1 Paediatric patients with pathologically confirmed relapsed or refractory non-CNS solid tumours (excluding lymphoid malignancies), with a HRR deficiency, and for whom there are no standard treatment options. Eligible patients may include but not be limited to those with osteosarcoma, rhabdomyosarcoma, non-rhabdomyosarcoma soft tissue sarcoma, Ewing Sarcoma and neuroblastoma.
(a) Any number of prior treatment regimens allowed.
(b) A select group of first-line patients may be considered on a case by case basis to be eligible for screening and enrolment. These patients will be enrolled based on Investigator assessment after discussion with the sponsor as patients for whom no curative standard of care treatment options exist or such therapies are not tolerable.
2. An FFPE tumour sample from the primary cancer (all patients) and blood sample (patients =2 years old) suitable for central HRR testing must be provided for each patient. The blood and tumour samples will be collected for central assessment of HRR status using a central laboratory. Patients with a known HRR deficiency (based on local testing) are not required to wait for the results of the central test to proceed with the main part of the study, assuming all other eligibility criteria are met. The blood (from patients with a known HRR deficiency) and tumour samples for central confirmation should be shipped to the central laboratory following enrolment; patients with unknown HRR deficiency status will have their blood samples sent for central confirmation prior to enrolment.
(a) A FFPE tumour tissue block is required, but if not available, tissue sections are accepted. The tumour specimen submitted should be of sufficient quantity to allow for HRR mutation status and other exploratory biomarker analyses.
(b) Patients who don’t have an archival tumour sample may be allowed to provide a newly biopsied FFPE tumour tissue sample provided the sample is taken as part of routine clinical practice. The most recent sample available should be provided. Tumour lesions used for newly acquired biopsies should not be the same lesions used as RECIST v1.1 or INRC target lesions, unless there are no other lesions suitable for biopsy (re-assessment after biopsy may be required).
3. Lansky scale =50 for patients =16 years of age; or Karnofsky score =50 for patients >16 years of age (see Appendix F).
4. For all non-neuroblastoma tumours, patients must have at least 1 lesion (measurable and/or non-measurable), not previously irradiated, that can be accurately assessed at baseline and is suitable for repeated assessment using RECIST v1.1. Lesions in a previously irradiated field can be used as measurable disease, provided that there has been demonstrated progression in the lesion and the lesion measures at least 20 mm.
5. For neuroblastoma tumours, patients must have:
(a) Radiographical assessable disease with at least 1 lesion (measurable and/or non-measurable) that can be accurately assessed at baseline and is suitable for repeated assessment using International Neuroblastoma Response Criteria (INRC); OR,
(b) Disease evidenced by uptake of meta-iodobenzylguanidine- (MIBG) or fluorodeoxyglucose positron emission tomography (FDG-PET) scans.
6. Patients must have normal organ and bone marrow function measured within 28 days prior to administration of study treatment as defined in the protocol.
Please refer to the protocol for full inclusion criteria.
Are the trial subjects under 18? yes
1. Patients with MDS/AML or with features suggestive of MDS/AML.
2. Patients unable to swallow orally administered medication and patients with gastrointestinal disorders likely to interfere with absorption of the study drug.
3. Any unresolved toxicity NCI CTCAE Grade =2 from previous anticancer therapy with the exception of alopecia, vitiligo, lymphopenia, and the laboratory values defined in the inclusion criterion. Patients with a toxicity not reasonably expected to be exacerbated by study treatment (eg, hearing loss, gastrostomy tube) may be included after consultation with the Study Physician.
4. Patients considered a poor medical risk due to a serious, uncontrolled medical disorder, non-malignant systemic disease or active, uncontrolled infection. Examples include, but are not limited to, uncontrolled ventricular arrhythmia, recent (within 3 months) myocardial infarction, uncontrolled major seizure disorder, unstable spinal cord compression, superior vena cava syndrome, extensive interstitial bilateral lung disease on High Resolution Computed Tomography scan, ongoing or active infection, symptomatic congestive heart failure, cardiac arrhythmia, interstitial lung disease, or any psychiatric illness or social situations that would limit compliance with study requirements, substantially increase the risk of incurring AEs from IP, or compromise the ability of the patient to give written informed assent.
5. History of other primary malignancy unless curatively treated with no evidence of disease for =5 years. Non-invasive malignancies such as adequately treated non-melanoma skin cancer or in situ carcinomas that have been adequately treated may be permitted after detailed discussion with the Study Physician.
6. Patients with CNS disease meeting the following criteria:
(a) Symptomatic uncontrolled brain metastases at baseline. A scan to confirm the absence of brain metastases is not required. Patients with stable brain metastases are allowed as long as corticosteroids are not required for management of symptoms or progression.
(b) Patients with spinal cord compression unless considered to have received definitive treatment for this and evidence of clinically stable disease for 28 days.
7. History of active primary immunodeficiency or immunocompromised patients, eg, patients who are known to be serologically positive for human immunodeficiency virus (HIV).
8. Patients with known active hepatitis (ie, Hepatitis B or C).
(a) Active hepatitis B virus (HBV) is defined by a known positive HBV surface antigen (HBsAg) result. Patients with a past or resolved HBV infection (defined as the presence of hepatitis B core antibody and absence of HBsAg) are eligible.
(b) Patients positive for hepatitis C virus (HCV) antibody are eligible only if polymerase chain reaction is negative for HCV ribonucleic acid.
9 Resting ECG indicating uncontrolled, potentially reversible cardiac conditions, as judged by the Investigator (eg, unstable ischemia, uncontrolled symptomatic arrhythmia, congestive heart failure, corrected QT interval (QTc) prolongation >500 ms, electrolyte disturbances, etc.), or patients with congenital long QT syndrome.
10Any condition that, in the opinion of the Investigator, would interfere with evaluation of the study treatment or interpretation of patient safety or study results.
Please refer to the protocol for full exclusion criteria.
