Given by the rising risk of cancer across the globe, there has been a surge in the demand for advanced targeted therapies. According to the Breast Cancer Facts and Statistics, in 2025, nearly 3,16,950 women will be diagnosed with invasive breast cancer. Therefore, to mitigate the growing concern of cancer, two drug targets specifically enzymes, such as CDK4 and CDK6, are presently identified to treat cancer particularly hormone receptor-positive and HER2-negative breast cancer.

These enzyme-based drugs interrupt the signals that stimulate the malignant cells proliferation, thereby killing cancer cells. Further, these inhibitor-based drugs can also be provided in combination with endocrine therapy to ensure high efficiency for targeting metastatic cancer. To date, three inhibitor drugs has been approved by the FDA, namely palbociclib (Ibrance®), ribociclib (Kisqali®), and abemaciclib (Verzenio®).

Considering the heightened demand, several industrial players are increasing their research initiatives to develop advance therapeutic drugs particularly inhibitor drugs. Furthermore, several clinical trials are currently ongoing to explore the use of therapeutic drugs in clinical settings to treat breast cancer subtypes specifically in pre-menopause and post-menopause patients. These ongoing initiatives are likely to make CDK4 / 6 inhibitors market immensely competitive and investible for a long term.
