Purpose

A study to find out whether olaparib is safe and well tolerated when administered to children and adolescents with solid tumours.

Detailed Description

      A Phase I open-label, multicentre study to determine the RP2D of olaparib monotherapy in the
      paediatric population, and to evaluate the safety, tolerability, PK, PDx and preliminary
      efficacy of olaparib monotherapy in paediatric patients from ≥6 months to <18 years of age at
      enrolment, with relapsed or refractory non-CNS solid tumours for whom there are no standard
      treatment options. It is anticipated that eligible patients fulfilling all of the inclusion
      criteria and none of the exclusion criteria, will include but will not be limited to those
      with osteosarcoma, rhabdomyosarcoma, non-rhabdomyosarcoma soft tissue sarcoma, Ewing Sarcoma
      and neuroblastoma.

Cohort A: ≥12 to <18 yearsExperimentalPatients will receive a single dose of olaparib on Day 1, followed by initiation of bd continuous dosing from Day 2 onwards. Olaparib tablets should be taken at the same time each day (morning and evening), approximately 12 hours apart with one glass of water. The tablets should be swallowed whole and not chewed, crushed, dissolved or divided. Olaparib tablets can be taken with or without food, with the exception of Day 8 (a PK sampling day) when patients aged ≥3 years old receiving tablets should take olaparib at least 1 hour after food and should refrain from eating for up to 2 hours afterwards.

Olaparib tablets should be taken at the same time each day (morning and evening), approximately 12 hours apart with one glass of water. The tablets should be swallowed whole and not chewed, crushed, dissolved or divided.

Cohort C: ≥6 months to <6 yearsExperimentalPatients will receive a single dose of olaparib on Day 1, followed by initiation of bd continuous dosing from Day 2 onwards, using the AAF when available (if required). Olaparib tablets should be taken at the same time each day (morning and evening), approximately 12 hours apart with one glass of water. The tablets should be swallowed whole and not chewed, crushed, dissolved or divided. Olaparib tablets/AAF can be taken with or without food, with the exception of Day 8 (a PK sampling day) when patients aged ≥3 years old receiving tablets should take olaparib at least 1 hour after food and should refrain from eating for up to 2 hours afterwards.

Signal identificationExperimentalA secondary analysis of response in patients recruited into the signal identification phase will be conducted. Patients included in this analysis must have documented evidence of a deleterious or suspected deleterious germline or tumour HRR gene mutation. A minimum of 10 patients across age and dose cohorts with deleterious or suspected deleterious HRR mutations will be enrolled.

             (measurable and/or non measurable) OR disease evidenced by uptake of
             meta-iodobenzylguanidine- (MIBG) or fluorodeoxyglucose positron emission tomography
             (FDG-PET) scans.

          -  Adequate performance status, organ, and marrow function and adequate weight to obtain
             blood samples for both safety laboratory assessments and PK analysis.
