This is an open-label, multicenter study with a nonrandomized Phase 1 portion and an open-label, randomized, Phase 2 portion evaluating MLN8237 in combination with weekly paclitaxel in adult female participants with advanced breast cancer (Phase 1 portion only) and recurrent ovarian cancer (both Phase 1 and Phase 2 portions).
The drug tested in this study was called alisertib. Alisertib was tested to treat people who have ovarian and breast cancer. This study looked at safety, any anti-tumor effect, and it also determined a recommended dose of alisertib plus paclitaxel to take into further studies. Pharmacokinetic blood samples were studied to characterize any effects on the concentration of each of the drugs when administered together. The study enrolled 191 patients. Participants with Breast Cancer and Ovarian Cancer received one of the following escalating doses of alisertib in combination with paclitaxel in the Phase 1 lead-in portion of the study: * Alisertib 10 mg BID + Paclitaxel 80 mg/m\^2 * Alisertib 20 mg BID + Paclitaxel 80 mg/m\^2 * Alisertib 20 mg BID + Paclitaxel 60 mg/m\^2 * Alisertib 30 mg BID + Paclitaxel 60 mg/m\^2 * Alisertib 40 mg BID + Paclitaxel 60 mg/m\^2 * Alisertib 50 mg BID + Paclitaxel 60 mg/m\^2 Once the maximum tolerated dose (MTD)/ recommended phase 2 dose (RP2D) was determined, participants were randomized to receive the following treatments in the Phase 2 portion of the study: * Alisertib 40 mg BID + Paclitaxel 60 mg/m\^2 * Paclitaxel 80 mg/m\^2 This multi-center trial was conducted in the United States, Poland and France. The overall time to participate in this study was approximately 5 years. Participants made multiple visits to the clinic, and who did not experience disease progression (PD) were followed off-treatment once every 8 weeks until the occurrence of 110 progression-free survival (PFS) events.

Phase 1: Maximum Tolerated Dose (MTD) and Recommended Phase 2 Dose (RP2D) for Alisertib in Combination With Paclitaxel
The MTD is defined as the dose range at which ≤ 1 of 6 evaluable participants experience dose limiting toxicities (DLT). DLT was evaluated according to National Cancer Institute's Common Terminology Criteria for Adverse Events (NCI CTCAE) version 4.02 and was defined as any of the following events: 1. Grade 4 neutropenia and thrombocytopenia lasting ≥7 consecutive days; 2. Grade 4 neutropenia with fever and/or infection; 3. Platelet count \<10,000/mm\^3; 4. Grade 3 thrombocytopenia with bleeding; 5. Any other ≥Grade 3 nonhematologic toxicity, with following exceptions: ≥Grade 3 nausea/emesis, ≥Grade 3 diarrhoea, Grade 3 fatigue, Grade 3 nonhematological toxicity that could be controlled to ≤Grade 2 with appropriate treatment; 6. Other alisertib-related nonhematologic toxicities ≥Grade 2 that, in opinion of investigator, required a dose reduction or discontinuation of therapy with alisertib.
Time frame: Cycle 1 (Up to 28 days)
Phase 1: MTD and RP2D for Paclitaxel in Combination With Alisertib
The RP2D is the maximum tolerated dose (MTD) or less. The MTD is defined as the dose range at which ≤ 1 of 6 evaluable participants experience dose limiting toxicities (DLT) within the first 28 days of treatment (end of cycle 1).
Time frame: Cycle 1 (Up to 28 days)
Phase 1: Number of Participants With Adverse Events (AEs) and Serious Adverse Events (SAEs)
An Adverse Event (AE) is defined as any untoward medical occurrence in a clinical investigation participant administered a drug; it does not necessarily have to have a causal relationship with this treatment. A Serious Adverse Event (SAE) A serious is any experience that suggests a significant hazard, contraindication, side effect or precaution that: results in death, is life-threatening, required in-patient hospitalization or prolongation of existing hospitalization, results in persistent or significant disability/incapacity, is a congenital anomaly/birth defect or is medically significant.
Time frame: First dose to 30 days past last dose (Up to 36 Months)
Phase 1: Number of Participants With Clinically Significant Laboratory Values
Abnormal clinical laboratory values (serum chemistry, hematology and urinalysis) were reported as AEs if they were considered by the investigator to be a clinically significant change from Baseline or led to premature discontinuation of study treatment, dose modification, or other therapeutic intervention.
Time frame: First dose to 30 days past last dose (Up to 36 Months)
Phase 1: Number of Participants With Clinically Significant Vital Sign Findings
Vital signs (blood pressure, pulse rate, and oral temperature) measurements were collected throughout the study.
