Gilead Sciences (Nasdaq: GILD) and Merck (NYSE: MRK) reported detailed Phase 3 ISLEND-1 and ISLEND-2 Week 48 results for the investigational once-weekly oral HIV regimen islatravir 2 mg/lenacapavir 300 mg (ISL/LEN) in virologically suppressed adults who switched from daily antiretroviral therapy.
According to Gilead and Merck, ISL/LEN was noninferior to BIKTARVY in ISLEND-1, with 0% vs 0.3% of participants having HIV-1 RNA ≥50 copies/mL, and noninferior to standard of care in ISLEND-2, with 0.3% vs 1.3% above this threshold. Overall safety, serious adverse events and discontinuations were generally low and similar to comparators, though ISLEND-2 showed a higher rate of treatment-related adverse events with ISL/LEN. CD4+ T-cell counts, lymphocyte counts and body weight remained stable, and ISLEND-2 participants reported higher treatment satisfaction and lower treatment burden. These data will support planned regulatory submissions; ISL/LEN remains investigational and not approved.
Gilead Sciences (Nasdaq: GILD) will present extensive new HIV research at the 26th International AIDS Conference (AIDS 2026) in Rio de Janeiro from July 26-31. Key data include 52-week open-label extension results from the Phase 3 PURPOSE 1 and PURPOSE 2 PrEP trials of twice-yearly lenacapavir, showing continued high efficacy, very high adherence (96% and 92%) and a consistent safety profile with no new signals. PURPOSE 1 recorded zero HIV infections during the extension, while PURPOSE 2 reported one infection among participants continuing lenacapavir. Gilead and Merck (NYSE: MRK) will also present full Phase 3 ISLEND-1 and ISLEND-2 results on a once-weekly investigational islatravir/lenacapavir oral regimen, alongside multiple Biktarvy and long-acting pipeline studies. Gilead highlights progress on its global access strategy for twice-yearly lenacapavir PrEP, expanding its no-profit supply program target from 2 million to up to 3 million people through 2028 and reporting availability in 10 priority sub-Saharan African countries.
Gilead (Nasdaq:GILD) received U.S. FDA approval for Trodelvy as first-line treatment for unresectable locally advanced or metastatic triple-negative breast cancer (mTNBC). Trodelvy can be used alone in PD-(L)1–ineligible patients or with Keytruda/Keytruda Qlex in PD-L1 CPS ≥10 tumors.
Approval is based on Phase 3 ASCENT-03 and ASCENT-04 data, where Trodelvy-based regimens reduced risk of progression or death by 38% and 35% versus chemotherapy-based comparators and extended median duration of response to 12.2 vs 7.2 months and 16.5 vs 9.2 months.
Gilead (Nasdaq:GILD) received European Commission approval for Trodelvy as first-line monotherapy for adults with unresectable or metastatic triple-negative breast cancer who have not had prior systemic metastatic therapy and are not candidates for PD-1/PD-L1 inhibitors.
The decision, covering the EU plus Norway, Iceland and Liechtenstein, is based on Phase 3 ASCENT-03, where Trodelvy cut the risk of progression or death by 38% versus chemotherapy. Trodelvy is the first antibody-drug conjugate and first new first-line treatment option in 20 years in Europe for this patient group and carries a boxed warning for severe neutropenia and diarrhea.
Gilead (Nasdaq:GILD) announced that the U.S. FDA has accepted its sNDA for once-weekly oral Yeztugo (lenacapavir) 300‑mg as investigational PrEP for HIV prevention. The FDA set a PDUFA date of February 2, 2027. The filing is supported by PURPOSE 1 and PURPOSE 2 trial results showing high efficacy in diverse populations. If approved, it could become the first long-acting oral PrEP option. Yeztugo’s current injectable PrEP indication and boxed warning emphasize strict HIV testing to reduce resistance risk.
Gilead (NASDAQ:GILD) announced a donation of more than 2,000 vials of intravenous remdesivir to Uganda to support the current Ebola Bundibugyo virus disease (BVD) outbreak. The medicine is supplied under compassionate use and MEURI frameworks, with additional supply being prepared.
Gilead is also preparing to support requests from the Democratic Republic of the Congo, WHO and other partners for remdesivir and obeldesivir as part of regional Ebola BVD response and planned clinical trials.

Gilead and Merck (NYSE:MRK) reported positive topline Phase 3 results for once-weekly oral HIV regimen islatravir/lenacapavir (ISL/LEN). Both ISLEND-1 and ISLEND-2 met the Week 48 primary endpoint, showing statistical non-inferiority to daily BIKTARVY or standard of care, with generally comparable safety. The partners plan global regulatory filings.
Merck (NYSE: MRK) and Gilead announced discontinuation of the Phase 3 KEYNOTE-D46/EVOKE-03 study of Trodelvy plus KEYTRUDA versus KEYTRUDA alone in previously untreated metastatic NSCLC patients with PD-L1 TPS ≥50%.
The eDMC recommended stopping after PFS failed to reach statistical significance and OS is unlikely to do so; safety was consistent with known profiles and no new safety signals emerged.
