Step Therapy

ASRS opposes step-therapy protocols that require patients to try and fail certain treatments before allowing access to other, potentially more appropriate treatments. We are particularly concerned about step-therapy policies that require the off-label use of Avastin when branded drugs (Eylea® and Lucentis®) are available as it undermines the authority of the Food and Drug Administration.

The most appropriate course of treatment for a given medical condition depends on the patient’s unique clinical situation. While a particular drug or therapy might be generally considered appropriate for a condition, the presence of comorbidities, potential drug-drug interactions, or patient intolerances, for example, may necessitate the selection of an alternative drug as the first course of treatment. Step-therapy requirements interfere with medical decision-making and often delay getting patients the right treatment at the right time. For some patients, this could result in unrecoverable sight loss. 

Despite our long-standing opposition, the Centers for Medicare and Medicaid Services (CMS) in an August 7, 2018 memo to Medicare Advantage (MA) Organizations entitled “Prior Authorization and Step Therapy for Part B Drugs in Medicare Advantage,” rescinded its September 17, 2012 memo prohibiting MA plans from using step therapy for Part B drugs. If the controversial plan stands, Medicare Advantage plans would be allowed to utilize step-therapy protocols for physician-administered drugs covered under Medicare Part B beginning in 2019.

ASRS is actively and vigorously opposing this change as it undermines patient-physician decision-making and creates dangerous barriers and delays to effective care, especially for the sickest patients.
