"I’m very pleased to report an outstanding quarter in which Revuforj and Niktimvo generated a combined $34 million in net sales. We believe this success is a reflection of excellent commercial execution and the clinical profile of these first- and best-in-class medicines," said Michael A. Metzger, Chief Executive Officer. "We’ve also made excellent progress advancing our pipeline, including most notably the recent submission of our sNDA for R/R mNPM1 AML and the initiation of the first pivotal frontline trial of a menin inhibitor in combination with venetoclax and azacitidine for mNPM1 and KMT2Ar AML. With a solid financial position and highly skilled team, we are poised to deliver two successful product launches while aggressively advancing our development strategy designed to unlock the multi-billion-dollar opportunities for both drugs."

Recent Business Highlights and Anticipated Milestones

Revuforj (revumenib)

Achieved $20.0 million in Revuforj net revenue in the first quarter of 2025, the first full quarter of the U.S. launch. Revuforj was launched in the U.S. in late November 2024 for the treatment of relapsed or refractory (R/R) acute leukemia with a KMT2A translocation in adult and pediatric patients one year and older.
Completed the submission of a supplemental New Drug Application (sNDA) to the U.S. FDA in April 2025, seeking Priority Review for the approval of Revuforj for the treatment of R/R mutant NPM1 (mNPM1) AML. The sNDA was submitted under the FDA’s Real-Time Oncology Review (RTOR) program, which allows for a more efficient review and close engagement between the sponsor and FDA throughout the submission process. The sNDA is supported by the previously reported positive pivotal data from the AUGMENT-101 trial.
Submitted the pivotal R/R mNPM1 AML data from the AUGMENT-101 trial for publication. The manuscript has been accepted and the publication is expected imminently.
Opened enrollment in the EVOLVE-2 trial, a pivotal, randomized, double-blind, placebo-controlled trial of revumenib in combination with venetoclax and azacitidine in newly diagnosed mNPM1 or KMT2A-rearranged (KMT2Ar) AML patients who are unfit for intensive chemotherapy in the first quarter of 2025. The trial is being conducted in collaboration with the HOVON network, a leading cooperative clinical trial group with extensive experience studying novel therapies for hematologic malignancies.
Multiple trials evaluating revumenib in mNPM1 and KMT2Ar acute leukemia across the treatment landscape are ongoing. These trials include:
BEAT AML: A Phase 1 trial evaluating the combination of revumenib with venetoclax and azacitidine in newly diagnosed mNPM1 or KMT2Ar AML patients. The trial is being conducted as part of the Leukemia & Lymphoma Society’s Beat AML Master Clinical Trial. Updated data that showed an overall response rate (ORR)1 of 100% (37/37) and a composite complete remission (CRc) rate of 95% (35/37) were reported at the Company’s investor event at the 66th ASH (Free ASH Whitepaper) Annual Meeting. The Company anticipates that an update on the trial will be available at a medical meeting in the second quarter of 2025.
SAVE: A Phase 1/2 trial evaluating an all-oral combination of revumenib with venetoclax and decitabine/cedazuridine in pediatric and adult patients with R/R AML or mixed-lineage acute leukemia (MPAL) harboring either mNPM1, KMT2Ar, or NUP98r alterations. The trial is being conducted by investigators from MD Anderson Cancer Center. Updated data that showed an ORR of 82% (27/33) and a CR/CRh rate of 48% (16/33) were presented at the 66th ASH (Free ASH Whitepaper) Annual Meeting. The trial is now enrolling a cohort of newly diagnosed patients.
Intensive chemotherapy: A Phase 1 trial evaluating the combination of revumenib with intensive chemotherapy (7+3) followed by revumenib maintenance treatment in newly diagnosed mNPM1 or KMT2Ar acute leukemia patients. The Company expects to report data in the fourth quarter of 2025.
Break Through Cancer: A Phase 2 trial studying whether the combination of revumenib and venetoclax can eliminate MRD in patients with AML and extend progression-free survival. The trial is being conducted by Break Through Cancer, a collaboration between leading U.S. cancer research centers.
INTERCEPT: A Phase 1 trial evaluating the use of novel therapies, including revumenib, to target MRD and early relapse in AML. The trial is being conducted by the Australasian Leukaemia and Lymphoma Group as part of the INTERCEPT AML master clinical trial. Data that showed 54% (6/11) of patients had MRD reduction at any time, including 36% (4/11) who achieved MRD negativity, were presented at the 66th ASH (Free ASH Whitepaper) Annual Meeting.
The Company plans to initiate multiple trials of revumenib in combination with standard of care regimens in newly diagnosed acute leukemia patients who are fit to receive intensive chemotherapy, starting in the second half of 2025.
The Company is evaluating revumenib in patients with R/R metastatic microsatellite stable (MSS) colorectal cancer (CRC). The Phase 1b portion of this proof-of-concept trial is ongoing.
Niktimvo (axatilimab-csfr)

