Rice-derived Recombinant Human Serum Albumin for the Treatment of Hypoalbuminemia After Hepatectomy: A Prospective, Single-Arm, Exploratory Clinical Trial
Sponsor: Cheng Qi
Summary
Rice-derived recombinant human serum albumin (OsrHSA) possesses an identical primary, secondary, and higher-order structure to plasma-derived human albumin. Through innovative production technology, it fundamentally circumvents the supply limitations and viral contamination risks associated with plasma sources, offering a novel solution to address clinical unmet needs. Existing research data have demonstrated that its efficacy and safety are non-inferior to plasma-derived human albumin in patients with cirrhosis complicated by hypoalbuminemia. However, no study has yet explored the safety and efficacy of OsrHSA in patients with postoperative hypoalbuminemia following hepatectomy. This study is a prospective, single-arm, small-sample, exploratory clinical trial aimed at evaluating the efficacy and safety of recombinant human serum albumin injection (rice) (OsrHSA) in patients with hypoalbuminemia after hepatectomy. All trial participants will receive daily intravenous infusion of 20 g OsrHSA (20%, 50 mL) starting from the day when postoperative hypoalbuminemia (\<30 g/L) is identified, with concurrent monitoring of serum albumin levels. The primary endpoints are the percentage of trial participants achieving serum albumin ≥35 g/L within one week, and the incidence of adverse drug reactions.

Rice-derived recombinant human serum albumin (OsrHSA)
All trial participants will receive daily intravenous infusion of 20 g Rice-derived recombinant human serum albumin (OsrHSA, 20%, 50 mL) starting from the day when postoperative hypoalbuminemia is identified, for a maximum duration of 7 days, with concurrent monitoring of serum albumin levels. Study drug administration will be discontinued once serum albumin reaches ≥35 g/L, and participants will enter the follow-up period. Each trial participant will undergo one follow-up visit within 30 days after treatment.
