CD30-Positive recurrent or refractory Cutaneous T-Cell Lymphoma

Permanent J-Code (J9161) expected to be effective April 1, 2025 LYMPHIR is approved by the U.S. Food and Drug Administration (FDA) for the treatment of adult patients with relapsed or refractory Stage I-III cutaneous T-cell lymphoma (CTCL) after at least one prior systemic therapy. CRANFORD, N.J., Feb. 6, 2025 /PRNewswire/ -- Citius Pharmaceuticals, Inc. ("Citius Pharma" or the "Company") (Nasdaq: CTXR) and its oncology-focused subsidiary, Citius Oncology, Inc. ("Citius Oncology") (Nasdaq: CTOR), today announced that LYMPHIR™ (denileukin diftitox-cxdl) has been assigned a unique, permanent Healthcare Common Procedure Coding System (HCPCS) J-code (J9161) by the Centers for Medicare & Medicaid Services (CMS). Effective April 1, 2025, healthcare providers may use the permanent J-code, J9161 (Injection, denileukin diftitox-cxdl, for intravenous use, 1 microgram), when submitting claims for LYMPHIR. "The establishment of a permanent J-code marks a critical milestone in supporting patient access to LYMPHIR, providing coding clarity for physicians and facilities who administer LYMPHIR, and facilitating reimbursement. This achievement is a key step in ensuring that LYMPHIR is accessible to patients with commercial and government insurance (VA, DoD, Medicare) coverage," stated Leonard Mazur, Chairman and CEO of Citius Pharma and Citius Oncology. J-codes are unique identifiers utilized by U.S. government and commercial payers, as well as physicians and their office staff, to streamline the billing and reimbursement process for infused therapies and certain other treatments. 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 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 CTCL and PTCL. Subsequently, in 2021, Citius acquired an exclusive license with rights to develop and commercialize LYMPHIR in all markets except for Japan and certain parts of Asia. LYMPHIR was approved by the FDA in August 2024. About Cutaneous T-cell Lymphoma Cutaneous T-cell lymphoma is a type of cutaneous non-Hodgkin lymphoma (NHL) that comes in a variety of forms and is the most common type of cutaneous lymphoma. In CTCL, T-cells, a type of lymphocyte that plays a role in the immune system, become cancerous and develop into skin lesions, leading to a decrease in the quality of life of patients with this disease due to severe pain and pruritus. Mycosis Fungoides (MF) and Sézary Syndrome (SS) comprise the majority of CTCL cases. Depending on the type of CTCL, the disease may progress slowly and can take anywhere from several years to upwards of ten to potentially reach tumor stage. However, once the disease reaches this stage, the cancer is highly malignant and can spread to the lymph nodes and internal organs, resulting in a poor prognosis. Given the duration of the disease, patients typically cycle through multiple agents to control disease progression. CTCL affects men twice as often as women and is typically first diagnosed in patients between the ages of 50 and 60 years of age. Other than allogeneic stem cell transplantation, for which only a small fraction of patients qualify, there is currently no curative therapy for advanced CTCL. INDICATION LYMPHIR is an IL2-receptor-directed cytotoxin indicated for the treatment of adult patients with r/r Stage I-III cutaneous T-cell lymphoma (CTCL) after at least one prior systemic therapy. IMPORTANT SAFETY INFORMATION BOXED WARNING: CAPILLARY LEAK SYNDROME Capillary leak syndrome (CLS), including life-threatening or fatal reactions, can occur in patients receiving LYMPHIR. Monitor patients for signs and symptoms of CLS during treatment. Withhold LYMPHIR until CLS resolves, or permanently discontinue based on severity. WARNINGS AND PRECAUTIONS Capillary Leak Syndrome LYMPHIR can cause capillary leak syndrome (CLS), including life-threatening or fatal reactions. CLS was defined in the clinical trials as the occurrence of at least 2 of the following symptoms at any time during LYMPHIR therapy: hypotension, edema, and serum albumin <3 g/dL. These symptoms were not required to occur simultaneously to be characterized as capillary leak syndrome. As defined, CLS occurred in 27% of patients in the pooled population across 3 clinical trials, including 8% with Grade 3. There was one (0.8%) fatal occurrence of CLS. Of the patients with CLS, 22% had recurrence. The majority of CLS events (81%) occurred within the first 2 cycles of treatment. The median time to onset from Cycle 1, Day 1 was 6.5 days (range: 1 to 77), the median duration of CLS was 14 days (range: 2 to 40), and 75% of patients had resolution. The most common symptoms included edema, hypoalbuminemia, and hypotension. Pleural effusion, pericardial effusion, and dehydration also occurred. Regularly assess patients for weight gain, new onset or worsening of edema, dyspnea, and hypotension (including orthostatic changes). Monitor serum albumin levels prior to the initiation of each cycle of therapy and more often as clinically indicated. Withhold, reduce dose, or permanently discontinue based on severity. If LYMPHIR is withheld, resume LYMPHIR following resolution of CLS and when serum albumin is greater than or equal to 3 g/dL. Visual Impairment LYMPHIR can cause serious visual impairment, including changes in visual acuity and color vision. In the pooled population across 3 clinical trials, visual impairment occurred in 9%, with Grade 1 in 8% and Grade 2 in 1%. The most commonly reported symptom was blurred vision. Of the patients with visual impairment, 67% had resolution of their visual impairment. Perform baseline ophthalmic examination and monitor as clinically indicated. If patients experience symptoms of visual impairment, such as changes in visual acuity, changes in color vision, or blurred vision, refer for ophthalmologic evaluation. Withhold LYMPHIR until visual impairment resolves or permanently discontinue based on severity. Infusion-Related Reactions LYMPHIR can cause serious infusion-related