About

This is a two-phase, randomized, double-blind, placebo-controlled, within-participant crossover study to assess the safety, tolerability, PK, and PD of five oral doses of CHI-915 versus placebo in healthy adult participants ages 18-55 years.

Laboratory results outside of the reference range deemed to be acceptable will be documented as not clinically significant at the discretion of the Investigator.
4. For women of childbearing potential, has a negative serum pregnancy test (β-human chorionic gonadotropin [hCG]) at the Screening Visit and a negative urine pregnancy test at intake to the research facility.

Participants with same sex partners or who maintain abstinence do not require contraception.
3. Person has history of diagnosis related to hepatic function and/or significantly impaired hepatic function (alanine aminotransferase [ALT] >3x upper limit of normal [ULN] or total bilirubin [TBL] >2 x ULN) OR the ALT or aspartate aminotransferase (AST) >2 x ULN and TBL >2 x ULN (or international normalized ratio [INR] >1.5).
4. Has a history of epilepsy.
5. Has used tobacco/nicotine-containing products on more than 10 occasions within 30 days of dosing with study IP or during the study.
6. Has used any prescription drugs or herbal supplements (except hormonal contraception) within 30 days prior to receiving the first dose of IP, unless approved by the Investigator and stable for at least 30 days prior to the first dose of IP through the final study visit.

10. Any clinically significant condition or abnormal finding at the Screening Visit that would, in the opinion of the Investigator, preclude study participation or interfere with evaluation of the IP.
11. Has a history of a known significant allergic condition, significant drug-related hypersensitivity, or allergic reaction to any compound or chemical class related to cannabis, including phytocannabinoids and cannabinoid analogues, or excipients utilized within the IP.
