| pubmed-article:12912943 | pubmed:abstractText | Evidence suggests that endothelin (ET)-1 and its primary receptor, the ET(A) receptor, may contribute to the progression of prostate and other cancers. Atrasentan (ABT-627) is a highly potent, selective ET(A) receptor antagonist. This study assessed safety, maximum tolerated dose, and pharmacokinetics (PK) in patients with refractory adenocarcinomas, primarily prostate cancer. Experimental Design: This 28-day, single-center Phase I trial evaluated the safety and PK of escalating oral atrasentan doses (2.5-95 mg) given daily (except day 2) to eligible patients >/==" BORDER="0">18 years old with an adenocarcinoma proven resistant to standard therapy. Priority was given to patients with hormone-refractory prostate cancer. After 28 days, patients without objective signs of tumor progression were eligible to continue atrasentan in an extension study. | lld:pubmed |
