Dupixent Cancer Lawyers Reviewing Lymphoma Lawsuits Over Hidden Risks
The lawyers at Saiontz & Kirk are now reviewing Dupixent cancer lawsuits for individuals diagnosed with cutaneous T-cell lymphoma (CTCL), Sézary syndrome, or other rare T-cell lymphomas after receiving Dupixent (dupilumab) injections for eczema, asthma, or related conditions.
While Sanofi and Regeneron have promoted their drug as a breakthrough treatment for chronic inflammatory diseases, studies now suggest Dupixent side effects may increase the risk of serious blood cancers. Families who turned to Dupixent for relief from skin or breathing problems are instead confronting unexpected lymphoma diagnoses that were never included in the drug’s warnings.
⚖️ Who May Qualify for a Dupixent Cancer Lawsuit?
Our Dupixent cancer lawyers are investigating claims that Sanofi and Regeneron failed to disclose these risks and deprived patients of the ability to make fully informed decisions about their care.
As a result, we are reviewing cases for individuals who were diagnosed with the following after using Dupixent:
- Cutaneous T-Cell Lymphoma (CTCL)
- Mycosis fungoides
- Sézary syndrome
- Anaplastic large cell lymphoma (ALCL)
- Other rare T-cell lymphoma subtypes
- Wrongful death linked to Dupixent-related lymphoma

Why Individuals Are Turning to Dupixent Lawyers
Dupixent was marketed as a breakthrough therapy for eczema, asthma, and chronic inflammatory conditions. However, emerging medical evidence has linked the injections to serious and sometimes fatal blood cancers, including cutaneous T-cell lymphoma (CTCL) and other rare forms of non-Hodgkin lymphoma.
For individuals who trusted Dupixent, these findings raise two urgent concerns:
- Those who already face a CTCL diagnosis and need legal help recovering compensation.
- Those who remain on Dupixent and fear developing cancer after years of use without proper warnings.
Our law firm is investigating claims for individuals who have been diagnosed with CTCL, or other form of lymphoma after receiving Dupixent injections.
Understanding Dupixent Failure to Warn Lawsuits
Pharmaceutical companies owe a duty of care under the law: they must disclose all known risks and provide adequate warnings to both physicians and patients. When a drug is marketed without these disclosures, it isn’t just a regulatory violation — it is a breach of the trust patients place in their healthcare providers and the companies behind these treatments.
Dupixent lawsuits allege that Sanofi and Regeneron:
- Failed to warn about the association between Dupixent and rare blood cancers, including CTCL.
- Promoted Dupixent as a safe, long-term therapy even as safety signals began to appear in adverse event data and published studies.
- Denied patients and doctors the opportunity to choose safer alternatives, leaving families vulnerable to devastating diagnoses.
The law is clear: when manufacturers withhold risk information, patients are stripped of their ability to make informed medical decisions. In the case of Dupixent, this failure to warn left families blindsided by lymphoma diagnoses that may have been prevented, caught earlier, or avoided entirely had the truth been disclosed.
How Long Do I Have to File a Dupixent Lawsuit?
Every state has a statute of limitations that sets a deadline for filing pharmaceutical injury claims. If a lawsuit is not filed before the deadline expires, patients and families may lose their right to pursue compensation, no matter how strong the case may be. Therefore, it is important to contact a Dupixent lawyer as soon as you discover you may have a claim.
Because many CTCL diagnoses come after years of misdiagnosis as eczema, determining when the clock begins to run can be complex. Courts often consider the date of diagnosis, the date the connection to Dupixent became reasonably knowable, or the date of death in wrongful death claims.
Our attorneys review each situation individually to ensure that all filing deadlines are met and claims are preserved. Contacting a lawyer as soon as possible is the safest way to protect your rights and ensure that evidence, medical records, and expert testimony are secured before they are lost or destroyed.
What Compensation May Be Available in a Dupixent Cancer Lawsuit?
Patients and families affected by Dupixent-related cancers may be entitled to recover compensation for the full scope of their losses. Damages pursued in these lawsuits can include:
- Medical expenses – past and future costs of cancer treatment, hospitalizations, and follow-up care.
- Lost wages and diminished earning capacity – for time away from work and reduced ability to earn income in the future.
- Pain and suffering – compensation for the physical pain, emotional distress, and loss of enjoyment of life caused by lymphoma.
- Wrongful death damages – for families who lost a loved one, including funeral expenses, loss of financial support, and loss of companionship.
By pursuing these claims, our Dupixent injury law firm seeks not only to secure financial support for individual families, but also to hold the manufacturers accountable for placing profits ahead of safety.

Questions Dupixent Clients Often Ask Our Lawyers
As we review Dupixent cancer cases, our clients frequently raise similar concerns. These questions help illustrate what many families want to know when considering a lawsuit:
- Will I owe anything if my case is not successful? No. All Dupixent cases are handled on a contingency fee basis. Our clients never pay upfront fees, and there are no costs unless we secure a recovery.
- Can I still pursue a claim if my cancer was first misdiagnosed as eczema? Yes. Many CTCL cases were initially mistaken for eczema. A delayed or missed diagnosis is part of the legal claim and underscores why patients were placed at greater risk.
- What if my loved one passed away from Dupixent-related lymphoma? Surviving family members may bring a wrongful death claim to pursue damages for medical expenses, funeral costs, lost income, and the loss of companionship.
- How long will my case take? Timelines vary, but Dupixent lawsuits are typically coordinated through multidistrict litigation (MDL). This process streamlines discovery, strengthens negotiating leverage, and helps move cases toward resolution.
- What types of compensation may be available? Potential damages can include past and future medical expenses, lost wages, diminished earning capacity, pain and suffering, and, in wrongful death claims, funeral costs and loss of companionship.
- How do I know if my diagnosis qualifies? Our attorneys will review your medical history, pathology reports, and treatment records during a free consultation to determine whether you meet the criteria for a Dupixent cancer lawsuit.
