Data from the Arm D of SEQUOIA demonstrate that treatment with BRUKINSA plus venetoclax has the potential to drive progression-free survival and overall deep and durable responses across the frontline CLL patient spectrum, including patients with high-risk mutational status. The best undetectable minimal residual disease (uMRD) rate in peripheral blood at a sensitivity level 10-4 was 59%. These efficacy responses observed in Arm D, despite the high proportion of high-risk patients enrolled, are in line with recent fixed-duration studies in fitter, healthier patient populations. Additionally, 11 patients in Arm D were able to discontinue treatment early due to meeting uMRD-guided stopping criteria, and 9 patients remain in ongoing clinical remission with sustained uMRD (1 patient discontinued study while in clinical remission), allowing them to remain treatment-free. In patients without del(17p) and TP53 mutations, 43% achieved uMRD by cycle 16 and 60% by cycle 28. These data were published today in the Journal of Clinical Oncology.

"While many first-line CLL studies have excluded patient populations with high-risk disease features, BeOne included those patients in SEQUOIA," said Lai Wang, Ph.D., Global Head of R&D at BeOne. "Nearly 88% of patients with del(17p) and /or TP53 treated with BRUKINSA plus venetoclax remain progression-free at 36 months, which represents an unprecedented outcome for a doublet regimen in this difficult-to-treat patient population. These new SEQUOIA data reinforce BRUKINSA’s versatility across the spectrum of CLL patients and reflect BeOne’s commitment to progressing a pipeline built to meet unmet patient needs and elevate the standard of care."

Arm D Highlights (Abstract 7009)
SEQUOIA Arm D investigated BRUKINSA plus venetoclax in 114 patients with treatment-naïve (TN) CLL / small lymphocytic lymphoma (SLL) with or without del(17p) and/or TP53 high-risk mutations. At a median follow-up of 31.2 months, the combination induced a high 24-month progression-free survival (PFS) rate of 92% (95% CI, 85-96%) and an impressive overall response rate (ORR) of 97%. The 24-month overall survival (OS) rate was 96% (95% CI, 90%-98%). Of those patients with del(17p) and/or TP53 mutations, 94% were progression-free at 24 months and 87.6% were progression-free at 36 months.

The safety profile of BRUKINSA was consistent with the results of prior studies with no new safety signals identified.

"The zanubrutinib and venetoclax combination achieved deep, durable responses across risk groups, including patients with TP53 mutations, with a generally manageable safety profile. Notably, several patients were able to discontinue treatment and maintain remission, highlighting the potential for time-limited therapy with meaningful disease control," said Mazyar Shadman, M.D., M.P.H., Associate Professor and Innovators Network Endowed Chair, Medical Director, Cellular Immunotherapy and the Bezos Family Immunotherapy Clinic at Fred Hutch Cancer Center. "Generating data to inform future CLL treatment strategies that allow for both continuous therapy and planned time off treatment is essential, particularly for high-risk patients who are the most likely to succumb to this disease."

Arm C Highlights (Abstract 7011)
Arm C of the SEQUOIA study investigated BRUKINSA monotherapy in patients with TN CLL / SLL and del(17p) mutations and is the largest prospective cohort of CLL/SLL patients with del(17p). At a median follow-up of over 5.5 years (65.8 months), most patients remained progression-free. Notably, at 60 months, 72.2% of patients who received BRUKINSA remained progression-free (95% CI, 62.4, 79.8). When adjusted for the impact of the COVID-19 pandemic, 73.0% of patients in the cohort remained progression-free (95% CI, 63.3, 80.6) at 60 months. The 60-month OS rate was 85.1% (95% CI, 76.9, 90.6) and 87.0% (95% CI, 79.0, 92.1) when adjusted for COVID-19. At the time of data cut-off, the ORR was 97.3%, and 62.2% of patients were still receiving treatment with BRUKINSA.

The safety profile of BRUKINSA was consistent with the results of prior studies with no new safety signals identified.

