Cabozantinib S-malate in Treating Patients With Relapsed Osteosarcoma or Ewing Sarcoma

A Phase 2 Study of XL184 (Cabozantinib) in Treating Patients With Relapsed Osteosarcomas and Ewing Sarcomas

This phase II trial studies how well cabozantinib s-malate works in treating patients with osteosarcoma or Ewing sarcoma that has grown or returned (come back) after a period of improvement. Cabozantinib s-malate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and may also prevent the growth of new blood vessels that tumors need to grow.

Study Overview

• Conditions: Recurrent Ewing Sarcoma; Recurrent Osteosarcoma; Stage III Osteosarcoma AJCC v7; Stage IV Osteosarcoma AJCC v7; Stage IVA Osteosarcoma AJCC v7; Stage IVB Osteosarcoma AJCC v7; Metastatic Osteosarcoma; Metastatic Ewing Sarcoma; Unresectable Ewing Sarcoma; Unresectable Osteosarcoma
• Intervention / Treatment: Other: Laboratory Biomarker Analysis; Drug: Cabozantinib S-malate

Detailed Description

PRIMARY OBJECTIVES:

I. To evaluate the antitumor activity of cabozantinib s-malate (cabozantinib) for Ewing sarcomas, in terms of 6-month objectives response as per the Response Evaluation Criteria in Solid Tumors, Revised (RECIST version [v]1.1).

II. To evaluate the antitumor activity of cabozantinib for osteosarcoma, in terms of 6-month objective response (complete response, partial response) and 6-month non-progression (complete response, partial response and stable disease), as per RECIST v1.1.

SECONDARY OBJECTIVES:

I. 6-month objective response. (Ewing sarcoma only) II. Best overall response (as per the revised RECIST v1.1). (Ewing sarcoma and osteosarcoma) III. 1- and 2-year progression-free survival. (Ewing sarcoma and osteosarcoma) IV. 1- and 2-year overall survival. (Ewing sarcoma and osteosarcoma) V. Cabozantinib safety. (Ewing sarcoma and osteosarcoma) VI. To assess the ability of metabolic tumor response as measured by fludeoxyglucose (FDG)-positron emission tomography (PET) at the end of one cycle of treatment to predict progression-free survival (PFS). (Ewing sarcoma and osteosarcoma) VII. Translational research: to determine and compare tumor expression of MET, phosphorylated (phosphor)-MET and circulating levels of HGF, soluble MET (sMET), VEGF-A, and soluble VEGF receptor 2 (VEGFR2) (sVEGFR2) prior to and following administration of cabozantinib. (Ewing sarcoma and osteosarcoma)

OUTLINE:

Patients receive cabozantinib s-malate orally (PO) once daily (QD) on days 1-28. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up every 6 months.

• Female subjects of childbearing potential must not be pregnant at screening; females of childbearing potential are defined as premenopausal females capable of becoming pregnant (ie, females who have had any evidence of menses in the past 12 months, with the exception of those who had prior hysterectomy); however, women who have been amenorrheic for 12 or more months are still considered to be of childbearing potential if the amenorrhea is possibly due to prior chemotherapy, antiestrogens, low body weight, ovarian suppression or other reasons

• The effects of Cabozantinib on the developing human fetus are unknown; for this reason and because tyrosine kinase inhibitors agents as well as other therapeutic agents used in this trial are known to be teratogenic, women of child-bearing potential and men must agree to use adequate contraception (see below) prior to study entry and for the duration of study participation; should a woman become pregnant or suspect she is pregnant while she is participating in this study, she should inform her treating physician immediately; men treated or enrolled on this protocol must also agree to use adequate contraception prior to the study, for the duration of study participation, and 4 months after completion of cabozantinib administration

  • Sexually active subjects (men and women) must agree to use medically accepted barrier methods of contraception (e.g., male or female condom) during the course of the study and for 4 months after the last dose of study drug(s), even if oral contraceptives are also used; all subjects of reproductive potential must agree to use both a barrier method and a second method of birth control during the course of the study and for 4 months after the last dose of study drug(s)
• Metastatic or unresectable locally advanced
• Documented disease progression (as per RECIST v1.1) before study entry; for patients with osteosarcoma, this progression will be confirmed by central review on the basis of two CT scan or magnetic resonance imaging (MRI) obtained at less than 6 months in the period of 12 months prior to inclusion

• The subject is unable to swallow tablets
• The subject has a corrected QT interval calculated by the Fridericia formula (QTcF) > 500 ms within 28 days before treatment; note: if initial QTcF is found to be > 500 ms, two additional electrocardiograms (EKGs) separated by at least 3 minutes should be performed; if the average of these three consecutive results for QTcF is =< 500 ms, the subject meets eligibility in this regard

• The subject has had evidence within 2 years of the start of study treatment of another malignancy which required systemic treatment

• Pregnant women are excluded from this study because cabozantinib is a tyrosine kinase inhibitor with the potential for teratogenic or abortifacient effects; because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with cabozantinib, breastfeeding should be discontinued if the mother is treated with cabozantinib; these potential risks may also apply to other agents used in this study
• Human immunodeficiency virus (HIV)-positive patients on combination antiretroviral therapy are ineligible because of the potential for pharmacokinetic interactions with cabozantinib; in addition, these patients are at increased risk of lethal infections when treated with marrow-suppressive therapy; appropriate studies will be undertaken in patients receiving combination antiretroviral therapy when indicated
• Participation to a study involving a medical or therapeutic intervention in the last 30 days
• Prior participation in this study

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Best Overall Response	Will be analyzed independently for each stratum (osteosarcoma and Ewing sarcoma). Will be described using frequency, percentage, and 95% confidence interval (binomial law).	From the start of the treatment until disease progression/recurrence, assessed up to 2 years
Progression Free Survival (PFS)	Will be analyzed independently for each stratum (osteosarcoma and Ewing sarcoma). PFS will be analyzed using the Kaplan-Meier method. The median survival rates will be reported with a 95% confidence interval. Median follow-up will be calculated using the reverse Kaplan-Meier method. Multivariate analyses can also be carried out based on Cox's proportional risk method and after checking the risk proportionality hypothesis.	Time from start of treatment to time of progression or death, whichever occurs first, assessed up to 2 years
Overall Survival (OS)	Will be analyzed independently for each stratum (osteosarcoma and Ewing sarcoma). OS will be analyzed using the Kaplan-Meier method. The median survival rates will be reported with a 95% confidence interval. Median follow-up will be calculated using the reverse Kaplan-Meier method. Multivariate analyses can also be carried out based on Cox's proportional risk method and after checking the risk proportionality hypothesis.	Time from start of treatment to the time of death, assessed up to 2 years
Incidence of Adverse Events	Will be assessed using the Common Terminology Criteria for Adverse Events (CTCAE) version 4. Quantitative variables will be described using mean and standard errors if the normality assumption is satisfied, else other descriptive statistics (median, range, quartiles) will be used. Qualitative variables will be described using frequency, percentage, and 95% confidence interval.	Up to 2 years
Non-progression at 6 Months - Ewing Sarcoma	Non-progression defined as complete response (CR), partial response (PR), or stable disease (SD) as per the Response Evaluation Criteria In Solid Tumors Criteria, revised RECIST v1.1. As per revised RECIST v1.1, progression is defined as at least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study, or a measurable increase in a non-target lesion, or the appearance of one or more new lesions.	At 6 months
