PEDMARK sales rose 78% in the second quarter, and Fennec is now profitable

Fennec Pharmaceuticals sells PEDMARK, the only FDA-approved drug to reduce the risk of hearing loss from cisplatin chemotherapy in children with localized solid tumors.

Fennec's case rests on PEDMARK, the only FDA-approved drug to reduce cisplatin-related hearing loss in children with localized solid tumors. Net product sales reached $17.2 million in the second quarter, up 78% from a year earlier, and Fennec earned $2.2 million in the first half. A settlement keeps Cipla's generic off the market until September 2033, or earlier in certain circumstances. Further growth depends on wider U.S. use, including young adults, Norgine's European sales and a Japan partner. Cash was $41.2 million at June 30.
