Batoclimab

The FDA has approved Johnson & Johnson's anti-FcRn antibody, nipocalimab, for the treatment of generalized myasthenia gravis. The drug will be sold under the brand name IMAAVY. This approval positions J&J to challenge leading competitors in the myasthenia gravis market, such as AstraZeneca, which markets the monoclonal antibodies SOLIRIS and ULTOMIRIS. J&J will also be competing with Argenx's VYVGART and UCB's RYSTIGGO and ZILBRYSQ. LAS VEGAS, May 22, 2025 /PRNewswire/ -- Myasthenia gravis is an autoimmune disorder in which antibodies disrupt the communication between nerves and muscles, resulting in skeletal muscle weakness. This weakness primarily affects voluntary muscles that control eye movement, facial expression, swallowing, and limb function. The condition is predominantly driven by autoantibodies targeting either the acetylcholine receptor (AChR-Ab) or a receptor-associated protein known as muscle-specific tyrosine kinase (MuSK-Ab). According to DelveInsight's analysis, there were approximately 300,000 diagnosed prevalent cases of myasthenia gravis across the 7MM in 2024. This number is expected to grow steadily over the forecast period (2025–2034), with a projected CAGR. The current myasthenia gravis therapeutics market mainly consists of symptomatic treatments such as acetylcholinesterase inhibitors like Mestinon. However, achieving full clinical remission with symptomatic therapy alone is challenging. As a result, immunosuppressive drugs are frequently introduced. First-line immunotherapy typically involves high-dose oral corticosteroids such as prednisone or prednisolone, which can induce a rapid response within 2 to 4 weeks. To reduce reliance on steroids and improve long-term disease control, nonsteroidal immunosuppressants (NSISTs) are often used. These include antimetabolites (e.g., azathioprine, mycophenolate mofetil, methotrexate, and cyclophosphamide) and calcineurin inhibitors (e.g., tacrolimus and cyclosporine). While NSISTs may be used as standalone treatments, they usually take 6 to 9 months to produce noticeable effects. Immunomodulatory therapies, including intravenous immunoglobulin (IVIg) and plasmapheresis (PLEX), are typically reserved for acute exacerbations or myasthenic crises. They are also employed as chronic treatments in patients who cannot tolerate or do not respond to standard immunosuppressants. Although traditional immunosuppressive strategies can help manage symptoms, achieving long-term, stable remission remains difficult. Additionally, about 15% of patients are considered treatment-refractory, meaning they either fail to respond to or cannot tolerate multiple immunosuppressive options. These patients often face the dual challenge of persistent symptoms and the adverse effects of long-term immunosuppression. Learn more about the myasthenia gravis disease market @ Myasthenia Gravis Treatment Medications The myasthenia gravis treatment market is well-established, with multiple approved drugs for myasthenia gravis, including SOLIRIS, ULTOMIRIS, RYSTIGGO, ZILBRYSQ, and VYVGART, among others. Alexion Pharmaceuticals' SOLIRIS is a monoclonal antibody that targets and inhibits complement protein C5, thereby blocking the formation of the terminal complement complex. This action helps reduce complement-driven hemolysis in PNH and thrombotic microangiopathy in aHUS. Although its exact mechanism in gMG and NMOSD is not fully known, it is believed to decrease complement complex accumulation. Between 2017 and 2023, SOLIRIS gained regulatory approvals in Japan, the US, and the EU for treating gMG, including pediatric indications in Japan. ULTOMIRIS (ravulizumab), also from Alexion Pharmaceuticals, is the first long-acting C5 inhibitor, offering rapid, complete, and sustained suppression of complement activity. It binds to C5, preventing its cleavage and subsequent formation of the membrane attack complex (C5b-9). ULTOMIRIS is effective in managing terminal complement-mediated hemolysis in PNH and thrombotic microangiopathy in aHUS. Although the precise mechanism in gMG and NMOSD remains unclear, it is thought to reduce complement deposition at the neuromuscular junction and block aquaporin-4 antibody-mediated complement activation. It received approvals from the US FDA, EMA, and Japan's PMDA in 2022. Get an in-depth assessment on generalized myasthenia gravis medication for adults @ ULTOMIRIS vs SOLIRIS for Myasthenia Gravis UCB Biopharma's RYSTIGGO is a subcutaneously administered, humanized monoclonal antibody that binds with high affinity to the human neonatal Fc receptor (FcRn). It received regulatory approval from the US FDA and Japan's PMDA in 2023, followed by the EC in January 2024. ZILBRYSQ, also developed by UCB Biopharma, is the first once-daily subcutaneous peptide-based inhibitor specifically targeting complement protein C5. It works by blocking C5 cleavage and the formation of the terminal complement complex C5b-9. Although its precise action in gMG remains uncertain, it is thought to limit C5b-9 accumulation at the neuromuscular junction. ZILBRYSQ gained approval from the US FDA, EMA, and PMDA in 2023. VYVGART, from Argenx, is a human IgG1 antibody fragment that targets FcRn, leading to a decrease in circulating IgG autoantibodies. It is the first FcRn blocker to receive regulatory approval. Argenx's VYVGART HYTRULO (also marketed as VYVDURA) combines efgartigimod alfa, an FcRn inhibitor, with hyaluronidase, an endoglycosidase, for treating adults with generalized myasthenia gravis. This formulation was approved by the US FDA and EMA in 2023 and by the PMDA in January 2024. Uncover the mechanism of FcRn inhibitor myasthenia gravis medication @ Myasthenia Gravis MoA On April 30, 2025, the FDA approved Johnson & Johnson's nipocalimab, branded as IMAAVY, as a new therapy for gMG. This approval puts IMAAVY among the list of approved drugs for myasthenia gravis treatment. The approval, which J&J says encompasses the widest eligible patient population with gMG, includes individuals aged 12 and above who test positive for AChR or anti-muscle-specific kinase (MuSK) antibodies. IMAAVY functions by inhibiting the FcRn protein, which plays a role in maintaining circulating IgG antibodies, key drivers in many autoimmune disorders. By blocking FcRn, IMAAVY significantly reduces harmful IgG autoantibodies while preserving the body's overall immune response, according to clinical data. J&J sees broader potential for IMAAVY beyond gMG, believing its mechanism of action could apply across multiple autoimmune conditions due to IgG's involvement in various diseases. The FDA's decision followed results from the ongoing Phase III Vivacity-MG3 trial, which evaluates IMAAVY in combination with standard care versus placebo and standard care in 199 adult gMG patients, including 153 antibody-positive individuals. Additionally, J&J is conducting a Phase II/III pediatric trial called Vibrance, where IMAAVY, combined with standard care, achieved its primary goal by reducing total serum IgG levels by 69% over 24 weeks. J&J acquired IMAAVY through its USD 6.5 billion acquisition of Momenta Pharmaceuticals in 2020, with the FcRn inhibitor myasthenia gravis serving as the centerpiece of that deal. The company is aiming for blockbuster status, forecasting peak annual sales of over USD 5 billion for the myasthenia gravis medication.
