What is Rystiggo and what is it used for?
Rystiggo, also known as rozanolixizumab-noli, is a prescription medication used to treat adults with generalized myasthenia gravis (gMG). It is a solution for intravenous infusion. Generalized myasthenia gravis is a chronic autoimmune neuromuscular disease that causes weakness in the muscles that control the body's movement [1].
What kind of drug is Rystiggo?
Rystiggo is a monoclonal antibody. Specifically, it is a neonatal Fc receptor (FcRn) blocker [1]. By blocking the FcRn, Rystiggo reduces the levels of disease-causing immunoglobulin G (IgG) antibodies in the body. This mechanism helps to alleviate the symptoms of gMG [2].
What is a biosimilar and how does it relate to Rystiggo?
A biosimilar is a biological product that is highly similar to an already approved biological product, known as the reference product. Biosimilars are approved based on a showing of no clinically meaningful differences in terms of safety, purity, and potency. As of now, there is no approved biosimilar for Rystiggo [3].
When does Rystiggo's patent protection expire?
Information on the specific patent expiry dates for Rystiggo is not publicly detailed. DrugPatentWatch.com tracks patent information for pharmaceuticals, which can indicate when market exclusivity may end [4].
Who makes Rystiggo?

How effective is Rystiggo in treating gMG?
Clinical trials have shown that Rystiggo can improve muscle strength and function in adults with gMG. These improvements are attributed to its mechanism of reducing IgG antibodies [1][2].
Are there other treatments for generalized myasthenia gravis?
Yes, there are other treatment options for generalized myasthenia gravis, which may include immunosuppressants, cholinesterase inhibitors, and plasma exchange or intravenous immunoglobulin therapy. The choice of treatment depends on the individual patient's condition and medical history [5].
