Brief summary
The goal of this prospective, observational study VIOLETA is to collect real-world data on vorasidenib treatment in a broad patient population. Though vorasidenib can be administered from 12 years old, VIOLETA focuses on adult patients with IDH1- or IDH2-mutant WHO grade 2 glioma who receive vorasidenib following surgery according to the current SmPC. Thus, VIOLETA will evaluate for the first-time treatment with vorasidenib in German clinical routine. To gain knowledge about how vorasidenib treatment affects patients' well-being, the primary objective of the study is to assess patients' quality of life. Further patient-relevant endpoints addressed by this study will include seizure burden, PFS, Objective Response Rate (ORR), TTNI, safety as well as factors affecting treatment decision making.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Evaluate Quality of Life (QoL) by the Functional Assessment of Cancer Therapy - Brain (FACT-Br) questionnaire over the course of treatment | baseline, up to 72 months | Evaluate QoL by the FACT-Br questionnaire over the course of treatment. Change from baseline in the FACT-Br total score over time. The FACT-Br total score ranges from 0 to 200, with higher scores indicating better quality of life. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Evaluate Quality of Life (QoL) by using the Functional Assessment of Cancer Therapy - Brain (FACT-Br) questionnaire at start and during course of vorasidenib treatment | baseline, up to 72 months | Evaluate QoL by using the FACT-Br questionnaire at start and during course of vorasidenib treatment. Change from baseline over time for all other scales of the FACT-Br. For all scales, the higher the score the better quality of life. |
| Assess seizure activity and severity at baseline and during treatment: Proportion of patients with baseline seizure activity | baseline, up to 72 months | Proportion of patients with baseline seizure activity is defined as at least 1 seizure in the previous 30 days prior to vorasidenib treatment start |
| Assess seizure activity and severity at baseline and during treatment: event rate of seizures | baseline, up to 72 months | Exposure adjusted event rate of seizures according to patient-reported outcome (patient diary) |
| Assess seizure activity and severity at baseline and during treatment: event rate of seizures with loss of consciousness | baseline, up to 72 months | Exposure adjusted event rate of seizures with loss of consciousness according to PRO (patient diary) |
| Assess seizure activity and severity at baseline and during treatment: incidence rate of seizures | baseline, up to 72 months | Exposure adjusted incidence rate of seizures according to patient-recorded outcome |
| Assess seizure activity and severity at baseline and during treatment: incidence rate of seizures with loss of consciousness | baseline, up to 72 months | Exposure adjusted incidence rate of seizures according to patient-reported outcome |
| Assess seizure activity and severity at baseline and during treatment: Change from baseline of seizures | max. 72 months; from patient-specific study start to end of study (during vorasidenib treatment and follow-up) | Change from baseline of seizures reported by the patients during course of treatment |
| Assess effectiveness in routine treatment: Progression-free survival | baseline, up to 72 months | PFS ist defined as time interval measured from the day of first vorasidenib administration to first progression or death, whichever comes first. Patients without tumor progression or death at the time of analysis will be censored at their date of last contact. |
| Assess effectiveness in routine treatment: Overall Survival (OS) | baseline, up to 72 months | OS is defined as the time interval measured form the day of first vorasidenib administration to time of death from any cause. Time to last contact will be used if a patient has no documented date of death and OS for the patient will be considered censored. |
| Assess effectiveness in routine treatment: Objective response rate (ORR) | max. 72 months; from patient-specific study start to end of study (during vorasidenib treatment and follow-up) | ORR is defined as the proportion of patients achieving Complete Response (CR), Partial Response (PR), or Minor Response (MR) as best response. |
| Assess effectiveness in routine treatment: Disease Control Rate (DCR) | baseline, up to 72 months | DCR is defined as proportion of patients with Complete Response, Partial Response, Minor Response or Stable Disease as best response. |
| Assess effectiveness in routine treatment: Best response | baseline, up to 72 months | Best response is defined as Complete Response (CR), Partial Response (PR), Minor Response (MR), Stable Disease (SD), or Progressive Disease (PD)) |
| Assess effectiveness in routine treatment: Time to next intervention (TTNI) | baseline, up to 72 months | Time to next intervention is defined as time from first administration of vorasidenib until initiation of next intervention (i.e., subsequent antineoplastic treatment, surgery, chemotherapy or radiotherapy) or death, whichever comes first. |
| Assess drug safety: Incidence of (serious) adverse events ((S)AEs) | Baseline up to 30 days after vorasidenib treatment | Incidence of (serious) AEs ((S)AEs) as characterized by type, frequency, severity and seriousness. |

| Assess drug safety: Incidence of seizures reported as treatment-emergent adverse events (TEAEs) | Baseline up to 30 days after vorasidenib treatment | Treatment-emergent adverse events (TEAE) are adverse events that were not present before medical treatment, or a pre-existing event that worsens in intensity or frequency during vorasidenib treatment and the following 30 days. |
