PARP-Inhibitor Olaparib in children with solid tumors with HRR mutations

“A Phase 1, Open-label, Parallel Group Study to Investigate Olaparib Safety and Tolerability, Efficacy and Pharmacokinetics in Paediatric Patients with Solid Tumours (AZ Lynparza, D0816C00025)”

In this study, children and adolescents aged 6 months up to 18 years with relapsed or refractory non-CNS solid tumours are treated with Olaparib monotherapy. Olaparib specifically inhibits the enzyme PARP (Poly-[Adenosindiphosphat-Ribose]-Polymerase). The study therefore treats tumors whose genetic information show a deleterious or suspected deleterious germline or tumour HRR gene mutation and where the tumor has relapsed or progressed after standard therapy. Olaparib is taken orally over a 28-day cycle.

Inclusion of patients in Heidelberg has been possible since 28 May 2020.
