Brief Summary:
This is a Phase I study to assess the safety and MTD of paclitaxel + ribociclib (LEE011) in patients with Rb+, advanced breast cancer. Dose escalation will be performed using standard 3 + 3 dosing strategy. The starting dose of ribociclib (LEE011) is 200 mg once daily; dose escalation proceeds in 200 mg increments up to a maximum of 600 mg. Dose-limiting toxicities (DLT) will be based upon first-cycle toxicity.

Exclusion Criteria

Hormonal therapy must be discontinued at least 24 hours prior to starting study treatment.
  • Patient is unable to have a biopsy of a metastatic site for Rb testing, because the biopsy is felt to be too invasive or risky by the treating physician.

The following uses of corticosteroids are permitted: single doses, topical application (e.g., for rash), inhaled sprays (e.g., for obstructive airway diseases), eye drops or local injections (e.g., intra-articular).
  • Patient is currently receiving warfarin or other coumarin-derived anticoagulant for treatment, prophylaxis or otherwise. Therapy with heparin, low molecular weight heparin (LMWH) or fondaparinux is allowed.

  • Women of child-bearing potential, defined as all women physiologically capable of becoming pregnant, unless they are using highly effective methods of contraception throughout the study and for 8 weeks after study drug discontinuation. Highly effective contraception methods include:
  • Total abstinence when this is in line with the preferred and usual lifestyle of the patient. Periodic abstinence (e.g., calendar, ovulation, symptothermal, post-ovulation methods) and withdrawal are not acceptable methods of contraception
  • Female sterilization (have had surgical bilateral oophorectomy with or without hysterectomy) or tubal ligation at least six weeks before taking study treatment. In case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow up hormone level assessment
  • Combination of any two of the following (a+b or a+c or b+c) Use of oral, injected or implanted hormonal methods of contraception or other forms of hormonal contraception that have comparable efficacy (failure rate <1%), for example hormone vaginal ring or transdermal hormone contraception Placement of an intrauterine device (IUD) or intrauterine system (IUS) Barrier methods of contraception: Condom or Occlusive cap (diaphragm or cervical/vault caps) with spermicidal foam/gel/film/cream/ vaginal suppository
  • In case of use of oral contraception, women should have been stable on the same pill before taking study treatment.
  • Note: Oral contraceptives are allowed but should be used in conjunction with a barrier method of contraception due to unknown effect of drug-drug interaction.
  • Women are considered post-menopausal and not of child bearing potential if they have had 12 months of natural (spontaneous) amenorrhea with an appropriate clinical profile (e.g. age appropriate, history of vasomotor symptoms) or have had surgical bilateral oophorectomy (with or without hysterectomy) or tubal ligation at least six weeks ago. In the case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow up hormone level assessment is she considered not of child bearing potential.
