"The TGH Cancer Institute, in collaboration with the USF Health Morsani College of Medicine, is committed to better understanding and advancing otoprotective strategies aimed at preserving auditory function in patients receiving cisplatin chemotherapy," said Gene A. Wetzstein, PharmD, BCOP, Director of Supportive Care Research & Scientific Affairs at the TGH Cancer Institute and principal investigator of the initiative. "This evaluation will examine real-world clinical data and audiology monitoring that will help inform future clinical research and quality efforts in assessing, preventing and managing ototoxicity."

PEDMARK is currently approved for pediatric patients one month of age and older with localized non-metastatic solid tumors and is also recognized by the National Comprehensive Cancer Network with a 2A recommendation for use in AYA patients.

"Real-world evidence plays a critical role in demonstrating the clinical utility of PEDMARK across diverse patient populations and tumor types," said Pierre S. Sayad, PhD, M.S., chief medical officer of Fennec Pharmaceuticals. "As more institutions generate data on its use outside of controlled trials, clinicians will gain a clearer picture of the important role of PEDMARK in providing hearing loss protection for patients receiving cisplatin."

The following sections provide general background information and labeling approved by the U.S. Food and Drug Administration for PEDMARK and are not intended to solicit participation in any research activity.

About Cisplatin-Induced Ototoxicity

Cisplatin and other platinum-based chemotherapies are widely used to treat solid tumors and have been vital in improving survival rates. Unfortunately, these life-saving treatments often result in permanent, irreversible hearing loss, also known as ototoxicity.i

Hearing loss from cisplatin treatment is not rare. Studies show that between 60-90% of patients treated with cisplatin may develop hearing loss, depending upon the dose and duration of chemotherapyii. Many of those treated with cisplatin will require lifelong hearing aids or cochlear implants, which can be helpful for some, but do not reverse the hearing loss and can be costly over time.iii Treatment-induced hearing loss can reduce quality of survivorship as it impacts many aspects of life, such as speech and language skills, academic performance, social-emotional development, career potential and the ability to live independently.iv,v While audiologic monitoring is recommended to help manage ototoxicity, it is currently underutilized in certain cancer patient populations.

PEDMARK (sodium thiosulfate injection)

PEDMARK is the first and only U.S. Food and Drug Administration (FDA) approved therapy indicated to reduce the risk of ototoxicity associated with cisplatin treatment in pediatric patients 1 month of age and older with localized, non-metastatic, solid tumors. It is a unique formulation of sodium thiosulfate in single-dose, ready-to-use vials for intravenous use in pediatric patients. PEDMARK is also the first and only therapeutic agent with proven efficacy and safety data with an established dosing regimen, across two open-label, randomized Phase 3 clinical studies, the Children’s Oncology Group (COG) Protocol ACCL0431 and SIOPEL 6.

Additionally, PEDMARK is recommended for the adolescent and young adult (AYA) population by the National Comprehensive Cancer Network, or NCCN, with a 2A endorsement.

Approximately 500,000 patients in the U.S. are diagnosed annually with cancers that could be treated with a platinum-based chemotherapy.vi,vii The incidence of ototoxicity depends upon the dose and duration of chemotherapy, and many of those treated will require lifelong hearing aids. Until the FDA approval of PEDMARK, there were no preventative agents for this hearing loss. Patients with hearing loss resulting from cancer treatment have a statistically significant worse quality of life compared with peers who have no hearing loss.viii,ix

PEDMARK has been studied by co-operative groups in two Phase 3 clinical studies of survival and reduction of ototoxicity, COG ACCL0431 and SIOPEL 6. Both studies have been completed. The COG ACCL0431 protocol enrolled childhood cancers typically treated with intensive cisplatin therapy for localized and disseminated disease, including newly diagnosed hepatoblastoma, germ cell tumor, osteosarcoma, neuroblastoma, medulloblastoma, and other solid tumors. SIOPEL 6 enrolled only hepatoblastoma patients with localized tumors.

Indications and Usage

PEDMARK (sodium thiosulfate injection) is indicated to reduce the risk of ototoxicity associated with cisplatin in pediatric patients 1 month of age and older with localized, non-metastatic solid tumors.

Limitations of Use

The safety and efficacy of PEDMARK have not been established when administered following cisplatin infusions longer than 6 hours. PEDMARK may not reduce the risk of ototoxicity when administered following longer cisplatin infusions, because irreversible ototoxicity may have already occurred.

