Study Details

Study Description

Brief Summary

Phase I Study of Bevacizumab and Sorafenib Combined with Low Dose Cyclophosphamide in Patients with Refractory Solid Tumors and Leukemia. Patients with solid tumors (including central nervous tumors) that are recurrent or refractory to standard therapy, or for whom standard therapy is not available. Once a maximum tolerated dose (MTD) has been established in patients with recurrent or refractory solid tumors, the tolerability of this dose will be tested in patients with refractory or recurrent leukemia and an expanded cohort of patients with refractory or recurrent solid tumors.

Detailed Description

Phase I Study of Bevacizumab and Sorafenib Combined with Low Dose Cyclophosphamide in Patients with Refractory Solid Tumors and Leukemia. Patients with solid tumors (including central nervous tumors) that are recurrent or refractory to standard therapy, or for whom standard therapy is not available. Once a maximum tolerated dose (MTD) has been established in patients with recurrent or refractory solid tumors, the tolerability of this dose will be tested in a maximum of 6 patients, in cohorts of 3, with refractory or recurrent leukemia and a maximum of 24 evaluable patients, in cohorts of 6, with refractory or recurrent solid tumors.

Approximately 21-24 patients with refractory solid tumors to define the maximum tolerated dose (MTD) and 6 patients with recurrent or refractory leukemia,12 patients with refractory or recurrent bone or soft tissue sarcomas and 12 patients with other refractory or recurrent solid tumors (including lymphomas) to test the tolerability of this MTD in patients with hematological malignancies. Bevacizumab will be administered intravenously at a starting dose of 5 mg/kg every 3 weeks with sorafenib by mouth every 12 hrs at a starting dose of 90 mg/m2 every 12 hours and cyclophosphamide by mouth daily at a dose of 50 mg/m2/day (dose level 1). A course of therapy will be considered to be of 21 days duration. Once a maximum tolerated dose of sorafenib (sMTD) in combination with bevacizumab and cyclophosphamide has been determined, 6 patients with recurrent or refractory leukemia will be then be evaluated at the solid tumor MTD to test the tolerability of this combination in patients with hematological malignancies.

Eligibility Criteria

Criteria

• Ages Eligible for Study: N/A to 21 Years
• Sexes Eligible for Study: All
• Accepts Healthy Volunteers: No

Inclusion Criteria:

NOTE: As of May 2013, enrollment of solid tumor participants was completed. Participants with a diagnosis of leukemia continue to be enrolled.

• Diagnosis: Solid tumors, including central nervous system tumors and lymphomas, that are recurrent or refractory to standard therapy or for which there is no standard therapy. Histologic verification of diagnosis is required.

• Age: < or = 21 years of age at the time of original diagnosis

• Life expectancy: at least 8 weeks

• Performance status: Karnofsky > or = 50 for > 10 years of age; Lansky > or = 50 for children < or = 10 years of age.

• Organ Function: Must have adequate organ and marrow function

• Prior Therapy: Patient must have fully recovered from the acute toxic effects of all prior therapy prior to enrolling on study.

• Must not have current or recent use of full-dose anticoagulants

• Must not have received medications known to inhibit platelet function or known to selectively inhibit cyclooxygenase-2 (COX-2) activity

• Bevacizumab and sorafenib should not be administered to pregnant women.

• Pregnancy tests must be obtained in girls who are > 10 years of age or post-menarchal.

• Males or females of reproductive potential may not participate unless they have agreed to use an effective contraceptive method.

• Breast feeding should be discontinued if a mother wishes to participate in this study.

• Patients with a documented, chronic non-healing wound, ulcer, or bone fracture or history of a major surgical procedure or significant traumatic injury within 28 days prior to beginning therapy should be excluded due to preclinical evidence supporting the potential for delayed wound healing.

Exclusion Criteria:

• Body surface area < 0.3 m2

• Presence of a known bleeding diathesis or coagulopathy

• Patients with evidence of intra-tumoral central nervous system hemorrhage. in current scans. Patients are required to have a head CT or MRI within 2 weeks prior to study enrollment.

• Patients with known hypersensitivity to other recombinant human antibodies

• Patients who have an uncontrolled infection

• Patients with recurrent or refractory leukemia will be excluded from the dose escalation component of the phase I trial.
