A phase I study of the VEGFR kinase inhibitor vatalanib in combination with the mTOR inhibitor, everolimus, in patients with advanced solid tumors.

Purpose Combining small-molecule inhibitors of different targets was shown to be synergistic in preclinical studies. Testing this concept in clinical trials is, however, daunting due to challenges in toxicity management and efficacy assessment. This study attempted to evaluate the safety and efficacy of vatalanib plus everolimus in patients with advanced solid tumors and explore the utility of dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) studies as a predictive biomarker.

Up-regulation of pro-angiogenic factors and establishment of tolerance in malignant pleural effusions.

Introduction: Malignant pleural effusions (MPEs) are a significant source of cancer morbidity and mortality. Currently there is no cure for MPEs and treatments only palliate the symptoms. The purpose of this study was to determine if there are differences in markers of angiogenesis and immune phenotypes between adenocarcinoma-induced MPEs and benign pleural effusions (BPEs).

Phase 1 study of sorafenib in combination with bortezomib in patients with advanced malignancies.

Background: Sorafenib (a VEGFR and multi-targeted kinase inhibitor) and Bortezomib (a proteasome inhibitor) have clinical antineoplastic activities as single agents, and combine synergistically in preclinical models.

Methods: This Phase I study was undertaken to define the toxicity and the maximum tolerated doses (MTD) of the combination in patients with advanced solid tumors. Patients with cytologic or histologic proof of unresectable solid tumors were treated with escalating doses of sorafenib (twice daily) and bortezomib (days 1, 4, 8 and 11 intravenously) with 21-day cycles.

Is Age ≥ 70 Years an Important Predictor of Adverse Events Among Patients Enrolled in Metastatic Melanoma Trials? Findings from Pooled Analyses of Therapeutic Trials.

BACKGROUND: The current study was undertaken to explore whether older age predicts adverse event rates in metastatic melanoma patients participating in cancer clinical trials. METHODS: Six phase II studies conducted at our institution for patients with metastatic disease were used in these pooled analyses: 1) ABT-510; 2) bortezomib, paclitaxel, and carboplatin; 3) everolimus; 4) bevacizumab, paclitaxel, carboplatin; 5) carboplatin and abraxane; and 6) temozolomide and everolimus. In total, 233 patients, 64 elderly (≥ 70 years) and 169 younger, were analyzed for age-based differences in grade 2 or worse adverse events and other clinical outcomes.

Fluctuation of systemic immunity in melanoma and implications for timing of therapy.

Evidence suggests that immunological response in chronic inflammation is dynamic, oscillating between active immunity and tolerance. We hypothesized that a similar dynamic exists in melanoma and administration of therapy during a unique phase of such oscillation could impact clinical outcome. Patients with metastatic melanoma eligible to undergo temozolomide underwent serial measurements of C-reactive protein (CRP) and immune biomarkers every 2-3 days for 2 weeks before starting therapy.
