Nanocovax, researched and developed by Nanogen, consists of recombinant spike-protein subunits bound to silica nanoparticles. A Phase 2 study of Nanocovax was successfully conducted with 560 subjects and robust immune responses, including a strong IgG response as measured by the sCOVG test were observed in all vaccinated subjects.

Nanocovax, developed by startup Nanogen Pharmaceutical Biotechnology in collaboration with Vietnam Military Medical University, started the final trials on Thursday, the company said.

Nanocovax induced high levels of anti-S antibody (Ab). Neutralising antibody titres were evaluated by micro-neutralisation (against the original (Wuhan) strain and the Alpha variant) and surrogate virus neutralisation test. Importantly, Nanocovax conferred a remarkable protection against SARS-CoV-2 infection in hamster challenge model.6

ABSTRACT. Background Nanocovax is a recombinant severe acute respiratory syndrome coronavirus 2 subunit vaccine composed of full-length prefusion stabilized recombinant SARS-CoV-2 spike glycoproteins (S-2P) and aluminum hydroxide adjuvant. Methods We conducted a dose-escalation, open label trial (phase 1) and a randomized, double-blind, ...

In case of emergency approval, Vietnam would be able to produce 100 million doses per year. Nanocovax of Nanogen Pharmaceutical Biotechnology JSC is currently Vietnam's Covid-19 vaccine with the most potential. This vaccine is now in the third phase of trial, with the participation of 1,000 volunteers.

Nanocovax is a subunit vaccine, developed and manufactured at Nanogen Pharmaceutical Biotechnology JSC., containing full-length prefusion stabilized recombinant SARS-CoV-2 S glycoproteins and aluminium hydroxide adjuvant. In rodent and monkey models, Nanocovax induced high levels of anti-S antibody (Ab).

In early August, India's Vekaria Pharmaceutical Group inked a deal with Nanogen to supply Nanocovax to the world's second-most populous country. The deals are expected to help the Vietnamese-made COVID-19 vaccine soon join global supply chain, easing the global shortfall of COVID-19 vaccines.

This is a phase 3, adaptive, multicenter, randomized, double-blind, placebo control study to evaluate the safety, immunogenicity, and efficacy of the Nanocovax vaccine against COVID-19 in volunteer subjects 18 years of age and older. Age stratified as 18-45, 45-60, and > 60 years of age.

Conclusions Up to 42 days, Nanocovax vaccine was safe, well tolerated and induced robust immune responses. We propose using Nanocovax 25 mcg for Phase 3 to evaluate the vaccine efficacy.
