Siltuximab for Antibody-Mediated Rejection After Lung Transplant

This study is testing a new approach for people who have antibody-mediated rejection (AMR) after a lung transplant. AMR is a serious condition where your body's immune system attacks the transplanted lung. We are looking at the safety of adding a medication called Siltuximab to your usual treatment for AMR. Siltuximab works by blocking a protein called Interleukin-6 (IL-6), which plays a role in inflammation and immune responses. This study will enroll 30 participants who are 18 years or older and have a new diagnosis of AMR. The main goal is to see how safe Siltuximab is by tracking any serious side effects for 90 days. If this study shows Siltuximab is safe, future studies will be needed to see how well it works.

Study design
This is an interventional study with a planned enrollment of 30 participants. It is testing Siltuximab against a placebo (an inactive substance).
What's involved
Not specified in the trial record.
Compensation
Not stated in the trial record.
Follow-up
The study will track serious side effects for 90 days after randomization.

    The primary objective is to assess the safety and tolerability of Siltuximab added to routine immunosuppressive treatment for AMR after lung transplantation. The dose of siltuximab (11mg/kg or 5.5 mg/kg) with the least side effect profile will be use for future trials of siltuximab in antibody mediated rejection in lung transplantation.
