Prostate Cancer Clinical Trials

MLN8237 for Metastatic Castrate Resistant and Neuroendocrine Prostate Cancer
A Phase II Trial of the Aurora Kinase A Inhibitor MLN8237 in Patients With Metastatic Castrate Resistant and Neuroendocrine Prostate Cancer
Status Conditions Phase Study ID
Closed Small Cell Prostate Cancer
Neuroendocrine Prostate Cancer
Phase II NCT01799278
Summary

This study will evaluate the response rate of MLN8237 in patients with histologically confirmed or clinically suspected metastatic neuroendocrine prostate cancer (NEPC). MLN8237 is an orally administered Aurora kinase A inhibitor that has demonstrated broad antitumor activity in vitro and in vivo. In preclinical models, aurora kinase inhibition resulted in dramatic and preferential anti-tumor activity in NEPC with suppression of neuroendocrine marker expression.

Eligibility Criteria (must meet the following to participate in this study)
  • Metastatic prostate carcinoma and at least one of the following:

    • Histologic diagnosis of small cell or neuroendocrine prostate cancer
    • Histologic diagnosis of prostate adenocarcinoma plus > 50% immunohistochemical staining for neuroendocrine markers (chromogranin, synaptophysin or neuron specific enolase)
    • Development of liver metastases in the absence of PSA progression as defined by PCWG2
  • Serum chromogranin A level >5 x upper limit of normal and/or serum neuron specific enolase (NSE) >2x upper limit of normal
  • Measurable disease by RECIST 1.1 with PCWG2 modifications
  • Patients with pure small cell neuroendocrine carcinoma on histology are not required to have received prior androgen deprivation therapy (ADT) or castrate levels of testosterone, but their testosterone state should be maintained for the duration of the study. Other patients are required to have surgical or ongoing chemical castration, with baseline testosterone level <50ng/dL.
  • Patients capable of fathering children must agree to use an effective method of contraception for the duration of the trial and should continue use for 4 months after last dose of study drug
  • Subjects must be able to take oral medication and to maintain a fast as required for 2 hours before and 1 hour after MLN8237 administration.
  • ANC > 1500/mm³, platelets > 100,000/mm³, Hgb > 9 g/dL. Values must be obtained without need for myeloid growth factor or platelet transfusion support within 14 days, however, erythrocyte growth factor is allowed as per published ASCO guidelines.
  • Total bilirubin ≤ ULN, SGOT (AST) and SGPT (ALT)< 1.5 x ULN. AST and/or ALT may be up to 5X ULN if with known liver metastases provided bilirubin is normal.
  • Adequate renal function as defined by serum creatinine ≤ 1.5 x ULN. If creatinine >1.5 x ULN, calculated or measured creatinine clearance must be ≥ 40 mL/minute (Cockcroft-Gault).
  • ECOG performance status 0-2
  • Estimated life expectancy > 3 months
  • Voluntary written informed consent before performance of any study-related procedure not part of normal medical care, with the understanding that consent may be withdrawn by the subject at any time without prejudice to future medical care.
Exclusions (conditions that would prevent participation in this study)
  • Radiation therapy to 25% of bone marrow within 2 weeks of first dose
  • Residual > Grade 2 toxicity from prior treatment must have resolved with the exception of those explicitly described elsewhere in entry criteria
  • Known history of uncontrolled sleep apnea syndrome and other conditions that could result in excessive daytime sleepiness, such as severe chronic obstructive pulmonary disease; requirement for supplemental oxygen.
  • Requirement for constant administration of proton pump inhibitor, H2 antagonist, or pancreatic enzymes. Intermittent uses of antacids or H2 antagonists are allowed (see section 5.5)
  • Severe or uncontrolled systemic infection
  • Myocardial infarction within 6 months prior to enrollment or has New York Heart Association (NYHA) Class III or IV heart failure, uncontrolled angina, severe uncontrolled ventricular arrhythmias, or electrocardiographic evidence of acute ischemia or active conduction system abnormalities. Prior to study entry, any ECG abnormality at Screening has to be documented by the investigator as not medically relevant.
  • Patient has received other investigational drugs with 14 days before enrollment
  • Serious medical or psychiatric illness likely to interfere with participation in this clinical study.
  • Other severe acute or chronic medical or psychiatric condition, including uncontrolled diabetes, malabsorption, resection of the pancreas or upper small bowel, requirement for pancreatic enzymes, any condition that would modify small bowel absorption of oral medications, or laboratory abnormality that may increase the risk associated with study participation or investigational product administration or may interfere with the interpretation of study results and, in the judgment of the investigator, would make the patient inappropriate for enrollment in this study.
  • Currently active other malignancy excluding controlled non-melanoma skin cancer. Patients are considered NOT to have "currently active" malignancy if they have completed any necessary therapy and are considered by their physician to be at less than 30% risk of relapse.
  • Treatment with the enzyme-inducing antiepileptic drugs phenytoin, carbamazepine or phenobarbital, or rifampin, rifabutin, rifapentine or St. John's wort within 14 days prior to the first dose of MLN8237 and during the study
  • Known history of human immunodeficiency virus (HIV) infection, hepatitis B, or hepatitis C. Testing is not required in the absence of clinical findings or suspicion.
