Cytotoxic T Lymphocytes in Treating Patients With Malignancies With BK and/or JC Virus

May 18, 2026 updated by: M.D. Anderson Cancer Center

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.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

Detailed Description

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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child
  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • 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.

Exclusion Criteria:

  • Patients receiving prednisone > 0.5 mg/kg/day at time of enrollment, or have received 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 (GVHD) grades II-IV

Time Frame: Up to 56 days
The method of Thall et al will be used to monitor the probabilities of response.

Incidence of adverse events
Time Frame: Up to day 100

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.
