For currently enrolled patients not on hydroxyurea, the data monitoring committee (DMC) recommended that dosing with the study drug should be discontinued and that patients proceed to the end of study follow-up period. Approximately half of the patients enrolled in the study to date are not on concurrent hydroxyurea therapy.
The DMC also requested additional data and will reconvene when these are available. No specific safety issues were identified.
“The DMC carefully considered the available data in carrying out their review,” said Dr Seth Hetherington, senior vice president of clinical and regulatory affairs at Icagen. “We have notified the FDA of the recommendations of the DMC, and are implementing these recommendations beginning with notification of the investigators.”
