Participant Flow

Participants were recruited at two clinical research sites in Salt Lake City, UT and Anaheim, CA between April 2018 and October 2020.

Participants underwent drug discrimination testing on Day 1 (30 mg IV methamphetamine vs normal saline). Those who reported appropriate responses on drug effects questionnaires and had no safety concerns following IV methamphetamine dosing were allowed to continue in the study. 77 subjects were enrolled, 10 discontinued or withdrew after Day 1 and 11 did not pass drug discrimination and were disqualified.

SECONDARY outcome

Timeframe: Day 1, 5, 12, 19, and 26

Population: The pharmacodynamic (PD) analysis set included 54 (96.4%) subjects for at least one time point. Two subjects were excluded after IXT-m200 dosing from the PD set due to having no measures for PD data due to early discontinuation. Other subjects were excluded for having no PD data at subsequent timepoints due to leaving the inpatient portion of the study early.

Drug effects questionnaires (visual analog scales with range from 0 (no effect) to 100 (maximum effect)) were administered following weekly doses of methamphetamine starting on Day 5, one day after IXT-m200 or placebo administration. Participants were asked questions assessing subjective effects for CRAVE over 180 minutes. Values were calculated as an area under the curve by using the trapezoidal rule; time 0 was set to 0 on the effect scale (at time of methamphetamine administration) and the area was calculated through 180 min post-dose. Lower values would indicate less drug effect (better) than higher values indicating larger drug effect (worse).

SECONDARY outcome

Timeframe: Day 1, 5, 12, 19, and 26

Population: The pharmacodynamic (PD) analysis set included 54 (96.4%) subjects for at least one time point. Two subjects were excluded after IXT-m200 dosing from the PD set due to having no measures for PD data due to early discontinuation. Other subjects were excluded for having no PD data at subsequent timepoints due to leaving the inpatient portion of the study early.

Drug effects questionnaires (visual analog scales with range from 0 (no effect) to 100 (maximum effect)) were administered following weekly doses of methamphetamine starting on Day 5, one day after IXT-m200 or placebo administration. Participants were asked questions assessing subjective effects for MORE over 180 minutes. Values were calculated as an area under the curve by using the trapezoidal rule; time 0 was set to 0 on the effect scale (at time of methamphetamine administration) and the area was calculated through 180 min post-dose. Lower values would indicate less drug effect (better) than higher values indicating larger drug effect (worse).
