Description of intervention(s) / exposure
This is an open label, Phase I, multicentre study evaluating the maximum tolerated dose of LBH589 (Panobinostat) in paediatric patients with refractory solid tumours including CNS tumours.
Patients will be separated into one of two groups depending on age and registered into escalating dose levels.
Group 1: patients < 12 years of age including infants
Group 2: patients >= 12 years - < 18 years
A course of treatment is 3 weeks and LBH589 will be administered intravenously (i.v.) weekly as a 30 min infusion for week 1 and week 2 with week 3 for rest and evaluation. The starting dose is 15mg/m2 and inter-patient dose escalation or reductions will occur, in successive cohorts, at increments of 5mg/m2 with corresponding dose levels of 20mg/m2, 25mg/m2, 30 mg/m2 in cohorts of 3-6 patients until an MTD is reached. Patients may be recruited sequentially to the appropriate age range independent of recruitment to the other age range. Therefore these two recruitment groups will be run in parallel with an independent MTD dosing level being established for each group. Treatment can be continued for up to 17 courses or for up to 12 months.

Intervention assignment
Other
Other design features
Patients will be separated into one of two groups depending on age and registered into escalating doses. Additional patients in each group will be enrolled depending on the number of toxicities observed. Once the MTD has been determined for each age group, additional patients may be recruited such that a minimum of six patients will be observed at that dosing level. Additional pharmacokinetic data will then be obtained at the MTD dosing level.

Summary
Brief summary
This is a study examining the use of a new anti-cancer drug called LBH589 in children with solid and central nervous system (CNS) tumours. It is only for children where a tumour does not respond to initial conventional therapies (refractory). At this time there is no standard treatment available for many children who have a refractory solid or CNS tumour. Faulty regulation of a cell protein (enzyme) in the body called a histone deacetylase (HDAC) is known to be present in many human cancers. It changes cell structures and weakens the activity of good cancer killing genes. LBH589 is a new investigational drug that can increase the activity of these good genes by reacting with the HDAC cell protein. It is hoped it will help kill the tumour. Research studies in the laboratory using LBH589 have shown a strong response against tumour cells. In addition LBH589 has shown anti-tumour activity in studies of adult cancer patients. LBH589 is now being investigated in clinical trials of solid and haematological tumours in adults. LBH589 is an investigational or experimental anti-cancer agent that has not yet been approved by either the Food and Drug Administration (FDA) or the Therapeutic Goods Administration (TGA). The drug has however been shown to be safe when given to adults on the schedule that will be used in this study. This study is assessing the dose levels that can be safely tolerated in children with solid and CNS tumours.
