Phase II Study Assessing the Effect of BK Specific CTL Lines Generated by Ex Vivo Expansion in Patients With BK Virus Infection and JC Virus Infection
This phase II trial studies how well donor cytotoxic T lymphocytes work in treating patients with malignancies with BK and/or JC virus. Cytotoxic T lymphocytes are made from donated blood cells that are grown in the laboratory and are designed to kill viruses that can cause infections in transplant patients and may be an effective treatment in patients with malignancies with BK and/or JC virus.
• Patients ≥ 2 years. English and non-English speaking patients are eligible.
• Immunocompromised patients; and/or Non-immunocompromised patients with PML/JC virus Encephalitis; and/or patients with any type of malignancies; and/or HIV/AIDs; and/or history of solid organ transplant; and/or Merkel polyoma-virus related Merkel cell tumor(s) with measurable disease on imaging per RECIST criteria.
• Patients with microscopic hematuria OR biopsy proven BK nephritis and urine or blood PCR positive for BK virus and/or JC viral encephalitis and/or JC end-organ disease and/or polyomavirus.
• Clinical status at enrollment to allow tapering of steroids to less than 0.5 mg/kg/day of prednisone.
• Patients who are currently receiving treatment with cidofovir, leflunomide, or other antiviral therapy with no response, will be eligible for CTL infusion.
• Written informed consent and/or signed assent from patient, parent or guardian. Patients with cognitive impairments are eligible.
• Negative pregnancy test in female patients of childbearing potential, defined as not post-menopausal for 12 months or no previous surgical sterilization. Women of child bearing potential must be willing to use an effective contraceptive measure while on study.
• Patients enrolled on this study may be enrolled on other IND studies at the discretion of the PI.
• Patients may be re-enrolled in the protocol should the infection re-occur, provided they meet all the other eligibility criteria at the moment of re-enrollment.
