A Phase I, Open-Label, Dose-Seeking Study of AZD2171 Given Daily Orally in Combination With Selected Standard Chemotherapy Regimens (CT) in Patients With Advanced Incurable Non-Small Cell Lung Cancer (NSCLC) or Colorectal Cancer

OBJECTIVES:

• Determine the recommended phase II dose of AZD2171 when administered with standard combination chemotherapy in patients with advanced non-small cell lung cancer or colorectal cancer.
• Determine the safety, tolerability, toxicity profile, dose-limiting toxicities, and pharmacokinetic profile of this treatment regimen.
• Assess the antitumor activity of this treatment regimen in patients with measurable disease.
• Correlate the toxicity profile with pharmacokinetics.

OUTLINE: This is a multicenter, open-label, dose-escalation study of AZD2171. Patients are assigned to 1 of 2 treatment groups according to disease.

• Group 1 (non-small cell lung cancer): Patients receive gemcitabine hydrochloride IV on days 1 and 8 and cisplatin IV on day 1. Patients also receive oral AZD2171 once daily beginning on day 2. Treatment repeats every 21 days in the absence of disease progression or unacceptable toxicity.
• Group 2 (colorectal cancer): Patients receive oxaliplatin IV over 2 hours and leucovorin calcium IV over 2 hours on day 1 and fluorouracil IV continuously over 46 hours on days 1 and 2. Patients also receive oral AZD2171 once daily beginning on day 3. Treatment repeats every 14 days in the absence of disease progression or unacceptable toxicity.

In both groups, cohorts of 3-6 patients receive escalating doses of AZD2171 until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which at least 2 of 6 patients experience dose-limiting toxicity.
