简要总结
This randomized phase II/III trial studies how well cediranib maleate and olaparib work when given together or separately, and compares them to standard chemotherapy in treating patients with ovarian, fallopian tube, or primary peritoneal cancer that has returned (recurrent) after receiving chemotherapy with drugs that contain platinum (platinum-resistant) or continued to grow while being treated with platinum-based chemotherapy drugs (platinum-refractory). Cediranib maleate and olaparib may stop the growth of tumor cells by blocking enzymes needed for cell growth. Chemotherapy drugs work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. It is not yet known whether giving cediranib maleate and olaparib together may cause more damage to cancer cells when compared to either drug alone or standard chemotherapy.
详细描述
PRIMARY OBJECTIVES:
I. To assess the efficacy and identify (in)active arm(s) of the combination of cediranib maleate (cediranib) and olaparib, cediranib alone, olaparib alone, and physician's choice standard of care chemotherapy, as measured by progression-free survival (PFS) in the setting of recurrent platinum-resistant or-refractory ovarian, primary peritoneal or fallopian tube cancer. (Phase II) II. To assess the efficacy of the combination of cediranib and olaparib, and cediranib monotherapy, as measured by overall survival (OS) and PFS, as compared to physician's choice standard of care chemotherapy in women with recurrent platinum-resistant or-refractory ovarian, primary peritoneal or fallopian tube cancer. (Phase III)
SECONDARY OBJECTIVES:
I. To assess the efficacy of the combination of cediranib and olaparib, cediranib alone, olaparib alone, and physician's choice standard of care chemotherapy, as measured by objective response rate (ORR: partial or complete response) by Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 criteria, in the setting of recurrent platinum-resistant or-refractory ovarian, primary peritoneal or fallopian tube cancer. (Phase II) II. To assess safety endpoints, as measured by frequency and severity of adverse events by Common Terminology Criteria for Adverse Events (CTCAE). (Phase II and Phase III) III. To assess the efficacy of the combination of cediranib and olaparib, and cediranib monotherapy, as measured by ORR as compared to physician's choice standard of care chemotherapy in the setting of recurrent platinum-resistant or-refractory ovarian, primary peritoneal or fallopian tube cancer. (Phase III)

结局指标
主要结局
Progression-free Survival (PFS) (Phase II Only)
时间窗: The protocol required lesion assessments every 9 weeks from cycle 1, day 1 for the first year, then every 12 weeks thereafter until disease progression. Approximately 42 months.
Progression free survival (PFS) was defined as the number of months between study enrollment and documentation of disease progression (RECIST 1.1) or death from any cause. Patients still alive and disease free at the last follow-up were censored on the date of last CT Scan, or the CT Scan date prior to two missed assessments. Disease progression is defined as at least a 20% increase in the sum of the diameters of target lesions, taking as reference the smallest sum on study (this includes the baseline sum if that is the smallest on study). In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm. (Note: the appearance of one or more new lesions is also considered progression).
