An experimental HIV vaccine based on mRNA—the same platform technology used in two highly effective COVID-19 vaccines—shows promise in mice and non-human primates, according to scientists at the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health. Their results, published in Nature Medicine, show that the novel vaccine was safe and prompted desired antibody and cellular immune responses against an HIV-like virus.

Roche announced that the European Commission has extended the marketing authorisation for Actemra®/RoActemra® (tocilizumab) to include the treatment of COVID-19 in adults who are receiving systemic corticosteroids and require supplemental oxygen or mechanical ventilation. This decision comes just hours after the recommendation by the European Medicines Agency's (EMA) Committee for Medicinal Products for Human Use (CHMP), reflecting the urgent need for Actemra/RoActemra as a potential treatment option during the COVID-19 public health emergency.

GlaxoSmithKline plc and Vir Biotechnology, Inc announced an update to preclinical data on bioRxiv1, a preprint server, demonstrating that sotrovimab, an investigational monoclonal antibody, retains in vitro activity against the full known Omicron spike protein, the new SARS-CoV-2 variant (B.1.1.529). The preclinical data was generated through pseudo-virus testing of the combined known mutations of the Omicron variant, which included the maximum number of changes (37 mutations) identified to date in the spike protein.

A common strategy to make vaccines more powerful is to deliver them along with an adjuvant — a compound that stimulates the immune system to produce a stronger response.

Researchers from MIT, the La Jolla Institute for Immunology, and other institutions have now designed a new nanoparticle adjuvant that may be more potent than others now in use. Studies in mice showed that it significantly improved antibody production following vaccination against HIV, diphtheria, and influenza.

LintonPharm Co., Ltd., a China-based clinical stage biopharmaceutical company focused on the development of T cell engaging bispecific antibodies for cancer immunotherapy, today announced that the first patient has been dosed in the Company’s Phase 1/2 clinical trial program for catumaxomab (clinicaltrials.gov: NCT04799847), a monoclonal bispecific antibody being studied for the treatment of Non-Muscle-Invasive Bladder Cancer (NMIBC) unresponsive to Bacillus Calmette-Guerin (BCG).

Premas Biotech announced that its joint venture Oravax will initiate testing of their oral virus-like particle (VLP) vaccine candidate against Omicron variant of SARS-CoV 2 virus through preclinical, in vitro and challenge studies to assess its efficacy for the new mutant strain. Premas Biotech, Oramed Pharmaceuticals, MyMD Pharmaceuticals, and certain other shareholders formed Oravax Medical to bring an oral COVID-19 vaccine to the market.

GlaxoSmithKline plc and Vir Biotechnology, Inc announced an update to bioRxiv, a preprint server, with preclinical data demonstrating that sotrovimab, an investigational monoclonal antibody, retains activity against key mutations1 of the new Omicron SARS-CoV-2 variant (B.1.1.529), including those found in the binding site of sotrovimab. These data were generated through pseudo-virus testing of specific individual mutations found in Omicron.

The first long-acting option to protect women from HIV, proven to reduce women’s HIV risk, has been recommended for use by the World Health Organization (WHO).

Moles and melanomas are both skin tumors that come from the same cell called melanocytes. The difference is that moles are usually harmless, while melanomas are cancerous and often deadly without treatment. In a study published today in eLife Magazine, Robert Judson-Torres, PhD, Huntsman Cancer Institute (HCI) researcher and University of Utah (U of U) assistant professor of dermatology and oncological sciences, explains how common moles and melanomas form and why moles can change into melanoma.
