Brief summary:
To determine the dose-limiting toxicity (DLT) and maximum tolerated dose (MTD) of MLN8237 when given by mouth (PO) for a minimum of 7 and a maximum of 21 consecutive days, followed by a 14-day recovery period.

Detailed description:
The drug tested in this study is called alisertib. Alisertib is being tested to treat people who have advanced 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 87 participants. Participants were enrolled in one of 3 treatment groups:

* Powder-in-Capsule (PIC) Dose Escalation (alisertib 5, 10, 20, 40, 80, 110 or 150 mg PIC , once daily (QD) for 7 days (D),or alisertib 25 mg, PIC, orally, QD 14D, or alisertib 25, 50 or 70 mg, PIC, orally, QD 21D, or alisertib 50 or 60 mg, PIC, orally, twice daily (BID) 7D, alisertib 40 mg, PIC, orally, BID 14D
* ECT Dose Escalation (alisertib 10 or 20 mg, Enteric-coated Tablets (ECT), orally, QD for 7 to 21 days
* Relative Bioavailability (alisertib 40 mg ECT or PIC, orally, BID 7D in cycle 1, followed by alisertib 40 mg in the opposite formulation (PIC or ECT) orally, BID 7D in cycle 2, followed by alisertib 50 mg PIC orally, BID 7D in each additional All participants received treatment 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 1011 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.

Arms: arm 1: Alisertib 5, 10, 20, 40, 80, 110 or 150 mg, Powder-in-Capsule (PIC) formulation, orally, once daily (QD) for 7 to 21 days followed by a 14--day recovery period in each cycle until disease progression or unacceptable alisertib--related toxicity (up to 51 cycles). arm 2: Alisertib 10 or 20 mg, Enteric-coated Tablet (ECT) formulation, orally, once daily (QD) for 7 days followed by a 14--day recovery period in each cycle until disease progression or unacceptable alisertib--related toxicity (up to 2 cycles). arm 3: Alisertib 40 mg ECT or PIC formulation, orally, twice daily (BID) for 7 days followed by a 14--day recovery period in cycle 1, followed by alisertib 40 mg in the opposite formulation (PIC or ECT) orally, twice daily (BID) for 7 days followed by a 14--day recovery period in cycle 2, followed by alisertib 50 mg PIC formulation orally, twice daily (BID) for 7 days followed by a 14--day recovery period in each cycle until disease progression or unacceptable alisertib--related toxicity (up to 9 cycles).
Interventions: intervention 1: Alisertib
Intervention descriptions: intervention 1: Alisertib (MLN8237) will be supplied in capsules of 5 or 25 mg and will be given on an empty stomach, with patients remaining nothing by mouth except for water and prescribed medications for 2 hours before and 1 hour after each dose.