Niktimvo achieved $13.6 million in net revenue in the first quarter of 2025, the first partial quarter of the U.S. launch. Niktimvo was launched in the U.S. in late January for the treatment of chronic graft-versus-host disease (GVHD) after failure of at least two prior lines of systemic therapy in adult and pediatric patients weighing at least 40 kg (88.2 lbs). Syndax and Incyte co-commercialize Niktimvo, and Syndax records 50% of the Niktimvo net profit/loss, defined as net product revenue minus the cost of sales and commercial expenses.
Presented a post-hoc analysis evaluating the effects of prior lines of therapy on clinical outcomes for patients with chronic GVHD in the AGAVE-201 trial of axatilimab. The data show that overall response rates were consistent with axatilimab regardless of the number of prior lines of therapy and that organ-specific responses were noted regardless of the last prior therapy. The data were presented at the 2025 Tandem Meetings of the American Society for Transplantation and Cellular Therapy and the Center for International Blood and Marrow Transplantation Research.
Two trials evaluating axatilimab in combination with standard of care therapies in newly diagnosed chronic GVHD patients are ongoing, including:
A Phase 2, open-label, randomized, multicenter trial of axatilimab in combination with ruxolitinib in patients ≥ 12 years of age with newly diagnosed chronic GVHD.
A pivotal Phase 3, randomized, double-blind, placebo-controlled, multi-center trial of axatilimab in combination with corticosteroids in patients ≥ 12 years of age with newly diagnosed chronic GVHD.
Enrollment is ongoing in the MAXPIRe trial, a Phase 2, 26-week randomized, double-blinded, placebo-controlled trial of axatilimab on top of standard of care in patients with idiopathic pulmonary fibrosis (IPF). The Company expects to complete enrollment in the trial in 2025 with topline data anticipated in the second half of 2026.
First Quarter 2025 Financial Results

As of March 31, 2025, Syndax had cash, cash equivalents, and short and long-term investments of $602.1 million and 86.3 million common shares and prefunded warrants outstanding.

In the first quarter of 2025, the first full quarter of the U.S. launch, Revuforj net revenue was $20.0 million. Cost of sales for the first quarter of 2025 was $0.9 million.

In the first quarter of 2025, the first partial quarter of the U.S. launch, the Company’s partner, Incyte, reported $13.6 million in Niktimvo net revenue. Syndax records 50% of the Niktimvo net commercial profit/loss, defined as net product revenue (recorded by Incyte) minus the cost of sales and commercial expenses. For the first quarter of 2025, Niktimvo posted a net commercial loss and Syndax’s share of the collaboration loss amounted to $0.2 million.

First quarter 2025 research and development expenses increased to $61.6 million from $56.5 million for the comparable prior year period. The year-over-year increase was due to an increase in axatilimab-related costs primarily driven by the IPF trial, the frontline chronic GVHD trial with ruxolitinib being conducted in partnership with Incyte, and a $10.0 million milestone payment as a result of the first patient dosed in the Phase 3 trial of axatilimab in combination with corticosteroids. The higher expenses were also driven by an increase in personnel costs and other expenses related to increased R&D support for ongoing clinical trials, sNDA activities, and medical affairs in support of commercialization. These activities were partially offset by a decrease in revumenib-related costs, primarily driven by an $8.0 million milestone expense in the 2024 period and a reduction in CMC expense due to the capitalization of inventory for commercial use.

First quarter 2025 selling, general and administrative expenses increased to $41.0 million from $23.0 million for the comparable prior year period. The year-over-year increase was primarily due to increased employee-related expenses and professional fees to support increased sales and marketing-related expenses related to the U.S. commercial launch of Revuforj.

