New drug vimseltinib aims to tame chronic GVHD in failed treatments
NCT ID NCT06619561
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests whether the drug vimseltinib is safe and effective for adults with moderate to severe chronic graft-versus-host disease (cGVHD) who have not improved after at least two prior treatments. About 48 participants will take vimseltinib daily for up to two years. The goal is to see if the drug can control the disease and reduce symptoms.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- vimseltinib (a drug taken by mouth)
- What this could lead to
- If successful, this could offer a new treatment option for people with chronic GVHD who have not responded to other therapies.
- What could go wrong
- This is an early-phase trial with only 48 participants, so results may not apply to everyone. The drug may cause side effects or fail to improve symptoms.

Inclusion Criteria: 1. Must be allogeneic hematopoietic stem cell transplant (HSCT) recipients with moderate to severe cGVHD requiring systemic immune suppression. a. May have persistent active acute GVHD (aGVHD) and chronic GVHD (cGVHD) manifestations (overlap syndrome). 2. Participants with active cGVHD who have received and failed at least 2 prior lines of systemic therapy. 3. Stable dose of systemic corticosteroids is permitted but not required. If being taken, participants should be on a stable dose of corticosteroids for at least 2 weeks prior to starting study drug treatment. 4. Adequate organ and bone marrow functions. 5. Participants of reproductive potential agree to follow the contraception requirements. 6. Karnofsky Performance Scale (KPS) of ≥60. Exclusion Criteria: 1. Has aGVHD without manifestations of cGVHD. 2. Prior use of colony-stimulating factor 1 receptor (CSF1R) inhibitor for cGVHD. 3. History or other evidence of severe illness, uncontrolled infection, or any other conditions that would make the participant unsuitable for the study. All wounds must be healed and free of infection or dehiscence. 4. History of malignancy except for: 1. Underlying malignancy for which the transplant was performed 2.
