The hepatitis C virus (HCV) is so common that it infects approximately 0.7% of the world population to ultimately cause ~300,000 deaths each year. Small molecule-based antivirals can cure most HCV infections, but these are often only used after irreversible liver damage has already occurred, prohibitively expensive, and inaccessible for high-risk populations.
The controlled cell death process of apoptosis functions as the first step to any full recovery from injury or disease. In the second step of any recovery process, dead cells are cleared by efferocytosis, a process performed by phagocytotic cells like macrophages. Approximately 200-300 billion apoptotic cells are cleared daily by efferocytosis starting with the recognition of newly extracellular facing phosphatidylserine (PtdSer) by PtdSer-binding proteins present on phagocytotic cells.
Despite pipeline setbacks in 2022, TG Therapeutics Inc. ended the year on a positive note, with U.S. FDA approval of its glycoengineered CD20 monoclonal antibody, ublituximab, in relapsing multiple sclerosis (MS). Branded Briumvi, the drug is set to go up against approved anti-CD20 antibodies Kesimpta (ofatumumab, Novartis AG) and Ocrevus (ocrelizumab, Roche Holding AG).
Eleven vaccines have now been approved by the World Health Organization for preventing COVID-19, but all exhibit drastically reduced activities after 6 months. Unlike vaccines that express only the spike protein as the immunogen, live attenuated vaccines have the potential to confer a broader and more durable protection.
Ethris GmbH has entered into a collaboration with Diosynvax Ltd. to jointly develop a protective mRNA vaccine candidate against a broad range of betacoronaviruses utilizing the company's highly differentiated mRNA modification and design technologies as well as its lipidoid nanoparticle (LNP) and stabilization platforms.
Although ovarian cancers appear to be immunologically active, they do not respond well to immunotherapy in the clinic. In a study published on Dec. 14, 2022, in Nature, a multidisciplinary team at Memorial Sloan Kettering Cancer Center (MSK) led by Sohrab Shah and Dmitriy Zamarin has uncovered several mechanisms of immune evasion that can help explain why ovarian cancers have been resistant to immunotherapy to date.
With $20 million raised in a series B round led by Brandon Capital and Tenmile, Aravax Pty Ltd. is poised to begin phase II trials of its immunotherapy, PVX-108, for peanut allergy. “Our product is unlike other approaches that are in later stages of development, and those products generally use natural extracts from peanuts to treat peanut allergy,” Aravax CEO Pascal Hickey told BioWorld.
