Trial of Scheduled Versus Treatment Administration of Donor-Derived Viral Specific T-cells for Viral Infections After Stem Cell Transplant

Phase 2

Recruiting

• Conditions: Allogeneic Stell Cell Transplant; Viral Infection
• Interventions: Biological: Viral Specific T-cells (VSTs) Scheduled; Biological: Viral Specific T-cells (VSTs) Treatment

• Registration Number: NCT04230356
• Lead Sponsor: Children's Hospital Medical Center, Cincinnati

Brief Summary

The purpose of this research study is to learn more about the use of viral specific T-lymphocytes (VSTs) to prevent or treat viral infections that may happen after allogeneic stem cell transplant. Allogeneic means the stem cells come from another person. VSTs are cells specially designed to fight viral infections that may happen after a stem cell transplant (SCT).

Stem cell transplant reduces the body's ability to fight infections. Viral infections are a common problem after transplant and can cause significant complications. Moreover, treatment of viral infections is expensive and time consuming, with families often administering prolonged treatments with intravenous anti-viral medications, or patients requiring prolonged admissions to the hospital. The medicines can also have side effects like damage to the kidneys or reduction in the blood counts, so in this study the investigators are trying to find a better way to treat these infections.

Recruitment & Eligibility

• Status: RECRUITING
• Sex: All
• Target Recruitment: 180

Inclusion Criteria

• Recipient must be at least 21 days after stem cell infusion
• Clinical status must allow tapering of any steroids to < 0.5mg/kg prednisone or other steroid equivalent
• No critical illness making VST infusion hazardous

Exclusion Criteria

• Active acute GVHD grades II-IV.
• Uncontrolled relapse of malignancy.
• Infusion of ATG or alemtuzumab within 2 weeks prior to VST infusion. Alemtuzumab levels will be collected in the second week following stem cell infusion in patients who received alemtuzumab as part of their conditioning regimen. The level must be less than or equal to 0.15 prior to infusion of VSTs. In patients with level greater than 0.15, alemtuzumab levels can be checked serially until a level ≤ 0.15 is obtained. They would become eligible for scheduled VST infusion at that point.

TREATMENT ARM

Inclusion Criteria:

• Blood adenovirus PCR ≥1,000
• Blood CMV PCR ≥ 500
• Blood EBV PCR ≥ 9,000
• Plasma BKV PCR >1,000
• Evidence of invasive adenovirus infection. Adenovirus infection will be defined as the presence of adenoviral positivity as detected by PCR or culture from one site such as stool or blood or urine or nasopharynx. Adenovirus disease will be defined as the presence of adenoviral positivity as detected by culture or PCR from more than 2 sites such as stool or blood or urine or nasopharynx.
• Evidence of invasive CMV infection, defined as pneumonitis, retinitis, colitis, hepatitis
• Evidence of EBV-associated lymphoproliferation (EBV-LPD) defined as proven EBV-LPD by biopsy or probable EBV-LPD defined as an elevated EBV DNA level in the blood associated with clinical symptoms (adenopathy or fever or masses on imaging) but without biopsy confirmation.
• Evidence of symptomatic BK virus infection, defined as hemorrhagic cystitis or BK nephropathy.
• No active acute GVHD grades II-IV
• No uncontrolled relapse of malignancy
• No infusion of ATG or alemtuzumab within 2 weeks of VST infusion.
• Clinical status must allow tapering of any steroids to < 0.5mg/kg prednisone or other steroid equivalent

Study & Design

• Study Type: INTERVENTIONAL
• Study Design: PARALLEL

Arm && Interventions

Group	Intervention	Description
VSTs to Prevent	Viral Specific T-cells (VSTs) Scheduled	VSTs are given through an IV infusion 21-30 days after transplant to see if the VSTs will help prevent a viral infection.
VSTs to Treat	Viral Specific T-cells (VSTs) Treatment	VSTs will be given only if a viral infection develops.

Primary Outcome Measures

Name	Time	Method
Number of Treatment Failures	21 - 100 days after transplant	Treatment failure is defined as EBV\>100,000, BKV \>100,000, CMV \>5,000 or Adv \>50,000 at any time post randomization.
