Stage III Pancreatic Cancer AJCC v8, Stage IV Pancreatic Cancer AJCC v8, Unresectable Pancreatic Carcinoma
Conditions
Brief summary
This phase I trial studies the side effects and best dose of bosentan and how well it works when given together with gemcitabine and nab-paclitaxel for the treatment of pancreatic cancer that cannot be removed by surgery (unresectable). Bosentan may block the hormone endothelin and prevent the growth and spread of pancreatic cancer. Drugs used in chemotherapy, such as gemcitabine and nab-paclitaxel, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving bosentan with chemotherapy (gemcitabine and nab-paclitaxel) may work better in treating patients with pancreatic cancer compared to chemotherapy alone.
Detailed description
PRIMARY OBJECTIVE: I. To assess the safety, toxicity and feasibility of administering bosentan with nab-paclitaxel and gemcitabine. SECONDARY OBJECTIVES: I. To assess the response rate associated with this combination therapy in first line pancreatic cancer patients. II. To assess the progression-free survival and overall survival of all patients who start protocol therapy, and describe the outcomes based on measures of compliance during the lead-in week, and compliance with supplement during chemotherapy. EXPLORATORY OBJECTIVES: I. To determine the impact of bosentan on the mass transport in the tumor (surrogate of alterations in tumor stroma and blood flow). (Pharmacodynamic Investigations) II. To describe the pharmacokinetic profile of nab-paclitaxel and bosentan and compare to historic single-agent profile. (Pharmacokinetic Investigations) III. To explore the association between hepatotoxicity to study agents and organic anion-transporting polypeptide (OATP) polymorphisms. (Pharmacogenomic Investigations) IV. To explore biomarkers on pre-treatment biopsy samples and peripheral blood samples for correlations of predictive of response. V. To describe quality of life utilizing the Functional Assessment of Cancer Therapy: General (FACT-G) questionnaire. OUTLINE: Patients receive bosentan orally (PO) twice daily (BID) on days -7 to 21 or 8-21 of cycle 1 and days 1-21 of subsequent cycles. Patients also receive nab-paclitaxel intravenously (IV) over 30 minutes and gemcitabine IV over 30 minutes on days 1, 8, and 15. Cycles repeat every 21 days in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up at 30 days. Patients who complete study treatment without disease progression are followed up every 2 months until disease progression and then biannually thereafter. Patients who complete study treatment with disease progression are followed up biannually.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Incidence of adverse events | Up to 30 days after last dose of protocol therapy | Will be recorded using the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version (v) 4.0. |
| Dose limiting toxicities (DLTs) | Up to 21 days (Cycle 1) | Toxicities will be graded according to NCI CTCAE v 4.0. DLT's apply only to bosentan-only single stage AND cycle 1 and should be attributable to the treatment. |
| Compliance | During the first week | Number of bosentan tablets and bottles returned will be reconciled with the patient diary. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Progression-free survival (PFS) | Time to disease progression/ relapse or death as a result of any cause, assessed up to 2 years | Will be evaluated using the Kaplan-Meier methods, both as a single group and by disease classification (metastatic versus \[vs.\] advanced unresectable). Response will also be examined by disease classification as part of a secondary analysis. |
| Overall survival (OS) | Time to death as a result of any cause, assessed up to 2 years | Will be evaluated using the Kaplan-Meier methods, both as a single group and by disease classification (metastatic vs. advanced unresectable). Response will also be examined by disease classification as part of a secondary analysis. |
| Time to treatment failure (TTF) | Time to treatment termination for any reason (progression, toxicity, death, patient preference), assessed up to 2 years | Will be evaluated using the Kaplan-Meier methods, both as a single group and by disease classification (metastatic vs. advanced unresectable). Response will also be examined by disease classification as part of a secondary analysis. |
