Name
LNA-2024

Treatment
Lusutrombopag
Administer lusutrombopag at 3mg/qd orally for 12 weeks (lusutrombopag starting dose is 3mg, once daily. After 2 weeks of continuous administration, the dose can be increased by 3mg every 2 weeks based on the platelet count and safety of the subject. The dose can be gradually increased to 9mg/d over a total of 12 weeks). The course should be at least 3 months. When the platelet increase is \<20×109/L, the daily dose can be increased by 3mg up to a maximum of 9mg/day; when the platelet increase is ≥50×10\^9/L and ≤200×10\^9/L, the dose can be maintained; when the platelet count is ≥200×10\^9/L and ≤400×10\^9/L, the daily dose can be reduced by 3mg; when the platelet count is \>400×10\^9/L, the drug can be suspended and resumed when the platelet count decreases to \<200×10\^9/L, with the daily dose reduced by 3mg. In this case, if the lowest dose of 3mg/day is used, the drug can be suspended. Responders continue treatment until 6 months.

Eligibility criteria
Inclusion Criteria: 1. Participants must be at least 18 years old, male or female. 2. Participants must be diagnosed with NSAA and have a refractory/relapsed/intolerable response to standard-dose cyclosporine (CsA). The definition of refractory/relapsed is patients who have been treated with sufficient doses of cyclosporine (3-5mg/kg) for at least 6 months without response or relapse. The definition of intolerable is patients who cannot tolerate CsA and have stopped treatment due to significant side effects. 3. Participants must meet the following criteria at enrollment: platelets \<30×109/L. 4. Baseline liver and kidney function must be within 2 times of normal range. 5. No active infection; no pregnancy or breastfeeding. 6. Participants must agree to sign the informed consent form. 7. Eastern Cooperative Oncology Group (ECOG) performance status score of 0-2. Exclusion Criteria: 1. Other causes of pancytopenia, such as myelodysplastic syndrome (MDS). 2. Evidence of clonal hematopoietic system bone marrow disease (MDS, AML) with cytogenetics. 3. PNH clone ≥50%. 4. Received hematopoietic stem cell transplant (HSCT) prior to enrollment. 5. Received ATG treatment within 6 months prior to enrollment. 6. Infection or bleeding that cannot be controlled with standard therapy. 7. Allergic to ruxolitinib. 8. Active HIV, HCV, or HBV infection, cirrhosis, or portal hypertension. 9. Any malignant tumor within 5 years, or local basal cell carcinoma of the skin. 10. History of thromboembolic events, myocardial infarction, or stroke (including antiphospholipid syndrome) and current use of anticoagulants. 11. Pregnant or breastfeeding (lactating) women. 12. Participated in another clinical trial within 3 months.
