Abiraterone Acetate and Prednisone With or Without Dasatinib in Treating Patients With Metastatic Hormone-Resistant Prostate Cancer
A Randomized Phase II Trial of Dasatinib Plus Abiraterone Compared to Abiraterone Alone for Metastatic, Castration-Resistant Prostate Cancer Prior to Chemotherapy
研究概览
详细说明
PRIMARY OBJECTIVES:
I. To compare the progression-free survival of men with metastatic castration-resistant prostate cancer treated with abiraterone (abiraterone acetate) plus dasatinib to that of men treated with abiraterone alone.
SECONDARY OBJECTIVES:
I. To describe the toxicity profile of the combination, as well as the rate of prostate-specific antigen (PSA) response, objective responses, and changes in circulating tumor cell (CTC) numbers.
OUTLINE: Patients are randomized to 1 of 2 treatment arms. ARM A: Patients receive abiraterone acetate 1000 mg orally (PO) once daily (QD) and prednisone 5 mg PO twice daily (BID) on days 1-28. Courses repeat every 4 weeks in the absence of disease progression or unacceptable toxicity.
ARM B: Patients receive abiraterone acetate and prednisone as patients in arm A. Patients also receive dasatinib 100 mg PO QD on days 1-28. Courses repeat every 4 weeks in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up periodically.

描述
Inclusion Criteria:
Metastatic, castration-resistant prostate cancer
- Defined as evaluable radiographic disease with rising PSA x 2 (at least 1 week apart) or radiographic progression (new soft tissue/bone lesions or enlarging soft tissue lesions) despite medical or surgical castration
- No limit on prior hormonal therapies (i.e. anti-androgens, ketoconazole) except that subject must not have received abiraterone previously
- No limit on prior biologic therapies (i.e. immune therapy, antiangiogenic, targeted) except that patient should not have received dasatinib or other v-src sarcoma (Schmidt-Ruppin A-2) viral oncogene homolog (avian) (src)-targeted therapy
No prior chemotherapy for metastatic disease
* Subjects who have received chemotherapy in the neoadjuvant or adjuvant setting will be eligible provided chemotherapy was completed > 6 months prior to enrollment
- Eastern Cooperative Oncology Group (ECOG) 0-2
- Total bilirubin =< 1.5 times the institutional upper limit of normal (ULN) except for Gilbert's syndrome
- Hepatic enzymes (aspartate aminotransferase [AST], alanine aminotransferase [ALT] ) =< 2.5 times the institutional ULN
- Serum sodium (Na), potassium (K+), magnesium (Mg+), phosphate and calcium (Ca+) > lower limit of normal (LLN)
- Serum creatinine =< 1.5 time the institutional ULN
- Hemoglobin (Hb) >= 9
- Platelets >= 100,000
- Absolute neutrophil count (ANC) >= 1000
- Ability to take oral medication (study medications must be swallowed whole)
- Men with fathering potential must agree to use contraception throughout study treatment; acceptable methods include: condoms, sponge, intrauterine device (IUD), oral contraceptives
- Concomitant medications * Patient agrees to discontinue St. Johns wort while receiving dasatinib therapy (discontinue St. Johns wort at least 5 days before starting dasatinib)
Exclusion Criteria:
Known hepatitis B or C or human immunodeficiency virus (HIV), regardless of viral load
* Testing for the purposes of enrollment is not mandatory, however a documented history of these infections will be exclusionary due to concerns for drug-drug interactions with antivirals and potential for increased risk of liver toxicity
- Radiation for palliation of bony metastases within the preceding 2 weeks
Prior chemotherapy for metastatic castration-resistant prostate cancer (CRPC)
* Immune therapy with sipuleucel-T is allowed, provided the last infusion was >= 28 days prior to study therapy and there has been at least one documented PSA value rising after completion of sipuleucel-T therapy or progression of disease on imaging after sipuleucel-T
Malignancy (aside from prostate cancer) which required radiotherapy or systemic treatment within the past 5 years
- Superficial bladder cancer treated with intravesical therapy and currently in remission will not be an exclusion
- Skin cancers will not be an exclusion, except for melanoma with a thickness > 1 mm
Concurrent medical condition which may increase the risk of toxicity, including:
- Pleural or pericardial effusion of any grade at the time of study entry
Cardiac symptoms; any of the following should be considered for exclusion: ** Uncontrolled angina, congestive heart failure or myocardial infarction (MI) within (6 months)
- Diagnosed congenital long QT syndrome
- Any history of clinically significant ventricular arrhythmias (such as ventricular tachycardia, ventricular fibrillation, or Torsades de pointes) ** Prolonged QTc/f interval on pre-entry electrocardiogram (> 450 msec)
- Hypokalemia or hypomagnesemia if it cannot be corrected prior to abiraterone administration
History of significant bleeding disorder unrelated to cancer, including:
- Diagnosed congenital bleeding disorders (e.g., von Willebrand's disease)
- Diagnosed acquired bleeding disorder within one year (e.g., acquired anti-factor VIII antibodies)
- Ongoing or recent (=< 3 months) significant gastrointestinal bleeding
Prohibited treatments and/or therapies
- Should not be on any additional anti-cancer therapy except for luteinizing hormone-releasing hormone (LHRH) agonist/antagonist; specifically excluded medications include ketoconazole, estrogens, and anti-androgens
Category I drugs that are generally accepted to have a risk of causing Torsades de pointes including: (Patients must discontinue drug 7 days prior to starting dasatinib)
- Quinidine, procainamide, disopyramide
- Amiodarone, sotalol, ibutilide, dofetilide
- Erythromycin, clarithromycin
- Chlorpromazine, haloperidol, mesoridazine, thioridazine, pimozide
- Cisapride, bepridil, droperidol, methadone, arsenic, chloroquine, domperidone, halofantrine, levomethadyl, pentamidine, sparfloxacin, lidoflazine
- Prisoners or subjects who are involuntarily incarcerated
- Subjects who are compulsorily detained for treatment of either a psychiatric or physical (eg, infectious disease) illness

Progression-free survival (PFS)
大体时间:From the start of abiraterone acetate until first evidence of disease progression or until death from any cause, whichever occurs first, assessed up to 3 years
|
PFS defined by Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1.
A one-sided, 0.05-level log rank test will be used to compare the two arms in terms of PFS.
PFS will be estimated using the product-limit method of Kaplan and Meier.
