Trial Summary

What is the purpose of this trial?

This trial is testing aticaprant to see if it can help adults with major depressive disorder and anhedonia who haven't responded well to other antidepressants. Aticaprant works by blocking certain receptors in the brain to potentially improve depressive symptoms.

Will I have to stop taking my current medications?

The trial does not require you to stop your current medications. In fact, you need to continue taking your current SSRI or SNRI antidepressant at a stable dose to participate.

How does the drug Aticaprant differ from other depression treatments?

Aticaprant is unique because it is a neurokinin-1 (NK1) receptor antagonist, which means it works by blocking specific receptors in the brain that are involved in mood regulation. This mechanism is different from most traditional antidepressants, which typically target serotonin or norepinephrine pathways. ^{1 2 3 4 5}

Treatment Details

Interventions

• Aticaprant (Other)

Trial Overview The trial is testing Aticaprant as an add-on treatment compared to a placebo. Participants will continue their current antidepressant therapy and either receive Aticaprant or a placebo to see if it better improves symptoms of depression.

Participant Groups

Group I: Aticaprant Experimental Treatment 1 Intervention

Participants will receive Aticaprant 10 milligrams (mg) tablet orally, once daily for 42 days during double-blind (DB) treatment phase in addition to their current antidepressant selective serotonin reuptake inhibitor/serotonin-norepinephrine reuptake inhibitor (SSRI/SNRI) therapy. Participants who will complete the DB treatment phase (Day 43) may be eligible to participate in a separate 52-week open-label long-term safety study 67953964MDD3003.

Group II: Placebo Placebo Group 1 Intervention

Participants will receive matching placebo tablet orally, once daily for 42 days during DB treatment phase in addition to their current antidepressant SSRI/SNRI therapy. Participants who will complete the DB treatment phase (Day 43) may be eligible to participate in a separate 52-week open-label long-term safety study 67953964MDD3003.

Findings from Research

Aprepitant, the first NK1 receptor antagonist approved for preventing chemotherapy-induced nausea and vomiting (CINV), is effective with a dosing regimen of 125 mg on day 1 and 80 mg on days 2 and 3, showing consistent plasma levels and good tolerability.

The bioavailability of aprepitant is not significantly affected by food intake, allowing it to be taken independently of meals, which simplifies its administration for patients undergoing chemotherapy.

Pharmacokinetics of aprepitant after single and multiple oral doses in healthy volunteers. Majumdar, AK., Howard, L., Goldberg, MR., et al.[2018]

In a randomized trial comparing 5 mg olanzapine and aprepitant for preventing chemotherapy-induced nausea and vomiting (CINV) in patients receiving cisplatin, both medications showed similar effectiveness in total protection rates during acute, delayed, and overall phases, with no significant differences in outcomes.

While both treatments were effective, olanzapine was associated with increased sedation as a side effect, while aprepitant led to constipation, suggesting that olanzapine may offer a cost-effective alternative for managing CINV despite its sedative effects.

In a phase 3 trial involving 196 patients receiving carboplatin, the fixed antiemetic combination NEPA (netupitant and palonosetron) demonstrated similar efficacy to the standard regimen of aprepitant, palonosetron, and dexamethasone in preventing nausea and vomiting, with complete response rates ranging from 80% to 93%.

Both NEPA and aprepitant showed comparable rates of no significant nausea, suggesting that NEPA is an effective alternative for managing chemotherapy-induced nausea and vomiting in carboplatin-treated patients, supporting the recommendation for NK1 receptor antagonists in treatment guidelines.

Aprepitant, an NK1 receptor antagonist, significantly improves the prevention of chemotherapy-induced nausea and vomiting (CINV) when added to standard antiemetic therapy, with complete response rates increasing from 43.3%-52.3% to 58.8%-71% in clinical trials involving multiple cycles of highly emetogenic chemotherapy.

The addition of aprepitant is well tolerated, with adverse events similar to standard therapy, and it effectively reduces the impact of CINV on patients' daily lives, making it a valuable option for patients undergoing chemotherapy.
