Prostate Cancer Clinical Trial
Use of an Experimental Drug, CC-115, With Enzalutamide in Men With Castration-Resistant Prostate Cancer
The main purpose of this study to define the good and/or bad effects of the combination of enzalutamide and CC-115 in patients with castration-resistant prostate cancer.

Radionuclide bone scan: at least 2 new bone lesions, as defined by the Prostate Cancer Clinical Trials Working Group 2 (PCWG2) criteria33
Serum testosterone < 50 ng/dL. Patients must continue primary androgen deprivation with an LHRH analogue (agonist or antagonist) if they have not undergone orchiectomy

Prior exposure to abiraterone acetate, ketoconazole or other specific CYP-17 inhibitors
Prior exposure to agents specifically targeting both mTOR complexes (dual TORC1+TORC2 inhibitors) and/or PI3K/AKT pathways

Unstable angina pectoris
Myocardial infarction ≤ 3 months prior to registration
Other clinically significant heart disease such as congestive heart failure requiring treatment or uncontrolled hypertension
Uncontrolled diabetes mellitus
Other concurrent severe and/or uncontrolled concomitant medical conditions (e.g., active or uncontrolled infection) that could cause unacceptable safety risks or compromise compliance with the protocol
Major surgery ≤ 2 weeks prior to registration or who have not recovered from side effects of such therapy. Subjects must have recovered from any effects of recent radiotherapy that might confound the safety evaluation of study drug.
Hematopoietic stem cell transplant ≤ 3 months prior to registration.
Adults of reproductive potential not employing two forms of birth control:
Males having partners who are female with child-bearing potential must agree that they and/or their partners will use at least two effective contraceptive methods (including one barrier method) when engaging in reproductive sexual activity throughout the study from the time of informed consent, and will avoid conceiving for 28 days after the last dose of CC-115.
Known human immunodeficiency virus (HIV) infection
Known chronic hepatitis B or C virus (HBV/HCV) infection
Concurrent active second malignancy for which the subject is receiving therapy, other than non-melanomatous skin cancer or superficial transitional cell carcinoma.
History of seizure or any condition that may predispose to seizure including, but not limited to, underlying brain injury, stroke in the past 6 months, primary brain tumors, brain metastases
Active treatment with medications that lower the seizure threshold which cannot be held:
Atypical antipsychotics (e.g., clozapine, olanzapine, risperidone, ziprasidone);
Phenothiazine antipsychotics (e.g., chlorpromazine, mesoridazine, thioridazine);
