Brief Summary:
To better understand the potential benefits of psychedelics in overeating disorders, Tryp Therapeutics will conduct a safety and feasibility clinical trial using TRP 8802 among individuals with Binge Eating Disorder. This is a single-center phase 2a open-label study to assess the safety and feasibility of a single dose of TRP 8802 in subjects with BED. Subjects will undergo screening, preparation therapy sessions, dosing, integration therapy sessions, and follow-up for 12 weeks following the dose of TRP 8802. The total participation in the study will be up to approximately 5 months.

Condition or disease Intervention/treatment Phase
Binge Eating Disorder Drug: TRYP-0082 Behavioral: Psychotherapy Phase 2

Detailed Description:

Binge eating disorder is the most common eating disorder and is associated with obesity and psychiatric comorbidities, including depression, and impulsive and compulsive disorders. Binge eating disorder is marked by severe disturbance to a person's control over their eating behaviors and high anxiety around food. Various programs using psilocybin paired with psychotherapy have shown positive effects in treating a variety of psychiatric and behavioral conditions, including cancer-related psychiatric distress, anxiety, treatment-resistant depression, and nicotine and alcohol addiction. Based on clinical precedents, relevant neuropharmacology, and mechanistic similarities, psilocybin is theorized to have the potential to be part of the treatment of overeating disorders. TRP-8802 could accomplish this by moderating overall anxiety, anxiety around food, perseveration, and repetitive and intrusive thoughts about food in people with BED.

The primary objective of this study is to:

1. Assess the safety of a single dose of TRP 8802 in participants with binge eating disorder (BED) during the TRP 8802 dosing session, and through 12 weeks following dosing (i.e., Week 14).

Estimated Primary Completion Date : June 2024
Estimated Study Completion Date : August 2025

Arm Intervention/treatment
Experimental: Open Label Oral Psilocybin Drug: TRYP-0082
A single (1) 25 mg oral dose of TRP 8802 will be administered in a carefully monitored setting following 6 to 8 hours of preparatory psychotherapy. Subjects will be in the study for 12 weeks following the dose of TRP 8802 (until Week 14), approximately 5 months from initiation of screening through the last follow-up.
Other Name: Psilocybin

Behavioral: Psychotherapy
A single (1) 25 mg oral dose of TRP 8802 will be administered in a carefully monitored setting following 6 to 8 hours of preparatory psychotherapy. Subjects will be in the study for 12 weeks following the dose of TRP 8802 (until Week 14), approximately 5 months from initiation of screening through the last follow-up.




Primary Outcome Measures :
  1. Assess the safety of a single dose of TRP 8802 in participants with BED during the TRP 8802 dosing session, and through 12 weeks following dosing [ Time Frame: 12 weeks following dosing ]
    Safety assessments will be conducted to monitor AEs, including SAEs, protocol specific safety laboratory assessments, protocol specific vital signs and other tests/questionnaires that are deemed crucial to the safety evaluation of the study. Planned timing for all safety assessments is provided in the SOA.


Secondary Outcome Measures :
  1. Evaluate the feasibility of inducing the psychedelic state with TRP 8802 in a BED population. [ Time Frame: 12 weeks following dosing ]
    Magnitude and duration of TRP 8802-induced dissociative effects in participants with BED using the MEQ30 and MRS

  2. Determine the preliminary clinical activity and the effects of TRP 8802 in conjunction with psychotherapy on the frequency of binge eating episodes in a BED population through 4 weeks following dosing (i.e., Week 6) [ Time Frame: 6 Weeks ]
    Frequency of binge eating episodes as measured by a modified Eating Questionnaire

  3. Determine the preliminary clinical activity and the effects of TRP 8802 in conjunction with psychotherapy on weight-related indicators in a BED population through 4 weeks following dosing (i.e., Week 6) [ Time Frame: 6 Weeks ]
    Waist Circumference and BMI

Criteria

Inclusion/Exclusion Criteria: Inclusion Criteria:

To participate in this study, subjects will have to meet all of the following criteria:

  1. Meet Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5) criteria for BED.
  2. Age ≥18 and ≤64 years.
  3. Provision of signed and dated informed consent form.
  4. Stated willingness to comply with all study procedures and availability for the duration of the study.
  5. Medically stable in the judgment of the Principal Investigator, as determined by screening medical, physical examination, ECG, and routine laboratory tests including blood and urinalysis.
  6. For females of reproductive potential: use of highly effective contraception for at least 1 month prior to screening and agreement to use such a method during study participation and for an additional 4 weeks following the dose of TRP 8802. Adequate birth control methods include intrauterine device; injected, implanted, intravaginal, or transdermal hormonal method; oral hormones plus a barrier contraception; abstinence; vasectomized sole partner; or double barrier contraception.
  7. For males of reproductive potential: use of condoms or other methods to ensure effective contraception with partner through 90 days post-dose.
