Immunovant's Batoclimab Succeeds in Phase 3 Trial, but Company Pivots to Next-Gen Candidate
Immunovant, a biotechnology company focused on developing treatments for autoimmune diseases, has announced positive results from a phase 3 trial of its FcRn inhibitor batoclimab in myasthenia gravis. However, in an unexpected turn of events, the company has decided not to pursue regulatory approval for the drug, instead opting to focus on its second-generation molecule, IMVT-1402.
Phase 3 Trial Results and Strategic Shift
The phase 3 trial of batoclimab demonstrated significant improvements in patients with myasthenia gravis. Low and high doses of the drug led to 4.7- and 5.6-point improvements, respectively, on the MG-ADL symptom and activity scale, compared to a 3.6-point improvement in the placebo group. These results successfully met the trial's primary endpoint.
Despite this success, Immunovant CEO Pete Salzmann, M.D., confirmed at the J.P. Morgan Healthcare Conference in January that the company's "base case" was to forgo commercialization of batoclimab. This decision appears to be driven by concerns over batoclimab's effect on albumin levels and, consequently, cholesterol.
Competitive Landscape and Next Steps
Immunovant's decision to prioritize IMVT-1402 places the company at a competitive disadvantage in the short term. Rivals such as argenx and Johnson & Johnson have already made significant strides in the FcRn inhibitor market. Argenx's Vyvgart received FDA approval in 2021, with a subcutaneous version launched in 2023.
Matt Gline, CEO of Immunovant's majority shareholder Roivant, expressed confidence in the potential of IMVT-1402, stating, "What we're clearly gonna be able to do better, based on this dataset, is get deeper faster and hold those responses for longer. That's the impact of the deeper IgG suppression that we deliver."
Investor Reaction and Analyst Perspectives
The news of Immunovant's strategic shift was met with mixed reactions. The company's stock fell 10% to below $17 in pre-market trading following the announcement. However, some analysts remain optimistic about the long-term potential of Immunovant's approach.
Piper Sandler analyst Yasmeen Rahimi, Ph.D., commented on the significance of the data, saying, "The most important thing that you proved, and that's incredible, is the debate on whether deeper matters. I think this data today, this morning, really put that to rest."
As Immunovant refocuses its efforts on IMVT-1402, the pharmaceutical industry will be watching closely to see if the company's bold strategy pays off in the competitive autoimmune disease market.

A phase 3 trial of Immunovant’s FcRn inhibitor batoclimab has hit its primary endpoint. But, having made a second-generation molecule its lead candidate last year, the biotech isn’t currently planning to file for batoclimab approval in myasthenia gravis or chronic inflammatory demyelinating polyneuropathy.
