Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Number of Participants With Treatment-emergent Adverse Events (TEAEs) (Part A) | Day 1 up to 12 months | A TEAE was defined as an adverse event (AE) with a start date and time on or after the first dose of study treatment. A serious AE (SAE) was an AE that met at least one of the following serious criteria: fatal, life-threatening, requires in-patient hospitalization or prolongation of existing hospitalization; resulted in persistent or significant disability/incapacity; was a congenital anomaly/birth defect; or other important medical event. TEAEs of special interest (AESI) included new/worsening graft versus host disease, graft failure or rejection, cytokine release syndrome, infusion related reactions, new/worsening pneumonitis, and progressive dyspnea. Treatment-related refers to the assessment of a relationship between study treatment and the event by the investigator. |
| Primary | Change in Viral Load From Baseline to Day 28 (Part B) | Baseline and Day 28 (Part B) | Change from Baseline in viral load as measured by quantitative PCR of nasal swab |
| Secondary | Identify the Recommended Phase 2 Dose (RP2D) (Part A) | Day 1 up to 12 months | The RP2D was to be determined after the maximum tolerated dose was reached in Part A. |
| Secondary | Change in Viral Load Cycle Threshold From Baseline to Day 28 (Part A) | Baseline and Day 28 | Viral load was measured by quantitative polymerase chain reaction (PCR) of nasal swab specimens. The cycle threshold value categorizes the concentration of viral genetic material in a participant's swab specimen, and the cycle threshold value represents the number of PCR cycles required to amplify the viral genetic material (as measured by fluorescence) to a detectable level that is distinguishable from baseline fluorescence, providing an estimate of viral load. Lower cycle threshold values indicate higher viral load and high values indicate lower viral load. A positive change from baseline indicates a decrease in the viral load. The baseline measurement was from a pre-dose nasal swab. |
| Secondary | Number of Participants With Treatment-emergent Adverse Events (TEAEs) (Part B) | Day 1 up to 12 months | |
| Secondary | Percentage Reduction in Viral Load From Baseline to Month 6 (Part B) | Day 1 and Month 6 |
