NCT03096847

Brief Summary

This was a national, multi-center, open-label, phase IIIb trial to determine the efficacy and safety of treatment with ribociclib (LEE011) plus letrozole in patients with HR+, HER2-negative advanced (recurrent or metastatic) breast cancer. Patients were treated with daily doses of 600 mg ribociclib (3-weeks-on/1-week-off schedule) in combination with 2.5 mg letrozole daily (continuous dosing). Dose adjustments (dose reduction or interruption) according to safety findings were allowed.

ribociclib + letrozole cohort B2

EXPERIMENTAL

ribociclib + letrozole cohort B2 - premenopausal women or perimenopausal women or postmenopausal women, or men; pre-treated. All patients received ribociclib 600mg p.o. daily + Letrozole 2.5 mg p.o. daily. Premenopausal patients additionally received goserelin 3.6 mg i.m. monthly

Drug: ribociclibDrug: letrozoleDrug: goserelin

Interventions

All patients with oestrogen receptor positive advanced or metastatic breast cancer were treated with oral ribociclib at a dose of 600mg daily and oral letrozole 2.5mg daily. The study treatment for an individual patient began on Study Day 1 and continued until 80 weeks after the last patient enrolled the study or until disease progression, unacceptable toxicity, death or early discontinuation from the study for any other reason, whichever occured first.

  • Women and men with advanced (locoregionally recurrent or metastatic) breast cancer not amenable to curative therapy.
  • Patient has a histologically and/or cytologically confirmed diagnosis of estrogen-receptor positive and/or progesterone receptor positive and HER2-negative breast cancer by local laboratory. Local pathology is sufficient for assessment.
  • Patient must have either:

  • Patient has a known hypersensitivity to any of the excipients of ribociclib or letrozole
  • Patients with current inflammatory breast cancer.
  • Patient has received \> 1 chemotherapy for the treatment of advanced/metastatic breast cancer
  • Patient has received \> 2 endocrine therapies for the treatment of advanced/metastatic breast cancer
  • Patient has central nervous system (CNS) involvement. If patient is fulfilling the following 3 criteria she/he is eligible for the trial.
  • completed prior therapy (including radiation and/or surgery) for CNS metastases ≥ 28 days prior to the start of study and
