|Condition or disease||Intervention/treatment||Phase|
|Neuroblastoma||Drug: Liquid 13-Cis Retinoic Acid Drug: Extracted capsules 13-CRA||Phase 1 Phase 2|
All patients requiring at least two cycles of 13-CRA therapy will be eligible for recruitment into the trial.
13-CRA will be prescribed to patients according to local treatment protocols at each clinical site. The dose administered will be 200mg/m2/day for both test and reference product. Patients with a body weight of ≤12kg will receive a dose of 160 mg/m2.
The pharmacokinetics of 13-CRA liquid (test product) and 200mg/m2/day extracted from capsule (reference product) will be evaluated over two months. Prior to the initiation of 13-CRA treatment as part of the trial, patients will be randomised to receive either liquid or capsule formulation in "My-CRA month 1". The patients will then cross-over to the alternative formulation in "My-CRA month 2". The patients on the trial who require further treatment will revert to standard therapy i.e. 13-CRA extracted from capsules according to local practice.
