Acquired Immunodeficiency Syndrome BK Virus Infection Human Immunodeficiency Virus JC Virus Infection Malignant Neoplasm Merkel Cell Carcinoma Merkel Cell Polyomavirus Infection Viral Encephalitis | Biological: Allogeneic BK-specific Cytotoxic T-lymphocytes Other: Laboratory Biomarker Analysis | Phase 2 |
PRIMARY OBJECTIVE:
I. To assess the efficacy, feasibility and safety of administering most closely human leukocyte antigen (HLA)-matched BK specific cytotoxic T lymphocyte (CTL) lines (BK-CTLs) generated by ex vivo expansion to mediate antiviral activity in patients with any type of malignancies, and/or human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDs), and/or history of solid organ transplant with BK and JC infections.
SECONDARY OBJECTIVE:
I. To assess the persistence of the administered BK-CTLs generated by ex vivo expansion in patients with any type of malignancies, and/or HIV/AIDs, and/or history of solid organ transplant with BK and JC infections.
OUTLINE:
Patients receive allogeneic BK-specific cytotoxic T-lymphocytes intravenously (IV) over 30 minutes. Patients achieving partial response, stable disease, or progressive disease are eligible for 7 additional infusions of CTL occurring at least 2 weeks after the previous CTL infusion if they meet the eligibility criteria for subsequent therapy.
After completion of study treatment, patients are followed up periodically for 12 months.

Experimental: Treatment (BK-specific cytotoxic T lymphocytes)
Patients receive allogeneic BK-specific cytotoxic T-lymphocytes IV over 30 minutes. Patients achieving partial response, stable disease, or progressive disease are eligible for 19 additional infusions of CTL occurring at least 2 weeks after the previous CTL infusion if they meet the eligibility criteria for subsequent therapy.

- Response, defined as response (R) = (best response [R1] or second best response [R2]) [ Time Frame: Up to 56 days ]The method of Thall et al will be used to monitor the probabilities of response.
- Incidence of acute graft-versus-host disease (GVHD) [ Time Frame: Within 28 days of the last dose of cytotoxic T lymphocytes (CTLs) ]The method of Thall et al will be used to monitor the probabilities of grade 3 or 4 GVHD.
- Incidence of adverse events [ Time Frame: Up to day 100 ]Will be continuously monitored.
- Overall survival [ Time Frame: Up to 12 months ]Each outcome will be evaluated by tabulation and by fitting a Bayesian statistical regression model for binary outcomes as a function of covar. Unadjusted event time distributions will be estimated using the Kaplan-Meier method.
- Glomerular filtration rate [ Time Frame: Up to 12 months ]Each outcome will be evaluated by tabulation and by fitting a Bayesian statistical regression model for binary outcomes as a function of covar. Unadjusted event time distributions will be estimated using the Kaplan-Meier method.

Ages Eligible for Study: | Child, Adult, Older Adult |
Sexes Eligible for Study: | All |
Accepts Healthy Volunteers: | No |
Inclusion Criteria:
- 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 Response Evaluation Criteria in Solid Tumors (RECIST) criteria
- Patients with microscopic hematuria OR biopsy proven BK nephritis and urine or blood polymerase chain reaction (PCR) positive for BK virus and/or JC viral encephalitis
- 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
- Once patients have completed 6-week safety and efficacy assessments after completion of the last anti-BK CTL infusion, patients will be eligible for enrollment on other supportive care protocols
- Written informed consent from patient and/or signed assent from patient, parent or guardian
- 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
Exclusion Criteria:
- Patients receiving prednisone > 0.5 mg/kg/day at time of enrollment, or have received anti-thymocyte globulin (ATG) within 14 days or have received donor lymphocyte infusion (DLI) or Campath within 28 days of enrollment
- Patients with other uncontrolled infections (except HIV/AIDS); for bacterial infections, patients must be receiving definitive therapy and have no signs of progressing infection for 72 hours prior to enrollment; for fungal infections patients must be receiving definitive systemic anti-fungal therapy and have no signs of progressing infection for 1 week prior to enrollment; progressing infection is defined as hemodynamic instability attributable to sepsis or new symptoms, worsening physical signs or radiographic findings attributable to infection; persisting fever without other signs or symptoms will not be interpreted as progressing infection
- Patients with active acute graft-versus-host disease (GVHD) grades II-IV
