The correlative analysis in this single arm, phase II study showed that those patients whose extent of vascular normalization was greater, had a longer duration of overall survival as well as progression-free survival, according to Jain. Median overall survival rate was 227 days; some patients lived for about two years and some lived less than two months.
"I was intrigued by the findings from this innovative trial, especially the fact that you could use separate biomarkers in combination to potentially predict the outcomes of patients," said Richard B. Gaynor, M.D., Ph.D., deputy editor of Cancer Research. Gaynor is the vice-president of cancer research at Eli Lilly and Company.
"This is really a severe disease and being able to determine response at such an early point is helpful to tailor treatment," he said. "If we can predict those responding to antiangiogenic therapy early on, we may be able to define where the benefit would be."
These findings need to be validated in larger, prospective studies. The researchers are currently conducting several studies based on these promising results in efforts to evaluate the benefits and prolonged survival of these patients.
One study is a phase III, randomized, multicenter, international trial that will compare patients treated with standard chemotherapy, those treated with cediranib, and those treated with a combination of the two to evaluate the effects and prolongation of life in all three cohorts. Approximately 300 patients are enrolled in this study, with enrollment halfway complete, ac
