On November 13, 2025 Kura Oncology, Inc. (Nasdaq: KURA) and Kyowa Kirin Co., Ltd. (TSE: 4151) reported the U.S. Food and Drug Administration (FDA) has granted full approval of KOMZIFTI (ziftomenib) for adult patients with relapsed or refractory (R/R) acute myeloid leukemia (AML) with a susceptible NPM1 mutation who have no satisfactory alternative treatment options. KOMZIFTI is the first and only once-daily, oral menin inhibitor approved for R/R NPM1-mutated (NPM1-m) AML, a devastating blood cancer with limited treatment options.

"KOMZIFTI combines compelling efficacy, a favorable safety profile, compatibility with concomitant medications, and convenient once-daily oral administration in a population with few effective treatment options. These features highlight KOMZIFTI’s potential to serve as the menin inhibitor of choice in its approved indication," said Troy Wilson, Ph.D., J.D., President and Chief Executive Officer of Kura Oncology. "Together with our partner, Kyowa Kirin, we remain committed to advancing development of KOMZIFTI across the treatment continuum for AML, where its best-in-class profile offers potential for even greater impact in combination regimens and earlier lines of therapy. We are fully prepared to launch KOMZIFTI today and deliver this new medicine to patients in need."

NPM1 mutations are among the most common founder mutations in AML, occurring in approximately 30% of cases. Historically, approximately 20% of patients with NPM1-m AML do not respond to front-line therapy. Of those who do respond, 70% will relapse within 3 years, most within 12 months. Early relapse and declining survival with each recurrence underscore the urgent need for treatment approaches that deliver lasting remission.

Approval is supported by the pivotal KOMET-001 trial (NCT04067336), which evaluated KOMZIFTI’s safety and efficacy in 112 R/R NPM1-m AML patients. The rate of complete remission (CR) plus CR with partial hematologic recovery (CRh) was 21.4% (95% CI: 14.2, 30.2). The median duration of CR+CRh was 5.0 months (95% CI: 1.9, 8.1) and the median time to first response in patients who achieved a CR or CRh was 2.7 months (range: 0.9 to 15 months). 88% of patients who achieved CR or CRh did so within 6 months of initiating KOMZIFTI. These data from the Prescribing Information are generally consistent with findings recently published in the Journal of Clinical Oncology.1

"KOMZIFTI addresses a critical need for adult patients with R/R NPM1-m AML, many of whom are older and unable to tolerate intensive chemotherapy or transplant," said Eunice Wang, M.D., Chief of the Leukemia Service and Professor of Oncology at Roswell Park Comprehensive Cancer Center. "The clinical data demonstrate deep and durable responses with a manageable safety profile, including no drug-drug interactions and no Boxed Warnings for QTc prolongation or Torsades de Pointes – key advantages for patients on multiple concurrent medications. This approval equips physicians with a new oral therapy to integrate into care and improve outcomes for this vulnerable patient population."

The most common adverse reactions (≥20%), including laboratory abnormalities, were aspartate aminotransferase increased, infection without an identified pathogen, potassium decreased, albumin decreased, alanine aminotransferase increased, sodium decreased, creatinine increased, alkaline phosphatase increased, hemorrhage, diarrhea, nausea, fatigue, edema, bacterial infection, musculoskeletal pain, bilirubin increased, potassium increased, differentiation syndrome, pruritus, febrile neutropenia, and transaminases increased. KOMZIFTI includes a Boxed Warning for differentiation syndrome, a well-studied mechanism-based risk in drugs that restore differentiation. Absence of clinically meaningful drug-drug interactions can ease the use of KOMZIFTI with concomitant therapies, including those that cause QTc interval prolongation. QTc interval prolongation was ≤ Grade 3 in 12% of patients and no Grade 4 or Grade 5 QTc interval prolongation was reported. QTc interval prolongation of any cause occurred in 10% of the 70 patients 65 years of age or older.

"The approval of KOMZIFTI underscores our commitment to advancing precision medicines to address the genetic drivers of disease in hematology and oncology," said Takeyoshi Yamashita, Ph.D., Executive Vice President and Chief Medical Officer of Kyowa Kirin. "In AML, where many patients face severe disease progression and limited treatment options, the evolution toward targeted therapies such as KOMZIFTI represents a major step forward and offers potential to transform existing standards of care. We are proud to partner with Kura Oncology in bringing this important therapy to patients and their families."

