Civil rights attorney Ben Crump and Seeger Weiss have filed another unjust-enrichment lawsuit seeking justice for the estate of Henrietta Lacks, a Black Maryland woman who died of cervical cancer in October 1951—months after undergoing controversial medical treatment.

The lawsuit, filed Monday in Baltimore federal court, accuses defendants Novartis Pharmaceuticals Corp. and Viatris Inc. of commercializing drug products and gene therapy treatments using Lacks’ living genetic material or HeLa cell lines.
