Trial of PI-88 With Docetaxel in Advanced Non-Small-Cell Lung Cancer (NSCLC)

Phase 2

Completed

• Conditions: Carcinoma, Non-Small-Cell Lung

• Registration Number: NCT00097851
• Lead Sponsor: Cellxpert Biotechnology Corp.

Brief Summary

PI-88 is a new experimental drug that inhibits tumour growth by reducing the formation of new blood vessels into tumours. Docetaxel is a standard second-line treatment offered to patients with non-small-cell lung cancer who haven't responded to first-line therapies (platinum-based drugs or radiotherapy). Of this group of patients, only 20% remain progression-free 6 months after starting docetaxel treatment. The PR88202 study has been designed to compare two different cancer treatments (docetaxel only, and docetaxel plus PI-88) and to work out which is more effective against the cancer. It is hoped that the combination of PI-88 with docetaxel will allow patients to extend the time it takes for their disease to progress, and also to improve their quality of life.

Detailed Description

PR88202 is an open-label randomized study. In the initial phase of the study, patients will be randomized to receive weekly docetaxel alone, or PI-88 in combination with weekly docetaxel. Both groups will receive docetaxel (30 mg/m2), administered by intravenous infusion on days 1, 8 and 15 of a 28-day cycle. The second group only will receive PI-88 (250 mg/day) in addition to docetaxel; PI-88 will be administered by subcutaneous injection on days 1-4, 8-11 and 15-18 of each cycle. The primary efficacy endpoint is the non-progression rate at 6 months. In the extension phase of the study, patients in the combination arm who have stable disease or an objective response after up to six treatment cycles will remain on PI-88 alone as maintenance therapy. Patients who initially receive docetaxel alone and who have disease progression or unacceptable toxicity before the completion of six cycles will be eligible to receive PI-88 alone as third-line therapy.
