Phase I/II combination umbrella trial in progressive/relapsed/refractory pediatric low-grade glioma (pLGG) (EPILOGUE)
EU CTIS ID: 2024-516896-34-00
What this study is testing
The aim of this study is to identify promising single agent or combination-based treatment regimen(s) in a phase I/II multi-arm umbrella trial design with an intra-individual dose escalation concept in order to achieve the optimal dose in terms of safety and activity for each patient.

Who can take part
You may be able to join if
- Children and adolescents with progressive/relapsed/refractory pLGG and an indication for treatment, post first or maximum second line therapy (chemotherapy, targeted therapy, radiotherapy).
- Patients receiving steroids for tumor-associated symptoms must be on a stable dose (e.g., no initial/loading dose or no increase) for 14 days prior to start of treatment.
- Life expectancy > 3 months, sufficient general condition score (Lansky scale ≥ 70 or Karnofsky scale ≥ 70). Transient states like infections can be accepted, and also stable disabilities resulting from disease/surgery (hemiparesis etc.) can be accepted (they can be ignored for purposes of Lansky/Karnofsky assessments).
- Participant is able and willing to swallow and retain oral study medication.
- Adequate hematologic and organ function within 14 days before the first study treatment on Day 1 of Cycle 1, as defined by the following: - Hematology: Absolute granulocytes ≥ 1.0 × 109/L (unsupported) Platelets ≥ 100 × 109/L (transfusions allowed per institutional guidelines; last transfusion > 2 weeks prior to start of treatment, need to be stable) Hemoglobin ≥ 8 g/dl or ≥ 4.96 mmol/L (transfusions allowed per institutional guidelines; last transfusion > 2 weeks prior to start of treatment) - Biochemistry: Total bilirubin ≤ 1.5 x upper limit of normal (ULN) AST (SGOT) ≤ 3 x ULN ALT (SGPT) ≤ 3 x ULN Serum creatinine ≤ 1.5 x ULN. Patients with documented Gilbert’s Disease may be enrolled provided total bilirubin ≤ 2.0 × ULN and in the opinion of the Investigator, patient can safely participate in the study.
- ECG: normal QTc interval according to Bazett formula < 440 ms within 28 days prior to initiation of treatment.
You likely can't join if
- Patients with high-grade gliomas or tumors of unknown malignant potential including tumors with histone H3 mutation, isocitrate dehydrogenase (IDH) 1/2 mutation and/or cyclin-dependent kinase inhibitor (CDKN)2A/B deletion.
- Concomitant treatment with a strong cytochrome P450 2C8 (CYP2C8) or 3A4 (CYP3A4), 1A2 (CYP1A2) and CYP2D6 inhibitor/inducer, or treatment with medications that are substrates of breast cancer resistance protein (BCRP) with a narrow therapeutic index to tovorafenib, other than those allowed per Section 5.8.1 and Section 5.8.2, within 14 days before initiation of therapy. Medications that are substrates of CYP2C8 or CYP3A4 are allowed but should be used with caution.
- Traditional herbal medicines; these therapies are not fully studied and their use may result in unanticipated drug-drug interactions that may cause or confound the assessment of toxicity. As part of the enrollment/informed consent procedures, the patient will be counseled on the risk of interactions with other agents, and what to do if new medications need to be prescribed or if the patient is considering a new over-the-counter medicine or herbal product. For information on CYP inhibitors or inducers and P-glycoprotein inhibitors or inducers see Section 5.8.1 and Section 5.8.2.
- Patients with history of hypersensitivity to the investigational medicinal product or to any drug with similar chemical structure or to any excipient present in the pharmaceutical form (including benzamide) of the investigational medicinal product.
- Pregnant or lactating females.
- Patient is held in an institution by legal or official order.
