Kaiser Permanente Northern California seems to be treating Actemra and Kevzara as interchangeable with Actemra their preference, and Kevzara as a backup. I think this is becasue they get Actemra at lower cost. My rheumatologist says the cost to the patient is the same for either. Both corporations that produce these drugs offer a $15,000 annual subsidy if you have a condition for which the drug is FDA approved to treat. This can make the cost to the patient near zero. Actemra is approved for GCA (but not PMR) and Kevzara is approved for PMF (but not GCA).
