Study to Evaluate PK and Safety With Uproleselan Combined With Chemotherapy to Treat Chinese R/R AML Patients

Apollomics Inc.12 enrolled

Overview

This study will evaluate the safety and tolerability of uproleselan(GMI-1271), a specific E-selectin antagonist, and characterize the pharmacokinetic (PK) profile of uproleselan, in combination with chemotherapy to treat Chinese relapsed/refractory AML patients.

This study is a multicenter open-labelled study conducted in subjects with relapsed or refractory AML in China. The study includes the following phases: screening phase, induction phase, consolidation phase baseline, consolidation phase and follow-up period. Screening phase: This study will enroll 12 subjects, who are 18 to 60 years (inclusive) at the time of signing the Informed Consent Form (ICF), and with the diagnosis as relapsed or refractory AML. Screening is conducted 21 days to 2 days before administration, and signed ICF by the subject must be obtained before screening. Baseline period: The baseline period is 1 day before study drug administration. Induction treatment: During the induction phase, subjects will receive 8 consecutive days of uproleselan treatment and 5 consecutive days of MEC (mitoxantrone, etoposide, and cytarabine combined regimen) chemotherapy. Consolidation baseline: The baseline of the consolidation phase is 1 day before the treatment administration of the consolidation phase. Consolidation treatment: Subjects who met the criteria for consolidation treatment started the consolidation period at the 29th day of the previous treatment cycle at the earliest and the 65th day at the latest. Follow-up period: Each subject should complete the following follow-up stage: (1) Response evaluation to determine remission to the induction treatment (induction period); (2) EOT assessment after completing the last consolidation treatment cycle; (3) Death. Survival and long-term follow-up, including initiation of new anti-leukemia treatment (within 6 months after the last uproleselan/placebo administration), recurrence, HSCT and survival events, monthly (±14 days) for 2 years after the end of treatment, and afterwards quarterly (±14 days). The longest survival follow-up time is 3 years (calculated from the start of treatment).

Inclusion Criteria: 1. ≥18 years and ≤60 years in age 2. AML (including secondary AML) diagnosed as per WHO standards (2008). 3. For refractory AML, only cytarabine/daunorubicin(or Idarubicin) as can be applied repeatedly(maximal twice) as induction, no other chemotherapy are allowed to be applied Venatoclax /hypomethylation drug \[HMA\] can be used before and after chemotherapy. 1. For relapse AML, it must be the first or second relapse, and remain untreated. 2. Certain regimens (Venatoclax/HMA, Venetoclax/LDAC, HMA single agent) and FLT3 inhibitors, tyrosine kinase inhibitors, IDH1/IDH2 inhibitors or similar targeted inhibitors used alone are not considered cytotoxic chemotherapy are allowed. 4. ECOG performance status score is 0 to 2. 5. Stable hemodynamics and good organ function. Exclusion Criteria: 1.