Important Safety Information

PEDMARK is contraindicated in patients with history of a severe hypersensitivity to sodium thiosulfate or any of its components.

Hypersensitivity reactions occurred in 8% to 13% of patients in clinical trials. Monitor patients for hypersensitivity reactions. Immediately discontinue PEDMARK and institute appropriate care if a hypersensitivity reaction occurs. Administer antihistamines or glucocorticoids (if appropriate) before each subsequent administration of PEDMARK. PEDMARK may contain sodium sulfite; patients with sulfite sensitivity may have hypersensitivity reactions, including anaphylactic symptoms and life-threatening or severe asthma episodes. Sulfite sensitivity is seen more frequently in people with asthma.

PEDMARK is not indicated for use in pediatric patients less than 1 month of age due to the increased risk of hypernatremia or in pediatric patients with metastatic cancers.

Hypernatremia occurred in 12% to 26% of patients in clinical trials, including a single Grade 3 case. Hypokalemia occurred in 15% to 27% of patients in clinical trials, with Grade 3 or 4 occurring in 9% to 27% of patients. Monitor serum sodium and potassium levels at baseline and as clinically indicated. Withhold PEDMARK in patients with baseline serum sodium greater than 145 mmol/L.

Monitor for signs and symptoms of hypernatremia and hypokalemia more closely if the glomerular filtration rate (GFR) falls below 60 mL/min/1.73m2.

Administer antiemetics prior to each PEDMARK administration. Provide additional antiemetics and supportive care as appropriate.

The most common adverse reactions (≥25% with difference between arms of >5% compared to cisplatin alone) in SIOPEL 6 were vomiting, nausea, decreased hemoglobin, and hypernatremia. The most common adverse reaction (≥25% with difference between arms of >5% compared to cisplatin alone) in COG ACCL0431 was hypokalemia.

On March 4, 2026 Citius Oncology, Inc. ("Citius Oncology") (Nasdaq: CTOR), an oncology-focused biopharmaceutical company and majority-owned subsidiary of Citius Pharmaceuticals, Inc. ("Citius Pharma") (Nasdaq: CTXR), reported positive topline safety and efficacy results from an investigator-initiated Phase 1 trial evaluating LYMPHIR (E7777, denileukin diftitox-cxdl) administered prior to commercial CD19-directed CAR-T therapy in patients with high-risk relapsed or refractory diffuse large B-cell lymphoma (DLBCL). The trial was conducted by lead investigator, Dr. Veronika Bachanova, at the University of Minnesota and City of Hope. Full results were presented at the 2026 ASTCT & CIBMTR Tandem Meetings1.

The Phase 1 trial was designed to augment the lymphodepletion regimen prior to CAR-T infusion through the administration of LYMPHIR to potentially improve the anti-tumor activity of CAR-T therapies. LYMPHIR, an engineered fusion toxin that preferentially binds to the IL-2 receptor expressed on regulatory T-cells (Tregs), is currently FDA-approved and commercially available for the treatment of relapsed or refractory cutaneous T-cell lymphoma (CTCL) after one prior systemic therapy.

"Enhancing Treg depletion prior to CAR-T infusion with LYMPHIR represents a promising immunomodulatory strategy in patients with high-risk DLBCL, and these Phase 1 data provide an encouraging signal of the potential to enhance current CAR-T regimens," said Dr. Myron Czuczman, Executive Vice President and Chief Medical Officer of Citius Oncology and Citius Pharma. "These positive data support our broader strategy of exploring LYMPHIR’s modulatory effect on Tregs in combination with other approved therapies to potentially enhance the body’s own immune system to fight cancerous tumors," he added.

Topline Results & Study Design

● All patients (n=14) completed treatment and proceeded to CAR-T infusion;

● LYMPHIR was well tolerated, with no dose-limiting toxicities observed;

● No Grade ≥3 LYMPHIR-related immune adverse events or infusion reactions were reported; and,

● Data demonstrated effective Treg depletion, and promising efficacy signals of enhanced standard lymphodepletion with the use of Treg-targeting LYMPHIR.

The Phase 1, open-label, dose-escalation study (NCT04855253), enrolled 14 patients with relapsed or refractory DLBCL exhibiting poor prognostic features, including double/triple hit genetics, primary refractory disease, and extranodal involvement. Participants received one dose of LYMPHIR (E7777) at 5, 7, or 9 µg/kg followed by low dose chemotherapy prior to standard commercial CD19-directed CAR-T cell therapy. All patients received an infusion of one of the following FDA-approved, commercially manufactured CAR-T products: axicabtagene ciloleucel (Yescarta; Kite Pharma/Gilead Sciences), lisocabtagene maraleucel (Breyanzi; Bristol Myers Squibb), or tisagenlecleucel (Kymriah; Novartis).

