Summary:

      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.

          -  Relapsed disease after standard chemotherapy

          -  Patients must have measurable disease (lesion in previously irradiated field could be
             considered as measurable if progressive at inclusion) defined as per RECIST v1.1 with
             at least one lesion that can be measured in at least one dimension (longest diameter
             to be recorded) as >= 10 mm with spiral computed tomography (CT) scan

          -  Eastern Cooperative Oncology Group (ECOG) performance status =< 1

          -  Life expectancy of greater than 3 months

          -  Absolute neutrophil count >= 1,500/mcL

          -  Lymphocyte count > 1,000/mcL

          -  Platelets >= 100,000/mcL

          -  Total bilirubin =< 1.5 x upper limit of normal (ULN)

          -  Aspartate aminotransferase (AST) (serum glutamic oxaloacetic transaminase
             [SGOT])/alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase [SGPT])
             =< 3.0 x institutional upper limit of normal

          -  Creatinine =< 1.5 x ULN OR creatinine clearance >= 50 mL/min/1.73 m^2 for patients
             with creatinine levels above institutional normal (Cockcroft formula)

          -  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

               -  it is important to regularly consult a frequently-updated list; medical reference
                  texts such as the Physicians' Desk Reference may also provide this information;
                  as part of the enrollment/informed consent procedures, the patient will be
                  counseled on the risk of interactions with other agents, and what to do if new
                  medications need to be prescribed or if the patient is considering a new
                  over-the-counter medicine or herbal product

          -  The subject has experienced any of the following:

               -  Clinically-significant gastrointestinal bleeding within 6 months before the first
                  dose of study treatment

               -  Hemoptysis of >= 0.5 teaspoon (2.5 mL) of red blood within 3 months before the

                         -  Major surgery within 12 weeks before the first dose of study treatment;
                            complete wound healing from major surgery must have occurred 1 month
                            before the first dose of study treatment

                         -  Minor surgery (including uncomplicated tooth extractions) within 28
                            days before the first dose of study treatment with complete wound
                            healing at least 10 days before the first dose of study treatment;
                            subjects with clinically relevant ongoing complications from prior
                            surgery are not eligible

          -  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 is unable or unwilling to abide by the study protocol or cooperate fully
             with the investigator or designee

          -  The subject has had evidence within 2 years of the start of study treatment of another
             malignancy which required systemic treatment

          -  History of allergic reactions attributed to compounds of similar chemical or biologic
             composition to cabozantinib

          -  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
