  • These suggestions help you prepare for a claim check. They are not a firm's acceptance rules.
  • For preparation: note Dupixent use, the reason it was prescribed and the diagnosis you want checked. This does not decide whether a lawyer will accept the case.

The short answer

What changed in June 2026, and what does it mean for me?
The June 4 order sent listed Dupixent cancer cases to New Jersey for shared pretrial work. It did not decide whether the drug caused the cancer. [4]
Which key dates should I ask about?
The transfer date is not a personal filing deadline. Ask a lawyer which time limit applies to your claim and whether another court date affects it. [2]
How many cases did the order describe?
The June order listed 15 cases and seven more that might join. They were in 12 court districts. This is not today’s total. [4]
What is in the dated court log?
On June 4, 2026, the panel sent the listed cases to New Jersey. It left other types of T-cell cancer for later case-by-case checks. [4]

The process

What happens next

  1. 01

    You answer a few questions

    About two minutes. Nothing is sent until you agree on the last step and press submit.

  2. 02

    A lawyer looks at it

    A lawyer at the firm reads your answers and checks them against the current case criteria.

  3. 03

    The firm decides and gets in touch

    If the firm takes your case, you get the terms in writing to read before you sign. You can always say no.

What changed in June 2026, and what does it mean for me?

The June 4 order sent listed Dupixent cancer cases to New Jersey for shared pretrial work. It did not decide whether the drug caused the cancer.

Judge Zahid N. Quraishi was assigned the cases. The group is MDL 3180, meaning a federal group of separate cases with common questions. Your own claim still needs its facts checked.

Which key dates should I ask about?

The transfer date is not a personal filing deadline. Ask a lawyer which time limit applies to your claim and whether another court date affects it.

Use your treatment and diagnosis dates for that discussion. A court schedule for an existing case and the time to start a new claim are different questions.

How many cases did the order describe?

The June order listed 15 cases and seven more that might join. They were in 12 court districts. This is not today’s total.

The order's list identifies the actions it addressed. Some were transferred from outside New Jersey. Ask for a dated court record before relying on a later case-count claim.

What is in the dated court log?

On June 4, 2026, the panel sent the listed cases to New Jersey. It left other types of T-cell cancer for later case-by-case checks.

The order describes CTCL, a skin T-cell cancer, in the claims before it. It does not include every illness after Dupixent merely because the same medicine was used.

What evidence question remains separate from court grouping?

The court grouped shared questions about cause and warnings. Grouping cases is not an answer to those questions and is not a trial result.

A 2024 record study found more skin T-cell cancer diagnoses in treated eczema patients than in matched untreated patients. It cannot establish a personal cause. Shared research may matter to litigation without deciding one person's medical history.

What should I gather before a case update call?

Keep your case number if you have one, and ask which court issued the update. For a new claim, start with your drug and diagnosis dates.

Request missing health records from the treating office; the federal access rule has stated limits. Ask the lawyer to explain fees and expenses in writing before agreeing to representation.

The model fee rule describes what a contingent agreement should explain, including percentages and expenses. It is not a statement of any firm's actual terms or a promise that first contact is free.
