward with the trials.

“As long as you can demonstrate that there is a rationale for doing the trial and that you have some safety data or a plan to collect safety data, they are fairly liberal about doing early-phase studies. It would be a much different issue, I think, if they were proposing to do a study for actual licensing or approval of a drug,” Dr. Kuritzkes said.

As yet unanswered, he noted, is which component of the mushrooms or herbs is having the effect. It will be a challenge, he said, to know from one batch of the compound to the next that you have the same amount of material and that it’s going to have the same potency among lots.

Another challenge is how the mushrooms and herbs might interact with other therapies, Dr. Kuritzkes said.

He gave the example of St. John’s Wort, which has been problematic in HIV treatment.

“If someone is on certain HIV medicines and they also are taking St. John’s Wort, they basically are causing the liver to eat up the HIV drug and they don’t get adequate levels of the drug,” he said.

Though there are many challenges ahead, Dr. Kuritzkes acknowledged, but added that “this is a great starting point.”

He, too, pointed out that many traditional medicines were discovered from plants.

“The most famous of these is quinine, which came from cinchona bark that was used to treat malaria.” Dr. Kuritzkes said. Digitalis, often used to treat heart failure, comes from the fox glove plant, he added.

He said it’s important to remember that “people shouldn’t be seeking experimental therapies in place of proven therapies, they should be thinking of them in addition to proven therapies.»

Certain antihypertensive medications, particularly diuretics, are linked to lower Alzheimer’s disease neuropathology and other brain disease processes, new research shows.

Investigators found that use of any antihypertensive was associated with an 18% decrease in Alzheimer’s disease neuropathology, a 22% decrease in Lewy bodies, and a 40% decrease in TAR DNA-binding protein 43 (TDP-43), a protein relevant to several neurodegenerative diseases. Diuretics in particular appear to be driving the association.

Although diuretics might be a better option for preventing brain neuropathology, it’s too early to make firm recommendations solely on the basis of these results as to what blood pressure–lowering agent to prescribe a particular patient, said study investigator Ahmad Sajjadi, MD, assistant professor of neurology, University of California, Irvine.

“This is early stages and preliminary results,” said Dr. Sajjadi, “but it’s food for thought.”

The findings were presented at the 2021 annual meeting of the American Neurological Association.
 

Autopsy data

The study included 3,315 individuals who had donated their brains to research. The National Alzheimer’s Coordinating Center maintains a database that includes data from 32 Alzheimer’s disease research centers in the United States. Participants in the study must have visited one of these centers within 4 years of death. Each person whose brain was included in the study underwent two or more BP measurements on at least 50% of visits.

The mean age at death was 81.7 years, and the mean time between last visit and death was 13.1 months. About 44.4% of participants were women, 57.0% had at least a college degree, and 84.7% had cognitive impairment.

Researchers defined hypertension as systolic BP of at least 130 mm Hg, diastolic BP of at least 80 mm Hg, mean arterial pressure of at least 100 mm Hg, and pulse pressure of at least 60 mm Hg.

Antihypertensive medications that were evaluated included antiadrenergic agents, ACE inhibitors, angiotensin II receptor blockers, beta blockers, calcium channel blockers, diuretics, vasodilators, and combination therapies.

The investigators assessed the number of neuropathologies. In addition to Alzheimer’s disease neuropathology, which included amyloid-beta, tau, Lewy bodies, and TDP-43, they also assessed for atherosclerosis, arteriolosclerosis, cerebral amyloid angiopathy, frontotemporal lobar degeneration, and hippocampal sclerosis.

Results showed that use of any antihypertensive was associated with a lower likelihood of Alzheimer’s disease neuropathology (odds ratio, 0.822), Lewy bodies (OR, 0.786), and TDP 43 (OR, 0.597). Use of antihypertensives was also associated with increased odds of atherosclerosis (OR, 1.217) (all P < .5.)

