A Phase II Study of the Safety, Efficacy and Pharmacokinetics of VX-710 in Combination With Doxorubicin and Vincristine in Patients With Small Cell Lung Cancer (SCLC)

OBJECTIVES: I. Establish the safety of VX-710 in combination with doxorubicin and
vincristine in patients with recurrent small cell lung cancer. II. Characterize the plasma
pharmacokinetics of this regimen in these patients. III. Establish the ability of this
regimen to improve the response rate to chemotherapy in these patients who have relapsed on
front line therapy. IV. Evaluate the multidrug resistance profile of these patients in
response to this regimen.

OUTLINE: This is a multicenter study. Stage I: Patients receive VX-710 IV over 72 hours,
followed by doxorubicin IV and vincristine IV four hours after initial VX-710. Vincristine
is administered at half dose in the first 3-6 patients. If no more than 1 of 6 patients
experiences dose limiting toxicity in the half dose cohort, 3 additional patients receive
full dose vincristine. The maximum tolerated dose is defined as the dose preceeding that at
which 2 of 6 patients experience dose limiting toxicity. Stage II: Patients receive VX-710
IV over 72 hours, followed by doxorubicin IV and full dose vincristine IV four hours after
initial VX-710. Treatment continues for up to 6 courses every 3 weeks in the absence of
disease progression or unacceptable toxicity. Patients are followed every 3 months for up to
1 year.

PROJECTED ACCRUAL: A minimum of 35 and a maximum of 92 patients will be accrued for this
