Food and drug administration Clears Vaxart’s IND Software for S-Only Oral Pill COVID-19 Vaccine Candidate

Vaccine candidate expressing S-only protein generated higher serum antibodies than build expressing both S and N in NHP research

Period II scientific trial with S-only applicant to commence in 2H21

Advancement of this and other S-only constructs will progress in parallel with that of S+N construct, as previously declared

SOUTH SAN FRANCISCO, Calif., Aug. 2, 2021 /PRNewswire/ — Vaxart, Inc., (NASDAQ: VXRT), a clinical-phase biotechnology enterprise establishing oral vaccines administered by tablet, introduced now that the U.S. Food stuff and Drug Administration has cleared Vaxart’s Investigational New Drug application for an S-only oral pill SARS-CoV-2 vaccine candidate.

“This is terrific news since it allows us to transfer forward with our 1st S-only vaccine assemble,” mentioned Andrei Floroiu, Vaxart’s Chief Govt Officer. “As we said at the end of the first quarter, we will discover various S-only constructs in medical trials together with the S+N build that has currently concluded its Period I trial.

“Collectively, the S-only and S+N constructs are portion of our special oral tablet COVID-19 vaccine applicant portfolio, which we believe that could make a significant contribution to the battle towards COVID-19 globally.”

“Preliminary facts from our present Non-Human Primate study indicates that the S-only vaccine developed a lot larger serum antibodies than the a person expressing both S and N proteins,” mentioned Dr. Sean Tucker, Vaxart’s Chief Scientific Officer. “Our Period I final results from the S+N vaccine applicant confirmed impressive T-mobile responses and a mucosal antibody reaction, but not as strong serum antibody responses.

“This new medical trial will permit us to examine the S-only and S+N vaccine candidates and place us in a placement to determine which solution features the greatest way ahead for our COVID-19 vaccine progress method, especially in the encounter of rising variant strains.”

Vaxart introduced in February that it had done a Section 1 medical trial for its oral S+N COVID-19 vaccine. The success from that analyze uncovered that the investigational oral vaccine triggered many immune responses versus SARS-CoV-2 antigens, while reaching major and secondary endpoints of security and immunogenicity, respectively.
