[Translation] A single oral, randomized, open-label, two-period, crossover bioequivalence study of L-glutamine sodium guarenate granules in healthy subjects after fasting (preliminary study)
主要目的:通过小样本量的预试验研究,考察中国健康受试者在空腹条件下单剂量口服江苏诚康药业有限公司生产的L-谷氨酰胺呱仑酸钠颗粒(规格:0.67g(L-谷氨酰胺663.3mg,呱仑酸钠2.0mg)/袋)与持证商 Kotobuki Pharmaceutical Co., Ltd.的L-谷氨酰胺呱仑酸钠颗粒(商品名:MARZULENE-S®,规格:0.67g(L-谷氨酰胺663.3mg,呱仑酸钠2.0mg)/袋)制剂的相似程度,考察药物的体内药代动力学特征,为能否进入正式试验提供决策依据,并验证正式试验样本量、采血点、试验周期间隔及分析方法等设置的合理性。
次要目的:评价单剂量口服L-谷氨酰胺呱仑酸钠颗粒受试制剂(规格:0.67g(L-谷氨酰胺663.3mg,呱仑酸钠2.0mg)/袋)及参比制剂(商品名:MARZULENE-S®,规格:0.67g(L-谷氨酰胺663.3mg,呱仑酸钠2.0mg)/袋)在中国健康受试者中的安全性。
[Translation] Main purpose: Through a small sample size pilot study, to investigate the similarity between a single oral dose of L-glutamine sodium guarenate granules (specification: 0.67g (L-glutamine 663.3mg, sodium guarenate 2.0mg)/bag) produced by Jiangsu Chengkang Pharmaceutical Co., Ltd. and L-glutamine sodium guarenate granules (trade name: MARZULENE-S®, specification: 0.67g (L-glutamine 663.3mg, sodium guarenate 2.0mg)/bag) produced by the licensed manufacturer Kotobuki Pharmaceutical Co., Ltd. in Chinese healthy subjects under fasting conditions, to investigate the in vivo pharmacokinetic characteristics of the drug, to provide a decision-making basis for whether to enter the formal trial, and to verify the rationality of the formal trial sample size, blood collection points, test cycle intervals and analysis methods.
Secondary objective: To evaluate the safety of a single-dose oral L-glutamine sodium guarenate granules test formulation (specification: 0.67 g (L-glutamine 663.3 mg, sodium guarenate 2.0 mg)/bag) and reference formulation (trade name: MARZULENE-S®, specification: 0.67 g (L-glutamine 663.3 mg, sodium guarenate 2.0 mg)/bag) in healthy Chinese subjects.
