Brief Summary:
This is an open-label, multi-centre, single arm, interventional study to describe the steady-state PK, safety, and efficacy of mexiletine in paediatric patients (6 to \<18 years of age) with myotonic disorders.
Detailed Description:
This is an open-label, multi-centre, single arm, interventional study to describe the steady-state PK, safety, and efficacy of mexiletine in paediatric patients (6 to \<18 years of age) with myotonic disorders.
Patients who meet the eligibility criteria will be enrolled stepwise, sequentially in 2 cohorts by age groups.
Cohort 1 - Adolescents aged 12 to \<18 years, will be enrolled first. If no safety concerns are observed (based on data evaluation by the Data Safety Monitoring Board \[DSMB\]), and the dose for the age group 6 to \<12 years is confirmed by PK model, enrolment for Cohort 2 will begin.
Cohort 2 - Children aged 6 to \<12 years, will be enrolled. The overall treatment duration for each cohort will be approximately 56 days (8 weeks): a dose titration phase of 4 weeks and the maintenance phase of 4 weeks. The overall study duration would be approximately 22 months.
Dose titration phase: In this phase, patients will receive mexiletine starting at an age appropriate dose (as evaluated by the investigator and based on body weight) at a frequency of once a day. Dose will be up-titrated every 14 days based on tolerability of mexiletine up to a maximum of three-times a day as assessed by investigator.
Maintenance phase: During the maintenance phase, patients will continue to receive mexiletine at the best-tolerated dose from the titration phase for further 4 weeks. Following completion, all participants will be offered follow-up in PIP Study 7 (MEX-NM-303) (EudraCT: 2019-003758-97).
