FOSTER CITY, Calif.--(BUSINESS WIRE)--Gilead Sciences, Inc. (Nasdaq: GILD) today announced positive topline results from the Phase 3 ASCENT-03 study of Trodelvy® (sacituzumab govitecan-hziy). The study met its primary endpoint, demonstrating a highly statistically significant and clinically meaningful improvement in progression-free survival (PFS) compared to chemotherapy in patients with first-line metastatic triple-negative breast cancer (mTNBC) who are not candidates for PD-1/PD-L1 inhibitors, meaning they are PD-L1 negative or are ineligible to receive immunotherapy. “Almost half of the patients diagnosed with metastatic triple-negative breast cancer do not receive treatment beyond first-line, demonstrating an urgent need for innovative treatment options in this early setting,” said Dr. Javier Cortes, Head of the International Breast Cancer Center in Spain and principal investigator of the ASCENT-03 study. “Traditional chemotherapy has been the standard of care for early treatment of metastatic triple-negative breast cancer, and we know that therapeutic advances in this disease area serve a critical unmet need for patients and the broader oncology community.” Together with the recently announced positive results from the ASCENT-04 study evaluating Trodelvy plus Keytruda® in patients with previously untreated PD-L1+ metastatic TNBC, Trodelvy now has the potential to be the backbone treatment for all patients across first-line mTNBC. Detailed data from the ASCENT-04 study will be shared during the American Society of Clinical Oncology (ASCO) meeting taking place May 30 – June 3, 2025. “The ASCENT-03 outcome represents the first clinically meaningful advance for this patient population in over 20 years versus chemotherapy,” said Dietmar Berger, MD, PhD, Chief Medical Officer, Gilead Sciences. “By addressing this aggressive and difficult to treat disease earlier, we can potentially improve treatment options for the high unmet need that patients with metastatic triple-negative breast cancer face.” The safety profile of Trodelvy in the ASCENT-03 study was consistent with prior studies, and no new safety signals were identified in this patient population. Overall survival (OS) is a key secondary endpoint and was not mature at the time of PFS primary analysis. No OS detriment was observed. Gilead will continue to monitor OS outcomes, with ongoing patient follow-up and further analysis planned. Detailed results from the ASCENT-03 study will be presented at a future medical meeting and discussed with regulatory authorities. The use of Trodelvy in first-line mTNBC is investigational, and the safety and efficacy of this use have not been established. Healthcare professionals have well-established experience with Trodelvy, which has shown generally consistent outcomes across both clinical trials and real-world studies in 60,000+ patients across 50+ countries over approximately five years. It is the only antibody-drug conjugate (ADC) with four positive Phase 3 trials in HER2- (IHC 0, IHC 1+ or IHC 2+/ISH–) metastatic breast cancer (mBC), and remains the only approved Trop-2-directed ADC that has demonstrated meaningful survival advantages in two different types of metastatic breast cancers: 2L mTNBC and pre-treated HR+/HER2- mBC. Trodelvy is a Category 1 preferred treatment for both currently approved indications per the National Comprehensive Cancer Network® (NCCN®) Clinical Practice Guidelines in Oncology (NCCN Guidelinesi) and the only ADC with an ESMO Magnitude of Clinical Benefit Scale (MCBS) rating of 5 for mTNBC. Trodelvy also has an MCBS rating of 4 for women with HR+/HER2- mBC. Currently, Gilead has additional ongoing Phase 3 studies investigating Trodelvy across HER2- (IHC 0, IHC 1+ or IHC 2+/ISH–) breast cancer including the ASCENT-07 pivotal trial in patients with HR+/HER2- mBC who have received endocrine therapy, and the ASCENT-05 pivotal trial in patients with early-stage TNBC (eTNBC). Trodelvy is also being evaluated in additional Phase 3 studies across a range of tumor types, including in lung and gynecologic cancers. Gilead would like to thank the patients, families, investigators and advocates who have contributed and continue to contribute to this important research. We remain committed to advancing care to address the unmet needs for the breast cancer community.

