Under the Prescription Drug User Fee Act (PDUFA), the FDA has set a target action date of April 7, 2026.

The sBLA submission was based on results from the pivotal Phase 3 EV-303 clinical trial (also known as KEYNOTE-905) evaluating PADCEV, a Nectin-4 directed antibody-drug conjugate, in combination with KEYTRUDA, a PD-1 inhibitor, as neoadjuvant and adjuvant treatment versus surgery alone, the current standard of care. Detailed results from EV-303, which showed the combination reduced the risk of recurrence, progression or death by 60% and the risk of death by 50% compared to surgery alone, were presented at the 2025 European Society of Medical Oncology (ESMO) (Free ESMO Whitepaper) Congress. The safety results in EV-303 were consistent with those previously reported for this combination, and no new safety signals were identified.

About the EV-303/KEYNOTE-905 Trial
The EV-303 trial (also known as KEYNOTE-905) is an ongoing, open-label, randomized, three-arm, controlled, Phase 3 study evaluating neoadjuvant and adjuvant PADCEV in combination with KEYTRUDA or neoadjuvant and adjuvant KEYTRUDA versus surgery alone in patients with MIBC who are either not eligible for or declined cisplatin-based chemotherapy. Patients were randomized to receive either neoadjuvant and adjuvant KEYTRUDA (arm A), surgery alone (arm B) or neoadjuvant and adjuvant PADCEV in combination with KEYTRUDA (arm C).1

The primary endpoint of this trial is event-free survival (EFS) between arm C and arm B, defined as the time from randomization to the first occurrence of any of the following events: progression of disease that precludes radical cystectomy (RC) surgery or failure to undergo RC surgery in participants with residual disease, gross residual disease left behind at the time of surgery, local or distant recurrence as assessed by imaging and/or biopsy or death due to any cause. Key secondary endpoints include overall survival (OS) and pathologic complete response (pCR) rate between arm C and arm B, as well as EFS, OS and pCR rate between arm A and arm B.1

About Muscle-Invasive Bladder Cancer
Bladder cancer is the ninth most common cancer worldwide, diagnosed in more than 614,000 people each year globally, including an estimated 85,000 people in the U.S.2,3 MIBC represents approximately 30% of all bladder cancer cases.4 The standard treatment for patients with MIBC is neoadjuvant cisplatin-based chemotherapy followed by surgery, which has been shown to prolong survival.5 However, up to half of patients with MIBC are not eligible to receive cisplatin and face limited treatment options, typically undergoing surgery without any systemic treatment.6

About PADCEV (enfortumab vedotin)
PADCEV (enfortumab vedotin) is a first-in-class antibody-drug conjugate (ADC) that is directed against Nectin-4, a protein located on the surface of cells and highly expressed in bladder cancer.7 Nonclinical data suggest the anticancer activity of PADCEV is due to its binding to Nectin-4-expressing cells, followed by the internalization and release of the anti-tumor agent monomethyl auristatin E (MMAE) into the cell, which result in the cell not reproducing (cell cycle arrest) and in programmed cell death (apoptosis).8

PADCEV plus KEYTRUDA is approved for the treatment of adult patients with locally advanced or metastatic urothelial cancer (la/mUC) regardless of cisplatin eligibility in the United States, the European Union, Japan and a number of other countries around the world. PADCEV is also approved as a single agent for the treatment of adult patients with la/mUC who have previously received a PD-1/PD-L1 inhibitor and platinum-containing chemotherapy or are ineligible for cisplatin-containing chemotherapy and have previously received one or more prior lines of therapy.8

PADCEV Important Safety Information 

Warnings and Precautions 

Skin reactions Severe cutaneous adverse reactions, including fatal cases of SJS or TEN occurred in patients treated with PADCEV. SJS and TEN occurred predominantly during the first cycle of treatment but may occur later. Skin reactions occurred in 70% (all grades) of the 564 patients treated with PADCEV in combination with pembrolizumab in clinical trials. When PADCEV was given in combination with pembrolizumab, the incidence of skin reactions, including severe events, occurred at a higher rate compared to PADCEV as a single agent. The majority of the skin reactions that occurred with combination therapy included maculo-papular rash, macular rash and papular rash. Grade 3-4 skin reactions occurred in 17% of patients (Grade 3: 16%, Grade 4: 1%), including maculo-papular rash, bullous dermatitis, dermatitis, exfoliative dermatitis, pemphigoid, rash, erythematous rash, macular rash, and papular rash. A fatal reaction of bullous dermatitis occurred in one patient (0.2%). The median time to onset of severe skin reactions was 1.7 months (range: 0.1 to 17.2 months). Skin reactions led to discontinuation of PADCEV in 6% of patients. 

