Oxaliplatin, Gemcitabine, and Erlotinib Study in Patients With Advanced Chemo-naïve Pancreatic Cancer

NCT ID: NCT00636883

Last Updated: 2014-01-22

Basic Information

• Recruitment Status: TERMINATED
• Clinical Phase: PHASE2
• Total Enrollment: 9 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2008-01-31
• Study Completion Date: 2012-07-31

Brief Summary

The purpose of this study is to determine if the combination of Gemcitabine, Oxaliplatin and Erlotinib in the treatment of patients with pancreatic cancer will provide increased clinical benefits and improvement in their quality of life.

Detailed Description

Treatment Plan GEMOX-Erlotinib consists of erlotinib 100 mg orally daily starting day 1, Gemcitabine 1000 mg/m2 in 10 mg/m2/min (100 minutes) infusion on day 1 followed on day 2 by oxaliplatin 100 mg/m2 in a 2-hour infusion. Treatment will be repeated every 2 weeks. Each two weeks is a cycle. Tumor response evaluation will be performed every 2 months. If tumor progress, patient will be off study, but if the disease is stable or PR, CR obtained will continue treatment for total of 12 cycles. If at end of 12 cycles response continues, will administer Gemox and erlotinib till achieve maximum response. Then start Erlotinib maintenance therapy.

Sample size: A total of 34 patients are needed assuming expected response is greater than 10% (about 27%) and a power = 80%. Fourteen patients will be treated in the first stage; if one patient achieved PR then additional twenty patients will be enrolled in the study for a total of 34 patients.

Statistical Methods: Response rate with 95% CI and median time to progression of disease will be calculated. Success will be declared if the lower limit of the 95% CI of the response rate is greater than 10%. The 95% CI of the response rate will be calculated using exact methods. Survival curve will be estimated using Kaplan-Meier Method. Descriptive statistics will be used to describe patient demographics, adverse events, serious adverse events and reasons for termination. Two approaches to the efficacy and safety analyses will be done; the ITT (intent-to-treat) for the efficacy analysis and safety. The ITT analysis consists of patients who received at least one dose of the study drug and at least one on-treatment measurement of the primary efficacy endpoint (overall response). The safety analysis consists of patients who received at least one dose of the study drug and at least one safety measurement done. A detailed description of the statistical methods, table and listing shells will be provided in the statistical analysis (SAP) before database lock or data transfer to the study biostatistician.
