Oral Liquid 13-cis-retinoic Acid (13-CRA) (My-CRA)

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT03291080
Recruitment Status : Completed
First Posted : September 25, 2017
Last Update Posted : February 24, 2020
Information provided by (Responsible Party):
Nova Laboratories Limited

Brief Summary:
An open label, randomised, multiple dose, cross-over relative bioavailability and pharmacokinetics trial of a novel oral liquid and capsule formulations of 13-CRA administered to patients from 0 months - < 21 years.

Condition or disease Intervention/treatment Phase
Neuroblastoma Drug: Liquid 13-Cis Retinoic Acid Drug: Extracted capsules 13-CRA Phase 1 Phase 2

Detailed Description:

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.

    Pharmacokinetic parameter

  2. Maximum plasma concentration (Cmax) [ Time Frame: On day 1 and 14 of treatment ]
    Pharmacokinetic parameter

  3. Area under plasma concentration time curve (AUC) [ Time Frame: On day 1 and 14 of treatment ]
    Pharmacokinetic parameter

  4. Half-life (t1/2) [ Time Frame: On day 1 and 14 of treatment ]
    Pharmacokinetic parameter

  5. Clearance (CL/F) [ Time Frame: On day 1 and 14 of treatment ]
    To determine clearance pharmacokinetics of 13-CRA

  6. Volume of distribution (V/F) [ Time Frame: On day 1 and 14 of treatment ]
    To determine volume of distribution pharmacokinetics of 13-CRA

Other Outcome Measures:
  1. Number of participants with treatment-related adverse events as assessed by CTCAE v4.0 [ Time Frame: Over 2 months treatment and 14 day follow up ]
    Number of participants with treatment-related adverse events as assessed by CTCAE v4.0

Ages Eligible for Study:   up to 21 Years   (Child, Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  1. Male or female aged from 0 years to < 21 years of age.
  2. Patient with high risk neuroblastoma, or unresectable, unfavourable histology intermediate risk neuroblastoma the latter age ≥ 18 months at diagnosis
  3. Patient who is scheduled to receive at least two treatment cycles of 13-CRA.
  4. Patient who cannot swallow 13-CRA capsules (i.e. requires extraction of 13-CRA from the capsules).
  5. Negative pregnancy test for females of child-bearing potential before initiation of treatment, and sexually active patients and partners agreeing to undertake adequate contraceptive measures (see section 4.5).
  6. Provision of a single or double lumen central venous catheter for sampling (i.e. already in place).
  7. Parent(s)/legal guardian able and willing to provide written informed consent for the patient to take part in the trial.
  8. Where applicable, the patient should assent to undergo blood sampling for pharmacokinetic purposes and to allow physiological measurements to be made.

Exclusion Criteria:

  1. Any clinically significant medical condition or abnormality, which, in the opinion of the investigator, might compromise the safety of the patient or which might interfere with the trial.
  2. Diagnosis of high-risk neuroblastoma (HRNBL) which is currently being treated on the SIOPEN HRNBL trial (patients who have exited this trial will be eligible).
  3. Known allergy to 13-CRA or any of the excipients.
  4. Inadequate contraception measures in females of childbearing age.
  5. Receiving concomitant treatment with tetracyclines.

Prior to each cycle:

  1. Total bilirubin ≤ 1.5 x normal, and (SGPT) ALT ≤ 5 x normal. Veno-occlusive disease if present, should be stable or improving.
  2. Skin toxicity no greater than CTCAE Grade 1(10)
  3. Serum triglycerides <5.65mmol/L.
  4. No haematuria and / or proteinuria on urinalysis.
  5. Serum calcium ≤ 2.9mmol/L.
  6. Serum creatinine based on age / gender as follows:

Withdrawal Criteria:

  1. Positive pregnancy test - pregnancy testing will be undertaken before treatment commences and routinely before each course of treatment in females of childbearing potential. If a patient is found to be pregnant during the trial, the next course of treatment will not be given until the pregnancy has been discussed with the treating clinician, and the patient will be withdrawn from the trial whether or not treatment is continued.
  2. Request of the patient, for any reason.
  3. Discretion of the investigator.
