New preclinical data from Immunome Inc. gets the company closer to the clinic for studying its three-antibody cocktail’s effect on SARS-CoV-2. “We will file an IND this quarter and get into the clinic,” Immunome’s CEO, Purnanand Sarma, told BioWorld. “Since the number of cases is rising, unfortunately, we think a clinical study could be conducted reasonably quickly.”
Aditxt Technologies Inc. enhanced its immune response test for COVID-19 by adding a high-sensitivity neutralizing antibody quantification. With the expansion, the multidimensional test, Aditxtscore, provides a comprehensive measure of the strength of an individual's immune response to the novel coronavirus.
There’s been a mixed bag of data from Astrazeneca plc’s efforts against COVID-19, after data suggested Pfizer Inc.’s rival vaccine is more effective against the Delta variant and the failure of a trial involving its long-acting antibody therapy.
In reporting positive data from a phase III study of sugemalimab in treating stage III non-small-cell lung cancer (NSCLC), Cstone Pharmaceuticals Co. Ltd. and Eqrx Inc. have the first anti-PD-L1 monoclonal antibody demonstrating progression-free survival in patients with concurrent or sequential chemoradiotherapy.
There are now two FDA-backed monoclonal antibody COVID-19 treatments after the agency granted Glaxosmithkline plc (GSK) emergency use authorization (EUA) for single-dose sotrovimab to treat mild to moderate COVID-19 in adults and children as young as 12. Vir Biotechnology Inc. collaborated on the program.
A new study by Laboratory Corp. of America Holdings (Labcorp) has found that nearly 9 in 10 COVID-19 patients continue to have antibodies to SARS-CoV-2 proteins 10 months after infection. Published in The Lancet-affiliated Eclinicalmedicine, the study provides real-world evidence of the persistence of SARS-CoV-2 antibodies in infected individuals, though the authors said more research is needed to determine if, and to what degree, protection against reinfection persists.
DUBLIN – Numab Therapeutics AG has moved closer to the front rank of European antibody developers by raising CHF100 million (US$111 million) in a series C financing round to accelerate the development of NM21-1480, a trispecific antibody that acts both as a PD-L1 inhibitor and 4-1BB (CD137) agonist. It also contains a human serum albumin recognition group, to extend its circulatory half-life.
LONDON – Antibody prospecting specialist Alchemab Therapeutics Ltd. has raised £60 million (US$82.7 million) in a series A round, to take programs in neurodegenerative diseases and cancer into the clinic.
LONDON – Getting a handle on the specificity and sensitivity of rapid COVID-19 antibody tests, how they compare to each other and how they should be applied in population screening to understand who has had the virus and how it has spread, has been a source of difficulty and dispute between manufacturers, clinicians and public health experts.
Shares of Humanigen Inc. (NASDAQ:HGEN) leapt 54.5% to $21.61 March 29 on news that its monoclonal antibody, lenzilumab, improved the relative likelihood of survival without mechanical ventilation in hospitalized patients with COVID-19, setting the company up to submit an application for emergency use authorization (EUA) in the U.S. "as soon as possible," it said. Separately, a combination of two monoclonal antibodies, the Eli Lilly and Co.-Abcellera Biologics Inc.-developed therapy bamlanivimab and the Vir Biotechnology Inc.-Glaxosmithkline plc candidate VIR-7831, demonstrated a 70% relative reduction in persistently high SARS-CoV-2 viral load at day seven compared to placebo for low-risk adult patients with mild to moderate COVID-19, the companies reported.
