Clinical Trial Summary

Primary objective of the study's Safety run-in:

• To determine the maximum tolerated dose (MTD) of cilengitide in combination with cetuximab, and platinum-based chemotherapy (cisplatin/vinorelbine or cisplatin/gemcitabine).

Primary objective of the study's Randomization Part:

• To assess the efficacy of cilengitide in combination with cetuximab and platinum-based chemotherapy (cisplatin/vinorelbine or cisplatin/gemcitabine) compared to cetuximab and platinum-based chemotherapy alone in terms of progression-free survival (PFS) time.

Study design and plan:

This is a multicenter, open-label, randomized, controlled Phase II study with a safety run-in part in subjects with advanced non-small cell lung cancer (NSCLC).

During the safety run-in, the regimen was intensified stepwise by cohort (cilengitide intravenous [i.v.] 1000 milligram [mg] to 2000 mg twice a week) in a classical 3+3 subjects (for each platinum-based chemotherapy regimens separately) approach with predefined dose- and schedule reduction rules.

In the safety run-in 12 subjects were included and evaluated for safety and feasibility of different escalating doses of cilengitide administered twice weekly in combination with cetuximab, cisplatin and vinorelbine or gemcitabine.

After completion of the safety run-in, the randomized part will be started, during which all subjects will receive cetuximab and platinum-based chemotherapy (cisplatin/vinorelbine or cisplatin/gemcitabine).

Subjects will be centrally randomized on a 1:1 basis to either Group A or C; Group B will be closed with implementation of Amendment No. 4 (dated 20 December 2010):

• Group A: Cilengitide 2000 mg once weekly (Days 1, 8, and 15 of every 3-week chemotherapy cycle) in combination with cetuximab and platinum-based chemotherapy that will consist of the following:

• Cetuximab once weekly (Days 1, 8, and 15), plus cisplatin on Day 1 and vinorelbine on Days 1 and 8 of every 3-week chemotherapy cycle, or

• Cetuximab once weekly (Days 1, 8, and 15), plus cisplatin on Day 1 and gemcitabine on Days 1 and 8 of every 3-week chemotherapy cycle.

The decision which of the 2 chemotherapy regimens will be applied for a given subject is at the discretion of the treating investigator.

• Group B: Cilengitide 2000 mg twice weekly (Days 1, 4, 8, 11, 15, and 18 of every 3-week chemotherapy cycle) in combination with cetuximab and platinum-based chemotherapy as described for Group A.

Group B will be closed with implementation of Amendment No. 4 (global, dated 20 December 2010). Subjects randomized to Group B before implementation of Amendment No 4 will continue to be treated as planned.

• Group C: Cetuximab and platinum-based chemotherapy as described for Group A

Chemotherapy will be given until radiographically documented progressive disease (PD) or unacceptable toxicity but for no more than 6 cycles.

Cilengitide and cetuximab will be given until radiographically documented PD or unacceptable toxicity.

Randomization will be performed centrally using an interactive voice/web response system (IXRS). A stratified block randomization procedure will be employed using chosen first-line chemotherapy (cisplatin/vinorelbine versus cisplatin/gemcitabine) as stratification criterion.
