          Abstract

          In this phase Ib study, four combination therapies of nivolumab 10 mg/kg and standard chemotherapy (cisplatin/gemcitabine, cisplatin/pemetrexed, carboplatin/paclitaxel/bevacizumab, or docetaxel) showed acceptable toxicity profiles in patients with advanced non-small-cell lung cancer. Furthermore, these combination therapies presented encouraging antitumor activities.

          Abstract

          Background

          The human IgG4 monoclonal antibody nivolumab targets programmed cell death-1 (PD-1) and promotes antitumor response by blocking the interaction of PD-1 with its ligands. This single-center phase Ib study investigated the tolerability, safety, and pharmacokinetics of nivolumab combined with standard chemotherapy in patients with advanced non-small-cell lung cancer (NSCLC).

          Patients and methods

          Patients who had stage IIIB without indication for definitive radiotherapy, stage IV, or recurrent NSCLC were eligible. Regimens were nivolumab 10 mg/kg + gemcitabine/cisplatin (arm A), pemetrexed/cisplatin (arm B), paclitaxel/carboplatin/bevacizumab (arm C), or docetaxel (arm D). Regimens A, B, and D were repeated every 3 weeks for up to four cycles and regimen C was repeated for up to six cycles; nivolumab alone (arm A), with pemetrexed (arm B), bevacizumab (arm C), or docetaxel (arm D) was continued every 3 weeks as maintenance therapy until disease progression or unacceptable toxicity. Dose-limiting toxicity (DLT) was evaluated during the first treatment cycle.

          Results

          As of March 2014, six patients were enrolled in each arm. The combination of nivolumab 10 mg/kg and chemotherapy was well tolerated. DLT was observed in only one patient in arm A (alanine aminotransferase increased). Select adverse events (those with a potential immunologic cause) of any grade were observed in six, four, six, and five patients in arms A, B, C, and D, respectively. Three, three, six, and one patient achieved partial response while median progression-free survival was 6.28, 9.63 months, not reached, and 3.15 months in arms A, B, C, and D, respectively.

          Conclusions

          Combination of nivolumab 10 mg/kg and chemotherapy showed an acceptable toxicity profile and encouraging antitumor activity in patients with advanced NSCLC.

          Cytokine Levels Correlate with Immune Cell Infiltration after Anti-VEGF Therapy in Preclinical Mouse Models of Breast Cancer

          The effect of blocking VEGF activity in solid tumors extends beyond inhibition of angiogenesis. However, no studies have compared the effectiveness of mechanistically different anti-VEGF inhibitors with respect to changes in tumor growth and alterations in the tumor microenvironment. In this study we use three distinct breast cancer models, a MDA-MB-231 xenograft model, a 4T1 syngenic model, and a transgenic model using MMTV-PyMT mice, to explore the effects of various anti-VEGF therapies on tumor vasculature, immune cell infiltration, and cytokine levels. Tumor vasculature and immune cell infiltration were evaluated using immunohistochemistry. Cytokine levels were evaluated using ELISA and electrochemiluminescence. We found that blocking the activation of VEGF receptor resulted in changes in intra-tumoral cytokine levels, specifically IL-1β, IL-6 and CXCL1. Modulation of the level these cytokines is important for controlling immune cell infiltration and ultimately tumor growth. Furthermore, we demonstrate that selective inhibition of VEGF binding to VEGFR2 with r84 is more effective at controlling tumor growth and inhibiting the infiltration of suppressive immune cells (MDSC, Treg, macrophages) while increasing the mature dendritic cell fraction than other anti-VEGF strategies. In addition, we found that changes in serum IL-1β and IL-6 levels correlated with response to therapy, identifying two possible biomarkers for assessing the effectiveness of anti-VEGF therapy in breast cancer patients.

              Randomized phase II study of first-line carboplatin-paclitaxel with or without bevacizumab in Japanese patients with advanced non-squamous non-small-cell lung cancer.

              This multicenter, randomized, open-label, phase II study (JO19907) compared the efficacy and safety of first-line carboplatin-paclitaxel (CP) alone with bevacizumab-CP in Japanese patients with advanced non-squamous non-small-cell lung cancer (NSCLC). Chemonaïve patients with stage IIIB, IV or recurrent non-squamous NSCLC were eligible for participation. Patients were randomly assigned in a 2:1 ratio to receive bevacizumab-CP or CP alone. Chemotherapy was repeated for up to 6 cycles or until disease progression or unacceptable toxicity. Bevacizumab recipients who completed ≥3 cycles of chemotherapy could continue bevacizumab as monotherapy until disease progression or unacceptable toxicity. The primary endpoint was progression-free survival (PFS). After confirming the tolerability of bevacizumab-CP in a small number of patients, 180 patients were recruited, of whom 121 were assigned to bevacizumab-CP and 59 to CP alone. Hazard ratio (HR) for PFS was 0.61 with bevacizumab-CP versus CP alone (p=0.0090; median 6.9 versus 5.9 months). Objective response rate was significantly higher with bevacizumab-CP than with CP alone (60.7% versus 31.0%; p=0.0013). Median overall survival was >22 months in both treatment groups (HR 0.99; p=0.9526). No new safety signals were detected. Study JO19907 met its primary endpoint, demonstrating that the addition of bevacizumab to first-line CP significantly improves PFS in Japanese patients with advanced non-squamous NSCLC. This prolonged PFS by bevacizumab did not translate into OS benefit with the extremely longer underlying survival compared to historical data. No new safety signals were identified in this population. (Japan Pharmaceutical Information Center [JAPIC] registration number: CTI-060338). Copyright © 2011 Elsevier Ireland Ltd.
