Brief Summary
This study will be conducted to determine the preliminary efficacy of axatilimab in combination with ruxolitinib and to assess the contribution of axatilimab to the combination treatment effect in participants with cGVHD.
Investigators
Eligibility Criteria
Inclusion Criteria
- •≥ 12 years of age at the time of informed consent.
- •New-onset moderate or severe cGVHD, as defined by the 2014 NIH Consensus Development Project Criteria for Clinical Trials in cGVHD, requiring systemic therapy.
- •History of 1 allo-SCT (any type of stem cell donor, any conditioning regimen, and source of hematopoietic stem cells).
- •Adequate hematologic function independent of platelet transfusion and growth factors for at least 7 days prior to study entry: ANC ≥ 0.75 × 109/L and platelet count ≥ 20 × 109/L.
- •Willingness to avoid pregnancy or fathering children.
Exclusion Criteria
- •Received more than 1 prior allo-SCT. Prior autologous HCT is allowed.
- •Has overlap cGVHD, defined as simultaneous presence of features or characteristics of aGVHD in a patient with cGVHD.
- •Received previous systemic treatment for cGVHD, including systemic corticosteroids and extracorporeal photopheresis.
- •Received systemic corticosteroids within 2 weeks prior to C1D1, regardless of indication.
- •Initiated systemic treatment with CNIs or mTOR inhibitors within 2 weeks prior to C1D
- •Prior treatment with a JAK inhibitor within 8 weeks before randomization. Participants who received a JAK inhibitor for the treatment of aGVHD are eligible only if they achieved a response (CR or PR) to JAK inhibitor treatment and did not discontinue due to toxicity.
- •Evidence of relapse of the primary hematologic disease or treatment for relapse after the allo-SCT was performed, including DLIs for the treatment of molecular relapse.
- •History of acute or chronic pancreatitis.
- •History of thromboembolic events (such as deep vein thrombosis, pulmonary embolism, stroke, myocardial infarction) in the 6 months prior to study entry.
- •Active symptomatic myositis.

Outcomes
Primary Outcomes
Objective Response Rate
Time Frame: 6 months
Defined as Complete Response (CR) or Partial Response (PR) at 6 months in the absence of new systemic therapy for cGVHD. Response assessment will be based on the 2014 NIH Consensus Development Project on Criteria for Clinical Trials in cGVHD.

- Duration of Response(Up to 2 years)
- Proportion of participants who remain corticosteroid-free(4 weeks, 8 weeks and 6 months)
- Axatilimab pharmacokinetic (PK) in Plasma(Up to 2 years and 30 days)
- Proportion of participants with a ≥ 7-point improvement in modified Lee symptom scale (mLSS) score(Up to 2 years)
- OR at 12 months, defined as CR or PR at 12 months (C14D1) in the absence of new systemic therapy for cGVHD.(12 months)
- Failure-free Survival (FFS)(Up to 2 years and 30 days)
- Ruxolitinib PK in Plasma(Up to 2 years and 30 days)
- Organ-specific response in the first 6 cycles and on study, based on the 2014 NIH Consensus Development Project on Criteria for Clinical Trials in cGVHD.(Up to 2 years)
- Number of participants with Treatment-emergent Adverse Events (TEAEs)(Up to 2 years and 30 days)
