Perioperative IMFINZI® (durvalumab) plus neoadjuvant enfortumab vedotin granted Priority Review in the US for patients with muscle-invasive bladder cancer
WILMINGTON, Del.--( BUSINESS WIRE)--AstraZeneca’s supplemental Biologics License Application (sBLA) for IMFINZI ® (durvalumab) in combination with enfortumab vedotin (EV) has been accepted and granted Priority Review in the US for the treatment of patients with muscle-invasive bladder cancer (MIBC) who are ineligible for or have declined cisplatin-based chemotherapy.
The Food and Drug Administration (FDA) grants Priority Review to applications for medicines that, if approved, would offer significant improvements over available treatment options by demonstrating safety or efficacy improvements, preventing serious conditions or enhancing patient compliance. 1 The Prescription Drug User Fee Act (PDUFA) date, the FDA action date for its regulatory decision, is anticipated during the fourth quarter of 2026.
Approximately one in four patients with bladder cancer has muscle-invasive disease, where the tumor invades the muscle wall of the bladder, without distant metastases. 2,3 As many as 50% of patients are ineligible for cisplatin-based chemotherapy due to impaired renal function or comorbidities. 4,5 The standard treatment for these patients has historically been radical cystectomy alone but, despite undergoing this major surgery, patients experience high rates of recurrence and have a poor prognosis. 4-6
Susan Galbraith, Executive Vice President, Oncology Haematology R&D, AstraZeneca, said: “This Priority Review reinforces the potential of IMFINZI to become the immunotherapy backbone treatment for muscle-invasive bladder cancer, where patients face high rates of recurrence despite bladder removal surgery. If approved, this would be the first perioperative regimen with enfortumab vedotin given only before surgery; a potentially new standard of care offering practice-changing efficacy and tolerability in this curative-intent setting.”
The sBLA is based on results from the VOLGA Phase III trial, which will be presented at a forthcoming medical meeting. In a planned interim analysis, perioperative treatment with IMFINZI in combination with neoadjuvant EV demonstrated statistically significant and clinically meaningful improvements in event-free survival (EFS) and overall survival (OS) versus radical cystectomy (surgery to remove the bladder) with or without approved adjuvant treatment.
The safety and tolerability of IMFINZI plus EV was consistent with the known safety profiles of the individual medicines, with no new safety signals identified.
Regulatory applications are currently under review in the EU, Japan and several other countries based on the results of the VOLGA trial.
IMFINZI is approved in over 50 countries for patients with cisplatin-eligible MIBC, based on the NIAGARA Phase III trial. IMFINZI in combination with Bacillus Calmette-Guérin (BCG) induction and maintenance therapy is approved in the US, Japan and other countries for patients with BCG-naïve, high-risk non-muscle-invasive bladder cancer, based on the POTOMAC Phase III trial. In July 2026, positive high-level results from the NILE Phase III trial showed IMFINZI plus chemotherapy demonstrated a statistically significant and clinically meaningful improvement in OS versus chemotherapy as 1st-line treatment for patients with PD-L1 high unresectable, locally advanced or metastatic urothelial cancer.
IMPORTANT SAFETY INFORMATION
There are no contraindications for IMFINZI ® (durvalumab) or IMJUDO ® (tremelimumab-actl).
Severe and Fatal Immune-Mediated Adverse Reactions
Important immune-mediated adverse reactions listed under Warnings and Precautions may not include all possible severe and fatal immune-mediated 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 or after discontinuation. Monitor patients closely for symptoms and signs that may be clinical manifestations of underlying immune-mediated adverse reactions. Evaluate clinical chemistries including liver enzymes, creatinine, adrenocorticotropic hormone (ACTH) level, and thyroid function at baseline and before each dose. 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 IMFINZI and IMJUDO depending on severity. See USPI Dosing and Administration for specific details. In general, if IMFINZI and IMJUDO requires interruption or discontinuation, administer systemic corticosteroid therapy (1 mg 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 corticosteroid therapy.
