Frequently asked questions about Pedmark STS

What is Pedmark STS used for?

Pedmark STS is used for the prevention of cisplatin-induced ototoxicity in patients with solid tumor malignancies, including testicular, head and neck, and thoracic cancers. It is an investigational small molecule being studied in a Phase 2 clinical trial for this purpose.

How does Pedmark STS work?

Pedmark STS works by delivering sodium thiosulfate, which binds to cisplatin in the body and neutralizes its toxic effects on the inner ear, thereby protecting against hearing loss. This mechanism is being evaluated in the ongoing Phase 2 trial for solid tumor malignancies.