About Chronic Lymphocytic Leukemia
Chronic lymphocytic leukemia (CLL) is a life-threatening cancer of adults. It is a type of mature B-cell malignancy in which abnormal leukemic B lymphocytes (a type of white blood cells) arise from the bone marrow and flood peripheral blood, bone marrow, and lymphoid tissues.1,2 CLL is the most common type of leukemia in adults, accounting for about one-third of new cases.2,3 Approximately 20,700 new cases of CLL will be diagnosed in the U.S. in 2024.3

About 50% of CLL patients have high-risk genetic features – including del(17p), TP53 or unmutated IGHV – that may limit the effectiveness of some treatments (e.g. chemotherapy) and increase the likelihood of disease progression.4,5

About SEQUOIA
SEQUOIA (NCT03336333) is a randomized, multicenter, global Phase 3 trial designed to evaluate the efficacy and safety of BRUKINSA in patients with treatment-naïve (TN) chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL). The trial consists of three cohorts:

Cohort 1 (n=479): randomized 1:1 to receive BRUKINSA (n=241) or bendamustine plus rituximab (n=238) until disease progression or unacceptable toxicity, in patients not harboring del(17p); data from this group comprise the primary endpoint;
Cohort 2/Arm C (n=110): patients with del(17p) receiving BRUKINSA as a monotherapy; and
Cohort 3/Arm D (n=114): 66 patients with del(17p) and/or pathogenic TP53 mutation and 47 patients without del(17p) or TP53 were enrolled, with 110 patients receiving BRUKINSA in combination with venetoclax.
The results of Cohort 1 of the SEQUOIA study led to the regulatory approval of BRUKINSA monotherapy in the treatment of TN CLL in many countries across the world, including approvals by the U.S. Food and Drug Administration and the European Medicines Agency. The primary endpoint of the trial is progression-free survival (PFS), as assessed by an independent review committee (IRC). Secondary endpoints include investigator-assessed PFS, IRC- and investigator-assessed overall response rate (ORR), overall survival (OS), and safety, as well as PFS and ORR in patients with del(17p).

About BRUKINSA (zanubrutinib)
BRUKINSA is an orally available, small molecule inhibitor of Bruton’s tyrosine kinase (BTK) designed to deliver complete and sustained inhibition of the BTK protein by optimizing bioavailability, half-life, and selectivity. With differentiated pharmacokinetics compared with other approved BTK inhibitors, BRUKINSA has been demonstrated to inhibit the proliferation of malignant B cells within a number of disease-relevant tissues.

BRUKINSA has the broadest label globally of any BTK inhibitor and is the only BTK inhibitor to provide the flexibility of once or twice daily dosing. Additionally, BRUKINSA is also the only BTK inhibitor to demonstrate superiority to another BTK inhibitor in a Phase 3 study.

The global BRUKINSA clinical development program includes about 7,100 patients enrolled in 30 countries and regions across more than 35 trials. BRUKINSA is approved in more than 75 markets, and more than 200,000 patients have been treated globally.

U.S. Indications and Important Safety Information for BRUKINSA (zanubrutinib)

INDICATIONS

BRUKINSA is a kinase inhibitor indicated for the treatment of adult patients with:

Chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL).
Waldenström’s macroglobulinemia (WM).
Mantle cell lymphoma (MCL) who have received at least one prior therapy.
Relapsed or refractory marginal zone lymphoma (MZL) who have received at least one anti-CD20-based regimen.
Relapsed or refractory follicular lymphoma (FL), in combination with obinutuzumab, after two or more lines of systemic therapy.

IMPORTANT SAFETY INFORMATION

Warnings and Precautions

Hemorrhage

Fatal and serious hemorrhage has occurred in patients with hematological malignancies treated with BRUKINSA. Grade 3 or higher hemorrhage including intracranial and gastrointestinal hemorrhage, hematuria, and hemothorax was reported in 3.8% of patients treated with BRUKINSA in clinical trials, with fatalities occurring in 0.2% of patients. Bleeding of any grade, excluding purpura and petechiae, occurred in 32% of patients.

Bleeding has occurred in patients with and without concomitant antiplatelet or anticoagulation therapy. Coadministration of BRUKINSA with antiplatelet or anticoagulant medications may further increase the risk of hemorrhage.

Monitor for signs and symptoms of bleeding. Discontinue BRUKINSA if intracranial hemorrhage of any grade occurs. Consider the benefit-risk of withholding BRUKINSA for 3-7 days before and after surgery depending upon the type of surgery and the risk of bleeding.

