A Phase 1/2, Prospective,Randomized, Active-Controlled, Double-Blind, Age De-escalation Study to Evaluate the Safety, Tolerability, Immunogenicity of Serum Institute of India's PCV10 in Healthy Adults, Toddlers, and Infants
In Brief
A Phase 2 clinical trial evaluating SIILPCV10, Pneumovax 23, and 1 other intervention for Pneumococcal Disease. Completed, enrolled 346 participants across 1 site.
Detailed Summary
Phase 1/2, Prospective, Single Center, Randomized, ActiveControlled, Double-Blind, Age De-escalation Study to assess the safety and tolerability of SIILPCV10 administered as a single-dose regimen to healthy Gambian pneumococcal conjugate vaccine (PCV)-naïve young adults and PCV-primed toddlers through 4 weeks post vaccination. Each adult and toddler subject will undergo a total of 4 clinic visits. Each infant subject will undergo a total of 9 scheduled visits. Blood will be collected from all subjects during the screening visit for safety and potential immunological assessments, and 28 days after completion of the vaccination schedule for immunological assessments. For adults, the vaccine was given intramuscularly into the mid-deltoid muscle of nondominant arm using a 24-gauge needle. For toddlers and infants, the vaccine will be given IM into the anterolateral aspect of the left thigh. Blood will be collected from adults and toddlers for safety labs at the Day 7 post-vaccination visit.
