Unspecified cohort for exploratory evaluation. The unspecified histologies must also be rare tumours for which there are no traditional phase II clinical trials and for which there are clinical activity or laboratory data to support the likely sensitivity to the agents. Please call NCIC CTG for consultation prior to registration.
- 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. 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).
- ≥ 16 years.
- Patients must have a life expectancy of at least 12 weeks.
- ECOG performance status 0, 1 or 2.
- Previous Therapy
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.
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.
(must be done within 7 days prior to registration) Hematology Absolute granulocytes: ≥ 1.5 x 109/L Platelets: ≥ 100 x 109/L
ALL Patients Bilirubin ≤ 1.5 x UNL (upper normal limit) AST and ALT ≤ 2.5 x UNL Serum Creatinine ≤UNL or: Creatinine clearance ≤UNL ≥ 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 consent must be obtained according to local Institutional and/or University Human Experimentation Committee requirements. 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 although a sample form will be provided. A copy of the initial full board REB approval and approved consent form must be sent to the central office. The patient 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. 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.
Ineligibility Criteria - ALL Patients
Patients who fulfil any of the following criteria are not eligible for admission to either the sunitinib treatment arm (Arm A) or temsirolimus arm (Arm B) of this study:
Patients with a history of other malignancies, except: adequately treated non-melanoma skin cancer or other solid tumours curatively treated with no evidence of disease for ≥ 3 years.
Patients who have had prior treatment with relevant mTOR or VEGFR, KIT, RET, PDGFR inhibitors. Patients who have had prior treatment with mTOR inhibitors are ineligible for temsirolimus; patients who have had prior treatment with VEGFR, KIT, RET or PDGFR inhibitors are ineligible for sunitinib.
Pregnant or lactating women. Women of childbearing potential must have a urine pregnancy test proven negative within 7 days prior to registration. Men and women of child-bearing potential must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation. Should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately.
Patients with known symptomatic brain metastases (a brain CT is not necessary to rule out brain metastases, unless there is clinical suspicion of CNS involvement). Patients with treated and radiologic or clinical evidence of stable brain metastases, with no evidence of cavitation or hemorrhage in the brain lesion, are eligible providing that they are asymptomatic and do not require corticosteroids (must have discontinued steroids at least 1 week prior to entry).
Patients with known hypersensitivity to the relevant study drug or its components, or compounds of similar chemical or biologic composition.
Patients receiving concurrent treatment with other anti-cancer therapy or other investigational agents.
Patients with serious illness or medical condition which would not permit the patient to be managed according to the protocol including, but not limited to:
- History of significant neurologic or psychiatric disorder which would impair the ability to obtain consent or limit compliance with study requirements
- Active uncontrolled infection
- Any other medical conditions that might be aggravated by treatment
- Serious or non-healing wound, ulcer, or bone fracture.
- Abdominal fistula, gastrointestinal perforation, or intra-abdominal abscess within 28 days of treatment. Patients believed to be at high risk for fistula formation because of the location and extent of their disease should not be enrolled.
