A Study of BBI608 in Combination With Standard Chemotherapies in Adult Patients With Pancreatic Cancer

Study Overview
=================
Brief Summary
-----------------
This is an open label, multi-center, multi-arm, dose-escalation study of BBI608 administered in combination with Gemcitabine and nab-Paclitaxel, mFOLFIRINOX, FOLFIRI, or MM-398 with 5-FU and leucovorin.

Detailed Description
-----------------
This is an open label, multi-center, multi-arm, dose-escalation study of BBI608 administered in combination with either Gemcitabine and nab-Paclitaxel, mFOLFIRINOX, FOLFIRI, or MM-398 with 5-FU and leucovorin. A study cycle will consist of daily and continuous oral administration of BBI608 for four weeks (28 days) in combination with Gemcitabine and nab-Paclitaxel, mFOLFIRINOX, FOLFIRI, or MM-398 with 5-FU and leucovorin. Combination treatment will continue in 28 day cycles until disease progression, unacceptable toxicity or another discontinuation criterion is met. BBI608 may be continued post-progression if the patient is obtaining potential clinical benefit, in the opinion of the investigator. If administration of Gemcitabine and/or nab-Paclitaxel, mFOLFIRINOX, FOLFIRI, or MM-398 with 5-FU and leucovorin is discontinued due to chemotherapy backbone-related toxicities, the administration of BBI608 can be continued.

Patients enrolling onto Arm A (Gemcitabine and nab-Paclitaxel) or Arm B (mFOLFIRINOX) are allowed to have up to two prior lines of systemic therapy, with adjuvant therapy counted as one line of therapy as long as disease recurrence occurred > 6 months of last dose of therapy. Prior systemic therapy in the metastatic setting is allowed for as long as the therapy contained BBI608 in combination with either Gemcitabine and nab-Paclitaxel or mFOLFIRINOX. Toxicities related to prior therapy must have completely resolved (except for alopecia and anemia), or be deemed irreversible. Patients who received Gemcitabine-based therapy in an adjuvant setting will be allowed to be enrolled on Arm A of the trial (Gemcitabine with nab-Paclitaxel) as long as their last Gemcitabine administration was at least 6 months prior to the first dose of BBI608. Patients enrolling onto Arm A (Gemcitabine with nab-Paclitaxel) are allowed to have prior mFOLFIRINOX in combination with BBI608 in the metastatic setting. Patients enrolling onto Arm B (mFOLFIRINOX) are allowed to have prior Gemcitabine with nab-Paclitaxel in combination with BBI608 in the metastatic setting. Prior treatment with radiotherapy is allowed. Patients enrolling onto Arm C (FOLFIRI) or Arm D (MM-398 with 5-FU and leucovorin) must have failed one prior line of gemcitabine-based therapy with or without BBI608 in the metastatic setting. No additional lines of therapy in the metastatic setting are allowed. Prior adjuvant therapy with gemcitabine is allowed as long as disease recurrence occurred > 6 months of last dose of therapy. Toxicities related to prior therapy must have completely resolved (except for alopecia and anemia), or be deemed irreversible. Prior treatment with radiotherapy is allowed. ≥ 18 years of age.
