Clover has also initiated development of additional vaccine programs including multivalent SARS-CoV-2 (covering multiple variants), rabies and influenza. SCB-313, a novel TRAIL-Trimer fusion protein targeting intracavitary malignancies (including malignant ascites), is in multiple ongoing Phase I clinical trials in Australiaand China, with encouraging efficacy signals and a favorable safety profile demonstrated to-date. Clover also expects to advance multiple new pipeline products to the clinic in 2021 and further expand its in-house R&D and cGMP commercial biomanufacturing capabilities.

About Trimer-Tag© Technology

Trimer-Tag© is an innovative drug development platform which allows the production of novel, covalently-trimerized fusion proteins. Many major disease targets are trimerization-dependent such as the tumor necrosis factor (TNF) superfamily (involved in extrinsic apoptosis, immune co-stimulation and inflammation) as well as enveloped RNA virus antigens responsible for entry into host cells. Clover is using its Trimer-Tag© technology with global IP position to develop recombinant trimerized fusion proteins that can effectively target these previously undruggable pathways.
