Study of Gemzar®, Taxotere®, and Xeloda® (GTX) in Patients With Metastatic Pancreatic Cancer (Stage IVB)

Phase II Study of a Biochemically Synergistic Regimen for Metastatic Pancreatic Cancer (Stage IVB) With Gemzar, Taxotere and Xeloda (GTX)

This study is designed to determine whether an investigational drug combination consisting of Gemzar®, Taxotere®, and Xeloda®, (called GTX) is safe and effective in treating advanced pancreatic cancer and to study and enhance the utility of PET scans in the evaluation of patients with pancreatic cancer.

This Phase II multicenter study is designed to determine the response rate to a biochemically synergistic regimen with Gemzar, Taxotere, and Xeloda in patients with Stage IVB metastatic pancreatic cancer. It will further determine the overall and one year survival rates, the diseasefree interval, and the toxicities for this regimen in patients with metastatic pancreatic cancer.

Inclusion Criteria:

• Histologically confirmed adenocarcinoma of pancreas metastatic to liver and/or lungs or peritoneal surface. (a.k.a. Stage IV B).

• No prior chemotherapy with Gemzar, Xeloda and Taxotere.

• Measurable disease: Any mass reproducibly measurable in two perpendicular diameters by x-ray, physical examination, CT or MRI scans.

• The following lesions conventionally are not considered measurable:

  • CNS lesions
  • Blastic or lytic bone lesions (which should be documented and followed)
  • Radiated lesions unless progression after RT is documented

• Ineligible for other high priority national or institutional studies

• Prior radiation and surgery allowed:

  • > 3 weeks since surgery
  • > 4 weeks since RT

• Non pregnant females who are not breast feeding with a negative serum or urine β-HCG test within 1 week of starting the study. Men and women of childbearing potential must be willing to consent to using effective contraception while on treatment and for a reasonable period thereafter.

• The patient has not had a prior malignancy in last 5 years other than curatively treated carcinoma in-situ of the cervix or non-melanoma skin cancer
• No serious medical or psychiatric illness preventing informed consent or intensive treatment (e.g., serious infection).
• Patients with brain metastases are excluded.
