A Phase 1/2a Study of WVE-007 in Adults Living With Overweight or Obesity (INLIGHT)

May 29, 2026 updated by: Wave Life Sciences USA, Inc.

A Phase 1/2a, Randomized, Double-blind, Placebo-controlled Study of Ascending Doses of WVE-007 to Evaluate Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics in Adults Living With Overweight or Obesity

The purpose of this study is to assess the safety, tolerability, pharmacokinetics and pharmacodynamics of ascending doses of WVE-007 when administered subcutaneously (SC) . Part A is a single ascending dose study in adults living with overweight and obesity. The Part B of the study is a repeat dose administration in two adult populations: Pre Type 2 diabetes (Pre T2D) and Type 2 Diabetes (T2D) in adults who are affected by obesity.

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

Exclusion Criteria: Part B

  • History of significant CV disease in the opinion of the Investigator.
  • Use of prescription medications (ie, anti-obesity or psychiatric medications) within 14 days or 7 half-lives (whichever is longer) before the first dose of study drug, except for allowed antihypertensive medications and statins.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
Time Frame
Percent change of weight (kg) from baseline
Time Frame: Day 1 through 169 Part B: Day 1 through 337
