Recruiting
1 day and over
Key Inclusion Criteria
Participants must meet all of the following criteria in order to be eligible to participate
in the study:
• Male or female ≥1 year of age.
• Had an allogeneic hematopoietic cell transplant (HCT) performed ≥21 days and ≤1 year prior to randomization.
• Myeloid engraftment confirmed, defined as an absolute neutrophil count ≥500/mm³ for 3 consecutive laboratory values obtained on different days, and platelet count >10,000/mm³ at the time of randomization.
• Diagnosed with HC based on the following criteria (all 3 criteria must be met):
• Clinical signs and/or symptoms of cystitis.
• Grade ≥3 hematuria, defined as macroscopic hematuria with visible clots.
• Viruria with ≥1 target virus (ie, BKV, JCV, AdV, CMV, EBV, and/or HHV-6).
• At least 1 identified, suitably matched posoleucel (ALVR105) cell line for infusion is available. Key Exclusion Criteria Participants who meet any of the following criteria will be excluded from participation in the study:
• Ongoing therapy with high-dose systemic corticosteroids (ie, prednisone dose >0.5 mg/kg/day or equivalent).
• Therapy with antithymocyte globulin, alemtuzumab (Campath-1H), or other immunosuppressive T cell-targeted monoclonal antibodies ≤28 days before randomization.
• Evidence of active Grade >2 acute graft versus host disease (GVHD).
• Uncontrolled or progressive bacterial or fungal infections.
• Uncontrolled or progressive viral infections not targeted by posoleucel (ALVR105).
• Uncontrolled or progressive EBV-associated post-transplant lymphoproliferative disorder.
• Known or presumed pneumonia secondary to any organism that is not considered to be well-controlled by antimicrobial therapy.
• Pregnant or lactating or planning to become pregnant. Note: Other protocol defined Inclusion/Exclusion criteria may apply.
• Male or female ≥1 year of age.
• Had an allogeneic hematopoietic cell transplant (HCT) performed ≥21 days and ≤1 year prior to randomization.
• Myeloid engraftment confirmed, defined as an absolute neutrophil count ≥500/mm³ for 3 consecutive laboratory values obtained on different days, and platelet count >10,000/mm³ at the time of randomization.
