Design outcomes

Primary

MeasureTime frame
Main Objective: To evaluate the efficacy of DAY101 in pediatric patients aged 6 months to 25 years of age with a relapsed or progressive low-grade glioma (LGG) harboring a known activating BRAF alteration.;Secondary Objective: - To assess safety and tolerability of DAY101 - To determine the relationship between pharmacokinetics (PK) and drug effects, including efficacy and safety For the complete list of secondary objectives please refer to the protocol Section 2 "Study Objectives".;Primary end point(s): Overall Response Rate;Timepoint(s) of evaluation of this end point: End of Cycle 3, end of Cycle 6, and ever 3 cycles thereafter. Please see Appendix A of the protocol.

Secondary

MeasureTime frame
Secondary end point(s): - Type, frequency, and severity of AEs and laboratory abnormalities - Pharmacokinetic profile of DAY101 (e.g., area under the concentration-time curve [AUC], Cmin, etc.) - time following initiation of DAY101 to progression or death in patients treated with DAY101 - length of response in patients with best overall confirmed response of CR or PR - time to first response following initiation of DAY101 in patients with best overall confirmed response of CR or PR Please see Table 6 in protocol for further information.;Timepoint(s) of evaluation of this end point: AEs: From the start of treatment with DAY101 until 30 days after the last dose. PK profile (blood sampling): C1D1, C1D15, C2D1, C41, Every 3rd cycle, At the time of toxicity, and/or at time of surgery, if clinically indicated. Change from QT interval, baseline PR interval, baseline QRS interval, baseline heart rate, Please see Appendix A of the protocol for further details.
