Ability to understand the requirements of the trial, to provide written informed consent (including consent for the use and disclosure of research-related health information), and to comply with the trial protocol procedures (including required trial visits).
Male or female patient aged ≥18 years.
Confirmed ITP diagnosis, at least 3 months before randomization and according to the American Society of Hematology Criteria, and no known other etiology for thrombocytopenia.
Diagnosis supported by a response to a prior ITP therapy (other than thrombopoietin receptor agonists \[TPO-RAs\]), in the opinion of the investigator.
Mean platelet count of \<30×10E9/L from 2 counts: 1 platelet count collected during the screening period and the predose platelet count on the day of randomization.
At the start of the trial, the patient is either on concurrent ITP treatment(s) and has received at least 1 prior therapy for ITP in the past, or the patient is not on treatment for ITP but has received at least 2 prior treatments for ITP. Patients receiving permitted concurrent ITP treatment(s) at baseline, must have been stable in dose and frequency for at least 4 weeks prior to randomization.
Women of childbearing potential must have a negative serum pregnancy test at the screening visit and a negative urine pregnancy test at baseline before trial medication (infusion) can be administered.
Women of childbearing potential should use a highly effective or acceptable method of contraception during the trial and for 90 days after the last administration of the IMP.
You may not be if
ITP/thrombocytopenia associated with another condition, eg, lymphoma, chronic lymphocytic leukemia, viral infection, hepatitis, induced or alloimmune thrombocytopenia, or thrombocytopenia associated with myeloid dysplasia.
Use of certain medications before the start of the studies (more details in the protocol)
Patients who have a history of malignancy, including malignant thymoma, or myeloproliferative or lymphoproliferative disorders, unless deemed cured by adequate treatment with no evidence of recurrence for ≥3 years before screening. Patients with completely excised non-melanoma skin cancer (such as basal cell carcinoma or squamous cell carcinoma) or cervical carcinoma in situ would be permitted at any time.
Uncontrolled hypertension, defined as a repeated elevated blood pressure exceeding 160 mmHg (systolic) and/or 100 mmHg (diastolic) despite appropriate treatments.
History of any major thrombotic or embolic event within 12 months prior to randomization.
History of coagulopathy or hereditary thrombocytopenia or a family history of thrombocytopenia.
History of a recent or planned major surgery (that involves major organs eg, brain, heart, lung, liver, bladder, or gastrointestinal tract) within 4 weeks of randomization.
Positive serum test at screening for an active viral infection with any of the following conditions: Hepatitis B virus (HBV), Hepatitis C virus (HCV), Human immunodeficiency virus (HIV)
Clinical evidence of significant unstable or uncontrolled acute or chronic diseases other than ITPdespite appropriate treatments which could put the patient at undue risk.
Patients with known medical history of hypersensitivity to any of the ingredients of the IMP.
Patients who previously participated in a clinical trial with efgartigimod and have received at least 1 administration of the IMP.
Pregnant or lactating females. More details in the protocol
