Trial Outcomes & Findings for Erlotinib Hydrochloride in Treating Participants With Muscle Invasive or Recurrent Urothelial Cancer (NCT NCT00749892)

NCT ID: NCT00749892

Last Updated: 2020-09-10

Results Overview

The response rate is the number of patients with urothelial cancer treated with erlotinib prior to cystectomy. The response is defined as the absence of residual cancer in the surgical removed tissue (i.e., pT0). A responder is defined as a participant with the pathological stage of pT0 meaning that there is no evidence of disease.

Participant Flow

Recruitment began 6/9/2008 and concluded on 12/19/2011 in the medical clinic. Diagnosis of invasive transitional cell carcinoma in the bladder, upper tract or urethra tumors were required for participants who were candidates for cystectomy to be considered. Participants with high-risk features were generally excluded.

Erlotinib treatment milestone: Three participants decided to not start the study medication.

PRIMARY outcome

Timeframe: Determined at the time of surgery or cystectomy

Population: two participants did not take any eroltinib and three participants stopped erlotinib early due to intolerable side effects.

The response rate is the number of patients with urothelial cancer treated with erlotinib prior to cystectomy. The response is defined as the absence of residual cancer in the surgical removed tissue (i.e., pT0). A responder is defined as a participant with the pathological stage of pT0 meaning that there is no evidence of disease.
