Safety, Tolerability, Pharmacodynamic and Pharmacokinetic Effects of Single and Multiple-Doses of ATF936 and AXT914 Administered Orally in Healthy Subjects.
This is a first-in-human study and is designed to evaluate the safety, tolerability, pharmacodynamic and pharmacokinetic effects of a single and multiple-doses of ATF936 and AXT914 administered orally in healthy subjects.
|Study Design:||Allocation: Randomized
Endpoint Classification: Pharmacokinetics/Dynamics Study
Intervention Model: Crossover Assignment
Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
|Official Title:||A Randomized, Double-Blind, Placebo-Controlled, Active Comparator, Ascending Single and Multiple Dose, Seamless Design Study to Explore the Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of Two Orally Administered Compounds, ATF936 and AXT914, in Healthy Male and Female Subjects|
- Phase A: Safety and tolerability of single, oral doses of ATF936 and AXT914 under proposed conditions in healthy male and female subjects. Pharmacokinetics (PK) and pharmacodynamics (PD) of ATF936 and AXT914 in healthy male and female subjects.
- Phase B: A head-to-head comparison of ATF936 and AXT914, each given at its pharmacologically effective dose as determined in Phase A.
- Phase C: Similarity of PK/PD profile to single-dose profile after limited multiple dosing in healthy post-menopausal females. Early bone biomarker information after multiple dosing for best candidate as selected in Phase A or Phase B
