WELIREG is a first-in-class oral hypoxia-inducible factor-2 alpha (HIF-2α) inhibitor and is the first and only approved HIF-2α inhibitor in China. This approval is based on objective response rate (ORR) and median duration of response (DOR) results from the Phase 2 LITESPARK-004 trial and is the 17th approval of WELIREG for these patients globally.\n\"This approval of WELIREG brings the first and only systemic therapy to adult patients in China with certain VHL disease-associated tumors who, to date, have not had access to a non-surgical treatment option to help manage manifestations of VHL disease,\" said Dr. Marjorie Green, senior vice president and head of oncology, global clinical development, Merck Research Laboratories. \"We are committed to bringing innovative treatment options to patients in need around the world and are proud to offer eligible adult patients in China a first-in-class HIF-2α inhibitor as a possible treatment option.\"\nIn August 2021, WELIREG was approved in the U.S. for the treatment of adult patients with VHL disease who require therapy for associated RCC, CNS hemangioblastomas or pNET, not requiring immediate surgery. The efficacy of WELIREG was evaluated in LITESPARK-004, an open-label clinical trial in 61 patients with VHL-associated RCC. In the LITESPARK-004 trial, WELIREG showed an ORR of 49% (95% CI, 36-62) in patients with VHL-associated RCC (n=30/61); all responses were partial responses (PR). Median DOR for these patients was not reached, with ongoing responses ranging from 2.8+ to 22.3+ months; among responders, 56% (n=17/30) maintained a response for at least 12 months.\nPatients enrolled in LITESPARK-004 had other VHL-associated tumors, including CNS hemangioblastomas and pNET. In patients with VHL-associated CNS hemangioblastomas (n=24) in this trial, WELIREG showed an ORR of 63% (95% CI, 41-81) (n=15/24), with a complete response (CR) rate of 4% (n=1/24) and a PR rate of 58% (n=14/24). Median DOR for these patients was not reached, with ongoing responses ranging from 3.7+ to 22.3+ months; among responders, 73% (n=11/15) maintained a response for at least 12 months. In patients with VHL-associated pNET (n=12) in this trial, WELIREG showed an ORR of 83% (95% CI, 52-98) (n=10/12), with a CR rate of 17% (n=2/12) and a PR rate of 67% (n=8/12). Median DOR for these patients was not reached, with ongoing responses ranging from 10.8+ to 19.4+ months; among responders, 50% (n=5/10) maintained a response for at least 12 months.\nWELIREG is also approved in the U.S. for the treatment of adult patients with advanced RCC following a programmed death receptor-1 (PD-1) or programmed death-ligand 1 (PD-L1) inhibitor and a vascular endothelial growth factor-tyrosine kinase inhibitor (VEGF-TKI), based on results from the Phase 3 LITESPARK-005 trial. Merck is evaluating WELIREG in advanced RCC and other tumor types through a broad clinical development program, including in Phase 2 and 3 trials evaluating WELIREG as monotherapy and in combination with other medicines.\nAbout LITESPARK-004\nLITESPARK-004 is an open-label Phase 2 trial (ClinicalTrials.gov, NCT03401788) evaluating WELIREG for the treatment of patients with VHL disease who had at least one measurable solid tumor localized to the kidney and who did not require immediate surgery. The study enrolled 61 patients who received WELIREG (120 mg orally once daily) until disease progression or unacceptable toxicity. The primary endpoint is ORR in VHL disease-associated RCC. Secondary endpoints in RCC tumors include disease control rate, DoR, time to response, progression-free survival, time to surgery and safety. Additionally, this study evaluated response rates in other common VHL disease-associated tumors including pNET and CNS hemangioblastomas.\nAbout von Hippel-Lindau disease\nVon Hippel-Lindau disease is a rare genetic disease that impacts an estimated 200,000 people worldwide. Patients with VHL disease are at risk for recurrent, benign blood vessel tumors as well as some cancerous ones. The most commonly occurring tumor is renal cell carcinoma, a form of kidney cancer, which occurs in about 70% of patients with VHL disease.\nAbout WELIREG® (belzutifan) 40 mg tablets, for oral use\nIndications in the U.S.