UB-612 is a COVID-19 vaccine candidate developed by United Biomedical, Inc. Asia, Vaxxinity (formerly known as COVAXX), and DASA.[1] It is a peptide vaccine.[2][3]

Technology

UB-612 is a peptide vaccine incorporating multiple epitopes, including the spike protein receptor binding domain as well as other virus structural proteins.[1][3] The spike protein peptide is fused to an Fc domain of single-chain IgG1, and the other six peptides are derived from highly conserved sequences from the spike, nucleocapsid, and membrane proteins of SARS-CoV-1 and SARS-CoV-2. It also contains a proprietary UBITh1 peptide derived from the measles virus fusion protein, CpG oligonucleotides, and aluminum phosphate adjuvant to improve the immune response. It is produced in CHO cells.[2]

Clinical trials

In September 2020, UB-612 started phase I clinical trials in Taiwan.[4]

In January 2021, UB-612 started phase II clinical trials in Taiwan.[5]

In February 2021, UB-612 started phase II/III clinical trials.[6]
