      Official Title

      A Phase Ib, Open-label, Randomized, Dose-finding, Multicenter Study to Evaluate the Safety, Pharmacokinetics, and Efficacy of GDC-8264 in Combination With Standard of Care in the Treatment of Acute Graft-versus-Host Disease in Patients Who Have Undergone Allogeneic Hematopoietic Stem Cell Transplantation

      Eligibility Criteria

      All Gender
      ≥18 Years Age
      No Healthy Volunteers
      Inclusion Criteria
      • Diagnosis of post-allogeneic hematopoietic stem cell transplantation (HSCT) aGVHD at screening
      • Evidence of engraftment post-transplant
      • Diagnosis of high-risk aGVHD, per refined Minnesota high-risk aGVHD criteria during screening
      • Initiation of treatment with systemic corticosteroids for aGVHD at a dose of prednisone ≥2 milligrams per kilograms per day (mg/kg/day) by orally (PO) or methylprednisolone ≥2 mg/kg/day intravenously (or equivalent) in divided doses at diagnosis and up to 3 days prior to or on the same day as initiation of GDC-8264 (Day 1), with no taper planned prior to Day 3
      Exclusion Criteria
      • Evidence of relapsed, progressing, or persistent malignancy, or treatment for relapse after transplant, or requirement for rapid immune suppression withdrawal as pre-emergent treatment of early malignancy relapse
      • Prior receipt of more than one allogeneic HSCT
      • Prior systemic treatment for aGVHD, except for the standard of care corticosteroid treatment initiated as part of this trial
      • Diagnosis of chronic GVHD or overlap syndrome
      • Uncontrolled active infection (i.e., progressive symptoms related to infection despite treatment, or persistently positive blood cultures despite treatment, or any other evidence of severe sepsis)
      • Severe organ dysfunction (e.g., acute liver failure, renal failure requiring dialysis, ventilator support, or vasopressor therapy)
      • Initiation or planned use of a marketed small molecule (excluding corticosteroids) or biologic therapy as treatment for aGVHD from the start of screening through the treatment period
