I have multiple autoimmune disorders including PMR but not GCA.

Actemra works in the same way that Kevzara works. Actemra was the first IL-6 inhibitor and has been used for RA and other autoimmune disorders for a long time. Actemra was FDA approved for GCA in 2017. I started Actemra in 2019 before Kevzara was FDA approved for PMR. My rheumatologist believed that Actemra "should work" for PMR after research showed that it worked for GCA.

" The high cost of clinical trials combined with the availability of lower-cost biosimilars for Actemra makes it an unlikely path for the drug's manufacturer, Genentech, to seek FDA approval for polymyalgia rheumatica (PMR). "

It is doubtful that Genetech will seek an additional FDA approval for PMR because it costs so much money to do the clinical trials to get FDA approval. Since Actemra is no longer patented, there are already biosimilars on the market that compete with Actemra at a lower cost. Research and development costs for medications to get the initial FDA approval for a specific diagnosis are astronomical.
