High Cost of Treatment

Several challenges hinder the expansive potential of the immuno-oncology market. Chief among these is the occurrence of drug resistance, wherein cancer cells evolve during treatment, impeding T-cell infiltration into tumors. The inability to accurately predict treatment efficacy and patient response, alongside the necessity for additional biomarkers, poses significant constraints. The emergence of resistance to cancer immunotherapies, coupled with the lack of optimized clinical study designs to ascertain efficacy, further exacerbates these limitations. Moreover, the high costs associated with treatment contribute to the market's restrictions. Addressing these challenges is essential to unlock the full potential of immuno-oncology and overcome barriers to market growth.


Recent Advancement in Technology

Recent advancements highlighting the role of the immune system in biological therapies, particularly those targeting the tumor microenvironment, present a significant opportunity for the immuno-oncology market. Progress in utilizing immune cells, T cells pivotal in cell-mediated immunity, has demonstrated success in clinical trials for treating malignant tumors. With cancer immunotherapies focusing on T lymphocytes emerging as a primary strategy, recent studies underscore the potential of T cells in enhancing cancer treatments, including checkpoint blockade, adoptive cellular therapy, and cancer vaccinology. Cancer vaccines, which bolster the immune system to combat cancer cells, create a promising avenue for growth within the immuno-oncology market.

  • In April 2024, the BioMed X Institute in Heidelberg initiated a new immuno-oncology research project in collaboration with Merck, aiming to explore novel avenues in cancer treatment.

In November 2023, Mural Oncology commenced operations with the objective of advancing a pipeline of innovative engineered cytokine immunotherapies.