About Triple-Negative Breast Cancer (In Patients Who Are Not Candidates for PD-1/PD-L1 inhibitors) Triple-negative breast cancer (TNBC) is the most aggressive type of breast cancer and has historically been difficult to treat, accounting for approximately 15% of all breast cancers. TNBC disproportionately impacts younger, pre-menopausal as well as Black and Hispanic women. TNBC cells do not have estrogen and progesterone receptors and have limited HER2. Due to the nature of TNBC, treatment options are extremely limited compared with other breast cancer types. TNBC has a higher chance of recurrence and metastases than other breast cancer types. The average time to metastatic recurrence for TNBC is approximately 2.6 years compared with 5 years for other breast cancers, and the relative five-year survival rate is much lower. Among women with metastatic TNBC, the five-year survival rate is 12%, compared with 28% for those with other types of mBC. Chemotherapy remains the mainstay of treatment in first-line mTNBC patients who are not candidates for PD-1/PD-L1 inhibitors, and the need to improve outcomes continues to be high. In mTNBC overall, ~50% of patients do not receive treatment beyond 1L setting, demonstrating a need for additional effective earlier-line treatment options. About the ASCENT-03 Study The ASCENT-03 study is a global, open-label, randomized Phase 3 trial evaluating the efficacy and safety of sacituzumab govitecan compared with treatment of physician’s choice in patients with previously untreated, locally advanced, inoperable, or metastatic triple-negative breast cancer (mTNBC) whose tumors do not express PD-L1, or who are PD-L1 positive and previously treated with a PD-(L)1 inhibitor in the curative setting. ~540 patients were enrolled across multiple study sites worldwide. Patients were randomized 1:1 to receive either sacituzumab govitecan (10 mg/kg intravenously on Days 1 and 8 of a 21-day cycle) or treatment of physician’s choice, which included gemcitabine plus carboplatin, paclitaxel, or nab-paclitaxel. Treatment continued until blinded independent central review (BICR)-verified disease progression or unacceptable toxicity. Patients randomized to chemotherapy were eligible to crossover to sacituzumab govitecan upon disease progression. The primary endpoint of the study is progression-free survival (PFS) as assessed by BICR according to RECIST v1.1. Secondary endpoints include overall survival (OS), objective response rate (ORR), duration of response (DOR), time to onset of response (TTR), patient-reported outcomes (PROs), and safety. More information about ASCENT-03 is available at ClinicalTrials.gov: NCT05382299. About Trodelvy Trodelvy® (sacituzumab govitecan-hziy) is a first-in-class Trop-2-directed antibody-drug conjugate. Trop-2 is a cell surface antigen highly expressed in multiple tumor types, including in more than 90% of breast and lung cancers. Trodelvy is intentionally designed with a proprietary hydrolyzable linker attached to SN-38, a topoisomerase I inhibitor payload. This unique combination delivers potent activity to both Trop-2 expressing cells and the tumor microenvironment through a bystander effect. Trodelvy is currently approved in more than 50 countries for second-line or later metastatic triple-negative breast cancer (TNBC) patients and in more than 40 countries for certain patients with pre-treated HR+/HER2- metastatic breast cancer. Trodelvy is currently being evaluated in multiple ongoing Phase 3 trials across a range of tumor types with high Trop-2 expression. These studies with Trodelvy, both in monotherapy and in combination with pembrolizumab, involve earlier lines of treatment for TNBC and HR+/HER2- breast cancer—including in curative settings—as well as in lung and gynecologic cancers, where previous proof-of-concept studies have demonstrated clinical activity. INDICATIONS TRODELVY® (sacituzumab govitecan-hziy) is a Trop-2-directed antibody and topoisomerase inhibitor conjugate