Eligibility Criteria
Inclusion Criteria:
- The participant completes either the Phase 3 pivotal study for ECH (Study TV48125-CNS-30056) or the Phase 3 pivotal study for CCH (Study TV48125-CNS-30057) without important protocol deviations related to participant safety and participant compliance.
- Prior to 15 June 2018, participants from the ECH study and the CCH study were enrolled. After 15 June 2018, only participants who participated in the ECH study (Study TV48125-CNS-30056) will be enrolled for active treatment.
In addition, participants who do not complete the pivotal efficacy studies, and participants who complete the pivotal efficacy studies but will not continue treatment during this long-term safety study, will be offered to enroll in this study for the purpose of evaluating ADAs, and safety (adverse events and concomitant medications) approximately 7.5 months after administration of the last dose of the IMP.
- Additional criteria apply, please contact the investigator for more information
Exclusion Criteria:
Any finding that, in the judgment of the investigator, is a clinically significant abnormality, including serum chemistry, hematology, coagulation, and urinalysis test values (abnormal tests may be repeated for confirmation)
