Exhibit 99.1

 

Citius Pharmaceuticals, Inc. and Citius Oncology, Inc. Announce LYMPHIR™ (Denileukin Diftitox-cxdl) Added to National Comprehensive Cancer Network (NCCN) Clinical Practice Guidelines in Oncology

 

CRANFORD, N.J., Sept. 5, 2024 -- Citius Pharmaceuticals, Inc. (“Citius Pharma” or the “Company”) (Nasdaq: CTXR) and Citius Oncology, Inc. (“Citius Oncology”) (Nasdaq: CTOR), today announced that LYMPHIR™ has been added to the NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines^®). LYMPHIR is included based on an NCCN Category 2A recommendation which indicates a uniform NCCN consensus that the drug is appropriate as an option for patients with Cutaneous T-cell Lymphoma (CTCL).

 

LYMPHIR (denileukin diftitox-cxdl), a novel immunotherapy for the treatment of relapsed or refractory CTCL after at least one prior systemic therapy, was recently approved by the U.S Food and Drug Administration (FDA). The approval of LYMPHIR is based on results from the Phase 3 Pivotal Study 302 (NCT01871727) of CTCL patients who had previously received at least one systemic treatment. LYMPHIR is the only CTCL therapy that targets the interleukin-2 (IL-2) receptor found on malignant T-cells and Tregs.

 

“The inclusion of LYMPHIR in the NCCN Guidelines is a testament to the clinical evidence supporting this therapy, and further supports healthcare professionals in considering LYMPHIR as part of the recommended treatment protocols for CTCL. We are grateful to the NCCN board for its recognition of LYMPHIR, paving the way for expanded access to this important treatment option,” stated Leonard Mazur, CEO of Citius Pharma and Citius Oncology.

 

“NCCN guidelines are widely regarded as the gold standard for clinical decision-making in oncology and hematology, influencing treatment practices and payor reimbursement in the U.S. We believe that LYMPHIR has the potential to improve CTCL patient outcomes, and expect its addition to the NCCN Guidelines may aid adoption and ease reimbursement, particularly for the anticipated patients that qualify for Center for Medicare and Medicaid (CMS) coverage,” added Mazur.

 

About LYMPHIR™ (denileukin diftitox-cxdl)

 

LYMPHIR is a targeted immune therapy for r/r (R/R) 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.

 

 

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. 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.
