Registered outcomes4

Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.

ListOutcomeTime frameDescription
PrimaryProgression-free Survival (PFS)36 months
Will be assessed per Response Evaluation Criteria in Solid Tumors 1.1 determined by retrospective independent central review. Will be compared between treatment arms using the stratified log rank test at one-sided level 0.025. The stratification factors will be used for the analysis. The hazard ratio (HR) for PFS will be estimated using a stratified Cox proportional hazards model, and the 95% confidence interval (CI) for the HR will be provided. Results from an unstratified analysis will also be provided. Kaplan-Meier methodology will be used to estimate the median PFS for each treatment arm, and Kaplan-Meier curves will be produced. Brookmeyer Crowley methodology will be used to construct the 95% CI for the median PFS for each treatment arm.
SecondaryOverall Survival (OS)60 months
The analyses for OS will follow intent-to-treat (ITT) principle and will be conducted separately within each cohort (pancreatic neuroendocrine tumor \[NET\] and carcinoid tumor). The distribution of OS will be estimated using the method of Kaplan-Meier. The median OS, along with the 95% CI, will be estimated by the two treatment groups. Overall survival will be compared between treatment arms using the stratified log-rank test at a one-sided cumulative 2.5% level of significance. The stratified Cox regression will be used to estimate the HR of OS, along with the 95% CI. A hierarchical approach will be used to control for family-wise type-I error rate, therefore OS will be formally statistically tested only if the primary efficacy endpoint, PFS, is statistically significantly different between the two treatment groups.
Secondary
Number of Patients Experiencing Grade 3+ Adverse Events (AEs) Graded According to the Common Terminology Criteria for Adverse Events (CTCAE) and Patient-Reported Outcomes Version of the Common Terminology Criteria for Adverse Events (PRO-CTCAE)
60 months
For CTCAE data, the frequency tables will be reviewed to determine the patterns. The overall adverse event rates will be compared between treatment groups using Chi-square test (or Fisher's exact test if the data in contingency table is sparse). PRO-CTCAE data will, at minimum, be analyzed similarly to CTCAE data. The initial analysis of each PRO-CTCAE item will use all available scores in an analysis which mirrors the approach used for the CTCAE data. Supplemental analysis will use model-based multiple imputation incorporating baseline patient characteristics and physician-rated performance status. CTCAE data may be incorporated as auxiliary data into multiple imputation models for AEs which are captured by both PRO-CTCAE and CTCAE. Results from supplemental analysis will be descriptively compared to the results of the initial analysis to assess the robustness of results to missing data. Additional analyses of PRO-CTCAE data beyond those specified above may be undertaken.
SecondaryRadiographic Response Rate36 months
Will be defined as the proportion of patients in each arm whose best response is either complete response (CR) or partial response (PR). Radiographic response rate for both cohorts: the analyses for confirmed radiographic response rate will follow the ITT principle and will be conducted separately within each cohort (pancreatic NET and carcinoid tumor). The proportion of patients with either confirmed CR or confirmed PR as their best response will be estimated using point estimates and 95% confidence intervals. Radiographic response rate will be compared between treatment arms using the 2-sample z-test to compare sample proportion at a one-sided 2.5% level of significance.
