  • Feasible Dose: Pediatric [ Time Frame: After the first 6 weeks of Induction ]
    The dose of pazopanib that is feasible when given in combination with radiation or chemoradiation in pediatric unresected intermediate- and high-risk NRSTS patients. Initially, up to 10 patients (minimum of 3 patients ≥ 2 and < 18 years of age and 3 patients ≥ 18 years of age) eligible for each of the two study cohorts were non-randomly assigned (to generate 8 patients evaluable for toxicity) to receive treatment with pazopanib at dose level 1. A protocol-defined list of pazopanib-associated adverse events were defined as dose-limiting toxicities. The pazopanib dose determined to be feasible was based on the number of patient-reported dose-limiting toxicities encountered.

Brief Title  ICMJE Radiation Therapy With or Without Combination Chemotherapy or Pazopanib Before Surgery in Treating Patients With Newly Diagnosed Non-rhabdomyosarcoma Soft Tissue Sarcomas That Can Be Removed by Surgery
Official Title  ICMJE Pazopanib Neoadjuvant Trial in Non-Rhabdomyosarcoma Soft Tissue Sarcomas (PAZNTIS): A Phase II/III Randomized Trial of Preoperative Chemoradiation or Preoperative Radiation Plus or Minus Pazopanib (NSC# 737754)
Brief Summary This randomized phase II/III trial studies how well pazopanib, when combined with chemotherapy and radiation therapy or radiation therapy alone, work in the treatment of patients with newly diagnosed non-rhabdomyosarcoma soft tissue sarcomas that can eventually be removed by surgery. Radiation therapy uses high energy x-rays to kill tumor cells. Drugs used in chemotherapy, such as ifosfamide and doxorubicin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Pazopanib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. It is not yet known whether these therapies can be safely combined and if they work better when given together in treating patients with non-rhabdomyosarcoma soft tissue sarcomas.
Detailed Description

PRIMARY OBJECTIVES:

I. To identify the dose of pazopanib that is feasible when given in combination with radiation or chemoradiation in pediatric and adult patients newly diagnosed with unresected intermediate- and high-risk non rhabdomyosarcoma soft tissue sarcomas (NRSTS).

II. To compare the rates of near complete pathologic response (> 90% necrosis) with the addition of pazopanib to preoperative chemoradiation versus preoperative chemoradiation alone for potentially resectable > 5 cm, grade 2 or 3 intermediate to high risk chemotherapy-sensitive NRSTS in the phase II portion of the study for this cohort.

III. To compare the rates of near complete pathologic response (> 90% necrosis) with the addition of pazopanib to preoperative radiotherapy versus preoperative radiotherapy alone for potentially resectable intermediate to high risk adult and pediatric NRSTS in the phase II portion of the study for this cohort (using a phase II decision rule to go onto the phase III portion of the study).

IV. To compare the rates of event-free survival (EFS) with the addition of pazopanib to preoperative radiotherapy versus preoperative radiotherapy alone for localized intermediate to high risk adult and pediatric NRSTS in the phase III portion of the study for this cohort if the phase II decision rule is passed.

SECONDARY OBJECTIVES:

I. To estimate the rates of local failure, regional failure, distant metastasis free survival, disease-free survival, and overall survival with the addition of pazopanib to preoperative chemoradiation or preoperative radiation in intermediate to high risk adult and pediatric NRSTS.

II. To compare the pattern of recurrence (local, regional and distant) between preoperative chemoradiation or radiation with the addition of pazopanib for adult and pediatric NRSTS.

III. To define the toxicities of ifosfamide and doxorubicin chemotherapy and radiation when used in combination with pazopanib in intermediate to high risk adult and pediatric NRSTS.

IV. To define the toxicities of preoperative radiotherapy when used in combination with pazopanib in intermediate to high risk adult and pediatric NRSTS.

EXPLORATORY OBJECTIVES:

I. To gain insight into the disease biology of childhood and adult NRSTS through analysis of actionable mutations and whole genome sequencing.

II. To determine if microvessel density and circulating tumor deoxyribonucleic acid (DNA) predict response to pazopanib and outcome.

III. To determine the effect of pazopanib on doxorubicin exposure in children and adults with NRSTS.

IV. To evaluate change in fludeoxyglucose F 18 (FDG) positron emission tomography (PET) maximum standard uptake value (SUVmax) from baseline to week 10 or 13 in patients with unresected tumors and to correlate this change with pathologic response and EFS.

V. To compare the rate of response by standard imaging and pathologic assessment to determine which correlates better with local tumor control, distant tumor control, EFS, and overall survival.

  • CYP3A4 Inducers: patients chronically receiving drugs that are known potent CYP3A4 inducers within 14 days prior to study enrollment, including but not limited to carbamazepine, phenobarbital, phenytoin, rifampin, and St. John's wort are not eligible (with the exception of glucocorticoids)
  • Certain medications that are associated with a risk for QTc prolongation and/or Torsades de Pointes, although not prohibited, should be avoided or replaced with medications that do not carry these risks, if possible
  • Subjects with any condition that may impair the ability to swallow or absorb oral medications/investigational product including:

    • Any lesion, whether induced by tumor, radiation or other conditions, which makes it difficult to swallow capsules or pills
    • Prior surgical procedures affecting absorption including, but not limited to major resection of stomach or small bowel
    • Active peptic ulcer disease
    • Malabsorption syndrome

    • Active peptic ulcer disease
    • Known intraluminal metastatic lesions
    • Inflammatory bowel disease (e.g., ulcerative colitis, Crohn's disease) or other gastrointestinal conditions which increase the risk of perforation
    • History of abdominal fistula, gastrointestinal perforation or intra-abdominal abscess within 28 days prior to beginning study treatment

    • Class III or IV heart failure as defined by the New York Heart Association (NYHA) functional classification system; a subject who has a history of class II heart failure and is asymptomatic on treatment may be considered eligible
  • History of serious or non-healing wound, ulcer, or bone fracture
  • Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements
  • Patients who are unable to swallow whole tablets are not eligible
  • Patients with a body surface area < 0.5 m^2 are not eligible
  • Human immunodeficiency virus (HIV)-positive subjects on combination antiretroviral therapy are ineligible because of the potential for pharmacokinetic interactions with pazopanib; in addition, these subjects are at increased risk of lethal infections when treated with marrow-suppressive therapy
  • Patients who are receiving any other investigational agent(s)
  • Pregnancy and breast feeding:

    • Female patients who are pregnant are ineligible due to risks of fetal and teratogenic adverse events as seen in animal/human studies
