Investigational Drug Cediranib Shows Promise in Patients With Recurrent Glioblastoma

Investigational Drug Cediranib Shows Promise in Patients With Recurrent Glioblastoma

Data for the investigational agent cediranib (AZD2171) were presented at the annual meeting of the American Society of Clinical Oncology (ASCO) from a phase II monotherapy study in patients with recurrent glioblastoma, the most aggressive form of primary brain tumor, with a high unmet medical need.

Results from the National Cancer Institute (NCI)-sponsored study at the Massachusetts General Hospital Cancer Center showed that 8 (27.6%) of the 31 patients with recurrent glioblastoma treated with cediranib, were alive and progression-free at 6 months. The dose-limiting toxicities most commonly observed in this study included hypertension, fatigue, and diarrhea.

Cediranib is a selective vascular endothelial growth factor (VEGF)-signaling inhibitor that targets all three VEGF receptors. The drug is currently in phase II/III development for advanced non-small-cell lung cancer (NSCLC) and advanced colorectal cancer as well as being investigated as part of a wide-ranging signal search program in other tumors such as glioblastoma.

"These encouraging data showing effects on progression-free survival warrant further investigation," commented Dr. Tracy Batchelor, chief of Neuro-Oncology at the Massachusetts General Hospital Cancer Center, associate professor of neurology at Harvard Medical School, and lead author of the phase II study.

Added Benefit

"In addition, cediranib alleviated brain swelling (edema) in many patients. Edema is a debilitating symptom in many brain cancer patients and is currently treated with steroids, which can carry their own debilitating side effects. Based on the first 16 patients, a steroid-sparing effect was demonstrated in most patients and was associated with the normalization of tumor vessels. This normalization might help to secure delivery and improve effectiveness of other therapeutic techniques such as chemotherapy drugs and radiation therapy," Dr. Batchelor said.

"The prognosis for recurrent glioblastoma patients is poor," commented AstraZeneca's Dr. Nick Botwood, global medical director for cediranib. "These are promising phase II results, and discussions are ongoing with Dr. Tracy Batchelor and his group regarding a confirmatory study in recurrent glioblastoma."

Phase II Study in Metastatic Renal Cell Carcinoma

Another ongoing NCI-sponsored cediranib phase II study, presented at ASCO 2007 by investigators from the Princess Margaret Hospital in Toronto, Canada, looked at cediranib in first-line, progressive, unresectable, advanced metastatic renal cell carcinoma.
