Big Strides for Autoimmune Diseases: Batoclimab Impresses in Trials

When you see a new treatment crush its goals in tough-to-treat diseases, it grabs attention. That’s exactly what happened with Immunovant and its antibody therapy batoclimab, which posted encouraging Phase II results for MG (myasthenia gravis) and CIDP (chronic inflammatory demyelinating polyneuropathy). These aren’t your everyday conditions—living with muscle weakness or nerve problems is life-altering, and effective options are limited. So, progress here matters.

If you’re following the data, here's what stands out: In the myasthenia gravis study, people taking higher doses of batoclimab saw their MG-ADL (Myasthenia Gravis Activities of Daily Living) scores jump by 5.6 points by week 12. Lower doses weren’t far behind, notching a 4.7-point improvement. The main target was people who tested positive for acetylcholine receptor antibodies, and they clearly benefitted. The drug doesn’t just help on paper — it means real changes for patients struggling with daily activities.

It's not just MG. In CIDP, data pooled from 73 individuals revealed a 1.8-point bump in their adjusted INCAT scores, a tool that measures the level of disability in these nerve disorders. More telling was the responder rate: a whopping 84% of people who had their IgG antibodies slashed by at least 70% actually responded to the drug. Beyond that, folks got stronger (as seen in grip strength and muscle tests) and reported real improvements in daily life. Side effects stayed steady and predictable, which is always a plus with new immunotherapies.

IMVT-1402 Steps Up: What’s Next in the Pipeline?

Immunovant isn’t hitting pause. Building off this success, the company is gearing up to launch new registrational trials for their next candidate, IMVT-1402, in both MG and CIDP. What makes this one different? It’s an easy-to-use shot under the skin and is designed for even more dramatic drops in IgG. If the company’s hunch is right, IMVT-1402 could edge out other anti-FcRn drugs, making life easier for patients who now shuffle between doctors and treatments, trying to find something that sticks.

Beyond those core diseases, Immunovant is widening its aim. There’s buzz around the Phase II trial data for batoclimab in Graves’ disease — the tough cases where folks aren’t getting better with routine treatment. Over half of those hard-to-treat patients responded to batoclimab, and since it’s currently the only subcutaneous option in its drug class, it could end up changing the landscape for people with this thyroid disorder.

2025 looks busy at Immunovant. The company has kicked off advanced studies for IMVT-1402 not just in MG and CIDP, but also rheumatoid arthritis (specifically the stubborn ACPA-positive and diffuse-to-symmetrical forms) and cutaneous lupus. Early proof-of-concept signs are good, and management seems pumped about extending their reach to even more rare, stubborn autoimmune conditions.

The company’s financials are stable for now, and trial enrollments are moving steadily. If things keep going this way, Immunovant is on track to deliver treatments that could reset what people expect from autoimmune therapy — not just easing symptoms but setting a new bar for effectiveness and ease of use. Trials will tell whether these early wins lead to real-world breakthroughs, but for patients and families watching from the sidelines, there’s finally some fresh hope.
