4P-12-1 A Randomized Phase II Trial of Dasatinib plus Abiraterone Compared to Abiraterone Alone for Metastatic, Castration-Resistant Prostate Cancer Prior to Chemotherapy
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.
Combined Exercise Program for Early Breast Cancer Survivors
PRIMARY OBJECTIVES:
I. To determine whether a 16-week exercise intervention will improve components of
metastasis (MetS) in breast cancer survivors soon after completion of cancer-related
treatments by measuring changes in body composition, waist circumference, blood pressure,
and serum levels of insulin, glucose, lipids, C-reactive protein, and hemoglobin A1c
(HbA1c).
II. To determine whether a 16-week exercise intervention will improve physical fitness in
breast cancer survivors soon after completion of cancer-related treatments by measuring
cardiorespiratory fitness and muscle strength.
III. To assesses the feasibility of a supervised exercise intervention in early breast
cancer survivors.
IV. To determine whether a 16-week exercise intervention will result in a reduction in
adipose tissue inflammation in obese breast cancer survivors soon after completion of
cancer-related treatments by measuring ATM phenotype and ATM cytokine expression.
V. To determine whether breast cancer survivors can maintain positive benefits of an
exercise intervention following a 12-week follow-up period by measuring changes in body
composition, waist circumference, blood pressure, and serum levels of insulin, glucose,
lipids, C-reactive protein, and HbA1c, cardiorespiratory fitness and muscle strength.
OUTLINE:
Patients are randomized to 1 of 2 arms.
Arm I (Control): Patients refrain from increasing physical activity levels for 16 weeks.
Arm II (Exercise): Patients participate in supervised exercise sessions over 60 minutes
thrice weekly and are encouraged to participate in a home-based exercise session over 30-45
minutes once weekly for 16 weeks.
