The U.S. FDA has put five phase III studies of Sanofi SA’s potential multiple sclerosis and myasthenia gravis blockbuster tolebrutinib on partial clinical hold after several cases of liver injury were identified after exposure to the drug. Sanofi said new recruitment in the U.S. is paused and participants who have been part of the trial for fewer than 60 days should stop taking tolebrutinib, although those taking the drug for longer can continue.
The first gene therapy to treat severe hemophilia A was among the drugs recommended for European approval by regulators from the EMA’s CHMP at its monthly meeting. Manufactured by Biomarin Pharmaceutical Inc., Roctavian (valoctocogene roxaparvovec) was recommended for conditional marketing authorization in the EU for severe hemophilia A in adults who do not have factor VIII inhibitors and no antibodies to adeno-associated virus serotype 5.
Brightinsight Inc. and UCB SA struck a deal to jointly develop a digital disease management solution for patients with rare diseases. The companies will start with a mobile app for myasthenia gravis (MG) built on Brightinsight’s platform. UCB joins CSL Behring, Novo Nordisk A/S, Sanofi SA and Roche AG in partnering with Brightinsight on digital disease management.
LONDON – Neuromuscular disease specialist NMD Pharma A/S has raised €35 million (US$39.7 million) in a new financing, as it awaits initial data from its first clinical trial, in the treatment of myasthenia gravis. The new money enables NMD to complete that phase IIa study and to launch another trial of the same compound, NMD-670, in spinal muscular atrophy. The Aarhus, Denmark-based company is preparing the IND and aims to treat the first patient before the end of 2022.
Argenx NV’s Vyvgart (efgartigimod), approved late Friday by the FDA for treating generalized myasthenia gravis, became the first FcRn antagonist to cross the finish line. But the best news may be the drug’s broad label, which company executives highlighted during an investor call.
Harbour Biomed Therapeutics Ltd. said its anti-FcRn monoclonal antibody, batoclimab, generated top-line phase II data in generalized myasthenia gravis, and the company expects to move into a phase III study by the end of this year, with final data reported in April 2022.
Strong top-line results from Immunovant Inc.’s phase IIa clinical trial of IMVT-1401 in treating moderate to severe generalized myasthenia gravis increased the competition with Momenta Pharmaceuticals Inc. and Argenx SE in the crowded anti-FcRn space.
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.
New York-based Immunovant Inc.’s phase IIa results with neonatal Fc receptor (FcRn)-targeting IMVT-1401 in thyroid eye disease (TED), also known as Graves’ ophthalmopathy, prompted renewed speculation about the space, hot since the approval on Jan. 21 of Tepezza (teprotumumab-trbw) from Horizon Therapeutics plc, of Dublin.