\nCertain von Hippel-Lindau (VHL) disease-associated tumors\nWELIREG (belzutifan) is indicated for the treatment of adult patients with von Hippel-Lindau (VHL) disease who require therapy for associated renal cell carcinoma (RCC), central nervous system (CNS) hemangioblastomas, or pancreatic neuroendocrine tumors (pNET), not requiring immediate surgery.\nAdvanced Renal Cell Carcinoma (RCC)\nWELIREG is indicated for the treatment of adult patients with advanced renal cell carcinoma (RCC) following a programmed death receptor-1 (PD-1) or programmed death ligand 1 (PD-L1) inhibitor and a vascular endothelial growth factor tyrosine kinase inhibitor (VEGF-TKI).\nSelected Safety Information for WELIREG\nWarning: Embryo-Fetal Toxicity\nExposure to WELIREG during pregnancy can cause embryo-fetal harm. Verify pregnancy status prior to the initiation of WELIREG. Advise patients of these risks and the need for effective non-hormonal contraception as WELIREG can render some hormonal contraceptives ineffective.\nAnemia\nWELIREG can cause severe anemia that can require blood transfusion. Monitor for anemia before initiation of, and periodically throughout, treatment. Transfuse patients as clinically indicated. For patients with hemoglobin <8 g/dL, withhold WELIREG until ≥8 g/dL, then resume at the same or reduced dose or permanently discontinue WELIREG, depending on the severity of anemia. For life-threatening anemia or when urgent intervention is indicated, withhold WELIREG until hemoglobin ≥8 g/dL, then resume at a reduced dose or permanently discontinue WELIREG.\nIn LITESPARK-004 (N=61), decreased hemoglobin occurred in 93% of patients with VHL disease and 7% had Grade 3 events. Median time to onset of anemia was 31 days (range: 1 day to 8.4 months).\nThe safety of erythropoiesis-stimulating agents (ESAs) for treatment of anemia in patients with VHL disease treated with WELIREG has not been established.\nIn LITESPARK-005 (n=372), decreased hemoglobin occurred in 88% of patients with advanced RCC and 29% had Grade 3 events. Median time to onset of anemia was 29 days (range: 1 day to 16.6 months). Of the patients with anemia, 22% received transfusions only, 20% received ESAs only, and 12% received both transfusion and ESAs.\nHypoxia\nWELIREG can cause severe hypoxia that may require discontinuation, supplemental oxygen, or hospitalization.\nMonitor oxygen saturation before initiation of, and periodically throughout, treatment. For decreased oxygen saturation with exercise (e.g., pulse oximeter <88% or PaO2 ≤55 mm Hg), consider withholding WELIREG until pulse oximetry with exercise is greater than 88%, then resume at the same or a reduced dose. For decreased oxygen saturation at rest (e.g., pulse oximeter <88% or PaO2 ≤55 mm Hg) or when urgent intervention is indicated, withhold WELIREG until resolved and resume at a reduced dose or discontinue. For life-threatening or recurrent symptomatic hypoxia, permanently discontinue WELIREG. Advise patients to report signs and symptoms of hypoxia immediately to a healthcare provider.\nIn LITESPARK-004, hypoxia occurred in 1.6% of patients.\nIn LITESPARK-005, hypoxia occurred in 15% of patients and 10% had Grade 3 events. Of the patients with hypoxia, 69% were treated with oxygen therapy. Median time to onset of hypoxia was 30.5 days (range: 1 day to 21.1 months).\nEmbryo-Fetal Toxicity\nBased on findings in animals, WELIREG can cause fetal harm when administered to a pregnant woman.\nAdvise pregnant women and females of reproductive potential of the potential risk to the fetus. Advise females of reproductive potential to use effective non-hormonal contraception during treatment with WELIREG and for 1 week after the last dose. WELIREG can render some hormonal contraceptives ineffective. Advise male patients with female partners of reproductive potential to use effective contraception during treatment with WELIREG and for 1 week after the last dose.\nAdverse Reactions\nIn LITESPARK-004, serious adverse reactions occurred in 15% of patients, including anemia, hypoxia, anaphylaxis reaction, retinal detachment, and central retinal vein occlusion (1 patient each).\nWELIREG was permanently discontinued due to adverse reactions in 3.3% of patients for dizziness and opioid overdose (1.6% each).