Temsirolimus and Valproic Acid in Treating Young Patients With Relapsed Neuroblastoma, Bone Sarcoma, or Soft Tissue Sarcoma

22 december 2016 uppdaterad av: UNC Lineberger Comprehensive Cancer Center

A Multi-center Phase I Trial of Temsirolimus in Combination With Valproic Acid in Children and Adolescents With Multiply Relapsed Pediatric Solid Tumors

RATIONALE: Drugs such as temsirolimus and valproic acid may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Valproic acid may also stop the growth of solid tumors by blocking blood flow to the tumor.

PURPOSE: This phase I trial is studying the side effects and the best dose of temsirolimus when given together with valproic acid in treating young patients with relapsed neuroblastoma, bone sarcoma, or soft tissue sarcoma.

Studieöversikt

Detaljerad beskrivning

OBJECTIVES:

Primary

  • To identify the maximum-tolerated dose of temsirolimus in combination with valproic acid in highly pretreated pediatric patients with refractory solid tumors.

Secondary

  • To estimate the objective response rate in patients treated with this regimen.
  • To estimate the progression-free survival of patients treated with this regimen.
  • To explore the association between tumor IGF-IR, mTOR expression, HDAC, autophagy biomarkers, and sera levels of temsirolimus, valproate, and VEGF-A with toxicity and disease response.
  • To evaluate the ability of selected member divisions of a newly developed North Carolina-based pediatric oncology consortium to cooperate in clinical trials.

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

Patients receive temsirolimus IV over 30-60 minutes on days 1, 8, 15, and 22 and oral valproic acid* 3 times daily on days 1-28. Treatment repeats every 28 days for up to 12 courses in the absence of disease progression or unacceptable toxicity.

Blood samples are collected at baseline and periodically during study for pharmacokinetic and VEGF-A studies. Tumor tissue samples from archived biopsy are also analyzed for IGF-IR, mTOR expression, HDAC, and autophagy biomarkers.

After completion of study therapy, patients are followed every 3 months for 1 year, every 4 months for 2 years, and then every 6 months for 2 years.

NOTE: * Doses of valproic acid are titrated beginning 3-7 days prior to starting temsirolimus to achieve plasma levels of 75-100 µg/mL.

Åtgärdsbeskrivning
Tidsram
Maximum tolerated dose (MTD) of temsirolimus in combination with valproic acid
Tidsram: 4 weeks
The planned starting dose of Temsirolimus is 60mg/M2. The traditional 3+3 design will be used, where the MTD is defined as the dose with the probability of a DLT of 0.20

Sekundära resultatmått

Resultatmått
Åtgärdsbeskrivning
Tidsram
Objective response rate
Tidsram: every 12 weeks
