Oral Antidepressant Formulation

TriRima® Product Profile
Summary
TriRima® is an optimized, specific, high affinity, reversible inhibitor of monoamine oxidase-A (RIMA) potentially useful as monotherapy in the treatment of major depressive disorder. TriRima was designed and developed specifically to maximize RIMA efficacy while minimizing traditional MAOI-class tolerability issues. There is a clear unmet medical need for a robust, well tolerated alternative antidepressant with a proven mechanism of action for non-responders to SSRIs. TriRima is targeted to severe, atypical and treatment-resistant depression patients and has been tested in more than 450 subjects in Phase 1 and Phase 2 clinical trials, showing a good tolerability profile, pharmacodynamic proof of concept, and preliminary efficacy.

Mechanism of Action
Triple acting RIMAs inhibit the activity of monoamine oxidase-A, known to be elevated in major depression patients, thus preventing the breakdown and increasing the availability of the neurotransmitters serotonin, norepinephrine, and dopamine. Unlike irreversible MAO-A inhibitors, TriRima has shown no propensity to induce hypertensive crisis after ingestion of tyramine-rich food. This mechanism offers an effective, whole-brain strategy to restoring natural neurotransmitter balance to treat major depression. While increased serotonin is associated with improved mood and reduced anxiety, improved energy and motivation are associated with normalized levels of norepinephrine, addressing depression-associated fatigue and low energy. MAO-A inhibitors have been proven effective with a faster onset then SSRIs/SNRIs, but their use in the past has been limited by safety concerns. TriRima’s specific MAO-A affinity is 100x higher than moclobemide which has been launched in major markets outside the US. Due to negligible anticholinergic and antihistaminic actions, RIMAs have been shown to be better tolerated than tri- or heterocyclic antidepressants and atypical antipsychotics. Gastrointestinal side effects and sexual dysfunction have been shown to be much less frequent with RIMAs than SSRIs.

Commercial Status
TriRima is available for immediate global or regional licensing on standard commercial terms. Two robust primary market research studies have confirmed the utility and acceptance of an effective, well tolerated RIMA as an alternative to SSRIs for the treatment of severe depressive disorder. Peak sales are projected to exceed 8% of the overall prescription pharmaceutical depression market in major market areas.
