Study of Vinblastine and Sirolimus in Children With Recurrent/Refractory Solid Tumours Including CNS Tumours

• Status: Completed
• Trial end date: 2012-04-01
• Target enrollment: 0
• Participant gender: All

Summary

This study is a Phase I study using vinblastine and sirolimus in patients with relapsed solid tumors including selected brain tumors and lymphoma. The investigators hypothesis is that the combination administration of weekly vinblastine and sirolimus is safe.

• Phase: Phase 1
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: The Hospital for Sick Children
• Collaborators: Solving Kids' Cancer; Solving Kids’ Cancer
• Treatments: Everolimus; Sirolimus; Vinblastine

Criteria

Inclusion Criteria:

1. Age: 0-21 years at the time of diagnosis

2. Diagnosis: Histologic verification at either the time of original diagnosis or relapse of solid tumor including CNS tumors or lymphomas

3. Disease Status: All refractory/recurrent solid tumors including CNS tumors (all Diffuse Intrinsic Brain Stem Gliomas excluded) and lymphomas that have relapsed after, or are refractory to, a chemotherapy-containing treatment regimen

4. Measurable disease:

• Measurable tumor by CT or MRI defined as >10 mm by spiral CT in at least one dimension

5. Current disease state must be one for which there is currently no known curative therapy

6. A negative urine pregnancy test is required for female participants of child bearing potential

7. Organ Function Requirements:

• adequate liver function as defined by AST or ALT < 5 x upper limit of normal, bilirubin ≤1.5 X upper limit of normal

• adequate renal function: Serum creatinine < 1.5 X upper limit of normal for age

8. Adequate Bone Marrow Function Defined as:

• ANC ≥ 1000/mm3, platelets ≥ 75,000/mm3 and hemoglobin ≥ 90 g/L

• Transfusions are permitted to meet these platelet and Hgb criteria, if the patient is known to have a history of bone marrow involvement with tumor

• Patients with platelet counts < 75,000/ mm3 who are refractory to platelet transfusions are not eligible for this study

• Patients requiring transfusions of platelets or RBC to meet eligibility criteria will not be evaluable for platelet or hgb/hct hematological toxicity

9. Lansky Play Score (for patients < 16 years of age) must be more than 50 and/or ECOG performance status (for patients ≥ 16 years of age) must be 0 to 2

10. Specific requirements for Neuroblastoma patients Stratum:

• MIBG scan with positive uptake at minimum of one site (MIBG not required if subject's neuroblastoma is previously determined to not uptake MIBG and no measurable disease)

• Bone marrow with tumor cells seen on routine morphology (not by NSE staining only) of bilateral aspirate and /or biopsy on one bone marrow sample

11. Written informed consent

Exclusion Criteria:

1. Lansky score <50%

2. Investigational Drugs: Patients who are currently receiving another investigational drug(s)

3. Previous treatment with Vinblastine and/or mTor inhibitors

4. Anti-cancer Agents: Patients who are currently receiving other anticancer agents. Patients must have fully recovered from the effects of prior chemotherapy, generally at least 3 weeks from the most recent administration (6 weeks for nitrosoureas)

5. Infection: Patients who have an uncontrolled infection are not eligible until the infection is judged to be well controlled

6. Patients who, in the opinion of the investigator, may not be able to comply with the safety monitoring requirements of the study, or in whom compliance is likely to be suboptimal

7. One week from usage of hematopoietic Growth Factor

8. Patients who are refractory to platelet transfusions

9. Brain Stem Glioma patients
