Brief Summary:
The purpose of this study is to explore safety, tolerability, including the maximum tolerated dose, and antitumor activity of NMS-03592088 in adult patients with relapsed or refractory Acute Myeloid Leukemia (AML) or Chronic Myelomonocytic Leukemia (CMML).

Condition or disease Intervention/treatment Phase
Acute Myeloid Leukemia (AML) Chronic Myelomonocytic Leukemia (CMML) Drug: NMS-03592088 Phase 1 Phase 2

Detailed Description:
This is an open-label Phase I/II, first-in-human, multi-center clinical study in sequential cohorts of patients with relapsed or refractory AML or CMML who have exhausted standard treatment options or for whom standard therapy is considered unsuitable. The study is designed to characterize the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD) and to explore anticancer activity of NMS-03592088, a FLT3 (Fms-like tyrosine kinase 3), KIT (v-kit Hardy-Zuckerman 4 feline sarcoma viral oncogene homolog ) and CSF1R (Colony stimulating factor-1 receptor) inhibitor. The study drug will be administered orally once daily for 21 consecutive days followed by 7 days of rest (each cycle is 28 days). The study will be conducted in two parts: a Phase I dose escalation and dose expansion part including patients with AML and CMML and a single-stage Phase II exploratory study comprising two parallel cohorts of selected patients that are more likely to respond to the drug: a cohort of AML FLT3 mutated patients and a second one of patients with CMML. Patients previously treated with FLT3 inhibitors are allowed to participate.

Arm Intervention/treatment
Experimental: Dose Escalation and Expansion (Phase I)
Dose escalation will be applied until one patient experiences first cycle DLT (Dose Limiting Toxicity) or 2 patients at any dose level experience non-DLT NCI CTCAE Grade ≥2 drug-related toxicity during the first cycle. Once the Maximum Tolerated Dose (MTD) is identified, a maximum of 10 additional patients will be enrolled (dose expansion).

NMS-03592088 will be administered orally once daily for 21 consecutive days of each treatment cycle. A treatment cycle will comprise 21 days of NMS-03592088 administration (Day 1 to 21) followed by 7 days of rest for a total of 28 days (4 weeks) period.

Experimental: CMML (Phase II)
Cohort of patients with CMML. NMS-03592088 will be administered at the recommended Phase II dose (RP2D) defined in Phase I part.
Drug: NMS-03592088
NMS-03592088 will be administered orally once daily for 21 consecutive days of each treatment cycle. A treatment cycle will comprise 21 days of NMS-03592088 administration (Day 1 to 21) followed by 7 days of rest for a total of 28 days (4 weeks) period.




Primary Outcome Measures :
  1. Phase I - Number of Participants with first-cycle dose limiting toxicities (DLTs) [ Time Frame: Between the date of the first dose administration in Cycle 1 and the date of the first dose administration in Cycle 2 which is expected to be 28 days or up to 42 days in case of dose delay. ]

    DLT is defined as any grade ≥3 non-hematologic toxicity occurring in the first cycle of treatment and considered at least possibly related to NMS-03592088, with the exception of:

    • anorexia, fatigue;
    • grade 3 infection and fever with neutropenia;
    • grade 3 diarrhea or nausea that did not require tube-feeding or total parenteral nutrition, or diarrhea that could be managed to grade 2 or better with standard drugs.

    Hematological adverse events will not be considered as DLTs. DLTs will be classified according to CTCAE version 5.0.


  2. Phase II - FLT3 mutated AML - Overall Response Rate (ORR) [ Time Frame: From first dose of study drug to End of Treatment (up to 9 months of treatment) ]
    Percentage of Participants with Complete Remission (CR) + Incomplete Hematologic Recovery (CRi) + Morphologic Leukemia-free State (MLFS) + Partial Remission (PR). Responses will be assessed according to the ELN guidelines for Acute Myeloid Leukemia (AML).

  3. Phase II - CMML - Overall Response Rate (ORR) [ Time Frame: From first dose of study drug to End of Treatment (up to 9 months of treatment) ]
    Percentage of Participants with Complete Remission + Complete Cytogenetic Remission + Partial Remission + Marrow Response + Clinical benefit). Responses will be assessed according to the WHO Criteria for Chronic Myelomonocytic Leukemia (CMML).


Secondary Outcome Measures :
  1. Number of participants with Adverse Events (AEs) [ Time Frame: Adverse Events: From the Informed Consent signature to 28 days after the last on-study treatment administration. ]
    Safety will be assessed by AEs, which included abnormalities identified during a medical test (e.g. laboratory tests, vital signs, electrocardiogram, etc.) if the abnormality induces clinical signs or symptoms, needs active intervention, interruption or discontinuation of the study drug or is medically significant. A treatment-emergent AE is defined as abn AE observed after starting administration of the study drug up to 28 days after last dose of study medication intake. AEs will be coded with the Medical Dictionary for Regulatory Activities (MedDRA) and graded according to the The National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) version 5.0

  2. Overall Survival (OS) [ Time Frame: From first dose of study drug up to data cut-off (approximately 18 months) ]
    The time from the date of the first dose of study drug until the date of death for any cause. For a participant not known to have died by the end of study follow-up, OS will be censored at the date of the last contact OS will be calculated using Kaplan-Meier estimates.

  3. Time to Response (TTR) [ Time Frame: From first dose of study drug up to data cut-off (approximately 18 months) ]
    TTR is defined as the time from the first dose of study drug until the date of first response. TTR will be as evaluated for participants who achieved response during treatment, as defined for AML and CMML populations

  4. Duration of Response [ Time Frame: From date of first remission up to data cut-off (approximately 18 months) ]
    Duration of response was defined as the time from the date of either first CRc or PR until the date of documented relapse of any type for participants who achieved CRc or PR. Participants who died without report of relapse will be considered non-events and censored at their last relapse-free disease assessment date. Other participants who will not relapse on study will be considered non-events and censored at the last relapse-free assessment date. Duration of response will be calculated using Kaplan-Meier method and therefore data will be estimated.

  5. Relapse-Free Survival (RFS) [ Time Frame: From first dose of study drug up to data cut-off (approximately 18 months) ]
    Duration of response is defined as the time from the date of first dose of study drug until the date of documented relapse/ Progression Disease of any type, as defined for AML and CMML populations. Participants who died without report of relapse will be considered non-events and censored at their last relapse-free disease assessment date. Other participants who will not relapse on study will be considered non-events and censored at the last relapse-free assessment date. Duration of response will be calculated using Kaplan-Meier method and therefore data will be estimated.

  6. Composite Complete Remission Rate (CRc; CR+CRi+MLFS) [AML population only] [ Time Frame: From first dose of study drug to End of Treatment (up to 9 months of treatment) ]
