Results of a proof-of-concept, dose-finding, double-blind, placebo-controlled study of RX-10100 (Serdaxin®) in subjects with major depressive disorder.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundRX-10100 (Serdaxin®), a nonantibiotic small molecule beta-lactam compound, has shown potent antidepressant and anxiolytic activities in preclinical models. RX-10100 does not bind to the serotonin transporter or other receptors associated with monoamine activity. In microdialysis studies with rats, RX-10100 increased the release of dopamine and serotonin metabolites. A clinical proof-of-concept study was conducted to determine the clinical effectiveness of RX-10100 in treating depression.
methodsThis was a multicenter, randomized, double-blind, placebo-controlled, parallel group study of people with depression (n = 77; HAM-D-17 baseline score ≥ 20). Eligible subjects were randomly assigned to receive RX-10100 (5, 10, or 15 mg twice daily) or placebo for 8 weeks. Change from baseline in the MADRS total score was the primary endpoint.
resultsMean changes in MADRS scores were -46.0%, -37.9%, and -41.4%, for 5, 10, and 15 mg RX-10100, respectively, as compared with 43.1% for placebo. In subjects with severe depression (baseline MADRS ≥ 29; n = 28) scores improved 55.6% with 5 mg RX-10100 but only 34% with placebo (p = 0.041). In an analysis of responders (i.e., subjects with 50% change from baseline score), 64.3% of subjects treated with 5 mg RX-10100 responded. All doses of RX-10100 were well-tolerated.
conclusionIn this proof-of-concept study, RX-10100 treatment (5 mg twice daily) improved MADRS scores in subjects with severe depression. RX-10100 does not appear to have many of the typical side effects of other antidepressants. These results indicate a need for larger studies further evaluating RX-10100 at 5 mg and lower doses.
