Another PD-1 antibody is about to hit the U.S. market, following the FDA’s accelerated approval of dostarlimab (TSR-042) from partners Anaptysbio Inc. and Glaxosmithkline plc. But dostarlimab, branded Jemperli, will be only one of two PD-1 drugs indicated for endometrial cancer, going up against Merck & Co. Inc.’s Keytruda (pembrolizumab).
In the debate over the interpretation of the U.S. government’s patent march-in rights under the Bayh-Dole Act, those arguing for march-in as a price control cite the billions of tax dollars being invested in scientific research at universities that may lead to marketable inventions.
Citing the limited data for CAR T therapies in treating multiple myeloma, the Institute for Clinical and Economic Review said their cost-effectiveness for some patients will depend on whether a second dose is needed.
Less than two months after scrubbing a phase III non-small-cell lung cancer trial of the bifunctional fusion protein immunotherapy bintrafusp alfa, Merck KGaA said a phase II test of the candidate in another indication, biliary tract cancer, has missed a predefined threshold that would have enabled a regulatory filing for it. Both studies are part of a rich alliance between Merck and licensee Glaxosmithkline plc.
LONDON – The largest study of its kind to date has identified new biomarkers of inflammation that are both indicators of severe COVID-19 infection and distinguish it from severe influenza.
Positive COVID-19 efficacy numbers from Vir Biotechnology Inc. and Glaxosmithkline plc (GSK) has prompted them to immediately seek an emergency use authorization (EUA) with the FDA and similar authorizations in other countries for their monoclonal antibody, VIR-7831. Meanwhile, the phase III Remdacta study of Actemra/RoActemra (tocilizumab) plus Veklury (remdesivir) vs. placebo plus Veklury, from Roche Holding AG and Gilead Sciences Inc., missed its primary endpoint in treating hospitalized patients with severe COVID-19 pneumonia receiving standard of care.
DUBLIN – Glaxosmithkline plc and Anaptysbio Inc. were able to get over some of the disappointment arising from a delayed FDA decision on their PD-1 inhibitor, dostarlimab, earlier this month, as the EMA came through Feb. 26 with a positive recommendation for the drug in endometrial cancers that are deficient in DNA mismatch repair or that are categorized as having high microsatellite instability.
LONDON – Two new U.K. studies point to long-term persistence of COVID-19 antibodies after both natural infection and vaccination, conferring protection against subsequent infection for at least three months.
Marking the first time monoclonal antibodies developed by separate companies will be tested in combination against COVID-19, Vir Biotechnology Inc.’s VIR-7831 will be added to Eli Lilly and Co.’s bamlanivimab in the ongoing phase II BLAZE-4 study in low-risk patients with mild to moderate disease. The collaboration comes as early research indicates some antibodies in development appear to lose activity when pitted against emerging SARS-CoV-2 variants. VIR-7831 (also known as GSK-4182136), partnered with Glaxosmithkline plc, is designed to bind to a different epitope of the SARS-CoV-2 spike protein than bamlanivimab. A dual-action antibody, VIR-7831 is designed to both block viral entry into healthy cells and clear infected cells.
