Endeavor Biomedicines, Inc.57 enrolled

Overview

The purposes of this study are to: 1. evaluate potential interactions between taladegib (ENV-101) and current standard-of-care (SOC) therapies for idiopathic pulmonary fibrosis (IPF), including nintedanib and pirfenidone, and 2. more fully characterize the pharmacokinetics (PK) of taladegib (i.e., how the body absorbs, distributes, metabolizes and excretes taladegib). This study will enroll 4 cohorts (groups) of participants. Each cohort will experience a different duration of treatment and sequestering (being housed) at the clinical site, followed by a 14-day follow-up period for safety evaluation. The longest duration of treatment for any cohort is 30 days.

Outcomes

Primary Outcomes

Cohort 1: Taladegib (ENV-101) maximum blood concentration (Cmax) after administration alone and after coadministration with nintedanib

Time frame: Day 1 and Day 13

Cohort 1: Time of taladegib maximum blood concentration (Tmax) after administration alone and after coadministration with nintedanib

Time frame: Day 1 and Day 13

Cohort 1: Taladegib absorption to time t (AUC[0-t]) after administration alone and after coadministration with nintedanib

AUC\[0-t\] represents "area under the concentration-time curve" and measures the amount of drug that is present in the blood from the time of administration to a given time t

Time frame: Day 1 and Day 13

Cohort 1: Taladegib total absorption (AUC[0-infinity]) after administration alone and after coadministration with nintedanib

Time frame: Day 1 and Day 13

Cohort 1: Taladegib extrapolated total absorption (AUC[extrapolated]) after administration alone and after coadministration with nintedanib

Time frame: Day 1 and Day 13

Cohort 1: Taladegib half-life in the blood (T1/2) after administration alone and after coadministration with nintedanib

Time frame: Day 1 and Day 13

Cohort 1: Elimination rate constant (K[el]) for taladegib after administration alone and after coadministration with nintedanib

K\[el\] represents the fraction of a drug that is removed from the body per unit of time.

Time frame: Day 1 and Day 13

Cohort 1: Apparent oral clearance (CL/F) of taladegib after administration alone and after coadministration with nintedanib

Apparent oral clearance represents the volume of plasma cleared of drug per unit time after oral administration.
