|Pancreatic Cancer||Drug: Capecitabine Drug: Docetaxel Drug: Gemcitabine||Phase 1|
|Study Design:||Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
|Official Title:||A Dose Escalating (Phase I) Study Looking at the Biomodulation of Capecitabine by Docetaxel and Gemcitabine in Patients With Advanced Pancreas Cancer|
- Maximum Tolerated Dose (MTD) [ Time Frame: Weekly up to 24 weeks ]MTD will be the dose at which 1 or fewer patients (≤ 1/6) experiences a DLT during the first or second cycle with the next higher dose having at least 2/3 or 2/6 patients experiencing Dose Limiting Toxicities (DLT).
- Common Toxicities [ Time Frame: Weekly up to 24 weeks ]The NCI Common Terminology Criteria for Adverse Events version 3.0 was used for adverse event reporting and toxicity grading.
- Therapeutic Response [ Time Frame: every 8 weeks, up to 24 weeks ]Per Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0) for target lesions and assessed by MRI: Complete Response (CR), Disappearance of all target lesions; Partial Response (PR), >=30% decrease in the sum of the longest diameter of target lesions; Overall Response (OR) = CR + PR.

Experimental: capecitabine, docetaxel, gemcitabine
Dose escalation study of mGTX using three dose levels (DL1-3). Patients received docetaxel on days 1 and 8, gemcitabine on days 8 and 15, and capcitabine on days 8 through 21. Gemcitabine fixed dose at 750 mg/m2 over 75 min, capecitabine twice daily and escalated from 500 to 650 mg/m2 at DL2 and docetaxel increased from 30 to 36 mg/m2 at DL3.
Will be give on days 8-21
Other Name: XelodaDrug: Docetaxel
Will be given on days 1 and 8,
Other Name: TaxotereDrug: Gemcitabine
A fixed dose rate will be give on days 8 and 15.
Other Name: Gemzar
Rationale: Single agent gemcitabine is considered standard care for patients with advanced pancreatic cancer. However, better treatments offering improved outcomes are needed for people with this disease. The combination of docetaxel and capecitabine has shown significant and broad clinical activity in a variety of tumors. Laboratory research on the combination of capecitabine, docetaxel, and gemcitabine indicates synergistic action against tumor cells. The current study will test this combination in patients. The drug administration schedule in this study is aimed at maximizing the potential of activation of capecitabine by both docetaxel and gemcitabine.
Treatment: Study participants will be given docetaxel, gemcitabine, and capecitabine. All study drugs will be administered through intravenous infusions in three week cycles. Docetaxel will be given on days 1 and 8, gemcitabine on days 8 and 15, and capecitabine on days 8 through 21. This schedule will be followed by 1 week of rest without administration of study drugs. Since the primary goal of this study is to identify the maximum tolerated dose of the study drugs in combination, patients who enroll in the beginning of the study will receive lower amounts of the study drugs compared to patients who enroll later in the study. Several tests and exams will be given throughout the study to closely monitor patients.
