Clinical Trial Summary

Clinical Study on the Safety and Effectiveness of Autologous Hematopoietic Stem Cell Transplantation Combined With CAR-T Cells in the Treatment of Refractory and Relapsed Multiple Myeloma

Description:

This is a prospectiv , single arm, open-label, single-center study. This study is indicated for refractory and relapsed multiple myeloma. It aims to evaluate the safety and effectiveness of autologous hematopoietic stem cell transplantation combined with BCMA CAR-T to treat refractory and relapsed multiple myeloma. The main research is completely alleviated, overall reaction rate, and recurrence rate,etc. 50 patients will be enrolled.

• Accepts healthy volunteers: No
• Gender: All
• Age group: 30 Years to 75 Years

Eligibility

Inclusion Criteria:

• 1?BCMA positive accompanied by refractory/relapsed and resistance;

• 2?Patients with the tumor load is high and cannot be transplanted directly, before transplantation. Reduce the load through CAR-T treatment to prepare for transplantation;

• 3?Patient relapses after transplantation,donor lymphocyte infusion Invalid. The donor cells in the recipient body can be used or the donor cells can be collected directly.Prepare CAR-T to prevent recurrence and induce relapsing;

• 4?Repeated MRD (+) refractory drug resistant cases;

• 5?Male or female, 30-75 years old;

• 6?Anticipated survival time more than 12 weeks

• 7?Transplant subjects, regardless of their previous treatment, are eligible for inclusion after relapse;

• 8?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;

• 9?Those who voluntarily participate in the trial and sign the informed consent form

Exclusion Criteria:

• 1?Patients with the history of epilepsy or other CNS disease;

• 2?Patients with prolonged QT interval time or severe heart disease;

• 3?Pregnant or breastfeeding;

• 4?Active infection with no cure;

• 5?Patients with active hepatitis B or C infection;

• 6?Previously treated with any genetic therapy;

• 7?The proiferation rate is less than 5 times response to CD3/CD28 co-stimulation signal;

• 8?Serum creatinine > 2.5mg/dl or ALT / AST > 3 times ULN or bilirubin > 2.0mg/dl;
