A Study Of Regorafenib In Advanced Pancreatic Cancer Patients

Study Overview

A Study of Regorafenib in Advanced Pancreatic Cancer Patients

This study tests regorafenib as a single agent in the treatment of metastatic pancreatic cancer patients who have progressed after prior chemotherapy with gemcitabine. The prognosis for these patients is particularly grim, no other standard treatment options exist, and novel approaches are desperately needed.

This is a single arm, single stage Phase II study designed to evaluate progression free survival (PFS) in patients with metastatic pancreatic cancer who have failed at least one prior line of therapy and treatment with gemcitabine. This study is open at the Levine Cancer Institute (LCI). A total of 32 patients will be enrolled over a two years. Following informed consent and eligibility check, all patients will start oral regorafenib therapy (120 mg daily for 3 weeks on / 1 week off; 28 day cycle) with a built-in dose escalation to 160mg after the first cycle as tolerated, and will continue therapy until progression or patient withdrawal. Patients will undergo radiological staging after the first two cycles of regorafenib therapy. Patients with progressive disease will be removed from the study. Patients who have at least stable disease will continue regorafenib therapy, at the Investigator's discretion, and will be radiologically restaged bimonthly.

Primary Outcome Measures	Measure Description	Time Frame
Number of Patients Progression Free and Surviving at 16 Weeks as a Percent of All Enrolled Subjects	16-week progression free survival was determined for each subject as a binary variable indicating whether or not the subject is alive and progression free at 16 weeks after treatment start, with progression defined radiographically using RECIST v1.1 or clinically based upon investigator assessment.	16 weeks after enrollment

Secondary Outcome Measures	Measure Description	Time Frame
Progression Free Survival	PFS is defined as duration of time from enrollment to the study to time of progression or death. Disease progression (PD) can be objectively determined as per RECIST v1.1 (Response Evaluation Criteria in Solid Tumors, where PD is defined as a 20% increase in the sum of the longest diseased of target lesions, or a measurable increase in non-target lesion, or the appearance of new lesions) or progression can be subjective as determined by the investigator. Evidence for subjective progressions must be documented in medical records. For surviving subjects who do not have documented PD, PFS will be censored at last radiologic assessment. For subjects who receive subsequent anti-cancer therapy prior to documented PD, PFS will be censored at last radiologic assessment prior to commencement of subsequent therapy. Subjects who experience a PFS event following an interval equal to two or more scheduled CT assessments will be censored at date of last assessment prior to first missed assessment.	From date of treatment start to date of progression or death, or censored as described above; assessed for approximately 3 years.
Overall Survival	Overall survival is defined as the duration from enrollment date to the date of death from any cause. Subjects who are alive or lost to follow-up at the time of the analysis will be censored at the last known date they were alive.	From date of treatment start to date of death, or censored as described above; assessed for approximately 3 years.
Overall Response	Overall response will be determined as the best treatment response for each patient as a binary variable indicating whether or not the patient achieved a Complete Response (CR) or Partial Response (PR) as determined by RECIST v1.1 criteria. Per Response Evaluation Criteria in Solid Tumors Criteria (RECIST v1.1):Complete Response (CR) is the disappearance of all lesions (target and non target); Partial Response (PR) is at least 30% decrease in the sum of the diameters of target lesions from baseline and no new lesions or unequivocal progression in non target lesions from baseline; Stable Disease (SD) is neither sufficient shrinkage in target lesions to qualify for PR (less than 30% decrease) nor sufficient increase in target lesions (versus smallest sum of diameters) to qualify for PD (less than 20% increase), with no new lesions or unequivocal progression in non target lesions from baseline. For the purposes of response determination, confirmatory scan for CR and PR is not required.	From enrollment to best response while on regorafenib; Subjects remained on treatment until disease progression or death or discontinuation from study or at least 28 days after last dose (subjects were on treatment for an average of 6 weeks)
Disease Control	Disease control will be determined for each patient as a binary variable indicating whether or not the patient achieved a best overall best response of CR, PR, or stable disease as determined by RECIST v1.1 criteria. Per Response Evaluation Criteria in Solid Tumors Criteria (RECIST v 1.1): Complete Response (CR) is the disappearance of all lesions (target and non target); Partial Response (PR) is at least 30% decrease in the sum of the diameters of target lesions from baseline and no new lesions or unequivocal progression in non target lesions from baseline; Stable Disease (SD) is neither sufficient shrinkage in target lesions to qualify for PR (less than 30% decrease) nor sufficient increase in target lesions (versus smallest sum of diameters) to qualify for PD (less than 20% increase), with no new lesions or unequivocal progression in non target lesions from baseline.	From enrollment to best response while on regorafenib; Subjects remained on treatment until disease progression or death or discontinuation from study or at least 28 days after last dose (subjects were on treatment for an average of 6 weeks)
