AC220 for Children With Relapsed/Refractory ALL or AML

A Phase I Study of AC220 for Children With Relapsed or Refractory ALL or AML

This is a phase I study of the investigational drug AC220 combined with cytarabine and etoposide in pediatric patients with relapsed acute lymphoblastic leukemia (ALL) and acute myelogenous leukemia (AML).

Study Overview

• Status: Completed
• Conditions: Lymphoblastic Leukemia, Acute, Childhood; Myelogenous Leukemia, Acute, Childhood
• Intervention / Treatment: Drug: AC220; Drug: Cytarabine; Drug: Etoposide; Drug: Methotrexate

Detailed Description

This is a study for pediatric patients with relapsed acute lymphoblastic leukemia (ALL) or acute myelogenous leukemia (AML). Some people diagnosed with leukemia have changes in a receptor located on the surface of white blood cells called FLT3. This is known as a FLT3 mutation. FLT3 plays an important role in the way cells grow and divide. In normal cells, the FLT3 receptor is switched off most of the time and only switches on when it gets a chemical signal from outside. But cells with the FLT3 mutation have the grow signal permanently switched on. This means leukemia cells with the FLT3 mutation are growing and dividing all the time. Doctors have found that people with leukemia cells that carry FLT3 mutations are less likely to go into remission with chemotherapy and have a higher risk of the leukemia coming back after treatment.

This is a study of an investigational drug called AC220. AC220 is considered investigational because it has not been approved in the United States by the Food and Drug Administration (FDA). AC220 is a drug which is able to "turn off" the FLT3 grow signal. AC220 will be given with cytarabine and etoposide to treat the relapsed leukemia. This is a phase I study, which means that the study is being done to find the highest dose of AC220 that can be given safely with the drugs cytarabine and etoposide to children and young adults.

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
The Dose of AC220 That is Safe and Biologically Active When Given in Sequential Combination With Ara-C/Etoposide	The incidence of dose limiting toxicity (DLT) will be measured. The maximum tolerated dose will be the highest study dose at which 1 or fewer of six patients experience DLT during cycle 1 of therapy. Plasma inhibitor activity (PIA) will be measured Pre-treatment and on Days 7, 14, 21 and 28 of Course 1. For the MTD to be considered biologically active, we will require that 7 of 9 patients achieve PIA of > 90% at 3 of 4 trough time points.	4 weeks from therapy start

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Disease Response	Possible outcomes are: Complete Remission (CR), Complete Remission without Platelet Recovery (CRp), complete response with incomplete hematologic recovery (CRi), Stable Disease, Progressive Disease, Induction Death, or Relapse	10 weeks
Count of Participants According to Inhibition of FLT3 Phosphorylation	PIA samples will be collected pre-treatment and on Days 7, 14, 21 and 28 of Course 1.	4 weeks from therapy start
