  • Relapse Free Survival [ Time Frame: Through study completion, an average of 6 months. ]
    Defined as the time the criteria for remission (CR or CRi) are first met until there is evidence of patient relapse, regardless of whether the patient is still taking study drug.
  • Clinical Benefit Rate [ Time Frame: 4 months after LPI ]

Descriptive Information
Brief Title  ICMJE A Dose Optimisation Study of ASLAN003 in Acute Myeloid Leukemia
Official Title  ICMJE A Phase IIA Dose Optimisation Study of ASLAN003 in Acute Myeloid Leukemia
Brief Summary ASLAN003-003 is a multi-center, Phase IIA study to evalute the efficacy of ASLAN003 in AML patients who are ineligible for standard treatment with an expansion cohort in relapsed/refractory patients, and to determine the appropriate dose of ASLAN003 in combination with azacitidine in older (more than or equal to 60 years) AML patients who have exhausted any approved and available treatment options.
Detailed Description

ASLAN003-003 is a multi-center, Phase IIA study to determine the optimum dose of ASLAN003 based on the safety, efficacy, and tolerability of varying doses of ASLAN003 (100 mg QD, 200 mg QD, 100 mg BID, and possibly 200 mg BID) administered to AML subjects daily for a continuous 28-day treatment cycle until disease relapse, disease progression, unacceptable toxicity, or withdrawal of consent.

The study has 2 parts and plans to enroll a total of 44 to 56 patients with 18 to 24 patients in Part 1 and 26 to 32 patients in Part 2 (comprising Parts 2A and 2B). The Overall Complete Remission Rate will be evaluated in AML patients not eligible for standard treatment (Part 1) and in relapsed and refractory AML patients (Part 2A) using the optimum dose of ASLAN003 established in Part 1 of the study. In Part 2B of the study, the appropriate dose of ASLAN003 in combination with azacitidine in older (more than or equal to 60 years) AML patients who have exhausted any approved and available treatment options will be determined.
