A Miami lawyer has obtained a $24 million class action settlement with a Swiss drugmaker that allegedly persuaded doctors to prescribe the expensive AIDS drug Serostim to patients who did not need it.

In 2005, attorney Lance Harke of Harke & Clasby sued drugmaker Serono and its Massachusetts-based subsidiary, Serono Labs, on behalf of Miami Beach AIDS patient Eugene Francis and an estimated 10,000 AIDS patients nationwide. Harke’s co-counsel was Hagens Berman in Boston. The suit was filed in U.S. District Court in Massachusetts.