Infections

Fatal and serious infections (including bacterial, viral, or fungal infections) and opportunistic infections have occurred in patients with hematological malignancies treated with BRUKINSA. Grade 3 or higher infections occurred in 26% of patients, most commonly pneumonia (7.9%), with fatal infections occurring in 3.2% of patients. Infections due to hepatitis B virus (HBV) reactivation have occurred.

Consider prophylaxis for herpes simplex virus, pneumocystis jirovecii pneumonia, and other infections according to standard of care in patients who are at increased risk for infections. Monitor and evaluate patients for fever or other signs and symptoms of infection and treat appropriately.

Cytopenias

Grade 3 or 4 cytopenias, including neutropenia (21%), thrombocytopenia (8%) and anemia (8%) based on laboratory measurements, developed in patients treated with BRUKINSA. Grade 4 neutropenia occurred in 10% of patients, and Grade 4 thrombocytopenia occurred in 2.5% of patients.

Monitor complete blood counts regularly during treatment and interrupt treatment, reduce the dose, or discontinue treatment as warranted. Treat using growth factor or transfusions, as needed.

Second Primary Malignancies

Second primary malignancies, including non-skin carcinoma, have occurred in 14% of patients treated with BRUKINSA. The most frequent second primary malignancy was non-melanoma skin cancers (8%), followed by other solid tumors in 7% of the patients (including melanoma in 1% of patients) and hematologic malignancies (0.7%). Advise patients to use sun protection and monitor patients for the development of second primary malignancies.

Cardiac Arrhythmias

Serious cardiac arrhythmias have occurred in patients treated with BRUKINSA. Atrial fibrillation and atrial flutter were reported in 4.4% patients treated with BRUKINSA, including Grade 3 or higher cases in 1.9% of patients. Patients with cardiac risk factors, hypertension, and acute infections may be at increased risk. Grade 3 or higher ventricular arrhythmias were reported in 0.3% of patients.

Monitor for signs and symptoms of cardiac arrhythmias (e.g., palpitations, dizziness, syncope, dyspnea, chest discomfort), manage appropriately, and consider the risks and benefits of continued BRUKINSA treatment.

Hepatotoxicity, Including Drug-Induced Liver Injury

Hepatotoxicity, including severe, life-threatening, and potentially fatal cases of drug-induced liver injury (DILI), has occurred in patients treated with Bruton tyrosine kinase inhibitors, including BRUKINSA.

Evaluate bilirubin and transaminases at baseline and throughout treatment with BRUKINSA. For patients who develop abnormal liver tests after BRUKINSA, monitor more frequently for liver test abnormalities and clinical signs and symptoms of hepatic toxicity. If DILI is suspected, withhold BRUKINSA. Upon confirmation of DILI, discontinue BRUKINSA.

Embryo-Fetal Toxicity

Based on findings in animals, BRUKINSA can cause fetal harm when administered to a pregnant woman. Administration of zanubrutinib to pregnant rats during the period of organogenesis caused embryo-fetal toxicity, including malformations at exposures that were 5 times higher than those reported in patients at the recommended dose of 160 mg twice daily. Advise women to avoid becoming pregnant while taking BRUKINSA and for 1 week after the last dose. Advise men to avoid fathering a child during treatment and for 1 week after the last dose. If this drug is used during pregnancy, or if the patient becomes pregnant while taking this drug, the patient should be apprised of the potential hazard to a fetus.

Adverse Reactions

The most common adverse reactions (≥30%), including laboratory abnormalities, in patients who received BRUKINSA (N=1729) are decreased neutrophil count (51%), decreased platelet count (41%), upper respiratory tract infection (38%), hemorrhage (32%), and musculoskeletal pain (31%).

Drug Interactions

CYP3A Inhibitors: When BRUKINSA is co-administered with a strong CYP3A inhibitor, reduce BRUKINSA dose to 80 mg once daily. For coadministration with a moderate CYP3A inhibitor, reduce BRUKINSA dose to 80 mg twice daily.

CYP3A Inducers: Avoid coadministration with strong or moderate CYP3A inducers. Dose adjustment may be recommended with moderate CYP3A inducers.

Specific Populations

Hepatic Impairment: The recommended dose of BRUKINSA for patients with severe hepatic impairment is 80 mg orally twice daily.