In November 2024, Kura Oncology and Kyowa Kirin entered into a global strategic collaboration to develop and commercialize KOMZIFTI. The collaboration builds on Kyowa Kirin’s leadership and expertise in hematologic malignancies. Under the terms of the collaboration, Kura leads development, regulatory and commercial strategy in the U.S. and is responsible for manufacturing KOMZIFTI. The companies will jointly perform certain commercialization activities in accordance with a co-created U.S. territory commercialization plan. Outside the U.S., Kyowa Kirin leads development, regulatory and commercial strategy and is responsible for commercializing KOMZIFTI.

As part of its commitment to helping patients access KOMZIFTI, Kura has established a support program, Kura RxKonnect, to minimize barriers to access and reimbursement for appropriate patients prescribed KOMZIFTI. Kura RxKonnect is available 8:00 am – 8:00 pm ET by phone at (844) KuraPSP (844-587-2777) or online at www.KuraRxKonnect.com.

Conference Call and Webcast
Kura will host a conference call and webcast featuring Company management and guest speaker Eunice Wang, M.D., Chief of the Leukemia Service and Professor of Oncology at Roswell Park Comprehensive Cancer Center, at 12:30 pm ET / 9:30 am PT on November 13, 2025. The live webcast and replay will be available on the Company’s website at www.kuraoncology.com under the Investors tab in the Events and Presentations section.

About KOMZIFTI
KOMZIFTI (ziftomenib) is an oral menin inhibitor approved for the treatment of adult patients with relapsed or refractory acute myeloid leukemia (AML) with a susceptible NPM1 mutation who have no satisfactory alternative treatment options.

KOMZIFTI is in development for the front-line treatment of AML harboring NPM1 mutations, KMT2A translocations and FLT3 mutations, with the potential to be combined with approved therapies and benefit a broad spectrum of patients earlier in their disease course.

IMPORTANT SAFETY INFORMATION FOR KOMZIFTI FROM THE U.S. PRESCRIBING INFORMATION

Boxed WARNING: DIFFERENTIATION SYNDROME

Differentiation syndrome, which can be fatal, has occurred with KOMZIFTI. Signs and symptoms may include fever, joint pain, hypotension, hypoxia, dyspnea, rapid weight gain or peripheral edema, pleural or pericardial effusions, pulmonary infiltrates, acute kidney injury, and rashes. If differentiation syndrome is suspected, interrupt KOMZIFTI, and initiate oral or intravenous corticosteroids with hemodynamic and laboratory monitoring until symptom resolution; resume KOMZIFTI upon symptom improvement.

WARNINGS AND PRECAUTIONS

Differentiation Syndrome

KOMZIFTI can cause fatal or life-threatening differentiation syndrome (DS). DS is associated with rapid proliferation and differentiation of myeloid cells. Symptoms of DS, including those seen in patients treated with KOMZIFTI, may include fever, hypoxia, joint pain, hypotension, dyspnea, rapid weight gain or peripheral edema, pleural or pericardial effusions, acute kidney injury, and rashes.

In the clinical trial, DS occurred in 29 (26%) of 112 patients with R/R AML with an NPM1 mutation who were treated with KOMZIFTI at the recommended dosage. DS was Grade 3 in 13% and fatal in two patients. In broader evaluation of all patients with any genetic form of AML treated with KOMZIFTI monotherapy in clinical trials, DS occurred in 25% of patients. Four fatal cases of DS occurred out of 39 patients with KMT2A-rearranged AML treated with KOMZIFTI. KOMZIFTI is not approved for use in patients with KMT2A-rearranged AML.

In the 112 patients with an NPM1 mutation, DS was observed with and without concomitant hyperleukocytosis, in as early as 3 days and up to 46 days after KOMZIFTI initiation. The median time to onset was 15 days. Two patients experienced more than one DS event. Treatment was interrupted and resumed in 15 (13%) patients, while it was permanently discontinued in 2 (2%) patients.

