a study of mln8237, a novel aurora a kinase inhibitor, in participants with advanced solid tumors

Conditions: Advanced Malignancies

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.

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.

Eligibility criteria:
inclusion criteria: * histologically or cytologically confirmed metastatic and/or advanced solid tumors (including lymphomas) for which no effective standard treatment is available * aged 18 years or more * eastern cooperative oncology group (ecog) performance status 0 or 1 * expected survival longer than 3 months from enrollment in the study * radiographically or clinically evaluable tumor; however, measurable disease as defined by (recist) criteria is not required for participation in this study * suitable venous access for the conduct of blood sampling for mln8237 pk * recovered from the reversible effects of prior antineoplastic therapy (with the exception of alopecia and grade 1 neuropathy) with at least 4 weeks elapsed since the last exposure to cytotoxic chemotherapy or to radiotherapy and at least 6 weeks elapsed since exposure to nitrosoureas or mitomycin c. 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. examples include but are not limited to partial gastrectomy, history of small intestine surgery, and celiac disease. * history of uncontrolled sleep apnea syndrome and other conditions that could result in excessive daytime sleepiness, such as severe chronic obstructive pulmonary disease. * difficulty swallowing capsules * inability to take nothing by mouth except for water and prescribed medications for 2 hours before and 1 hour after each dose of mln8237 * received more than 4 previous cytotoxic chemotherapeutic regimens including regimens used as adjuvant or neo-adjuvant therapies. there is no limit on the number of noncytotoxic therapies (eg, hormonal and immunologic) that participants may have received. tyrosine kinase inhibitors (eg, tarceva and iressa®) are considered noncytotoxic compounds. * prior treatment with high-dose chemotherapy, defined as chemotherapy requiring the use of peripheral blood or bone marrow stem cell support for hematopoietic reconstitution * prior treatment with radiation therapy involving ≥25% of the hematopoietically active bone marrow * clinical and/or radiographic evidence of cerebral metastases. however, participants who have a history of central nervous system (cns) metastasis but who have no radiographic or clinical evidence of residual tumor (eg, following complete surgical resection or stereotactic radiosurgery) are not excluded from participation in this study * absolute neutrophil count \<1500/mm\^3; platelet count \<100,000/mm\^3 * serum creatinine \>1.6 mg/dl or a measured or estimated creatinine clearance \<40 ml/minute * bilirubin \>1.5 times the upper limit of the normal range (uln); aspartate aminotransferase (ast)/alanine aminotransferase (alt) \>2.5 times the uln, and alkaline phosphatase (alp) \>2.5 times the uln. both the ast and alp may be elevated up to 5 times the uln if their elevation can be reasonably ascribed to the presence of metastatic disease to liver and/or to bone; however, the alt must in all circumstances be \<2.5 times the uln * abnormalities on 12-lead electrocardiogram (ecg) considered by the investigator to be clinically significant or baseline prolongation of the rate-corrected qt interval (eg, repeated demonstration of qtc interval \> 450 milliseconds) * left ventricular ejection fraction (lvef) \< 50% * known or suspected human immunodeficiency virus (hiv) positive or hepatitis b surface antigen-positive status, or known or suspected active hepatitis c infection. testing for these agents is not required in the absence of clinical findings or suspicion. * less than 4 weeks between the last dose of an investigational agent and the first dose of mln8237 * admission or evidence of benzodiazepine dependence or abuse and/or alcohol abuse or an inability to restrict consumption of alcohol to no more than 1 standard unit of alcohol per day during the study and for 30 days from the last dose of study treatment. a standard unit of alcohol is defined as one 12-oz (150ml) beer, 1.5 oz (45ml) of 80-proof alcohol, or one 6-oz (175ml) glass of wine. * lactose intolerant, for the food effect cohort only.
