Below is a look at some of the headlines for companies that made news in the healthcare sector on July 24, 2012.

Gilead Sciences, Inc. (Nasdaq: GILD) announced full clinical trial results from a pivotal Phase 3 study evaluating cobicistat, a pharmacoenhancing or “boosting” agent for HIV therapy, compared to ritonavir, which is currently the only agent used to boost certain antiretroviral treatment regimens. The study found that an HIV regimen containing a cobicistat-boosted protease inhibitor was non-inferior to a regimen containing a ritonavir-boosted protease inhibitor at 48 weeks of therapy. The findings will be presented today in an oral session (abstract #TUAB0103) at the 19th International AIDS Conference (AIDS 2012) taking place in Washington, D.C.

“These data demonstrate that cobicistat may be an effective option for boosting the potency of HIV regimens that are based on protease inhibitors,” said Joel Gallant, MD, MPH, Professor of Medicine and Epidemiology at Johns Hopkins University, and principal investigator of the study.

In the trial (Study 114), treatment-naïve adult patients received either cobicistat or ritonavir for 48 weeks. All patients also received atazanavir (a protease inhibitor) plus Truvada® (emtricitabine and tenofovir disoproxil fumarate). At 48 weeks, the study found that 85 percent of patients on the cobicistat-containing regimen compared to 87 percent of patients on the ritonavir-containing regimen achieved HIV RNA (viral load) levels less than 50 copies/mL, based on the U.S. Food and Drug Administration (FDA) snapshot algorithm (95 percent CI for the difference: -7.4 percent to +3.0 percent; predefined criterion for non-inferiority was a lower bound of a two-sided 95 percent CI of -12 percent). Twenty-five patients (7 percent) discontinued treatment due to adverse events in each arm of the study.



=====



Pfizer Inc. (NYSE:PFE), Johnson & Johnson (NYSE:JNJ)
and Elan (NYSE:ELN) experimental Alzheimer’s treatment failed to improve symptoms of dementia in the first of four pivotal studies testing the drug.

Bapineuzumab, designed to target the brain plaques that serve as a hallmark of Alzheimer’s, didn’t aid cognitive or functional ability in patients who carry a gene, called ApoE4, that makes them more likely to get the disease, Pfizer said yesterday in a statement. Doctors now await results from trials in patients without the higher genetic risk.

“There was no reason to believe, unless there was a miracle, that this would be positive,” said Rudolph Tanzi, professor of neurology at Harvard Medical School in Boston. “It will only be the results of the non-ApoE4 carriers that will inform us about the future.”

Bapineuzumab is in a race with a similar product from Indianapolis-based Eli Lilly & Co. (LLY) to become the first therapy to target a cause for Alzheimer’s, rather than just its symptoms. While patients in the failed study, dubbed 302, have now been taken off the drug, the other trials will continue, New York-based Pfizer said in its statement.

Elan fell 12 percent to 9.79 euros in Dublin trading, its largest one-day drop in two years. Pfizer fell 1 percent to $23.38 at 4 p.m. New York time, and J&J, based in New Brunswick, NJ, fell 1.1 percent to $67.35.
