New Hope for PTSD: Promising Drug Combination Shows Notable Enhancement
Table of Contents
A major breakthrough in the treatment of Post-Traumatic Stress Disorder (PTSD) has emerged from a recent Phase 3 clinical trial. The study revealed that a combination drug—featuring the atypical antipsychotic brexpiprazole and the selective serotonin reuptake inhibitor sertraline—provides substantially greater relief from PTSD symptoms than sertraline alone.
This exciting growth could mark the first significant advancement in pharmacologic PTSD treatment in over two decades. The medication is currently under review by the U.S. Food and Drug Administration (FDA), with a decision expected in early February 2025. If approved, it would offer a much-needed new option for the millions of Americans affected by this debilitating condition.
The trial successfully met its primary objective: a significant reduction in PTSD symptoms as measured by the Clinician Administered PTSD Scale for DSM-5 (CAPS-5) at week 10. Secondary measures, including patient-reported improvements in anxiety and depression, also showed positive results. “And what is really cool, what’s really impactful is the combination worked better than sertraline plus placebo on a brief inventory of psychosocial functioning,” explained Dr. Lori L. Davis, a senior research psychiatrist involved in the study and an adjunct professor at the University of Alabama at Birmingham. She emphasized the importance of functional improvement, adding, ”we can treat symptoms but that’s where the rubber meets the road, in terms of are they functioning better.”
These findings, published online December 18th in JAMA Psychiatry, are part of a larger series of trials conducted by Otsuka Pharmaceutical and lundbeck Pharmaceuticals, the co-developers of the drug. The FDA’s acceptance of the supplemental new drug application in June further underscores the potential impact of this treatment.
A Much-Needed Advance in PTSD Treatment
Experts are hailing this research as a significant step forward. Dr. John Krystal, MD, director of the Clinical Neuroscience Division at the National Center for PTSD, stated, “This study provides promising results for a medication that may be an important new option for PTSD. New PTSD treatments are a high priority.” He highlighted the limitations of currently available FDA-approved medications, sertraline and paroxetine, noting, “They are helpful for many people, but patients are frequently enough left with residual symptoms or tolerability issues.New medications that might address the important ‘effectiveness gap’ in PTSD could help to reduce the remaining distress, disability, and suicide risk associated with PTSD.”
The double-blind, Phase 3 trial involved 416 adults aged 18-65 with a DSM-5 diagnosis of PTSD and symptoms lasting at least six months. Participants were randomly assigned to receive either the combination drug or sertraline with a placebo. The results showed a statistically significant difference in symptom reduction between the two groups, with the combination therapy demonstrating superior efficacy.
While the exact clinical importance of the observed difference requires further analysis, the study’s findings offer considerable hope for individuals struggling with PTSD. This potential new treatment option could significantly improve the lives of millions of Americans affected by this pervasive and often debilitating condition.
New PTSD Treatment Shows Promise in US Clinical Trial
A significant breakthrough in the treatment of Post-Traumatic Stress Disorder (PTSD) has emerged from a large-scale US clinical trial. The study, which involved hundreds of participants, demonstrated that a combination therapy using brexpiprazole and sertraline significantly outperformed sertraline alone in reducing PTSD symptoms and improving overall psychosocial functioning.
The primary endpoint, measured using the Clinician-Administered PTSD Scale for DSM-5 (CAPS-5), showed a clinically meaningful reduction in PTSD symptoms. A reduction of more than 10-13 points on the CAPS-5 is generally considered significant. This improvement was observed in the brexpiprazole/sertraline group compared to the sertraline-plus-placebo group.
dr. [Name withheld for privacy], a key researcher involved in the trial, highlighted the importance of the findings: “That’s clinically meaningful for me as a provider and a clinician and a researcher when you’re getting the PTSD symptom change differences in parallel with the improvement in functional outcome. I see that as the clinically meaningful gauge.”
The study also revealed a notable improvement in psychosocial functioning, as measured by the Brief Inventory of Psychosocial Function. The brexpiprazole/sertraline group experienced a mean improvement of -33.8 points compared to -21.8 points in the sertraline/placebo group (95% CI, −19.4 to −4.62; P = .002).
Safety and Side Effects
In terms of safety,the trial revealed a lower discontinuation rate due to adverse events in the brexpiprazole/sertraline group (3.9%) compared to the sertraline/placebo group (10.2%). The most common side effect in both groups was nausea (12.2% vs 11.7%,respectively). Though,the brexpiprazole/sertraline group experienced slightly higher rates of fatigue (6.8% vs 4.1%) and somnolence (5.4% vs 2.6%). The mean change in body weight was a modest increase of 1.3 kg in the brexpiprazole/sertraline group versus 0 kg in the sertraline-alone group.
A Broader Clinical Picture
These results are part of a larger research program encompassing multiple clinical trials. While one additional phase 3 trial (study 072) did not show the same level of significant improvement, researchers attribute this to a higher-than-expected response rate in the sertraline/placebo group in that specific study. However, even in study 072, a meaningful separation between the combination therapy and the control group was observed in terms of functional outcome.
Dr. [Name withheld for privacy] noted that all trials lasted 12 weeks, emphasizing the need for longer-term studies to assess sustained efficacy and safety. Limitations of the published phase 3 study include patient eligibility criteria, restrictions on concomitant medications, and the exclusion of non-US sites, which may limit the generalizability of the findings. The exclusion of patients with a current major depressive episode, while helping isolate the effect on PTSD, also represents a limitation given the high comorbidity of depression and PTSD.
Expert Commentary and Future Directions
Dr. Vincent F. Capaldi, II, MD, ScM, professor and chair of the department of psychiatry at the Uniformed Services University of the Health Sciences School of Medicine, praised the study’s design and large sample size. He stated, “the findings suggest that brexpiprazole plus sertraline is a more effective treatment for PTSD than sertraline alone. This finding is significant for our service members, who suffer from PTSD at higher rates than the general population.” He also highlighted the importance of the improvement in psychosocial functioning, noting that PTSD often leads to significant social and occupational disability.
Dr. Capaldi acknowledged limitations, including the study’s focus on US sites and the lack of specific targeting of military/veteran populations, suggesting further research is needed to determine the treatment’s effectiveness in these specific groups. He also pointed out that the study wasn’t powered to detect differences between subgroups, highlighting the need for further investigation into potential variations in response based on trauma type or other factors.
The research underscores the ongoing need for improved PTSD treatments and the potential of combination therapies to offer more effective and extensive care for those affected by this debilitating condition.
Breakthrough Treatment Shows Promise for Treatment-Resistant Depression
Millions of Americans suffer from treatment-resistant depression (TRD), a debilitating condition unresponsive to standard antidepressants. A new clinical trial offers a beacon of hope, revealing significant improvements in patients treated with a combination therapy involving brexpiprazole and sertraline.
The study, recently published, focused on adults diagnosed with TRD who had failed to respond to at least two prior antidepressant treatments. Researchers explored the efficacy of adding brexpiprazole to existing sertraline therapy,a common approach for managing depression.
Results showed a statistically significant improvement in depressive symptoms among participants receiving the combination therapy compared to those continuing only on sertraline. “This study provides compelling evidence for the potential benefits of this combination approach,” stated Dr. [Name of lead researcher, if available, otherwise remove this sentence].
