Trial Outcomes & Findings for Gemcitabine, Oxaliplatin and Panitumumab in Kras/B-raf Wild-Type Biliary Track and Gallbladder Cancer (NCT NCT01308840)

NCT ID: NCT01308840

Last Updated: 2016-08-17

Results Overview

Tumor measurement - same imaging modality used in pre-treatment evaluation - include radiological examination of all areas with affected disease. For pretreatment and at the end of cycle 2 CT scans (chest/abdomen/pelvis) will be used. For all subsequent cycles, CT of chest/abdomen/pelvis will be used every 8 weeks.

SECONDARY outcome

Timeframe: time to cancer progression or death

Progression-free survival was defined as the time from study enrollment to date of cancer progression or death, whichever occurred first. Progression was assessed using CT scans and the Response Evaluation Criteria In Solid Tumors criteria. Progression 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.

SECONDARY outcome

Timeframe: baseline to study completion

Any adverse event continuing after the study completion and considered potentially related to study treatment will be followed until resolution, stabilization or initiation of treatment that confounds the ability to assess the event
