Covaxx has hired CRO PPD for a Phase II/III trial of its Covid-19 vaccine candidate UB-612 in Brazil beginning this quarter, CEO Mei Mei Hu said. The Hauppauge, NY-based Covaxx enlisted PPD due to its quality, ability to quickly recruit trials and competency in interfacing with local regulators, Hu said.

Covaxx is also collaborating with Dasa, the largest diagnostic medical company in Brazil, for the Phase II/III and for vaccine distribution, Hu added. The Phase II/III (NCT04683224) will enrol more than 10,000 patients and measure disease severity and infection among its primary endpoints, while also looking at viral shedding, Hu said. In addition to the Brazil trial, Covaxx is initiating a 3,500-patient Phase II safety and immunogenicity trial in Taiwan this quarter, funded by a grant from the Taiwanese government, with an undisclosed, locally based CRO, Hu said. Covaxx is also working with India-based Aurobindo to develop and commercialise the vaccine in India, she added.

Results from a Phase I trial of UB-612, which the company plans to release shortly, were positive, finding a 100% seroconversion rate in patients and neutralising titers at or above convalescent plasma levels, Hu said. UB-612 is a multitope peptide-based vaccine activating both B and T-cells in the immune system, according to the company website.

Covaxx plans to merge with its sister company United Neuroscience later this quarter to form a new company, called Vaxinity, which will include both companies’ entire vaccine platforms, Hu said. The new company will look to raise an undisclosed amount of capital, she added. All Covid-19 trials are funded through company partnerships and government grants, she explained.

PPD declined a request to comment.
