Trial Outcomes & Findings for COVID-19 Vaccine Boosters in Patients With CKD (NCT NCT05022329)

NCT ID: NCT05022329

Last Updated: 2025-02-19

Results Overview

To measure Anti-Spike, Anti-NP antibodies, and SARS-CoV-2 specific neutralization at 1 month (30 days) following third dose of vaccine (BNT162b2 versus mRNA-1273) binding antibody levels for anti-receptor-binding domain and antispike IgG were reported as relative ratios to a synthetic standard included as a calibration curve on each assay plate.

PRIMARY outcome

Timeframe: One month

Population: 7 participants withdrew from each arm and were not included in analysis. Only participants who provided samples for this timepoint were included in the analysis.

To measure Anti-Spike, Anti-NP antibodies, and SARS-CoV-2 specific neutralization at 1 month (30 days) following third dose of vaccine (BNT162b2 versus mRNA-1273) binding antibody levels for anti-receptor-binding domain and antispike IgG were reported as relative ratios to a synthetic standard included as a calibration curve on each assay plate.

Outcome measures

Outcome data not reported

SECONDARY outcome

Timeframe: 1 month

Population: Analysis on this subset was not feasible following study completion. The collaborating laboratory was unable to logistically perform this testing due to the resources required for Flow Cytometry, and therefore this secondary outcome was not analyzed.

In a subset of participants, assess cellular immunity through flow cytometry on PBMC and single-cell RNA sequencing prior to, one month, and 6 months following vaccine booster.

Population: Population consists of only individuals who returned the completed survey.

Evaluate adverse events related to third dose of vaccine through a questionnaire within 48 hours to 14 days following third vaccine dose.
