A Phase I/Expansion Study of Dasatinib

Stopped early · Phase 1

Conditions studied: Refractory Solid Tumors, Pancreatic Adenocarcinoma

In brief

The purpose of this study is to find the highest dose of the drugs gemcitabine and dasatinib that can be given for the treatment of pancreatic cancer. Gemcitabine (also called Gemzar™)is a drug that is given intravenously. Dasatinib (also called Sprycel™) is a tablet and will be taken by mouth. Gemcitabine is approved by the Food and Drug Administration (FDA) for the treatment of advanced breast, lung and pancreatic cancer. Dasatinib is approved by the FDA for the treatment of chronic myeloid leukemia (CML), acute lymphoblastic leukemia or for patients that are resistant to imatinib mesylate (Gleevec™ ). This study will try to find the highest doses of these drugs that can be tolerated when taken in combination. The study will also look at how the drugs work in the body, and will see if there is any effect on pancreatic cancer.

You may qualify if…

• Eligibility Criteria Specific for Dose Escalation Phase
• Patients must have histologically confirmed solid tumor malignancy that is metastatic or unresectable and for which standard therapy would include gemcitabine or for which standard curative or palliative measures do not exist or are no longer effective.
• Patients must not have had radiation therapy, hormonal therapy, biologic therapy or chemotherapy for cancer within the 28 days prior to study day 1.
• Eligibly Criteria Specific for Expansion Phase at Recommended Phase II Dose

• Prior gemcitabine only allowed if the gemcitabine was administered in the adjuvant setting and > 6 months has elapsed between diagnosis of metastatic disease and last gemcitabine treatment.
• No history for other carcinomas within the last five years, except cured non-melanoma skin cancer, curatively treated in-situ cervical cancer, or localized prostate cancer with a current PSA of <1.0 mg/dL on 2 successive evaluations, at least 3 months apart, with the most recent evaluation no more than 4 weeks prior to day 1 of the study drug treatment. .
