Brief Summary:

This is an open label, randomized, multicenter, international phase II study for premenopausal patients with hormone receptor positive, HER2 negative metastatic or locally advanced breast cancer. Patients will be randomized to receive either palbociclib + exemestane + OFS (Arm 1) or exemestane +OFS (Arm 2).

Treatment will be continued until disease progression, unacceptable toxicities, or withdrawal of consent.

Condition or disease Intervention/treatment Phase
Metastatic Breast Cancer Drug: Palbociclib Drug: Exemestane Drug: Goserelin Phase 2

Detailed Description:

There is a strong in-vitro and clinical evidence suggesting that the dual inhibition of CDK 4/6 and ER signaling is a highly effective therapeutic strategy in HR+ MBC. With the unprecedented success of palbociclib in PALOMA-1 trial, several phase 2 and 3 trials are underway to evaluate this agent (and other CDK4/6 inhibitors as well) in the different clinical scenarios of HR+ breast cancer [28].The vast majority of these trials -if not all- are testing these novel agents in postmenopausal patients, which would render the clinical experience of these agents restricted to postmenopausal women (median age was 62 years in PALOMA-1 trial) The scarcity of clinical trials addressing endocrinal therapy in premenopausal women with MBC is, at least in part, related to the fact that the majority of women in western countries are diagnosed with breast cancer during their postmenopausal life. However the situation is rather different in many countries, including those in the Middle East region, where the median age of women diagnosed with breast cancer is below 50 years, and where approximately 50% of these patients are still menstruating.

This study will be the first to explore the therapeutic effects of palbociclib when combined with exemestane and ovarian function suppression (OFS) in premenopausal with hormone receptor positive and HER2 negative MBC, and how it will compare to the classic approach of using OFS plus an aromatase inhibitor.

Layout table for eligibility information
Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   Female
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  1. Adult women (≥ 18 years of age) with metastatic or locally advanced breast cancer (histologically or cytologically proven diagnosis of adenocarcinoma of the breast) not amenable to curative treatment by surgery or radiotherapy.
  2. ER positive tumour: Histological or cytological confirmation of estrogen and/or progesterone-receptor positive, as determined by routine IHC. Positivity is defined as ≥1% positive stained cells. The receptor status determined by utilizing an assay consistent with local laboratory standards.
  3. HER2 negative breast cancer as confirmed by IHC, SISH or FISH.
  4. Premenopausal women : (definition of a real menopause is not a simple task in these relatively young women, owing to the potential effect of prior chemotherapy and /or endocrinal therapy particularly OFS) defined either by:

    i. Any age below 40 years , irrespective to E2 level or menstrual history ii. If the woman had a menstrual period any time within the last 12 months iii. If the woman has amenorrhea of more than 12 months (in the absence of chemotherapy or ovarian function suppression) that is associated with serum hormone levels that are NOT in the postmenopausal range (either estradiol (E2) < 30 pg/mL and follicle-stimulating hormone (FSH) < 20 mU/mL OR E2 ≥ 30 pg/mL and FSH ≥ 20 mU/mL) [30].

  5. Secondary hormonal resistance to tamoxifen or endocrinal sensitive metastatic disease i. Secondary hormonal resistance is defined as recurrence after 24 months from the start of adjuvant tamoxifen treatment or within 12 months from the end of the 5 years of adjuvant Tamoxifen ii. Endocrinal sensitive disease is defined as recurrence after 12 months from the end of adjuvant tamoxifen treatment or de novo metastatic disease
  6. Measurable disease according to RECIST or bone-only metastases. Previously irradiated lesions are deemed measurable only if progression is documented at the site after completion of radiation.

    i. Patients must either have at least one lesion that can be accurately measured; OR ii. Patients have bone lesions: lytic or mixed (lytic + sclerotic) in the absence of measurable disease as defined above.

  7. ECOG Performance Status 0, 1, & 2.
  8. Resolution of all acute toxic effects of prior therapy or surgical procedures to National Cancer Institute (NCI) CTCAE Grade 1 (except alopecia or other toxicities not considered a safety risk for the patient).
