On November 6, 2025 UroGen Pharma Ltd. (Nasdaq: URGN), a biotech company dedicated to developing and commercializing innovative solutions that treat urothelial and specialty cancers, reported robust preliminary results from its ongoing Phase 3 UTOPIA trial, demonstrating a 77.8% three-month complete response (CR) rate (95% CI, 68.3%, 85.5%) with UGN-103 (mitomycin) for intravesical solution in patients with recurrent low-grade intermediate-risk non-muscle invasive bladder cancer (LG-IR-NMIBC). This result is consistent with the 79.6% three-month CR rate (95% CI, 73.9%, 84.5%) observed following treatment with ZUSDURI in the pivotal ENVISION trial. In addition, the U.S. Food and Drug Administration (FDA) agreed that CR and durability results from the UTOPIA trial can support the submission of a New Drug Application (NDA) for UGN-103 for recurrent LG-IR-NMIBC.

"The robust 77.8% three-month CR rate observed in the UTOPIA trial is highly encouraging and reinforces the potential of UGN-103 to deliver meaningful benefits to patients," said Liz Barrett, President and Chief Executive Officer of UroGen. "In addition, the FDA’s agreement that the UTOPIA trial can support the submission of an NDA for UGN-103 represents a significant regulatory milestone and a strong validation of our clinical strategy. Together, these achievements give us significant momentum and a clear path toward potential approval, positioning UGN-103 as a key growth driver and marking an important advancement in expanding our leadership in uro-oncology. We look forward to working closely with the FDA as we complete the UTOPIA trial and prepare for an NDA submission in 2026."

UGN-103 is designed to offer key improvements over ZUSDURI (mitomycin) for intravesical solution, the first and only FDA-approved treatment for adults with recurrent LG-IR-NMIBC. These include a shorter manufacturing process and a simplified reconstitution procedure, while maintaining UroGen’s established approach that enables prolonged drug exposure within the bladder. UroGen has two U.S. patents with claims relating to the combination of the Company’s RTGel technology combined with medac’s licensed proprietary lyophilized mitomycin formulation. These patents cover UGN-103 as well as the use of UGN-103 for the treatment of LG-IR-NMIBC and expire in December 2041.

About UTOPIA

The UTOPIA trial is a single-arm, multicenter study evaluating the efficacy and safety of UGN-103 in 99 patients across global sites. Enrolled patients received 75 mg of UGN-103 via intravesical instillation once weekly for six weeks. The primary endpoint is complete response rate at three months, with responders entering a follow-up phase of up to 12 months to assess durability of response. For more information on the UTOPIA study, please visit View Source

About UGN-103
In January 2024, UroGen entered into a licensing and supply agreement with medac to develop UGN-103 for LG-IR-NMIBC. UGN-103 is an innovative mitomycin formulation that aims to streamline manufacturing and reconstitution processes while providing intellectual property coverage until December 2041. It utilizes UroGen’s RTGel technology for prolonged mitomycin exposure.

About ZUSDURI

ZUSDURI (mitomycin) for intravesical solution is an innovative drug formulation of mitomycin approved for the treatment of adults with recurrent LG-IR-NMIBC. Utilizing UroGen’s proprietary RTGel technology (a sustained release, hydrogel-based formulation), ZUSDURI is delivered directly into the bladder by a trained healthcare professional using a urinary catheter in an outpatient setting, thereby enabling the treatment of tumors by non-surgical means.

About Non-Muscle Invasive Bladder Cancer (NMIBC)
LG-IR-NMIBC affects around 82,000 people in the U.S. every year and of those, an estimated 59,000 are recurrent. Bladder cancer primarily affects older populations with increased risk of comorbidities, with the median age of diagnosis being 73 years. Guideline recommendations for the management of NMIBC include transurethral resection of bladder tumor (TURBT) as the standard of care. Up to 70 percent of NMIBC patients experience at least one recurrence, and LG-IR-NMIBC patients are even more likely to recur and face repeated TURBT procedures.

On November 6, 2025 Guardant Health, Inc. (Nasdaq: GH), a leading precision oncology company, reported new data demonstrating that its Guardant Reveal blood test helps clinicians to assess the effectiveness of chemotherapy in patients with advanced solid tumors months earlier than conventional methods. This is the first robust clinical validation study of pan-cancer chemotherapy monitoring, published in the Journal of Liquid Biopsy. The study used a tissue-free, methylation-based ctDNA tumor fraction signal to track changes in cancer over time and provides real-world evidence that changes detected in a blood-based tumor signal correlate strongly with patient outcomes, offering oncologists a timely and non-invasive tool for monitoring cancer therapy.

