Study Overview

Efficacy and Safety of BEZ235 Compared to Everolimus in Patients With Advanced Pancreatic Neuroendocrine Tumors

This was a multicenter, open label, randomized phase II study to evaluate the efficacy and safety of BEZ235 as compared to everolimus in patients with advanced, low to intermediate grade pancreatic neuroendocrine tumor (pNET).

Patients with advanced (unresectable or metastatic), low to intermediate grade (histologically confirmed well and moderately differentiated) pancreatic neuroendocrine tumor (pNET) were randomized to either BEZ235 or everolimus. The study was planned to include 140 patients, with 70 patients in the BEZ235 treatment group and 70 patients in the everolimus treatment group. An interim analysis was conducted on 62 randomized patients. The study was terminated as the BEZ235 treatment did not demonstrate a progression free survival advantage to everolimus treatment.

Arms and Interventions

Participant Group/ArmIntervention/Treatment
EXPERIMENTAL: BEZ235

DRUG: BEZ235

  • BEZ235 400 mg bid p.o. (by mouth, twice daily)

Primary Outcome MeasuresMeasure DescriptionTime Frame
Progression Free Survival (PFS)PFS is defined as the time from the date of randomization until the date of the first radiologically documented disease progression or death due to any cause. PFS is based on local investigator assessment. Patients will be followed up for the duration of the study and for an expected average of every 12 weeks after randomization. Progression is defined using Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0), as a 20% increase in the sum of the longest diameter of all target lesions, or unequivocal progression of non-target lesions, or the appearance of new lesions.up to approx. 18 months
Secondary Outcome MeasuresMeasure DescriptionTime Frame
Objective Response RateProportion of patients with a best overall response during the study of complete response (CR) or partial response (PR), based on the investigator assessment. 2. Per Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0) for all target and non-target lesions, as well as new lesions as assessed by CT or MRI: Complete Response (CR), Disappearance of all target and non-target lesions; Partial Response (PR), >=30% decrease in the sum of the longest diameter of all target lesions; Overall Response (OR) = CR + PR.up to approx. 18 months
Overall Survival (OS)Time from randomization to the date of death due to any causeup to approx. 30 months
Time to Treatment Failure (TTF)Time from randomization to the date of the first of the following events:death due to any cause or progressive disease, treatment discontinuation due to toxicity or treatment discontinuation due to patient preferenceup to approx. 18 months
