PRIMARY outcome

Timeframe: up to 5 years

Population: All patients enrolled into core study and who consented to participate in extension contributed to the pool of data on long term safety follow-up. Analyses included all patients who received at least 1 dose of ICL670 in the core/extension study, that is, analyses also included ICL670 patients from the core group who did not continue into extension.

Adverse events results are based on preferred terms with at least 7% of participants in any group.
