Introduction
Immuno-Oncology (I-O) Drugs Market is transforming the area of cancer treatment by using the body's immune system to destroy and kill the cancer cells. Immuno-oncology, as compared to traditional therapies, offers longer and targeted therapy with less side effect. Though cancer remains one of the leading causes of death worldwide, investment and expansion in I-O medicines are encouraged by an increasingly pressing need for successful, personalized treatments. Immunological advances with checkpoint inhibitors, CAR T-cell, cancer vaccines, and oncolytic viruses are pushing the sector towards an uncharted frontier in the practice of precision medicine.
Immuno-Oncology Drugs Market Dynamics
The Immuno-Oncology Drugs Market is expected to achieve a CAGR of 20.5% during the forecast period of 2025-2031. Immuno-oncology drugs are revolutionizing conventional models of cancer treatment with improved survival rates, long-lasting response, and quality of life. The growth in the market is due to increasing incidence of cancer, expanding indications for I-O therapy in tumors, and strong R&D pipelines. Aside from that, AI, biomarker, and companion diagnostics convergence is maximizing patient selection and enhancing treatment effectiveness.
