Safety, Tolerability, and Pharmacokinetics of IXT-m200

May 31, 2023 updated by: InterveXion Therapeutics, LLC

A Phase 1, Double-Blind, Randomized, Placebo-Controlled, Single-Dose Intravenous Study to Evaluate the Safety and Pharmacokinetics of IXT-m200 in Healthy Participants

Approximately 9 participants will be enrolled in the study in a single cohort. Participants will be randomized to 3 g IXT-m200 or placebo at 7:2. Each will receive their dose as a 30-min intravenous infusion, then remain at the study site overnight to complete Day 1 and Day 2 assessments (e.g., electrocardiogram (ECG), laboratory assessments, blood draws, and vital signs). Following discharge on Day 2, participants will return to the clinic for follow-up pharmacokinetic (PK) and safety assessments on Day 8, then every 1-3 weeks thereafter until Day 127.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study
