Expanded Haploidentical Natural Killer Cells as Consolidation Strategy for Children/Young Adults With AML

This study is testing whether infusions of special immune cells called Natural Killer (NK) cells — donated by a half-matched family member — can help prevent leukemia from coming back in children and young adults with AML (a type of blood cancer). **You may be eligible if...** - You are a child or young adult with AML (intermediate or high risk) that is currently in remission - Your cancer responded well to treatment (no detectable cancer cells) - You are generally healthy enough to function independently (performance score ≥70) - You have a half-matched (haploidentical) family member who is willing to donate immune cells **You may NOT be eligible if...** - You have an active, uncontrolled infection - Your liver function is significantly impaired - You test positive for HIV - Your potential donor is pregnant or tests positive for HIV, hepatitis B, or hepatitis C Talk to your doctor to see if this trial is right for you.
