Brief Summary:
A study to evaluate ALVR106; an allogeneic, off-the-shelf multi-virus specific T cell therapy that targets four community acquired respiratory viruses: respiratory syncytial virus (RSV), influenza, human metapneumovirus (hMPV), and/or parainfluenza virus (PIV) following hematopoietic cell transplant (HCT)

Condition or disease Intervention/treatment Phase
Respiratory Tract Viral Infections Human Metapneumovirus (hMPV) Infection Parainfluenza (PIV) Infection Respiratory Syncytial Viral (RSV) Infection Influenza Infection Biological: ALVR106 Biological: Placebo Phase 1 Phase 2

Detailed Description:

The study hypothesis is that the administration of ALVR106, multi-virus specific T cells, plus standard of care, to post HCT patients suffering from infection with any of the four targeted viruses (RSV, influenza, hMPV, and/or PIV) will be safe and demonstrate shorter time to resolution of the respiratory viral infection (as measured by resolution of symptoms and viral load clearance in nasal swab) compared to patients treated with placebo.

This trial will consist of two parts:

Part A - Dose Escalation in Patients with Upper Respiratory Tract Infections (URTI) at High-Risk of Progression to Lower Respiratory Tract Infections (LRTI)

Part B - Recommended Phase 2 Dose (RP2D) cohort expansion in patients with URTIs at high-risk of progression to LRTIs

Primary Outcome Measures :
  1. Safety and Tolerability of ascending doses of ALVR106 assessed through Adverse Events and Clinical Laboratory tests [ Time Frame: Up to Day 365 ]
    Number (%) of patients with adverse events (AEs) according to severity, seriousness, and relationship to study drug and number (%) of patients with clinically significant change from baseline in laboratory abnormalities as characterized by type, frequency, severity (graded by CTCAE version 5.0)

  2. Change in viral load (Part B) [ Time Frame: Day 28 ]
    Change from Baseline in viral load as measured by quantitative PCR of nasal swab

Secondary Outcome Measures :
  1. Change in viral load [ Time Frame: Up to Month 6 ]
    Change from Baseline in viral load as measured by quantitative PCR of nasal swab

  2. Progression from URTI to LRTI [ Time Frame: Day 10, Day 28 ]
    Proportion of patients with progression to LRTI

  3. Identify the recommended Phase 2 (RP2D) (Part A) [ Time Frame: Day 28 ]
