A Study to Assess 18-Methoxycoronaridine (18-MC HCl) in Healthy Volunteers

Phase 1

Completed

• Conditions: Addiction
• Interventions: Drug: 18-MC Compound

• Registration Number: NCT04292197
• Lead Sponsor: Mind Medicine, Inc.

Brief Summary

The primary objective of this study is to assess the safety and tolerability of a single day dosing and a separate multiple day dosing of 18-MC HCl administered orally, each part of the study having a different set of healthy male and female volunteers.

Detailed Description

This is a Phase 1, double-blind, randomized, placebo-controlled, single day and multiple day dosing, in healthy, non-smoking, male and female volunteers.

Part 1: Single Ascending Dose (SAD)

Seven (7) healthy male and female volunteers will be randomly assigned to receive either 18-MC HCl (n=5) or placebo (n=2) in each cohort. These volunteers will receive 18-MC HCl twice in 1 day (bid).

There are 3 phases: Screening, Enrollment and Follow-Up. All participants will be assessed for safety and tolerability for 28 days. Screening begins when a participant reports to the clinical unit (CU) for a screening visit to undergo safety and compliance assessments on this day. Participants that meet all eligibility criteria will be admitted to the CU on the day prior to receiving study drug. Enrollment begins on Day 1 where participants will receive two doses of study drug for 1 day, will be assessed for 18-MC PK up to 48 hours, and will remain admitted at the CU until Day 3, at which time they will be discharged. For follow-up the participants will return for safety and tolerability assessments at Days 7, 14, 21 and Day 28.

Part 2: Multiple Day Ascending Dose (MAD)

Seven (7) healthy male and female volunteers will be randomly assigned to receive either 18-MC HCl (n=5) or placebo (n=2) in each cohort. These volunteers will receive 18-MC HCl twice over 7 days (bid).

There are 3 phases: Screening, Enrollment and Follow-Up. All participants will be assessed for 42 days. Screening begins when a participant reports to the clinical unit (CU) for a screening visit to undergo safety and compliance assessments on this day. Participants that meet all eligibility criteria will be admitted to the CU on the day prior to receiving study drug. Enrollment begins on Day 1 where participants will receive two doses of study drug every day for 7 days, will be assessed for 18-MC PK up to 48 hours on Day 1 and Day 7, and will remain admitted at the CU until Day 9, at which time they will be discharged. For follow-up the participants will return for safety and tolerability assessments at Days 14, 21, 28, 35 and Day 42.

Arm && Interventions

Group	Intervention	Description
18-MC SAD Study	18-MC Compound	In Part 1, healthy participants will be randomized into cohorts to receive 18-MC HCl or placebo twice in 1 day.
18-MC MAD Study	18-MC Compound	In Part 2, healthy participants will be randomized into cohorts to receive 18-MC HCl or placebo twice a day for 7 consecutive days.

Primary Outcome Measures

Name	Time	Method
To assess the safety, using incidence and severity of adverse events, of a single and multiple-day dosing of 18-MC administered orally.	Up to 28 days (SAD) and 42 days (MAD)	Safety and tolerability will be assessed by the incidence and severity of adverse events (AEs). An AE was any untoward medical occurrence in a participant who received study drug. An SAE was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. Treatment-emergent are events between first dose of study drug and up to 28 days after last dose that were absent before treatment or that worsened relative to pre-treatment state. AEs included both SAEs and non-SAEs.

Secondary Outcome Measures

Name	Time	Method
Maximum Observed Plasma Concentration (Cmax)	48 post dose - Day 1 and Day 7	Blood samples for determination of study drug (18-MC) concentration parameters at various timepoints
Time to Reach Maximum Observed Plasma Concentration (Tmax)	48 hours post dose - Day 1 and Day 7	Blood samples for determination of study drug (18-MC) parameters at various timepoints
Area Under the Curve from Time Zero to Last Quantifiable Concentration (AUClast)	AUC(t0-48hr) pg*hr/mL	Blood samples for determination of study drug (18-MC) parameters at various timepoints
Terminal Elimination Half-Life (t1/2)	48 hours post dose - Day 1 and Day 7	Blood samples for determination of study drug (18-MC) concentration parameters at various timepoints
As an exploratory objective, the concentration of metabolites in plasma and urine may be determined	Up to 28 days (SAD) and 42 days (MAD)	Plasma and urine samples for determination of study drug concentrations at various timepoints
