Sunitinib, Cyclophosphamide, and Methotrexate in Treating Patients With Metastatic Breast Cancer

December 18, 2019 updated by: University of California, San Francisco

Phase I/II Study of SU11248 (Sutent) in Combination With Metronomic Dosing of Cyclophosphamide and Methotrexate in Patients With Metastatic Breast Cancer

RATIONALE: Sunitinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as cyclophosphamide and methotrexate, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving sunitinib together with combination chemotherapy may kill more tumor cells.

PURPOSE: This phase I/II trial is studying the side effects and best dose of sunitinib when given together with cyclophosphamide and methotrexate to see how well they work in treating patients with metastatic breast cancer.

Detailed Description

OBJECTIVES:

Primary

  • To determine the maximum tolerated dose of the combination of metronomic dose cyclophosphamide and methotrexate with continuous dosing sunitinib malate. (Phase I)
  • To determine the time to disease progression in patients with metastatic breast cancer treated with metronomic dose chemotherapy with cyclophosphamide and methotrexate combined with continuous dosing of sunitinib malate. (Phase II)

Secondary

  • To determine the response rate in patients receiving this treatment.
  • To determine the duration of response in patients receiving this treatment.
  • To determine the toxicity of this regimen in these patients.
  • To determine the feasibility by assessment of toxicities of this regimen and number of voluntary withdrawals from the study.
  • To correlate outcome measures with possible surrogate markers including serial measurements of circulating tumor cells and circulating endothelial cells.

OUTLINE: This is a dose-escalation study of sunitinib malate.

  • Phase I: Patients receive oral sunitinib malate once daily. Beginning 14 days later, patients also receive oral cyclophosphamide once daily on days 1-21 and oral methotrexate twice daily on days 1, 2, 8, 9, 15, and 16. Treatment with sunitinib malate, cyclophosphamide, and methotrexate repeats every 21 days* in the absence of disease progression or unacceptable toxicity.
  • Phase II: Patients receive sunitinib malate at the maximum tolerated dose determined in phase I and cyclophosphamide and methotrexate as in phase I.

NOTE: *Course 1 includes 2 weeks of sunitinib malate alone followed by sunitinib malate, cyclophosphamide, and methotrexate for 21 days

Blood samples are collected periodically for measurement of circulating tumor cells, circulating endothelial cells, and vascular endothelial growth factor (VEGF) levels.

After completion of study treatment, patients are followed for 30 days and then every 2 months for 1 year.

Phase

Phase

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Maximum Tolerated Dose of Sunitinib (Phase I)
Time Frame: 8 weeks

Patients in each cohort were followed for DLT for at least 8 weeks (2 week lead-in with sunitinib and 6 weeks of treatment with sunitinib and metronomic cyclophosphamide and methotrexate) before opening accrual to the next dose level. Dose limiting toxicity (DLT) defined as: 1) ≥ grade 3 anemia that does not resolve with appropriate growth factors afebrile grade 4 neutropenia that does not resolve with growth factor support after ≥ 7 days 2) grade 4 neutropenia associated with fever (1 reading of oral temperature > 38.5 degrees Celsius or 3 readings of oral temperature > 38.0 degrees Celsius in a 24 hour period) 3) ≥ grade 3 thrombocytopenia 4) ≥ grade 3 non-hematologic toxicities, except those that can be controlled to grade 2 or less with appropriate treatment.

5) Inability to resume treatment with any of the study medications within 14 days of stopping due to treatment related toxicity.
8 weeks
Patients With Progression-free Survival (PFS) Greater Than or Equal to 12 Weeks (Phase II)
Time Frame: up to 12 weeks after treatment start date
Progression defined as: 25% increase or an increase of 10 sq. cm (whichever is smaller) in the sum of products of measurable lesions over smallest sum observed (over baseline if no decrease), or appearance of any lesion which had disappeared, or clear worsening of any evaluable disease, or appearance of any new lesion/site, or failure to return for evaluation due to deteriorating condition (unless deterioration is clearly unrelated to this cancer).
up to 12 weeks after treatment start date

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Overall Response Rate
Time Frame: until disease progression, up to 13 months post treatment

Per Response Evaluation Criteria in Solid Tumors (RECIST): Complete Response (CR): Complete disappearance of all measurable and evaluable disease. No new lesions.

Partial Response (PR): greater than or equal to 50% decrease under baseline in the sum of the products of perpendicular diameters of all measurable lesions. No progression of evaluable disease. No new lesions.