For the three months ended March 31, 2025, Syndax reported a net loss attributable to common stockholders of $84.8 million, or $0.98 per share, compared to a net loss attributable to common stockholders of $72.4 million, or $0.85 per share, for the comparable prior year period.

Financial Guidance

For the second quarter of 2025, the Company expects research and development expenses to be $70 to $75 million and total research and development plus selling, general and administrative expenses to be $110 to $115 million. For the full year of 2025, the Company continues to expect research and development expenses to be $260 to $280 million and total research and development plus selling, general and administrative expenses to be $415 to $435 million, which includes an estimated $45 million in non-cash stock compensation expense. The Company is not providing revenue guidance at this time.

Syndax expects that its cash, cash equivalents and short- and long-term investments, combined with its anticipated product revenue and interest income, will enable the company to reach profitability.

About Revuforj (revumenib)

Revuforj (revumenib) is an oral, first-in-class menin inhibitor that is FDA approved for the treatment of relapsed or refractory (R/R) acute leukemia with a lysine methyltransferase 2A gene (KMT2A) translocation in adult and pediatric patients one year and older.

Revumenib is in development for the treatment of R/R acute myeloid leukemia (AML) with a nucleophosmin 1 mutation (mNPM1). Positive pivotal data from the AUGMENT-101 trial in this population with revumenib as a monotherapy were recently reported and the Company submitted a supplemental NDA for revumenib in R/R mNPM1 AML in April 2025. Additionally, multiple trials of revumenib in combination with standard-of-care agents in mNPM1 AML or KMT2A-rearranged acute leukemia are ongoing across the treatment landscape, including in newly diagnosed patients.

Revumenib was previously granted Orphan Drug Designation for the treatment of AML, ALL and acute leukemias of ambiguous lineage (ALAL) by the U.S. FDA and for the treatment of AML by the European Commission. The U.S. FDA also granted Fast Track designation to revumenib for the treatment of adult and pediatric patients with R/R acute leukemias harboring a KMT2A rearrangement or NPM1 mutation and Breakthrough Therapy Designation for the treatment of adult and pediatric patients with R/R acute leukemia harboring a KMT2A rearrangement.

About Niktimvo (axatilimab-csfr)

Niktimvo (axatilimab-csfr) is a first-in-class colony stimulating factor-1 receptor (CSF-1R)-blocking antibody approved for use in the U.S. for the treatment of chronic graft-versus-host disease (GVHD) after failure of at least two prior lines of systemic therapy in adult and pediatric patients weighing at least 40 kg (88.2 lbs).

In 2016, Syndax licensed exclusive worldwide rights to develop and commercialize axatilimab from UCB. In September 2021, Syndax and Incyte entered into an exclusive worldwide co-development and co-commercialization license agreement for axatilimab in chronic GVHD and any future indications.

Axatilimab is being studied in frontline combination trials in chronic GVHD, including a Phase 2 combination trial with ruxolitinib (NCT06388564) and a Phase 3 combination trial with steroids (NCT06585774). Axatilimab is also being studied in an ongoing Phase 2 trial in patients with idiopathic pulmonary fibrosis (NCT06132256).

About the Real-Time Oncology Review Program (RTOR)

RTOR provides a more efficient review process for oncology drugs to ensure that safe and effective treatments are available to patients as early as possible, while improving review quality and engaging in early iterative communication with the applicant. Specifically, it allows for close engagement between the sponsor and the FDA throughout the submission process and it enables the FDA to review individual sections of modules of a drug application rather than requiring the submission of complete modules or a complete application prior to initiating review.

Can-Fite is a recognized leader in the development of small-molecule therapeutics targeting the A3 adenosine receptor (A3AR), which is highly expressed in both inflammatory and cancer cells. Namodenoson, an orally bioavailable A3AR agonist, is currently enrolling patients in a pivotal Phase III study for advanced liver cancer. It has demonstrated selective targeting of liver and pancreatic tumor cells while sparing healthy tissue. Piclidenoson, also an orally administered A3AR agonist, is in a pivotal Phase III trial for patients with moderate-to-severe psoriasis.

Both candidates have shown favorable safety profiles, anti-cancer and anti-inflammatory properties, and promising efficacy in previous Phase II trials. Cumulative funding has also supported drug manufacturing, regulatory activities with the FDA and EMA, and the development of a broad patent portfolio providing extensive intellectual property protection.

