This is an open-label, multicenter, phase 1 study of MLN8237 in participants with advanced hematological malignancies for whom there are limited standard treatment options.
The drug being tested in this study is called alisertib. Alisertib is being tested to treat people who have advanced hematological malignancies. This study determined the dose-limiting toxicity, maximum tolerated dose, safety and pharmacokinetics (how the drug moves through the body) for alisertib when given once or twice a day for 7 to 21 days. This open label study enrolled 58 patients. Participants were enrolled in one of 3 treatment groups: * Part 1: Powder-in-Capsule (PIC) Dose Escalation (alisertib 25 mg PIC, orally twice daily \[BID\] on Day 1 \[loading dose\] and then alisertib 25 or 35 mg PIC once daily \[QD\] for 21 days (D), or alisertib 35, 45, 65 or 90 mg PIC, orally, QD for 14D) in 28-day cycles * Part 1: Enteric-coated Tablet (ECT) Dose Escalation (alisertib 40 mg, ECT, orally, QD for 14D or alisertib 30, 40 or 50 mg, orally, BID for 7D) in 28-day cycles * Part 2: Participants with Peripheral T-cell Lymphoma (PTCL) (alisertib 50 mg ECT, orally, BID for 7D) in 21-day cycles All participants received treatment for 12 months or until their disease progressed or they experienced unacceptable alisertib-related toxicity. This multi-center trial was conducted in the United States. The overall time to participate in this study was 422 days. Participants made multiple visits to the clinic, including a final visit 30 days after receiving their last dose of alisertib for a follow-up assessment.

Number of Participants With Dose-Limiting Toxicity (DLT)
DLT was evaluated according to the National Cancer Institute's Common Terminology Criteria for Adverse Events (NCI CTCAE) version 3.0 and was defined as any of the following events related to therapy with alisertib:1. Grade 4 neutropenia lasting ≥7 consecutive days, 2. Grade 4 neutropenia with fever and/or infection 3. Platelet count \<25,000/mm\^3 4. Grade 3 or greater nausea and/or emesis despite use of optimal antiemetic prophylaxis 5. Grade 3 or greater diarrhea despite maximal supportive therapy with loperamide 6. Any other Grade 3 or greater nonhematologic toxicity, with the following exceptions: Grade 3 arthralgia/myalgias, Any grade of alopecia, Brief (\<1 week) Grade 3 fatigue 7. Treatment delay of \>21 days due to failure of adequate hematologic or non-hematologic recovery from previous cycle of treatment 8. Other alisertib related non-hematologic toxicities ≥Grade 2 that, in the opinion of the investigator required a dose reduction or discontinuation of therapy with alisertib.

Best Overall Response Rate Based on Investigator's Assessment
Best overall response rate is defined as the percentage of participants with complete response (CR) or partial response (PR) as assessed by the Investigator using International Working Group (IWG) Criteria. CR is defined as the disappearance of all evidence of disease and the definition for PR includes at least a 50% decrease in sum of the product of the diameters and no new lesions.
Time frame: Baseline and every 2 cycles up to Month 12 until disease progression, 30 days after end of treatment (up to 422 days)
Duration of Response (DOR)
DOR is defined as the time from the date of first documentation of a response (either CR or PR) to the date of first documentation of progressive disease (PD) according to International Working Group (IWG) criteria. CR is defined as the disappearance of all evidence of disease and the definition for PR includes at least a 50% decrease in sum of the product of the diameters and no new lesions. PD is defined as any new lesion or increase by \>50% of previously involved sites from nadir.
Time frame: Baseline and every 2 cycles up to Month 12 until disease progression, 30 days after end of treatment (up to 422 days)
Number of Participants With Polymorphisms in Gene Encoding Enzyme UGT1A1
One peripheral blood sample (approximately 4 mL) was to be obtained on Day 1 of Cycle 1 prior to the first dose of alisertib to genotype participants for polymorphisms in UGT1A1 because UGT1A1 is one of the enzymes responsible for glucuronidation of alisertib, which is expected to contribute to the clearance of alisertib. wt=wild type. \*28=polymorphism in the promoter region of a UGT1A1 allele resulting in reduced UGT1A1 expression. Not determined = blood sample was not evaluable.
Time frame: Cycle 1 Day 1 predose
Number of Participants With Polymorphisms in Aurora A Kinase
Time frame: Cycle 1 Day 1 predose
