Clinical Trial Summary

This study will assess the safety, reactogenicity, and immunogenicity of Gam-COVID-Vac (Sputnik V) vaccine intended to provide acquired immunity against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causing coronavirus disease 2019 (COVID-19). The vaccine contains two recombinant adenoviral vectors harbouring SARS-CoV-2 Spike gene. The vaccine will be administered intramuscularly on a 2-dose prime-boost schedule. Participants will be healthy adults aged greater than or equal to 18 years, voluntarily undergoing vaccination according to the guidelines of the Ministry of Healthcare of Kazakhstan.

Description:

Sputnik V (Gam-COVID-Vac) is an adenoviral vector vaccine developed by The Gamaleya Research Institute of Epidemiology and Microbiology (Moscow, Russia), registered and approved by the Ministry of Healthcare of Kazakhstan. The vaccine incorporates two recombinant adenoviral (rAd) vectors, rAd5 and rAd26, harbouring SARS-CoV-2 Spike (S) gene. Earlier Phase I/II clinical trials established that Sputnik V is safe and efficacious when given intramuscularly in two sequential doses, as a rAd26-S prime at day 0 followed by rAd5-S boost at day 21, at 1x10^11 particles per dose. The aim of the current study is to provide data on the safety, reactogenicity, and immunogenicity of Sputnik V in adults vaccinated in Kazakhstan using the established vaccination regimen. In addition, the effects of prior COVID-19 exposure on the vaccine safety, reactogenicity, and immunogenicity will be assessed.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Number of Participants with Solicited Adverse Events (AEs) for 21 Days after First Vaccination	Solicited AEs are pre-defined local (at the injection site) and systemic adverse events, for which participants are questioned. Solicited local AEs include injection site pain, redness, swelling, itching. Solicited systemic AEs include fatigue, headache, myalgia, chills, fever, joint pain, nausea, vomiting, diarrhea, abdominal pain, rash external to injection site.	day 21
Primary	Number of Participants with Solicited Adverse Events (AEs) for 42 Days after First Vaccination	Solicited AEs are pre-defined local (at the injection site) and systemic adverse events for which participants are questioned. Solicited local AEs include injection site pain, redness, swelling, itching. Solicited systemic AEs include fatigue, headache, myalgia, chills, fever, joint pain, nausea, vomiting, diarrhea, abdominal pain, rash external to injection site.	day 42
Primary	Change in the Titres of Systemic SARS-CoV-2 Binding Antibodies	The titres of SARS-CoV-2 binding antibodies measured in serum/plasma.	Up to 6 months
Secondary	Change in the Titres of Mucosal SARS-CoV-2 Binding Antibodies	The titres of SARS-CoV-2 binding antibodies measured in mucosal (nasal) swabs.	Up to 6 months
Secondary	Change in the Titres of Systemic SARS-CoV-2 Neutralizing Antibodies	The titres of SARS-CoV-2 neutralizing antibodies measured in serum/plasma.	Up to 6 months
Secondary	Change in the titres of Mucosal SARS-CoV-2 Neutralizing Antibodies	The titres of SARS-CoV-2 neutralizing antibodies measured in mucosal (nasal) swabs.	Up to 6 months
Secondary	Change in the concentration of systemic cytokines	The levels of cytokines measured in blood plasma.	Up to 6 months
Secondary	Difference in the study outcomes between participants with and without prior COVID-19 exposure.	The reactogenicity and immunogenicity readouts will be compared between participants with and without prior COVID-19 exposure, as defined by the presence of SARS-CoV-2-reactive antibodies prior to vaccination.	Up to 6 months
