MAX-40279 in Subjects With Acute Myelogenous Leukemia (AML)

A Phase I Trial of MAX-40279 Given Orally to Subjects With Acute Myelogenous Leukemia (AML)

This is a dose-escalation phase I trial to evaluate the safety and tolerability of MAX-40279 in subjects with acute myelogenous leukemia(AML).

Study Overview

• Status: Recruiting
• Conditions: Acute Myelogenous Leukemia (AML)
• Intervention / Treatment: Drug: MAX-40279

Detailed Description

The class III receptor tyrosine kinase FMS-related tyrosine kinase 3 (FLT3), is mutated and activated in about 30% of adult patients with AML. The mutations involve either an internal tandem duplication (ITD) (in about 25% of AML patients) or a point mutation in the tyrosine kinase domain (TKD) (in about 7% of patients). Patients with mutations in FLT3, particularly those with ITD mutations, have a worse prognosis, with lower rate of complete remission, and lower overall survival . Thus, inhibition of activated FLT3 kinase by a pharmacologic agent is an attractive therapeutic strategy in AML.

The aberrant of fibroblast growth factor receptor (FGFR) might be a major reason fot resistance to targeted therapies, and FGFR inhibitors significantly suppress leukemia development in vivo.

MAX-40279 is a dual inhibitor of FLT3 and FGFR. Our goal is to develpe this uqiue dual inhibitor to be a more effective and wider use for AML treatment than the current known FLT3 inhibitors.

Description

Inclusion Criteria:

6. In the absence of rapidly progressing disease clearly documented by the investigator, the interval from prior treatment to time of MAX-40279 administration will be at least 2 weeks (14 days) for prior cytotoxic agents or at least 5 half-lives for prior noncytotoxic agents, including immunosuppressive therapy post HSCT

7. Acceptable liver function defined below:

   • Total bilirubin ≤ 1.5 times upper limit of normal range (ULN)
   • Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) ≤ 3 times ULN;

8. Acceptable renal function defined below:

   • Serum creatinine ≤ 1.5 times ULN or calculated creatinine clearance (by the Cockcroft-Gault formula) ≥ 60 mL/min

A highly effective method of contraception is defined as one that results in a low failure rate, i.e., less than 1% per year, when used consistently and correctly

8. Medical history of difficulty swallowing, malabsorption or other chronic gastrointestinal disease, or conditions that may hamper compliance and/or absorption of the tested product
9. Participation in an investigational drug or device trial within 4 weeks prior to the trial entry
10. Known infection with human immunodeficiency virus (HIV), hepatitis B, or hepatitis C
11. Recent venous thrombosis (including deep vein thrombosis or pulmonary embolism within 1 year of study)
12. History of upper gastrointestinal hemorrhage, peptic ulcer disease, or bleeding diathesis