In addition to its lead programs, Can-Fite is conducting a Phase IIa study of Namodenoson in pancreatic cancer, following successful preclinical studies demonstrating its ability to inhibit tumor growth by modulating the Wnt/β-catenin, NF-κB, and RAS signaling pathways. A Phase IIb trial in metabolic dysfunction-associated steatohepatitis (MASH) is also underway under an open IND with the FDA, leveraging Namodenoson’s hepatoprotective effects.

To date, Can-Fite has signed seven commercialization agreements with strategic partners for the future marketing of its drug candidates upon regulatory approval. Can-Fite continues to engage with potential partners and seeks to sign additional commercialization agreements in the future.

Motti Farbstein, CEO of Can-Fite, commented: "This funding milestone reflects the strong confidence our investors and partners have in Can-Fite’s scientific platform and clinical strategy. Progressing into pivotal Phase III trials marks a significant step toward bringing innovative, oral therapies to patients with serious unmet needs in liver cancer and psoriasis."

TuHURA Biosciences, Inc. Initiates Phase 1b/2a Study of IFx-Hu2.0 as an Adjunctive Therapy to Keytruda® (pembrolizumab) in First Line Treatment for Metastatic Merkel Cell Carcinoma of Unknown Primary Origin (MCCUP)

On May 5, 2025 TuHURA Biosciences, Inc. (NASDAQ:HURA) ("TuHURA" or the "Company"), a Phase 3 immune-oncology company developing novel technologies to overcome resistance to cancer immunotherapy, reported the initiation of its Phase 1b/2a trial of IFx-Hu2.0, TuHURA’s lead innate immune agonist, in patients with MCCUP who would not be eligible for the Company’s planned Phase 3 accelerated approval trial, which is targeted to begin enrollment later in Q2 2025 (Press release, TuHURA Biosciences, MAY 5, 2025, View Source [SID1234652520]). IFx-Hu2.0 is designed to overcome primary resistance to checkpoint inhibitors (CPIs) like Keytruda and has demonstrated systemic anti-tumor specific immune responses (abscopal effect) when injected intratumorally into cutaneous, subcutaneous, or accessible nodal lesions in its prior Phase 1 and 1b trials in melanoma and advanced or metastatic Merkel cell carcinoma (MCC).

"Like our planned Phase 3 accelerated approval trial, this Phase 1b/2a trial will also investigate the ability of IFx-Hu2.0 to increase the anti-tumor response rate when used alongside Keytruda in first line treatment of CPI naïve, metastatic MCC. However, unlike the planned Phase 3 study, these are patients without skin lesions who present with metastatic deep-seated tumors in the liver, lungs or retropertitoneum (abdomen). Up to 30% of patients with MCC present without primary lesions in the skin, so this trial will not only provide safety, feasibility, and efficacy data, but may also expand the potential number of addressable patients who may benefit from IFx-Hu2.0," said James Bianco, M.D., President and Chief Executive Officer of TuHURA Biosciences.

"If feasibility and safety is demonstrated for IFx-Hu2.0 and Keytruda when radiologically administered to deep-seated tumors, we plan to extend enrollment to a variety of non-MCC cancers that are known not to respond or respond poorly to CPIs. Since the underlying biology of why tumors don’t respond to CPIs is for the most part the same, then the mechanism of how IFx-Hu2.0 overcomes that resistance to CPIs should be independent of the type of cancer treated. We have previously demonstrated that IFx-Hu2.0 can overcome CPI resistance in melanoma, squamous cell, and Merkel cell carcinoma, three unrelated types of skin cancers. If successful, this trial could expand the potential benefit of IFx-Hu2.0 to a wide variety of cancers," added Dr. Bianco.

The Phase 1b/2a trial of IFx-Hu2.0 is a multicenter, open-label trial designed to assess the safety and feasibility of IFx-Hu2.0 as adjunctive therapy to pembrolizumab in adult patients with non-cutaneous MCC. The trial is designed to enroll a total of nine non-cutaneous MCC patients with either hepatic, pulmonary, or retroperitoneal lesions, enrolling three patients per lesion type (NCT06940440). Each patient will receive IFx-Hu2.0 (0.1 mg) injected into a single visceral tumor once a week for three weeks. Within 48 hours of the first IFx-Hu2.0 injection, patients will receive pembrolizumab, followed by pembrolizumab every three weeks for six months. The primary endpoint of the study is safety and feasibility of IFx-Hu2.0 adjuvant therapy evaluated 28 days following the last dose of IFx-Hu2.0, or Day 49 from the first IFx-Hu2.0 infusion. The study will also evaluate key secondary endpoints, including efficacy per RECIST 1.1 criteria at three months and six months. Data from the trial is anticipated by the end of Q4 2025 or early Q1 2026.

