Trial Outcomes & Findings for A Phase IIa. Open-label, Multicenter, Dose-escalation Study to Assess the Tolerability and Pharmacokinetics of ZD4054 (Zibotentan) Given Orally Once Daily in Subjects With Metastatic Prostate Cancer (NCT NCT00055471)

NCT ID: NCT00055471

Last Updated: 2012-10-31

Results Overview

DLT is defined as experiencing Common Toxicity Criteria (CTC) grade 3 or 4 headache with onset within 24 h of receiving ZD4054, CTC grade 2 rhinitis leading to the withdrawal of the subject, or other CTC grade 3 or 4 toxicity that was considered to be related to ZD4054 treatment. The numbers of patients with a DLT are reported.

Participant Flow

22 male patients with metastatic prostate cancer and rising Prostate Specific Antigen (PSA) levels were recruited from 11th June 2003 (last subject completed on 31st October 2005). This study was conducted in 2 centres in the United States.

6 of the 22 screened patients were not entered into the study as they did not fulfill the study eligibility criteria.