The study showed that any decrease in tumor fraction signal after chemotherapy initiation was associated with both longer treatment duration and increased survival rates. Notably, patients who experienced a greater than 98% reduction in the tumor signal saw the most significant benefits. Conversely, a rise in the tumor signal identified disease progression up to 18 months earlier with a median lead time of 2.3 months – much earlier than standard clinical measures could detect.

"This study demonstrates the potential of a blood test to give oncologists an earlier and accurate look at whether chemotherapy is helping," said Dr. Craig Eagle, Guardant Health Chief Medical Officer. "Guardant Reveal’s ability to detect molecular changes weeks or months before they show up on scans give doctors more time to adjust care and potentially spare patients from the toxicity of ineffective treatment."

The majority of patients with metastatic solid tumors receive chemotherapy at some point during their treatment. Guardant Reveal interrogates nearly 30,000 methylated regions across the genome resulting in unparalleled precision for tracking and monitoring tumor burden in patients. Because the methylation-based tumor fraction test doesn’t require tumor tissue, Guardant Reveal can be used more broadly to monitor treatment response across multiple cancer types.

"In Q3 2025, we gained significant momentum on our strategy to develop innovative oncology therapies that substantially increase patient survival," said Denny Lanfear, Coherus Chairman and Chief Executive Officer. "The vast majority of our study sites are enrolling, driving towards multiple data readouts in 2026 across a number of tumor types. We have now expanded our CHS-114 CCR8 Treg depleter clinical program to include colorectal cancer, an area of growing unmet need, impacting even younger patients."

"The importance of CCR8 as a cancer target is highlighted by the 2025 Nobel Prize in Physiology or Medicine, which recognized the pivotal role of Treg cells in peripheral immune tolerance and their pathological role in autoimmunity and cancer," said Theresa LaVallee, PhD, Coherus Chief Scientific and Development Officer. Coherus Oncology was recently honored to present our clinical data on CHS-114 showing the cytolytic antibody’s potency and selectively, with robust tumoral Treg depletion, immune activation and a good safety profile at a SITC (Free SITC Whitepaper) presentation focused on a deep dive into development of antibodies targeting CCR8 Tregs, reflecting our scientific leadership in this rapidly evolving field."

"Our clinical programs target tumor types where there is a clear biological rationale and a significant unmet medical need with available therapies," said Rosh Dias, MD, Chief Medical Officer. "We have previously shown encouraging data for both casdozokitug and CHS-114, and we expect maturing datasets from our ongoing studies throughout 2026."

RECENT BUSINESS HIGHLIGHTS

LOQTORZI (toripalimab-tpzi) Commercial Updates

LOQTORZI remains the only FDA-approved and available treatment in the U.S. for recurrent, locally advanced or metastatic nasopharyngeal carcinoma (NPC), in all patient subsets and across all lines of therapy.
LOQTORZI net revenue for Q3 2025 was $11.2 million, a 12% increase over $10.0 million in Q2 2025 and a 92% increase over LOQTORZI net revenue of $5.8 million in Q3 2024. Growth in Q3 2025 was driven largely by higher patient demand from both increasing new account starts as well as repeat use in existing accounts. Average duration of treatment among existing patients also continues to grow.
Increasing awareness of the revised National Comprehensive Cancer Network (NCCN) guidelines granting LOQTORZI preferred status within the NPC indication continues to drive strong demand growth among head & neck cancer specialists. The Company’s focus remains on deepening adoption within general oncologists in the community setting by driving education on clinical data and updated NCCN guidelines. While half of all NPC patients in the U.S. are managed in this setting, market penetration will continue at a steady and gradual pace due to the rarity of patients seen by these oncologists.

ADVANCEMENT OF INNOVATIVE, NEXT-GENERATION ONCOLOGY PIPELINE

LOQTORZI is a next-generation PD-1 marketed in the U.S. in two indications.

