Within the Types segment, targeted drugs for multiple myeloma are classified into five principal families: proteasome inhibitors (e.g., bortezomib, carfilzomib), immunomodulatory drugs (IMiDs such as lenalidomide, pomalidomide), monoclonal antibodies (including daratumumab, elotuzumab), BCL‑2 inhibitors (venetoclax), and cellular therapies (CAR‑T cell products like idecabtagene vicleucel). Each family contributes distinct mechanisms of action that address specific disease pathways, influencing prescribing patterns and pricing dynamics. Proteasome inhibitors dominate early‑line regimens, while IMiDs are pivotal across both frontline and maintenance settings. Monoclonal antibodies have reshaped combination protocols, capturing a sizable share of the relapsed/refractory market. BCL‑2 inhibitors, though niche, target high‑risk cytogenetic subpopulations, adding incremental volume. CAR‑T cell therapies, despite high upfront costs, are expanding rapidly in the relapsed/refractory segment, reflecting a shift toward personalized, durable responses. This typology clarifies how each drug class underpins the overall market valuation and informs strategic investment decisions.
