A Phase I Study of IMC-A12 in Combination With Temsirolimus in Pediatric Patients With Recurrent or Refractory Solid Tumors

June 30, 2017 updated by: National Cancer Institute (NCI)

A Phase I Study of IMC-A12 (Anti-Insulin-like Growth Factor-I Receptor Monoclonal Antibody) in Combination With CCI-779 (Temsirolimus) in Pediatric Patients With Recurrent or Refractory Solid Tumors

Background:

- IMC-A12 is an experimental substance designed to inhibit a protein called Type I Insulin-Like Growth Factor Receptor (IGF-1R), which can be found on cancer cells and can promote cancer growth. Temsirolimus is a drug that the U.S. Food and Drug Administration has approved to treat advanced renal cell carcinoma in adults. Researchers do not know if the combination of IMC-A12 and temsirolimus will work in children, but want to determine whether these two drugs may be an effective treatment for recurrent tumors.

Objectives:

  • To determine the safety and effectiveness of IMC-A12 and temsirolimus in treating children and adolescents with solid tumors.
  • To determine possible side effects of the combination of IMC-A12 and temsirolimus.

Eligibility:

- Children and adolescents between 12 months and 21 years of age who have solid tumors that have not responded to or have relapsed after standard treatment.

Design:

  • Participants will be screened with a medical history, physical examination, and imaging studies.
  • Participants will receive IMC-A12 and temsirolimus in 28-day cycles of treatment. IMC-A12 will be given as an infusion over 1 hour, once a week, for 4 weeks. Temsirolimus will also be given after IMC-A12 over 30 minutes, once a week, for 4 weeks.
  • Participants may continue to receive IMC-A12 and temsirolimus for up to 2 years unless serious side effects develop or the treatment stops being effective.
  • Participants will have additional physical exams, blood and urine tests, and imaging studies regularly during each treatment cycle.
  • Participants will be followed at regular intervals after the end of the study to collect tumor response and progression data....

Detailed Description

Background

  • IMC-A12 is a fully recombinant IgG1monoclonal antibody to the insulin-like growth factor receptor (IGFR). It acts as an antagonist of IGF-1 and IGF-2 ligand binding and blocks ligand binding to IGF-1R and inhibits downstream signaling of the two major insulin-like growth factor pathways: MAPK and PI3K/AKT.
  • Temsirolimus is a small molecule inhibitor of mTOR, which like rapamycin and everolimus forms a complex with FK506-binding protein (FKBP)12 and mTOR, inhibiting mTOR and leading to anti-proliferative effects, including G1 phase cell cycle arrest and apoptosis.
  • Inhibition of mTOR signaling leads to upregulation of IGF-1R signaling which leads to activation of the PI3K/AKT/mTOR pathway. Pediatric pre-clinical models have demonstrated synergistic anti-tumor effects combining IGF-1R antibodies and mTOR inhibitors.

Objectives

  • To determine the maximum tolerated dose (MTD) and recommended Phase II dose of IMC-A12 (anti-insulin growth factor-1 receptor monoclonal antibody) administered as an intravenous infusion once weekly in combination with temsirolimus administered intravenously once weekly to children with refractory solid tumors.
  • To define the toxicities of the combination regimen and characterize the pharmacokinetics of IMC-A12 in combination with temsirolimus in this patient population.
  • Secondary objectives include defining in a preliminary fashion antitumor activity, assessing biologic activity of IMC-A12 and temsirolimus and assessing the incidence of IGFR expression and mTOR pathway activation in recurrent or refractory solid tumors of childhood.

Eligibility

  • Patients > 12 months and less than or equal to 21 years of age with a diagnosis and histologic verification (except patients with intrinsic brain stem tumors, optic pathway gliomas or pineal tumors and elevations of serum or CSF alpha-fetoprotein or beta-HCG) of measureable or evaluable relapsed or refractory solid tumors. Current disease state must be one for which there is no known curative therapy, or therapy proven to prolong survival.
  • Must have fully recovered from acute toxic effects from all prior therapy, which has been completed within the specified prior time frame.
  • Have adequate organ function as determined by laboratory evaluation including normal random or fasting blood glucose within the upper normal limits for age and grade < 2 serum cholesterol and triglyceride levels.
  • Subjects with uncontrolled infection, known type I or type II diabetes mellitus, known bone marrow involvement or who have received prior monoclonal antibody therapy targeting IGF-1R or temsirolimus are not eligible.

Design

  • This is a phase I study of IMC-A12 administered every 7 days as a 1-hour intravenous infusion at a starting dose of 6 mg/kg. Temsirolimus will be administered intravenously over 30 minutes immediately after IMC-A12 on a once weekly schedule, at a starting dose of 15 mg/m(2).
  • One cycle of therapy is considered to be 28 days. Therapy may continue for up to 2 years in the absence of progressive disease or unacceptable toxicity.
  • All patients will have required trough blood samples for pharmacokinetic analysis of IMC-A12 and temsirolimus and immunogenicity studies collected at the same time as select routine safety labs. Optional participation in additional pharmacokinetic studies and correlative biology studies will be offered.