Coherus plans to maximize the value of this medicine by combining LOQTORZI with internal pipeline candidates, CHS-114 and casdozokitug, for additional solid tumor indications and entering into capital-efficient external partnerships for label expansions.
In October 2025, the Cancer Research Institute announced the first patient enrolled in the third cohort of the ongoing Immunotherapy Platform Study in Platinum-Resistant High-Grade Serous Ovarian Cancer (IPROC) (NCT04918186). The third cohort of the Phase 2 trial is evaluating LOQTORZI in combination with ENB Therapeutics’ ENB-003 for the treatment of ovarian cancer.

CHS-114 is a highly selective cytolytic CCR8 antibody that specifically binds and preferentially depletes CCR8+ tumor regulatory T cells (Tregs) with no off-target binding.

Updated biomarker data from the Phase 1b study dose expansion study in 2L+ head and neck squamous cell carcinoma (HNSCC) will be presented on Saturday, November 8, 2025 at the 40th Annual Meeting of the Society for Immunotherapy of Cancer (SITC) (Free SITC Whitepaper).
Phase 1b CHS-114/toripalimab combination dose optimization studies in 2L HNSCC and 2L gastric cancers are underway, with initial data readouts for HNSCC expected in 1H 2026.
A Phase 1b study evaluating the CHS-114/toripalimab combination, with and without chemotherapy, in 1L and 2L esophageal squamous cell carcinoma (ESCC), respectively, is underway with a first data readout expected in mid-2026.
A Phase 1b/2a study evaluating CHS-114/toripalimab combination in 4L+ colorectal cancer is enrolling patients and initial data is expected in 2H 2026.

Casdozokitug is a first-in-class, clinical-stage IL-27 antagonist, with demonstrated monotherapy activity in treatment-refractory non-small cell lung cancer (NSCLC) and clear cell renal cell carcinoma (ccRCC) and combination activity in hepatocellular carcinoma (HCC).

Enrollment is ongoing in the Phase 2 randomized trial of casdozokitug/toripalimab/bevacizumab in 1L HCC, with the first data readout expected in mid-2026.
On November 2, 2025, new data was presented at the Cytokines 2025 annual meeting demonstrating casdozokitug promotes NK and T cell activity, and antitumor response in patients with advanced solid tumors. These biomarker data continue to support treatment with casdozokitug which leads to inhibition of IL-27 signaling and enhanced cytolytic immune activity (by NK and T cells). The new data reveal these biomarker changes following treatment of HCC patients with casdozokitug and standard of care are associated with clinical response (and thus, support an important contribution of casdozokitug).

THIRD QUARTER 2025 FINANCIAL RESULTS

Net revenue from continuing operations was $11.6 million and $6.1 million during the three months ended September 30, 2025 and 2024, respectively, and $29.4 million and $18.7 million during the nine months ended September 30, 2025 and 2024, respectively. LOQTORZI net product revenue increased $5.3 million and $16.9 million compared to the three and nine months ended September 30, 2024, respectively, driven primarily by volume growth of LOQTORZI, which launched in December 2023. The increase in the nine-month period was partially offset by a decrease in other revenue primarily driven by a $6.1 million upfront fee recognized in the prior year for the out-license of rights to commercialize toripalimab within Canada.

Cost of goods sold (COGS) from continuing operations was $3.7 million and $2.7 million during the three months ended September 30, 2025 and 2024, respectively, and $9.8 million and $6.0 million during the nine months ended September 30, 2025 and 2024, respectively. The increases were primarily due to volume growth of LOQTORZI.

Research and development (R&D) expenses from continuing operations were $27.3 million and $22.1 million for the three months ended September 30, 2025 and 2024, respectively, and $77.9 million and $71.1 million during the nine months ended September 30, 2025 and 2024, respectively. The increases were primarily due to increased costs for development of casdozokitug and CHS-114, partially offset by savings from reduced activities related to other programs, reduced headcount, and lower infrastructure costs.

Selling, general and administrative (SG&A) expenses from continuing operations were $24.9 million and $28.1 million during the three months ended September 30, 2025 and 2024, respectively, and $77.0 million and $95.9 million during the nine months ended September 30, 2025 and 2024, respectively. The decreases were driven primarily by lower headcount and decreased operating costs following Coherus’ recent divestitures, partially offset by a $1.6 million net impairment charge in the third quarter of 2025 for the write-off of an intangible asset and associated contingent value right ("CVR") liability related to GSK4381562, acquired in the Surface Oncology, Inc. acquisition. The decrease in the nine-month period was further due to a net $6.8 million charge in the first quarter of 2024 for the write-off of an intangible asset and associated CVR liability related to NZV930, which was also acquired in the Surface Oncology, Inc. acquisition.

