Breast cancer is an ongoing ground for research as technology improves the way with which hormone-positive kind of cancer is handled. Of these, newer oral therapies are in the offing, which contains good treatment plans for patients with hormone-sensitive breast cancer. These new therapies act on certain hormonal signals, and hold or reverse cancer cells’ proliferation, frequently being more comfortable than other procedures.
This blog reviews new advances in oral hormone therapies and offers insights on how it functions, its advantages, and implications to future breast cancer treatment. By keeping abreast and enjoining ourselves with this integrate, powering into this critical evolution of cancer treatment.
What Are The Newer Oral Therapy in Breast Cancer Hormone-Positive?
Advancements in the treatment of hormone receptor-positive (HR+) breast cancer have led to the development of innovative oral therapies that offer patients more convenient and effective options. Here are some of the latest oral treatments making significant strides:
1. Oral Selective Estrogen Receptor Degraders (SERDs):
Traditional SERDs like fulvestrant require intramuscular injections, which can be inconvenient for patients. New oral SERDs have been developed to overcome this limitation, providing effective estrogen receptor antagonism in a more patient-friendly form.
- Giredestrant: An investigational oral SERD developed by Roche, giredestrant targets estrogen receptors in HR+ breast cancer. It has shown promise in clinical trials, with pivotal results expected in the coming years.

2. PI3K Inhibitors:
Mutations in the PIK3CA gene are common in HR+ breast cancer, leading to uncontrolled cell growth. PI3K inhibitors target this pathway, offering a tailored treatment approach for patients with these mutations.
- Inavolisib (Itovebi): Recently approved by the U.S. Food and Drug Administration (FDA) in October 2024, inavolisib is an oral PI3K inhibitor indicated for the treatment of PIK3CA-mutant breast cancer. Its approval was based on positive results from the INAVO120 trial, highlighting its efficacy in this patient population.

3. CDK4/6 Inhibitors:
These inhibitors disrupt the cell cycle, preventing cancer cells from proliferating. When combined with hormone therapy, they have become a standard treatment for HR+ breast cancer.
- Palbociclib, Ribociclib, Abemaciclib: These oral medications have been integrated into treatment regimens, improving progression-free survival rates for patients with advanced HR+ breast cancer.
4. mTOR Inhibitors:
Targeting the mTOR pathway, these inhibitors can overcome resistance to hormone therapy in HR+ breast cancer.
- Everolimus: An oral mTOR inhibitor, everolimus is used in combination with hormone therapy to treat advanced HR+ breast cancer, offering an additional line of defense against disease progression.
These newer oral therapies represent a significant advancement in the management of hormone-positive breast cancer, providing patients with more effective and convenient treatment options. Ongoing research continues to expand the arsenal of oral treatments, aiming to improve outcomes and quality of life for those affected by this disease.
