The future of drug development in oncology lies in identifying subsets of patients who will benefit from particular therapies, using predictive biomarkers. These technologies offer hope of enhancing the value of cancer medicines and reducing the size, cost and failure rates of clinical trials. However, examples of the failure of predictive biomarkers also(More)
PURPOSE Insulin-like growth factor-1 receptor (IGF-1R) mediates cellular processes in cancer and has been proposed as a therapeutic target. Dalotuzumab (MK-0646) is a humanized IgG1 monoclonal antibody that binds to IGF-1R preventing receptor activation. This study was designed to evaluate the safety and tolerability of dalotuzumab, determine the(More)
Carcinogenesis involves the acquisition of multiple genetic changes altering various cellular phenotypes. These changes occur within the fixed time period of a human lifespan, and mechanisms that accelerate this process are more likely to result in clinical cancers. Mutator mutations decrease genome stability and, hence, accelerate the accumulation of(More)
Whereas over 85% of human cancers are solid tumors, of the 8 monoclonal antibodies (mAbs) currently approved for cancer therapy, 25% are directed at solid tumor surface antigens (Ags). This shortfall may be due to barriers to achieving adequate exposure in solid tumors. Advancements in tumor biology, protein engineering, and theoretical modeling of(More)
PURPOSE HER3 is a key dimerization partner for other HER family members, and its expression is associated with poor prognosis. This first-in-human study of U3-1287 (NCT00730470), a fully human anti-HER3 monoclonal antibody, evaluated its safety, tolerability, and pharmacokinetics in patients with advanced solid tumor. EXPERIMENTAL DESIGN The study was(More)
A multicentre, randomised study was carried out in Europe, South Africa and North America to compare the activity and tolerability of oral versus intravenous (i.v.) topotecan in patients with relapsed epithelial ovarian cancer. Patients who had failed first-line therapy after one platinum-based regimen, which could have included a taxane, were randomised to(More)
Monoclonal antibodies are increasingly being used as protein therapeutics for cancer. They offer very specific binding to target molecules on the surface of cancer cells, relatively few side effects and predictable pharmacokinetics. Tumor shrinkage is seen in some patients, and an incremental improvement in survival occurs in the group. However, due to(More)
A demultiplexer is an electronic circuit designed to separate two or more combined signals. We report on a demultiplexer architecture for bridging from the submicrometer dimensions of lithographic patterning to the nanometer-scale dimensions that can be achieved through nanofabrication methods for the selective addressing of ultrahigh-density nanowire(More)
PURPOSE Aberrant Notch signaling has been implicated in the pathogenesis of many human cancers. MK-0752 is a potent, oral inhibitor of γ-secretase, an enzyme required for Notch pathway activation. Safety, maximum-tolerated dose, pharmacokinetics (PKs), pharmacodynamics, and preliminary antitumor efficacy were assessed in a phase I study of MK-0752. (More)
