"ASCO is a powerful platform for highlighting progress in cancer care, and we’re proud to contribute 23 accepted abstracts that reflect our mission to improve outcomes for more patients around the world," said Mark Lanasa, M.D., Ph.D., Chief Medical Officer, Solid Tumors at BeiGene. "From long-term follow-up results for BRUKINSA in CLL to first-time clinical data for two promising breast cancer assets, our presentations this year speak to the depth and momentum of our oncology portfolio — and our commitment to delivering transformative medicines across a range of cancers."

Presentations feature the impressive clinical profile of BRUKINSA (zanubrutinib) across broad patient populations; notable highlights include:

Long-term data from SEQUOIA Arm C, which evaluated BRUKINSA in patients with treatment naïve (TN) chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) with del(17p) mutations.
First results from the full population from Arm D of the SEQUOIA study, which evaluated BRUKINSA plus venetoclax in patients with TN CLL/SLL with and without del (17p) and/or TP53 mutation.
Robust analyses across clinical trials and real-world evidence that deepen understanding of treatment patterns, safety, and outcomes in CLL and mantle cell lymphoma (MCL).
Highlights include new comparative efficacy data for BRUKINSA versus fixed-duration regimens based on a network meta-analysis, as well as real-world studies evaluating BTK inhibitor use, treatment disparities, and clinical outcomes across diverse patient populations.
Early phase data includes never-before-presented clinical data from BeiGene’s emerging breast cancer pipeline; notable highlights include:

Preliminary results of the dose escalation study for BG-C9074, a topoisomerase inhibitor antibody-drug conjugate (ADC) targeting the B7-H4 protein, in patients with advanced solid tumors, including breast cancer.
Early clinical activity for BG-68501, a cyclin-dependent kinase-2 inhibitor (CDK2i), in HR+/HER2- breast cancer patients with prior CDK4/6i exposure, supporting its development as a next-line option for tumors with CDK2 dependency.
Results from the final analysis of the RATIONALE-213 study demonstrate that, using a PET-guided approach, TEVIMBRA plus chemotherapy or chemoradiotherapy showed promising efficacy and a tolerable safety profile in the neoadjuvant setting for resectable esophageal squamous cell carcinoma (ESCC), in both patients who responded and did not respond to preoperative chemotherapy. This adds further evidence to the PD-1 inhibitor’s established ability to deliver clinically meaningful efficacy benefits as well as its consistent safety profile.

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 of patients with relapsed / refractory chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL).

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.

About TEVIMBRA (tislelizumab-jsgr)

TEVIMBRA is a uniquely designed humanized immunoglobulin G4 (IgG4) anti-programmed cell death protein 1 (PD-1) monoclonal antibody with high affinity and binding specificity against PD-1. It is designed to minimize binding to Fc-gamma (Fcγ) receptors on macrophages, helping the body’s immune cells detect and fight tumors.

TEVIMBRA is the foundational asset of BeiGene’s solid tumor portfolio and has shown potential across multiple tumor types and disease settings. The global TEVIMBRA clinical development program includes almost 14,000 patients enrolled to date in 35 countries and regions across 70 trials, including 21 registration-enabling studies. TEVIMBRA is approved in 46 markets, and more than 1.5 million patients have been treated globally.

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.

Please see full U.S. Prescribing Information including U.S. Patient Information.

U.S. Indication and Important Safety Information for TEVIMBRA (tislelizumab-jsgr) injection

IMPORTANT SAFETY INFORMATION

WARNINGS AND PRECAUTIONS

Severe and Fatal Immune-Mediated Adverse Reactions

TEVIMBRA is a monoclonal antibody that belongs to a class of drugs that bind to either the programmed death receptor-1 (PD-1) or PD-ligand 1 (PD-L1), blocking the PD-1/PD-L1 pathway, thereby removing inhibition of the immune response, potentially breaking peripheral tolerance and inducing immune-mediated adverse reactions.

