About this study

Official title: A Phase I, Open-label, Parallel Group Study to Investigate Olaparib Safety and Tolerability, Efficacy and Pharmacokinetics in Paediatric Patients With Solid Tumours

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

Read the 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 solid or primary CNS tumours (excluding lymphoid malignancies) 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, neuroblastoma, medulloblastoma and glioma

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • OlaparibDrug

    Patients will receive a single dose of olaparib on Day 1, followed by initiation of bd continuous dosing from Day 2 onwards. Olaparib 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. 25 and 100 mg tablet strengths available for ages ≥3 to <18 years. AAF available for ≥0.5 to <6 years; The AAF is a sprinkle capsule formulation, available in dose strengths of 15 mg and 19.5 mg. The sprinkle capsules contain 1.5 mg granules which are to be dispersed onto a food vehicle prior to dosing.

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.

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.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Olaparib in people with Solid Tumours, run by AstraZeneca at 10 sites in 6 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 8 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 4 Apr 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 10 sites in France, South Korea, United Kingdom, Denmark, Germany and 1 more country. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Dose limiting toxicity [DLTs] (time frame: 28 days). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Apr 2025.