Prior to starting treatment with KOMZIFTI, reduce the WBC counts to less than 25 x 10⁹/L. If DS is suspected, interrupt KOMZIFTI, initiate oral or intravenous corticosteroids (e.g., dexamethasone 10 mg every 12 hours) for a minimum of 3 days with hemodynamic and laboratory monitoring. Resume treatment with KOMZIFTI at the same dose level when signs and symptoms improve and are Grade 2 or lower. Taper corticosteroids over a minimum of 3 days after adequate control or resolution of symptoms. Symptoms of DS may recur with premature discontinuation of corticosteroid treatment.

QTc Interval Prolongation

KOMZIFTI can cause QTc interval prolongation. In the clinical trial, QTc interval prolongation was reported as an adverse reaction in 12% of 112 patients treated with KOMZIFTI at the recommended dosage for R/R AML with an NPM1 mutation. QTc interval prolongation was Grade 3 in 8% of patients. The heart-rate corrected QT interval (using Fridericia’s method) (QTcF) was greater than 500 msec in 9% of patients, and the increase from baseline QTcF was greater than 60 msec in 12% of patients. KOMZIFTI dose reduction was required for 1% of patients due to QTc interval prolongation. QTc prolongation occurred in 14% of the 42 patients less than 65 years of age and in 10% of the 70 patients 65 years of age or older.

Correct electrolyte abnormalities, including hypokalemia and hypomagnesemia, prior to treatment with KOMZIFTI. Perform an ECG prior to initiation of treatment with KOMZIFTI, and do not initiate KOMZIFTI in patients with QTcF > 480 msec. Perform an ECG at least once weekly for the first four weeks on treatment, and at least monthly thereafter. Interrupt KOMZIFTI if the QTc interval is > 500 ms or the change from baseline is > 60 ms (Grade 3). In patients with congenital long QTc syndrome, congestive heart failure, electrolyte abnormalities, or those who are taking medications known to prolong the QTc interval, more frequent ECG monitoring may be necessary. Concomitant use of KOMZIFTI with drugs known to prolong the QTc interval may increase the risk of QTc interval prolongation, result in a greater increase in the QTc interval and adverse reactions associated with QTc interval prolongation, including Torsades de Pointes, other serious arrhythmias, and sudden death.

Embryo-Fetal Toxicity

Based on findings in animals and its mechanism of action, KOMZIFTI can cause embryo-fetal harm when administered to a pregnant woman. Advise pregnant women of the potential risk to the fetus. Advise females of reproductive potential to use effective contraception during treatment with KOMZIFTI and for 6 months after the last dose. Advise males with female partners of reproductive potential to use effective contraception during treatment with KOMZIFTI and for 3 months after the last dose.

ADVERSE REACTIONS

Fatal adverse reactions occurred in 4 (4%) patients who received KOMZIFTI, including 2 with differentiation syndrome, 1 with infection, and 1 with sudden death. Serious adverse reactions were reported in 79% of patients who received KOMZIFTI. Serious adverse reactions occurring in ≥ 5% of patients included infection without an identified pathogen (29%), febrile neutropenia (18%), bacterial infection (16%), differentiation syndrome (16%), and dyspnea (6%).

Dosage interruption of KOMZIFTI due to an adverse reaction occurred in 54% of patients. Adverse reactions that required dose interruption in ≥ 2% of patients included infection without an identified pathogen (15%), differentiation syndrome (13%), febrile neutropenia (5%), pyrexia (4%), electrocardiogram QT prolonged (4%), leukocytosis (4%), bacterial infection (3%), cardiac failure (2%), cholecystitis (2%), diarrhea (2%), pruritus (2%), and thrombosis (2%). Dose reduction of KOMZIFTI due to an adverse reaction occurred in 4% of patients. Permanent discontinuation of KOMZIFTI due to an adverse reaction occurred in 21% of patients. Adverse reactions that required permanent discontinuation of KOMZIFTI in ≥ 2% of patients were infection without an identified pathogen (8%), bacterial infection (4%), cardiac arrest (2%), and differentiation syndrome (2%).