TuHURA is also preparing to initiate a single, randomized, placebo-controlled Phase 3 accelerated approval trial of IFx-2.0 administered as an adjunctive therapy to Keytruda (pembrolizumab) versus Keytruda plus placebo in first-line treatment for checkpoint inhibitor-naïve patients with advanced or metastatic MCC (NCT06947928). The primary endpoint in the Phase 3 trial will be overall response rate (ORR) at approximately 24 weeks, with a secondary endpoint of progression free survival (PFS) per RECIST 1.1 criteria. The Company has reached agreement with U.S. Food and Drug Administration (FDA) on requirements for lifting a partial clinical hold on this trial and believes it will meet the requirements in Q2 2025. TuHURA currently anticipates initiating the Phase 3 registrational trial in Q2 2025.

Based on data generated in TuHURA’s Phase 1b trial of IFx-Hu2.0 in CPI naïve patients with advanced or metastatic MCC who progressed receiving CPI therapy, FDA’s Oncology Center of Excellence (OCE), consistent with the FDA’s Project Front Runner Initiative, asked the Company to consider a first-line randomized placebo controlled trial of Keytruda plus placebo or IFx-Hu2.0. The FDA also agreed that the trial could be conducted under their accelerated approval pathway with the use of Objective Response Rate (ORR) as the primary endpoint. The FDA also asked the Company to consider incorporating into its accelerated approval trial a key secondary end point of Progression Free Survival (PFS), which, if successfully achieved without a detriment to overall survival at the time of analysis, may result in the Company not being required to conduct a post approval confirmatory trial, and this single trial could potentially fulfill requirement for regular approval. The Company and the FDA have entered into a Special Protocol Assessment Agreement for the planned Phase 3 trial.

The interim clinical data from Theralase’s multicenter Phase II Bacillus Calmette-Guérin ("BCG")-Unresponsive Non-Muscle Invasive Bladder Cancer ("NMIBC") Carcinoma In-Situ ("CIS") study ("Study II") was presented by Dr. Girish Kulkarni in podium presentations. Dr. Kulkarni, M.D., Ph.D., FRCSC is a urologic surgeon in the Department of Surgical Oncology, Princess Margaret Cancer Centre, University Health Network, a professor in the Department of Surgery at the University of Toronto and the lead principal investigator in the Theralase study.

The interim clinical data presented represents world-class safety and efficacy in the treatment of BCG-Unresponsive NMIBC CIS with a light-activated small molecule. Numerous patients have demonstrated durations of response of 3 years or greater, with 1 patient demonstrating a duration of response of over 7 years, after a single treatment.

Study II Interim Clinical Data1:
Theralase has enrolled and treated 79 patients in Study II, who have been provided the primary Study Procedure (therapeutic dose of Theralase’s lead small molecule RuvidarTM light-activated by the TLC-3200 medical laser system), with completion of enrollment expected by mid-2025.

81% (64/79) of treated patients have completed the clinical study or have been prematurely removed by the PI according to the clinical study protocol are used in the efficacy analysis below.

Performance to Primary Objective:
For the primary endpoint, 62.5% (40/64) of patients treated demonstrated a Complete Response ("CR") (negative cystoscopy and negative urine cytology) at any point in time).

Including patients, who demonstrated an Indeterminate Response ("IR") (negative cystoscopy and positive or suspicious urine cytology), the Total Response increases to 68.8% (44/64).

Primary Endpoint Performance (CR at any Point in Time)
# % Confidence Interval (95%)
Complete Response ("CR") 40 62.5% [43.1, 81.9]
Total Response (CR and IR) 44 68.8% [48.5, 89.1]
Performance to Secondary Objective:
For the secondary endpoint, 45.0% (18/40) of patients, who achieved a CR, maintained their CR response for at least 12 months (450 days from date of Study Procedure).

