Brief Summary:
The 2019 Severe Acute Respiratory Syndrome (SARS) is a global pandemic secondary to a novel coronavirus - SARS-CoV-2. The reported case-fatality ratio for SARS-CoV-2 in the United States is 1.8% with a current death toll of >300,000 and climbing.4 There is no accepted standard of care or FDA approved therapies for treatment of COVID-19. Virus specific cytotoxic T lymphocytes (CTLs) have become an important part of the treatment landscape for viral reactivation post hematopoietic and solid organ transplantation. Donor derived CTLs have been shown to be safe and effective against a variety of viruses including CMV, EBV, BK and adenovirus. We hypothesize that SARS-CoV-2 specific CTLs generated from a previously infected family donor will be safe and effective for treatment of COVID-19 in family members with mild to moderate disease.

Layout table for study information
Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 50 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Intervention Model Description: A run-in pilot will be done treating patients with COVID CTLs for safety. If there are no DLTs per definition in the study, study will proceed with a randomized trial of COVID CTLs + standard of care versus just standard of care alone.
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Pilot Study of SARS-CoV-2 Specific Cytotoxic T Lymphocytes (SARS-CoV-2-CTLs) for Treatment of Mild to Moderate Coronavirus Disease 2019 (COVID-19)
Actual Study Start Date : September 20, 2021
Estimated Primary Completion Date : December 31, 2024
Estimated Study Completion Date : December 31, 2025

Arm Intervention/treatment
Experimental: SARS-CoV-2 CTLS + Standard of Care
Patients will get family donor derived SARS-CoV-2 cytotoxic t-lymphocytes up to 5 times every 2 weeks along with Standard of care of COVID-19.
Other: Standard of Care
Patients will receive standard of care for COVID-19.

Biological: SARS-CoV2-CTLS
Patients may receive up to 5 CTL infusions to treat SARA-CoV-2 in combination with standard of care.

Active Comparator: Standard of Care Only
Patients will NOT received COVID CTLs but will get standard of care.
Other: Standard of Care
Patients will receive standard of care for COVID-19.

Primary Outcome Measures :
  1. Incidence of adverse events [ Time Frame: 12 weeks ]
    no adverse events will occur due to CTL infusion(s)

  • Stage III disease (severe) at the time of enrollment (see Table 1)
  • Lack of an identified eligible HLA family related donor
  • No high-risk comorbidities defined in the inclusion criteria (Section 5.1)
  • Patient with acute GVHD > grade 2 or extensive chronic GVHD at the time of enrollment

  • Patients with stage D heart failure and/or symptoms at rest are excluded
  • Renal function: patients with eGFR or CrCl <30 mL/min/1.73 m2 will be excluded from study entry.
  • Liver function: Total bilirubin > 2 mg/dl (unless Gilbert's syndrome) OR ALT/AST > 5 x ULN
  • Patients currently listed for transplant or potentially eligible to receive organ transplants are excluded from this study
  • Patient with poor performance status determined by Karnofsky (patients >16 years) or Lansky (patients ≤16 years) score ≤50%
  • Female patient of childbearing age who is pregnant or breast-feeding or not willing to use an effective method of birth control during study treatment and for at least 6 weeks after the last dose of SARS-CoV-2 CTLS.