Trodelvy® Plus Keytruda® Reduces Risk of Disease Progression or Death by 35% Versus Keytruda and Chemotherapy in First-Line PD-L1+ Metastatic Triple-Negative Breast Cancer

On June 1, 2025 Gilead Sciences, Inc. (Nasdaq: GILD) reported Trodelvy (sacituzumab govitecan-hziy) plus Keytruda (pembrolizumab) reduced the risk of disease progression or death by 35% (HR: 0.65) versus standard of care Keytruda plus chemotherapy in first-line treatment for patients with PD-L1+ (CPS ≥10) metastatic triple-negative breast cancer (TNBC) (Press release, Gilead Sciences, JUN 1, 2025, View Source [SID1234653552]). Trodelvy when given in combination with Keytruda resulted in a median progression-free survival (PFS) of 11.2 months vs 7.8 months when Keytruda was given in combination with chemotherapy. These data from the pivotal Phase 3 ASCENT-04/KEYNOTE-D19 study will be presented today as a late-breaking oral presentation at the 2025 ASCO (Free ASCO Whitepaper) Annual Congress (Abstract #LBA109).

"These results are an important advancement for patients with PD-L1–positive metastatic triple-negative breast cancer, a population for whom first-line options remain limited," said Sara Tolaney, MD, MPH, Dana-Farber Cancer Institute and primary investigator of the ASCENT-04 study. "By combining sacituzumab govitecan with pembrolizumab, we’re seeing meaningful gains in progression-free survival and a promising trend in overall survival—findings that could support a new frontline standard of care for this aggressive disease."

"The ASCENT-04 results build on Gilead’s aspiration of transforming the treatment of breast cancer with Trodelvy in earlier lines of therapy," said Dietmar Berger, MD, PhD. "Together with the recently reported clinically meaningful topline results from our first-line monotherapy study, these data reinforce our confidence in Trodelvy’s utility both as a single agent and in combination with immunotherapy in the frontline metastatic TNBC setting. We are actively engaging with the FDA to explore a potential regulatory path forward for this combination for the benefit of patients."

For the primary endpoint, the median PFS was 11.2 months (95% CI: 9.3-16.7) with Trodelvy plus Keytruda compared to 7.8 months (95% CI: 7.3-9.3) with Keytruda plus chemotherapy, with a median follow-up of 14 months. A highly statistically significant and clinically meaningful improvement was observed with Trodelvy plus Keytruda (n=221), showing a 35% reduction in the risk of disease progression or death (HR: 0.65; p<0.001) in the intent to treat population compared to standard of care Keytruda plus chemotherapy combination (n=222). The PFS benefit was generally consistent across key prespecified subgroups.

A numerically higher overall response rate was observed for the Trodelvy plus Keytruda combination [60% (95% CI: 52.9-66.3) versus 53% (95% CI: 46.4-59.9)], including 13% and 8% with a complete response, respectively, in the Trodelvy plus Keytruda and Keytruda plus chemotherapy arms. Notably, a substantially longer duration of response was observed with Trodelvy plus Keytruda [16.5 months (95% CI: 12.7-19.5) versus 9.2 months (95% CI: 7.6-11.3)]. Encouraging trends in overall survival (OS) were also observed, but data are immature at the time of PFS primary analysis. Overall survival follow-up remains ongoing and will continue to be monitored as a key secondary endpoint.

The safety profile of Trodelvy plus Keytruda in the ASCENT-04 study was consistent with the known safety profile of each agent. No new safety signals were identified with the combination and the combination did not exacerbate the safety profile of either therapy. The most frequent (≥10% of patients) grade ≥3 treatment-emergent adverse events with Trodelvy plus Keytruda were neutropenia (43%) and diarrhea (10%), and with Keytruda plus chemotherapy were neutropenia (45%), anemia (16%) and thrombocytopenia (14%). Fewer patients discontinued treatment due to adverse events on the Trodelvy plus Keytruda arm than with Keytruda plus chemotherapy (12% vs. 31%).

In addition to ASCENT-04, Gilead on May 23 announced topline results from ASCENT-03 demonstrating a highly statistically significant and clinically meaningful improvement in PFS compared to chemotherapy in patients with first-line metastatic TNBC who are not candidates for PD-1/PD-L1 inhibitors. Detailed results from the ASCENT-03 study will be presented at a future medical meeting and discussed with regulatory authorities.

