We have shown that αvß3 integrins control radioresistance, hypoxia and angiogenesis and that co-expression of FGF-2 and αvß3 integrins in the tumors of patients treated with exclusive radio-chemotherapy for stage III non-small lung carcinoma (NSCLC), was associated with a worse local control, suggesting that inhibition of αvß3 integrin could induce a radiosensitization of such tumours. We designed a phase I trial associating the specific αvß3/αvß5 integrin inhibitor cilengitide with radio-chemotherapy in patients with stage III NSCLC.


A standard 3 + 3 dose escalation design was used. Cilengitide was given in continuous infusion starting 2 weeks before and then during the whole course of the radio-chemotherapy (66 Gy combined with a Platine-Navelbine regimen), and then at a dose of 2000 mg twice a week in association with chemotherapy. Planed Cilengitide continuous infusion dose levels were 12, 18, 27 and 40 mg/h. PET-FDG and CT scan were performed before and then after the first two weeks of Cilengitide administration and then 2 months after the end of radio-chemotherapy. Patients were followed by CT scan. Toxicity for DLT was assessed during combined treatment and until 1 month after. Clinical response on CT scan and TEP was evaluated according to RECIST and PERCIST criteria.


Fourteen patients were included between March 2010 and July 2013. Eleven patients were evaluable for DLT. No DLT was observed at level 0, 1 and 2. One DLT, a tracheo-bronchial fistula was reported at the 40 mg/h dose. No relevant adverse event related to Cilengitide (7 grade 1 and one grade 2) was observed on the whole population. Among 11 patients evaluable for efficacy, 9 patients presented a partial response and 2 a stable disease. At 6 months after the end of radio-chemotherapy, 2 patients presented a progressive disease. At PET evaluation 2 months after radio-chemotherapy, 4 patients had a complete response and 4 patients had a partial response.


Cilengitide given continuously with radio-chemotherapy was well tolerated and shows encouraging clinical results, suggesting that targeting αvß3 integrin continuously during radio-chemotherapy in NSCLC is a promising approach to treat this disease.
