Trial Outcomes & Findings for Erlotinib Before and After Surgery in Treating Patients With Muscle-Invasive Bladder Cancer (NCT NCT00380029)

NCT ID: NCT00380029

Last Updated: 2017-07-19

Results Overview

Determine the effect of neoadjuvant erlotinib hydrochloride on histopathological, molecular, and genetic correlates in patients undergoing radical cystectomy for muscle-invasive bladder cancer. Gene expression of pre-treatment and post-treatment tumor samples were analyzed to define molecular determinants of response or resistance to epidermal growth factor receptor (EGFR) inhibition. Both in vitro and in vivo EGFR-associated signatures were evaluated on pre-treatment bladder tumors. Candidate molecular determinants of sensitivity to EGFR inhibition were characterized and examined for their ability to predict sensitivity to EGFR inhibitors in vitro.

Measure
Erlotinib
erlotinib given before and after transurethral resection of a bladder tumor, TURBT Erlotinib: Erlotinib will be given at a dose of 150 mg per day for 4 weeks before undergoing planned radical cystectomy. In addition, patients will continue on erlotinib daily at a dose of 150 mg per day (qd dosing) for up to 2 years after surgery (beginning within 12 weeks of surgery) or until evidence of disease recurrence or progression Radical Cystectomy: Will occur 4 weeks prior to dosing with erlotinib

PRIMARY outcome

Timeframe: 4 weeks before treatment and 4 weeks post treatment

Population: Only patients with tumor samples with sufficient and high quality RNA were used to generate the in vivo signatures.

Determine the effect of neoadjuvant erlotinib hydrochloride on histopathological, molecular, and genetic correlates in patients undergoing radical cystectomy for muscle-invasive bladder cancer. Gene expression of pre-treatment and post-treatment tumor samples were analyzed to define molecular determinants of response or resistance to epidermal growth factor receptor (EGFR) inhibition. Both in vitro and in vivo EGFR-associated signatures were evaluated on pre-treatment bladder tumors. Candidate molecular determinants of sensitivity to EGFR inhibition were characterized and examined for their ability to predict sensitivity to EGFR inhibitors in vitro.

n=15 Participants
transurethral resection of a bladder tumor, (TURBT) tumors resected from participants treated with neo-adjuvant erlotinib which were considered to be not-downstaged ( pathologic stage at cystectomy \>=pT2 or node positive (N1 or N2))

Interval -0.61 to 0.75

SECONDARY outcome

Timeframe: 4 weeks

Determine the pathological complete response rate (P0 rate) after undergoing radical cystectomy (RC). Evaluated using Response Evaluation Criteria In Solid Tumors (RECIST). Complete Response (CR), Disappearance of all target lesions; Partial Response (PR), \>=30% decrease in the sum of the longest diameter of target lesions; Overall Response (OR) = CR + PR.