Most common (≥ 20%) adverse reactions, including laboratory abnormalities, were aspartate aminotransferase increased (53%), infection without an identified pathogen (52%), potassium decreased (52%), albumin decreased (51%), alanine aminotransferase increased (50%), sodium decreased (49%), creatinine increased (45%), alkaline phosphatase increased (41%), hemorrhage (38%), diarrhea (36%), nausea (35%), fatigue (34%), edema (30%), bacterial infection (28%), musculoskeletal pain (28%), bilirubin increased (27%), potassium increased (26%), differentiation syndrome (26%), pruritus (23%), febrile neutropenia (22%), and transaminases increased (21%).

DRUG INTERACTIONS

Drug interactions may occur when KOMZIFTI is concomitantly used with:

Strong or Moderate CYP3A4 Inhibitors: Monitor patients more frequently for KOMZIFTI-associated adverse reactions.
Strong or Moderate CYP3A4 Inducers: Avoid concomitant use of KOMZIFTI.
Gastric Acid Reducing Agents: Avoid concomitant use of KOMZIFTI with proton pump inhibitors (PPIs), H2 receptor antagonists (H2RAs), or locally acting antacids. If concomitant use with H2RAs or locally acting antacids cannot be avoided, modify KOMZIFTI administration time.
Take KOMZIFTI 2 hours before or 10 hours after administration of an H2 receptor antagonist.
Take KOMZIFTI 2 hours before or 2 hours after administration of a locally acting antacid.
Drugs that Prolong the QTc Interval: Avoid concomitant use of KOMZIFTI. If concomitant use cannot be avoided, obtain ECGs when initiating, during concomitant use, and as clinically indicated. Interrupt KOMZIFTI if the QTc interval is > 500 ms or the change from baseline is > 60 ms.
USE IN SPECIFIC POPULATIONS

Pregnancy: Based on findings in animals and its mechanism of action, KOMZIFTI can cause embryo-fetal harm when administered to a pregnant woman. Advise pregnant women of the potential risk to a fetus. Verify pregnancy status in females of reproductive potential prior to starting KOMZIFTI.

Lactation: Because of the potential for adverse reactions in the breastfed child, advise women not to breastfeed during treatment with KOMZIFTI and for 2 weeks after the last dose.

Infertility: Based on findings in animals, KOMZIFTI may impair fertility in females and males of reproductive potential.

"As we advance our robust pipeline of innovative masked immunotherapies, we continue to provide additional validation of our proprietary masking technology and ability to deliver differentiated molecules across a wide range of targets and design formats," said René Russo, Pharm.D., president and chief executive officer of Xilio. "At SITC (Free SITC Whitepaper), we presented compelling data across our clinical and preclinical programs, including data supporting the best-in-class potential of our masked T cell engager programs to meaningfully widen the therapeutic window relative to non-masked T cell engagers as well as our unique ability to incorporate co-stimulation to substantially improve the durability of T cell response."

Dr. Russo added, "For our clinical-stage programs, we continue to be encouraged by the promising data for both vilastobart and efarindodekin alfa, which have each shown differentiated clinical efficacy and safety for patients with high unmet need. In particular, new data for vilastobart leveraging plasma TMB as a predictive biomarker showed a 40% response rate in patients with MSS mCRC without liver metastases, supporting the significant opportunity for vilastobart as a combination therapy. As we look ahead to 2026, we are focused on execution across our clinical programs, while rapidly advancing XTX501, our bispecific PD-1/IL-2, toward a planned IND submission in mid 2026 and our masked T cell engager programs into IND-enabling studies."

Pipeline and Business Updates

Vilastobart: tumor-activated, Fc-enhanced anti-CTLA-4

Vilastobart is currently being evaluated in combination with atezolizumab (Tecentriq) in Phase 1C combination dose escalation in patients with advanced solid tumors and in a Phase 2 clinical trial in patients with microsatellite stable (MSS) metastatic colorectal cancer (mCRC).

•
In November 2025, Xilio announced new late-breaking data from its ongoing Phase 2 clinical trial at the Society for Immunotherapy of Cancer (SITC) (Free SITC Whitepaper) 40th Annual Meeting. These data demonstrated a 40% objective response rate (ORR) in heavily pre-treated, plasma tumor mutational burden (TMB) high patients (≥10 mutations/Mb) with MSS mCRC without liver metastases and showed a statistically significant correlation (p=0.05) between plasma TMB status and response. Approximately 55% of patients with MSS mCRC are estimated to have high plasma TMB, representing a meaningful patient population with high unmet need. For more information, read the press release here, and watch a replay of the webcast with leading colorectal cancer experts here.

