Deadlines vary; a lawyer can confirm yours. An older diagnosis or a past filing window does not, by itself, establish whether you have a claim.

02 · Where cases are heard
Where would my case be heard?
Missouri's 5-year statute of limitations for product liability and the Eastern District of Missouri's reputation as a premier pharmaceutical litigation venue make the state a strategic location for Dupixent CTCL claims. St. Louis has been ground zero for major pharmaceutical verdicts, including multi-billion-dollar talc and Roundup judgments, and the city's experienced mass tort bench and plaintiff-favorable jury pools attract national pharmaceutical litigation. An estimated 48,000 Missouri residents have been prescribed Dupixent since 2017, with prescribing concentrated in the St. Louis and Kansas City metropolitan areas. The Siteman Cancer Center at Washington University/Barnes-Jewish Hospital, an NCI-designated comprehensive cancer center, provides world-class cutaneous lymphoma expertise.
Missouri has two federal judicial districts: the Eastern District (St. Louis) and Western District (Kansas City). The Eastern District of Missouri (St. Louis) has been one of the most significant pharmaceutical litigation venues in the country, managing major cases including Johnson & Johnson talc and Roundup. Missouri follows a pure comparative fault system and does not cap compensatory damages in product liability cases.