Immune-mediated adverse reactions, which may be severe or fatal, can occur in any organ system or tissue. Immune-mediated adverse reactions can occur at any time after starting treatment with a PD-1/PD-L1 blocking antibody. While immune-mediated adverse reactions usually manifest during treatment with PD-1/PD-L1 blocking antibodies, immune-mediated adverse reactions can also manifest after discontinuation of PD-1/PD-L1 blocking antibodies. Important immune-mediated adverse reactions listed here may not include all possible severe and fatal immune-mediated reactions.

Early identification and management of immune-mediated adverse reactions are essential to ensure safe use of PD-1/PD-L1 blocking antibodies. Monitor patients closely for symptoms and signs that may be clinical manifestations of underlying immune-mediated adverse reactions. Evaluate liver enzymes, creatinine, and thyroid function at baseline and periodically during treatment. In cases of suspected immune-mediated adverse reactions, initiate appropriate workup to exclude alternative etiologies, including infection. Institute medical management promptly, including specialty consultation as appropriate.

Withhold or permanently discontinue TEVIMBRA depending on severity. In general, if TEVIMBRA requires interruption or discontinuation, administer systemic corticosteroid therapy (1 to 2 mg/kg/day prednisone or equivalent) until improvement to Grade 1 or less. Upon improvement to Grade 1 or less, initiate corticosteroid taper and continue to taper over at least 1 month. Consider administration of other systemic immunosuppressants in patients whose immune-mediated adverse reactions are not controlled with corticosteroids.

Immune-Mediated Pneumonitis

TEVIMBRA can cause immune-mediated pneumonitis, which can be fatal. In patients treated with other PD-1/PD-L1 blocking antibodies, the incidence of pneumonitis is higher in patients who have received prior thoracic radiation.

Immune-mediated pneumonitis occurred in 4.9% (96/1972) of patients receiving TEVIMBRA, including fatal (0.1%), Grade 4 (0.3%), Grade 3 (1.6%) and Grade 2 (1.9%) adverse reactions. Pneumonitis led to permanent discontinuation of TEVIMBRA in 38 (1.9%) patients and withholding of TEVIMBRA in 32 (1.6%) patients.

Seventy-four (77.1%) of the 96 patients received systemic corticosteroids. Sixty-five (67.7%) of the 96 patients received high-dose systemic corticosteroids. Immune-mediated pneumonitis resolved in 50% of the 96 patients. Of the 32 patients in whom TEVIMBRA was withheld for pneumonitis, 20 (62.5%) reinitiated TEVIMBRA after symptom improvement; of these, 2 (10%) patients had recurrence of pneumonitis.

Immune-Mediated Colitis

TEVIMBRA can cause immune-mediated colitis, which can be fatal. Cytomegalovirus (CMV) infection/reactivation has been reported in patients with corticosteroid-refractory immune-mediated colitis treated with PD-1/PD-L1 blocking antibodies. In cases of corticosteroid-refractory colitis, consider repeating infectious workup to exclude alternative etiologies.

Immune-mediated colitis occurred in 0.8% (16/1972) of patients receiving TEVIMBRA, including Grade 3 (0.3%) and Grade 2 (0.4%) adverse reactions. Colitis led to permanent discontinuation of TEVIMBRA in 4 (0.2%) patients and withholding of TEVIMBRA in 5 (0.3%) patients. Twelve (75%) of the 16 patients received systemic corticosteroids. Eight (50%) of the 16 patients received high-dose systemic corticosteroids. Two (12.5%) of the 16 patients received immunosuppressive treatment. Immune-mediated colitis resolved in 93.8% of the 16 patients. All 5 patients in whom TEVIMBRA was withheld for colitis reinitiated TEVIMBRA after symptom improvement; of these, none of the patients had recurrence of colitis.

Immune-Mediated Hepatitis

TEVIMBRA can cause immune-mediated hepatitis, which can be fatal.

Immune-mediated hepatitis occurred in 1.2% (24/1972) of patients receiving TEVIMBRA, including fatal (0.1%), Grade 4 (0.2%), Grade 3 (0.5%) and Grade 2 (0.4%) adverse reactions. Immune-mediated hepatitis led to permanent discontinuation in 3 (0.2%) patients and withholding of TEVIMBRA in 13 (0.7%) patients. Eighteen (75%) of the 24 patients received systemic corticosteroids. Thirteen (54.2%) of the 24 patients received high-dose systemic corticosteroids. Two patients (8.3%) of the 24 patients received immunosuppressive treatment. Immune-mediated hepatitis resolved in 70.8% of the 24 patients. Of the 13 patients in whom TEVIMBRA was withheld for hepatitis, 7 (53.8%) reinitiated TEVIMBRA after symptom improvement; of these, none of the patients had recurrence of hepatitis.

