Video: Phase III Study Data With Vandetanib (Zactima(TM)) in Patients With Advanced Non-Small Cell Lung Cancer (NSCLC) Presented at American Society of Clinica...(erlotinib for PFS and OS (PFS: hazard ra...),Health

Date:5/30/2009

erlotinib for PFS and OS (PFS: hazard ratio [HR] 0.98, 95.22% CI 0.87-1.10; P=0.721; OS: HR 1.01, 95.08% CI 0.89-1.16; P=0.830). Objective response rate and symptom control were also similar for both treatments (ORR: both 12%; symptoms: pain, HR 0.96, P=0.583; dyspnea, HR 1.08, P=0.333; cough, HR 0.94, P=0.403).

The ZEST study was a randomized, double-blind, Phase III study evaluating the efficacy of vandetanib 300mg versus erlotinib 150mg. The study enrolled 1240 patients with locally advanced or metastatic NSCLC after failure of at least one prior anti-cancer therapy.

The most common adverse events observed in the ZEST study were rash, diarrhea and hypertension. Incidence of protocol-defined QTc prolongation was 5.1 percent in the vandetanib arm.

AstraZeneca plans to submit a regulatory submission for the use of vandetanib 100mg in combination with chemotherapy for patients with advanced NSCLC in the first half of 2009.

Evaluation of vandetanib is ongoing, as monotherapy or in combination with other anti-cancer therapies in a range of tumor types, including thyroid cancer.

Results from the ZEPHYR (300mg monotherapy study in EGFR failures in advanced NSCLC, Phase III) and ZETA (300 mg monotherapy in advanced medullary thyroid cancer, Phase III) studies will be available during the second half of 2009.
