Source: Clinical Study Report, data on file. 10 MIN-117 C01 (Phase 2a) : Findings

■ 24% of the patients treated with MIN-117 2.5 mg dose achieved full remission as prospectively defined (no patients in the study treated with paroxetine achieved remission)

■ Compared to placebo, the number of patients who achieved remission based on a MADRS score of < 12, on the 2.5 mg dose had an odds ratio (OR) of 2.1 by week 4 (0.5 for paroxetine), and 3.1 by week 6 (1.1 for paroxetine)

■ The 2.5 mg dose was superior to paroxetine when evaluating the rate of response based on the definition of reduction from baseline MADRS score by ≥ 50%

■ MIN-117 preserved sleep continuity and architecture and therefore is not expected to have detrimental effects on REM distribution and duration (as observed with SSRIs and SNRIs)

■ Both doses of MIN-117 demonstrated a favorable tolerability profile, and the incidence and types of side effects were comparable to placebo

■ Treatment with MIN-117 was not associated with cognitive impairment, sexual dysfunction, suicidal ideation or weight gain

MADRS Total Score change over time by modal dose

• Primary endpoint all-cause discontinuation over 6 months, seltorexant (41%) over quetiapine (47%); not powered to detect statistical significance.

• 20 mg dose of seltorexant demonstrated a larger improvement at week 24 in the MADRS (-22.7 points) than patients in other groups.

• As seen in the previous MDD trial, subjects with sleep disturbance (Insomnia Severity Index ≥15) who received the 20 mg dose of seltorexant showed greatest improvement.

■ Insomnia trial initiated Dec 2017 (clinicaltrials.gov: NCT03375203) ● Double-blind, randomized, parallel-group, active- and placebo-controlled adaptive dose-finding study ● Up to 61-day duration, including screening and follow-up ● 365 patients enrolled at 56 clinical sites in the US, Europe and Japan (~70 in each group) ● Efficacy and safety analyzed in both adults and elderly subjects randomized to receive placebo, seltorexant (5 mg, 10 mg and 20 mg), and (available under Ambien brand name)

• Primary Endpoint LPS at night 1, with adjusted 1-sided p-values <0.001.

• Mean decreases from baseline at Night 1 in LPS were 15 minutes for placebo, 30 minutes for seltorexant 5 mg, 43 minutes for seltorexant 10 mg, and 45 minutes for seltorexant 20 mg.

• Seltorexant showed superior and more sustained efficacy compared to zolpidem.

• Seltorexant showed a good safety and tolerability profile in both adult and elderly patients.
