BEZ235 Phase II Trial in Patients With Advanced Pancreatic Neuroendocrine Tumors (pNET) After Failure of mTOR Inhibitor Therapy.

Brief Summary
This is a Phase II study in 2 stages, evaluating BEZ235 plus best supportive care (BSC) versus placebo plus BSC in patients with advanced pancreatic neuroendocrine tumors (pNET) after failure of mTOR inhibitor therapy.

Study design: This was a Phase II, two-stage, multicenter study, where Stage 1 was a single arm, open label design and Stage 2 was planned to be a randomized, double-blind study.

However, at the end of Stage 1, the futility was met and hence the Stage 2 was not initiated.

Eligibility Criteria
Inclusion Criteria:

* Unresectable or metastatic, histologically confirmed low or intermediate grade pancreatic neuroendocrine tumor with radiological evidence of disease progression since last treatment
* Refractory disease to treatment with mTOR inhibitor
* Measurable disease per RECIST Version 1.1 using Computed Tomography (CT) or Magnetic Resonance Imaging (MRI)
* Prior or concurrent therapy with SSA is permitted; a stable dose at least 2 months prior to study start and must continue on the stable dose while receiving study treatment; SSA is not considered as a systemic treatment.
* WHO PS ≤ 1
* Adequate bone marrow function or organ function

Exclusion Criteria:

* Previous treatment with any PI3K or AKT inhibitor
* Discontinuation prior mTOR inhibitor therapy due to toxicity
* Poorly differentiated neuroendocrine carcinoma, high-grade neuroendocrine carcinoma, adenocarcinoid, goblet cell carcinoid and small cell carcinoma
* Radiotherapy, or major surgery within 4 weeks prior to study treatment start
* Hepatic artery embolization or cryoablation/ radiofrequency ablation of hepatic metastasis within 2 months of study treatment start.
* More than 3 prior systemic treatment regimens (including cytotoxic chemotherapy, targeted therapy, immunotherapy)

Official Title
A Multicenter, Two Stage, Phase II Study, Evaluating the Efficacy of Oral BEZ235 Plus Best Supportive Care (BSC) Versus Placebo Plus BSC in the Treatment of Patients With Advanced Pancreatic Neuroendocrine Tumors (pNET) After Failure of mTOR Inhibitor Therapy.
Primary Outcomes
Outcome Description
PFS rate at 16 weeks was defined as a binary variable. Patients were considered as 'progression free' after 16 weeks if they had an overall lesion response of complete response (CR) partial response ('PR) or stable disease (SD)' and "progressed" if they had an overall lesion response of 'Progressive disease (PD) at the scan which occurred on day 105 after start of treatment, or later. Patients whose 16 weeks tumor assessment was unknown, missing or outside the window was not considered as 'progression free' and was considered a "failure" and counted only in the denominator for the estimation of the 16 week progression free rate.
Outcome Measure
Stage 1 - Progression Free Survival (PFS) Rate Analysis at 16 Weeks as Per Local Radiology Review
Outcome Time Frame
16 weeks after the first BEZ235 administration.

Secondary Outcomes
Outcome Description
Overall Response rate was defined as the proportion of patients with a best overall response of complete response or partial response, based on investigator's assessment as per RECIST criteria version 1.1. Based on futility analysis conducted at the end of stage 1, stage 2 was not initiated.
Outcome Time Frame
Baseline, every 8 weeks up to 31 months
Outcome Measure
Stage 1- Overall Response Rate (ORR)
Outcome Description
Disease control rate was defined as the proportion of patients with a best overall response of Complete Response, Partial response, or Stable disease, based on the investigator's assessment per RECIST version 1.1. Based on futility analysis conducted at the end of stage 1, stage 2 was not initiated.
