Brief summary

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).

Detailed description

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.

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.

Phase 1: Number of Participants With Hypersensitivity and Neurotoxicity

Time frame: Baseline up to Month 36

Population: Explanation of how the number of participants for analysis was determined. Includes whether analysis was per protocol, intention to treat, or another method. Also provides relevant details such as imputation technique, as appropriate.~Safety population was defined as all participants who received at least 1 dose of any study drug.

Phase 2: Progression-Free Survival (PFS)

PFS is defined as the time from the date randomization for Phase 2 participants to the date of first documented progressive disease (PD) or death as assessed by the investigator using both RECIST 1.1 criteria and CA-125 criteria. PD is defined as 20% increase in the sum of the longest diameter of target lesions for measurable neoplastic disease or CA-125 criteria with elevated (\>70 units/mL) levels on 2 occasions. CA 125 progression for participants with normal CA 125 levels is defined as a CA 125 level \> 2 times the upper limit of normal and for participants with elevated values during the trial, is defined as a CA 125 level greater than 2 times the nadir value of CA 125.

Time frame: At the end of Cycle 2 and at the completion of every 2 cycles until PD was documented or up to data cut-off: 12 August 2014 (approximately 24 months)

Population: The modified intent-to-treat (mITT) population was defined as all participants who were randomized and received at least 1 dose of any study drug. For a participant that has not progressed and has not died or has started the alternate therapy, PFS is censored at the last response assessment that is stable disease (SD) or better.

Phase 1: Combined Best Overall Response Rate (ORR) in Participants With Recurrent Ovarian Cancer or Breast Cancer

Combined objective response rate is defined as the percentage of participants with Complete Response (CR) + Partial Response (PR) as assessed by the investigator according to Response Evaluation Criteria in Solid Tumors (RECIST) criteria 1.1 or response by Cancer antigen (CA) 125 criteria. According to RECIST: CR is defined as disappearance of all target lesions and PR is defined as 30% decrease in the sum of the longest diameter of target lesions. CA 125 response criteria is defined as either: A 50% decrease from 2 initially elevated samples; the sample demonstrating the 50% decrease must have been confirmed by a fourth sample 28 days later (a total of 4 samples required) or A serial decrease of \> 75% over 3 samples; the third sample was to be obtained 28 days after the second (a total of 3 samples required).

Time frame: At the end of Cycle 2 and at the completion of every 2 cycles until PD was documented or up to data cut-off: 12 August 2014 (approximately 24 months)

Population: Response evaluable population was defined as all participants who were randomized and had measurable disease according to RECIST or assessable disease by CA-125 criteria, who received at least 1 dose of any study drug, and who had at least 1 available post-Baseline response assessment as per either RECIST or CA-125 criteria.

CA 125 response criteria is defined as either: A 50% decrease from 2 initially elevated samples; the sample demonstrating the 50% decrease must have been confirmed by a fourth sample 28 days later (a total of 4 samples required) or A serial decrease of \> 75% over 3 samples; the third sample was to be obtained 28 days after the second (a total of 3 samples required).

Time frame: At the end of Cycle 2 and at the completion of every 2 cycles until PD was documented or up to data cut-off: 12 August 2014 (approximately 24 months)

Population: Response evaluable population was defined as all participants who were randomized and had measurable disease according to RECIST or assessable disease by CA-125 criteria, who received at least 1 dose of any study drug, and who had at least 1 available post-Baseline response assessment as per either RECIST or CA-125 criteria.

Phase 2: Duration of Response (DOR)

DOR was defined as the time from the date of first documentation of a response to the date of first documentation of PD or the last response assessment that is stable disease (SD) or better for a participant who started alternate therapy without progression. PD is defined as 20% increase in the sum of the longest diameter of target lesions for measurable neoplastic disease or per CA-125 criteria with elevated (\>70 units/mL) levels on 2 occasions. CA 125 progression for participants with normal CA 125 levels is defined as a CA 125 level \> 2 times the upper limit of normal and for participants with elevated values during the trial, is defined as a CA 125 level greater than 2 times the nadir value of CA 125. A responder that did not experience disease progression is censored at the last response assessment that is SD.

Time frame: Up to data-cut off: 12 August 2014 (approximately 24 months)

Population: Participants from Response evaluable population, all participants who were randomized and had measurable disease according to RECIST 1.1 or assessable disease by CA-125 criteria, who received at least 1 dose of any study drug, and who had at least 1 available post-Baseline response assessment per RECIST 1.1 or CA-125 criteria, who were responders.
