Outcome Measures
Primary Outcome Measures
- Maximal tolerance dose (MTD) [Up to 2 years.]
If dose limiting toxicity (DLT) occurs in 2 or more subjects in a given dose group, the dose level in the previous dose group is considered MTD.
- Recommended phase II dose (RP2D) [Up to 2 years]
The RP2D is defined as the lower dose level to MTD based on the safety profile.
- ≥35% reduction in spleen volume (SVR35) [Up to 24 weeks]
The proportion of subjects with a ≥35% reduction in spleen volume from baseline at the end of treatment at week 24.
Secondary Outcome Measures
- SVR35 [Up to 120 weeks]
The proportion of subjects with a ≥35% reduction in spleen volume compared to baseline after treatment.
- Optimum effective rate [Up to 120 weeks]
The proportion of subjects with at least once spleen volume reduction ≥ 35% from baseline.
- Onset time of splenic response [Up to 120 weeks]
The time interval from the first administration to the date when the spleen volume was reduced by ≥ 35 % from baseline.
- Duration of maintenance of at least 35% Reduction in Spleen Volume (DoMSR) [Up to 120 weeks]
The time between the date when the spleen volume reduction ≥ 35% from baseline occurs for the first time and the date when the spleen volume reduction is < 35% from baseline.
- Myeloproliferative neoplasm - Symptom Assessment Form - Total Symptom Score (MPN-SAF TSS) [Up to 60 weeks]
The proportion of subjects whose total symptom score of MPN-SAF TSS decreased by more than 50% from baseline. MPN-SAF-TSS is an effective tool for evaluating the disease burden of patients with myeloproliferative neoplasms. Each symptom is scored according to the severity, from asymptomatic (0 points) to the most serious (10 points), a total of 10 levels, the sum of 10 symptom scores is MPN-SAF-TSS score. The higher the score, the more severe the symptoms are.
- MPN-SAF TSS change [Up to 120 weeks]
The total score of MPN-SAF TSS decreased compared with baseline. MPN-SAF-TSS is an effective tool for evaluating the disease burden of patients with myeloproliferative neoplasms. Each symptom is scored according to the severity, from asymptomatic (0 points) to the most serious (10 points), a total of 10 levels, the sum of 10 symptom scores is MPN-SAF-TSS score. The higher the score, the more severe the symptoms are.
- Variant allele frequency (VAF) [Up to 48 weeks]
The proportion of subjects whose VAF decreased compared with baseline.
- The proportion of subjects with gene mutation achieving SVR35 [Up to 48 weeks]
The proportion of subjects with gene mutation achieving SVR35
- The proportion of subjects with gene mutation whose MPN-SAF TSS scale decreased by ≥ 50% [Up to 48 weeks.]
The proportion of subjects with gene mutation whose MPN-SAF TSS scale decreased by ≥ 50% compared with baseline.
- Progression-free survival (PFS) [Up to 120 weeks]
The time interval from the first dose to the date of the occurrence of any of the following events, whichever occurs first:(1) Spleen volume increased by ≥25% compared with the screening period ; (2) Death caused by any cause.
- Leukemia free survival (LFS) [Up to 120 weeks]
The time interval from the date of the first dose to the date of any of the following events, whichever occurs first: (1) the date of the first bone marrow smear showing the original cell ≥20% ;(2) The first peripheral blood smear showed that the original cells ≥ 20% and the absolute value of the original cells ≥1×10^9/L and lasted for at least 2 weeks; (3) Death caused by any reason.
- Overall Survival (OS) [Up to 120 weeks]
OS is defined as the time from the first time the subject received treatment to death due to any cause.
- Incidence of adverse events (AEs) [Baseline up to 120 weeks]
Incidence rate of all adverse medical events that occur after the subject receives the investigational drug, evaluated according to the Common Terminology Criteria for Adverse Events Version 5.0 (CTCAE v5.0)
- Severity of adverse events (AEs) [Baseline up to 120 weeks]
Severity of all adverse medical events that occur after the subject receives the investigational drug, evaluated according to the Common Terminology Criteria for Adverse Events Version 5.0 (CTCAE v5.0)
