All hormonal birth control must have been in use for a minimum of three months. Acceptable methods of birth control include: Abstinence (only in cases when abstinence is the usual and customary form of birth control for the participant) Hormonal contraceptives including oral contraceptives, hormone birth control patch (Ortho Evra), vaginal contraceptive ring (NuvaRing), injectable contraceptives (Depo-Provera, Lunelle), or hormone implant (Norplant System) Double-barrier method Intrauterine devices Non-heterosexual lifestyle or agrees to use contraception if planning on changing to heterosexual partner(s) Vasectomy of partner at least 6 months prior to screening Exclusion Criteria: Individuals who are pregnant, breast feeding, or planning to become pregnant during the study Allergy, sensitivity, or intolerance to the investigational product's active or inactive ingredients Regular use of medications that may have problematic interactions with psilocybin, including but not limited to dopamine agonists, MAO inhibitors, N-methyl-D-aspartate (NMDAR) antagonists, antipsychotics, and stimulants Urine drug test containing non-prescribed drugs of abuse (non-prescribed opioids, benzodiazepines, amphetamines, phencyclidine, cocaine) at screening and day of first treatment. Urine cannabinoid concentrations >50 ng/ml will suggest heavy marijuana use and will be a threshold for excluding potential subjects Having uncontrolled hypertension defined as an average systolic blood pressure ≥140 mmHg or an average diastolic blood pressure ≥90 mmHg, with at least 4 BP assessments completed. Have any of the following cardiovascular conditions: coronary artery disease, congenital long QT (time from the start of the Q wave to the end of the T wave) syndrome, cardiac hypertrophy, cardiac ischemia, congestive heart failure, myocardial infarction, tachycardia, artificial heart valve, a clinically significant screening ECG abnormality, or any other significant cardiovascular condition Significant cardiovascular event in the past 6 months. Participants with no significant cardiovascular event on stable medication may be included after assessment by the QI on a case-by-case basis Subjects with a history of seizure disorder except those who are currently receiving treatment with anti-epileptics and have been seizure-free for 3 months preceding screening or have been seizure-free for 3 years if not currently receiving anti-epileptics.

Arms of the Study

Arm 1

Arm Type

Experimental

Arm Label

Psilocybin, 1.5 mg

Arm Description

Participants will take one capsule containing 1.5 mg psilocybin with a glass of water every other day for a period of 28 days. Dosing schedule will be same for all participants with the drug taken at days 1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, and no treatment taken on alternating days. No subject shall be provided with more than five capsules (7.5mg psilocybin) at any one time to prevent diversion to the illicit market. If a dose is missed, participants are instructed to skip that dose and continue with their regularly scheduled medications. Participants are not to take >1 capsule per day.

Outcomes

Primary Outcome Measures

Study completion is defined as completing the 28-day treatment period and the final in-clinic study visit.
Compliance with study dosing regimen as measured by the Visual Analogue Scale for Dosing (VAS-D).
Participants will be monitored for compliance using electronic compliance checks via the remote patient reported outcomes system through recording consumption in the treatment diary.

Adherence with completion of diaries monitoring participant and caregiver reported outcomes.
Adherence with study requirements for patient reported and caregiver reported outcomes (i.e., diaries) will be monitored using a remote patient reported outcomes system. Adherence will be assessed by determining the number of completed patient/caregiver diaries divided by the number of diaries expected to be completed.
Adherence with completion of questionnaires monitoring participant and caregiver reported outcomes.
Adherence with study requirements for patient reported and caregiver reported outcomes (i.e., questionnaires) will be monitored using a remote patient reported outcomes system. Adherence will be assessed by determining the number of completed patient/caregiver questionnaires divided by the number of questionnaires expected to be completed.

5. Study Description

Brief Summary
Diverse symptomatology makes Fragile X Syndrome (FXS) difficult to treat, and currently there are no approved prevention or treatment methods for FXS. Current therapies, including pharmaceutical and behavioural interventions, offer a patchwork of solutions that have limited efficacy and high toxicity. The current study aims to examine psilocybin as a safe treatment alternative with the ability to improve markers of cognition, communication, mood, behavior as well as markers of neuroinflammation, serotonin levels in exosomes, and neuroplasticity at sub-hallucinogenic doses (microdosing). The overall objective of this study is to assess the feasibility of low-dose psilocybin as a therapeutic option for individuals living with FXS and to improve diagnostic parameters of FXS, as well as therapeutic responses with the use of biomarkers.
Detailed Description
A total of 10 subjects who meet all the inclusion criteria and does not meet any of the exclusion criteria will be enrolled into the study. Any subjects prematurely terminated from the study will be replaced to ensure 10 subjects complete the study. A study coordinator will contact referring clinicians, caregivers, and subjects to pre-screen for initial eligibility. Those deemed eligible will be invited for an in-person screening along with the participating caregiver. The screening visit will be approximately two hours long and will consist of informed consent, diagnostic interview, physical examination, drugs of abuse test (DOA), ECG, medical/treatment history review, and demographic forms. A pregnancy test will be performed on females of child-bearing during screening, baseline, and end-of-study visits. All eligible subjects will enter the treatment arm of the study. Subjects and caregivers will return to the clinic for a baseline visit within three weeks of their screening completion. Baseline visit will include saliva/buccal swab collection, and clinician and self-report assessments for subjects and caregivers. These assessments will include the Vineland Adaptive Behavior Scales-Third Edition (VABS-3), Clinical Global Impressions-Improvement scale (CGI-I), Visual Analog Scale-Treatment Satisfaction (VAS-TS), the Anxiety, Depression and Mood Scale (ADAMS), and the Systematic Assessment For Treatment Emergent Events (SAFTEE). Digital assessments may also be performed at the baseline visit or at home at the discretion of the qualified investigator. Digital assessments will include the NIH Toolbox Cognitive Battery Modified for Intellectual Disabilities (NIH-TCB), the Trail Making Test (TMT), and the Multifaceted Empathy Test for juveniles (MET-J). The study drug will be dispensed in blister packs to monitor adherence and improve subject compliance. Blister packs will be prepared and distributed at each subsequent visit. Subjects will return to the clinic for study visits on day 8, 15, 22, and 28 (study end date). Subjects and caregivers will complete the assessments described above. Subjects will provide additional saliva/buccal swab samples at day 15 and day 28.