The use of Trodelvy plus Keytruda in patients with first-line PD-L1+ metastatic TNBC and Trodelvy as monotherapy in patients with first-line metastatic TNBC who are not candidates for PD-1/PD-L1 inhibitors are investigational, and the safety and efficacy of these uses have not been established.

About Triple-Negative Breast Cancer with PD-L1+ Tumors

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 is diagnosed more frequently in younger and premenopausal women and is more prevalent in 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 mTNBC, the five-year survival rate is 12%, compared with 28% for those with other types of mBC.

Despite progress in treatment, first-line mTNBC has seen limited new approvals in recent years for tumors that express PD-L1+, and additional options are urgently needed. Despite recent advances, over 50% of patients do not receive treatment beyond first-line, reinforcing the urgent need for new options to help improve patient outcomes. Breast cancers expressing PD-L1 are overall more aggressive and associated with reduced survival time.

About the ASCENT-04/KEYNOTE-D19 Study

In 2021, Gilead entered a collaboration with Merck & Co. to investigate sacituzumab govitecan in combination with pembrolizumab in the Phase 3 trial, ASCENT-04/KEYNOTE-D19. The ASCENT-04/KEYNOTE-D19 study is a global, open-label, randomized Phase 3 trial evaluating the efficacy and safety of sacituzumab govitecan in combination with pembrolizumab compared with treatment of chemotherapy plus pembrolizumab in patients with previously untreated, inoperable locally advanced or metastatic triple-negative breast cancer (TNBC) whose tumors express PD-L1. The study enrolled 443 patients across multiple study sites.

Patients were randomized in a 1:1 ratio to receive either sacituzumab govitecan (10 mg/kg intravenously on Days 1 and 8 of a 21-day cycle) plus pembrolizumab (200 mg intravenously on Day 1 of a 21-day cycle) or chemotherapy plus pembrolizumab. The chemotherapy regimen 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 allowed to crossover and receive sacituzumab govitecan upon disease progression.

The primary endpoint of the study is progression-free survival (PFS) as determined by BICR using 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-04/KEYNOTE-D19 is available at ClinicalTrials.gov: NCT05382286.

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

TRODELVY can cause severe, life-threatening, or fatal neutropenia. Withhold TRODELVY for absolute neutrophil count below 1500/mm3 or neutropenic fever. Monitor blood cell counts periodically during treatment. Primary prophylaxis with G-CSF is recommended for all patients at increased risk of febrile neutropenia. Initiate anti-infective treatment in patients with febrile neutropenia without delay.
TRODELVY can cause severe diarrhea. Monitor patients with diarrhea and give fluid and electrolytes as needed. At the onset of diarrhea, evaluate for infectious causes and, if negative, promptly initiate loperamide. If severe diarrhea occurs, withhold TRODELVY until resolved to ≤ Grade 1 and reduce subsequent doses.
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.

"The new analyses we presented from the IGNYTE clinical trial of RP1 plus nivolumab in anti-PD-1 failed melanoma confirms our belief in the systemic activity of the combination, and also shows robust responses in injected liver and lung lesions with an acceptable safety profile," said Kostas Xynos, M.D., Chief Medical Officer of Replimune. "Additional data also presented at the meeting shows that RP1 can be handled safely with no additional biosafety protocols required confirming that standard disinfection procedures are sufficient for clean up."

Key findings are outlined below.

Poster Presentation: Response analysis for injected and non-injected lesions and the safety and efficacy of superficial and deep RP1 injection in the registrational cohort of anti-PD-1-failed melanoma patients of the IGNYTE trial (Track: Melanoma/Skin Cancers; June 1, 2025, 9:00 am – 12:00 pm CDT; Location: Hall A, Board 20; Abstract: 9537)