Skin reactions occurred in 58% (all grades) of the 720 patients treated with PADCEV as a single agent in clinical trials. Twenty-three percent (23%) of patients had maculo-papular rash and 34% had pruritus. Grade 3-4 skin reactions occurred in 14% of patients, including maculo-papular rash, erythematous rash, rash or drug eruption, symmetrical drug-related intertriginous and flexural exanthema (SDRIFE), bullous dermatitis, exfoliative dermatitis, and palmar-plantar erythrodysesthesia. The median time to onset of severe skin reactions was 0.6 months (range: 0.1 to 8 months). Among patients experiencing a skin reaction leading to dose interruption who then restarted PADCEV (n=75), 24% of patients restarting at the same dose and 24% of patients restarting at a reduced dose experienced recurrent severe skin reactions. Skin reactions led to discontinuation of PADCEV in 3.1% of patients. 

Monitor patients closely throughout treatment for skin reactions. Consider topical corticosteroids and antihistamines, as clinically indicated. For persistent or recurrent Grade 2 skin reactions, consider withholding PADCEV until Grade ≤1. Withhold PADCEV and refer for specialized care for suspected SJS, TEN or for Grade 3 skin reactions. Permanently discontinue PADCEV in patients with confirmed SJS or TEN; or Grade 4 or recurrent Grade 3 skin reactions. 

Hyperglycemia and diabetic ketoacidosis (DKA), including fatal events, occurred in patients with and without pre-existing diabetes mellitus, treated with PADCEV. Patients with baseline hemoglobin A1C ≥8% were excluded from clinical trials. In clinical trials of PADCEV as a single agent, 17% of the 720 patients treated with PADCEV developed hyperglycemia of any grade; 7% of patients developed Grade 3-4 hyperglycemia (Grade 3: 6.5%, Grade 4: 0.6%). Fatal events of hyperglycemia and DKA occurred in one patient each (0.1%). The incidence of Grade 3-4 hyperglycemia increased consistently in patients with higher body mass index and in patients with higher baseline A1C. The median time to onset of hyperglycemia was 0.5 months (range: 0 to 20 months). Hyperglycemia led to discontinuation of PADCEV in 0.7% of patients. Five percent (5%) of patients required initiation of insulin therapy for treatment of hyperglycemia. Of the patients who initiated insulin therapy for treatment of hyperglycemia, 66% (23/35) discontinued insulin at the time of last evaluation. Closely monitor blood glucose levels in patients with, or at risk for, diabetes mellitus or hyperglycemia. If blood glucose is elevated (>250 mg/dL), withhold PADCEV. 

Pneumonitis/Interstitial Lung Disease (ILD) Severe, life-threatening or fatal pneumonitis/ILD occurred in patients treated with PADCEV. When PADCEV was given in combination with pembrolizumab, 10% of the 564 patients treated with combination therapy had pneumonitis/ILD of any grade and 4% had Grade 3-4. A fatal event of pneumonitis/ILD occurred in two patients (0.4%). The incidence of pneumonitis/ILD, including severe events, occurred at a higher rate when PADCEV was given in combination with pembrolizumab compared to PADCEV as a single agent. The median time to onset of any grade pneumonitis/ILD was 4 months (range: 0.3 to 26 months). 

In clinical trials of PADCEV as a single agent, 3% of the 720 patients treated with PADCEV had pneumonitis/ILD of any grade and 0.8% had Grade 3-4. The median time to onset of any grade pneumonitis/ILD was 2.9 months (range: 0.6 to 6 months). 

