Gilead Sciences, Tibotec To Develop Second Once-Daily HIV Treatment
Foster City, Calif.-based Gilead Sciences on Thursday said it has entered into a license and collaboration agreement with Johnson and Johnson subsidiary Tibotec Pharmaceuticals for the development and commercialization of a new once-daily fixed-dose treatment for HIV, the San Francisco Business Times reports. The FDA approved the first once-daily HIV treatment Atripla in 2006 (7/16). The new antiretroviral drug would contain Tibotec"s experimental non-nucleoside reverse transcriptase inhibitor, known as TMC278, and Gilead"s combination pill, Truvada. Kevin Young, head of commercial operations at Gilead "said the new combination pill, along with Gilead"s experimental "quad" pill, will be used for newly-diagnosed patients, with physicians reluctant to change therapy for patients who are responding well to Atripla," Reuters reports. Young said the drug is expected to reach the market in 2011 (Beasley, 7/16).

Adolescent Obesity Study

Drs. Timothy Halliday and Sally Kwak, economics professors at the University of Hawaii at Manoa, recently published a paper in Economics and Human Biology titled, "Weight Gain in Adolescents and Their Peers." The article examines trends in adolescent body mass index (BMI) in a nationally representative dataset. In their study, Halliday and Kwak document strong correlations in weight gain between adolescents and their friends, even after controlling for confounding factors such as race, sex and age. While these correlations may be indicative of pupils causing their peers to gain weight, the authors provide evidence that a substantial part of the correlations is a consequence of sorting on BMI. In addition, they discuss many of the econometric issues in estimating such effects while accounting for growth spurts and difficulties in defining adolescent obesity. Halliday and Kwak discuss policy implications of such findings for school-based interventions to combat obesity. Their work contributes to a growing body of literature studying the impact of peers on student outcomes. Click here to view a copy of the abstract. Timothy Halliday University of Hawaii at Manoa
