GGF2 (USAN cimaglermin alfa) is an investigational drug for the treatment of heart failure. During Phase 1 clinical trials, concomitant, transient elevations in serum aminotransferases (ALT/AST) and bilirubin meeting FDA DILI Guidance stopping criteria (Hy’s Law) were observed in two treated subjects but resolved within 2 weeks, with no further LFT abnormalities over the following 1-3 years. GGF2 has no direct toxic effect on human hepatocytes in vitro, so further exploration of these cases was undertaken.