\nDosage interruptions due to an adverse reaction occurred in 39% of patients. Those which required dosage interruption in >2% of patients were fatigue, decreased hemoglobin, anemia, nausea, abdominal pain, headache, and influenza-like illness.\nDose reductions due to an adverse reaction occurred in 13% of patients. The most frequently reported adverse reaction which required dose reduction was fatigue (7%).\nThe most common adverse reactions (≥25%), including laboratory abnormalities, that occurred in patients who received WELIREG were decreased hemoglobin (93%), fatigue (64%), increased creatinine (64%), headache (39%), dizziness (38%), increased glucose (34%), and nausea (31%).\nIn LITESPARK-005, serious adverse reactions occurred in 38% of patients. The most frequently reported serious adverse reactions were hypoxia (7%), anemia (5%), pneumonia (3.5%), hemorrhage (3%), and pleural effusion (2.2%). Fatal adverse reactions occurred in 3.2% of patients who received WELIREG, including sepsis (0.5%) and hemorrhage (0.5%).\nWELIREG was permanently discontinued due to adverse reactions in 6% of patients. Adverse reactions which resulted in permanent discontinuation (≥0.5%) were hypoxia (1.1%) and hemorrhage (0.5%).\nDosage interruptions due to an adverse reaction occurred in 39% of patients. Of the patients who received WELIREG, 28% were 65 to 74 years, and 10% were 75 years and over. Dose interruptions occurred in 48% of patients ≥65 years of age and in 34% of younger patients. Adverse reactions which required dosage interruption in ≥2% of patients were anemia (8%), hypoxia (5%), COVID-19 (4.3%), fatigue (3.2%), and hemorrhage (2.2%).\nDose reductions due to an adverse reaction occurred in 13% of patients. Dose reductions occurred in 18% of patients ≥65 years of age and in 10% of younger patients. The most frequently reported adverse reactions which required dose reduction (≥1.0%) were hypoxia (5%) and anemia (3.2%).\nThe most common (≥25%) adverse reactions, including laboratory abnormalities, were decreased hemoglobin (88%), fatigue (43%), musculoskeletal pain (33%), increased creatinine (34%), decreased lymphocytes (34%), increased alanine aminotransferase (32%), decreased sodium (31%), increased potassium (29%), and increased aspartate aminotransferase (27%).\nDrug Interactions\nCoadministration of WELIREG with inhibitors of UGT2B17 or CYP2C19 increases plasma exposure of belzutifan, which may increase the incidence and severity of adverse reactions. Monitor for anemia and hypoxia and reduce the dosage of WELIREG as recommended.\nCoadministration of WELIREG with CYP3A4 substrates decreases concentrations of CYP3A4 substrates, which may reduce the efficacy of these substrates or lead to therapeutic failures. Avoid coadministration with sensitive CYP3A4 substrates. If coadministration cannot be avoided, increase the sensitive CYP3A4 substrate dosage in accordance with its Prescribing Information. Coadministration of WELIREG with hormonal contraceptives may lead to contraceptive failure or an increase in breakthrough bleeding.\nLactation\nBecause of the potential for serious adverse reactions in breastfed children, advise women not to breastfeed during treatment with WELIREG and for 1 week after the last dose.\nFemales and Males of Reproductive Potential\nWELIREG can cause fetal harm when administered to a pregnant woman. Verify the pregnancy status of females of reproductive potential prior to initiating treatment with WELIREG.\nUse of WELIREG may reduce the efficacy of hormonal contraceptives. Advise females of reproductive potential to use effective non-hormonal contraception during treatment with WELIREG and for 1 week after the last dose. Advise males with female partners of reproductive potential to use effective contraception during treatment with WELIREG and for 1 week after the last dose.\nBased on findings in animals, WELIREG may impair fertility in males and females of reproductive potential and the reversibility of this effect is unknown.\nPediatric Use\nSafety and effectiveness of WELIREG in pediatric patients under 18 years of age have not been established.\nMerck’s focus on cancer\nEvery day, we follow the science as we work to discover innovations that can help patients, no matter what stage of cancer they have.