indicated for the treatment of adult patients with: Unresectable locally advanced or metastatic triple-negative breast cancer (mTNBC) who have received two or more prior systemic therapies, at least one of them for metastatic disease. Unresectable locally advanced or metastatic hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2)-negative (IHC 0, IHC 1+ or IHC 2+/ISH–) breast cancer who have received endocrine-based therapy and at least two additional systemic therapies in the metastatic setting. IMPORTANT SAFETY INFORMATION BOXED WARNING: NEUTROPENIA AND DIARRHEA CONTRAINDICATIONS Severe hypersensitivity reaction to TRODELVY. WARNINGS AND PRECAUTIONS Neutropenia: Severe, life-threatening, or fatal neutropenia can occur as early as the first cycle of treatment and may require dose modification. Neutropenia occurred in 64% of patients treated with TRODELVY. Grade 3-4 neutropenia occurred in 49% of patients. Febrile neutropenia occurred in 6%. Neutropenic colitis occurred in 1.4%. Primary prophylaxis with G-CSF is recommended starting in the first cycle of treatment in all patients at increased risk of febrile neutropenia, including older patients, patients with previous neutropenia, poor performance status, organ dysfunction, or multiple comorbidities. Monitor absolute neutrophil count (ANC) during treatment. Withhold TRODELVY for ANC below 1500/mm3 on Day 1 of any cycle or below 1000/mm3 on Day 8 of any cycle. Withhold TRODELVY for neutropenic fever. Treat neutropenia with G-CSF and administer prophylaxis in subsequent cycles as clinically indicated or indicated in Table 2 of USPI. Diarrhea: Diarrhea occurred in 64% of all patients treated with TRODELVY. Grade 3-4 diarrhea occurred in 11% of patients. One patient had intestinal perforation following diarrhea. Diarrhea that led to dehydration and subsequent acute kidney injury occurred in 0.7% of all patients. Withhold TRODELVY for Grade 3-4 diarrhea and resume when resolved to ≤ Grade 1. At onset, evaluate for infectious causes and if negative, promptly initiate loperamide, 4 mg initially followed by 2 mg with every episode of diarrhea for a maximum of 16 mg daily. Discontinue loperamide 12 hours after diarrhea resolves. Additional supportive measures (e.g., fluid and electrolyte substitution) may also be employed as clinically indicated. Patients who exhibit an excessive cholinergic response to treatment can receive appropriate premedication (e.g., atropine) for subsequent treatments. Hypersensitivity and Infusion-Related Reactions: TRODELVY can cause serious hypersensitivity reactions including life-threatening anaphylactic reactions. Severe signs and symptoms included cardiac arrest, hypotension, wheezing, angioedema, swelling, pneumonitis, and skin reactions. Hypersensitivity reactions within 24 hours of dosing occurred in 35% of patients. Grade 3-4 hypersensitivity occurred in 2% of patients. The incidence of hypersensitivity reactions leading to permanent discontinuation of TRODELVY was 0.2%. The incidence of anaphylactic reactions was 0.2%. Pre-infusion medication is recommended. Have medications and emergency equipment to treat such reactions available for immediate use. Observe patients closely for hypersensitivity and infusion-related reactions during each infusion and for at least 30 minutes after completion of each infusion. Permanently discontinue TRODELVY for Grade 4 infusion-related reactions. Nausea and Vomiting: TRODELVY is emetogenic and can cause severe nausea and vomiting. Nausea occurred in 64% of all patients treated with TRODELVY and Grade 3-4 nausea occurred in 3% of these patients. Vomiting occurred in 35% of patients and Grade 3-4 vomiting occurred in 2% of these patients. Premedicate with a two or three drug combination regimen (e.g., dexamethasone with either a 5-HT3 receptor antagonist or an NK1 receptor antagonist as well as other drugs as indicated) for prevention of chemotherapy-induced nausea and vomiting (CINV). Withhold TRODELVY doses for Grade 3 nausea or Grade 3-4 vomiting and resume with additional supportive measures when resolved to Grade ≤ 1. Additional antiemetics and other supportive measures may also be