Although huge strides have been made with antiretroviral therapy (ART) and prevention since HIV was first reported 42 years ago, there is still not an effective preventive vaccine or a scalable cure for those living with HIV. But broadly neutralizing antibodies (bNAbs) look to be a further step down the pathway to a cure, speakers said during the International AIDS Society meeting held July 23 to 26 in Brisbane, Australia.
Singapore’s Agency for Science, Technology and Research (A*STAR) has inked a deal with Boehringer Ingelheim GmbH to develop and commercialize targeted cancer therapies.
Adagene Inc. has announced a research collaboration with Sanofi SA, to find “masked” monoclonal and bispecific antibodies that are safer than marketed drugs in oncology, in a deal worth up to $2.5 billion plus royalties. San Diego and Suzhou, China-based Adagene will generate masked versions of Sanofi antibodies, taking responsibility for early stage research activities using its Safebody technology.
Researchers at Inserm have developed a method to direct pre-existing antibodies toward new targets. Their bimodular fusion proteins could be a broadly useful method for expanding access to antibody therapy. In a study that appeared in the Feb. 11, 2022, issue of Science Advances, the teams showed that antibodies to Epstein-Barr virus (EBV), which are present in 95% of the global population, could be redirected to a target cell of their choosing by fusing an EBV antigen to a cellular targeting ligand.
Mabwell Bioscience Co. Ltd. raised ¥3.48 billion ($547.9 million) in a Shanghai STAR Market IPO on Jan. 18 to support company R&D efforts and plans to build an antibody production plant. Though oversubscribed, the offering got a cool market reception, with shares plunging nearly 30% from a ¥32 open (US$27.96), then closing at ¥24.50 on the first day of trading before recovering slightly to ¥27.40 on Jan. 20.
Targeting the toxic alpha-synuclein protein found in the brains of people with Parkinson’s is one of the most promising approaches to treat the disease in the clinic – but getting any drug into the brain is a challenge. Sanofi SA has joined with ABL Bio Inc. to solve this problem, in-licensing ABL-301, a preclinical bispecific antibody that locks on to misfolded alpha-synuclein but also includes a molecular “shuttle” that allows it to penetrate the blood-brain barrier.
Brii Biosciences Ltd. shared interim data from a phase III trial of its neutralizing monoclonal antibody (mAb) combination therapy for SARS-CoV-2, BRII-196 and BRII-198, that showed a 78% reduction in the risk of hospitalization or death in patients receiving single dose of the cocktail.
Celltrion Inc. has bagged its first green light outside Asia for its COVID-19 monoclonal antibody Regkirona (regdanvimab) with an emergency use authorization in Brazil. Brazil’s Anvisa gave the EUA for the drug to treat high-risk adult patients, including those aged 65 or older, with mild and moderate COVID-19 symptoms on Aug. 11. The regulator reached its decision on the drug, also known as CT-P59, via a unanimous vote.
Having created a profitable preclinical services business, Biocytogen Pharmaceuticals Co. Ltd. is now working to develop its own pipeline of antibody therapeutics, recently inking a partnership with China Resources Biopharmaceutical Co. Ltd. to develop drugs for oncology and immunology indications and raising “tens of millions of dollars” in a new financing round to support the development of its antibody drugs.
PERTH, Australia – Imagion Biosystems Ltd. has entered a collaborative research program with Patrys Ltd. to combine their technologies to target brain tumor imaging and diagnosis.
