VANRAFIA

Atrasentan area under the time concentration curve (AUC) is dose proportional across the 0.35 mg to 30 mg (0.47 to 40 times the approved recommended dosage) dose range. Atrasentan steady state plasma concentrations are reached within 7 days with 2- to 3-fold accumulation.

AbsorptionAtrasentan time to peak plasma concentration (T max ) is approximately 0.5 hour. Effect of Food No clinically significant differences in atrasentan pharmacokinetics were observed following administration with a high-...

14.1 IgA Nephropathy The effect of VANRAFIA on proteinuria was assessed in a randomized, double-blind, placebo-controlled, multicenter, global study (ALIGN, NCT04573478) in adults with biopsy-proven primary IgAN, an eGFR ≥ 30 mL/min/1.73 m 2 , and urine protein ≥ 1 g/day on a stable dose of maximally tolerated renin angiotensin system inhibitor. The study included two cohorts: a main cohort of 340 patients and an exploratory cohort of 64 patients who were also on a stable dose of sodium glucose co-transporter 2 inhibitor (SGLT2i) at baseline. Patients with chronic kidney disease due to another...

Pregnancy ( 4.1 ) Hypersensitivity ( 4.2 ) 4.1 Pregnancy Use of VANRAFIA is contraindicated in patients who are pregnant [see Dosage and Administration (2.1), Warnings and Precautions (5.1), Use in Specific Populations (8.1)] . 4.2 Hypersensitivity VANRAFIA is contraindicated in patients with a history of a hypersensitivity reaction to atrasentan or any component of the product.

Hepatotoxicity ( 5.2 ) Fluid Retention ( 5.3 ) Decreased Sperm Counts ( 5.4 , 8.3 ) 5.1 Embryo-Fetal Toxicity Based on data from animal reproduction studies, VANRAFIA may cause fetal harm when administered to a pregnant patient and is contraindicated during pregnancy. The available human data for endothelin receptor antagonists do not establish the presence or absence of major birth defects related to the use of VANRAFIA. Counsel patients who can become pregnant of the potential risk to a fetus....
