Acute Myeloblastic Leukaemia

This Phase I/IIa clinical study is testing an experimental treatment called GYA01 (CART84) for people with acute myeloid leukemia (AML) or T-cell acute lymphoblastic leukemia (T-ALL) whose disease has come back after treatment (relapsed) or did not respond to treatment (refractory). GYA01 (CART84) is a type of CAR T-cell therapy. In this approach, a participant's own T cells (a type of immune cell) are collected and changed in a laboratory to help them better recognize and attack leukemia cells. The modified cells GYA01 (CART84) are then given back to the participant through an infusion into a vein. The study is being done to: Find a dose that can be given safely (Phase I) by treating small groups of participants with increasing dose levels and carefully monitoring side effects. Look for early signs that GYA01 (CART84) may help control AML or T-ALL (Phase IIa). Participants will be closely monitored for side effects and for changes in their leukemia after the infusion, and followed over time to understand safety and possible benefit.

This study aims to examine the effect of mandala coloring activity, administered before intrathecal chemotherapy treatment in children with leukemia, on pre-procedure anxiety and fear in children. The main question this study aims to answer is: Does mandala coloring administered before intrathecal chemotherapy treatment reduce pre-procedure anxiety and fear in children with leukemia? Descriptive demographic data will be collected from the children who will be given mandalas. Data will be collected using an Anxiety Scale and a Fear Scale.
