A Phase I Study of SB939 in Pediatric Patients With Refractory Solid Tumours and Leukemia
This research is being done because SB939 has been shown to shrink tumours in animals and in some people and seems promising, but we are not sure if it can offer better results than standard treatment.

|Official Title:||A Phase I Study of SB939 in Pediatric Patients With Refractory Solid Tumours and Leukemia|
- Part A: Maximum Tolerated Dose and RP2D in solid tumours [ Time Frame: 24 months ] [ Designated as safety issue: Yes ]
Part A: patients must have recurrent or refractory solid tumours, lymphoma or CNS tumours (excluding diffuse intrinsic pontine gliomas)
Purpose is to determine recommended phase II dose (RP2D) of oral SB939 in pediatric patients with solid tumours, with SB939 administered at a starting dose of 25 mg/m2 (70% of the adult recommended phase II dose), and given orally every other day three times / week (e.g. Monday / Wednesday /Friday OR Tuesday / Thursday / Saturday) for three consecutive weeks, followed by one week off-dosing.
- Part B: Tolerability [ Time Frame: 24 months ] [ Designated as safety issue: Yes ]
Part B: patients must have recurrent or refractory leukemia
Tolerability of the solid tumour RP2D in patients with recurrent or refractory leukemia once the RP2D has been established in solid tumours.
- Part C: Recommended Phase 2 Dose (RP2D) and Tolerability [ Time Frame: 24 months ] [ Designated as safety issue: Yes ]
Part C: patients must have neuroblastoma, or medulloblastoma/CNS primitive neuroectodermal tumour (PNET)
RP2D of oral SB939 in combination with a fixed dose of 13-cisretinoic acid in children with refractory or recurrent neuroblastoma, medulloblastoma / CNS neuroectodermal tumour (PNET), using the recommended dose determined in Part A of this study.
- Pharmacokinetics [ Time Frame: 24 months ] [ Designated as safety issue: No ]characterize the pharmacokinetics of SB939 in a pediatric population
- Anti-tumour activity [ Time Frame: 24 months ] [ Designated as safety issue: No ]antitumour activity of SB939 in pediatric tumours when given as a single agent, and when given in combination with 13-cis-retinoic acid.
|Study Start Date:||September 2010|
|Estimated Study Completion Date:||December 2013|
|Primary Completion Date:||January 2012 (Final data collection date for primary outcome measure)|
Dose Levels for Part A
-1 - 20mg/m2 - oral - Every other day three times/week1 for three consecutive weeks, followed by one week off-dosing
4+ - Previous level + 10mg/m2 - oral - Every other day three times/week1 for three consecutive weeks, followed by one week off-dosing
In Part A of this study, SB939 was given to children with solid tumours. The purpose of Part A of this study is to ind the highest dose of a new drug SB939 that can be giben to children without causing very severe side effects that are tolerable.
In Part B of this study, SB939 will be given to children with leukemia. The purpose of Part B, is to see whether the dose that was determined to be the best dose for patients with solid tumours is also the best dose for children with leukemia.
In Part C of this study, SB939 will be given together with 13-cis-retinoic acid. The purpose of Part C, is to see whether the SB939 dose that was determined to be the best dose in Part A is also the best dose when given in combination with 13-cis-retinoic acid.
