Details and patient eligibility

About

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).

Full 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.

Enrollment: 191 patients

Sex: Female

Ages: 18+ years old

Inclusion criteria

Each participant must meet all of the following inclusion criteria to be enrolled in the study:

• Female participants 18 years or older

• In the Phase 1 portion of the study, participants with breast cancer must have received treatment with at least 1 but no more than 4 prior chemotherapy regimens not including regimens received in the neoadjuvant and/or adjuvant setting
• Participants with breast cancer must have measurable disease per Response Evaluation Criteria in Solid Tumors (RECIST) 1.1
• No antineoplastic therapy or radiotherapy within 3 weeks before enrollment (2 weeks for regimens with recovery expected within 7 to 14 days) and recovered from toxicities of prior therapy (except alopecia); the participant must have recovered from all treatment-related toxicities and must have evidence of progressive disease (PD) or persistent disease
• Eastern Cooperative Oncology Group (ECOG) performance status 0 or 1
• Adequate bone marrow, liver and renal function
• Postmenopausal at least 1 year, OR Surgically sterile, OR If childbearing potential, agree to 2 effective methods of nonhormonal contraception, or agree to completely abstain from heterosexual intercourse
• Able to provide written informed consent
• Willing to comply with scheduled visits, treatment plan, laboratory tests and other trial procedures

Specific Inclusion Criteria for participants with Recurrent Ovarian, Fallopian Tube or Peritoneal Cancer:

• Prior treatments must have included a platinum and a taxane; the most recent treatment need not be a platinum-containing or taxane-containing regimen
• Disease must have recurred ≤ 12 months after discontinuation of platinum therapy
• Participants who previously received weekly taxane are potentially eligible, provided that they did not progress during therapy or within 3 months of completing therapy
• Participants with platinum-refractory disease, as defined by progression during primary or subsequent platinum-based therapy or persistent radiographic disease after primary or subsequent platinum-based therapy, will be included
• Participants must have measurable disease in target lesions or assessable disease (defined by cancer antigen-125 - CA-125 per protocol), and disease progression per Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 or modified Gynecologic Cancer Intergroup (GCIG) CA-125 criteria

Exclusion criteria

Participants meeting any of the following exclusion criteria are not to be enrolled in the study:

• Prior treatment with an Aurora A-targeted agent (including MLN8237)

• Known hypersensitivity to Cremophor® EL, paclitaxel or its components
• Prior history of ≥ Grade 2 neurotoxicity or any toxicity requiring discontinuation from taxane chemotherapy that is not resolved to ≤ Grade 1
