Brief Summary

This is a first in human, randomized, double-blind, placebo-controlled SAD (with food effect) followed by a MAD study of Trichomylin® conducted in healthy adult participants.

Detailed Description

The study is designed to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics, and food effect of Trichomylin® in healthy adult participants.

A total of up to 40 participants were planned to be enrolled into Part A and Part B of the study. Part A consisted of 3 SAD cohorts (n = 8 per cohort) and Part B consisted of 2 MAD cohorts (n = 8 per cohort). Participants underwent a Screening period beginning up to 21 days for the SAD cohorts and 28 days for the MAD cohorts prior to randomization/dose administration. The Screening period was followed by admission to the clinical research unit (CRU), pre-dose assessment, post-dose assessment(s), and a final end of study (EOS)/follow-up visit.

Safety and tolerability endpoints are to report the percentage and severity of unexpected or serious adverse events, including clinically significant vital signs, laboratory test results, physical examination, and/or reported clinical symptoms, and use of concomitant medications. Other endpoints to be assessed are neurocognitive impairment, altered state of consciousness, and overall well-being.

Other assessments include pharmacokinetic (fasted and fed states) and pharmacodynamic endpoints.

2. Must have a Body Mass Index (BMI) ≥ 18 to ≤ 32 kg/m2 with weight ≥ 50 kg at Screening;

3. Must have a negative urine drug screen at the Screening visit and the day before dosing (Day -1); one repeat urine drug may be conducted for a suspected false positive result;

4. Must be willing to abstain from the use of cannabis and other cannabinoid compounds (other than the study drug) for the duration of the study (from the time of Screening until the EOS visit);

5. Must be willing to abstain from smoking (including the use of tobacco or nicotine products and e-cigarettes) for the duration of the study (from the time of Screening until the EOS visit);

6. Must not have any hepatic and/or renal impairment as judged by the PI;

7. Must be willing and able to comply with all study procedures and be available for the duration of the study (from the time of Screening until the EOS visit);

8. Must not be currently using anti-depressants (selective serotonin reuptake inhibitors [SSRIs], monoamine oxidase inhibitors [MOAIs], serotonin-norepinephrine reuptake inhibitors [SNRIs], or tricyclic anti-depressants [TCAs]) for 14 days or 5 half-lives of the drug, whichever is longer, prior to IP administration, and for the duration of the study;

9. Must not have any current or past allergic or adverse reaction or known sensitivity to olive oil, gelatin, glycerin and titanium dioxide, or to cannabinoid-like substances (including but not limited to Dronabinol/Marinol/Nabilone/marijuana/cannabis/tetrahydrocannabinol [THC], cannabinoid oil);

10. Females must be non-pregnant and non-lactating and must use two forms ("double contraception") of acceptable, highly effective contraception from Screening and for 12 weeks following the last dose of study drug. Double contraception is defined as a condom AND one other form of the following:

1. Established hormonal contraception (with an approved oral contraceptive pill [OCP]);

2. Depot or injectable birth control;

3. A vaginal ring or an intrauterine device ([IUD], with or without hormones); OR

4. Documented evidence of surgical sterilization as a single form of birth control, at least 6 months prior to Screening (e.g., tubal ligation, hysterectomy, bilateral salpingectomy, or bilateral oophorectomy for women, OR vasectomy for men [with documented azoospermia 90 days after procedure] provided that partner is the sole sexual partner).

Women not of childbearing potential must be post-menopausal (defined as cessation or regular menstrual periods for at least 12 months). Post-menopausal status will be confirmed through testing of follicle-stimulating hormone (FSH) consistent with post-menopausal state based on lab reference ranges.

True subject abstinence for the duration of the study and 12 weeks after IP dosing is acceptable only when the subject has not been sexually active at all during their lifetime.

Periodic abstinence (e.g., calendar, ovulation, symptothermal, post-ovulation methods), withdrawal (coitus interruptus), spermicides only, and lactational amenorrhoea methods are not considered "true" abstinence and are not acceptable methods of contraception.

Female participants who are in a long-term, same-sex, monogomous relationship are not required to use contraception.

11. Male subjects of childbearing potential will be required to use condoms from Screening until 12 weeks following the last dose of the study drug and to refrain from sperm donation during the same period. Male subjects not of childbearing potential are permanently sterile by bilateral orchidectomy or vasectomy (with documented azoospermia 90 days after procedure).

Male participants who are in a long-term, same-sex, monogamous relationship are not required to use contraception.

Male subjects should be informed that if a female partner becomes pregnant while he is enrolled in the study, contact with the female partner will be attempted to request her consent to collect pregnancy outcome information.

12. Women of childbearing potential must have a negative pregnancy test at Screening and Day -1 and be willing to have additional pregnancy tests, as required, throughout the study, at the Investigator's discretion;

13. Males must not donate sperm and females must not donate ova from Screening until 12 weeks after the last dose of the study drug.

14. Must agree to adhere to the current state and national advice regarding minimizing exposure to corona virus disease of 2019 (COVID-19) from the first Screening visit until the EOS visit;

15. Must be willing and able to provide written informed consent after the nature of the study has been explained and prior to the commencement of any study procedures;

16. Must be in good physical and mental health as determined by absence of any clinically significant (in the opinion of the Investigator) abnormalities based on medical history, physical examination, vital signs, triplicate 12-lead electrocardiogram (ECG), clinical laboratory evaluations, at Screening and prior to administration of the initial dose of study drug;

17. Must be able and willing to comply with all study requirements including:

1. Confinement to the CRU prior to and during study drug administration and required follow-up periods for Part A SAD and Part B MAD

2. Refraining from using the following:

i. Any previous/current cannabis products within 2 months prior to Screening and throughout the duration of the study (from the time of Screening until the EOS visit); ii. Cannabis products (in the form of oil, vaporizer, or smoke) for the duration of the study; iii. Prescription medications 14 days prior to administration of the first dose of study drug; iv. Alcohol 48 hours prior to admission, and while confined to the CRU. In addition, participants must agree to refrain from regular use of alcohol (i.e. ˃ 10 units per week or ˃ 4 units on any given day for men and women [1 unit = 150mL of wine, 360 mL of beer, or 45 mL of 40% alcohol]) for the duration of the study; v. Recreational drugs for the duration of the study.

18. For Part A SAD, participants must not have used cannabis or cannabinoid products within 2 months prior to Screening.

Exclusion Criteria
