Trial Outcomes & Findings for Lapatinib and Topotecan in Treating Patients With Ovarian Epithelial Cancer or Primary Peritoneal Cancer That Did Not Respond to Cisplatin or Carboplatin (NCT NCT00436644)

NCT ID: NCT00436644

Last Updated: 2014-04-16

Results Overview

Measurable disease patients: measureable disease is defined as at least one lesion whose longest diameter \>= 2cm with conventional techniques or \>=1cm with spiral CT * Confirmed tumor response (complete and partial) as measured by RECIST(Response Evaluation Criteria In Solid Tumors) criteria on 2 consecutive evaluations at least 4 weeks apart. * Confirmed tumor response is at least a 30% decrease in the sum of the longest diameter of target lesions and no new lesions. Non-measurable disease patients: * Decrement in CA125 by \> 50% * Improvement in other evaluable disease