Immune-Mediated Endocrinopathies

Adrenal Insufficiency

TEVIMBRA can cause immune-mediated adrenal insufficiency. For Grade 2 or higher adrenal insufficiency, initiate symptomatic treatment, including hormone replacement as clinically indicated. Withhold TEVIMBRA depending on severity.

Immune-mediated adrenal insufficiency occurred in 0.4% (8/1972) of patients receiving TEVIMBRA, including Grade 4 (0.1%), Grade 3 (0.1%) and Grade 2 (0.3%) adverse reactions. Adrenal insufficiency did not lead to permanent discontinuation of TEVIMBRA. TEVIMBRA was withheld in 7 (0.4%) patients. All 8 patients received systemic corticosteroids. Three (37.5%) of the 8 patients received high-dose systemic corticosteroids. Adrenal insufficiency resolved in 25% of the 8 patients. Of the 7 patients in whom TEVIMBRA was withheld for adrenal insufficiency, 5 (71.4%) reinitiated TEVIMBRA after symptom improvement; of these, none of the patients had recurrence of adrenal insufficiency.

Hypophysitis

TEVIMBRA can cause immune-mediated hypophysitis. Hypophysitis can present with acute symptoms associated with mass effect such as headache, photophobia, or visual field defects. Hypophysitis can cause hypopituitarism. Initiate hormone replacement as clinically indicated. Withhold or permanently discontinue TEVIMBRA depending on severity.

Hypophysitis/hypopituitarism occurred in 0.2% (4/1972) of patients receiving TEVIMBRA, including a Grade 2 (0.2%) adverse reaction. No TEVIMBRA treatment discontinuation was required, while treatment was withheld in 1 (0.1%) patient. Three (75%) of the 4 patients received systemic corticosteroids. One (25%) of the 4 patients received high-dose systemic corticosteroids. Hypophysitis/hypopituitarism did not resolve in the 4 patients. For the 1 patient where TEVIMBRA was withheld for hypophysitis/hypopituitarism, there was no recurrence of hypophysitis/hypopituitarism.

Thyroid Disorders

TEVIMBRA can cause immune-mediated thyroid disorders. Thyroiditis can present with or without endocrinopathy. Hypothyroidism can follow hyperthyroidism. Initiate hormone replacement for hypothyroidism or institute medical management of hyperthyroidism as clinically indicated. Withhold or permanently discontinue TEVIMBRA depending on severity.

Thyroiditis: Immune-mediated thyroiditis occurred in 1.2% (24/1972) of patients receiving TEVIMBRA, including Grade 2 (0.5%) adverse reactions. Thyroiditis did not lead to permanent discontinuation of TEVIMBRA. TEVIMBRA was withheld in 3 (0.2%) patients. Two (8.3%) of the 24 patients received systemic corticosteroids. Thyroiditis resolved in 41.7% of the 24 patients. All three patients in whom TEVIMBRA was withheld for thyroiditis reinitiated TEVIMBRA after symptom improvement; of these, none of the patients had recurrence of thyroiditis.

Hyperthyroidism: Immune-mediated hyperthyroidism occurred in 4.8% (95/1972) of patients receiving TEVIMBRA, including Grade 3 (0.1%) and Grade 2 (0.9%) adverse reactions. Hyperthyroidism led to the permanent discontinuation of TEVIMBRA in 1 (0.1%) patient and withholding of TEVIMBRA in 4 (0.2%) patients. One (1.1%) of the 95 patients received systemic corticosteroids. Hyperthyroidism resolved in 75.8% of the 95 patients. Of the 4 patients in whom TEVIMBRA was withheld for hyperthyroidism, 3 (75%) reinitiated TEVIMBRA after symptom improvement; of these, none of the patients had recurrence of hyperthyroidism.

