Study of Pazopanib in the Treatment of Osteosarcoma Metastatic to the Lung


  • Study type

  • Study phase

  • Study IDs

  • Describes the nature of a clinical study. Types include:

    • Observational study — observes people and measures outcomes without affecting results.
    • Interventional study (clinical trial) — studies new tests, treatments, drugs, surgical procedures or devices.
    • Medical records research — uses historical information collected from medical records of large groups of people to study how diseases progress and which treatments and surgeries work best.
  • During the early phases (phases 1 and 2), researchers assess safety, side effects, optimal dosages and risks/benefits. In the later phase (phase 3), researchers study whether the treatment works better than the current standard therapy. They also compare the safety of the new treatment with that of current treatments. Phase 3 trials include large numbers of people to make sure that the result is valid. There are also less common very early (phase 0) and later (phase 4) phases. Phase 0 trials are small trials that help researchers decide if a new agent should be tested in a phase 1 trial. Phase 4 trials look at long-term safety and effectiveness, after a new treatment has been approved and is on the market.

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. If you need assistance understanding the eligibility criteria, please contact the study team.

Inclusion Criteria:

  • Written informed consent or assent
  • Age ≥ to 16 years
  • Histologically confirmed diagnosis of osteosarcoma with lung metastasis, who have progressed on the prior line of therapy, or relapsed
  • Ineligible for curative pulmonary metastasectomy
  • ECOG performance status of 0-2
  • Measurable disease per RECIST version 1.1 guidelines. At least one measurable lesion must be in the lungs.
  • Eligible subjects are required to have ≥ to 1 line of multi-agent chemotherapy either neoadjuvantly or adjuvantly. Subjects may have had 0-2 lines of therapy for metastatic disease.
  • Measured cardiac ejection fraction ≥ to 50% or the institutional LLN by echocardiogram or MUGA scan.
  • Adequate organ system function.
  • Females must be either non-child bearing potential or have a negative pregnancy test within 3 to 5 days prior to the first dose of study drug.

Exclusion Criteria:

  • Children in care.
  • Prior exposure to VEGFR tyrosine kinase inhibitor (small molecule or antibody) or VEGFR antibody.
  • Prior malignancy. Note: Subjects who have had another malignancy and have been disease-free for 3 years, or subjects with a history of completely resected non-melanomatous skin carcinoma or successfully treated in situ carcinoma are eligible.
  • History or clinical evidence of central nervous system (CNS) metastases or leptomeningeal carcinomatosis, unless previously treated, asymptomatic, and off steroids and anti-seizure medication for 6 months prior to first dose of study drug
  • Clinically significant gastrointestinal abnormalities that may increase the risk for gastrointestinal bleeding.
  • Clinically significant gastrointestinal abnormalities that may affect absorption of investigational product.
  • Presence of uncontrolled infection.
  • Corrected QT interval (QTc) > 480 msecs using Bazett's formula.
  • History of certain cardiovascular conditions within the past 6 months.
  • Class II-IV congestive heart failure, as defined by the New York Heart Association
  • Poorly controlled hypertension [defined as systolic blood pressure (SBP) of ≥ 140 mmHg or diastolic blood pressure (DBP) of ≥ 90mmHg].
  • History of cerebrovascular accident including transient ischemic attack (TIA), pulmonary embolism or untreated deep venous thrombosis (DVT) within the past 6 months.
  • Prior major surgery or trauma within 28 days prior to the protocol-mandated 4-week drug holiday and/or presence of any non-healing wound, fracture, or ulcer.
  • Evidence of active bleeding or bleeding diathesis.
  • Known endobronchial lesions and/or lesions infiltrating major pulmonary vessels that increase the risk of pulmonary hemorrhage.
  • Hemoptysis in excess of 2.5 mL (or one half teaspoon) within 8 weeks of first dose of study drug.
  • Any serious and/or unstable pre-existing medical, psychiatric, or other condition that could interfere with subject's safety, provision of informed consent/assent, or compliance to study procedures.
  • Unable or unwilling to discontinue use of prohibited medications for at least 14 days or five half-lives of a drug, whichever is longer, prior to the first dose of study drug and for the duration of the study treatment.
  • Radiation therapy, minor surgery, tumor embolization, chemotherapy, immunotherapy, biologic therapy, investigational therapy or hormonal therapy within 14 days prior to the protocol-mandated 4-week drug holiday.
  • Administration of any non-oncologic investigational drug within 30 days or five half-lives (whichever is longer) prior to the protocol-mandated 4-week drug holiday.
  • Any ongoing toxicity from prior anti-cancer therapy that is > Grade 1 and/or that is progressing in severity, except alopecia.
  • An untreated tumor growth rate of < 6.1% during the Screening period may exclude some patients.
