3-Aminopyridine-2-carboxaldehyde thiosemicarbazone (3-AP), a new and potent inhibitor of ribonucleotide reductase (RR), increases the cellular uptake, DNA incorporation, and cytotoxicity of gemcitabine in tumor cell lines. A phase I trial was initiated to determine the safety profile and maximum tolerated doses of 3-AP and gemcitabine when used in(More)
Abnormal dendritic cell differentiation and accumulation of immature myeloid suppressor cells (ImC) is one of the major mechanisms of tumor escape. We tested the possibility of pharmacologic regulation of myeloid cell differentiation using all-trans-retinoic acid (ATRA). Eighteen patients with metastatic renal cell carcinoma were treated with ATRA followed(More)
BACKGROUND Population pharmacokinetic data suggest axitinib plasma exposure correlates with efficacy in metastatic renal-cell carcinoma. Axitinib dose titration might optimise exposure and improve outcomes. We prospectively assessed the efficacy and safety of axitinib dose titration in previously untreated patients with metastatic renal-cell carcinoma. (More)
Dendritic cells (DCs), a type of professional antigen-presenting cells, are responsible for initiation and maintenance of immune responses. Here we report that a substantial proportion of DCs in tumor-bearing mice and people with cancer have high amounts of triglycerides as compared with DCs from tumor-free mice and healthy individuals. In our studies,(More)
PURPOSE Myeloid-derived suppressor cells (MDSC) are one of the major factors responsible for immune suppression in cancer. Therefore, it would be important to identify effective therapeutic means to modulate these cells. EXPERIMENTAL DESIGN We evaluated the effect of the synthetic triterpenoid C-28 methyl ester of 2-cyano-3,12-dioxooleana-1,9,-dien-28-oic(More)
The assessment of health-related quality of life (HRQL) for patients with hormone-refractory prostate cancer (HRPC) is of paramount importance because new treatments have a modest impact on survival but side effects of treatment and disease symptoms can significantly impact HRQL. This was an observational, non-interventional, multi-center, multi-national(More)
BACKGROUND This study evaluated the tolerability and antitumor activity of AMG 386, a peptibody (a peptide Fc fusion) that neutralizes the interaction of angiopoietin-1 and angiopoietin-2 with Tie2 (tyrosine kinase with immunoglobulin-like and EGF-like domains 2), plus sorafenib in patients with clear cell metastatic renal cell carcinoma (mRCC) in a(More)
BACKGROUND Research has shown that self-directed stress management training improves mental well-being in patients undergoing chemotherapy. The present study extends this work by evaluating separate and combined effects of stress management training and home-based exercise. METHOD Following assessment of mental and physical well-being, depression,(More)
