Gilead Initiates Studies for New Once Daily, One Pill HIV Protease Inhibitor
 
 
  Gilead Files Investigational New Drug Application for Its Novel Protease Inhibitor; Anti-HIV Drug Developed Using Gilead's Proprietary Prodrug Technology
 
Press release from Gilead Sciences
 
FOSTER CITY, Calif.--(BUSINESS WIRE)--01/12/2004--Gilead Sciences, Inc. today announced that it has submitted an investigational new drug (IND) application to the U.S. Food & Drug Administration (FDA) to evaluate GS 9005 (formerly known as GS 4338) as a potential new therapy for HIV. Under this IND, Gilead plans to assess the oral bioavailability, pharmacokinetics, safety and efficacy of GS 9005 in healthy volunteers and HIV positive patients. GS 9005 is a novel HIV protease inhibitor (PI) discovered at Gilead. Based on data from preclinical and in vitro studies, GS 9005 has the potential to be dosed as a single pill once daily and may have a clinical resistance profile that is distinct from commercially-available drugs in the PI class.
 
GS 9005 utilizes the company's novel prodrug technology, which allows a drug to preferentially target lymphocytes, the primary site of HIV replication. This technology has been evaluated through the development of GS 7340, an investigational anti-HIV compound in Phase I/II development. GS 7340 is a prodrug of tenofovir, the active agent in the company's HIV drug Viread(R) (tenofovir disoproxil fumarate). Positive results from early clinical studies of GS 7340 provided the validation of this technology, which Gilead plans to apply to other HIV product candidates and drugs in other therapeutic categories that involve the lymphatic system.
 
"Although great progress has been made in the treatment of HIV, there is still a marked need for new therapeutics with the combined attributes of once-daily dosing, significant potency, improved long-term safety and activity against drug-resistant virus," said John C. Martin, PhD, President and Chief Executive Officer of Gilead Sciences, Inc. "We look forward to initiating clinical studies of GS 9005 and further advancing this important technology."
 
As an investigational compound, GS 9005 has not yet been determined safe or efficacious in humans for its ultimate intended use.