The study showed that hypertensive systolic BP was associated with higher odds of Alzheimer’s disease neuropathology (OR, 1.28; P < .5).

Differences by drug type

Results differed in accordance with antihypertensive class. Angiotensin II receptor blockers decreased the odds of Alzheimer’s disease neuropathology by 40% (OR, 0.60; P < .5). Diuretics decreased the odds of Alzheimer’s disease by 36% (OR, 0.64; P < .001) and of hippocampal sclerosis by 32% (OR, 0.68; P < .5).

“We see diuretics are a main driver, especially for lower odds of Alzheimer’s disease and lower odds of hippocampal sclerosis,” said lead author Hanna L. Nguyen, a first-year medical student at the University of California, Irvine.

The results indicate that it is the medications, not BP levels, that account for these associations, she added.

One potential mechanism linking antihypertensives to brain pathology is that with these agents, BP is maintained in the target zone. Blood pressure that’s too high can damage blood vessels, whereas BP that’s too low may result in less than adequate perfusion, said Ms. Nguyen.

These medications may also alter pathways leading to degeneration and could, for example, affect the apo E mechanism of Alzheimer’s disease, she added.

The researchers plan to conduct subset analyses using apo E genetic status and age of death.

Although this is a “massive database,” it has limitations. For example, said Dr. Sajjadi, it does not reveal when patients started taking BP medication, how long they had been taking it, or why.

“We don’t know the exact the reason they were taking these medications. Was it just hypertension, or did they also have heart disease, stroke, a kidney problem, or was there another explanation,” he said.

Following the study presentation, session comoderator Krish Sathian, MBBS, PhD, professor of neurology, neural, and behavioral sciences, and psychology and director of the Neuroscience Institute, Penn State University, Hershey, called this work “fascinating. It provides a lot of data that really touches on everyday practice,” inasmuch as clinicians often prescribe antihypertensive medications and see patients with these kinds of brain disorders.

The investigators and Dr. Sathian reported no relevant financial relationships.

Many years ago, drug development in psychiatry turned to control of specific symptoms across disorders rather than within disorders, but regulatory agencies are still not yet on board, according to an expert psychopharmacologist outlining the ongoing evolution at the virtual Psychopharmacology Update presented by Current Psychiatry and the American Academy of Clinical Psychiatrists, sponsored by Medscape Live.

If this reorientation is going to lead to the broad indications the newer drugs likely deserve, which is control of specific types of symptoms regardless of the diagnosis, “we have to move the [Food and Drug Administration] along,” said Stephen M. Stahl, MD, PhD, chairman of the Neuroscience Institute and an adjunct professor of psychiatry at the University of California, San Diego.

On the side of drug development and clinical practice, the reorientation has already taken place. Dr. Stahl described numerous brain circuits known to produce symptoms when function is altered that are now treatment targets. This includes the ventral medial prefrontal cortex where deficient information processing leads to depression and the orbital frontal cortex where altered function leads to impulsivity.

“It is not like each part of the brain does a little bit of everything. Rather, each part of the brain has an assignment and duty and function,” Dr. Stahl explained. By addressing the disturbed signaling in brain circuits that lead to depression, impulsivity, agitation, or other symptoms, there is an opportunity for control, regardless of the psychiatric diagnosis with which the symptom is associated.

For example, Dr. Stahl predicted that pimavanserin, a highly selective 5-HT_2A inverse agonist that is already approved for psychosis in Parkinson’s disease, is now likely to be approved for psychosis associated with other conditions on the basis of recent positive clinical studies in these other disorders.

Brexpiprazole, a serotonin-dopamine activity modulator already known to be useful for control of the agitation characteristic of schizophrenia, is now showing the same type of activity against agitation when it is associated with Alzheimer’s disease. Again, Dr. Stahl thinks this drug is on course for an indication across diseases once studies are conducted in each disease individually.

