LGG Cohort: PROMIS Parent Proxy Global Health 7+2 Scores- Pain Score

Study of Efficacy and Safety of Dabrafenib in Combination With Trametinib in Pediatric Patients With BRAF V600 Mutation Positive LGG or Relapsed or Refractory HGG Tumors · Source last updated 2023-12-13

Results reported by the registry submitting party. Population, time horizon, units and missing values must be read together.

Measure: MEAN
Unit: Score on a Scale
Interval / dispersion: Standard Deviation
Time frame: Baseline, and Day 1 of Week 5, 8, 16, 24, 32, 49, 48 and 56, and thereafter every 16 weeks until end of treatment (EOT), EOT, and every 16 weeks in the post-treatment efficacy follow-up phase until disease progression (assessed up to 4.6 years)

What was measured

The PROMIS Parent Proxy Global Health 7+2 was used to evaluate the quality of life of participants. The questionnaire included 1 item measuring the pain of the participants. Pain item used a 5-level Likert scale with 1= never and 5= almost always, higher scores indicate worsening pain. Raw scores were then converted into T-scores, standardized with a mean of 50 and a standard deviation of 10. Higher T-scores indicated more severe pain experiences. Participants who discontinued treatment for reasons other than disease progression entered the post-treatment efficacy follow-up phase, where the PROMIS Parent Proxy Global 7+2 Health questionnaire was performed every 16 weeks until disease progression, withdrawal of consent by patient or a parental/legal guardian, or lost to follow-up.

Analysis population: All participants on the LGG cohort to whom study treatment had been assigned by randomization (regardless of whether or not treatment was administered) and contributed to this analysis. According to the intent to treat principle, patients were analyzed according to the treatment they had been assigned to during the randomization procedure. Number analyzed indicated number of participants with available data for this outcome measure at the specified timepoints.

Groups in this outcome

LGG Cohort: Dabrafenib and Trametinib

Participants in the LGG cohort randomized to receive dabrafenib (orally, twice daily and dosed based on weight and age) in combination with trametinib (orally, once daily in combination with the first daily dose of dabrafenib and was dosed based on weight)

LGG Cohort: Carboplatin and Vincristine

Participants in the LGG cohort randomized to receive active comparator chemotherapy (carboplatin and vincristine). Participants received one course of induction (10 weeks of chemotherapy with 2 weeks of rest), followed by 8 cycles of maintenance chemotherapy. Participants were allowed to crossover to dabrafenib and trametinib after centrally confirmed and RANO-defined disease progression.

Group identifiers and denominators belong to this outcome only. They may differ in another outcome or in safety reporting.