Secondary Endpoint Performance (Duration of CR) (450 Days)
# % Confidence Interval (95%)
Complete Response ("CR") 18 45.0% [24.2, 65.8]
Performance to Tertiary Objective:
For the tertiary endpoint, 100% (64/64) of patients experienced no Serious Adverse Events ("SAEs") directly related to the Study Drug or Study Device.

Tertiary Endpoint Performance (Safety) (450 Days)
# %
Safety 64 100.0%
25.0% (10/40) of patients who achieved a CR, continue to demonstrate a CR at 24 months from the date of the Study Procedure.

20.0% (8/40) of patients who achieved a CR continue to demonstrate a CR at 36 months from the date of the Study Procedure.

33% (1/3) of patients enrolled in the Phase Ib NMIBC clinical study2 treated once with the Study Procedure has demonstrated a sustained CR lasting over 7 years.

Serious Adverse Events

For 79 patients treated in Study II, there have been 15 Serious Adverse Events ("SAEs") reported:

1 – Grade 1 (resolved within 9 days)
3 – Grade 2 (resolved within 1, 1 and 33 days, respectively)
7 – Grade 3 (resolved within 1, 2, 3, 4, 4, 82 and unknown days, respectively)
3 – Grade 4 (resolved within 3, 6 and 8 days, respectively)
1 – Grade 5
Theralase believes all SAEs reported to date are unrelated to the Study II Drug or Study II Device.

Pending regulatory approval, this innovative technology represents a significant opportunity for an advancement in bladder cancer treatment, with only one treatment, by providing a safe and effective therapy for patients, who have exhausted their standard of care therapeutic options and are facing radical cystectomy (bladder removal).

Arkady Mandel, M.D., Ph.D., D.Sc., Chief Scientific Officer, Theralase stated, "I am delighted that the interim clinical data of Study II continues to demonstrate both high safety and high efficacy in the treatment of patients diagnosed with BCG-Unresponsive NMIBC CIS. Management of BCG-Unresponsive NMIBC CIS is and remains an unmet need and I look forward to the completion of enrollment in the clinical study this summer, which pending regulatory approval could provide an opportunity for patients to receive this treatment as part of routine clinical practice in both Canada and the United States. What we have learned in our research is that Theralase’s light-activated small molecule, Ruvidar, is able to destroy cancer through the production of reactive oxygen species and stimulation of the immune system by blocking multiple immune checkpoints, such as: CD474 (a dominant macrophage checkpoint signal on cancer cells that signals the immune system whether to destroy them or leave them alone), PD-L15 (a protein that acts as a "brake" on the immune system, preventing T cells from attacking cancer cells) and the recently discovered reduction of deubiquitinating enzymes6 (an important class of enzymes, which have been linked to numerous cancers and neurogenerative diseases)."

Roger DuMoulin-White, B.Sc., P.Eng., Pro.Dir., President and Chief Executive Officer, Theralase stated, "The presentation of the interim clinical data to the urological community at the major Canadian and American conferences provides the global urologist community and healthcare professionals, an opportunity to see firsthand the strong clinical data that the uro-oncologists involved in the clinical study have been able to deliver with the Theralase technology. RuvidarTM has proven to be a very versatile small molecule, with its ability to destroy cancer, bacteria and viruses, when activated by light, radiation, sound or even other drugs. Pending regulatory approval, the latest clinical data presented supports the use of light-activated Ruvidar by the urology community to safely and effectively treat patients inflicted with BCG-Unresponsive NMIBC CIS, helping to revolutionize the treatment landscape for bladder cancer. As Theralase wraps up the Phase II NMIBC clinical study in 2025 with a Health Canada and FDA regulatory submission planned in late 2026, I look forward to working with our world-class scientists, researchers and medical doctors in the commencement of numerous new clinical studies, focused on hard to treat viral infections, such as herpes simplex virus lesions (cold sores), through to some of the deadliest and most difficult to treat cancers in the world, such as: glioblastoma multiforme, non-small cell lung cancer, pancreatic cancer, leukemia, muscle invasive bladder cancer and colorectal cancer."

About Carcinoma In-Situ:
CIS of the bladder is an aggressive type of NMIBC characterized as a flat, high-grade tumour confined to the urothelial layer. NMIBC comprises approximately 75% to 80% of all bladder cancers, with CIS found in about 10% of cases.7

Management of CIS of the bladder remains a complex and challenging endeavor due to its high rate of recurrence and progression.
