Multiple Ascending Dose Study to Evaluate the Safety, Tolerability and Pharmacokinetics of KSHN001034 in Healthy Postmenopausal Female Volunteers

The goal of this clinical trial is to evaluate if KSHN001034 demonstrates safety, tolerability, and a comparable pharmacokinetic (PK) profile to the reference product, Faslodex® (fulvestrant), which is used for the treatment of hormone receptor-positive breast cancer. Participants will: Receive either the test product (KSHN001034) or the reference product (Faslodex®) administered intramuscularly (IM) or subcutaneously (SC) at doses of low, medium, or high , with doses conducted in 5 cohorts and these participants will be healthy postmenopausal female volunteers. Dosing will be administered in a sequential cohort-wise manner across five cohorts, with DSMB oversight for safety monitoring and dose escalation. Primary Endpoint: Safety and tolerability will be assessed based on the occurrence, severity, and relationship of adverse events (AEs), including serious adverse events (SAEs). Secondary Endpoint: Pharmacokinetic (PK) parameters will be evaluated, including Cmax (maximum concentration), Tmax (time to maximum concentration), AUC (area under the curve), and T1/2 (half-life).