Hypothyroidism: Immune-mediated hypothyroidism occurred in 12.7% (250/1972) of patients receiving TEVIMBRA, including Grade 4 (0.1%) and Grade 2 (6.8%) adverse reactions. TEVIMBRA was not permanently discontinued in any patient, while treatment was withheld in 7 (0.4%) patients. Two (0.8%) of the 250 patients received systemic corticosteroids and 158 patients (63.2%) received hormone replacement therapy. Hypothyroidism resolved in 31.6% of the 250 patients. The majority (51.6%) of patients with hypothyroidism required long-term thyroid hormone replacement. Of the 7 patients in whom TEVIMBRA was withheld for hypothyroidism, 6 (85.7%) reinitiated TEVIMBRA after symptom improvement; of these, none of the patients had recurrence of hypothyroidism.

Type 1 Diabetes Mellitus, which can present with Diabetic Ketoacidosis

Diabetes mellitus has been reported with PD-1/PD-L1 blocking antibodies. Monitor patients for hyperglycemia or other signs and symptoms of diabetes. Initiate treatment with insulin as clinically indicated. Withhold or permanently discontinue TEVIMBRA depending on severity.

Diabetes mellitus occurred in 0.9% (18/1972) of patients receiving TEVIMBRA, including Grade 4 (0.1%), Grade 3 (0.4%) and Grade 2 (0.4%) adverse reactions. TEVIMBRA was permanently discontinued in 3 (0.2%) patients and TEVIMBRA treatment was withheld in 3 (0.2%) patients. Twelve (66.7%) patients received insulin therapy for diabetes mellitus. Diabetes mellitus resolved in 27.8% of the 18 patients. Of the 3 patients in whom TEVIMBRA was withheld for diabetes mellitus, none of the patients reinitiated TEVIMBRA after symptom improvement.

Immune-Mediated Nephritis with Renal Dysfunction

TEVIMBRA can cause immune-mediated nephritis, which can be fatal.

Immune-mediated nephritis with renal dysfunction occurred in 0.3% (5/1972) of patients receiving TEVIMBRA, including Grade 3 (0.1%) and Grade 2 (0.2%) adverse reactions. TEVIMBRA was permanently discontinued in 1 (0.1%) patient and treatment was withheld in 3 (0.2%) patients. Three (60%) of the 5 patients received systemic corticosteroids. All 3 (60%) of the 5 patients received high-dose systemic corticosteroids. Nephritis with renal dysfunction resolved in 40.0% of the 5 patients. Of the 3 patients in whom TEVIMBRA was withheld for nephritis, 2 (66.7%) reinitiated TEVIMBRA after symptom improvement and one (50%) patient had recurrence of nephritis.

Immune-Mediated Dermatologic Adverse Reactions

TEVIMBRA can cause immune-mediated rash or dermatitis. Cases of severe cutaneous adverse reactions (SCARs), including exfoliative dermatitis, Stevens-Johnson Syndrome (SJS), and toxic epidermal necrolysis (TEN), have been reported, some with fatal outcome. Topical emollients and/or topical corticosteroids may be adequate to treat mild to moderate non-exfoliative rashes. Withhold or permanently discontinue TEVIMBRA depending on severity.

Immune-mediated dermatologic adverse reactions occurred in 15.3% (301/1972) of patients receiving TEVIMBRA, including Grade 4 (0.1%), Grade 3 (0.9%) and Grade 2 (3.5%) adverse reactions.

Nervous System: Meningitis, encephalitis, myelitis and demyelination, myasthenic syndrome/myasthenia gravis (including exacerbation), Guillain-Barré syndrome, nerve paresis, autoimmune neuropathy.

Ocular: Uveitis, iritis, and other ocular inflammatory toxicities can occur. Some cases can be associated with retinal detachment. Various grades of visual impairment, including blindness, can occur. If uveitis occurs in combination with other immune-mediated adverse reactions, consider a Vogt-Koyanagi-Harada-like syndrome, as this may require treatment with systemic steroids to reduce the risk of permanent vision loss.

Gastrointestinal: Pancreatitis including increases in serum amylase and lipase levels, gastritis, duodenitis.

