Major Depressive Disorder Clinical Trials in Houston, TX

Major Depressive Disorder (MDD) is a mental health condition that can affect mood, energy, sleep, and overall daily functioning. It may range from moderate to severe and, in some cases, symptoms can persist despite standard treatment options.

Zillan Clinical Research is conducting the EXTEND trial, a Phase III long-term extended study that is enrolling patients who have already completed either the APPROACH or EMBRACE clinical trials and received both dose administrations of study medication in those trials.

About This Study

Exploring New Possibilities in Major Depressive Disorder Care

When depression doesnu2019t improve with standard treatment, it can continue to affect how a person feels, thinks, and functions each day. This is especially common in moderate to severe major depressive disorder (MDD) with inadequate response to antidepressants.

The current clinical depression research studies at Zillan Clinical Research are evaluating the safety and long-term efficacy of an investigational deuterated psilocin analog when used alongside ongoing antidepressant therapy and structured psychological support. Eligible participants continue on their current antidepressant therapy and receive structured psychological support and close safety monitoring throughout the study, at no cost.
