The X-NOVA study is a clinical trial for people diagnosed with moderate to severe major depressive disorder (MDD), also known as depression.

What will happen during the X-NOVA study?

Participation in the X-NOVA study lasts a total of about 14 weeks (3.5 months). Participants have a 2 in 3 chance (66.6%) to receive the study drug. The other one-third will receive a placebo (no active ingredients). Study participants can expect the following:

  1. Informed Consent Form: Review & sign the Informed Consent Form (ICF)
  2. Confirm study requirements: You will receive study assessments to confirm if you qualify for the X-NOVA study. This is called Screening and will take up to 4 weeks.
  3. Be assigned to a study group: If you qualify, you will be assigned by chance to either a study group that receives the study drug or to a study group that receives a placebo. Neither you nor the study clinic staff will know which you are receiving.
  4. Take study drug or placebo: You will be randomized to take either the study drug or placebo once daily for 6 weeks. You will visit the study clinic 5 times during this period and use a wearable device to track sleep and activity levels.
  5. Complete follow-up: After your last dose of the study drug or placebo, you will visit the study clinic 2 times over the span of 4 weeks for assessments and answer questions in a daily diary.

Participation in a clinical trial is voluntary. You can ask any questions you have and may leave the X-NOVA study at any time, for any reason.
