Vandetanib (Zactima) received full approval from the US Food and Drug Administration (FDA) today for adults with nonresectable or metastatic medullary thyroid cancer (MTC). Vandetanib was initially approved under the FDA's orphan drug program, making it the first medical treatment for MTC.
Following up the combination regimen of gemcitabine (Gemzar) and FOLFOX with drugs designed to boost the immune system significantly improved progression-free survival (PFS) in patients with advanced colorectal cancer. Pierpaolo Correale MD, PhD, Siena University School of Medicine, Italy, noted that the benefits observed in the experimental arm of the trial led a monitoring committee to halt the trial early. Preliminary data were reported at the 102nd annual meeting of the American Association for Cancer Research being held in Orlando, Florida.
Recruiting adults with cancer to take part in clinical trials is an ongoing challenge in the United States, but the growing number of studies for targeted therapeutics and the positive news emerging from these studies might help turn that around. Trials of targeted agents depend heavily on pharmacokinetic and pharmacodynamic testing to assess outcomes, prompting a team of researchers to investigate how willing patients are to undergo various testing procedures in the trial setting.
