May 15, 2026 updated by: Viridian Therapeutics, Inc.

REVEAL-2 - A Phase 3, Randomized, Double-masked, Placebo-controlled, Efficacy, Safety, and Tolerability Study of VRDN-003 in Participants With Chronic Thyroid Eye Disease (TED)

This is a clinical trial assessing the efficacy, safety, and tolerability of an investigational drug, VRDN-003, in participants with chronic Thyroid Eye Disease (TED).

Study Overview

Status

Active, not recruiting

Conditions

Intervention / Treatment

Detailed Description

This is a randomized (meaning participants will be assigned to study arms by chance), double-masked (meaning study doctor and participant will not know which study arm participant is assigned to), placebo-controlled study that will include participants with chronic TED. The key objectives of this study are to determine if VRDN-003 is efficacious, safe and tolerable when administered as subcutaneous/SC injections every 4 weeks or every 8 weeks compared to placebo in participants with chronic TED.

Participants who do not have a meaningful response at Week 24 (irrespective of the initial treatment arm) may be eligible to receive additional subcutaneous injections of VRDN-003.

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.

  • Must not have received prior treatment with another anti-IGF-1R therapy
  • Must not have received systemic corticosteroids or steroid eye drops for any condition, including TED, or selenium within 2 weeks prior to first dose.
  • Must not have received other immunosuppressive drugs for any condition, including TED, or any other therapy for TED within 12 weeks prior to first dose
  • Must not have received an investigational agent for any condition, including TED, within 8 weeks or longer duration (depending on the type of investigational agent) prior to first dose
  • Must not have received radioactive iodine (RAI) treatment within 8 weeks prior to first dose
  • Must not have had previous orbital irradiation or decompression surgery for TED to the study eye's orbit
  • Must not have a pre-existing ophthalmic condition in the study eye which in the study doctor's opinion, would interfere with interpretation of study results

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: VRDN-003 every 4 weeks
6 subcutaneous administrations of VRDN-003
VRDN-003 is an investigational, subcutaneously administered, humanized monoclonal antibody directed against the Insulin-like Growth Factor-1 receptor (IGF-1R).
Experimental: VRDN-003 every 8 weeks
3 subcutaneous administrations of VRDN-003 and 3 subcutaneous administrations of placebo
VRDN-003 is an investigational, subcutaneously administered, humanized monoclonal antibody directed against the Insulin-like Growth Factor-1 receptor (IGF-1R).
All participants will receive the same number of injections to maintain masking. Masking will be maintained by the use of placebo injections that appear identical to VRDN-003 injections.
Placebo Comparator: Placebo every 4 weeks
6 subcutaneous administrations of placebo
All participants will receive the same number of injections to maintain masking. Masking will be maintained by the use of placebo injections that appear identical to VRDN-003 injections.
