favorable outcomes reported for purged <strong>autologous</strong> bone <strong>marrow</strong> transplants is<br />

how much the purging contributed to the outcomes. This is stimulated by the<br />

occasional reports that unpurged <strong>marrow</strong> transplants have been associated with<br />

results comparable to purged transplants. However, recent evidence has been<br />

reported supporting the notion that purging is probably effective in reducing late<br />

relapses in AML.<br />

Thus, we propose to conduct a phase III r<strong>and</strong>omized trial<br />

comparing purged to unpurged stem cell transplants in patients with AML in<br />

remission.<br />

We propose to conduct this trial in patients with AML in first remission. There<br />

are compelling reasons to target this group of patients. One is that this group of<br />

patients has a cure rate of
