Key result

Adenovirus-mediated PD-L1.Ig gene transfer significantly prolonged median cardiac allograft survival to 17 days compared to 11 and 9 days for controls (P < 0.001).

Overview

Supports PD-L1 gene therapy investigation in transplant models; leaves open translation to human cardiac allograft survival.

Structured PICO

Does adenovirus-mediated PD-L1.Ig gene transfer prolong cardiac allograft survival in a rat model?

P
Population
F344 rat donor hearts transplanted into Lewis recipients to evaluate cardiac allograft survival.
I
Intervention
Adenovirus-mediated PD-L1.Ig gene transfer (with or without subtherapeutic cyclosporin A)
C
Comparator
Noncoding adenovirus or virus dilution buffer alone (with or without subtherapeutic cyclosporin A)
O
Outcome
Cardiac allograft survival (median survival time)surrogate

Main Result

Absolute Event Rate: 17% vs 11%

p-value: p=< 0.001

Localized PD-L1.Ig gene transfer attenuates acute cardiac allograft rejection in a rat model, with additive effects when combined with subtherapeutic cyclosporin A.

Cite This Study

Dudler et al. (2006) studied Cardiac allograft rejection. Adenovirus-mediated PD-L1.Ig gene transfer vs. Noncoding adenovirus or virus dilution buffer alone was evaluated on Median survival time (p=< 0.001). Adenovirus-mediated PD-L1.Ig gene transfer significantly prolonged median cardiac allograft survival to 17 days compared to 11 and 9 days for controls (P < 0.001).
