About this trial
To evaluate the safety and efficacy of nicotinamide adenine dinucleotide in the treatment of immune thrombocytopenia in patients who have not responded adequately or relapsed after first-line treatment and at least one second-line therapy including Anti-CD20 Antibody and/or TPO-RA.
Eligibility criteria
Qualifiers
Age 18 and above, male or female;
Conform to the diagnostic criteria of immune Thrombocytopenia (ITP) ≥3 months;
Failure to achieve response or relapse after corticosteroid therapy, and failure to achieve response or relapse after previous second-line treatments such as TPO/TPORAs therapy, or are unable to afford the cost of the treatment;
The platelet count of <30 X 10^9/L measured within 2 days prior to inclusion (During the screening visit and/or before receiving the study drug, platelet counts must be less than 30×10^9/L on at least two consecutive occasions, with a minimum interval of 1 day between the two tests.);
Disqualifiers
Those who are allergic to Nicotinamide adenine dinucleotide or excipients, or who have previously received CD38 monoclonal antibody treatment with no efficacy.
Those with autoimmune hemolytic anemia, or various types of secondary and genetic thrombocytopenia, such as leukemia, lymphoma, multiple myeloma, aplastic anemia, myelodysplastic syndrome, Evans syndrome, common variable immunodeficiency, systemic lupus erythematosus, cirrhosis, antiphospholipid antibody syndrome, pseudo-thrombocytopenia, drug-induced thrombocytopenia (e.g., quinine, heparin, antimicrobial drugs, anticonvulsants, etc.).
A history of any thrombosis or embolism events within 12 months prior to the first dose, or the presence of extensive and severe bleeding, such as hemoptysis, upper gastrointestinal bleeding, intracranial hemorrhage, sepsis, or other irregular bleeding.
Participation in any other clinical trial involving investigational drugs (including vaccine studies) or exposure to other investigational drugs within 4 weeks or 5 half-lives (whichever is longer) prior to the first dose.