•
In November 2025, Xilio announced additional new Phase 2 data presented at SITC (Free SITC Whitepaper), which demonstrated the potential for circulating tumor DNA (ctDNA) as an early predictive biomarker for response to treatment with vilastobart in combination with atezolizumab in patients with MSS mCRC. For more information, read the press release here.

•
Based on the promising clinical activity and safety profile demonstrated by vilastobart as a combination therapy, including in patients who had high plasma TMB, Xilio is actively seeking a partner to develop vilastobart in combination with PD-(L)1 or PD1-VEGF in MSS CRC and other tumor types.

Efarindodekin Alfa: tumor-activated IL-12

Xilio is evaluating efarindodekin alfa as a monotherapy in an ongoing Phase 1/2 clinical trial in patients with advanced solid tumors.

•
In November 2025, Xilio presented Phase 1 monotherapy dose escalation data for efarindodekin alfa at SITC (Free SITC Whitepaper) demonstrating promising monotherapy anti-tumor activity in patients with advanced solid tumors as well as a generally well-tolerated safety profile at doses over 100-fold greater than the maximum tolerated dose of recombinant human IL-12. For more information, read the press release here.

•
In September 2025, Xilio announced the selection of an initial recommended phase 2 dose (RP2D) and schedule for efarindodekin alfa and initiated patient dosing in the Phase 2 portion of the clinical trial. In connection with the initiation of Phase 2, Xilio achieved a development milestone of $17.5 million under its license agreement with Gilead Sciences, Inc. (Gilead). For more information, read the press release here.

•
Xilio has completed enrollment in the Phase 1A monotherapy dose escalation and Phase 1B monotherapy dose expansion portions of the ongoing Phase 1/2 clinical trial, and evaluation of those patients is ongoing.

XTX501: bispecific PD-1 / masked IL-2

XTX501 is a novel, bispecific PD-1 / masked IL-2 designed to selectively stimulate PD-1 positive, antigen-experienced T cells and enhance their function. XTX501 incorporates masking designed to overcome IL-2 receptor-mediated clearance and peripheral activity. In preclinical studies, XTX501 demonstrated robust monotherapy activity (including in settings insensitive to PD-1) and tumor-selective pharmacodynamics consistent with its intended mechanism of action.

•
XTX501 is currently advancing through investigational new drug (IND)-enabling studies, and Xilio plans to submit an IND application for XTX501 in the middle of 2026.

Masked T Cell Engager Programs

Xilio is leveraging its proprietary, clinically validated tumor-activation platform to advance multiple preclinical programs for masked T cell engagers, including wholly owned programs targeting tumor-associated antigens for PSMA (prostate cancer), CLDN18.2 (gastric, pancreatic, esophageal and lung cancers) and STEAP1 (prostate, colorectal and lung cancers), as well as an additional program in collaboration with AbbVie Group Holdings Limited (AbbVie).

Xilio’s masked T cell engager programs include bispecific molecules designed using its advanced tumor-activated cell engager (ATACR) format, which consists of a T cell engager with a masked CD3 targeting domain, and tri-specific molecules designed using its selective effector-enhanced cell engager (SEECR) format. The SEECR format builds upon the ATACR format by adding co-stimulatory signaling designed to further enhance potency and durability of T cell activation.

•
In November 2025, Xilio presented new preclinical data at SITC (Free SITC Whitepaper) highlighting the potential for the company’s masking technology to significantly expand the therapeutic window for T cell engagers and overcome the challenges associated with current, systemically active non-masked T cell engagers. Xilio’s masked T cell engager molecules demonstrated potent anti-tumor activity with evidence of reduced systemic toxicity in murine models, supporting its broad applicability and potential best-in-class profile across a diverse range of targets, and the incorporation of co-stimulatory signaling in Xilio’s proprietary SEECR format enhanced durability of anti-tumor activity compared with T cell engager molecules that lacked co-stimulation. For more information, read the press release here.