Another drug being evaluated for agitation, the N-methyl-D-aspartate receptor antagonist dextromethorphan bupropion, is also being tested for treatment of symptoms across multiple disorders, he reported.

However, the FDA has so far taken the position that each drug must be tested separately for a given symptom in each disorder for which it is being considered despite the underlying premise that it is the symptom, not the disease, that is important.

“Psychiatric disorders are syndromes, categorized by a collection of symptoms defined descriptively but not neurobiologically,” Dr. Stahl said. Unlike physiological diseases where symptoms, like a fever or abdominal cramps, are the product of a disease, psychiatric symptoms are the disease and a fundamental target – regardless of the DSM-based diagnosis.

To some degree, the symptoms of psychiatric disorders have always been the focus of treatment, but a pivot toward developing therapies that will control a symptom regardless of the underlying diagnosis is an important conceptual change. It is being made possible by advances in the detail with which the neuropathology of these symptoms is understood .

“By my count, 79 symptoms are described in DSM-5, but they are spread across hundreds of syndromes because they are grouped together in different ways,” Dr. Stahl observed.

He noted that clinicians make a diagnosis on the basis symptom groupings, but their interventions are selected to address the manifestations of the disease, not the disease itself.

“If you are a real psychopharmacologist treating real patients, you are treating the specific symptoms of the specific patient,” according to Dr. Stahl.

So far, the FDA has not made this leap, insisting on trials in these categorical disorders rather than permitting trial designs that allow benefit to be demonstrated against a symptom regardless of the syndrome with which it is associated.

Of egregious examples, Dr. Stahl recounted a recent trial of a 5-HT₂ antagonist that looked so promising against psychosis in Alzheimer’s disease that the trialists enrolled patients with psychosis regardless of type of dementia, such as vascular dementia and Lewy body disease. The efficacy was impressive.

“It worked so well that they stopped the trial, but the FDA declined to approve it,” Dr. Stahl recounted. Despite clear evidence of benefit, the regulators insisted that the investigators needed to show a significant benefit in each condition individually.

While the trial investigators acknowledged that there was not enough power in the trial to show a statistically significant benefit in each category, they argued that the overall benefit and the consistent response across categories required them to stop the trial for ethical reasons.

“That’s your problem, the FDA said to the investigators,” according to Dr. Stahl.

The failure of the FDA to recognize the efficacy of psychopharmacologic therapies across symptoms regardless of the associated disease is a failure to stay current with an important evolution in medicine, Dr. Stahl indicated.

“What we have come to understand is the neurobiology of any given symptom is likely to be the same across disorders,” he said.
 

Agency’s arbitrary decisions cited

“I completely agree with Dr. Stahl,” said Henry A. Nasrallah, MD, professor of psychiatry, neurology, and neuroscience, University of Cincinnati.

In addition to the fact that symptoms are present across multiple categories, many patients manifest multiple symptoms at one time, Dr. Nasrallah pointed out. For neurodegenerative disorders associated with psychosis, depression, anxiety, aggression, and other symptoms, it is already well known that the heterogeneous symptoms “cannot be treated with a single drug,” he said. Rather different drugs targeting each symptom individually is essential for effective management.

Dr. Nasrallah, who chaired the Psychopharmacology Update meeting, has made this point many times in the past, including in his role as the editor of Current Psychiatry. In one editorial 10 years ago, he wrote that “it makes little sense for the FDA to mandate that a drug must work for a DSM diagnosis instead of specific symptoms.”

“The FDA must update its old policy, which has led to the widespread off-label use of psychiatric drugs, an artificial concept, simply because the FDA arbitrarily decided a long time ago that new drugs must be approved for a specific DSM diagnosis,” Dr. Nasrallah said.

Dr. Stahl reported financial relationships with more than 20 pharmaceutical companies, including those that are involved in the development of drugs included in his talk. Medscape Live and this news organization are owned by the same parent company.
