  • •Confirmed diagnosis of primary ITP for at least 3 months at screening.
  • •Previous treatment with corticosteroids.
  • •At the last ITP treatment, participants experienced loss of remission, no remission, relapse after remission, or intolerance.
  • •Platelet count <30×10⁹/L at screening with clinical assessment indicating treatment necessity
  • •Participants must have adequate organ function
  • •Clinically stable condition with World Health Organization (WHO) bleeding scale grade 0-1
  • •Female participants of childbearing potential or male participants with fertile partners must refrain from sperm/ova donation from ICF signing until 12 weeks after last dose and agree to protocol-specified contraceptive measures

排除标准

  • •Diagnosis of secondary thrombocytopenia or concomitant autoimmune hemolytic anemia
  • •Received platelet transfusion, whole blood transfusion, plasma exchange, or any other emergency treatment drugs within 14 days prior to the first infusion of SHR-2173
  • •Received immunosuppressants (other than corticosteroids) such as Janus kinase [JAK] inhibitors or Bruton tyrosine kinase [BTK] inhibitors within either 5 times the drug elimination half-life or 14 days prior to the first infusion of SHR-2173 (whichever is longer)
  • •Previous treatment with SHR-2173
  • •Screening prothrombin time or activated partial thromboplastin time outside the normal range; concurrent coagulation disorders and/or receiving antiplatelet or anticoagulant medications (e.g., warfarin, clopidogrel, novel oral anticoagulants), except for low-dose acetylsalicylic acid
  • •History of any thrombotic or embolic events within 12 months prior to the first administration, or clinical symptoms and history suggesting thrombophilia
  • •Current life-threatening bleeding (related to thrombocytopenia) or expected to require emergency treatment within one week after randomization
  • •Active viral, bacterial, or other infections (including tuberculosis [TB]) requiring systemic treatment at screening, or SARS-CoV-2 infection during screening, or history of clinically significant recurrent infections
  • •Received live or attenuated live vaccines within 8 weeks prior to the first administration of SHR-2173, or planned to receive live/attenuated vaccinations during the trial
  • •Received live or attenuated live vaccines within 8 weeks prior to the first administration of SHR-2173, or planned to receive live/attenuated vaccinations during the trial
  • •Diagnosis of myelodysplastic syndrome; history of or current malignancy within 5 years prior to screening (except for cured non-melanoma skin cancer, in situ carcinoma [e.g., cervical, breast, bladder, prostate cancer], and cancers in complete remission for at least 5 years with no evidence of recurrence)
  • •Previous splenectomy
  • •Previous allogeneic stem cell or organ transplantation (except for corneal transplantation ≥ 3 months prior to screening); known or suspected history of immunosuppression
  • •Planned surgery during the dosing period
  • •Any severe and/or unstable pre-existing medical, psychiatric, or other conditions that the investigator judges may interfere with patient safety, obtaining informed consent, or compliance with study procedures
  • •Allergic constitution (e.g., allergies to two or more drugs, foods, or pollens) or known hypersensitivity (immediate or delayed) or atopic reactions to the study drug (including excipients, monoclonal antibodies)
  • •Concurrent participation in other investigational studies within either 30 days prior to enrollment or 5 half-lives of the investigational drug (whichever is longer)
  • •Females who are lactating or pregnant (positive serum or urine β-human chorionic gonadotropin [hCG]) at screening or on Day 1 of Week 1 prior to administration
