Trial Summary

What is the purpose of this trial?

This trial is testing a new medication called NMRA 335140 to see if it can help people with Major Depressive Disorder feel less depressed. The study involves an initial evaluation and a treatment phase where participants will receive either the medication or an inactive substance. The medication likely works by changing brain chemicals that affect mood.

Do I have to stop taking my current medications for this trial?

The trial protocol does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

What data supports the idea that NMRA 335140 for Depression is an effective drug?

The available research does not provide any data supporting the effectiveness of NMRA 335140 for treating depression. The studies mentioned focus on other treatments and drugs, such as TC-5214, nitrous oxide, brexpiprazole, and ketamine, but do not include any information or results related to NMRA 335140. Therefore, there is no evidence from the provided information to suggest that NMRA 335140 is an effective treatment for depression.12345

What safety data is available for NMRA 335140 (Navacaprant) in treating depression?

The provided research does not contain specific safety data for NMRA 335140 (Navacaprant) or its other names like BTRX-140, BTRX-335140, CYM-53093, NMRA-140. The studies focus on other NMDA antagonists and their safety profiles in different contexts, such as stroke and neurosurgery patients, or as adjuncts in depression treatment. Therefore, no direct safety data for NMRA 335140 is available in the provided research.678910

Is the drug NMRA 335140 a promising treatment for depression?

Yes, NMRA 335140 is a promising drug for depression because it targets the glutamate system, which is linked to fast-acting antidepressant effects. This approach is different from traditional antidepressants and could offer quicker relief for patients.1011121314
