Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of MRG-110 Following Intradermal Injection in Healthy Volunteers

May 3, 2019 updated by: miRagen Therapeutics, Inc.

A Phase 1, Randomized, Double-blind, Placebo-controlled, Single and Multiple Ascending Dose-escalation Study to Investigate the Safety, Tolerability, Pharmacokinetics, and Pharmacodynamic Activity of MRG-110 Following Local Intradermal Injection After Skin Excisional Wound Creation in Normal Healthy Volunteers

MRG-110 is intended to promote the growth of new blood vessels by inhibiting a molecule called miR-92a. MRG-110 is being studied to determine if it can accelerate healing of wounds by improving blood flow into the wound area. The primary objective of this study is to investigate the safety and tolerability of MRG-110 when injected into the skin at the site of a small skin wound in normal healthy volunteers. Another objective is to study the pharmacokinetics of MRG-110 (the movement of a drug into, through and out of the body). Participants in the clinical trial will receive either a single dose or multiple doses of MRG-110 and/or placebo. Blood samples, urine samples and skin biopsies will be collected to measure how MRG-110 is processed by the body, and how the body responds when exposed to MRG-110.

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. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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

19 years to 45 years (ADULT)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study
