In comments submitted this week, PhRMA urged the Centers for Medicare & Medicaid Services (CMS) to withdraw its proposed national coverage determination (NCD) for monoclonal antibodies (mAbs) for the treatment of Alzheimer’s disease. The proposed policy would set a dangerous precedent of CMS severely restricting patient access to FDA-approved medicines, putting in place barriers to treatment options for a devastating illness, especially for patients in underserved communities. We urge CMS to instead provide Medicare patients with appropriate and timely access to Alzheimer’s disease treatments.