reactions. Infusion-related reactions were reported in 69% of patients in the pooled population across 3 clinical trials of patients who received LYMPHIR, with Grade 3 infusion-related reactions in 3.4% [see Adverse Reactions (6.1)]. Eighty-three percent of infusion-related reactions occurred in Cycles 1 and 2. The most common symptoms included nausea, fatigue, chills, musculoskeletal pain, vomiting, fever, and arthralgia. Premedicate patients for the first three cycles prior to starting a LYMPHIR infusion [see Dosage and Administration (2.3)]. Monitor patients frequently during infusion. For Grade 2 or higher infusion reactions, premedicate at least 30 minutes prior to each subsequent infusion with a systemic steroid for at least 3 cycles. Interrupt or discontinue LYMPHIR based on severity [see Dosage and Administration (2.4)]. Institute appropriate medical management. Hepatotoxicity LYMPHIR can cause hepatotoxicity. In the pooled safety population, elevated ALT occurred in 70% of patients, with Grade 3 ALT occurring in 22%; elevated AST occurred in 64% of patients, with Grade 3 AST elevation occurring in 9%. For Grade 3 events, median time to onset was 8 days (range: 1 to 15 days); median time to resolution was 15 days (range: 7 to 50 days); all cases of Grade 3 ALT or AST elevations resolved [see Adverse Reactions (6.1)]. Elevated total bilirubin occurred in 5% of patients, with Grade 3 occurring in 0.9%. Monitor liver enzymes and bilirubin at baseline and during treatment as clinically indicated. Withhold, reduce dose, or permanently discontinue LYMPHIR based on severity. Embryo-Fetal Toxicity Based on its mechanism of action, LYMPHIR can cause fetal harm when administered to a pregnant woman. Verify the pregnancy status of females of reproductive potential prior to the initiation of LYMPHIR. Advise pregnant women of the potential risk to the fetus. Advise females of reproductive potential to use effective contraception during treatment and for 7 days following the last dose of LYMPHIR. ADVERSE REACTIONS The most common adverse reactions (≥20%), including laboratory abnormalities, are increased transaminases, albumin decreased, nausea, edema, hemoglobin decreased, fatigue, musculoskeletal pain, rash, chills, constipation, pyrexia, and capillary leak syndrome USE IN SPECIFIC POPULATIONS Pregnancy Risk Summary Based on its mechanism of action, LYMPHIR can cause fetal harm when administered to a pregnant woman. There are no available data on the use of LYMPHIR in pregnant women to evaluate for a drug-associated risk. No animal reproductive and developmental toxicity studies have been conducted with denileukin diftitox. Denileukin diftitox-cxdl causes depletion of regulatory T lymphocytes (Treg), immune activation, and capillary leak syndrome, compromising pregnancy maintenance. Advise pregnant women of the potential risk to a fetus. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies are 2-4% and 15-20%, respectively. Lactation Risk Summary No data are available regarding the presence of denileukin diftitox-cxdl in human milk, the effects on the breastfed child, or on milk production. Because of the potential for serious adverse reactions in breastfed children, advise women not to breastfeed during treatment with LYMPHIR and for 7 days after the last dose. Females and Males of Reproductive Potential Based on its mechanism of action, LYMPHIR can cause fetal harm when administered to a pregnant woman. Pregnancy Testing Verify the pregnancy status of females of reproductive potential prior to initiating LYMPHIR. Contraception Females Advise females of reproductive potential to use effective contraception during treatment with LYMPHIR and for 7 days after the last dose. Infertility Males Based on findings in rats, male fertility may be compromised by treatment with LYMPHIR. The reversibility of the effect on fertility is unknown. Pediatric Use Safety and effectiveness of LYMPHIR in pediatric patients have not been established. Geriatric Use Of the 69 patients with Stage I-III r/r CTCL who received LYMPHIR, 34 patients (49%) were 65 years of age and older and 10 patients (14%) were 75 years of age and older. Clinical studies of LYMPHIR did not include sufficient numbers of patients 65 years of age and older to determine whether they respond differently from younger adult patients.

The increase was primarily due to costs associated with pre-launch and market research activities associated with LYMPHIR. General and administrative expenses consist primarily of compensation costs, professional fees for legal, regulatory, accounting and corporate development services, and investor relations expenses. Stock-based Compensation Expense For the full year ended September 30, 2024, stock-based compensation expense was $11.8 million as compared to $6.6 million for the prior year. The increase of $5.2 million is largely due to the grant of options under the Citius Oncology stock plan. Stock-based compensation expense under the Citius Oncology stock plan was $7.5 million during the year ended September 30, 2024, compared to $2.0 million for the year ended September 30, 2023, as the plan was initiated in July 2023. For the years ended September 30, 2024 and 2023, stock-based compensation expense also includes $47,547 and $130,382, respectively, for the NoveCite stock option plan. In fiscal years 2023 and 2024, we granted options to our new employees and additional options to other employees, our directors, and consultants. Net loss Net loss was $39.4 million, or ($5.97) per share for the year ended September 30, 2024, compared to a net loss of $32.5 million, or ($5.57) per share for the year ended September 30, 2023, as adjusted for the reverse stock split. The increase in net loss reflects an increase in operating expense of $5.3 million offset by a decrease of $1.6 million in other income. Operating expense increased due to increases in stock-based compensation and general and administrative expenses, which were offset by decreased research and development expense.
