safety and efficacy study of abraxane as maintenance treatment after abraxane plus carboplatin in 1st line stage iiib / iv squamous cell non-small cell lung cancer

Conditions: Squamous Cell Carcinoma, Non-Small-Cell Lung

Summary: maintenance treatment of advanced stage squamous cell nsclc. phase iii, randomized, open-label, multi-center study of nab-paclitaxel with best supportive care (bsc) or bsc alone as maintenance treatment after response or stable disease (sd) with nab-paclitaxel plus carboplatin as induction in subjects with stage iiib/iv squamous cell nsclc. subjects who discontinued treatment from the maintenance part for any reason other than withdrawal of consent, lost to follow-up, or death, were entered into a follow-up period that had a visit 28 days after progression or discontinuation. those who entered follow-up without progression continued with follow-up scans according to standard of care (soc) until documentation of progression of disease. additionally, subjects were followed for os by phone approximately every 90 days for a minimum of 18 months, for up to approximately 5 years after the last subject was randomized.