Immune-Mediated Pneumonitis
IMFINZI and IMJUDO can cause immune-mediated pneumonitis, which may be fatal. The incidence of pneumonitis is higher in patients who have received prior thoracic radiation.
Immune-Mediated Colitis
IMFINZI with IMJUDO and platinum-based chemotherapy can cause immune-mediated colitis, which may be fatal. IMFINZI and IMJUDO can cause immune-mediated colitis that is frequently associated with diarrhea. Cytomegalovirus (CMV) infection/reactivation has been reported in patients with corticosteroid-refractory immune-mediated colitis. In cases of corticosteroid-refractory colitis, consider repeating infectious workup to exclude alternative etiologies.
Immune-Mediated Hepatitis
IMFINZI and IMJUDO can cause immune-mediated hepatitis, which may be fatal.
Immune-Mediated Endocrinopathies
Immune-Mediated Nephritis with Renal Dysfunction
IMFINZI and IMJUDO can cause immune-mediated nephritis.
Immune-Mediated Dermatology Reactions
IMFINZI and IMJUDO can cause immune-mediated rash or dermatitis. Exfoliative dermatitis, including Stevens-Johnson Syndrome (SJS), drug rash with eosinophilia and systemic symptoms (DRESS), and toxic epidermal necrolysis (TEN), has occurred with PD-1/L-1 and CTLA-4 blocking antibodies. Topical emollients and/or topical corticosteroids may be adequate to treat mild to moderate non-exfoliative rashes.
Immune-Mediated Pancreatitis
IMFINZI in combination with IMJUDO can cause immune-mediated pancreatitis. Immune-mediated pancreatitis occurred in 2.3% (9/388) of patients receiving IMFINZI and IMJUDO, including Grade 4 (0.3%) and Grade 3 (1.5%) adverse reactions.
Other Immune-Mediated Adverse Reactions
The following clinically significant, immune-mediated adverse reactions occurred at an incidence of less than 1% each in patients who received IMFINZI and IMJUDO or were reported with the use of other immune-checkpoint inhibitors.
Infusion-Related Reactions
IMFINZI and IMJUDO can cause severe or life-threatening infusion-related reactions. Monitor for signs and symptoms of infusion-related reactions. Interrupt, slow the rate of, or permanently discontinue IMFINZI and IMJUDO based on the severity. See USPI Dosing and Administration for specific details. For Grade 1 or 2 infusion-related reactions, consider using pre-medications with subsequent doses.
Complications of Allogeneic HSCT after IMFINZI
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/L-1 blocking antibody. Transplant-related complications include hyperacute graft-versus-host disease (GVHD), acute GVHD, chronic GVHD, hepatic veno-occlusive disease (VOD) after reduced intensity conditioning, and steroid-requiring febrile syndrome (without an identified infectious cause). These complications may occur despite intervening therapy between PD-1/L-1 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/L-1 blocking antibody prior to or after an allogeneic HSCT.
Embryo-Fetal Toxicity
Based on their mechanism of action and data from animal studies, IMFINZI and IMJUDO can cause fetal harm when administered to a pregnant woman. Advise pregnant women of the potential risk to a fetus. In females of reproductive potential, verify pregnancy status prior to initiating IMFINZI and IMJUDO and advise them to use effective contraception during treatment with IMFINZI and IMJUDO and for 3 months after the last dose of IMFINZI and IMJUDO.
Lactation
There is no information regarding the presence of IMFINZI and IMJUDO in human milk; however, because of the potential for serious adverse reactions in breastfed infants from IMFINZI and IMJUDO, advise women not to breastfeed during treatment and for 3 months after the last dose.

Notes
Bladder cancer
Bladder cancer is the 8th most common cancer in the world, with more than 635,000 cases diagnosed each year. 7 The most common type is urothelial carcinoma, which begins in the urothelial cells of the urinary tract. 8
In 2026, around 15,000 patients will be treated for MIBC in the United States. 9 In 2025, the NIAGARA Phase III trial established a new standard of care by adding perioperative IMFINZI to neoadjuvant cisplatin-based chemotherapy and radical cystectomy. 10 However, up to half of patients are not eligible to receive cisplatin, and approximately 50% of MIBC patients who undergo bladder removal surgery experience disease recurrence. 4,6 New treatment options that prevent both progression before surgery and recurrence after surgery are critically needed in this curative-intent setting.
