Detailed Narrative
Yeztugo Launch and HIV Prevention
Gilead achieved FDA approval for lenacapavir (Yeztugo) for twice-yearly HIV prevention in mid-June, marking a significant milestone. The launch has seen strong early execution, with the first prescription written within hours and the first dose administered within days. Unaided awareness among healthcare providers was 72% pre-launch, significantly higher than typical. The company aims for 75% access within 6 months and 90% within 12 months, supported by early J-code confirmation for October 1 and formulary wins in key states like California and Florida.
HIV Treatment Portfolio Strength
The HIV segment delivered robust 7% year-over-year growth, reaching $5.1 billion in sales, despite an anticipated $900 million impact from Medicare Part D redesign. Biktarvy sales grew 9% to $3.5 billion, expanding its U.S. market share to over 51%. Descovy sales surged 35% to $653 million, benefiting from increased awareness and unrestricted access in the growing PrEP market, which now exceeds 0.5 million active users.
Oncology Pipeline Advancements
Gilead announced positive Phase III results for Trodelvy from ASCENT-03 and ASCENT-04 studies in first-line metastatic triple-negative breast cancer (TNBC). Detailed data from ASCENT-04 showed an 11.2 months median progression-free survival with Trodelvy plus pembrolizumab, a 35% improvement. These results support a planned filing for full approval in the first-line setting, with a potential FDA decision in 2026, aiming to expand Trodelvy's reach to a patient population almost twice the size of the second-line setting.
Cell Therapy Progress and Challenges
Cell therapy sales were down 7% year-over-year to $485 million, facing competitive headwinds. However, sales were up 5% sequentially, and the company is making progress in reducing adoption barriers. Recent FDA changes removed the CAR T REMS program requirement and reduced patient proximity and driving restrictions, which are expected to improve patient quality of life and broader adoption. New real-world data at ASCO also supported the viability of outpatient administration for Yescarta.
Clinical Pipeline Depth
Beyond Yeztugo, Gilead's clinical pipeline remains active. In HIV, new Phase III trials include PURPOSE-365 (once-yearly lenacapavir for PrEP) and ARTISTRY-1 and ARTISTRY-2 (bictegravir/lenacapavir combination for treatment). The company also has multiple next-generation CAR T constructs in development, with pivotal data for anito-cel in multiple myeloma expected later this year, targeting a 2026 launch.
Financial Performance and Outlook
The strong first-half performance led to an increase in full-year 2025 guidance for product sales (excluding Veklury) to $27.3 billion-$27.7 billion and diluted EPS to $7.95-$8.25. This reflects robust HIV growth and encouraging momentum in Livdelzi and Trodelvy, partially offset by a reduction in Veklury sales expectations due to lower COVID-19 hospitalizations and softer cell therapy expectations.
