Phase 2, Nab Paclitaxel/Gemcitabine Alone and in Combination With ACP-196 in Subjects With Metastatic Pancreatic Cancer

A Phase 2, Randomized, Proof-of-Concept Study of Nab-Paclitaxel/Gemcitabine Alone and in Combination With ACP-196 in Subjects With Previously Untreated Metastatic Pancreatic Cancer

To evaluate the safety and efficacy of ACP-196 and nab paclitaxel/gemcitabine in subjects with previously untreated metastatic pancreatic cancer using standard response criteria

A Phase 2, multicenter, open-label, randomized clinical trial. The study was to evaluate the efficacy and safety of ACP-196 plus nab-paclitaxel/gemcitabine compared with nab-paclitaxel/gemcitabine in subjects who have previously untreated metastatic pancreatic cancer.

Inclusion Criteria:

• Men and women ≥ 18 years of age.
• ECOG performance status of 0 or 1.
• Histologically or cytologically confirmed metastatic adenocarcinoma of the pancreas.
• No previous radiotherapy, chemotherapy or investigational therapy for the treatment of metastatic disease. Prior treatment with 5-FU or gemcitabine administered as a radiation sensitizer in the adjuvant setting is allowed, provided at least 6 months have elapsed since completion of the last dose and no lingering toxicities are present.

Exclusion Criteria:

• Prior malignancy (other than pancreatic cancer), except for adequately treated basal cell or squamous cell skin cancer, in situ cervical cancer, or other cancer from which the subject has been disease free for ≥ 2 years or which will not limit survival to < 2 years.
• Known central nervous system (CNS) metastases and/or carcinomatous meningitis.
• Significant cardiovascular disease such as uncontrolled or symptomatic arrhythmias, congestive heart failure, or myocardial infarction within 6 months of screening
• Malabsorption syndrome, disease significantly affecting gastrointestinal function, or resection of the stomach or small bowel, symptomatic inflammatory bowel disease, partial or complete bowel obstruction, or gastric restrictions and bariatric surgery, such as gastric bypass.
• Biliary obstruction or presence of a percutaneous biliary drain. Note: Subjects with endobiliary stents may participate as long the enrollment criterion relating to serum bilirubin concentration is met.
• Breastfeeding or pregnant
