A Long-Term Extension Study of IMVT-1402 in Adult Participants With Graves' Disease (GD)

June 5, 2026 updated by: Immunovant Sciences GmbH

A Long-Term Extension Study to Assess the Efficacy, Safety, and Tolerability of IMVT-1402 in Adult Patients With Graves' Disease

This is a long-term extension study that will rollover participants completing feeder studies IMVT-1402-2502 (NCT06727604) or IMVT-1402-2503 (NCT07018323) to evaluate the efficacy and safety of IMVT-1402 in adult participants with GD. Eligible participants will be assigned to 1 of 3 study groups (Groups A, B and C) based on their GD status at the completion of their respective feeder study.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Enrolling by invitation

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Estimated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

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

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Participants who completed Study IMVT-1402-2502 or Study IMVT-1402-2503.
  • Other, more specific inclusion criteria are defined in the protocol.

Exclusion Criteria:

  • Have permanently discontinued IMP during the treatment period in the feeder study or have met study stopping criteria at any point up until the end of participation in the feeder study.

Study Plan

This section provides details of the study plan, including how the study is designed and what the study is measuring.

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.

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date.
