FOSTER CITY, Calif.--(BUSINESS WIRE)-- Gilead Sciences, Inc. (Nasdaq: GILD) today announced its upcoming contributions to the 12th International AIDS Society Conference on HIV Science (IAS 2023), taking place in Brisbane, Australia, and virtually, from July 23-26, 2023. As the leader in HIV innovation, Gilead will provide updates on its signature initiatives and key collaborations while sharing new scientific data from its research and development programs. The breadth of data presented at the meeting, along with Gilead-led symposia, reflect its innovative approach to advancing HIV prevention, treatment and cure strategies and underscore Gilead’s focus on forming partnerships with communities worldwide as part of its unequivocal commitment to help end the HIV epidemic for everyone, everywhere.

“HIV will remain a global epidemic so long as people and communities do not have access to HIV care, services and innovative and life-saving medicines due to structural and social inequalities,” said Alex Kalomparis, Senior Vice President, Public Affairs, Gilead Sciences. “At Gilead, our efforts at the global, national and local levels aim to reduce these disparities, with an emphasis on eliminating stigma and discrimination, ensuring equitable access to people-centered HIV care and services, and forging industry-leading partnerships that expand global access to our innovative and life-saving medicines. During IAS 2023, we look forward to sharing the latest from our ongoing health equity efforts and launching a new community-based initiative that seeks to change the future of the HIV epidemic.”

Advancing Efforts to Address Barriers to HIV Care and Prevention

At IAS 2023, Gilead will convene two symposia to discuss the latest progress in policies and practical solutions from around the world to help achieve more equitable access to HIV care and services.

Ignite change: Championing HIV status-neutral care together (July 23, 3:00pm AEST), will feature an international multidisciplinary expert panel exploring how a status-neutral approach can improve care and help eliminate structural stigma; discuss steps to close the gaps in the care continuum; and consider what long-term success means for people living with HIV.

A second symposium, titled The Fire Within Us: Driven by Our Collective Passion to End the HIV Epidemic (July 24, 8:00am AEST), will highlight ongoing programs working to integrate patient-centered approaches across the HIV care continuum to improve access and care. The discussion will feature insights from a diverse panel on practical, person-centered solutions, which aim to enhance healthcare for everyone affected by HIV.

RADIAN®, a collaboration between Gilead and the Elton John AIDS Foundation, is hosting the forum; Eastern Europe and Central Asia in Crisis: Community-led strategies to leave no one behind and end the rapidly growing HIV epidemictaking place on July 24 at 6:30 p.m. AEST.

Driving Transformational Innovation in HIV Research

Gilead is committed to continuous scientific discovery to meet the evolving needs of people affected by HIV. At IAS 2023, Gilead will share new findings on HIV treatment and prevention strategies, as well as the latest updates from the company’s continued pursuit of an HIV cure.

“At Gilead, our person-centered approach to developing novel medicines aims to generate findings that are meaningful and beneficial to the people and communities confronting the day-to-day realities of HIV,” said Jared Baeten, MD, PhD, Vice President, HIV Clinical Development, Gilead Sciences. “Collaboration with researchers and community stakeholders, particularly those living with HIV or those who could benefit from PrEP, is integral to all aspects of Gilead’s scientific discovery process and is essential to realizing the transformative potential impact of our innovations. IAS 2023 is an invaluable opportunity to interact directly with the broad HIV community and help further our HIV research and development efforts.”

As part of the company’s ongoing effort to advance treatment research in communities with diverse health needs, Gilead will present results from studies evaluating Biktarvy® (bictegravir 50 mg/emtricitabine 200 mg/tenofovir alafenamide 25 mg tablets, B/F/TAF) in women with HIV who are pregnant and virologically suppressed and TAF-containing regimens in virologically suppressed children with HIV. Additional presentations from Gilead’s HIV treatment research program will include new 96-week findings from ALLIANCE, an ongoing Phase III trial evaluating the efficacy and safety profile of Biktarvy versus dolutegravir 50 mg (DTG) + emtricitabine 200 mg/tenofovir disoproxil fumarate 300 mg, F/TDF, DTG+F/TDF, in adults with HIV/HBV co-infection initiating treatment.

Additionally, outcomes from multiple studies evaluating lenacapavir, Gilead’s first-in-class, long-acting HIV-1 capsid inhibitor will be presented. The latest findings will highlight patient-reported outcomes from CAPELLA, which is an ongoing Phase 2/3 registrational study designed to evaluate the antiviral activity of twice-yearly lenacapavir administered as a subcutaneous injection in heavily treatment-experienced people with multi-drug resistant HIV-1 infection. Research will also be presented on the efficacy and safety profile of temporary oral bridging with lenacapavir when the administration of subcutaneous lenacapavir was interrupted.

Insights from Gilead’s cure research program include new data evaluating broadly neutralizing antibodies and the maintenance of virologic control in the absence of antiretroviral therapy.

Gilead scientists will also contribute to three IAS-hosted satellite sessions to further advance scientific dialogue on key issues including:

Please see below for U.S. Indication and Important Safety Information, including Boxed Warning, for Biktarvy. Please also see below for the U.S. Indication and Important Safety Information for Sunlenca®.

There is currently no cure for HIV or AIDS.

About Biktarvy

Biktarvy is a complete HIV treatment that combines three powerful medicines to form the smallest 3-drug, integrase strand transfer inhibitor (INSTI)-based single-tablet regimen (STR) available, offering simple once-daily dosing with or without food, with a limited drug interaction potential and a high barrier to resistance. Biktarvy combines the novel, unboosted INSTI bictegravir, with the Descovy® (emtricitabine 200 mg/tenofovir alafenamide 25 mg tablets, F/TAF) backbone. Biktarvy is a complete STR and should not be taken with other HIV medicines.

About Sunlenca

Sunlenca (300 mg tablet and 463.5 mg/1.5 mL injection) [(lenacapavir)] is a first-in-class, long-acting HIV capsid inhibitor approved in Australia, Canada, the European Union, Israel, Switzerland, the United Arab Emirates the United Kingdom and the United States for the treatment of HIV infection, in combination with other antiretroviral(s), in people with multi-drug resistant HIV who are heavily treatment-experienced. Sunlenca is the only HIV treatment option administered twice-yearly. Sunlenca tablets are approved for oral loading during initiation of Sunlenca treatment, prior to or at the time of the first long-acting lenacapavir injection depending on initiation option. The multi-stage mechanism of action of Sunlenca’s active pharmaceutical agent, lenacapavir, is distinguishable from other currently approved classes of antiviral agents. While most antivirals act on just one stage of viral replication, Sunlenca is designed to inhibit HIV at multiple stages of its lifecycle and has no known cross resistance exhibited in vitro to other existing drug classes.

Lenacapavir is being evaluated as a long-acting option in multiple ongoing and planned early and late-stage clinical studies in Gilead's prevention and treatment research program. Lenacapavir is being developed as a foundation for future HIV therapies with the goal of offering both long-acting oral and injectable options with several dosing frequencies, in combination or as a mono agent, that help address individual patient needs and preferences.

U.S. Indication for Biktarvy

Biktarvy is indicated as a complete regimen for the treatment of human immunodeficiency virus type 1 (HIV-1) infection in adults and pediatric patients weighing at least 14 kg who have no antiretroviral treatment history or to replace the current antiretroviral regimen in those who are virologically-suppressed (HIV-1 RNA less than 50 copies per mL) on a stable antiretroviral regimen with no history of treatment failure and no known substitutions associated with resistance to the individual components of Biktarvy.