Interest expense from continuing operations was $2.3 million and $2.8 million during the three months ended September 30, 2025 and 2024, respectively, and $6.8 million and $8.8 million during the nine months ended September 30, 2025 and 2024, respectively. The decrease in the nine-month period was primarily due to the prepayment of the remaining $75.0 million of the principal amount due under the 2027 Term Loans on May 8, 2024, partially offset by interest on the $38.7 million senior secured term loan facility and the LOQTORZI portion of the Revenue Participation Right Purchase and Sale Agreement, each commencing May 8, 2024.

Net loss from continuing operations for the third quarter of 2025 was $44.5 million, or $(0.38) per share on a diluted basis, compared to a net loss of $47.6 million, or $(0.41) per share on a diluted basis, for the same period in 2024. Net loss for the nine months ended September 30, 2025 was $136.8 million, or $(1.18) per share on a diluted basis, compared to net loss of $169.3 million, or $(1.48) per share on a diluted basis, for the same period in 2024.

Non-GAAP net loss from continuing operations for the third quarter of 2025 was $38.9 million, or $(0.33) per share on a diluted basis, compared to $40.0 million, or $(0.35) per share for the same period in 2024. Non-GAAP net loss for the nine months ended September 2025 was $118.8 million, or $(1.02) per share on a diluted basis, compared to a net loss of $127.1 million, or $(1.11) per share for the same period in 2024. See "Non-GAAP Financial Measures" below for a discussion on how Coherus calculates non-GAAP net loss from continuing operations and a reconciliation to the most directly comparable GAAP measures.

Cash, cash equivalents and marketable securities totaled $191.7 million as of September 30, 2025, compared to $126.0 million as of December 31, 2024. A majority of the $67.0 million in accrued rebates, fees and reserves reflected on the September 30, 2025 balance sheet were UDENYCA-related obligations that did not transfer in the divestiture and are expected to be settled in a front-weighted fashion over the remainder of the year and into 2026.

Recent Pipeline Highlights

Below are key product updates since our last earnings release:

Oncology Pipeline

•Zocilurtatug Pelitecan (zoci, DLL3 ADC) (formerly ZL-1310):

–In October 2025, Zai Lab initiated a global registrational study of zocilurtatug pelitecan monotherapy in second-line+ extensive-stage small cell lung cancer (ES-SCLC).

–In October 2025, Zai Lab presented updated Phase 1 results at the AACR (Free AACR Whitepaper)-NCI-EORTC International Conference, demonstrating a best overall response rate of 68% at the 1.6 mg/kg dose in second-line extensive-stage small cell lung cancer. The estimated median duration of response (DoR) of 6.1 months across all doses and all lines of therapy is highly encouraging for a monotherapy in this heavily pre-treated and difficult-to-treat patient population. Meaningful activity in patients with brain metastases was also observed, including an 80% response rate in patients with untreated brain metastases. The data also demonstrated a well-tolerated safety profile at 1.6 mg/kg, with Grade ≥ 3 treatment-related adverse events of 13%, no Grade ≥2 interstitial lung disease, and no drug discontinuations. Together, these results reinforce zoci’s best-in-class potential and support the initiation of the global registrational study.

•Tumor Treating Fields (TTFields): In August 2025, Zai Lab announced that the China National Medical Products Administration (NMPA) has granted Innovative Medical Device Designation for TTFields for patients with pancreatic cancer based on the positive results from the Phase 3 PANOVA-3 trial. We plan to submit for regulatory approval in China in the fourth quarter of 2025.

•Bemarituzumab (FGFR2b): In November 2025, Zai Lab partner Amgen announced FORTITUDE-102, a Phase 1b/3 study of bemarituzumab plus chemotherapy and nivolumab in patients with first-line gastric cancer, was stopped.

Immunology Pipeline

•ZL-1503 (IL-13/IL-31R): In November 2025, Zai Lab initiated a global Phase 1/1b study to evaluate safety, tolerability and pharmacokinetics of ZL-1503 in healthy volunteers and participants with moderate to severe atopic dermatitis.

