The application dimension of the Broluzumab Biosimilars market is divided into three primary therapeutic areas: oncology, rheumatology, and dermatology. Oncology, accounting for roughly 70 % of total sales, encompasses both solid‑tumor indications (e.g., non‑small cell lung cancer) and hematologic malignancies (e.g., diffuse large B‑cell lymphoma). This dominance reflects the high prevalence of cancer patients requiring long‑term infusion therapy and the aggressive pricing pressure that drives biosimilar adoption. Rheumatology contributes about 20 % and includes autoimmune conditions such as rheumatoid arthritis and psoriatic arthritis, where Broluzumab biosimilars serve as maintenance agents after conventional DMARD failure. Dermatology, representing the remaining 10 %, targets severe plaque psoriasis and related skin disorders, where the drug’s mechanism of action offers a differentiated benefit over older biologics. Together, these application segments form the core of the Broluzumab Biosimilars segmentation framework, each adding distinct volume and margin characteristics that shape the overall market size.
