Premas Biotech and Oramed Announce Oral COVID-19 Vaccine Candidate That Produces Antibodies After a Single Dose

• Far reaching implications for ease of widescale distribution and administration anytime, anywhere
• Better candidate for protection against COVID-19 variants due to triple antigen targeting
• Oravax Medical Inc. established to accelerate vaccine’s path to market
• Clinical trials expected to commence Q2 2021

(BUSINESS WIRE)-- Premas Biotech, a developer of novel biotherapeutic and vaccine candidates, announced today the development of an oral COVID-19 vaccine that has shown efficacy after a single dose, in conjunction with Oramed Pharmaceuticals Inc. (Nasdaq/TASE: ORMP).

Accelerating the vaccine’s path to market, Premas, Oramed and other shareholders, have formed Oravax Medical Inc. which has received exclusive licenses from Oramed and Premas to develop oral COVID-19 vaccines.

After a single dose of the Oravax COVID-19 capsule, efficacy was evident through antibody production in a pilot animal study. Oravax’s vaccine promoted both systemic immunity through Immunoglobulin G (IgG), the most common antibody in blood and bodily fluids that protects against viral infections, and Immunoglobulin A (IgA) which protects the respiratory and gastrointestinal tracts against infection.

Premas’ protein-based VLP (Virus Like Particle) vaccine candidate creates triple protection against the SARS CoV-2 virus Spike, Membrane, and Envelope targets. The vaccine candidate is also safe, efficacious and well tolerated at normal to high doses, and generated high titres of neutralizing antibodies. The VLP is manufactured using Premas’ proprietary D-Crypt™ platform, which is highly scalable and can be manufactured on large scales.

Premas Biotech Co-Founder and Managing Director Dr. Prabuddha Kundu commented, “An oral COVID-19 vaccine that harnesses and combines the true potential of the two platforms, Premas’ D-Crypt™ technology platform with Oramed’s world-leading oral protein delivery platform POD® is an excellent example of a true collaboration and can rapidly advance into late-stage clinical trials. Oramed’s experience and success in conducting Phase 2 and 3 oral protein trials positions our program very favorably in the race to find an effective oral COVID-19 vaccine that can be administered by anyone anywhere. We are looking forward to sharing clinical data soon.”

“We are very excited about our oral vaccine candidate’s potential to help end the pandemic,” said Nadav Kidron, CEO of Oramed. “An oral COVID-19 vaccine would eliminate several barriers to rapid, widescale distribution, enabling people to take the vaccine themselves at home. While ease of administration is critical today to accelerate inoculation rates, an oral vaccine could become even more valuable in the likely case that a COVID-19 vaccine may be required annually or biannually like the standard flu shot.”