The poster included an analysis from the IGNYTE clinical trial of RP1 plus nivolumab in the cohort of anti-PD-1 failed melanoma patients (n=140). In the trial, the objective response rate (ORR) was 32.9% using RECIST 1.1. The complete response rate was 15.0% and landmark overall survival (OS) rates at 1, 2, and 3 years were 75.3%, 63.3%, and 54.8% respectively. Median OS has not been reached.
Patients experienced numerically higher objective response rates after receiving deep injections (± superficial) compared with superficial injections only. Deep responses were observed in injected and non-injected lesions.
The ORR by injection type using RECIST 1.1 was 29.8% when only superficial lesions were injected, 42.9% for deep/visceral plus superficial injections injected, and 40.9% when only deep/visceral lesions were injected.
There was a ≥30% reduction in 93.6% (73/78) of injected lesions and 79.0% (94/119) of non-injected lesions. The kinetics of response were similar in injected vs non-injected lesions.
Of the non-injected visceral organ lesions in responding patients, 96.2% (50/52) showed reduction from baseline, with 65.4% reduced by ≥30%.
RP1 injections directly into the lung and liver were generally well tolerated and resulted in few organ-specific adverse events that were easily managed.
Liver and lung injections had a tolerable safety profile.
No bleeding events were reported after liver injection.
Lung injections were associated with low rates of pneumothorax events, which were typically of low grade and manageable.
Overall, these data support the safety and efficacy of deep/visceral injections and demonstrate the development of a robust systemic anti-tumor response following treatment with RP1 plus nivolumab.
Poster Presentation: Biosafety analysis from the skin cancer cohorts in the IGNYTE clinical trial of RP1 (Track: Melanoma/Skin Cancers; June 1, 2025, 9:00 am – 12:00 pm CDT; Location: Hall A, Board 17; Abstract: 9534)

RP1 was assessed in various samples taken from patients.
This demonstrated that RP1 DNA is primarily detected at the injection site, consistent with RP1 replication in the tumor, and much more rarely on dressings, in blood, on mucous membranes or in urine.
In all cases, live RP1 was only rarely if ever detected, demonstrating that while residual RP1 DNA may be present, this does not indicate the presence of live RP1
There were no systemic herpetic infections in patients or reports of HSV-1 infections in contacts.
RP1 is completely neutralized using standard disinfectants within 30 seconds of contact, confirming that standard disinfection procedures are sufficient for RP1 clean-up.
Collectively these data demonstrate that the likelihood of transmission of RP1 to patients’ contacts or into the external environment is minimal, with no transmission having been reported to date.
Both posters will be available on the Company website under Events and Presentations.

About RP1
RP1 is Replimune’s lead product candidate and is based on a proprietary strain of herpes simplex virus engineered and genetically armed with a fusogenic protein (GALV-GP-R-) and GM-CSF intended to maximize tumor killing potency, the immunogenicity of tumor cell death and the activation of a systemic anti-tumor immune response.

About RP2
RP2 is based on a proprietary strain of herpes simplex virus engineered and genetically armed with a fusogenic protein (GALV-GP-R-) and GM-CSF intended to maximize tumor killing potency, the immunogenicity of tumor cell death and the activation of a systemic anti-tumor immune response. RP2 additionally expresses an anti-CTLA-4 antibody-like molecule, as well as GALV-GP-R- and GM-CSF. RP2 is intended to provide targeted and potent delivery of these proteins to the sites of immune response initiation in the tumor and draining lymph nodes, with the goal of focusing systemic-immune-based efficacy on tumors and limiting off-target toxicity.

"The FDA’s acceptance of our New Drug Application marks a significant milestone for Kura and Kyowa Kirin and, more importantly, for patients living with this genetic subset of AML, who face an aggressive form of the disease with few treatment options," said Troy Wilson, Ph.D., J.D., President and Chief Executive Officer of Kura Oncology. "This achievement reflects the strength of the clinical data for ziftomenib as well as the incredible commitment of our teams. Along with our partners at Kyowa Kirin, we look forward to continuing to work closely with the FDA throughout the review process and to prepare for the anticipated launch of this treatment, which holds potential to meaningfully impact the lives of patients and their families."

The NDA is based on results from the Phase 2 KOMET-001 registrational trial in R/R NPM1-mutant (NPM1-m) AML (NCT #04067336). The KOMET-001 trial achieved its primary endpoint of complete remission (CR) plus CR with partial hematological recovery (CRh) and the primary endpoint was statistically significant. Ziftomenib was well‑tolerated with limited myelosuppression and 3% ziftomenib-related discontinuations. The safety and tolerability of ziftomenib were consistent with previous reports, and the benefit-risk profile for ziftomenib is highly encouraging.

