Clinical Trials

Current Trials Open to Enrollment

Patients whose cases of depression are not easily treated with medication or other standard therapy may soon be helped by psychedelic substances, such as those produced by some forms of fungi.

USF Health researchers are investigating the substance psilocybin and similar psychedelics as potential treatments for treatment-resistant major depressive disorder (MDD), postpartum depression, and other depressive conditions.

Current Clinical Trials

  • ATAI ELUMINA STUDY FOR TREATMENT RESISTANT DEPRESSION

    This is a 5-month study of an investigational psychedelic medication to determine the efficacy, safety and tolerability in participants with treatment resistant depression (TRD). Participants may be eligible if they are 18-65 years of age and experiencing symptoms of treatment-resistant depression. Individuals with a co-morbid diagnosis or past history of the following are not eligible to participate – PTSD, OCD, Bipolar disorder, Schizophrenia, Schizoaffective disorder, or Borderline Personality Disorder.   Administered under supportive conditions to adult participants with treatment resistant depression. 

    KOASTAL – MAJOR DEPRESSION WITH ANHEDONIA 

    This is a two-month double-blind placebo controlled study followed by a 54-week open-label study to evaluate the efficacy and safety of NMRA-335140 in adults 18-65 years of age with Major Depression. To be eligible participants will be depressed for 1-12 months.  

    TRANSCEND – DEEP BRAIN STIMULATION FOR TREATMENT RESISTANT  DEPRESSION

    This is a 3-year study to determine the effectiveness and safety of Deep Brain Stimulation (DBS) in people with Treatment-Resistant Depression.  To be eligible participants must have failed 2-4 antidepressant medications during the current episode of depression and be 22-70 years of age.  Subjects must be good surgery candidates.  

    REUNION ADCO – ADJUSTMENT DISORDER ASSOCIATED WITH MEDICAL ILLNESS

    This is a 42-day study to determine the effectiveness and safety of an investigational psychedelic medication in the treatment of Adjustment Disorder associated with medical illnesses (Cancer, ALS, MS, PD, or IPF).  To be eligible participants must be 18-80 years old, have a greater than/equal to a 4 week history of adjustment disorder.  Eligible subjects will also have a life expectancy of at least 6 months.  Other criteria apply.    

  • MILD TO SEVERE ALZHEIMER’S DISEASE WITH AGITATION

    This is an 8 week study to evaluate an investigational drug containing THC and melatonin compared to placebo in individuals with mild to severe Alzheimer’s disease with agitation symptoms.  Participants will have a diagnosis of Alzheimer’s disease, have agitation, and have a caregiver willing to participate in the study.  There is a planned open-label extension study. 

    ALZHEIMER’S DISEASE WITH PSYCHOSIS

    A 12-week study to evaluate safety and efficacy of ITI-1284, an investigational drug, in patients with Alzheimer’s disease with psychosis.  Eligible patients will be > 55 years of age, have a diagnosis of Alzheimer’s disease, experiencing symptoms of psychosis, and have a partner or caregiver to attend study visits. 

    Healthy Volunteer Trials
    PRE-CLINICIAL ALZHEIMER’S DISEASE 

    This study is divided into two parts: Screening and Treatment.  During the Screening period – up to 125 individuals ages 65-80 years will undergo a standard memory evaluation including plasma (blood biomarkers) p-tau levels.  This is ideal for individuals who are not experiencing memory/cognitive systems but have a family history of Alzheimer’s disease. Individuals with AD biomarkers will go on to have an MRI and a PET scan.  Subjects with imaging biomarkers will be invited to continue into the treatment phase of the study.  The treatment phase involves an investigational vaccine to determine if the vaccine prevents development or progression of AD.  It is expected that only 10 individuals will progress to the vaccine phase of the study (of the 125 individuals screened).
