Immunovant Inc. is seeking a $450 million windfall on the back of the “best-in-class potential” of its early stage monoclonal antibody for IgG-mediated autoimmune diseases, IMVT-1402, which a phase I readout demonstrated could supersede the firm’s lead, batoclimab.
Less than a month after informing the market of a slowdown caused by pandemic-related site closures in phase II studies with neonatal Fc receptor (FcRn)-targeting IMVT-1401, Immunovant Inc. said it’s voluntarily pausing dosing with the compound in thyroid eye disease (TED) in the study called Ascend Go-2 because of a worrisome physiological signal. The New York-based firm plans to investigate and, after seeking the FDA’s go-ahead on tweaks to the program, forge onward with development.
Argenx SE’s later-stage effort with antibody fragment efgartigimod in generalized myasthenia gravis (gMG) was designed with guidance from the phase II trial that showed 75% of patients had a durable response of at least six weeks.