"Adult R/R NPM1-m AML patients face a significantly poor prognosis, highlighting the urgent need for innovative treatment options that can improve their outcomes," said Takeyoshi Yamashita, Ph.D., Executive Vice President and Chief Medical Officer of Kyowa Kirin. "The acceptance of this NDA is a crucial step in our ongoing efforts to explore and evaluate various therapeutic strategies for AML through our comprehensive clinical trials. Our dedicated teams at Kyowa Kirin and Kura are fully committed to working tirelessly to ensure that, once approved, ziftomenib is made available to AML patients as quickly as possible. We recognize the importance of this endeavor and are excited about the possibility of making a meaningful impact on the lives of those affected by this challenging disease."

The KOMET-001 registration-directed trial is designed to assess evidence of clinical activity, safety and tolerability of ziftomenib, the only investigational therapy to receive Breakthrough Therapy Designation (BTD) from the FDA for treatment of R/R NPM1-mutant AML. In addition to BTD, ziftomenib has received Fast Track and Orphan Drug Designations. The full data analyses from the KOMET-001 trial of ziftomenib in R/R NPM1-m AML patients have been selected for oral presentation on Monday, June 2nd at the 2025 American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting, and an encore presentation is planned at the 2025 European Hematology Association (EHA) (Free EHA Whitepaper) Congress.

About NPM1-Mutant AML

AML is the most common acute leukemia in adults and begins when the bone marrow makes abnormal myeloblasts (white blood cells), red blood cells or platelets. Despite the many available treatments for AML, prognosis for patients remains poor and a high unmet need remains. The menin pathway is considered a driver for multiple genetic alterations of the disease, of which NPM1 mutations are among the most common, representing approximately 30% of AML cases. While patients with NPM1-m AML have high response rates to frontline therapy, relapse rates are high and survival outcomes are poor, with only 30% overall survival at 12 months in the R/R setting. Additionally, NPM1 mutations frequently occur with co-mutations in other disease-associated genes, including FLT3, DNMT3A, and IDH1/2, with prognosis heavily influenced by the presence of such co-occurring mutations. Adult patients with NPM1-m AML and select co-mutations and/or R/R disease have a poor prognosis, with median overall survival of only approximately 7.8 months in 2nd line, 5.3 months in 3rd line, and 3.5 months following the 4th line1. There are currently no FDA-approved therapies targeting NPM1-m AML.

About Ziftomenib

Ziftomenib is a potent and selective, oral, investigational menin inhibitor currently in development for the treatment of genetically defined AML patients with high unmet need. In April 2024, ziftomenib received BTD from the FDA for the treatment of adult patients with R/R AML with an NPM1 mutation based on data from Kura’s KOMET-001 clinical trial. Additional information about clinical trials for ziftomenib can be found at www.kuraoncology.com/clinical-trials/#ziftomenib.

Bicara Therapeutics Demonstrates Deep and Durable Responses with Ficerafusp Alfa Plus Pembrolizumab in 1L HPV-Negative R/M HNSCC at ASCO 2025

On June 1, 2025 Bicara Therapeutics Inc. (Nasdaq: BCAX), a clinical-stage biopharmaceutical company committed to bringing transformative bifunctional therapies to patients with solid tumors, reported updated data from the company’s Phase 1/1b clinical trial of ficerafusp alfa in combination with pembrolizumab in patients with first line (1L) recurrent/metastatic (R/M) head and neck squamous cell carcinoma (HNSCC) at the 2025 American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting (Press release, Bicara Therapeutics, JUN 1, 2025, View Source [SID1234653544]). Ficerafusp alfa is a first-in-class bifunctional antibody designed to enhance tumor penetration by breaking barriers in the tumor microenvironment that have challenged the treatment of multiple solid tumor cancers. Specifically, ficerafusp alfa combines two clinically validated targets: an epidermal growth factor receptor (EGFR) directed monoclonal antibody with a domain that binds to human transforming growth factor beta (TGF-β).

