Observational iOMEDICO AG · NCT07240662

This study will try vorasidenib in adults with IDH1- or IDH2-mutant WHO grade 2 diffuse glioma after surgery to see if it affects quality of life and clinical outcomes.

What this trial studies

VIOLETA is a prospective, observational real-world study collecting data on adults treated with vorasidenib for IDH‑mutant WHO grade 2 diffuse glioma in routine German clinical practice. Eligible patients have undergone surgery, do not need immediate radiotherapy or chemotherapy, and are started on vorasidenib according to the current SmPC; enrollment is allowed up to six weeks after the first dose provided treatment is ongoing. The study focuses on patient-reported outcomes in German, with primary emphasis on quality of life and secondary endpoints including seizure burden, progression-free survival, objective response rate, time to next intervention, and safety. Data will be collected from the treating center (NCT Heidelberg) following local practice patterns to describe how vorasidenib is used and tolerated outside of interventional trials.

Who should consider this trial

Good fit: Adults (≥18) with WHO grade 2 astrocytoma or oligodendroglioma carrying an IDH1 or IDH2 mutation who have had surgery, do not require immediate radiotherapy or chemotherapy, and are starting vorasidenib per the product label are the ideal candidates.

Not a fit: Patients who need immediate radiotherapy or chemotherapy, who are enrolled in interventional trials, who cannot provide informed consent, or who have contraindications per the vorasidenib label are unlikely to be eligible or benefit from participation.

Why it matters

Potential benefit: If successful, vorasidenib could help maintain quality of life and delay disease progression in adults with IDH‑mutant WHO grade 2 glioma.

How similar studies have performed: Early-phase clinical studies of vorasidenib have shown promising activity in IDH‑mutant gliomas, but larger and real-world data remain limited.