VOLGA
VOLGA is a Phase III, randomized, open-label, multi-center global trial evaluating perioperative IMFINZI with or without IMJUDO in combination with neoadjuvant EV as treatment for patients with MIBC undergoing radical cystectomy who are not eligible for or have declined cisplatin compared to radical cystectomy with or without approved adjuvant therapy. In the trial, 695 patients were randomized 1:1:1 to Arm 1 (three cycles of IMFINZI and EV, plus two cycles of IMJUDO prior to surgery, followed by nine cycles of IMFINZI plus one cycle of IMJUDO as adjuvant therapy), Arm 2 (three cycles of IMFINZI and EV prior to surgery, followed by nine cycles of IMFINZI adjuvant monotherapy) and Arm 3, the comparator arm.
The trial was conducted in 182 centers across 25 countries in Europe, North America, South America and Asia. Its dual primary endpoints are EFS, defined as the time from randomization to first recurrence post-radical cystectomy, first progression in patients who did not undergo radical cystectomy, failure to undergo radical cystectomy in patients with residual disease or death due to any cause, for both experimental arms versus the comparator arm. Secondary endpoints include OS (Arm 1 vs. Arm 3 and Arm 2 vs. Arm 3), pathologic complete response, disease-free survival and pathologic downstaging across both experimental arms.
IMFINZI ® (durvalumab)
IMFINZI ® (durvalumab) is a human monoclonal antibody that binds to the PD-L1 protein and blocks the interaction of PD-L1 with the PD-1 and CD80 proteins, countering the tumor's immune-evading tactics and releasing the inhibition of immune responses.
In addition to its bladder cancer indications, IMFINZI is the global standard of care based on OS in the curative-intent setting of unresectable, Stage III non-small cell lung cancer (NSCLC) in patients whose disease has not progressed after chemoradiotherapy (CRT). Additionally, IMFINZI is approved as a perioperative treatment in combination with neoadjuvant chemotherapy in resectable NSCLC, and in combination with a short course of IMJUDO ® (tremelimumab-actl) and chemotherapy for the treatment of metastatic NSCLC. IMFINZI is also approved for limited-stage small cell lung cancer (SCLC) in patients whose disease has not progressed following concurrent platinum-based CRT; and in combination with chemotherapy (etoposide and either carboplatin or cisplatin) for the treatment of extensive-stage SCLC.
Imfinzi is also approved in combination with chemotherapy in locally advanced or metastatic biliary tract cancer and in combination with Imjudo in unresectable hepatocellular carcinoma (HCC). It is also approved as a monotherapy in unresectable HCC in Japan, China and the EU, and in resectable, early-stage and locally advanced gastric and gastroesophageal junction cancers in the US, EU and Japan. Additionally, in April 2026, Imfinzi in combination with Imjudo, lenvatinib and transarterial chemoembolization (TACE) demonstrated a statistically significant and clinically meaningful improvement in the primary endpoint of PFS versus TACE alone for patients with unresectable HCC eligible for embolization in the EMERALD-3 Phase III trial.
IMFINZI in combination with chemotherapy followed by IMFINZI monotherapy is approved as a 1st-line treatment for primary advanced or recurrent endometrial cancer (mismatch repair deficient disease only in US, EU and China). IMFINZI in combination with chemotherapy followed by olaparib and IMFINZI is approved for patients with mismatch repair proficient advanced or recurrent endometrial cancer in EU and Japan.
Since the first approval in May 2017, more than 470,000 patients have been treated with IMFINZI. As part of a broad development program, IMFINZI is being tested as a single treatment and in combinations with other anti-cancer treatments for patients with NSCLC, bladder cancer, breast cancer, ovarian cancer and several gastrointestinal cancers.