Monitor patients for signs and symptoms indicative of pneumonitis/ILD such as hypoxia, cough, dyspnea or interstitial infiltrates on radiologic exams. Evaluate and exclude infectious, neoplastic and other causes for such signs and symptoms through appropriate investigations. Withhold PADCEV for patients who develop Grade 2 pneumonitis/ILD and consider dose reduction. Permanently discontinue PADCEV in all patients with Grade 3 or 4 pneumonitis/ILD. 

Peripheral neuropathy (PN) When PADCEV was given in combination with pembrolizumab, 67% of the 564 patients treated with combination therapy had PN of any grade, 36% had Grade 2 neuropathy, and 7% had Grade 3 neuropathy. The incidence of PN occurred at a higher rate when PADCEV was given in combination with pembrolizumab compared to PADCEV as a single agent. The median time to onset of Grade ≥2 PN was 6 months (range: 0.3 to 25 months). 

PN occurred in 53% of the 720 patients treated with PADCEV as a single agent in clinical trials including 38% with sensory neuropathy, 8% with muscular weakness and 7% with motor neuropathy. Thirty percent of patients experienced Grade 2 reactions and 5% experienced Grade 3-4 reactions. PN occurred in patients treated with PADCEV with or without preexisting PN. The median time to onset of Grade ≥2 PN was 4.9 months (range: 0.1 to 20 months). Neuropathy led to treatment discontinuation in 6% of patients. 

Monitor patients for symptoms of new or worsening PN and consider dose interruption or dose reduction of PADCEV when PN occurs. Permanently discontinue PADCEV in patients who develop Grade ≥3 PN. 

Ocular disorders were reported in 40% of the 384 patients treated with PADCEV as a single agent in clinical trials in which ophthalmologic exams were scheduled. The majority of these events involved the cornea and included events associated with dry eye such as keratitis, blurred vision, increased lacrimation, conjunctivitis, limbal stem cell deficiency, and keratopathy. Dry eye symptoms occurred in 30% of patients, and blurred vision occurred in 10% of patients, during treatment with PADCEV. The median time to onset to symptomatic ocular disorder was 1.7 months (range: 0 to 30.6 months). Monitor patients for ocular disorders. Consider artificial tears for prophylaxis of dry eyes and ophthalmologic evaluation if ocular symptoms occur or do not resolve. Consider treatment with ophthalmic topical steroids, if indicated after an ophthalmic exam. Consider dose interruption or dose reduction of PADCEV for symptomatic ocular disorders. 

Infusion site extravasation Skin and soft tissue reactions secondary to extravasation have been observed after administration of PADCEV. Of the 720 patients treated with PADCEV as a single agent in clinical trials, 1% of patients experienced skin and soft tissue reactions, including 0.3% who experienced Grade 3-4 reactions. Reactions may be delayed. Erythema, swelling, increased temperature, and pain worsened until 2-7 days after extravasation and resolved within 1-4 weeks of peak. Two patients (0.3%) developed extravasation reactions with secondary cellulitis, bullae, or exfoliation. Ensure adequate venous access prior to starting PADCEV and monitor for possible extravasation during administration. If extravasation occurs, stop the infusion and monitor for adverse reactions. 

Embryo-fetal toxicity PADCEV can cause fetal harm when administered to a pregnant woman. Advise patients of the potential risk to the fetus. Advise female patients of reproductive potential to use effective contraception during PADCEV treatment and for 2 months after the last dose. Advise male patients with female partners of reproductive potential to use effective contraception during treatment with PADCEV and for 4 months after the last dose.

IBI363 (PD-1/IL-2α-bias): Global Joint Development and Commercialization Collaboration

IBI363, developed by Innovent Biologics, is a potentially first-in-class PD-1/IL-2α-biased bispecific antibody fusion protein that simultaneously blocks the PD-1/PD-L1 pathway and activates the IL-2 pathway. Innovent has shown that IBI363, with an IL-2 receptor alpha focused approach, selectively expands tumor-specific CD8+ T cells that increase tumor cell killing efficiency without activating or expanding the toxicity related to peripheral T cells, which results in a better safety profile than what is seen with traditional IL-2s. Phase 1b/2 results presented at ASCO (Free ASCO Whitepaper) 2025 have demonstrated outstanding tumor responses and preliminary survival benefits of IBI363 across immunotherapy-resistant lung cancer, "cold tumors" such as acral and mucosal melanoma, and MSS colorectal cancer. IBI363 is now in registrational clinical development, including a global Phase 3 study in second line sqNSCLC that is expected to begin in the coming months; the China NMPA has granted Breakthrough Designation (BTD) and U.S. FDA has granted Fast Track Designation (FTD) for this indication.

According to the agreement, Innovent and Takeda will co-develop IBI363 globally, sharing development costs 40/60 (Innovent/Takeda). In the U.S., Innovent and Takeda will co-commercialize IBI363, sharing the U.S. profit or loss 40/60. Takeda will lead the co-development and co-commercialization efforts under joint governance and aligned development plan. In addition, Innovent will grant Takeda commercialization rights outside Greater China and the U.S. Takeda will have global manufacturing rights to supply IBI363 outside of Greater China, with such rights being co-exclusive with Innovent for commercial supply in the U.S. Takeda will pay Innovent potential development and sales milestones outside Greater China, and tiered royalties up to high-teens on net sales outside Greater China and the U.S.

This collaboration aims to explore and maximize IBI363’s potential as a new IO backbone therapy through aligned co-development plans. Building on its already robust clinical data of over 1,200 treated patients, IBI363 will be initially developed globally in non-small cell lung cancer ("NSCLC") and colorectal cancer ("CRC"), including in the first-line settings. Additionally, Takeda and Innovent plan to expand IBI363’s clinical development to additional indications.

IBI343 (CLDN18.2 ADC): Global License for Development and Commercialization

IBI343, developed by Innovent Biologics, is an innovative TOPO1 inhibitor ADC targeting CLDN18.2. Clinical data show a favorable safety profile and encouraging efficacy signals. It is currently being evaluated in a Phase 3 clinical trial in gastric/gastroesophageal cancers (G-HOPE-001) in China and Japan, and was granted Breakthrough Designation in China. IBI343 also completed a global Phase 1/2 trial in previously treated pancreatic ductal adenocarcinoma (PDAC) and has received Breakthrough Designation in China for this indication. It has also received Fast Track Designation from the U.S. FDA for the treatment of advanced unresectable or metastatic pancreatic ductal adenocarcinoma (PDAC) that has relapsed and/or is refractory to one prior line of therapy.

Innovent will grant Takeda exclusive global rights to develop, manufacture and commercialize IBI343 outside of Greater China. Takeda plans to advance the development of IBI343 and expand into first-line gastric and pancreatic cancer settings.

(Press release, Innovent Biologics, OCT 21, 2025, View Source [SID1234656878])

Takeda will make potential milestone payments, and tiered royalties on net sales up to high-teens for the license of IBI343.

IBI3001 (EGFR/B7H3 ADC): Option to Global License for Development and Commercialization

IBI3001, currently in a Phase 1 clinical trial, is a first-in-class bispecific ADC targeting B7-H3 and EGFR. It combines multiple anti-tumor mechanisms, including enhanced EGFR blockade, receptor-mediated internalization, and strong ADC-mediated cytotoxicity, with a high safety margin demonstrated in preclinical models.

Innovent will grant Takeda an exclusive option to license global development, manufacturing, and commercialization rights for IBI3001 outside of Greater China. If exercised, Takeda will pay Innovent an exercise fee, potential milestone payments, and tiered royalties on net sales up to mid-teens.

Financial Highlights: Total Deal Value up to $11.4Billion

Takeda will pay Innovent an upfront payment of US$1.2 billion, including a US$100 million equity investment in Innovent through new share issuance, at HK$112.56 per share, a 20% premium to the Innovent 30-trading-day weighted average share price.

Furthermore, Innovent is eligible for development and sales milestone payments for IBI363, IBI343, and IBI3001 (if option exercised) totaling up to approximately $10.2 billion, for a total deal value of up to $11.4 billion. Innovent will also receive potential royalty payments for each molecule outside Greater China, except with respect to IBI363 in the U.S., where the parties will share profits or losses.

