A study published in 2014 showed that 0.75&nbsp;mg and 1.25&nbsp;mg of atrasentan reduced urinary albumin by 35 and 38% respectively with modest side effects. Patients also had decreased home blood pressures (but no change in office readings) decrease total cholesterol and LDL. Patients in the 1.25&nbsp;mg dose group had increased weight gain which was presumably due to increased edema and had to withdraw from the study more than the placebo or 0.75&nbsp;mg dose group.<ref>{{cite journal | vauthors = de Zeeuw D, Coll B, Andress D, Brennan JJ, Tang H, Houser M, Correa-Rotter R, Kohan D, Lambers Heerspink HJ, Makino H, Perkovic V, Pritchett Y, Remuzzi G, Tobe SW, Toto R, Viberti G, Parving HH | title = The endothelin antagonist atrasentan lowers residual albuminuria in patients with type 2 diabetic nephropathy | journal = Journal of the American Society of Nephrology | volume = 25 | issue = 5 | pages = 1083–93 | date = May 2014 | pmid = 24722445 | pmc = 4005314 | doi = 10.1681/ASN.2013080830 }}</ref>
