Clinical Trial: Virus-Specific Cytotoxic T-Lymphocytes (CTLs) for Adenovirus Infection Post Allogeneic Stem Cell Transplant
This study is currently recruiting patients.
|
Purpose
The purpose of this study is to find the largest safe dose of Adenovirus (AdV) specific cytotoxic T cells, to learn what the side effects are and to see whether this therapy might help prevent and treat AdV infection after transplant.

Official Title: Administration of Virus-Specific Cytotoxic T-Lymphocytes for the Prophylaxis and Therapy of Adenovirus Infection Post Allogeneic Stem Cell Transplant
Expected Total Enrollment: 20
Study start: September 2003
Cell administration will be as follows: Adenovirus specific T cells will be thawed and given by intravenous injection. This is a traditional Phase I dose escalation study of one infusion of Adenovirus-specific CTLs given to patients at risk for Adenoviral infection after matched or mismatched unrelated or matched or mismatched related donor stem cell transplant.
Three dose levels will be explored. The lowest level will be 1x dose of 1x10e7cells/m2 and the highest will be 1x dose of 1x10e8/m2. Three to six patients will be entered at each dose level (depending on toxicity) following the scheme below. This approach was successfully used in optimizing our EBV CTL infusion regime. If there are no toxicities and immunological efficacy is not seen at any dose, then the doses will be further escalated after additional local and federal approval. If the patient has Adenoviral infection, they will be eligible to receive one additional injection of CTL at the original dose.
Dose Levels and Dosing Schedule: Dose Level and CTL Dose Given from Day 30
Dose 1: 1 x 10e7/m2
Dose 2: 5 x 10e7/m2
Dose 3: 1 x 10e8/m2
Initially, Adenoviral specific Cytotoxic T Lymphocytes (AdV-CTL) will be given from day +30.
If patients develop Adenoviral infection from their 30 day or subsequent evaluations, they are eligible to receive one additional dose of CTLs.
Infusion of CTL Premedications: Patients will be premedicated with Benadryl 1mg/kg (max 50 mg) intravenously (IV) and Tylenol 10 mg/kg (max 650 mg) by mouth (PO).
Cell Administration: AdV-specific T cells will be thawed and given by intravenous injection initially from day 30 post transplant at the dose schedule outlined under Cell Administration.
Eligibility
Genders Eligible for Study: Both
Criteria
Inclusion Criteria:
- Recipients of allogeneic donor stem cell transplants at risk for Adenoviral disease.
- No evidence of GVHD > Grade II at time of enrollment.
- Life expectancy > 30 days
- No severe intercurrent infections
- Lansky/Karnofsky scores greater than or equal to 60
- Absence of severe renal disease (Creatinine > x 3 normal for age)
- Absence of severe hepatic disease (direct bilirubin > 3 mg/dl or SGOT > 500)
- Patient must be at least 30 days post transplant to be eligible to receive CTL.
- Not receiving Cidofovir
- Have not received other viral-specific CTL prophylactically within 4 weeks of receiving Adv-CTL.

Exclusion Criteria:
