A Clinical Study on the Safety and Effectiveness of CD19/BCMA Chimeric Antigen Receptor T Cells in the Treatment of Refractory POEMS Syndrome, Amyloidosis, Autoimmune Hemolytic Anemia, and Vasculitis

A Clinical Study on the Safety and Effectiveness of CD19/BCMA Chimeric Antigen Receptor T Cells in the Treatment of Refractory POEMS Syndrome, Amyloidosis, Autoimmune Hemolytic Anemia, and Vasculitis

Study Overview

Detailed Description

POEMS syndrome, amyloidosis, autoimmune hemolytic anemia, vasculitis and other diseases may only show local pathological damage or systemic lesions. If they are not diagnosed and treated in time or poorly controlled, they will progress as the course of the disease progresses. Risk of disability or even death.

Description

Inclusion Criteria:

  • 1. Diagnosed with POEMS syndrome, amyloidosis, autoimmune hemolytic anemia, vasculitis, and the curative effect of conventional hormones, radiotherapy and chemotherapy, protease inhibitors is not good and (or) no effective treatment means.

    2. After glucocorticoids, cyclophosphamide or methotrexate treatments there are still relapsed and refractory diseases, or clearly show intolerance/toxicity to these drugs.

    3. Estimated survival time> 12 weeks; 4. Patients had a negative urine pregnancy test before the start of administration and agreed to take effective contraceptive measures during the test period until the last follow-up; 5. Patients or their legal guardians volunteer to participate in the study and sign the informed consent.

Exclusion Criteria:

  • Subjects with any of the following exclusion criteria were not eligible for this trial:

    1. History of craniocerebral trauma, conscious disturbance, epilepsy,cerebrovascular ischemia, and cerebrovascular, hemorrhagic diseases;
    2. Electrocardiogram shows prolonged QT interval, severe heart diseases such as severe arrhythm ia in the past;
    3. Pregnant (or lactating) women;
    4. Patients with severe active infections (excluding simple urinary tract infection and bacterial pharyngitis);
    5. Active infection of hepatitis B virus or hepatitis C virus;