The use of LYMPHIR in this study was investigational and outside of its FDA-approved indication. The Phase 1 study was not designed or powered to evaluate clinical efficacy, and no conclusions can be drawn regarding comparative effectiveness or long-term outcomes.

Key Findings from the Phase 1 Trial

● Overall response rate (ORR) was 86% at one month, including 57% complete responses (CR) and 29% partial responses (PR);

● One-year progression-free survival (PFS) was 77% (95% CI: 43–92%);

● One-year overall survival (OS) was 84% (95% CI: 49–96%);

● A single LYMPHIR dose resulted in depletion of circulating Tregs in all but one patient;

○ Median reduction of 24 Tregs/µL (range 8–65);

○ Treg nadir was observed 24 hours post-LYMPHIR;

● LYMPHIR was well tolerated with no dose-limiting toxicities (DLTs) observed up to 9 µg/kg; and,

● Reported adverse events included manageable Grade 1–2 capillary leak syndrome, fever, and transient liver enzyme elevations; Grade 3 cytopenias were consistent with expected lymphodepletion. CAR-T related cytokine release syndrome (CRS) occurred in 43% of patients (all Grade 1/2), and immune effector cell-associated neurotoxicity syndrome (ICANS) occurred in 21% (primarily low grade).

"In this high-risk population, LYMPHIR showed a favorable safety profile and promising pharmacodynamic effects when administered prior to CAR-T therapies. This data sets the stage for a larger study to assess its potential to enhance CAR-T efficacy through longer duration of LYMPHIR use," said Dr. Veronika Bachanova, Principal Investigator and Professor of Medicine at the University of Minnesota.

Dr. Bachanova presented the topline data at the 2026 Tandem Meetings | ASTCT CIBMTR.

Title: E7777 to Enhance Regulatory T-Cell Depletion Prior to CAR-T for High-Risk LBCL

Presentation ID: 677608

Abstract ID: 296369

About Diffuse Large B-Cell Lymphoma (DLBCL)

Diffuse large B-cell lymphoma (DLBCL) is the most common subtype of non-Hodgkin lymphoma (NHL), accounting for approximately 30%–40% of newly diagnosed cases in the United States. DLBCL is an aggressive and rapidly growing cancer of B lymphocytes, a type of white blood cell responsible for producing antibodies. While frontline chemoimmunotherapy regimens such as R-CHOP can be curative for many patients, up to 40% experience relapse or refractory disease. High-risk features are associated with poor outcomes and limited responses to standard therapies, including CAR-T cell therapy. Novel strategies that modulate the tumor microenvironment, such as transient regulatory T-cell depletion, are under investigation to improve treatment efficacy and long-term remission rates in this difficult-to-treat population.

About LYMPHIR (denileukin diftitox-cxdl)

LYMPHIR is a targeted immune therapy for relapsed or refractory cutaneous T-cell lymphoma (CTCL) indicated for use in Stage I-III disease after at least one prior systemic therapy. It is a recombinant fusion protein that combines the IL-2 receptor binding domain with diphtheria toxin (DT) fragments. The agent specifically binds to IL-2 receptors on the cell surface, causing diphtheria toxin fragments that have entered cells to inhibit protein synthesis. After uptake into the cell, the DT fragment is cleaved and the free DT fragments inhibit protein synthesis, resulting in cell death. Denileukin diftitox-cxdl demonstrated the ability to deplete immunosuppressive regulatory T lymphocytes (Tregs) and antitumor activity through a direct cytocidal action on IL-2R-expressing tumors.

In 2021, denileukin diftitox received regulatory approval in Japan for the treatment of relapsed or refractory CTCL and peripheral T-cell lymphoma (PTCL). Subsequently, in 2021, Citius acquired an exclusive license with rights to develop and commercialize denileukin diftitox in all markets except for India, Japan and certain parts of Asia. LYMPHIR (denileukin diftitox-cxdl) was approved by the FDA and subsequently launched in the U.S. in December 2025.

