Brief Summary:
This research is being done because there is no treatment that will cure this type of cancer. Although some types of chemotherapy can cause this cancer to shrink for a time, better options are needed.

Condition or disease Intervention/treatment Phase
Advanced Rare Tumours Drug: Sunitinib Drug: Temsirolimus Phase 2

Detailed Description:
The purpose of this study is to find out what effects the study drugs - sunitinib or temsirolimus - will have on this type of cancer. The study will begin by finding out if sunitinib can shrink the cancer. If sunitinib does not work, temsirolimus will be tested next.

Arm Intervention/treatment
Active Comparator: Sunitinib Drug: Sunitinib
50 mg PO daily for 28 days, q 6 weeks (1 cycle=6 weeks or 42 days)

Active Comparator: Temsirolimus Drug: Temsirolimus
25 mg IV weekly (Days 1, 8, 15, 22, 29, 36), q 6 weeks (1 cycle=6 weeks or 42 days)

Primary Outcome Measures :
  1. Objective Response [ Time Frame: Every 4 weeks ]
    Objective response as assessed by RECIST version 1.1 criteria as a 30% decrease in the sum of the longest diameters of the target lesions (partial response) maintained for at least 4 weeks, or complete disappearance of disease and cancer related symptoms (complete response), also maintained for at least 4 weeks. Early progression is defined as progressive disease at or prior to the first assessment. The 95% confidence interval for response rate will be calculated. The median and range of the duration of response will be assessed

Secondary Outcome Measures :
  1. Efficacy Outcomes [ Time Frame: 48 months ]
    • Response duration: median and range
    • Time to progression: median, 95% confidence interval
    • Progression free survival: median, 95% confidence interval
    • Overall survival: median, 95% confidence interval
    • Comparison of the time to first and second progression for patients who receive sunitinib and temsirolimus in sequence.

  2. Translational Research [ Time Frame: 48 months ]
    Primary tumour tissue specimens and baseline blood samples, will be obtained from all subjects prior to first dose for genetic analysis and other evaluation. In addition, optional for responding patients will be a fresh tumour biopsy at time of progression and also optional for patients entered in the second stage of accrual for any disease cohort will be fresh tumour biopsy at baseline.

  3. Safety Monitoring [ Time Frame: Daily up to an expected average of 4 weeks after treatment ]
    Adverse events will be monitored on an ongoing basis by the central office and their frequencies reported annually at investigators' meetings.

    • Patients must have unresectable, locally advanced or metastatic disease for which there are no known life prolonging standard therapies.
    • Patients must have tumour tissue from their primary tumour available
    • Presence of clinically and/or radiologically documented disease. At least one site of disease must be unidimensionally measurable as follows:

    Chest x-ray ≥ 20 mm Ct scan (with slice thickness of ≤ 5 mm) - ≥ 10 mm --> Longest diameter Physical exam (using calipers) - ≥ 10 mm Lymph nodes by ct scan - ≥ 15 mm --> Measured in short axis

    All radiology studies must be performed within 21 days prior to registration (within 28 days if negative).

    • Patients must have a life expectancy of at least 12 weeks.
    • ECOG performance status 0, 1 or 2.
    • Previous Therapy Chemotherapy: Patients may have received prior chemotherapy (no limit on number of prior regimens), however no prior treatment with relevant mTOR or VEGFR, KIT, RET, PDGFR inhibitors is permitted (i.e. to be eligible for sunitinib: no prior treatment with VEGFR, KIT, RET or PDGFR inhibitors permitted; to be eligible for temsirolimus: no prior treatment with mTOR inhibitors permitted). A minimum of 28 days (4 weeks) must have elapsed since the last dose of chemotherapy prior to registration. Patients must have recovered from any treatment related toxicities prior to registration.

    Radiation: Patients may have had prior radiation therapy. A minimum of 28 days (4 weeks) since the last dose of radiation must have elapsed prior to registration (exceptions may be made for low dose, palliative radiotherapy. Patients must have recovered from any acute toxic effects from radiation prior to registration.

    Previous surgery: is permitted provided that wound healing has occurred and at least 28 days have elapsed prior to registration if surgery was major.

    Laboratory Requirements:

    (must be done within 7 days prior to registration) Hematology Absolute granulocytes: ≥ 1.5 x 10^9/L Platelets: ≥ 100 x 10^9/L


    ALL Patients Bilirubin ≤ 1.5 x UNL (upper normal limit) AST and ALT ≤ 2.5 x UNL Serum Creatinine ≤UNL or: Creatinine clearance ≥ 60ml/min


    TEMSIROLIMUS Arm Only Fasting cholesterol ≤ 9.0 mmol/L Fasting triglycerides ≤ 4.56 mmol/L

    * Creatinine clearance to be measured directly by 24 hour urine sampling or as calculated by Cockcroft Formula: Females: GFR = 1.04 x (140-age) x weight in kg serum creatinine in μmol/L Males: GFR = 1.23 x (140-age) x weight in kg serum creatinine in μmol/L

    • Patient or guardian consent must be obtained on all patients according to local Institutional and/or University Human Experimentation Committee requirements. Children > 8 years old whose parent or guardian has signed consent on their behalf may also sign assent if desired. It will be the responsibility of the local participating investigators to obtain the necessary local clearance, and to indicate in writing to the NCIC CTG Study Coordinator that such clearance has been obtained, before the trial can commence in that centre. Because of differing requirements, a standard consent form for the trial will not be provided but a sample form is provided. A copy of the initial full board REB approval and approved consent form must be sent to the central office. The patient or their parent/legal guardian must sign the consent form prior to registration. Please note that the consent form for this study must contain a statement which gives permission for the NCIC CTG and monitoring agencies to review patient records.
    • Patients must be accessible for treatment, response assessment and follow-up. Patients registered on this trial must be treated and followed at the participating centre. This implies there must be reasonable geographical limits (for example: 1 ½ hour's driving distance) placed on patients being considered for this trial. (Call the NCIC CTG office at 613-533-6430 if questions arise regarding the interpretation of this criterion.) Investigators must assure themselves the patients registered on this trial will be available for complete documentation of the treatment, adverse events, and follow-up.

    In accordance with NCIC CTG policy, protocol treatment is to begin within 5 working days of patient registration.
