Study Summary

This trial is studying a combination of drugs as a neoadjuvant (before surgery) treatment for hormone receptor-positive, HER2-negative breast cancer.

Who is the study for?
This trial is for adults at least 19 years old with advanced stage ER+ and/or PR+, HER2- breast cancer, who can take oral medication and have normal organ function. It's not for those previously treated with CDK inhibitors, allergic to similar compounds, with significant liver disease or absorption issues, unstable heart conditions, pregnant/breastfeeding women, HIV-positive on antiretrovirals, men, those with known metastasis or taking certain other drugs.Check my eligibility
What is being tested?
The study tests Palbociclib (a CDK inhibitor) combined with letrozole (an aromatase inhibitor) +/- Goserelin (GnRH analogue), as a pre-surgery treatment to improve responses in hormone receptor positive breast cancer patients. The goal is better surgical outcomes without chemotherapy.See study design
What are the potential side effects?
Palbociclib may cause low white blood cell counts increasing infection risk; fatigue; nausea; sore mouth; hair thinning; diarrhea and potential liver problems. Letrozole side effects include hot flashes; joint pain and osteoporosis while Goserelin can cause menopause-like symptoms.

The following drugs will be taken for six cycles: Palbociclib at a dose of 125 mg should be taken by mouth with food on 21 days and 7 days off schedule (meaning: on Days 1-21 of each 28-day cycle). Letrozole should be taken daily by mouth, every day of each 28-day cycle, at a dose of 2.5 mg. Goserelin is given as subcutaneous injection every 28 days at a dose of 3.6 mg. It is to be given on Day 1 of each cycle. Goserelin will only be administered to pre-menopausal subjects.
