A Study of MLN8237, a Novel Aurora A Kinase Inhibitor, in Participants With Advanced Solid Tumors

Millennium Pharmaceuticals, Inc.87 enrolled

Overview

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.

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.

Interventions

AlisertibDRUG

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. Each dose will be given by mouth with 8 ounces of water for 7 to 21 consecutive days. A 14-day recovery period will follow each dosing period regardless of its duration.

Participants treated with fully human monoclonal antibodies must not have received treatment with such antibodies for at least 6 weeks, and those treated with chimeric monoclonal antibodies must not have received treatment with such antibodies for at least 4 weeks. Participants treated with noncytotoxic small molecule drugs (eg, tyrosine kinase inhibitors, such as Tarceva®, and hormonal agents, such as Femara®) must not have received treatment with these drugs for at least 2 weeks before the first dose of MLN8237 is given. * Male participants must use an appropriate method of barrier contraception (eg, condoms) and inform any sexual partners that they must also use a reliable method of contraception (eg, birth control pills) from the time of informed consent until 3 months after the last dose of study treatment. * Female participants must be postmenopausal, surgically sterilized, or willing to use reliable methods of birth control (eg, a hormonal contraceptive, an intrauterine device, diaphragm with spermicide, or abstinence) and inform male sexual partners that they must also use a reliable method of contraception (eg, condoms) from the time of informed consent until 3 months after the last dose of study treatment. * Willing and able to give written informed consent before the conduct of any study related procedure that is not part of normal medical care, and willing to comply with the protocol Exclusion Criteria: * Pregnant or lactating * Major surgery or serious infection within the 28 days preceding the first dose of study treatment * Life-threatening illness or uncontrolled medical illness unrelated to cancer * Ongoing nausea or vomiting of any severity * \> Grade 1 diarrhea * Known gastrointestinal (GI) disease or GI procedure that could interfere with the oral absorption or tolerance of MLN8237.

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 \>1 week due to failure of adequate hematologic or nonhematologic recovery from previous cycle of treatment 8. Other alisertib-related nonhematologic toxicities ≥Grade 2 that, in the opinion of the investigator, required a dose reduction or discontinuation of therapy with alisertib.

Change From Baseline in Alisertib Skin Punch Biopsy as Measured by Mitotic Index With PIC Once Daily for 7 Days (QD7D) Dosing

Mitotic index was defined as the mean number of mitotic cells per millimeter (mm) length of the basoepithelial layer (BEL). Mitotic cells were counted manually within the BEL of 4, 5 µM skin sections by staining with fluorescent-tagged antibodies specific to 2 mitotic markers-serine 10 phosphohistone H3 (pHistH3) and MPM2. Deoxyribonucleic acid (DNA) was stained with a fluorescent marker as well. A positive change from Baseline indicates improvement.

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 patients 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.

Time frame: Cycle 1 Day 1 predose

Best Overall Response Based on Investigator Assessment

Best overall response 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. According to RECIST: CR is defined as disappearance of all target and nontarget lesions and normalization of tumor marker level (if applicable); PR is defined as ≥30% decrease in the sum of the longest diameter of target lesions, taking as reference the baseline sum longest diameter, persistence of 1 or more nontarget lesion(s) and/or maintenance of tumor marker level above the normal limits.

Time frame: Beginning at the end of Cycle 2, every 2 cycles until progressive disease (PD); Participants who discontinue study drug before PD: Follow-Up (FU) every 8-12 weeks until PD or as per institutional practice (Up to 33.2 months)

Duration Of Response (DOR)

DOR is defined as the time from the date of first documentation of a confirmed response to the date of first documented PD. PD is defined as 20% increase in the sum of the longest diameter of target lesions.

Effect of Food on the Pharmacokinetics (PK) of Alisertib

The effects of food on the PK of alisertib were to be evaluated using the preferred alisertib regimen (unit dose and formulation) based on the results from the relative bioavailability study.

Time frame: Up to 6 months
