Safety, Tolerability, and Pharmacokinetic Study of 101BHG-D01 Nasal Spray, a Novel Long-Acting and Selective Cholinergic M Receptor Antagonist, in Healthy Chinese Volunteers: A Randomized, Double-Blind, Placebo-Controlled, Single-Dose Escalation, First-In-Human Study.

Background And Objective: 101BHG-D01 nasal spray is the first novel long-acting cholinergic M receptor antagonist under development to treat rhinorrhea in rhinitis. This first-in-human study aimed to evaluate the safety, tolerability, and pharmacokinetics of 101BHG-D01 nasal spray following single intranasal doses in healthy Chinese subjects.

Methods: A randomized, double-blind, placebo-controlled, single-dose escalation study was conducted in healthy Chinese volunteers after intranasal doses of 101BHG-D01 nasal spray or placebo ranging from 40 µg to 960 µg (total of six doses).

Bioequivalence Study of Palbociclib Capsules in Healthy Chinese Subjects Under Fasting and Fed Conditions.

Background And Objective: Palbociclib is an oral small-molecule inhibitor of cyclin-dependent kinase 4/6 used for the treatment of advanced breast cancer. This study compared the pharmacokinetic and safety profiles between a new generic and a branded reference formulation of palbociclib capsules in healthy Chinese subjects under fasting and fed conditions and evaluated the bioequivalence of two palbociclib products to obtain sufficient evidence for the marketing approval of the new generic drug.

Methods: A randomized, open-label, two-period crossover study was conducted in healthy Chinese volunteers under both fasting and fed conditions (30 subjects/condition).