Musculoskeletal and Connective Tissue: Polymyositis, rhabdomyolysis and associated sequelae including renal failure.

Endocrine: Hypoparathyroidism.

Other (Hematologic/Immune): Hemolytic anemia, aplastic anemia, hemophagocytic lymphohistiocytosis, systemic inflammatory response syndrome, histiocytic necrotizing lymphadenitis (Kikuchi lymphadenitis), sarcoidosis, immune thrombocytopenic purpura, solid organ transplant rejection, other transplant (including corneal graft) rejection.

Infusion-Related Reactions

TEVIMBRA can cause severe or life-threatening infusion-related reactions. Infusion-related reactions occurred in 5% (99/1972) patients receiving TEVIMBRA, including Grade 3 or higher (0.2%) reactions. Monitor patients for signs and symptoms of infusion-related reactions.

Slow the rate of infusion for mild (Grade 1) and interrupt the infusion for moderate (Grade 2) infusion-related reactions. For severe (Grade 3) or life-threatening (Grade 4) infusion-related reactions, stop infusion and permanently discontinue TEVIMBRA.

Complications of Allogeneic HSCT

Fatal and other serious complications can occur in patients who receive allogeneic hematopoietic stem cell transplantation (HSCT) before or after being treated with a PD-1/PD-L1 blocking antibody. Transplant-related complications include hyperacute graft-versus-host disease (GVHD), acute GVHD, chronic GVHD, hepatic veno-occlusive disease after reduced intensity conditioning, and steroid-requiring febrile syndrome (without an identified infectious cause). These complications may occur despite intervening therapy between PD-1/PD-L1 blockade and allogeneic HSCT.

Follow patients closely for evidence of transplant-related complications and intervene promptly. Consider the benefit versus risks of treatment with a PD-1/PD-L1 blocking antibody prior to or after an allogeneic HSCT.

Embryo-Fetal Toxicity

Based on its mechanism of action, TEVIMBRA can cause fetal harm when administered to a pregnant woman. Animal studies have demonstrated that inhibition of the PD-1/PD-L1 pathway can lead to increased risk of immune-mediated rejection of the developing fetus resulting in fetal death. Advise pregnant women of the potential risk to a fetus. Advise females of reproductive potential to use effective contraception during treatment with TEVIMBRA and for 4 months after the last dose.

Astellas and Pfizer’s XTANDI™ (enzalutamide) Shows Long-Term Overall Survival in Metastatic Hormone-Sensitive Prostate Cancer

On May 22, 2025 Astellas Pharma Inc. (TSE: 4503, President and CEO: Naoki Okamura, "Astellas") and Pfizer Inc. (NYSE: PFE) reported longer-term follow-up results from an open-label extension of the Phase 3 ARCHES (NCT02677896) study, reporting a five-year follow up of overall survival (OS) benefits and a 30% reduction in the risk of death in men with metastatic hormone-sensitive prostate cancer (mHSPC) treated with XTANDI (enzalutamide), an androgen receptor pathway inhibitor (ARPI), plus androgen deprivation therapy (ADT) compared to placebo plus ADT (Press release, Astellas, MAY 22, 2025, View Source [SID1234653294]). These data will be presented during an oral presentation (Abstract #5005) at the American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting in Chicago (Tuesday, June 3, 9:45 a.m.- 12:45 p.m. US CT).

"Historically, the likelihood of survival at five years for men with metastatic hormone-sensitive prostate cancer was low, but with advancements in initial treatment intensification like what we’ve seen with XTANDI, this is now becoming the standard," said Andrew J. Armstrong, MD, ScM, Director of Research at the Center for Prostate & Urologic Cancers, Duke Cancer Institute, Durham, NC, and ARCHES primary investigator. "In our five-year follow up of the global ARCHES trial, two-thirds of men are now surviving five years, representing a 13% absolute and 30% relative improvement over standard hormonal therapy alone, with benefits in patients with high and low disease burden that are meaningful to our patients."

