ETNB Readout

Pegozafermin is in a Phase 2b trial in NASH. This trial started in 2021 and so far no data has been reported. Previously, Phase 1b/2a data was reported throughout 2020 and 2021 at multiple conferences including ENDO 2021 and AASLD 2021, and topline data was reported January 24, 2022. This positive data showed that 63% of patients achieved 2-point or greater improvement in NASH without worsening of fibrosis. There were clinically meaningful improvements on the registration enabling endpoints of NASH resolution (32%) and fibrosis improvement (26%). After interim data from the Phase 1b/2a trial was reported previously, the Phase 2b ENLIVEN trial was allowed to initiate in June 2021. See Figures 1 & 2 (below) for more info from the Phase 1b/2a trial.

The Phase 2b ENLIVEN trial is evaluating several doses of subcutaneous injection of Pegozafermin against a placebo subcutaneous injection. The dual primary outcomes are to determine the number of participants with resolution of NASH without worsening of fibrosis and number of patients with at least 1 stage decrease in fibrosis stage with no worsening of NASH, both measured at 24 weeks. These endpoints are very common in NASH trials including the Phase 3 MDGL MAESTRO-NASH trial, Phase 3 ICPT REGENERATE trial, and Phase 2b AKRO HARMONY trial. See our previous MDGL article HERE for deeper analysis of these three trials.


It will be very interesting to see how the ENLIVEN data compares to these previous trials, especially to the AKRO HARMONY trial data. Both AKRO's Efruxifermin and ETNB's Pegozafermin are FGF21 analogs. The Phase 2b AKRO data showed improvement in fibrosis with no worsening of NASH and reduction of NASH with no worsening of fibrosis. However, compared to the ICPT and MDGL trials, the AKRO trial had the highest placebo rate and greatest occurrence of diarrhea and nausea adverse events. See Figure 3 for the trial design of the Phase 2b ENLIVEN trial.
