A participant who meets all of the following criteria may be included in the study:
1. Men or women, aged 18 years or older.
2. Diagnosis of AIHA based on the presence of hemolytic anemia and serological evidence of anti-erythrocyte antibodies, detectable by the DAT as follows:
a. Warm: DAT positive for IgG only or IgG plus C3d
b. Cold (CAD): DAT positive for C3d only, with cold agglutinins of I specificity
c. Mixed: DAT positive for IgG and C3d, with coexistence of warm autoantibodies and high titer cold agglutinins
3. Participants who have disease progression after treatment with standard therapies that are known to confer clinical benefit, or who are intolerant to treatment. There is no limit to the number of prior treatment regimens.
4. Hemoglobin 7 to 10 g/dL.
5. No evidence of a lymphoproliferative malignancy or other autoimmune-related underlying conditions (eg, systemic lupus erythematosus, Castleman's disease, Sjögren's syndrome, or other autoimmune diseases).
6. ECOG performance status score of 0 to 2.
7. Willingness to avoid pregnancy or fathering children based on the criteria below:
a. Woman of nonchildbearing potential (ie, surgically sterile with a hysterectomy and/or bilateral oophorectomy OR postmenopausal, defined by last menstrual period > 12 months before screening and confirmed by FSH).
b. Woman of childbearing potential who has a negative serum pregnancy test at screening and who agrees to take appropriate precautions to avoid pregnancy (with at least 99% certainty) from screening through at least 93 days after the last dose of study drug. Permitted methods that are at least 99% effective in preventing pregnancy should be communicated to the participant and her understanding confirmed.
c. Man who agrees to take appropriate precautions to avoid fathering children (with at least 99% certainty) from screening through at least 93 days after the last dose of study drug. Permitted methods that are at least 99% effective in preventing pregnancy should be communicated to the participant and his understanding confirmed.
8. Able to comprehend and willing to sign an ICF.
9.Willingness to receive PJP prophylaxis during the study period.
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 17
F.1.3 Elderly (>=65 years) yes
F.1.3.1 Number of subjects for this age range 8
1.Pregnant or breastfeeding women
2.Concurrent conditions and history of other diseases:
a.History or clinical manifes of significant unstable metabolic,hepatic,renal,hematological,pulmonary,cardiovas,gastroint,urolog,neurolog or psychiatric disorders
b.Current or previous malignancy within 5years of study entry,except basal or squamous cell skin cancer with removal considered to be curative,superficial bladder cancer,prostate intraepithel neoplasm,carcinoma in situ of the cervix,or other noninvasive or indolent malignancy without sponsor approval
c.Clinic significant cardiac disease,including unstable angina,acute myocardial infarction,and or cardiac conduction issues within 6months of the date of study drug administration
d.Current NewYorkHeartAssociationClass II to IV congestive heart failure or uncontrolled arrhythmia
3.Inadequate hematologic function defined:
a.ANC <1.5×109/L
b.Platelet count <100 ×109/L
4.Severely impaired liver function(Child-Pugh Class C)or ALTorAST >= 2×ULN on repeated assessment
5.Impaired renal function with estimated creatinine clearance less than45mL/min
6.Anti-phospholipid antibodies positive or elevated anti-streptolysin antibodies
7.Positive serology test results for hepatitis B surface antibody or core antibody, or hepatitis C virus antibody with detectable RNA at screening, consistent with active or chronic infection
8.Known HIV infection or positivity on immunoassay. Note: HIV screening test is optional for participants enrolled in the United States, but participants with known HIV infection enrolled in the United States will be excluded
9.History or presence of an abnormal ECG, that in the investigator’s opinion is clinically meaningful. Participants with screening QTc interval> 470 milliseconds for males and > 480 milliseconds for females (corrected by Fridericia) are excluded. In the event that a single QTcF is >470 milliseconds for males or >480 milliseconds for females, the participant may enroll if the average QTcF for 3 ECGs is <470 milliseconds for males and <480 milliseconds for females
10.Use of the following medications:
a.Treatment with rituximab within 3 months of the baseline visit
b.Use of immunosuppressive therapy within 28 days of the baseline visit. Immunosuppressive therapy includes,but is not limited to, cyclosporine A, tacrolimus, or high-dose corticosteroids. Participants receiving corticosteroids must be at a dose level min= 20mg/day(prednisone or equivalent corticosteroid dose)within 14days of the baseline visit
c.Chronic or current active infectious disease requiring systemic antibiotics,antifungal,or antiviral treatment or exposure to a live vaccine within 28 days of the baselineV
d.Use or expected use during the study of any prohibited medications, including potent CYP3A4 inhibitors or inducers within 14 days or 5 half-lives (whichever is longer)before the baselineV.
e.Current treatment or treatment within 30days or 5half-lives (whichever is longer) before the baselineV with another investigat medication,or current enrollment in another investigational drug protocol
f.Use of any prohibited medications within 14days or 5half-lives(whichever is longer)before the baselineV
11.Known hypersensitivity or severe reaction to INCB050465 or its excipients
12.Unable to swallow oral medication,malabsorption syndrome,disease significantly affecting gastroint function,total resection of the stomach or small bowel, ulcerat colitis,symptomatic inflamm bowel disease,or partial
