Complete Cytogenetic Response at 6 and 12 Months (Phase II)
13 Participants

PRIMARY outcome

Timeframe: At 6 and 12 months during phase II

Population: The reason why remaining outcomes can not be reported is due to loss of the study data. Results published 13 years ago were only partial at the time despite having overlapping timeframes with other outcomes. Efforts made since to locate original data to report remaining outcomes were unsuccessful due to early termination and staff turnover.