Innovent will host conference calls and webcasts at 9:00 a.m. HKT (Chinese session) and 9:00 p.m. HKT (English session) on Wednesday, October 22, 2025.Details of the conference call dial-in and the webcast link will be provided on the company website at View Source A replay will also be available on the website shortly after the event.

Morgan Stanley Asia Limited serves as the exclusive financial advisor to Innovent Biologics in relation to this transaction.

Xspray Pharma AB (publ) (Nasdaq Stockholm: XSPRAY) announces that the U.S. Food and Drug Administration (FDA) has accepted the company’s New Drug Application (NDA) for XS003 (nilotinib) for review under the 505(b)(2) regulatory pathway. The FDA has set a PDUFA date to June 18, 2026, which is the date by when the agency is expected to announce a decision on the application.

On October 21, 2025 Xspray pharma reported XS003 is an improved formulation of nilotinib (Tasigna) for the treatment of chronic myeloid leukemia (CML), developed using Xspray’s proprietary HyNap technology. Data demonstrate bioequivalence to the reference product at less than half the dose, as well as a significantly reduced food effect (29% compared to 82% for Tasigna). The food effect associated with the reference product complicates patient adherence and is related to the requirement that the patient must be in a fasting state, which is included in its so-called "boxed warning" regarding QTc prolongation and the risk of sudden death. The significantly reduced food effect with XS003 means it is expected that it may be taken with or without food and thereby avoid warning text regarding food interaction. Any final labeling and related warnings will be determined by the FDA during the review process.

"The FDA’s decision to accept our NDA for review marks an important milestone," says Per Andersson, CEO of Xspray Pharma. "With two product candidates under FDA review, we are demonstrating that the HyNap platform has broad applicability and the potential to deliver more improved TKIs to the market."

Together with the company’s first product candidate Dasynoc, XS003 addresses a U.S. market of approximately USD 2.7 billion. The FDA’s notification confirms that the application is complete and that a full review is now underway. XS003 is manufactured at the same external facility as Dasynoc.

"Since the FDA now has a solid understanding of our manufacturing process, I am confident that the upcoming Pre-Approval Inspection will be completed without observations. It is essentially the same process that has previously been inspected. Furthermore, we are working closely with the manufacturer to ensure that all planned improvements to the other parts of the facility that previously received observations are completed well ahead of the PDUFA date," comments CEO Per Andersson.

Summary of License and Collaboration Agreement

Novartis received an exclusive worldwide license to research, develop, manufacture, and commercialize ARO-SNCA, a preclinical stage program that utilizes Arrowhead’s Targeted RNAi Molecule (TRiMTM) platform for subcutaneous administration and delivery to the CNS designed to target the gene that encodes the alpha-synuclein protein as a potential treatment for patients with Parkinson’s Disease, and other synucleinopathies. Novartis may also select additional collaboration targets outside of Arrowhead’s current pipeline to be developed using the TRiMTM platform.

For all licensed programs under the agreement, Arrowhead will conduct and complete preclinical research activities necessary to enable a clinical trial application (CTA) filing. Novartis will then assume sole control over development, manufacturing, medical affairs, and commercialization activities.

Summary Financial Terms

Arrowhead will receive a $200 million upfront payment from Novartis and is also eligible to receive development, regulatory, and sales milestone payments of up to $2 billion. Arrowhead is further eligible to receive tiered royalties on commercial sales up to the low double digits.

About XmAb819

XmAb819 is a first-in-class, tumor-targeted, T-cell engaging XmAb 2+1 bispecific antibody in development for patients with clear cell renal cell carcinoma (ccRCC). XmAb819 engages the immune system and activates T cells for highly potent and targeted lysis of tumor cells expressing ENPP3, an antigen highly expressed on kidney cancers. ENPP3 is a differentially expressed target, with high level expression in renal cell carcinoma (RCC) and low-level expression on normal tissues. With two tumor-antigen binding domains and one T-cell binding domain, Xencor’s XmAb 2+1 format enables antibodies to bind more avidly and selectively kill tumor cells with higher antigen density, potentially sparing normal cells. Xencor is conducting a Phase 1 study to evaluate XmAb819 in patients with advanced ccRCC.
