SF1126 for Patients With Relapsed or Refractory Neuroblastoma
Study Details
Study Description
Brief Summary
SF1126 is a novel inhibitor of PI3 kinase and mTOR that includes an active moiety (consisting of LY294002) linked to an RGDS tetrapeptide that targets the active agent to integrin expressing tissues. In this first pediatric phase 1 trial of SF1126, dose escalation will follow a 3+3 dose escalation design. Once a recommended phase 2 pediatric dose is identified, an expansion cohort of 10 patients with tumors with MYCN amplification, Mycn expression, or Myc expression will be treated.

Detailed Description
Inhibitors of the PI3 kinase pathway have demonstrated preclinical activity in neuroblastoma. This activity may derive in part from destabilizing Mycn protein, impeding tumor angiogenesis, and/or other effects. SF1126 is a novel inhibitor of PI3 kinase and mTOR that includes an active moiety (consisting of LY294002) linked to an RGDS tetrapeptide that targets the active agent to integrin expressing tissues. In preclinical studies, SF1126 results in marked concentration of LY294002 into tumors. In an adult phase 1 trial, a maximum tolerated dose of SF1126 was not identified up to doses of 1110 mg/m2 administered intravenously twice weekly on a continuous schedule. In this first pediatric phase 1 trial of SF1126, dose escalation will follow a 3+3 dose escalation design. Once a recommended phase 2 pediatric dose is identified, an expansion cohort of 10 patients with tumors with MYCN amplification, Mycn expression, or Myc expression will be treated. All patients will participate in mandatory pharmacokinetic testing. Additional optional correlative studies will evaluate potential predictive markers and potential pharmacodynamic markers, including PTEN and PIK3CA aberrations, Myc / Mycn expression, and Myc / pS6 levels in peripheral blood mononuclear cells.

Outcome Measures
Primary Outcome Measures
- Toxicities, based on the CTCAE criteria, will be used to measure the severity of adverse events [6 months]
Toxicity will be graded using the CTCAE criteria, version 4. The CTCAE provides descriptive terminology and a grading scale for each adverse event listed. A copy of the CTCAE can be downloaded from the CTEP home page (http://ctep.cancer.gov).
Secondary Outcome Measures
- Evaluation of response [After day 1 of week 4 of cycles 2, 4, and 6]
Response will be determined by the evaluation of CT/MRI scans and bone marrow biopsy.
- Pharmacokinetics: Parameters include AUC, clearance, Cmax, Tmax, & terminal half-life for SF1101 & SF1174. With rapid conversion of SF1126 to SF1101, only AUC, clearance, Cmax & Tmax are calculated for SF1126. [Day 1, cycle 1]
Plasma samples will be collected from patients at 9 time points on Day 1 of the first cycle.
