What is being measured
The primary outcome is the main question the study is designed to answer.
Primary: Objective Response Rate (ORR) by Response Evaluation Criteria in Solid Tumors (RECIST): Primary Efficacy Population
The ORR was defined as the proportion of patients with a complete response (CR) or a partial response (PR) per RECIST 1.0 based upon the best response as assessed by the Investigator. CR was defined by RECIST 1.1 as disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have had reduction in short axis to <10 mm. PR was defined by RECIST 1.1 as at least a 30% decrease in the sum of the diameters (SOD) of target lesions, taking as reference the baseline SOD. The analysis was performed for patients in the Primary Efficacy Population.
Measured: Every 6 weeks (± 5 days) from Cycle 1, Day 1 until documented disease progression, start of new therapy for cancer, death, or end of study (approximately 3 years and 11 months)
Secondary outcomes (27)
Secondary: Best Overall Response by Gynecologic Cancer Intergroup (GCIG) Criteria: MITT Population
Best overall response was defined as the proportion of patients with a CR or a PR as assessed per GCIG criteria. The GCIG proposed the following definition for the date of progression which used both the RECIST and cancer antigen 125 (CA-125) criteria. "A response according to CA-125 has occurred if there is ≥ 50% reduction in CA-125 levels from a pretreatment sample. The response had to be confirmed and maintained for at least 28 days. Patients can be evaluated according to CA-125 only if they had a pretreatment sample that was at least twice the upper limit of normal (ULN) and within 2 weeks prior to starting treatment." Analysis was performed in MITT Population.
Measured: Every 6 weeks (± 5 days) from Cycle 1, Day 1 until documented disease progression, start of new therapy for cancer, death, or end of study (approximately 3 years and 11 months)
Secondary: Best Overall Response by GCIG Criteria: Primary Efficacy Population

Secondary: Best Overall Response by GCIG Criteria: Platinum-Refractory Population
Best overall response was defined as the proportion of patients with a CR or a PR per assessed per GCIG criteria. The GCIG proposed the following definition for the date of progression which used both the RECIST and CA-125 criteria. "A response according to CA-125 has occurred if there is ≥ 50% reduction in CA-125 levels from a pretreatment sample. The response had to be confirmed and maintained for at least 28 days. Patients can be evaluated according to CA-125 only if they had a pretreatment sample that was at least twice the ULN and within 2 weeks prior to starting treatment."

Secondary: Best Overall Response by GCIG Criteria: Prior PLD Therapy Population
Best overall response was defined as the proportion of patients with a CR or a PR per assessed per GCIG criteria. The GCIG proposed the following definition for the date of progression which used both the RECIST and CA-125 criteria. "A response according to CA-125 has occurred if there is ≥ 50% reduction in CA-125 levels from a pretreatment sample. The response had to be confirmed and maintained for at least 28 days. Patients can be evaluated according to CA-125 only if they had a pretreatment sample that was at least twice the ULN and within 2 weeks prior to starting treatment." Analysis was performed in Prior PLD Therapy Population.
Measured: Every 6 weeks (± 5 days) from Cycle 1, Day 1 until documented disease progression, start of new therapy for cancer, death, or end of study (approximately 3 years and 11 months)
Secondary: Kaplan-Meier Estimate of Progression-Free Survival (PFS): MITT Population
According to enhanced RECIST 1.1, progressive disease was the appearance of one or more new lesions, OR an unambiguous increase in the sum of target lesion volumes with both 1) >20% increase in the sum of volumes (SOV) of all target lesions (taking as reference the nadir) and 2) greater than two times the variability of the measurements estimated by the sponsor and/or its designees.
Measured: Every 6 weeks (± 5 days) from Cycle 1, Day 1 until documented disease progression, start of new therapy for cancer, death, or end of study (approximately 3 years and 11 months)
Secondary: Kaplan-Meier Estimate of PFS: Primary Efficacy Population
PFS was defined as the time from the date of the first NKTR-102 administration to the date of PD or death due to any cause. Progressive disease was determined by Investigators using RECIST criteria. Patients who were alive without disease progression at the time of data-cut-off were censored at the time of the last tumor assessment that demonstrated a lack of disease progression (or on Cycle 1 Day 1 if the patient did not undergo repeated imaging while on study). Analysis was performed in Primary Efficacy Population.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
This is a multicenter, open-label, two-arm, 2-stage, Phase 2 study of NKTR-102 in patients with metastatic or locally advanced platinum-resistant ovarian cancer.
Approximately 70 patients will be randomized 1:1 into one of two treatment arms. NKTR-102 will be administered at a dose level of 145 mg/m^2 in both arms. In Arm A, NKTR-102 will be given on a q14d schedule. In Arm B, NKTR-102 will be given on a q21d schedule. After the initial 70 patients have been enrolled, Arm B will enroll approximately 110 additional patients.

Primary outcome
Primary: Objective Response Rate (ORR) by Response Evaluation Criteria in Solid Tumors (RECIST): Primary Efficacy Population
Time frame: Every 6 weeks (± 5 days) from Cycle 1, Day 1 until documented disease progression, start of new therapy for cancer, death, or end of study (approximately 3 years and 11 months)
The ORR was defined as the proportion of patients with a complete response (CR) or a partial response (PR) per RECIST 1.0 based upon the best response as assessed by the Investigator. CR was defined by RECIST 1.1 as disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have had reduction in short axis to <10 mm. PR was defined by RECIST 1.1 as at least a 30% decrease in the sum of the diameters (SOD) of target lesions, taking as reference the baseline SOD. The analysis was performed for patients in the Primary Efficacy Population.