•Efgartigimod (FcRn):

–Sjogren’s disease: In September 2025, Zai Lab joined the registrational UNITY study of efgartigimod subcutaneous given by prefilled syringe in Sjogren’s disease in Greater China (mainland China, Hong Kong, Macau and Taiwan, collectively).

–Seronegative gMG: In August 2025, Zai Lab partner argenx announced topline data from the pivotal ADAPT SERON study of VYVGART in patients with AChR-Ab seronegative gMG. The study met its primary endpoint (p-value=0.0068) and it is the first global phase 3 study to demonstrate clinically meaningful improvements in disease activity across all three subtypes – MuSK+, LRP4+, triple seronegative. Zai Lab participated in the global Phase 3 study in Greater China, enabling a potential China regulatory submission.

•Xanomeline-Trospium (or KarXT) (M1/M4-agonist): In September 2025, the "China Schizophrenia Prevention and Treatment Guidelines (2025 Edition)" were officially released, and KarXT was included for the first time, marking the first national-level guideline globally to include KarXT. The guidelines emphasize KarXT’s broad efficacy across all three symptom domains (positive, negative, and cognitive symptoms) and its unique safety profile, supporting long-term adherence and functional recovery. China’s NMPA accepted the New Drug Application (NDA) for the treatment of schizophrenia in January 2025.

•Povetacicept: In September 2025, the U.S. Food and Drug Administration (FDA) granted Breakthrough Therapy Designation (BTD) to povetacicept for the treatment of IgA nephropathy (IgAN). Subsequently, the FDA also granted a rolling review of the Biologics License Application (BLA) submission for povetacicept for this indication. Vertex has completed full enrollment of the Phase 3 study, including the interim analysis cohort for potential accelerated approval in the U.S. Zai Lab participated in the global Phase 3 RAINIER study in patients with IgAN in Greater China.

Third Quarter 2025 Financial Results

•Product revenue, net was $115.4 million in the third quarter of 2025, compared to $101.8 million for the same period in 2024, representing 13% y-o-y growth, 14% y-o-y growth at constant exchange rate (CER). This increase was primarily driven by increased sales for NUZYRA and XACDURO, partially offset by softer sales for ZEJULA:

–VYVGART and VYVGART Hytrulo were $27.7 million in the third quarter of 2025 which includes a $2.4 million reduction following a voluntary price adjustment on Hytrulo ahead of National Reimbursement Drug List (NRDL) negotiation, compared to $26.5 million in the second quarter of 2025. Sales grew 4.6% quarter over quarter driven by an extension of duration of therapy and increased market penetration.

–ZEJULA was $42.4 million in the third quarter of 2025, compared to $48.2 million for the same period in 2024. Sales were softer due to evolving competitive dynamics within the PARPi class.

–XACDURO, which was launched in the fourth quarter of 2024, was $6.4 million in the third quarter of 2025.

–NUZYRA was $15.4 million in the third quarter of 2025, compared to $10.0 million for the same period in 2024. This growth was supported by increased market coverage and penetration.

•Research and Development (R&D) expenses were $47.9 million in the third quarter of 2025, compared to $66.0 million for the same period in 2024, primarily due to a decrease in licensing fees in connection with upfront and milestone payments.

•Selling, General and Administrative expenses were $70.1 million in the third quarter of 2025, compared to $67.2 million for the same period in 2024. This increase was primarily driven by higher general selling expenses to support the growth of NUZYRA and VYVGART, partially offset by decreases in selling expenses related to ZEJULA.

•Loss from operations was $48.8 million in the third quarter of 2025, $28.0 million when adjusted to exclude certain non-cash expenses including depreciation, amortization, and share-based compensation. A reconciliation of loss from operations (GAAP) to adjusted loss from operations (non-GAAP) is included at the end of this release.

•Net loss was $36.0 million in the third quarter of 2025, or a loss per ordinary share attributable to stockholders of $0.03 (or loss per American Depositary Share (ADS) of $0.33), compared to a net loss of $41.7 million for the same period in 2024, or a loss per ordinary share of $0.04 (or loss per ADS of $0.42). These decreases in net loss were primarily due to increased product revenue and decreased operating expenses.

•Cash and cash equivalents, short-term investments, and current restricted cash totaled $817.2 million as of September 30, 2025, compared to $832.3 million as of June 30, 2025.
