Primary Outcome Measures
NameTimeMethod
Kaplan-Meier Estimate of Overall Survival: Intention to Treat (ITT) Population36 Months

Duration of OS was defined as the time from the date of randomisation to the date of death due to any cause. Subjects were followed until their date of death, loss to follow-up, withdrawal of consent for further follow-up for survival, or final database closure. OS was determined using the ITT population which included all subjects randomized into 1 of the 2 treatment arms. Subjects who were lost-to-follow-up or were not known to have died were censored at last date they were shown to be alive. Subjects who did not have any follow-up since the date of randomization were censored at the date of randomization.

Secondary Outcome Measures
NameTimeMethod
Kaplan-Meier Estimate of Progression-Free Survival (PFS): ITT PopulationUp to 38 months.

PFS was defined as the time from the date of randomization to the earliest date of disease progression (assessed by the investigator according to RECIST version 1.1) or death due to any cause. PFS was determined using the ITT population which included all subjects randomized into 1 of the 2 treatment arms. For subjects whose disease did not progress or who did not die, the PFS time was censored at the time of the last tumor assessment that demonstrated lack of disease progression. For subjects who received new anti-cancer therapy, the PFS time was censored at the start of the new anti-cancer therapy.

Clinical Benefit Rate (CBR): ITT PopulationUp to 38 months.

CBR was defined as the proportion of subjects with a CR, PR, or stable disease (SD) for at least 6 months (≥ 182 days).

Duration of Response (DOR): Efficacy Evaluable PopulationUp to 38 months.

DOR was defined as the time from first documented CR or PR until the earliest evidence of disease progression or death from any cause. Subjects who were alive without documented disease progression per RECIST version 1.1 were censored at the date of last tumor assessment without disease progression or start of new anti-cancer therapy for the study disease.

Incidence of Dose Reductions: Safety PopulationUp to 38 months.

Proportion of subjects who had a reduction in dose.

Quality of Life Questionnaire-Core 30 (QLQ-C30) Individual Scale, Overall Score: ITT PopulationUp to 39 months

The QLQ-C30 is composed of 5 multi-item functional scales (physical, role, social, emotional and cognitive functioning), a global health status/QoL scale, 3 symptom scales (fatigue, nausea/vomiting, and pain), and 6 single items (financial impact, appetite loss, diarrhoea, constipation, insomnia and dyspnoea). Most items are scaled 1 to 4 (1 = not at all, 2 = a little, 3 = quite a bit, 4 = very much) except the items contributing to the global health status/QoL, which are 7-point questions (1 = very poor to 7 = excellent). Raw scores were transformed using a linear transformation to standardize the results so that scores range from 0 to 100. n=number of subjects who completed each individual scale. Note that for scores measuring function, a higher score represented a higher "better" level of functioning, while for scores measuring symptoms, a higher score represented a lower "worse" level of symptoms.

QLQ-C30 Individual Scale, Change Over Time: ITT PopulationFrom Baseline to Week 8, Week 16, Week 24, Week 32, Week 40, Week 48, Week 56.

The QLQ-C30 is composed of 5 multi-item functional scales (physical, role, social, emotional and cognitive functioning), a global health status/QoL scale, 3 symptom scales (fatigue, nausea/vomiting, and pain), and 6 single items (financial impact, appetite loss, diarrhea, constipation, insomnia and dyspnea). Most items are scaled 1 to 4 (1 = not at all, 2 = a little, 3 = quite a bit, 4 = very much) except the items contributing to the global health status/QoL, which are 7-point questions (from 1 = very poor to 7 = excellent). Raw scores were transformed using a linear transformation to standardize the results so that scores range from 0 to 100. n=number of subjects who completed each individual scale. Note that for scores measuring function, a higher score represented a higher "better" level of functioning, while for scores measuring symptoms, a higher score represented a lower "worse" level of symptoms.

Quality of Life Questionnaire-breast Cancer-specific Module (BR23) Score Value: ITT PopulationBaseline

The QLQ-BR23 incorporates 5 multi-item scales to assess systemic therapy side effects, arm symptoms, breast symptoms, body image and sexual functioning, and 3 single items to assess sexual enjoyment, upset by hair loss and future perspective. Most items were scaled one to four except the items contributing to the global health status/QoL, which were seven-point questions. Raw scores were transformed using a linear transformation to standardize the results so that scores ranged from 0-100. Note that for scores measuring function, a higher score represented a higher "better" level of functioning, while for scores measuring symptoms, a higher score represented a lower "worse" level of symptoms.

BR23 Score Change Over Time: ITT PopulationUp to 38 months.

The QLQ-BR23 incorporates 5 multi-item scales to assess systemic therapy side effects, arm symptoms, breast symptoms, body image and sexual functioning, and 3 single items assess sexual enjoyment, upset by hair loss and future perspective. Most items were scaled one to four except the items contributing to the global health status/QoL, which were seven-point questions. Raw scores were transformed using a linear transformation to standardize the results so that scores ranged from 0-100. Note that for scores measuring function, a higher score represented a higher "better" level of functioning, while for scores measuring symptoms, a higher score represented a lower "worse" level of symptoms.

Objective Response Rate (ORR): Efficacy Evaluable PopulationUp to 38 months.

ORR was defined as the proportion of subjects with a complete response (CR) or a partial response (PR), assessed by the investigator based on Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 The analyses were performed for subjects in the efficacy evaluable population who had measurable disease as determined by the investigator at baseline.

Population Mean ± Standard Deviation (SD) Area Under the Concentration-Time Curve (AUC) for NKTR-102 and Metabolites After Multiple Administration of 145 mg/m^2 NKTR-102 [25]Up to 38 months.

Plasma concentrations of NKTR-102 and its major metabolites irinotecan, SN38, SN38G, and APC were measured using validated analytical methods. The population pharmacokinetic (PK) model-derived mean AUC values were computed by integration from t = 0 (start of first dose) to 21 days after the last dose. Integration was implemented using a separate compartment defined as the amount of drug or metabolite in the central compartment divided by the model-estimated volume of distribution.

Population Mean ± SD Maximum Plasma Concentration (Cmax) for NKTR-102 and Metabolites After Multiple Administration of 145 mg/m^2 NKTR-102 [26]Up to 38 months.

Plasma concentrations of NKTR-102 and its major metabolites irinotecan, SN38, SN38G, and APC were measured using validated analytical methods. The population PK model-derived mean Cmax values were computed by integration from t = 0 (start of first dose) to 21 days after the last dose. Integration was implemented using a separate compartment defined as the amount of drug or metabolite in the central compartment divided by the model-estimated volume of distribution.

Population Mean ± SD Elimination Half-life (t½) for NKTR-102 After Multiple Administration of 145 mg/m^2 NKTR-102 [27]Up to 38 months.

Plasma concentrations of NKTR-102 and its major metabolites irinotecan, SN38, SN38G, and APC were measured using validated analytical methods. The population PK model-derived mean t½ values were computed by integration from t = 0 (start of first dose) to 21 days after the last dose. Integration was implemented using a separate compartment defined as the amount of drug or metabolite in the central compartment divided by the model-estimated volume of distribution. The t½ of all analytes was primarily driven by NKTR-102. Thus, the NKTR-102 t½ of 37 days also applies to all NKTR-102 metabolites.
