What Drivers Are Affecting Demand-Supply Dynamics In The Metastatic HR+/HER2- Breast Cancer Market?

The expanding adoption of hormone replacement therapy (HRT) is anticipated to propel the future growth of the metastatic HR+/HER2- breast cancer market. HRT is a medical intervention employed to supplement or replace hormones present at lower levels in the body, most commonly during menopause or in instances of hormone deficiencies. The rising prevalence of hormone replacement therapy (HRT) is attributed to its efficacy in enhancing treatment outcomes, its reduced side effects compared to conventional therapies, and advancements in precision medicine. Hormonal replacement therapy (HRT) can support individuals with metastatic HR+/HER2- breast cancer by alleviating menopausal symptoms associated with estrogen deficiency, such as hot flashes and vaginal dryness, without interfering with the effectiveness of endocrine therapies. This is because HRT primarily addresses hormone imbalances rather than directly targeting cancerous cells, thereby ensuring a better quality of life for patients undergoing cancer treatment. For example, data from October 2023, provided by the Health Professional Academy, a UK-based personalized health professional learning platform, showed that approximately 11 million hormone replacement therapy (HRT) prescriptions were issued in 2022/23, marking an almost 50% rise from the preceding year. Thus, the increasing application of hormone replacement therapy (HRT) is a key driver for the metastatic HR+/HER2- breast cancer market.

What Upcoming Trends Are Likely To Define The Future Path Of The Metastatic HR+/HER2- Breast Cancer Market?

Major companies within the metastatic HR+/HER2- breast cancer market are actively developing combination therapy to broaden their indications, extend market reach, and diversify treatment options. Combination therapy represents a therapeutic strategy that involves the concurrent use of two or more therapeutic agents, which may include chemotherapy, targeted therapy, immunotherapy, hormone therapy, or other modalities, to more effectively manage a medical condition. This approach aims to target different pathways, enhance the overall treatment response, and reduce the likelihood of conditions, such as cancer, developing resistance to any single treatment. For instance, in July 2023, Merck & Co., Inc., a US-based pharmaceutical company, announced findings from the Phase 3 KEYNOTE-756 trial. This study evaluated KEYTRUDA (pembrolizumab), an anti-PD-1 therapy, in conjunction with chemotherapy approved by the Food and Drug Administration, a US-based government agency. The trial successfully achieved its primary endpoint by significantly improving the pathological complete response (pCR) rate in patients with high-risk, early-stage ER+/HER2- breast cancer. KEYNOTE-756 stands as the first positive Phase 3 trial to demonstrate a statistically significant enhancement in the pCR rate with an immunotherapy regimen in the neoadjuvant setting for this specific patient population. The study assessed KEYTRUDA with chemotherapy as a neoadjuvant treatment, followed by adjuvant KEYTRUDA alongside endocrine therapy for high-risk, early-stage ER+/HER2- breast cancer.