In patients with high-volume disease (HR: 0.70; 95% CI: 0.56-0.88) a 36-month improvement in median OS was observed. Additional clinically relevant subgroups of patients were evaluated, showing consistently improved survival: low-volume disease (HR: 0.71; 95% CI, 0.49-1.05); patients who had previously received docetaxel therapy (HR: 0.67; 95% CI, 0.43- 1.05) and those who had not received prior docetaxel therapy (HR: 0.71; 95% CI, 0.57-0.88). The incidence of treatment-emergent adverse events in the five-year follow-up is consistent with prior ARCHES analyses and no new safety signals were identified.

"The survival benefits of intervention with XTANDI in advanced prostate cancer are well-recognized," added Shontelle Dodson, Executive Vice President, Head of Medical Affairs, Astellas. "The collective – and growing – body of data for XTANDI continues to reinforce its long-term efficacy and patient impact in prostate cancer, including in the metastatic setting, and shows that XTANDI is changing the trajectory of those living with the disease."

These results of the five-year follow-up from the ARCHES study will be submitted for publication in a peer-reviewed journal in the near future.

"Until recently, patients with metastatic hormone-sensitive prostate cancer faced a poor prognosis, particularly in advanced stages, often due to treatment resistance," said Johanna Bendell, M.D., Oncology Chief Development Officer, Pfizer. "As the only androgen receptor inhibitor demonstrating sustained five-year survival in this patient population, these data further reinforce XTANDI combined with androgen deprivation therapy as the standard-of-care for treating this advanced disease."

In addition to five-year data from the follow-up ARCHES study, eight-year data from the ENZAMET study assessing outcomes of enzalutamide versus non-steroidal anti-androgen (NSAA) – both plus testosterone suppression with or without docetaxel – in mHSPC will also be presented during a poster session at ASCO (Free ASCO Whitepaper) (Monday, June 2, 9:00 a.m. US CT). This independent, Phase 3 trial sponsored by the University of Sydney (NCT02446405), led by the Australian and New Zealand Urogenital and Prostate Cancer Trials Group Limited (ANZUP), demonstrated a reduction in risk of death in men with mHSPC.

"Data from the eight-year follow-up of XTANDI are highly encouraging, as they show the progression-free survival and overall survival benefits are sustained out to at least eight years," said Christopher Sweeney, MBBS, DHS, FRACP, ANZUP Cancer Trials Group Limited, Sydney, Australia, and ENZAMET follow-up primary investigator. "These results further support the value of XTANDI as a treatment regimen for metastatic hormone-sensitive prostate cancer."

With a median follow-up of 98 months, patients with mHSPC were treated with XTANDI plus testosterone suppression or NSAA plus testosterone suppression, each group with or without docetaxel. The median OS in the XTANDI group was 8.0 years and 5.8 years in the NSAA group (HR: 0.73; 95% CI, 0.63-0.86). OS at 96 months was 50% with XTANDI and 40% for NSAA; progression-free survival (PFS) also favored XTANDI over NSAA (HR: 0.49; 95% CI, 0.42-0.57). Prostate cancer accounted for 468 of all 622 deaths and were less frequent among those assigned XTANDI than NSAA (207 versus 261). Other causes accounted for a total of 154 deaths and were similarly frequent among those assigned XTANDI versus NSAA (78 versus 76). Mean duration of treatment was longer for XTANDI (58 months) than NSAA (36 months), with 33% remaining on XTANDI and 88% of these patients remained at the full dose of 160 mg.

XTANDI is currently approved in more than 90 countries, including in the United States, European Union and Japan. Since its initial approval in 2012, over one million patients have been treated with XTANDI globally.1***

About Metastatic Hormone-Sensitive Prostate Cancer (mHSPC)
Metastatic hormone-sensitive prostate cancer, also known as metastatic castration-sensitive prostate cancer, refers to prostate cancer that still responds to hormonal therapy and has spread outside of the prostate gland to other parts of the body, such as the lymph nodes, bones, lungs and liver.2

About the ARCHES Study
The Phase 3, randomized, double-blind, placebo-controlled, multi-national trial enrolled 1,150 patients with metastatic hormone-sensitive prostate cancer (mHSPC) at sites in the United States, Canada, Europe, South America and the Asia-Pacific region. Patients in the ARCHES trial were randomized to receive XTANDI 160 mg daily or placebo and continued on a luteinizing hormone-releasing hormone (LHRH) agonist or antagonist or had a history of bilateral orchiectomy. The ARCHES trial included patients with both low- and high-volume disease and both newly diagnosed patients with mHSPC and patients who had prior definitive therapy and subsequently developed metastatic disease. The trial also included some patients who had received recent treatment with docetaxel for mHSPC, but whose disease had not progressed. The primary endpoint of the trial was radiographic progression-free survival (rPFS), defined as the time from randomization to the first objective evidence of radiographic disease progression as assessed by central review, or death within 24 weeks of treatment discontinuation.

