Aticaprant for Depression
(VENTURA-2 Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial aims to determine if aticaprant, a new potential drug, can improve symptoms of major depressive disorder (MDD) in individuals who haven't fully responded to their current antidepressants. Participants will receive either aticaprant or a placebo, alongside their existing medication, to assess which is more effective. The trial seeks individuals experiencing depression with low interest or pleasure in activities (anhedonia) who are currently taking an SSRI or SNRI medication but still struggle with symptoms. As a Phase 3 trial, this study represents the final step before FDA approval, offering participants the chance to contribute to the potential availability of a new treatment for MDD.
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.
Is there any evidence suggesting that aticaprant is likely to be safe for humans?
Studies have shown that aticaprant is generally safe when used with antidepressants like SSRIs or SNRIs. Common side effects include headaches, occurring in about 11.8% of those taking aticaprant compared to 7.1% of those on a placebo. Diarrhea was reported at similar rates in both groups. Overall, the treatment appears safe, with most side effects being mild.12345
Why do researchers think this study treatment might be promising for depression?
Researchers are excited about Aticaprant for depression because it works differently than most standard treatments. While typical antidepressants like SSRIs and SNRIs target serotonin and norepinephrine levels, Aticaprant acts on the kappa opioid receptors in the brain, which are linked to mood regulation. This unique mechanism of action could offer relief for patients who don't respond well to conventional antidepressants and may reduce depressive symptoms more effectively. Additionally, Aticaprant is designed to be taken once daily, making it a convenient option for those seeking a new approach to managing depression.
What evidence suggests that aticaprant might be an effective treatment for major depressive disorder?
Research has shown that aticaprant, one of the treatments in this trial, when combined with common antidepressants like SSRIs or SNRIs, holds promise for reducing symptoms of depression in people with major depressive disorder (MDD) who haven't improved with antidepressants alone. Studies found that aticaprant targets brain areas related to pleasure, potentially reducing feelings of anhedonia (loss of interest or pleasure). Early clinical results showed a significant decrease in depressive symptoms for those taking aticaprant compared to those taking a placebo. However, further development of aticaprant was stopped because it wasn't effective in later trials. While there were positive results early on, the treatment may not work for everyone.12456

Experimental Treatment
Placebo Group
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.
