Brief summary

This phase II trial studies the possible benefits of treatment with different combinations of the drugs durvalumab, olaparib and cediranib vs. the usual treatment in patients with ovarian, primary peritoneal, or fallopian tube cancer that has come back after a period of improvement with platinum therapy (recurrent platinum resistant). Usual treatment is the type of treatment most patients with this condition receive if they are not part of a clinical study. Combination therapies studied in this trial include MEDI4736 (durvalumab) plus olaparib and cediranib, durvalumab and cediranib, or olaparib and cediranib. Monoclonal antibodies, such as durvalumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumors cells to grow and spread. Olaparib is an inhibitor of PARP, an enzyme that helps repair deoxyribonucleic acid (DNA) when it becomes damaged. Blocking PARP may help keep cancer cells from repairing their damaged DNA, causing them to die. PARP inhibitors are a type of targeted therapy. Cediranib may stop the growth of tumor cells by blocking VEGF (an enzyme). needed for cell growth. Giving different combinations of durvalumab, olaparib and cediranib may work better in increasing the duration of time that the cancer does not progress compared to the usual treatment.

Median follow-up time was 4.8 months (Inter-Quartile Range: 2.0-7.9 months).The relationship of randomized treatment assignment to progression free survival. The RECIST 1.1 criteria are used for disease progression. 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).

MeasureTime frameDescription
Objective Response RateFrom the start of the treatment until disease progression/recurrence, or termination by the DMC. The median followup time was 4.3 months. The maximum followup time was 11 months. Patients are no longer being assessed.Determination of response should take into consideration all target and non-target lesions. Here are the definitions of CR, PR, PD and SD: Complete Response (CR): Disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to \<10 mm. Partial Response (PR): At least a 30% decrease in the sum of the diameters of target lesions, taking as reference the baseline sum diameters. Progressive Disease (PD): 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. Stable Disease (SD): Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as reference the smallest sum diameters (i.e. the nadir) while on study. The CI is the Jeffreys interval.
Duration of ResponseThroughout study treatment, up to 10.6 months.Tumor response was assessed using Response Evaluation Criteria In Solid Tumors Criteria (RECIST 1.1) criteria. Duration of response was defined as the time from the first documentation of objective tumor response (complete response (CR) or partial response (PR)) to the first documented progressive disease (PD), or to death due to any cause, whichever occurs first. Per RECIST, Complete Response (CR) is defined as the disappearance of all target lesions; Partial Response (PR) is defined as an \>=30% decrease in the sum of the longest diameter of target lesions; Progressive Disease (PD) is defined as a 20% increase in the sum of the longest diameter of target lesions, or a measurable increase in a non-target lesion, or the appearance of new lesions.

Duration of response was defined as the time from the first documentation of objective tumor response (complete response (CR) or partial response (PR)) to the first documented progressive disease (PD), or to death due to any cause, whichever occurs first. Per RECIST, Complete Response (CR) is defined as the disappearance of all target lesions; Partial Response (PR) is defined as an \>=30% decrease in the sum of the longest diameter of target lesions; Progressive Disease (PD) is defined as a 20% increase in the sum of the longest diameter of target lesions, or a measurable increase in a non-target lesion, or the appearance of new lesions. Reporting the number of months from complete or partial response until disease progression, death or censoring, whichever occurs first. In the absence of disease progression or death, censoring time is based on date of last CT scan.

Time frame: Throughout study treatment, up to 10.6 months.

Population: Patients with Complete or Partial Response

Objective Response Rate

Determination of response should take into consideration all target and non-target lesions. Here are the definitions of CR, PR, PD and SD: Complete Response (CR): Disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to \<10 mm. Partial Response (PR): At least a 30% decrease in the sum of the diameters of target lesions, taking as reference the baseline sum diameters. Progressive Disease (PD): 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. Stable Disease (SD): Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as reference the smallest sum diameters (i.e. the nadir) while on study. The CI is the Jeffreys interval.

Time frame: From the start of the treatment until disease progression/recurrence, or termination by the DMC. The median followup time was 4.3 months. The maximum followup time was 11 months. Patients are no longer being assessed.

Population: Patients with measurable disease, a baseline tumor assessment, and at least one on-treatment tumor assessment. The study was terminated for futility of all the experimental arms. Many patients withdrew from treatment prior to their first on-treatment tumor assessment.

Overall Survival

Overall survival will be presented by Kaplan Meier methods. Overall Survival (OS) is defined as the duration of time from study entry to date of death from any cause. A subject who has not died will be censored on the date that they were last known to be alive.

Time frame: Time from study entry to date of death from any cause, or termination by the DMC. The median followup time was 4.3 months. The maximum followup time was 11 months. Patients are no longer being assessed.