In addition to the key secondary endpoint of overall survival at final analysis, a post hoc 5-year analysis was executed with the intent to further quantify long-term overall survival at a clinically meaningful landmark follow-up of five years.

For more information on the global ARCHES trial, go to www.clinicaltrials.gov.

About ENZAMET
ENZAMET is a trial led by ANZUP Cancer Trials Group Limited in collaboration with the NHMRC (National Health and Medical Research Council) Clinical Trials Centre at the University of Sydney with trial sites in Australia, Canada, Ireland, New Zealand, UK and United States. The trial evaluates the potential of enzalutamide plus androgen deprivation therapy (ADT) versus a conventional non-steroidal anti androgen (NSAA) plus ADT in 1,125 men with mHSPC. The primary endpoint for the trial is overall survival (OS). Additional details about ENZAMET (NCT02446405) are available on www.clinicaltrials.gov. Astellas provided funding and support for the ENZAMET trial.

About XTANDI (enzalutamide)
XTANDI (enzalutamide) is an androgen receptor signaling inhibitor. XTANDI is a standard of care and has received regulatory approvals in one or more countries around the world for use in men with metastatic hormone-sensitive prostate cancer (mHSPC), metastatic castration-resistant prostate cancer (mCRPC), non-metastatic castration-resistant prostate cancer (nmCRPC) and non-metastatic hormone-sensitive prostate cancer (nmHSPC) with high-risk biochemical recurrence (BCR). XTANDI is currently approved for one or more of these indications in more than 90 countries, including in the United States, European Union and Japan. Over one million patients have been treated with XTANDI globally.1

About XTANDI (enzalutamide) and Important Safety Information

XTANDI (enzalutamide) is indicated for the treatment of patients with:

castration-resistant prostate cancer (CRPC)
metastatic castration-sensitive prostate cancer (mCSPC)
nonmetastatic castration sensitive prostate cancer (nmCSPC) with biochemical recurrence at high risk for metastasis (high-risk BCR)
Important Safety Information

Warnings and Precautions
Seizure occurred in 0.6% of patients receiving XTANDI in eight randomized clinical trials. In a study of patients with predisposing factors for seizure, 2.2% of XTANDI-treated patients experienced a seizure. It is unknown whether anti-epileptic medications will prevent seizures with XTANDI. Patients in the study had one or more of the following predisposing factors: use of medications that may lower the seizure threshold, history of traumatic brain or head injury, history of cerebrovascular accident or transient ischemic attack, and Alzheimer’s disease, meningioma, or leptomeningeal disease from prostate cancer, unexplained loss of consciousness within the last 12 months, history of seizure, presence of a space occupying lesion of the brain, history of arteriovenous malformation, or history of brain infection. Advise patients of the risk of developing a seizure while taking XTANDI and of engaging in any activity where sudden loss of consciousness could cause serious harm to themselves or others. Permanently discontinue XTANDI in patients who develop a seizure during treatment.

Posterior Reversible Encephalopathy Syndrome (PRES) There have been reports of PRES in patients receiving XTANDI. PRES is a neurological disorder that can present with rapidly evolving symptoms including seizure, headache, lethargy, confusion, blindness, and other visual and neurological disturbances, with or without associated hypertension. A diagnosis of PRES requires confirmation by brain imaging, preferably MRI. Discontinue XTANDI in patients who develop PRES.

Hypersensitivity reactions, including edema of the face (0.5%), tongue (0.1%), or lip (0.1%) have been observed with XTANDI in eight randomized clinical trials. Pharyngeal edema has been reported in post-marketing cases. Advise patients who experience any symptoms of hypersensitivity to temporarily discontinue XTANDI and promptly seek medical care. Permanently discontinue XTANDI for serious hypersensitivity reactions.

