A study of 1,944 patients published in JAMA found that pharmacogenomic testing helped to minimize drug-gene interactions in patients with major depressive disorder (MDD) but had little to no effect on symptom remission at 24 weeks.

In the randomized trial, 45% of patients who received pharmacogenomic testing had no predicted drug-gene interactions. Of those who received standard of care, 18% had no such interactions.

Patients in the trial were selected from Department of Veterans Affairs (VA) medical centers from July 2017 to February 2021.

“From a VA policy perspective, I don’t think that we would say the study is robust enough that we recommend testing everybody,” said Dr. David Oslin, director of VA’s VISN 4 Mental Illness, Research, Education, and Clinical Center (MIRECC). “The results were not a slam dunk, and in fact, an important outcome of the study …

AbbVie touts positive cariprazine data in major depressive disorder

The schizophrenia and bipolar drug cariprazine (Vraylar) fared well as an adjunctive therapy in the Phase 3 3111-301-001 study involving patients with major depressive disorder (MDD).

AbbVie (NYSE:ABBV) is aiming to win a new FDA indication for the drug as an adjunctive treatment of MDD by the end of the year.

According to MedPage Today, 44% of patients in the 1.5-mg arm had at least a 50% reduction in the Montgomery-Åsberg Depression Rating Scale (MADRS) score by week 2 of treatment.

The company did not divulge significant data in a news release, stating that patients receiving a 1.5mg/day dose of the drug met the primary endpoint of statistically significant improvement based on the MADRS at week six compared to placebo. Patients receiving 3.0 mg/day per day had an improved MADRS total score, but the results were not statistically significant.

Patients in the 1.5 mg group also saw improvements in their scores on the Hamilton Depression Rating Sc…

AbbVie files supplemental New Drug Application with FDA for cariprazine

AbbVie (NYSE: ABBV) has submitted a supplemental New Drug Application (sNDA) for cariprazine (Vraylar)for major depressive disorder (MDD).

Small Pharma Inc. plans Phase 2b trial of DMT for depression

Small Pharma Inc. (TSXV:DMT) is prepping a Phase 2b clinical study to test the use of its lead candidate, SPL026, an N, N-dimethyltryptamine (DMT) in treating major depressive disorder (MDD).

DMT is present in Ayahuasca, a South American psychedelic brew.

The company has announced that it has had positive discussions with FDA regarding the planned trial.

“Importantly, the FDA’s feedback facilitates a path forward to prepare for the inclusion of U.S. sites in our Phase 2b clinical trial, which we anticipate will also be conducted across sites in Europe and the UK,” said Dr. Carol Routledge, chief medical and scientific officer of Small Pharma. “We believe that Small Pharma is conducting the first clinical trials of a DMT-assisted therapy for patients with MDD, with the potential to provide a much-needed alternative treatment for patients suffering from this debilitating condition.”

Zuranolone shows promise in treating postpartum depression

Sage Therapeutics’ (NSDQ:SAGE) and Biogen’s (NSDQ:BIIB) experimental depression drug zuranolone fared well in a Phase 3 clinical trial comparing it to placebo in the treatment of postpartum depression.

The investigational drug demonstrated meaningful improvements in terms of the baseline 17-item Hamilton Rating Scale for Depression (HAMD-17) score, the most common clinician-administered depression assessment scoring system.

After a 15-day treatment period, the zuranolone group had a mean change in HAM-D score of −17.8, resulting in a final mean score of 11.0, which is the normal range. Meanwhile, the −13.6 change in the placebo group results in a final mean score of 14.8, indicating mild-to-moderate depression.

For context, in the HAM-D system, a score of 10–13 indicates mild depression. The range of 14–17 represents mild to moderate depression. A score higher than 17 indicates severe depression.
