Dupixent and Cancer: Recent scientific investigations have raised important questions about Dupixent and its potential cancer risks, particularly regarding the development of cutaneous T-cell lymphoma (CTCL). Studies published in 2024 and 2025 have reported higher rates of this rare skin cancer among patients receiving dupilumab treatment. In response to these concerns, the FDA acknowledged the issue in October 2024 by placing Dupixent on its “Potential Signals of Serious Risks” list, which means they will be investigating the reported cases of CTCL. As a result of these developments, individual are filing a Dupixent Cancer Lawsuit against the manufacturers, with plaintiffs claiming that there were insufficient warnings about the potential risks of malignancy.
Dupixent (dupilumab): Is a significant advancement in biologic therapy for patients suffering from chronic inflammatory conditions. It has been approved by the FDA for various uses and works by targeting specific pathways in the immune system to treat conditions such as atopic dermatitis, asthma, chronic rhinosinusitis with nasal polyps, and eosinophilic esophagitis. Dupixent is produced through a collaboration between Sanofi and Regeneron and has experienced great commercial success since its initial approval in March 2017.

Understanding Cutaneous T-Cell Lymphoma (CTCL)
- Cutaneous T-cell Lymphoma: Is a rare type of non-Hodgkin lymphoma that occurs when T-lymphocytes, which are white blood cells responsible for immune defense, become cancerous and accumulate in the skin.
- Slow Progressing Cancer: Unlike more aggressive lymphomas that develop quickly, this slow-growing cancer usually progresses over months or years.
- Laborious Diagnosis: The rarity of CTCL and its varying symptoms make it difficult to diagnose and may lead to delays in starting the right treatment.
Common Cutaneous T-Cell Lymphoma Symptoms
The signs of CTCL often resemble harmless skin conditions, making it challenging for healthcare providers to diagnose. Patients usually present with:
- Persistent itchy, scaly rashes that do not respond to standard dermatological treatments
- Red patches or plaques on the skin, especially in areas protected from the sun such as the buttocks, hips, and lower abdomen
- Raised lesions that may develop into tumors in advanced stages
- Erythroderma, characterized by widespread redness affecting large areas of the body
- Thickened skin with an unusual texture or appearance
Types of CTCL
There are several different subtypes of cutaneous T-cell lymphoma, each with its own clinical features and prognoses:
- Mycosis fungoides is the most common form of CTCL, making up about 50% of all cases. This subtype usually appears as patches and plaques that slowly progress over years, potentially leading to tumor formation in later stages.
- Sézary syndrome is an aggressive variant characterized by widespread erythroderma (redness), swollen lymph nodes (lymphadenopathy), and the presence of cancerous T-cells (Sézary cells) in the bloodstream. This leukemic phase of CTCL causes severe itching and affects the entire body.
- Other subtypes: Include lymphomatoid papulosis, anaplastic large cell lymphoma, subcutaneous panniculitis-like T-cell lymphoma, and primary cutaneous peripheral T-cell lymphoma (unspecified).
Diagnostic Challenges in Lymphoma Diagnosis
- Skin Biopsy: To confirm a diagnosis of CTCL, doctors need to conduct a thorough evaluation using various methods. The main diagnostic procedure is a skin biopsy, which involves examining a small sample of tissue under a microscope to look for specific changes associated with lymphoma. Immunohistochemical staining techniques are used to identify certain markers on T-cells and determine if they are clonal (originating from a single abnormal cell).
- Blood Tests: May be done to check for circulating malignant cells, especially in cases of Sézary syndrome. Imaging studies such as CT scans or PET scans can help assess whether lymph nodes are involved or if there is any spread of disease beyond the skin.
- Multiple Biopsies: In some instances, multiple biopsies may be required to obtain sufficient tissue for accurate diagnosis. Dermatopathologists who specialize in studying lymphoproliferative disorders play a crucial role in interpreting these samples.
- Treatment Side Effects: Unfortunately, some patients may experience unexpected side effects from certain treatments, such as vision loss from medications like Mounjaro. If you or a loved one has faced such issues, it may be beneficial to explore potential legal avenues for compensation through a class action lawsuit. The Law Offices of Timothy L. Miles specializes in these types of cases and can provide assistance.