•
In the third quarter of 2025, Xilio nominated a development candidate for its PSMA program (ATACR format).

•
Xilio anticipates nominating development candidates for its CLDN18.2 program (ATACR format) in the fourth quarter of 2025 and for its STEAP1 program (SEECR format) in the first half of 2026.

•
Xilio anticipates advancing at least two of these programs into IND-enabling studies and submitting IND applications for those programs in 2027.

Bispecific TCE Overview

For the selected target, LabGenius has developed a selectivity-enhanced TCE. The company’s lead optimisation platform, EVA, was used to discover and concomitantly optimise a TCE with improved killing selectivity, potency, efficacy, and manufacturability. The biological mechanism underlying this enhanced selectivity is based on the principle of avidity. By harnessing avidity-driven selectivity, the optimised TCE can distinguish between healthy and diseased cells based on differential tumour-associated antigen expression.

"We continue to make strong progress both in our commercial and clinical activities," said Shaun Bagai, CEO of RenovoRx. "On the commercial side, we are encouraged by the continued RenovoCath clinical adoption we are seeing in the field. Year-to-date revenue, through the end of the third quarter, was approximately $900,000, reflecting the growing clinical need and market demand for targeted drug-delivery solutions. Since organically launching commercial sales less than a year ago, we have expanded from five centers at the start of 2025 to 14 leading cancer centers now approved to purchase RenovoCath, including several that have already made repeat orders."

"With the recent hiring of Philip Stocton as Senior Director of Sales & Market Development and two regional sales managers, we are building the foundation for sustained growth while maintaining a lean operating structure and prudent capital deployment philosophy," continued Mr. Bagai. "Our team remains laser-focused on strategic, data-driven expansion and is encouraged by the increasing physician-to-physician advocacy for our TAMP (Trans-Arterial Micro-Perfusion) platform as we continue to position RenovoRx for long-term success. Our mission continues with the goal of integrating an approach to therapeutic drug-delivery into the standard of care and ultimately improving patient outcomes by offering a more targeted and tolerable treatment path."

"On the clinical side, we continue to advance our Phase III TIGeR-PaC trial towards enrollment completion in early 2026 and final data readout in 2027, and we’ve successfully launched a new post-marketing registry study from which we expect to garner real-world evidence on the use of the RenovoCath device. We look forward to continuing our progress in the Phase III trial and post-market registry study as we seek to drive value for our shareholders," concluded Mr. Bagai.

Commercialization Update

RenovoRx continued to execute on its RenovoCath commercialization strategy in the third quarter of 2025, demonstrating progress as year-to-date revenue grew to approximately $900,000. Although small revenue fluctuations can be expected quarter-by-quarter at this early stage of commercialization, the positive trends of expanding approved cancer center customers and increasing clinical adoption are very promising.

As of November 7, 2025, RenovoRx has expanded from five cancer center customers approved to purchase RenovoCath at the start of the year to 14 customers. These include additional high-volume National Cancer Institute (NCI)-designated cancer centers and community hospitals. The growth in patient procedures using RenovoCath at five active centers has led to an increase in repeat purchase orders, underscoring both physician satisfaction and growing demand. In addition to these 14 centers now approved to purchase RenovoCath, the Company has delivered product quotes to 10 additional leading centers across the nation, bringing the total to 24 centers who have formally requested quotes for RenovoCath. In addition, RenovoRx has engaged with dozens of physicians, both at various medical conferences and within their institutions, who have expressed commercial interest in utilizing RenovoCath for their patients.

Since organically launching commercial sales less than a year ago without a dedicated sales and marketing team, RenovoRx has achieved early commercial traction that reflects the strong clinical need for targeted drug-delivery solutions designed to reduce systemic toxicity and improve quality of life. The Company’s small but growing team has established a diverse domestic geographic network of academic institutions, NCI-designated cancer centers, and high-volume community hospitals, both successfully implementing and interested in utilizing RenovoCath-enabled TAMP technology.

RenovoRx continues to collect valuable market insights, including sales cycle trends, activation timelines, customer preferences, and other commercial data, as the Company seeks to grow its customer base, fulfill repeat RenovoCath orders, and build a strong foundation for long-term commercial growth. These insights from the first year of commercialization will inform the Company’s strategy and execution plans heading into 2026.

