About

KN015,the active substance recombinant human Follicle Stimulating Hormone（FSH） Fc fusion protein, which belongs to the pharmaceutical class gonadotropins.KN015 is proposed for Assisted Reproductive Technology (ART) programs only. Its indication is Controlled Ovarian Stimulation （COS）in combination with a gonadotropin releasing hormone (GnRH) antagonist for the development of multiple follicles in women participating in an ART program. Due to its prolonged duration of FSH activity compared to conventional recombinant FSH (rFSH), a single subcutaneous injection of the recommended dose of KN015 may replace any daily rFSH preparation in a COS treatment cycle. This study is to evaluation of the safety, tolerability, pharmacokinetics and pharmacodynamics of KN015 in healthy Chinese female subjects.

Full description

This is a phase I, randomized, placebo-controlled, single ascending dose, double blind parallel design, first-in-human study. The study design allows a gradual escalation of the dose-level with intensive safety monitoring to ensure the safety of the subjects. Dose escalation will continue until identification of MTD or up to a maximum dose of 100 μg. Tolerability, safety, pharmacokinetics (PK), pharmacodynamics (PD) and immunogenicity characteristics of KN015 will be assessed in healthy female subjects. Eligible subjects will undergo down-regulation of endogenous FSH with a GnRH antagonist Triptorelin prior to receiving KN015.
