Improved outcomes with XueBiJing (XBJ) injection vs placebo have been shown in overall trial populations. We investigated the efficacy and safety of XBJ vs placebo in subjects with severe CAP stratified by age (< 65 and ≥ 65 years).Methods: This post hoc analysis of a large randomized trial compared data from elderly and nonelderly patients with XBJ, 100 mL, q 12 h, or a visually indistinguishable placebo for five-to-seven days.Results: Among subjects ≥ 65 years (n=291), 23 (16.0%) XBJ recipients and 41 (27.9%) placebo recipients (P=0.014) died within 28 days. Among subjects < 65 years (n=360), XBJ still had lower mortality (XBJ 15.6% vs placebo 22.8%; P=0.082), without significantly statistical difference. Total duration of ICU stay and the time of mechanical ventilation were similar in both groups (P> 0.05). XBJ also had a favorable safety profile, with no clinically relevant differences between the two groups. The overall incidence of adverse events was similar in both groups.Conclusion: XBJ was safe and effective for reduction in 28-day mortality among elderly patients with severe CAP. Additional confirmatory trials involving elderly patients are needed to further confirm the present results.Trial Registration: http://www.chictr.org.cn/index.aspx.
