Dengue virus (DENV) is a member of the flavivirus family causing dengue fever, a mosquito-borne disease that can be life-threatening. Despite DENV’s widespread presence in over 80 countries and the significant health burden posed by the infection, there is still a critical need for therapeutics and vaccines, with current treatment options only providing supportive care.

CEPI is partnering with Astrazeneca plc to advance VHH-based multispecific antibodies targeting influenza, while Harbour Biomed Ltd. has entered into a global strategic collaboration with Astrazeneca to discover and develop next-generation multispecific antibodies for immunology, oncology and other diseases.

Taimed Biologics Inc.’s TMB-365/TMB-380 long-acting combination of broadly neutralizing antibodies regimen for HIV maintenance could reshape HIV treatment management, offering a viable alternative to daily combination antiretroviral therapy (cART), the Taipei-based company said after reporting on phase IIa results.

Sanofi SA is getting deeper into oncology and immunology therapy development through buying Dren Bio Inc.’s myeloid cell engager for deep B-cell depletion, DR-0201. The deal could reach as high as $1.9 billion for privately held Dren. Sanofi is paying a hefty $600 million up front, and milestone payments to come could add up to $1.3 billion.

Ampersand Biomedicines Inc. has secured $65 million in series B funding from investors including Ampersand’s founder, Flagship Pioneering, to support advancement of two lead programs and a new discovery partnership in obesity.

Multisystem inflammatory syndrome in children (MIS-C), a serious disorder that develops after SARS-CoV-2 infection, could arise from latent infection of another pathogen, the Epstein-Barr virus (EBV). Researchers at Charité – Universitätsmedizin Berlin and the German Rheumatology Research Center (DRFZ) have linked the inflammatory effect of this co-infection with transforming growth factor β (TGF-β), ruling out the possibility that MIS-C is caused by an autoimmune reaction, or persistence of the coronavirus in the body.

Roivant Sciences Ltd. CEO Matt Cline said the firm’s unit Immunovant Inc. with FcRn blocker batoclimab has established “frankly a new bar” in myasthenia gravis (MG) as the New York-based firm reported top-line results from its phase III study and first data from period 1 of the phase IIb study with the same drug in chronic inflammatory demyelinating polyneuropathy. The data look promising, and Immunovant intends to use the findings to help advance second-generation FcRn prospect IMVT-1402 in both indications. Potentially registrational trials are planned. The U.S. FDA has granted IND clearance.

Oxford Biotherapeutics Ltd. is partnering with Roche AG to expand the current field of tumor antigens that can be drugged with antibodies, as part of a potential $1 billion-plus agreement. The agreement will see Oxford Biotherapeutics apply its membrane protein discovery platform to search for novel cancer cell antigens, which will be validated through the research collaboration, with Roche then taking the lead in advancing any resulting antibody programs.

Japanese-founded Regcell Inc. has raised $45.8 million and is redomiciling to the U.S. to accelerate clinical development of its pioneering regulatory T-cell (Treg) platform for autoimmune diseases and transplantation.
