Randomized trial of anakinra plus zinc vs. prednisone for severe alcohol-associated hepatitis

Background & Aims Severe alcohol-associated hepatitis (SAH) has high 90-day mortality. Glucocorticoid therapy for 28 days improves 30- but not 90-day survival. We assessed the efficacy and safety of a combination of anakinra, an IL-1 antagonist, plus zinc (A+Z) compared to prednisone (PRED) using the Day-7 Lille score as a stopping rule in patients with SAH. Methods In this phase IIb double-blind randomized trial in adults with SAH and MELD scores 20-35, participants were randomized to receive either anakinra 100 mg subcutaneously daily for 14 days plus zinc sulfate 220 mg orally daily for 90 days or daily prednisone 40 mg orally for 30 days. Prednisone or prednisone placebo was stopped if Day-7 Lille score was >0.45. All study drugs were stopped for uncontrolled infection or ≥ 5 points increase in MELD score. The primary endpoint was overall survival at 90 days compared using a two-sided log-rank test. Results Seventy-three participants were randomized to PRED and 74 to A+Z. The trial was stopped early after a prespecified interim analysis showed PRED had higher 90-day overall survival (90% vs 70%, HR for death =0.34, 95% CI [0.14, 0.83], P =0.018) and transplant-free survival (88% vs 64%, HR for transplant or death =0.30, 95% CI: [0.13, 0.69], P =0.004) than A+Z. Acute kidney injury was more frequent with A+Z (45%) than PRED (22%) (P = 0.001), but rates of infections were similar (31% in A+Z vs 27% in PRED, P =0.389). Conclusions Participants with SAH treated with prednisone using the Day-7 Lille score as a stopping rule had significantly higher overall and transplant-free 90-day survival and lower incidence of acute kidney injury than those treated with A+Z. Trial Registration NCT04072822. Impact and Implications There is no approved treatment for severe alcohol-associated hepatitis (SAH). In this double-blind randomized trial, patients with SAH treated with prednisone using the Lille stopping rule on Day-7 had higher 90-day overall and transplant-free survival and lower rate of acute kidney injury compared to patients treated with a combination of anakinra and zinc. The data support continued use of glucocorticoids for patients with SAH, with treatment discontinuation for those with Lille score > 0.45 on Day-7.
