Biosimilars | Market Events and Forecast | Neurology | 2025
In 2023, sales of branded MAb biologics in neurology exceeded $10 billion in the major pharmaceutical markets (United States, EU5, and Japan). Throughout our 2023-2033 forecast period, the reference brands Ocrevus (ocrelizumab) and Kesimpta (ofatumumab) are set to lose patent protection, and biosimilars will enter the market and erode both patient share and drug prices. We present our forecasts for these key reference brands and their biosimilars by molecule and country / region.