Ischemic Heart Disease In the combined data of five randomized, placebo-controlled clinical studies, ischemic heart disease occurred more commonly in patients on the XTANDI arm compared to patients on the placebo arm (3.5% vs 2%). Grade 3-4 ischemic events occurred in 1.8% of patients on XTANDI versus 1.1% on placebo. Ischemic events led to death in 0.4% of patients on XTANDI compared to 0.1% on placebo. Monitor for signs and symptoms of ischemic heart disease. Optimize management of cardiovascular risk factors, such as hypertension, diabetes, or dyslipidemia. Discontinue XTANDI for Grade 3-4 ischemic heart disease.

Falls and Fractures occurred in patients receiving XTANDI. Evaluate patients for fracture and fall risk. Monitor and manage patients at risk for fractures according to established treatment guidelines and consider use of bone-targeted agents. In the combined data of five randomized, placebo-controlled clinical studies, falls occurred in 12% of patients treated with XTANDI compared to 6% of patients treated with placebo. Fractures occurred in 13% of patients treated with XTANDI and in 6% of patients treated with placebo.

Embryo-Fetal Toxicity The safety and efficacy of XTANDI have not been established in females. XTANDI can cause fetal harm and loss of pregnancy when administered to a pregnant female. Advise males with female partners of reproductive potential to use effective contraception during treatment with XTANDI and for 3 months after the last dose of XTANDI.

Dysphagia or Choking Severe dysphagia or choking, including events that could be life-threatening requiring medical intervention or fatal, can occur due to XTANDI product size. Advise patients to take each capsule or tablet whole with a sufficient amount of water to ensure that all medication is successfully swallowed. Consider use of a smaller tablet size of XTANDI in patients who have difficulty swallowing. Discontinue XTANDI for patients who cannot swallow capsules or tablets.

Adverse Reactions (ARs)
In the data from the five randomized placebo-controlled trials, the most common ARs (≥ 10%) that occurred more frequently (≥ 2% over placebo) in XTANDI-treated patients were musculoskeletal pain, fatigue, hot flush, constipation, decreased appetite, diarrhea, hypertension, hemorrhage, fall, fracture, and headache. In the bicalutamide-controlled study, the most common ARs (≥ 10%) reported in XTANDI-treated patients were asthenia/fatigue, back pain, musculoskeletal pain, hot flush, hypertension, nausea, constipation, diarrhea, upper respiratory tract infection, and weight loss.

In ARCHES, the placebo-controlled study of metastatic CSPC (mCSPC) patients, Grade 3 or higher ARs were reported in 24% of XTANDI-treated patients. Permanent discontinuation due to ARs as the primary reason was reported in 5% of XTANDI patients and 4% of placebo patients.

Lab Abnormalities: Lab abnormalities that occurred in ≥ 5% of patients, and more frequently (> 2%) in the XTANDI arm compared to placebo in the pooled, randomized, placebo-controlled studies are hemoglobin decrease, neutrophil count decreased, white blood cell decreased, hyperglycemia, hypermagnesemia, hyponatremia, hypophosphatemia, and hypercalcemia.

Hypertension: In the combined data from five randomized placebo-controlled clinical trials, hypertension was reported in 14.2% of XTANDI patients and 7.4% of placebo patients. Hypertension led to study discontinuation in < 1% of patients in each arm.

Drug Interactions
Effect of Other Drugs on XTANDI Avoid coadministration with strong CYP2C8 inhibitors. If coadministration cannot be avoided, reduce the dosage of XTANDI.

Avoid coadministration with strong CYP3A4 inducers. If coadministration cannot be avoided, increase the dosage of XTANDI.

Effect of XTANDI on Other Drugs Avoid coadministration with certain CYP3A4, CYP2C9, and CYP2C19 substrates for which minimal decrease in concentration may lead to therapeutic failure of the substrate. If coadministration cannot be avoided, increase the dosage of these substrates in accordance with their Prescribing Information. In cases where active metabolites are formed, there may be increased exposure to the active metabolites.