"Ficerafusp alfa was specifically designed to impact the tumor stroma and drive tumor penetration with the goal of leading to deeper and more durable responses. We’ve now begun to see this translate clinically, with responses lasting nearly two years and contributing to prolonged overall survival in HPV-negative patients, a population that typically faces poor outcomes due to resistance to available therapies," said David Raben, MD, Chief Medical Officer of Bicara Therapeutics. "The strength of the totality of this updated dataset, including 80% of responders achieving a deep response of at least 80% tumor shrinkage, median duration of response of 21.7 months, median progression free survival of 9.9 months, overall survival of 21.3 months, and a 2-year overall survival rate of 46%, provides compelling support for the continued advancement of FORTIFI-HN01, our pivotal Phase 2/3 trial in the first-line recurrent/metastatic setting."

Key highlights from the presentation include:

In the Phase 1/1b trial, ficerafusp alfa in combination with pembrolizumab resulted in deep and durable anti-tumor activity with improved overall survival (OS) compared to historical benchmarks in patients with 1L R/M human papillomavirus (HPV)-negative HNSCC with a PD-L1 combined positive score (CPS) of ≥1 and with at least 24 months of follow-up.
In the efficacy evaluable human papillomavirus (HPV)-negative population (n=28):
Median duration of response (DOR) of 21.7 months amongst responders (n=15).
Median OS of 21.3 months; 2-year OS rate of 46%.
54% (15/28) confirmed objective response rate (ORR); 64% (18/28) ORR, including an additional three unconfirmed responses.
21% (6/28) complete response rate.
80% (12/15) of responders achieved a deep response (≥80% tumor shrinkage).
Disease control rate of 89% (25/28 patients).
Median progression-free survival of 9.9 months.
Manageable safety profile consistent with previously reported adverse events.
"These latest Phase 1/1b data are impressive, particularly the duration of response, which represents a significant advance over historical controls in patients with HPV-negative recurrent/metastatic head and neck squamous cell carcinoma, including anti-PD-1 combinations with chemotherapy or EGFR inhibitors," said Christine H. Chung, MD, Chair of the Department of Head and Neck-Endocrine Oncology and Deputy Physician-in-Chief at the Moffitt Cancer Center. "This reflects the enhanced ability of ficerafusp alfa to remodel the tumor microenvironment allowing the tumor penetration of immune cells required for deep and durable responses in these patients. In addition, the prolonged overall survival, highlighted by a median OS of 21.3 months, reinforces the potential of ficerafusp alfa to address a critical unmet need by delivering durable anti-tumor responses and meaningful improvements in patients’ quality of life."

About Head and Neck Squamous Cell Carcinoma
Head and neck squamous cell carcinomas (HNSCCs) develop from the mucosal epithelium in the oral cavity, pharynx and larynx and are the most common malignancies that arise in the head and neck. HNSCC is one of the most common cancers in the United States and globally with a rising incidence anticipated to reach one million new global cases annually by 2030. Ten percent of HNSCC patients are diagnosed with metastatic disease and up to 30% develop a recurrence or metastases over time after receiving initial treatment for advanced HNSCC.

Most cases of HNSCC are thought to result from accumulated mutations caused by carcinogenic exposures such as tobacco smoke or HPV infection. Approximately 80% of patients with R/M HNSCC are HPV-negative. These HPV-negative tumors often exhibit a recurrence pattern that is primarily local and are associated with severe morbidities, including fatal tumor bleeding, intense pain, difficulty swallowing, significant weight loss, and cachexia. This highlights a critical unmet need for therapies that have the potential to deliver durable anti-tumor responses, ultimately leading to meaningful improvements in patients’ quality of life.

About Ficerafusp Alfa
Ficerafusp alfa is a first-in-class bifunctional antibody designed to drive tumor penetration by breaking barriers in the tumor microenvironment that have challenged the treatment of multiple solid tumor cancers. Specifically, ficerafusp alfa combines two clinically validated targets: an epidermal growth factor receptor (EGFR) directed monoclonal antibody with a domain that binds to human transforming growth factor beta (TGF-β). Through this targeted mechanism, ficerafusp alfa reverses the fibrotic and immune-excluded tumor microenvironment driven by TGF-β signaling to enable tumor penetration that drives deep and durable responses.

Ficerafusp alfa is currently being evaluated in FORTIFI-HN01, a pivotal Phase 2/3 clinical trial in patients with first line (1L) recurrent/metastatic (R/M) head and neck squamous cell carcinoma (HNSCC).
