T-Cell Lymphoma After Dupixent?
You may have a claim if all three are true:
- You were prescribed Dupixent (dupilumab), most often for eczema or asthma.
- You were later diagnosed with cutaneous T-cell lymphoma, including mycosis fungoides or Sézary syndrome, or another T-cell lymphoma.
- The diagnosis came after you started the drug.

What Has Happened Since the MDL Was Formed
- June 4, 2026: the federal panel created MDL 3180 in New Jersey. Plaintiffs had asked for the Northern District of Georgia, which then held more Dupixent cases than any other district.
- October 22: the court reportedly appointed the plaintiffs’ leadership.
- October 30: the parties filed proposed orders on case management, direct filing of new cases and depositions.
- November 2: plaintiff-side reports say Judge Quraishi entered a discovery schedule in two phases, starting with whether Dupixent can cause T-cell lymphoma, with plaintiff profile forms beginning December 18.
When Could the Dupixent Cases Settle?
Not for a long while. The litigation is five months old. Before anyone talks about money, the court has to decide whether the science supports the claim that Dupixent can cause T-cell lymphoma. That question comes first in the schedule, and a ruling for the companies could end most cases. Only after it, and usually after the first trials, do settlements become realistic.
Are There Dupixent Settlement Amounts?
No. Nothing has settled and nothing has been tried, so there is no figure to report. What would matter if the cases resolve: the type and stage of lymphoma, the treatment required, how long you took Dupixent before diagnosis, and whether a skin condition treated as eczema was lymphoma all along.
The Science in One Paragraph
A 2024 study in JAMA Dermatology of 19,612 patients found Dupixent users were about four times more likely to develop cutaneous T-cell lymphoma. FDA adverse event data reflected nearly 300 lymphoma reports by January 2026, 138 of them specific to this cancer. Those findings are the basis of the lawsuits; they are not proof in any one case. Our article Does Dupixent Cause Cancer? goes through the evidence and its limits.
What to Do Now
Do not stop a prescribed drug without talking to your doctor. If you were diagnosed with a T-cell lymphoma after taking Dupixent, keep your pharmacy and biopsy records and have your dates checked. Alabama and Georgia generally allow two years and Tennessee one. State pages: Alabama Dupixent lawsuit, Georgia Dupixent lawsuit and Tennessee Dupixent lawsuit.