"2025 was a productive year for Cellectar, marked by disciplined execution across our pipeline and meaningful clinical, regulatory, and operational achievements," said James Caruso, president and CEO of Cellectar. "We advanced iopofosine I-131 toward its planned mid-2026 Conditional Marketing Authorization (CMA) submission in Europe, supported by a strong clinical dataset and productive dialogue with both the European and U.S. regulatory agencies. In parallel, we continued to shape the future of our radiotherapeutic platform with the initiation of our Phase 1b CLR 125 study in triple negative breast cancer and strengthened our supply chain and intellectual property estate."

"As we look ahead to 2026, our momentum is building. We expect important clinical readouts, continued regulatory progress, and expansion of our next-generation Phospholipid Drug Conjugate (PDC) programs. We remain focused on executing with excellence, communicating transparently, and delivering meaningful therapeutic advances for patients with difficult-to-treat cancers," added Mr. Caruso.

2025 and Recent Corporate Highlights

Iopofosine I 131, the Company’s Phospholipid Drug Conjugate (PDC) designed to provide targeted delivery of iodine-131 (radioisotope)
Following advice from the European Medicines Agency’s (EMA) Scientific Advice Working Party (SAWP), the Company plans to submit a CMA for iopofosine I 131 as a treatment for in Waldenström Macroglobulinemia (WM). The CMA submission will be supported by data from the CLOVER WaM study, including 12-month follow-up on all patients, updated overall and major response rates, progression-free survival, duration of response, and compelling subset analyses on post-BTKi patients.
Received Breakthrough Therapy Designation (BTD) from the U.S. Food and Drug Administration (FDA) for iopofosine I 131 in relapsed/refractory WM.
Received recommendation from the FDA to investigate iopofosine I 131 as a treatment option in post-BTKi indications as early as the second line, substantially expanding the available patients in the U.S. market.
CLR 121125 (CLR 125), an iodine-125 Auger-emitting program targeted for solid tumors
Initiated a Phase 1b study of CLR 125 in Triple Negative Breast Cancer (TNBC).
CLR 125 has been well tolerated in vivo with no signs of end-organ toxicity, including hematologic toxicity, and has also demonstrated reduction or inhibition of solid tumors in preclinical studies.
Enrollment is ongoing in the Phase 1b dose finding study of CLR 125, which will evaluate three doses of 32.75 mCi/m2/dose for up to 4 cycles, 62.5 mCi/m2/dose for up to 3 cycles and 95 mCi/m2/dose for up to 2 cycles in patients with relapsed TNBC.
The study’s primary endpoint is to determine a recommended Phase 2 dose and to evaluate safety, tolerability and initial response assessment (RECIST v1.1 and PFS).
Secured a supply agreement with Ionetix to provide commercial-scale supply of cGMP-grade Actinium-225 (Ac-225) and Astatine-211 (At-211) to support ongoing CLR 225 clinical development programs.
Corporate
Strengthened and expanded the Company’s global intellectual property estate with newly issued patents across Europe, Asia-Pacific, the Middle East and the Americas. The expanded IP coverage protects both iopofosine I 131 as well as the broader radiotherapeutic pipeline, including CLR 125.

2025 Financial Highlights

Cash and Cash Equivalents: As of December 31, 2025, the company had cash and cash equivalents of $13.2 million, compared to $23.3 million as of December 31, 2024. The company believes its cash balance as of December 31, 2025, is adequate to fund its basic budgeted operations into the third quarter of 2026.
Research and Development Expenses: R&D expenses for the year ended December 31, 2025, were approximately $11.5 million, compared to approximately $26.1 million for the year ended December 31, 2024. The decrease was primarily a result of reduced activity in our CLOVER WaM clinical study, as we were exclusively in patient follow-up during 2025. Additionally, manufacturing costs declined as we completed development of a fully redundant production and logistics pipeline.
General and Administrative Expenses: G&A expenses for the year ended December 31, 2025, were approximately $11.5 million, compared to approximately $25.6 million for the same period in 2024. The decrease was primarily a result of reduced pre-commercialization efforts and related personnel.
Other income and expense: Other income and expense, net, was approximately $1.2 million of income in 2025, as compared to approximately $7.3 million of income in the prior year. These amounts are almost exclusively a result of non-cash impacts from the cost to issue and in the valuation of certain warrants that are considered liabilities.
Net Loss: Net loss for the full year ending December 31, 2025, was $21.8 million or $8.35 per basic and diluted share, compared with $44.6 million or $36.52 per basic share and $41.89 per diluted share during 2024.
