入选标准
- •Subjects must meet the following criteria in order to be eligible for the study:
- •1. Adults =18 years of age and able to provide informed consent.
- •2. Confirmed diagnosis of primary MF, post-PV MF, or post-ET MF, as assessed by treating physician according to the World Health Organization (WHO) criteria
- •3. Subjects with TP53 WT MF, defined as tumors that do not harbor deleterious alteration in TP53
- •4. Palpable spleen measuring =5 cm below the left lower costal margin or spleen volume of =450 cm3 by MRI or CT scan assessment
- •5. MF symptoms as defined by having at least 2 symptoms with a score of at least 1 each on the MFSAF v4.0
- •6. High-risk, intermediate-2 risk, or intermediate-1 risk, defined by Dynamic International Prognostic System (DIPSS) or DIPSS-PLUS
- •7. Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 2 according to ECOG performance status criteria
- •8. Adequate hematological, hepatic, and renal organ function (as per protocol definition and within 7 days [Phase 1b] or 28 days [Phase 2] prior to the first dose of study treatment)
- •a. Hematologic:
- •i. Absolute neutrophil count (ANC) =1.0×10^9/L (Note: ANC eligibility is based on values obtained in the absence of growth factors, ie, 7 days for granulocyte colony-stimulating factor (G-CSF) or 14 days for pegfilgrastim)
- •ii. Platelet count =50×10^9/L
- •iii. Peripheral blood blast count <10%
- •b. Hepatic:
- •i. Total bilirubin within normal limits if total bilirubin is >upper limit of normal (ULN), then subjects are eligible if the direct bilirubin is =2.0×ULN, unless Gilbert's Syndrome
- •ii. Aspartate transaminase/serum glutamic oxaloacetic transaminase and alanine transaminase/serum glutamic pyruvic transaminase =2.5×ULN
- •i. Estimated creatinine clearance (eCcr) =30 mL/min by Cockcroft Gault.
- •9. Female subjects of childbearing potential and their male partners, or male subjects who have female partners of childbearing potential must both use highly effective contraception method during the study. In addition, male subjects must continue to use contraception for 3 months and 1 week after the last dose of study drug and female subjects must continue to use contraception for 1 month and 1 week after the last dose of study drug. A woman is considered of childbearing potential (ie, fertile, following menarche and until becoming post-menopausal) unless permanently sterile.
- •Must have R/R MF following JAK inhibitor treatment that meets either criterion (1) or (2) below:
- •1. Relapsed defined by one of the following:
- •a. Spleen volume increase by =25% by radiographic imaging from nadir
- •b. =100% increase in palpable distance below the left lower costal margin (LLCM), for Baseline splenomegaly of 5 to 10 cm
- •c. =50% increase in palpable distance below the LLCM, for Baseline splenomegaly of >10 cm
- •d. Regrowth after achieving complete response
- •2. Refractory defined by one of the following after receiving =12 weeks of JAK inhibitor treatment:
- •a. <10% spleen volume reduction by radiographic imaging
- •b. <30% decrease from Baseline in spleen size by palpation
- •Are the trial subjects under 18? no
- •Number of subjects for this age range:
- •F.1.2 Adults (18-64 years) yes
- •F.1.2.1 Number of subjects for this age range 26
- •F.1.3 Elderly (>=65 years) yes
- •F.1.3.1 Number of subjects for this age range 25
排除标准

- •5. Participation in another interventional clinical study within the past 28 days of the first dose of study treatment (participation in observational studies is permitted)
- •6. Prior splenectomy
- •7. Splenic irradiation within 12 weeks prior to the first dose of study treatment
- •8. Prior allogeneic stem-cell transplantation or eligible for allogeneic stem cell transplantation in the opinion of the Investigator; subjects that refuse a transplant are eligible for enrollment in this study.
- •9. Women who are pregnant or breastfeeding
- •10. History of major organ transplant
- •11. Uncontrolled intercurrent illness including, but not limited to, clinically significant cardiac disease (New York Heart Association Class III or IV); symptomatic congestive heart failure; unstable angina pectoris; unstable ventricular arrhythmia; or psychiatric illness/social situations that would limit compliance with study requirements
- •12. Subjects with active hepatitis B virus or hepatitis C virus
- •13. Subjects with known history of human immunodeficiency virus (HIV)
- •14. Subjects with clinically significant bacterial, fungal, parasitic, or viral infection that requires therapy. Subjects with acute bacterial infections requiring antibiotic use should delay screening/enrollment until the course of antibiotic therapy has been completed.
- •15. Other malignancy within the last 3 years, other than curatively treated basal cell or squamous cell skin cancer, carcinoma in situ of the cervix, organ-confined or treated nonmetastatic prostate cancer with normal prostate-specific antigen, in situ breast carcinoma after complete surgical resection, or superficial transitional cell bladder carcinoma
