Open-label Study to Assess the Safety and Efficacy of TRP-8802 With Psychotherapy in Adult Participants With Fibromyalgia
Study Details
Study Description
Brief Summary
The pressing need for effective fibromyalgia (FM) treatments, the known safety of psilocybin therapy, and the mechanistic plausibility for potential benefit provide a backdrop for investigating TRP-8802 therapy as a treatment for FM. The primary objective of this study is to evaluate the clinical benefit of oral TRP-8802 in concert with psychotherapy to treat chronic pain symptoms in patients with FM.

Detailed Description
Fibromyalgia is a chronic syndrome of widespread musculoskeletal pain that often manifests with a cluster of co-occurring symptoms, including sleep disturbances, fatigue, cognitive dysfunction, and mood problems including anxiety and depression. Recent studies have provided evidence of altered central pain pathways. Current management of FM typically takes a multidimensional approach including behavioral therapy, exercise, and medication. However, current medications provide only modest benefit and carry significant side effect burden, leading many people with FM to seek other alternatives.
Psilocybin therapy (psilocybin delivered in concert with psychotherapy) may be a potentially safe and effective treatment for symptoms associated with FM. Indeed, psilocybin therapy has shown positive effects in treating cancer-related psychiatric distress, depression and anxiety, treatment-resistant depression, and nicotine or alcohol addiction. The United States Food and Drug Administration (FDA) has granted a Breakthrough Therapy designation for psilocybin in treatment-resistant depression and major depressive disorder. Psilocybin therapy is generally safe and well-tolerated when conducted under controlled conditions. While no clinical studies have explored psychedelic effects among people with FM, a recent review outlined potential mechanisms through which psychedelics could alleviate chronic pain symptoms.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Open Label Oral Psilocybin This is an open-label study, and participants who meet the inclusion and exclusion criteria will be eligible and invited to enroll. Enrolled participants are planned to receive 2 doses of TRP-8802: a 15 mg dose followed 2 weeks later by a 25 mg dose. The total planned duration of the study for an individual participant from screening to last follow-up is approximately 8 months. |
Drug: TRP-8802
Two oral doses of TRP-8802 in a capsule formulation taken approximately 2 weeks apart.
Other Names:
Behavioral: Psychotherapy
1. Pre-dose preparatory sessions; 2. Dosing day monitoring; and, 3. Post-dose integration sessions.

Age
- Participant must be 25 to 64 years of age, inclusive, at the time of signing the informed consent form.
Type of Participant and Disease Characteristics
-
Participant has had a diagnosis of FM for ≥ 3 months or has had FM symptoms for at least 1 year.
-
Participant must have a score of ≥ 13 on 2016 FM survey criteria.
-
Concurrent psychotherapy is allowed if the type and frequency of the therapy has been stable for at least 2 months prior to screening and is expected to remain stable during participation in the study.
-
Participant must be a non-smoker (tobacco).
-
Participant must be medically stable as determined by screening for medical problems via a personal interview and/or, a medical questionnaire, and an ECG, within 1 month of starting active intervention (performed during screening).
-
Participant must agree to consume approximately the same amount of caffeine-containing beverage (e.g., coffee, tea, cola) that he/she consumes on a usual morning, before arriving at the research unit on the mornings of TRP-8802 session days. If the participant does not routinely consume caffeinated beverages, he/she must agree to not do so on TRP-8802 session days.
-
Participant must agree to refrain from using any psychoactive drugs, including alcoholic beverages and nicotine, within 24 hours before and after each TRP-8802 administration. The exception is caffeine.

-
Participant must agree to not take any pro re nata (PRN) medications on the mornings of TRP-8802 sessions.
-
Participant must agree that for 7 days before each TRP-8802 session, he/she will refrain from taking any nonprescription medication, cannabis, nutritional supplement, or herbal supplement except when approved by the Principal Investigator. Exceptions will be evaluated by the Principal Investigator and will include acetaminophen, non-steroidal anti-inflammatory drugs, and common doses of vitamins and minerals.
-
Participant must have at least a high school level of education or equivalent (e.g., General Educational Development [GED] Test).

-
Sexually active male participants and/or their female partners must agree to use effective birth control for the duration of active intervention (defined as the time from the Baseline [deep phenotyping] visit until the EOT [deep phenotyping] visit) of the male participant.
