健康な参加者、および慢性B型肝炎感染症に罹患している参加者における単独およびベピロビルセンとの組み合わせにおけるGSK3965193の研究

2026年5月19日 更新者:GlaxoSmithKline

健康な参加者および一緒に生活している参加者におけるGSK3965193単剤療法の安全性、忍容性、薬物動態、および薬力学を評価するための4部構成、無作為化、二重盲検(パート1、2A、3および4)、多施設、プラセボ対照研究慢性 B 型肝炎感染;慢性B型肝炎感染症に罹患している参加者におけるベピロビルセンとの併用におけるおよびGSK3965193

この第 1/2a 相試験は、GSK3965193 の単回投与 (第 1 部) および反復投与 (第 2 部) の安全性、忍容性、および薬物動態 (PK) を評価するために設計された初回投与 (FTIH) 試験です。健康な参加者。 パート 3 では、慢性 B 型肝炎感染症 (PLWCHB) を患っている参加者の B 型肝炎ウイルス表面抗原 (HBsAg) を低下させる GSK3965193 の能力を評価します。 パート 4 では、GSK3965193 とベピロビルセンによる併用療法の安全性と忍容性、および PLWCHB で持続的なウイルス学的反応をもたらす可能性を評価します。

An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of a study intervention, whether or not considered related to the study intervention.

An AE was considered treatment emergent if the AE onset date was on or after study intervention start date (i.e., Day 1) till Day 5 after study intervention administration. Any AE which started post Day 5 of study intervention administration was not considered as TEAE.
