NCT03875235 · STUDY IN CONTEXT

Durvalumab or Placebo in Combination With Gemcitabine/Cisplatin in Patients With 1st Line Advanced Biliary Tract Cancer (TOPAZ-1)

Draft scope assessment: narrower. Linked by condition-string match at the cancer-entity level. The study's eligibility - stage, biomarker, treatment line and prior therapy - has not been reconciled against this page's definition, so its population is narrower than this page in ways not yet recorded. The condition was transformed or resolved through the terminology hierarchy to reach this cancer type, so the link itself is a candidate a reviewer must confirm. Found because this study's registry identifier is printed in an FDA approval notice, an FDA product label or an NCI summary held by this site. The citing document and the exact position of the identifier inside it are recorded. Being cited is not a statement that the study supports this treatment.

Overall Survival (OS) was defined as the time from the date of randomization until death due to any cause. Any patient not known to have died at the time of analysis was censored based on the last recorded date on which the patient was known to be alive. Median OS was calculated using the Kaplan-Meier technique. The second interim analysis was pre-specified after approximately 397 OS events occurred in both arms (59% maturity).

secondary · POSTED

PFS based on investigator assessments according to RECIST version 1.1 was defined as time from date of randomization until date of objective disease progression or death (by any cause in the absence of progression), regardless of whether the patient withdrew from randomized therapy or received another anticancer therapy prior to progression. Progression (i.e., PD) was defined as at least a 20% increase in the sum of diameters of target lesions (TLs) and an absolute increase of ≥5mm, taking as reference the smallest sum of diameters since treatment started including the baseline sum of diameters, or a measurable increase in a non-target lesion, or the appearance of new lesions. Median PFS was calculated using the Kaplan-Meier technique.

    Adverse events: from first dose of study medication up to 90 days after the last dose of study medication or until the initiation of the first subsequent therapy (whichever comes first), up to maximum of approximately 67 months. All-cause mortality (death due to any cause): from randomization up to analysis DCO (28 February 2025). Maximum timeframe of approximately 67 months.
    event definition
    There were 341 patients randomized to Durvalumab + Gemcitabine + Cisplatin and 344 patients randomized to Placebo + Gemcitabine + Cisplatin (Full Analysis Set). Five of these patients did not receive treatment (resulting in 338 in Durvalumab arm and 342 in Placebo arm for Safety Analysis Set). Hence, the Total numbers at risk for all-cause mortality is 341 (Durvalumab) and 344 (Placebo), while the Total number at Risk by any Serious/Other Adverse Event is 338 (Durvalumab) and 342 (Placebo).