To strengthen and expand the Company’s commercial efforts, in August 2025, RenovoRx announced the hiring of Philip Stocton as Senior Director of Sales and Market Development. Mr. Stocton brings more than 25 years of MedTech leadership, including a decade focused on interventional oncology. His expertise has been invaluable as the Company continues to broaden its footprint across the U.S., while maintaining a lean operating structure. In alignment with the existing budget and to respond to growing demand, the Company has added two regional sales managers and plans to add a marketing director to drive additional physician engagement by the end of the year.

RenovoRx continues to estimate that the initial total addressable market (TAM) for RenovoCath as a stand-alone device represents an approximately $400 million peak annual U.S. sales opportunity, with long-term, several-billion-dollar potential as the platform expands into additional solid tumor indications.

RenovoRx recently launched a commercial website for clinicians and staff to learn more about the RenovoCath device, as well for patients to find treatment cancer centers, which can be accessed here: View Source

Clinical Research and Scientific Programs Update

In the third quarter of 2025, RenovoRx continued advancing its ongoing Phase III TIGeR-PaC clinical trial evaluating the novel drug-device combination oncology product candidate (intra-arterial gemcitabine delivered via RenovoCath, known as IAG). The trial remains on track, with enrollment expected to be completed in early 2026 and final data anticipated in 2027. Enabled by the RenovoCath device, TAMP is designed to deliver therapeutic agents across the arterial wall near the tumor site to bathe the target tumor, potentially optimizing local drug concentration while minimizing systemic exposure and related toxicities versus the standard of care, systemic intravenous therapy. TIGeR-PaC remains the cornerstone of RenovoRx’s clinical development program, validating its mechanism of action and safety profile through rigorous, long-term evaluation.

RenovoRx strengthened its Scientific Advisory Board during the third quarter with the additions of renowned surgeon and pancreatic cancer expert, Dr. Timothy Donahue, Director of the Agi Hirshberg Center for Pancreatic Diseases, Chief of the Division of Surgical Oncology at the David Geffen School of Medicine, and Garry Shandling Chair in Pancreatic Surgery at UCLA, and Dr. Thierry de Baère, Head of Interventional Radiology at the Gustave Roussy Cancer Centre and University Paris-Saclay in France.

During the third quarter, RenovoRx advanced its broader clinical programs. The Company’s post-marketing registry study continues to progress, generating real-world data on the safety and effectiveness of RenovoCath in patients with solid tumors. In September, the first registry-eligible patient procedure was initiated at the University of Vermont Cancer Center, with Baptist Health Miami Cancer Institute and the University of Pittsburgh Medical Center joining as additional study sites.

The Company also continues to support investigator-initiated trials in borderline resectable and oligometastatic pancreatic cancer. These capital-efficient studies are designed to be cost-neutral while providing meaningful data that may further broaden the application for the TAMP therapy platform.

Financial Highlights for the Third Quarter Ended September 30, 2025

Revenue: RenovoRx reported third quarter revenues of approximately $266,000, driven by both new customer orders and repeat purchases of the RenovoCath device. The quarter ended on September 30, 2025 marked the Company’s third full quarter of revenue generation from RenovoCath sales.

Cash Position: As of September 30, 2025, the Company had $10.0 million in cash and cash equivalents. Based on its current operating plan, RenovoRx believes this cash is sufficient to fund ongoing commercialization efforts for RenovoCath and the completion of enrollment in its Phase III TIGeR-PaC clinical trial in early 2026.

R&D Expenses: Research and development expenses were $1.7 million for the quarter ended September 30, 2025, remaining relatively unchanged from the same period in the prior year, reflecting continued investment in the TIGeR-PaC trial as well as support for investigator-initiated and registry studies.

SG&A Expenses: Selling, general, and administrative expenses were approximately $1.7 million for the quarter ended September 30, 2025, compared to $1.2 million for the same period in the prior year.

Net Loss: Net loss was $2.9 million for the quarter ended September 30, 2025, compared to a net loss of $2.5 million for the quarter ended September 30, 2024.

Shares Outstanding: As of November 7, 2025, common shares outstanding totaled approximately 36.6 million.
