简要总结
This is a trial in which 350 primary lung transplant recipients will be randomized (1:1) to receive either Tocilizumab (six doses over 20 weeks) plus standard triple maintenance immunosuppression or placebo (sterile normal saline) plus standard triple maintenance immunosuppression (Tacrolimus, Mycophenolate Mofetil, corticosteroids).
The primary objective is to test the hypothesis that treatment with triple maintenance immunosuppression plus Tocilizumab (TCZ) is superior to triple maintenance immunosuppression plus placebo (saline) as defined by a composite endpoint of a) CLAD, b) listed for re-transplantation, and c) death

结局指标
主要结局
Proportion of subjects who meet any one of the pre-specified events detailed in the outcome description: from Baseline up to 36 months
时间窗: Over a period of 3 years after randomization
1. The development of Chronic Lung Allograft Dysfunction (CLAD) * The development of any form of CLAD will be defined according to the standard 2019 The International Society for Heart and Lung Transplantation (ISHLT) criteria. 2. Listed for re-transplantation * Re-transplantation defined as the subject has been formally registered on the United Network for Organ Sharing (UNOS) waiting list to undergo a second lung transplant surgery 3. Death * Primary analysis will be conducted according to an Intent-to-treat (ITT) principle and therefore will include all randomized subjects who receive Tocilizumab(TCZ) or placebo. The time from randomization to development of CLAD will be compared between the two treatment groups (TCZ vs. placebo) using a Pearson's chi-square test.
