Glaxo Wellcome is offering an expanded access program for abacavir (Ziagen, formerly 1592) to HIV-positive patients who are not benefiting from their current combination therapy. In a dramatic departure from the usual entry criteria, the abacavir eligibility criteria require no specific CD4 cell count or viral load. To qualify, volunteers must be on a failing regimen, unable to tolerate standard therapies, and a physician must verify that another drug combination would not be viable. Patients are urged to switch to a regimen of at least two new drugs based on U.S. government treatment guidelines. Similar programs are available for the anti-HIV drugs efavirenz (Sustiva) and adefovir dipivoxil (Preveon). People using abacavir, a nucleoside analog, may experience side effects such as headache, nausea, and vomiting. If a hypersensitivity reaction develops, patients must stop the treatment. Taking the drug after experiencing an adverse reaction can be life threatening.

Adefovir (Preveon) is a new compound for treating HIV infection and presents no risk for developing cross resistance. Adefovir, at 125 mg/day, has created a 0.5 log decrease in viral load in 50 percent of patients tested. At 250 mg/day, the decreases are similar. Increases in CD4+ cells are also recorded. Adverse reactions from adefovir include nausea, diarrhea, weakness, headache, and pain; slight elevations in liver enzymes were also recorded in some subjects. At the 12th week of the study, patients also experienced drops in carnitine levels by 42 percent at 125 mg/day, and 62 percent at 250 mg/day. Overall, adefovir is determined to be better tolerated at 125 mg/day with no greater benefits derived at higher doses.

Adenovirus serotypes 4 (ADV-4) and 7 (ADV-7) are important causes of febrile acute respiratory disease (ARD) in US military recruits. Previously licensed vaccines, which effectively controlled adenovirus-associated ARD, are no longer available. In the Fall of 2004 we conducted this Phase 1 randomized, double-blind, placebo-controlled trial of the live, oral ADV-4 and ADV-7 vaccines made by a new manufacturer to assess their safety and immunogenicity. The adenovirus vaccines were administered orally together in a single dose to thirty subjects. Twenty eight additional subjects received placebo. Subjects were then observed for 8 weeks. The most commonly reported adverse events were nasal congestion (33%), cough (33%), sore throat (27%), headache (20%), abdominal pain (17%), arthralgia (13%), nausea (13%) and diarrhea (13%). None of these rates differed significantly from placebo. The duration of vaccine virus fecal shedding was 7-21 days. Seventy three percent of vaccine recipients seroconverted to ADV-4 (GMT 23.3) while 63% seroconverted to ADV-7 (GMT 51.1) by Day 28. The new ADV-4 and ADV-7 vaccines were safe and induced a good immune response in the study population. Expanded trials for safety and efficacy are in progress.
