A Phase 1 Study of Temsirolimus in Combination With Irinotecan and Temozolomide in Children, Adolescents, and Young Adults With Relapsed or Refractory Solid Tumors


This phase I trial is studying the side effects and the best dose of temsirolimus when given
together with irinotecan hydrochloride and temozolomide in treating younger patients with
recurrent or refractory solid tumors. Temsirolimus may stop the growth of tumor cells by
blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as
irinotecan hydrochloride and temozolomide, work in different ways to stop the growth of
tumor cells, either by killing the cells or by stopping them from dividing. Giving
temsirolimus together with combination chemotherapy may kill more tumor cells.


PRIMARY OBJECTIVES:

I. To estimate the maximum tolerated dose (MTD) or recommended Phase 2 dose and schedule of
temsirolimus administered in combination with irinotecan and temozolomide every three weeks
to children with recurrent or refractory solid tumors.

II. To define and describe the toxicities of this regimen in these patients.

SECONDARY OBJECTIVES:

I. To preliminarily define the antitumor activity of this regimen in these patients.

II. To collect preliminary data regarding the biologic effects of temsirolimus on proteins
involved in signaling pathways of interest in these patients. (Exploratory)

OUTLINE: This is a multicenter study, dose-escalation study of temsirolimus.

Patients receive temsirolimus IV over 30 minutes on days 1 and 8 or on days 1, 8, and 15 and
irinotecan hydrochloride and oral temozolomide on days 1-5. Courses repeat every 21 days for
up to 12 months in the absence of disease progression or unacceptable toxicity.

Some patients undergo bone marrow collection at baseline and during study for
temsirolimus-induced changes in mTOR pathway proteins by flow cytometric analysis and
immunoblotting.

After completion of study therapy, patients are followed up for 30 days.

Inclusion Criteria:

survival with an acceptable quality of life

platelet infusions)

- At least 6 weeks since prior immunotherapies (e.g., tumor vaccines)

- At least 3 half-lives since prior monoclonal antibody therapy

- At least 2 weeks since prior local palliative radiotherapy (small port)

- At least 24 weeks since prior total-body irradiation, craniospinal radiotherapy
(RT), or RT to ≥ 50% to the pelvis
