Episode Synopsis
Extended-release ketamine tablets for treatment-resistant depression: a randomized placebo-controlled phase 2 trial
Nature Medicine
The safety and tolerability of racemic ketamine may be improved if given orally, as an extended-release tablet (R-107), compared with other routes of administration. In this phase 2 multicenter clinical trial, male and female adult patients with treatment-resistant major depression (TRD) and Montgomery–Asberg Depression Rating Scale (MADRS) scores ≥20 received open-label R-107 tablets 120 mg per day for 5 days and were assessed on day 8 (enrichment phase). On day 8, responders (MADRS scores ≤12 and reduction ≥50%) were randomized to receive double-blind R-107 doses of 30, 60, 120, or 180 mg, or placebo, twice weekly for 12 weeks. Nonresponders on day 8 exited the study. Tolerability was excellent, with no changes in blood pressure, minimal reports of sedation, and minimal dissociation. The most common adverse events were headache, dizziness, and anxiety. R-107 tablets were effective, safe, and well tolerated in patients with TRD, enriched for initial response to R-107 tablets.
