Clinical Trial Summary

The goal of the study was to compare and evaluate safety and efficacy of tesevatinib 50 milligrams (mg) versus placebo in participants with autosomal dominant polycystic kidney disease (ADPKD).

Description:

Safety and efficacy of 50 mg tesevatinib in comparison to placebo in participants with ADPKD was assessed.

The primary purpose of this study was focused on evaluating the change from Baseline in height-adjusted total kidney volume (htTKV) as measured by magnetic resonance imaging (MRI) at Months 12, 18, and 24, and 30 days post-dose in participants with ADPKD treated with tesevatinib or placebo.

If eligible for the study participation, participants were randomly assigned to either investigational treatment group or placebo group. Treatment group received 50 mg tesevatinib once daily for 24 months and control group received the placebo once daily for 24 months.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change From Baseline in Height Adjusted Total Kidney Volume (htTKV) at Month 12	htTKV was calculated using total kidney volume (in milliliters) obtained from magnetic resonance imaging (MRI) divided by height (in meters). Least square (LS) mean and standard error (SE) were estimated by using analysis of covariance (ANCOVA) model. Change from Baseline in htTKV at Month 12 was reported in this outcome measure.	Baseline (Day 1), Month 12
Primary	Change From Baseline in Height Adjusted Total Kidney Volume at Month 18	htTKV was calculated using total kidney volume (in milliliters) obtained from MRI divided by height (in meters). LS mean and SE were estimated by using ANCOVA model. Change from Baseline in htTKV at Month 18 was reported in this outcome measure.	Baseline (Day 1), Month 18
Primary	Change From Baseline in Height Adjusted Total Kidney Volume at Month 24	htTKV was calculated using total kidney volume (in milliliters) obtained from MRI divided by height (in meters). LS mean and SE were estimated by using ANCOVA model. Change from Baseline in htTKV at Month 24 was reported in this outcome measure.	Baseline (Day 1), Month 24
Primary	Change From Baseline in Height Adjusted Total Kidney Volume at End of Study	htTKV was calculated using total kidney volume (in milliliters) obtained from MRI divided by height (in meters). LS mean and SE were estimated by using ANCOVA model. Change from Baseline in htTKV at end of study (i.e., up to 26 months) was reported in this outcome measure.	Baseline (Day 1), End of study (anytime up to 26 months)
Secondary	Number of Participants With Treatment-emergent Adverse Events (TEAEs)	An adverse event (AE) was any untoward medical occurrence in a clinical study participant administered a medicinal product and which did not necessarily had to have a causal relationship with the treatment. TEAEs were AEs that developed or worsened or became serious from the first dose (Day 1) of the study drug until end of study.	From Baseline (Day 1) up to 30 days post last dose of study drug (i.e., up to 26 months)
Secondary	Change From Baseline in Estimated Glomerular Filtration Rate (eGFR) at Months 12, 18, 24 and End of Study	eGFR is a test for renal function. eGFR was calculated by using the 4-variable modification of diet in renal disease (MDRD-4) formula reported as milliliters per minute per 1.73 square meter (mL/min/1.73 m^2). LS mean and SE were estimated using ANCOVA model.	Baseline (Day 1), Months 12, 18, 24 and at end of study (i.e., anytime up to 26 months)
