Trial Outcomes & Findings for Safety, Tolerability, and Pharmacokinetics of RSV Monoclonal Antibody RSM01 in Healthy Adults (NCT NCT05118386)

NCT ID: NCT05118386

Last Updated: 2024-05-20

Results Overview

A TEAE was any untoward medical occurrence in a clinical study participant, temporally associated with the use of a study intervention, whether or not considered related to the study intervention. A memory aid was utilized by participants to collect unsolicited TEAEs beginning at discharge from the clinic, through Day 151. Participants were instructed to record unsolicited TEAEs whenever they occurred, recording such TEAEs on the memory aid. The memory aids were collected and reviewed by site staff at each subsequent visit through the end of the study. Number of participants with unsolicited TEAEs through Day 151 has been presented.

Population: Safety Population

An SAE is any untoward medical occurrence that, at any dose results in death, is life-threatening, requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent disability/incapacity, is a congenital anomaly/birth defect or any other situation according to medical or scientific judgment. AESIs were defined as events of potential immunologic etiology, including immune-related AEs (irAEs). Number of participants with SAEs and AESIs through Day 151 has been presented.

Solicited systemic AEs were defined events that participants were specifically asked about and which were noted by participants in the diary card. Systemic solicited AEs included fever, headache, tiredness, joint pain, muscle pain, nausea, vomiting and diarrhea. Number of participants with solicited systemic AEs for 7 days after dose administration has been presented.

SECONDARY outcome

Timeframe: Day 151

Population: Pharmacokinetic (PK) population: included all participants who received the study intervention. Only those participants with data available at the specified data points were analyzed.

Blood samples were collected at indicated time points for pharmacokinetic (PK) analysis of RSM01. PK parameters were analyzed using standard non-compartmental analysis. AUC(0-infinity) in participants with AUC extrapolation exceeding 20% was deemed unreliable in the terminal phase and thus omitted from the summary statistics.

NA indicates standard deviation could not be calculated as a single participant was analyzed.

SECONDARY outcome

Timeframe: Day 151

Population: PK population. Only those participants with data available at the specified data points were analyzed. Data has been presented only for participants who received RSM01 intramuscularly.

Blood samples were collected at indicated time points for PK analysis of RSM01. PK parameters were analyzed using standard non-compartmental analysis. Vz post intramuscular administration in participants with AUC extrapolation exceeding 20% was deemed unreliable in the terminal phase and thus omitted from the summary statistics.

SECONDARY outcome

Timeframe: Baseline (Day 1) and post-Baseline through Day 151

Population: Immunogenicity Population: all participants who received the study intervention and have at least one valid ADA result

Whole blood samples in serum separator tubes and volumetric absorptive microsampling (VAMS) samples were collected for detection of ADAs against RSM01 in serum and capillary blood, respectively. The detection of ADA to RSM01 was performed using a validated immunoassay method with tiered testing of screening, confirmatory, and titration. Number of participants with positive ADAs at Baseline and post-Baseline through Day 151 following RSM01 administration has been presented.
