RESUMO
INTRODUCTION: Immunotherapy has become a promising approach for the treatment of NSCLC. In order to stimulate the host immune system against tumour antigens, several cancer vaccines have been generated and evaluated. Belagenpumatucel-L is a whole tumour cell vaccine expressing the antisense strand of the TGF-ß2 gene. AREAS COVERED: The purpose of this article is to review the most relevant findings of clinical trials testing belagenpumatucel-L in advanced NSCLC patients. EXPERT OPINION: Although the Phase III trial investigating belagenpumatucel-L in stage III/IV patients did not meet its primary end point, a survival benefit was observed in several subgroups of patients. Further studies are needed in order to select patients who may benefit from this vaccine.

INTRODUCTION: Originally formulated as an intravenous (i.v.) agent, vinorelbine is also currently available as an oral chemotherapeutic agent. Oral vinorelbine has demonstrated significant activity in different settings for NSCLC, including adjuvant treatment for resected disease, concurrent chemoradiation for locally advanced NSCLC and palliative chemotherapy for recurrent/metastatic NSCLC, as part of combination schedules or as a single-agent treatment. AREAS COVERED: The authors explored the available data describing the use of oral vinorelbine in NSCLC. PubMed articles and abstracts presented at international conferences were analysed, and relevant trials were reported and discussed. Specific settings, including the treatment of elderly and unfit patients and metronomic schedules including oral vinorelbine, were evaluated. Available pharmacoeconomic data were also assessed. EXPERT OPINION: Oral vinorelbine is an appealing agent, particularly as part of combination regimens containing platinum derivatives, although it can have a role as a single-agent treatment as well. Its safety profile is generally favourable and its route of administration is generally preferred by patients receiving chemotherapy. Compared to i.v. vinorelbine and other antineoplastic agents, oral vinorelbine has been reported to be advantageous in terms of cost savings.
