THE FIFTEEN-SECOND READ

GILD and MRK both describe HIV as an active growth and innovation engine rather than a mature category. GILD points to current momentum, with Q1 2025 HIV sales up 6% and Biktarvy up 7%, and is counting on the June 19 PDUFA date for twice yearly lenacapavir for PrEP to extend leadership into prevention amid 16% US PrEP market growth [m2392, m2393, m2395, m2406, m2407, m2421]. GILD also lays out a long horizon commitment of up to nine potential HIV products before 2033 with no major LOEs in that window [m2396, m2399]. MRK diverges by targeting the treatment backbone itself, positioning doravirine plus enzlotrovir as the first two-drug regimen without an integrase inhibitor to match Biktarvy's efficacy, and broadening enzlotrovir into an anchor medicine for multiple two-drug daily and weekly regimens alongside islatravir's novel translocation inhibition mechanism [m2194, m2449, m2458]. The clearest divergence is strategic: GILD is defending and extending its three-drug Biktarvy and PrEP franchise, while MRK is explicitly building toward a non-integrase-inhibitor, Insty-free two-drug future [m2194, m2459].

O'Day said HIV drove Q1 2025 growth, with base business up 4% and HIV sales up 6% year over year, Biktarvy up 7%. [m2392, m2393] O'Day reaffirmed the June 19 PDUFA date for twice-yearly lenacapavir for PrEP, with potential US launch immediately following. [m2395] Mercier and O'Day framed lenacapavir for PrEP as well positioned amid 16% US PrEP market growth and rising prevention awareness ahead of launch. [m2406, m2407, m2421] O'Day set a longer term goal of up to nine potential HIV products before the end of 2033, with no major LOEs until then. [m2396, m2399]

That's very insightful. Right? We are currently looking into the different study designs, right? We have not commented exactly on what we're planning on doing at this point in time. But you're absolutely right, there are different study designs that you can utilize and potentially a PK-based approach is a possibility that we're discussing.

#m2392 · 2025-04-24 · Daniel O'Day · STATED · by first quarter 2025

Our base business, excluding Veclury, grew 4% from the first quarter of 2024, primarily driven by growth in our HIV business.

#m2393 · 2025-04-24 · Daniel O'Day · STATED

HIV sales were up 6% year over year, with Biktarvy up 7%, highlighting our demand-led volume growth that was offset in part by the expected headwinds associated with the Part D redesign.

#m2395 · 2025-04-24 · Daniel O'Day · STATED · by June 19

In HIV, we are now only weeks away from the anticipated FDA decision on twice-yearly lenacapavir for PrEP. We remain on track for the June 19 PDUFA date with the potential launch in the US immediately following.

#m2396 · 2025-04-24 · Daniel O'Day · STATED · by before end of 2033

As a reminder, this is one of up to nine potential HIV products we are targeting before the end of 2033, building on Gilead Sciences, Inc.'s decades of leadership in HIV innovation.

#m2399 · 2025-04-24 · Daniel O'Day · STATED · by until end of 2033

As a reminder, we have no major LOEs until the end of 2033 and expect to drive top-line growth over time across all three of our therapeutic focus areas of virology, oncology, and inflammation.

#m2405 · 2025-04-24 · Johanna Mercier · STATED

Overall, the HIV treatment market continues to grow in line with our expectations, of 23% annually.

#m2406 · 2025-04-24 · Johanna Mercier · STATED

HIV prevention continues to represent the significant majority of Descovy sales, and growth this quarter was driven by broader awareness, growing unrestricted access, and associated pricing favorability, as well as focused commercial execution that contributed to approximately 16% US PrEP market growth year over year.

#m2407 · 2025-04-24 · Johanna Mercier · STATED

Growing awareness and adoption of HIV prevention is encouraging ahead of our upcoming potential US launch of lenacapavir for PrEP.

#m2408 · 2025-04-24 · Johanna Mercier · STATED

Building on our deep expertise and success of HIV launches and with strong engagement across the board from community leaders to healthcare providers, our teams are ready to build awareness, drive adoption, and overall, deliver a seamless customer experience.

#m2414 · 2025-04-24 · Dietmar Berger · STATED

Lenacapavir plus BNABs has already received breakthrough therapy designation from FDA, and these phase two data further underscore the potential for this combination to be the first complete twice-yearly treatment regimen for virologically suppressed people with HIV.

#m2421 · 2025-04-24 · Daniel O'Day · STATED

We think that LEN for PrEP is really well positioned there.

#m2425 · 2025-04-24 · Johanna Mercier · STATED · by next six to twelve months

We do believe though that despite this, we feel we're incredibly well-positioned because of the transformative nature of lenacapavir to build access across the different channels that and we're prepared to do that.

#m2426 · 2025-04-24 · Johanna Mercier · STATED · by next ten years

Think that number will definitely continue to grow quite rapidly, especially with the acceleration. I think it will accelerate with the launch of lenacapavir and I think that number could be quite exponential as you think about the next ten years or so.

MRK4 statements

Dr. Dean Li stated that doravirine plus enzlotrovir was the first complete two-drug regimen without an integrase inhibitor to match Biktarvy's three-drug efficacy and safety. [m2194] Dean Y. Li later broadened the ambition, stating ezlotrovir could serve as a novel anchor medicine across multiple two-drug regimens, offering both daily and weekly options. [m2194, m2449] Dean Y. Li also highlighted islatravir as a next-generation nucleoside analog with a unique translocation inhibition mechanism giving high potency and resistance barrier. [m2458] Dean Y. Li stated there will be excitement around a two-drug combo without an Insty backbone, reinforcing the non-integrase-inhibitor strategy first noted in 2025. [m2194, m2459]

#m2194 · 2025-04-24 · Dr. Dean Li · STATED

The combinations of doravirine and enzlotrovir is the first complete two-drug regimen without an integrase strand transfer inhibitor to demonstrate comparable efficacy and safety to the three-drug insti-based regimen Biktarvy.

#m2449 · 2026-02-03 · Dean Y. Li · STATED

Based on its potent antiviral properties and barrier to resistance, it is our ambition that ezlotrovir will serve as a novel anchor medicine across multiple two-drug treatment regimens, providing new daily and weekly options for people living with HIV.

#m2458 · 2026-02-03 · Dean Y. Li · STATED

So as you highlight, we are really excited about islatravir because we really think it is a next-generation nucleoside analog. So it leverages a unique mechanism of translocation inhibition that gives it high potency and a high degree of resistance.

#m2459 · 2026-02-03 · Dean Y. Li · STATED

I think there will be an excitement of having a two-drug combo without an Insty backbone.

OPEN is an unresolved commitment on the clock; STATED is on the record without a checkable bar and is never counted or scored. Method: methodology.
