Background: Molecularly targeted agents for non-small cell lung cancer (NSCLC) can provide similar efficacy to chemotherapy without chemotherapy-associated toxicities. Combining two agents with different modes of action could further increase the efficacy of these therapies. The TASK study evaluated the efficacy and safety of the epidermal growth factor receptor tyrosine kinase inhibitor erlotinib in combination with the anti-angiogenic agent bevacizumab as first-line therapy in unselected, advanced non-squamous NSCLC patients. Methods: Patients were recruited from December 2007 to September 2008. Planned sample size was 200 patients, a total of 124 patients were randomized. Patients were randomized using a minimization algorithm 1:1 to receive bevacizumab (iv 15. mg/kg day 1 of each 21-day cycle) plus chemotherapy (gemcitabine/cisplatin or carboplatin/paclitaxel standard doses, 4-6 cycles) (BC arm) or bevacizumab plus erlotinib (p.o. 150. mg/day; BE arm) until disease progression or unacceptable toxicity. The primary endpoint was progression-free survival (PFS). If the hazard ratio (HR) of PFS for BE relative to BC was above 1.25 at the pre-planned interim analysis in favor of BC, the study would be re-evaluated. Secondary endpoints included overall survival, response rate and safety. Results: All randomized patients (n= 63 BE; n= 61 BC) were evaluated for the efficacy analyses. At the updated interim analysis, median PFS was 18.4 weeks (95% confidence interval [CI] 17.0-25.1) versus 25.0 weeks (95% CI 20.6-[not reached]) for BE versus BC, respectively (HR for death or disease progression, BE relative to BC, 2.05, p= 0.0183). The incidence of death was 19% for BE treatment compared with 11.5% for BC treatment. The HR for PFS at the updated interim analysis was above 1.25, therefore patients on the BE arm were permitted to change arms or switch to another drug and the study was terminated. Adverse events reported were as expected. Conclusions: The TASK study did not show a benefit in terms of PFS for the combination of erlotinib with bevacizumab in unselected first-line advanced non-squamous NSCLC compared with chemotherapy plus bevacizumab. © 2013 The Authors.

Background: Metronomic oral vinorelbine could be a safe option for elderly patients with advanced non small cell lung cancer (NSCLC). Metronomic administration of chemotherapy leads to a cytostatic action shifting treatment target from cancer cell to tumor angiogenesis. Methods: 43 chemotherapy naive elderly (≥70 yrs) PS 0-2 patients with stage IIIB-IV NSCLC were prospectively recruited. Median age was 80 yrs (M/F 36/7) with predominantly squamous histology. PS distribution was 0-1(16)/2(27) with a median of 3 serious co-morbid illnesses. Study treatment consisted of oral vinorelbine 50mg three times weekly (Monday-Wednesday-Friday) continuously until disease progression, unacceptable toxicity or patient refusal. Primary endpoints were overall response rate (ORR), clinical benefit (CB - disease response plus disease stabilization >12 weeks) and safety. Health-related QoL (HRQoL) was also assessed with FACT-L V4 scoring questionnaire. We conducted an exploratory time-course analysis of VEGF and thrombospondin-1 (TSP1) serum levels in a subgroup of patients. Results: Patients received a median of 5 (range 1-21) cycles with a total of 272 cycles delivered. ORR was 18.6% with 7 partial and 1 complete responses; 17/43 experienced stable disease lasting more than 12 weeks leading to an overall CB of 58.1%. Median time to progression was 5 (range 2-21) and median overall survival 9 (range 3-29) months. Treatment was well tolerated with rare serious toxicity. Regardless of severity main toxicities observed were anemia in 44%, fatigue in 32.4%, and diarrhoea 10.5%. FACT-L v4 scores did not significantly vary during treatment. Baseline VEGF levels were lower and showed a rapid increase during treatment in non-responders pts only while TSP1 levels did not change. Conclusions: Metronomic oral vinorelbine is safe in elderly patients with advanced NSCLC with an interesting activity mainly consisting in long-term disease stabilization coupled with an optimal patient compliance (Eudra-CT 2010-018762-23, AIFA OSS on 26 February 2010). © 2015.
