Codagenix Presents Positive Phase 1 Data for COVI-VAC Intranasal COVID-19 Vaccine at IDWeek 2021


FARMINGDALE, N.Y., Sept. 29, 2021 /PRNewswire/ -- Codagenix, Inc.,  a clinical-stage biotechnology company pioneering a novel platform for vaccines and oncolytic virus therapies, today presented data from ongoing studies of their novel intranasal COVID-19 vaccine, COVI-VAC, at the IDWeek 2021 annual conference held virtually September 29-October 3.

The poster presentation entitled "Phase 1 Placebo-Controlled Trial of COVI-VAC™ an Intranasal, Live Attenuated COVID-19 Vaccine," includes data from the company's ongoing, dose escalation clinical study of COVI-VAC in healthy adults. Data indicates that COVI-VAC is well tolerated, with no significant adverse events reported across the 48 patients enrolled. Administration of the novel intranasal vaccine resulted in minimal viral shedding, recorded at levels lower than those likely to result in subsequent transmission of COVID-19. Furthermore, COVI-VAC was shown to stimulate both serum and mucosal antibody immune responses. Codagenix has partnered with the Serum Institute of India Pvt. Ltd. to co-develop and manufacture COVI-VAC with the aim of achieving large-scale distribution of the vaccine to meet global demand.

"The topline safety and immunogenicity data generated in our Phase 1 trial demonstrate potential for a live-attenuated vaccine that is safe, immunogenic and capable of blocking nasal replication of the virus. We are very encouraged by the data as we head into later stage clinical trials," said J. Robert Coleman, Ph.D., M.B.A., Co-Founder and Chief Executive Officer of Codagenix.

The company separately presented preclinical data indicating that COVI-VAC is efficacious and capable of generating antibodies against the heterologous Beta variant of SARS-CoV-2 (B.1.351) in animal models. This builds upon data recently published in the Proceedings of the National Academy of Sciences (PNAS, July 2021) that demonstrates COVI-VAC's safety and immunogenicity in Syrian golden hamsters.

Due to the virtual format of the IDWeek meeting, these poster presentations can be accessed online through December 31, 2021 for registered attendees. Presentation information is as follows:
