Combination of BTK Inhibitor Overcomes Drug-resistance in Refractory/Relapsed FLT3 Mutant AML

August 20, 2018 updated by: yuguopan, Nanfang Hospital of Southern Medical University

Combination of Brutons Tyrosine Kinase (BTK) Inhibitor Overcomes Drug-resistance in Refractory/Relapsed FLT3 Mutant Acute Myeloid Leukemia (AML)

Clinical efficacy of FLT3 inhibitors combining with chemotherapy is usually transient and followed by emergence of drug-resistance in FLT3-ITD mutant AML. BTK is reported to be a therapeutic target in this subtype leukemia. Our previous study showed inhibition of BTK onvercome drug-resistance to FLT3 inhibitors/chemotherapy in refractory/relapsed FLT3 mutant AML. In this prospective randomized controlled study, the efficacy and safety of combination of BTK inhibitor with chemotherapy with/without FLT3 inhibitor in refractory/relapsed FLT3 mutant AML are evaluated.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Clinical efficacy of FLT3 inhibitors combining with chemotherapy is usually transient and followed by emergence of drug-resistance in FLT3-ITD mutant acute myeloid leukemia (AML). How to overcome the resistance to FLT3 inhibitors or chemotherapy needs further study. Bruton's tyrosine kinase (BTK) is reported to be a therapeutic target in this subtype leukemia. Our previous study showed inhibition of BTK onvercome drug-resistance to FLT3 inhibitors/chemotherapy in refractory/relapsed FLT3 mutant AML. In this prospective randomized controlled study, we are going to inhibit BTK with BTK inhibitor ibrutinib in the patients with refractory/relapsed FLT3 mutant AML, and then test the enhancing effect and safety of combination of ibrutinib with chemotherapy with/without FLT3 inhibitor, to make sure inhibition of BTK overcomes drug-resistance in FLT3 mutation AML.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

14 years to 60 years (Child, Adult)

Accepts Healthy Volunteers

No