employed as clinically indicated. All patients should be given take-home medications with clear instructions for prevention and treatment of nausea and vomiting. Increased Risk of Adverse Reactions in Patients with Reduced UGT1A1 Activity: Patients homozygous for the uridine diphosphate-glucuronosyl transferase 1A1 (UGT1A1)*28 allele are at increased risk for neutropenia, febrile neutropenia, and anemia and may be at increased risk for other adverse reactions with TRODELVY. The incidence of Grade 3-4 neutropenia was 58% in patients homozygous for the UGT1A1*28, 49% in patients heterozygous for the UGT1A1*28 allele, and 43% in patients homozygous for the wild-type allele. The incidence of Grade 3-4 anemia was 21% in patients homozygous for the UGT1A1*28 allele, 10% in patients heterozygous for the UGT1A1*28 allele, and 9% in patients homozygous for the wild-type allele. Closely monitor patients with known reduced UGT1A1 activity for adverse reactions. Withhold or permanently discontinue TRODELVY based on clinical assessment of the onset, duration and severity of the observed adverse reactions in patients with evidence of acute early-onset or unusually severe adverse reactions, which may indicate reduced UGT1A1 function. Embryo-Fetal Toxicity: Based on its mechanism of action, TRODELVY can cause teratogenicity and/or embryo-fetal lethality when administered to a pregnant woman. TRODELVY contains a genotoxic component, SN-38, and targets rapidly dividing cells. Advise pregnant women and females of reproductive potential of the potential risk to a fetus. Advise females of reproductive potential to use effective contraception during treatment with TRODELVY and for 6 months after the last dose. Advise male patients with female partners of reproductive potential to use effective contraception during treatment with TRODELVY and for 3 months after the last dose. ADVERSE REACTIONS In the pooled safety population, the most common (≥ 25%) adverse reactions including laboratory abnormalities were decreased leukocyte count (84%), decreased neutrophil count (75%), decreased hemoglobin (69%), diarrhea (64%), nausea (64%), decreased lymphocyte count (63%), fatigue (51%), alopecia (45%), constipation (37%), increased glucose (37%), decreased albumin (35%), vomiting (35%), decreased appetite (30%), decreased creatinine clearance (28%), increased alkaline phosphatase (28%), decreased magnesium (27%), decreased potassium (26%), and decreased sodium (26%). In the ASCENT study (locally advanced or metastatic triple-negative breast cancer), the most common adverse reactions (incidence ≥25%) were fatigue, diarrhea, nausea, alopecia, constipation, vomiting, abdominal pain, and decreased appetite. The most frequent serious adverse reactions (SAR) (>1%) were neutropenia (7%), diarrhea (4%), and pneumonia (3%). SAR were reported in 27% of patients, and 5% discontinued therapy due to adverse reactions. The most common Grade 3-4 lab abnormalities (incidence ≥25%) in the ASCENT study were reduced neutrophils, leukocytes, and lymphocytes. In the TROPiCS-02 study (locally advanced or metastatic HR-positive, HER2-negative breast cancer), the most common adverse reactions (incidence ≥25%) were diarrhea, fatigue, nausea, alopecia, and constipation. The most frequent serious adverse reactions (SAR) (>1%) were diarrhea (5%), febrile neutropenia (4%), neutropenia (3%), abdominal pain, colitis, neutropenic colitis, pneumonia, and vomiting (each 2%). SAR were reported in 28% of patients, and 6% discontinued therapy due to adverse reactions. The most common Grade 3-4 lab abnormalities (incidence ≥25%) in the TROPiCS-02 study were reduced neutrophils and leukocytes. DRUG INTERACTIONS UGT1A1 Inhibitors: Concomitant administration of TRODELVY with inhibitors of UGT1A1 may increase the incidence of adverse reactions due to potential increase in systemic exposure to SN-38. Avoid administering UGT1A1 inhibitors with TRODELVY. UGT1A1 Inducers: Exposure to SN-38 may be reduced in patients concomitantly receiving UGT1A1 enzyme inducers. Avoid administering UGT1A1 inducers with TRODELVY. Please see full Prescribing Information, including BOXED WARNING.