The Potential Link Between Dupixent and Cancer Risks
- Recent scientific investigations: Have revealed concerning patterns regarding Dupixent cancer risks among patients treated with dupilumab for inflammatory conditions.
- Dupixent and Cancer Risks: Multiple independent studies published between 2024 and 2025 have documented statistically significant associations between Dupixent use and the development of cutaneous T-cell lymphoma.
Emerging Evidence from Clinical Research
- Substantial Dupixent and Cancer Risks: An April 2024 study identified a substantial elevation in CTCL incidence among atopic dermatitis patients receiving dupilumab therapy. The adjusted analysis demonstrated that Dupixent increased CTCL risk by over 300 percent compared to patients not receiving the medication. This finding represented one of the first quantitative assessments of the potential malignancy risk associated with this biologic therapy.
- Dupixent and Cancer Risks Corroborated: Subsequent research in August 2024 corroborated these findings, revealing that Dupixent users were more than 4.5 times more likely to receive a CTCL diagnosis during treatment. The consistency across multiple independent investigations strengthened concerns about the medication’s safety profile regarding lymphoproliferative disorders.
- Clinical Research Expanded: A June 2025 study expanded the scope of investigation to asthma patients, demonstrating that individuals using Dupixent for respiratory conditions faced elevated CTCL risk compared to those receiving alternative asthma medications. This research, published in the European Respiratory Journal, suggested the cancer risk extended beyond dermatological applications to other approved indications.
Pharmacovigilance Data and Reporting Patterns
- FAERS Database: Analysis of the FDA Adverse Event Reporting System (FAERS) database through September 2025 revealed over 300 lymphoma diagnoses reported in association with Dupixent use.
- Significantly Higher Reporting Rates: A May 2025 analysis of this data indicated that Dupixent demonstrated approximately 30 times higher reporting rates for cancer compared to the average pharmaceutical product, representing a significant deviation from expected adverse event patterns.
Regulatory Status and Safety Updates on Dupixent
- Breakthrough Therapy Designation: The regulatory trajectory of dupilumab demonstrates the FDA’s progressive expansion of approved indications across multiple patient populations. The agency granted Breakthrough Therapy designation in November 2014, recognizing the medication’s potential to address unmet medical needs in atopic dermatitis treatment. This designation accelerated the development and review process, culminating in FDA approval for adult eczema treatment in March 2017.
- Subsequent regulatory actions: Expanded the medication’s approved use across diverse age groups and conditions:
-
- October 2018: Approval as add-on asthma treatment for eosinophilic or oral corticosteroid-dependent patients aged 12 and older
- March 2019: Authorization for moderate-to-severe atopic dermatitis in adolescents aged 12-17
- May 2020: Extension to children aged 6-11 with moderate-to-severe atopic dermatitis
- June 2022: Historic approval as the first biologic medicine for moderate-to-severe atopic dermatitis in children aged 6 months to 5 years
- January 2024: Label update for uncontrolled moderate-to-severe hand and foot atopic dermatitis
- FDA Deems Serious Risk: The regulatory landscape shifted significantly in March 2025 when the FDA placed Dupixent on the “Potential Signals of Serious Risks” list following accumulating reports of cutaneous T-cell lymphoma among treated patients. This designation indicates the agency’s active evaluation of potential regulatory actions regarding FDA label updates dupilumab cancer risks. The safety signal emerged from analysis of the FDA Adverse Event Reporting System (FAERS) database, which documented over 300 lymphoma diagnoses by September 2025.
- Regulatory Scrutiny Intensifies: A May 2025 analysis revealed that Dupixent and Cancer reporting rates exceeded the average drug by approximately 30-fold, intensifying regulatory scrutiny. The current product labeling contains no specific warnings regarding CTCL risk, representing a critical gap between emerging safety data and patient information. The FDA’s ongoing evaluation may result in mandatory label modifications, prescribing restrictions, or additional post-market surveillance requirements to address these safety concerns.
