A Randomized, Partially Blinded, Phase II Study to Assess the Safety, Tolerability, and Efficacy of ZD6474 Alone or in Combinaiton With Paclitaxel and Carboplatin in Subjects With Previously Untreated Locally Advanced or Metastatic Non-Small Cell Lung Cancer (NSCLC)


OBJECTIVES:

Primary

- Determine the appropriate and tolerable dose of ZD6474 when given in combination with
paclitaxel and carboplatin in patients with previously untreated stage IIIB or IV or
recurrent non-small cell lung cancer. (Part I)

- Compare the efficacy of ZD6474 vs paclitaxel and carboplatin vs ZD6474 in combination
with paclitaxel and carboplatin, in terms of time to progression, in these patients.
(Part II)

Secondary

- Compare the pharmacokinetics of these regimens in these patients. (Part I)

- Compare the objective tumor response rate (complete response [CR] and partial response
[PR]) in patients treated with these regimens. (Part II)

- Compare disease control rates (CR, PR, and stable disease) in patients treated with
these regimens. (Part II)

- Compare the safety and tolerability of these regimens in these patients. (Part II)

- Compare the quality of life, symptom improvement, and WHO performance status of
patients treated with these regimens. (Part II)

- Compare the overall survival of patients treated with these regimens. (Part II)

- Compare the changes in plasma exposure of these regimens in these patients. (Part II)

- Correlate plasma exposure with safety and biological activity of these regimens in
these patients. (Part II)

OUTLINE: This is a 2-part, randomized, single-blind, open-label, multicenter study.

- Part 1 (safety run-in phase): Patients receive paclitaxel IV over 60-90 minutes* and
carboplatin IV over 30-60 minutes on day 1. Patients also receive oral ZD6474 once
daily on days 1-21*. Treatment repeats every 21 days for 6 courses. Patients achieving
a partial response (PR), complete response (CR), or stable disease (SD) after 6 courses
of therapy receive oral ZD6474 alone once daily in the absence of disease progression
or unacceptable toxicity.

NOTE: *During course 1, patients receive paclitaxel over 3 hours and ZD6474 on days 2-21.

A cohort of 10 patients receives ZD6474 at dose level 1. If it is determined that there are
no safety concerns with the administration of ZD6474 at dose level 1, a second cohort of 10
patients receives ZD6474 at dose level 2. Once the appropriate and tolerable dose is
determined, additional patients are accrued and entered into part 2 of the study.

- Part 2 (randomized phase): Patients are randomized to 1 of 3 treatment arms.

- Arm I: Patients receive oral ZD6474 once daily at the appropriate and tolerable
dose determined in part 1.

- Arm II: Patients receive oral ZD6474 once daily on days 1-21 and paclitaxel and
carboplatin as in part 1. Treatment repeats every 21 days for 6 courses. Patients
achieving a PR, CR, or SD after 6 courses of therapy receive oral ZD6474 alone
once daily.

- Arm III: Patients receive oral placebo once daily on days 1-21 and paclitaxel and
carboplatin as in part 1. Treatment repeats every 21 days for 6 courses. Patients
achieving a PR, CR, or SD after 6 courses of therapy receive oral placebo alone
once daily.

Treatment in all arms continues in the absence of disease progression or unacceptable
toxicity.

In both parts of the study, quality of life is assessed at baseline and on day 1 of each
course.

Patients are followed every six weeks for at least 2 years.

PROJECTED ACCRUAL: A total of 10-220 patients (10-20 for part I and 200 [100 for arm I, 50
for arm II, and 50 for arm III] for part II) will be accrued for this study.
