Study Details

Study Description

Brief Summary

This is a Phase I, open-label, non-randomized, multicenter study to evaluate the safety, pharmacokinetics and preliminary efficacy of HMPL-523 in combination with Azacitidine in previously untreated elderly patients with AML who are not eligible for standard induction therapy.

Condition or Disease Intervention/Treatment Phase
Phase 1

Detailed Description

There are two stages in this study: a dose-escalation stage (stage 1) and a dose-expansion stage (stage 2).

Dose-escalation stage (stage 1):

The conventional 3+3 design (3 patients per dose cohort, with the potential to add additional 3 patients to the same cohort to further evaluate toxicity) will be applied for dose escalation and maximum tolerated dosage determination. Approximately 12 to 18 dose limited toxicities evaluable patients will be enrolled. A dose of HMPL-523 up to 800mg will be taken orally once daily continuously through a 28-day Cycle of study treatment. Azacitidine will be administered subcutaneously, beginning on Day 1 through Day 7 of each Cycle.

Dose-expansion stage (stage 2):

This phase is to further evaluate the safety, pharmacokinetics and preliminary efficacy of HMPL-523 in combination with Azacitidine in approximately 28 previously untreated elderly patients with AML. Patients will receive HMPL-523 in combination with Azacitidine in a 28-day cycle continuously until disease progression/relapse, death, or intolerable toxicity, whichever comes first.

  • Outcome Measures

    Primary Outcome Measures

    1. Adverse Event (AE) monitoring of HMPL-523 in combination with azacitidine [Measured from the first dose to within 30 days after the last dose.]

      AE monitoring will be assessed by evaluation of study drug exposure, AEs , serious AEs, all deaths, as well as laboratory determinations and vital sign parameters.

    2. Overall response rate (ORR) [Measured up to 1 year after the last subject has enrolled or all the subjects have finished their last EFS follow up, whichever comes first.]

      Overall response rate will be defined as the proportion of subjects who achieve a complete remission (CR), complete remission incomplete (CRi), Morphologic leukemia-free state (MLFS), or partial remission(PR) per 2017 European Leukemia Net (ELN) recommendations

    Secondary Outcome Measures

    1. Maximum plasma concentration (Cmax) of HMPL-523 [Measured on the cycle 1 day 7, cycle 1 day 8, cycle 1 day 28 and cycle 2 day 1.]

      Maximum concentration, occurring at Tmax.

    2. The time to Cmax (peak time, Tmax) of HMPL-523 [Measured on the cycle 1 day 7, cycle 1 day 8, cycle 1 day 28 and cycle 2 day 1.]

      The time at which maximum plasma concentration (Cmax) is observed.

    3. The area under the plasma concentration-time curve (AUC) from 0 to the time of the last measurable concentration (AUCt) of HMPL-523 [Measured on the cycle 1 day 7, cycle 1 day 8, cycle 1 day 28 and cycle 2 day 1.]

      The area under the plasma concentration-time curve (AUC) from 0 to the time of the last measurable concentration.

    4. Half-life (t1/2) of HMPL-523 [Measured on the cycle 1 day 7, cycle 1 day 8, cycle 1 day 28 and cycle 2 day 1.]

      The time required for the concentration of the drug to reach half of its original value.

    5. Clearance (CL) of Azacitidine [Measured on the cycle 1 day 7 and Cycle 1 day 8.]

      Clearance is defined as the rate at which drug is cleared from the blood.

    6. The area under the plasma concentration-time curve (AUC) from 0 to the time of the last measurable concentration (AUCt) of Azacitidine [Measured on the cycle 1 day 7 and Cycle 1 day 8.]

      The area under the plasma concentration-time curve (AUC) from 0 to the time of the last measurable concentration.

    7. Half-life (t1/2) of Azacitidine [Measured on the cycle 1 day 7 and Cycle 1 day 8.]

      The time required for the concentration of the drug to reach half of its original value.

    8. Steady-state concentration(Css) of Azacitidine [Measured on the cycle 1 day 7 and Cycle 1 day 8.]

      The average concentration of drug at steady state

    9. Complete Remission Rate of Minimal Residual Disease (MRD) Negativity (CR MRD- rate) [Measured up to 1 year after the last subject has enrolled or all the subjects have finished their last EFS follow up, whichever comes first.]

      CR MRD- rate will be defined as the proportion of subjects who achieve a CR and has a negative RT-qPCR or MFC at the same time.

    10. Event Free Survival (EFS) [Measured up to 1 year after the last subject has enrolled or all the subjects have finished their last EFS follow up, whichever comes first.]

      EFS will be defined as the number of days from the date of first dose to the date of earliest recurrence or PD or death.

    11. Disease-free Survival (DFS) [Measured up to 1 year after the last subject has enrolled or all the subjects have finished their last EFS follow up, whichever comes first.]

      DFS will be defined as the number of days from the date of composite complete response (CR + CRi) to the date of earliest recurrence or death.

    12. Overall Survival (OS) [Measured up to 1 year after the last subject has enrolled or all the subjects have finished their last EFS follow up, whichever comes first.]

      OS will be defined as the number of days from the date of enrollment to the date of death.

    13. Cumulative incidence of relapse (CIR) [Measured up to 1 year after the last subject has enrolled or all the subjects have finished their last EFS follow up, whichever comes first.]

      CIR will be defined as the cumulative proportion of subjects who has relapsed after achieving a composite complete response (CR + CRi).
