The drug being tested in this study is called MLN0264. MLN0264 is being tested to treat tumors in people who have metastatic adenocarcinoma of the pancreas expressing guanylyl cyclase C (GCC). This study will assess tumor size reduction in patients who are administered MLN0264.~The study will enroll 42 to 81 patients. All participants will be administered MLN0264 at 1.8 mg/kg as a single, 30-minute, intravenous (IV) infusion on Day 1 of each 3-week treatment cycle, followed by a rest period of 20 days. Participants will continue to receive MLN0264 for up to 1 year or until disease progression or unacceptable toxicity occurs.~This multi-centre trial will be conducted worldwide. The overall time to participate in this study is approximately 19 months. Participants will make 3 to 6 visits to the clinic per treatment cycle, an end-of-treatment visit will occur 30 days after the last dose of study medication, and follow-up assessments will occur every 12 weeks until death or 6 months after the last patient completes treatment - whichever occurs first.
The purpose of this study is to assess the efficacy, safety and tolerability of MLN0264 in patients with advanced or metastatic guanylyl cyclase C (GCC)-positive adenocarcinoma of the pancreas.
