- Bevacizumab inhibits blood vessel growth in cancer cells by blocking a growth factor called VEGF. Dasatinib inhibits the action of proteins called tyrosine kinases, which promote and stimulate blood vessel formation and cancer growth and spread.
- Using the two drugs in combination may provide a more effective cancer treatment than either drug used alone.
- Both drugs have been approved by the Food and Drug Administration for different cancer types, but their use in combination sis experimental.
- To determine the highest doses of the combination of dasatinib and bevacizumab that can be safely given to patients with different cancers and to find out what effects, good and bad, these drugs may have on the patient and the disease.
- Adult patients with an advanced solid tumor cancer that cannot be treated successfully with standard therapies.
- Patients in Group 1 receive dasatinib and bevacizumab together throughout the study. The dose is increased in successive groups of three to six patients until the optimum safe dose is determined. Patients take dasatinib by mouth once a day and receive bevacizumab as an infusion through a vein once every 2 weeks in 28-day treatment cycles.
- Patients in Group 2 are randomly assigned to receive either dasatinib or bevacizumab for cycle one, and then both drugs for all subsequent cycles. The drug doses are based on the optimum doses found in Group 1 patients.
- Patients have a physical examination and blood and urine tests every 2 weeks for cycles 1 and 2, and then every 4 weeks for the duration of treatment.
- Patients have CT or MRI scans or another imaging test such as ultrasound every 8 weeks to monitor the cancer s response to treatment.
- Tumor biopsies are obtained from patients in Group 2 before treatment, 2 weeks into the first treatment cycle, and 2 weeks into the second cycle.
- Dynamic, contrast-enhanced MRI (DCE-MRI) tests are done on patients in Group 2 before treatment, 2 weeks into the first cycle and 4 weeks into the second cycle. This MRI test uses a special non-radioactive dye that shows blood flow in a certain part of the body.

This determination will be made by a member of the interventional radiology team or surgical associate investigator and an associate investigator. This requirement is not necessary for patients in group 1. 3.1.4 Age greater than or equal to 18 years. Because no dosing or adverse event data are currently available on the use of dasatinib in combination with bevacizumab in patients less than 18 years of age, children are excluded from this study, but may be eligible for future pediatric phase 1 combination trials. 3.1.5 ECOG performance status 0 or 1.

Consideration should be given to using alternative medications not impacting CYP3A4 while on dasatinib therapy. Patients may not be receiving any prohibited potent CYP3A4 inhibitors. For these drugs, a wash-out period of greater than or equal to 7 days is required prior to starting dasatinib treatment. Category I drugs that are generally accepted to have a risk of causing Torsades de Pointes.

If a patient has a history of any type primary lung cancer and hemoptysis, they will be excluded. 3.2.14 History of high grade varices. 3.2.15 Use of herbal supplements are not permitted within 7 days of trial commencement and on study. Vitamin supplement (above a typical single multi-vitamin) usage is discouraged unless clearly indicated by an existing medical condition. An Associate or Principal Investigator will have the discretion regarding which vitamin supplements are permitted. 3.2.16 Known hypersensitivity to Chinese hamster ovary cell products or recombinant human antibodies. 3.2.17 Use of any other concurrent investigational agents for treatment or anticancer agents including hormonal therapy, except in the case of prostate cancer patients who are being treated with LHRH agonist at the time of trial entry 3.2.18 Pregnant women are excluded from this study because bevacizumab is an antibody to VEGF with the potential for teratogenic or abortifacient effects. Dasatinib is a potential teratogen. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother bevacizumab or dasatinib, breastfeeding should be discontinued if the mother is treated on this study.
|Official title||A Phase I Study of Dasatinib in Combination With Bevacizumab in Advanced Solid Tumors|
|Principal investigator||Christina M Annunziata, M.D.|
|Description||Background: Dasatinib is an inhibitor of SRC family kinases, BCR-ABL, c-KIT, EPHA2 and PDGF beta receptor. Bevacizumab is a humanized IgG1 monoclonal antibody (MAb) that binds all biologically active isoforms of human vascular endothelial growth factor (VEGF, or VEGF-A) with high affinity (k(d) equal to 1.1nM). This Phase I trial is open to patients with all solid tumors. Objectives: Determine the safety and toxicity of the combination of dasatinib and bevacizumab. Determine biochemical changes in the src-FAK and src-PLC-. and VEGF signal transduction pathways in tumor and stromal cells in response to treatment at the MTD, in a pilot fashion, if those changes are statistically significant. Eligibility: Adults with histologically documented solid tumor malignancy that is metastatic or unresectable and for which standard curative therapies do not exist or are no longer effective. Patients must be off prior chemotherapy, radiation therapy, hormonal therapy, or biological therapy for at least 4 weeks. All patients enrolling in Group 2 must have at least one lesion amenable to biopsy. ECOG performance status 0 or 1 and adequate organ and marrow function. Design: Group 1 will receive dasatinib and bevacizumab together at the start of study in a dose escalation fashion. Group 2 will be randomized as to which agent they receive for cycle one. Cycles 2 and beyond are treated using both agents. Tumor biopsies will be obtained from patients in Group 2 before treatment, two weeks into mono-therapy, and two weeks into combinatorial therapy. DCE-MRI studies will be obtained on patients in Group 2 before treatment, two weeks into monotherapy, four weeks into monotherapy, and two weeks into combinatorial therapy. Patients will be evaluated for toxicity in clinic every 2 weeks for Cycles 1 and 2, and then every 4 weeks. Patients will be evaluated for response every 8 weeks using the RECIST criteria. Approximately 48 patients will be needed to achieve the objectives of the trial.|
