ABSTRACT: To determine the efficacy of the addition of gefitinib to raltitrexed in patients with colorectal cancer (CRC) that have progressed after first line chemotherapy. The study also sought to explore the safety of the combination and to investigate biomarkers predictive outcome. A total of 76 patients were randomized to raltitrexed (3 mg/m(2) i.v.) every 21 days plus either daily gefitinib (250 mg p.o.) or placebo. The primary endpoint of the study was progression free survival (PFS). Tumor tissues were collected to determine the expression of EGFR, pEGFR, pMAPK, and pAkt. Both groups were well balanced with regard to prognostic factors. Treatment was well tolerated with no increased in toxicity except diarrhea and skin rash in the combination group. There were no differences in PFS between the combination arm [63 days (95% CI: 57-84)] compared to the raltitrexed alone arm [72 days (95% CI: 59-132)], or overall survival 361 days (95% CI: 283-533 days) versus 291 days (95% CI: 255-539 days) respectively. The objective response rate was 7.9% (3 patients) (CI 95%: 1,66-21,38) versus 5.3% (2 patients) (CI 0,64-17,75), respectively. The biomarker studies were not conclusive. The combination of raltitrexed and gefitinib was well tolerated although was not associated with improved progression free survival in patients with refractory CRC.Investigational New Drugs 03/2010; 29(5):1038-44. · 3.36 Impact Factor -
Article: Novel therapeutic approaches to the treatment of metastatic breast cancer.
[show abstract] [hide abstract]
ABSTRACT: Metastatic breast cancer is ultimately an incurable disease, although recent data have shown that its incidence is decreasing and that patients with metastatic breast cancer live longer. This improvement in survival seems to be linked with the introduction of new therapeutic agents, novel combinations of existing therapies and targeted therapies. Our increasing understanding of the molecular biology of metastatic disease has allowed the development of therapies aimed at specific molecular targets. Some of these have already been approved for the treatment of metastatic breast cancer in combination with cytotoxics, and others have shown promising results regarding disease-free survival, overall response rates and time to disease progression. Given the enormous amount of information about drug discovery in cancer, it is important to be familiar with the present state of the treatment of metastatic breast cancer. The purpose of this review is to provide an update on the development of some of the most promising novel agents and treatment strategies in metastatic breast cancer.Cancer treatment reviews 10/2009; 36(1):33-42. · 5.30 Impact Factor
