Norgine welcomes TGA registration in Australia of PEDMARQSI® (sodium thiosulfate anhydrous) for the prevention of cisplatin-induced hearing loss in children1

• PEDMARQSI^® is now TGA registered in Australia for the prevention of ototoxicity induced by cisplatin chemotherapy in patients 1 month to <18 years of age with localised, non-metastatic, solid tumours
• TGA registration provides an approved treatment option in an area of significant unmet medical need for children receiving cisplatin chemotherapy

AMSTERDAM, May 6, 2026 /PRNewswire/ -- Norgine, a leading European specialty pharmaceutical company is pleased to announce that PEDMARQSI^® (sodium thiosulfate anhydrous) has been registered by the Australian Therapeutic Goods Administration (TGA) for the prevention of ototoxicity induced by cisplatin chemotherapy in patients 1 month to <18 years of age with localised, non-metastatic, solid tumours.¹

Cisplatin is a widely used and important chemotherapeutic for children with solid tumours, but it carries a substantial risk of permanent hearing loss. Hearing loss in childhood can have profound and lifelong consequences, affecting speech and language development, education, social functioning and overall quality of life.^2,3 PEDMARQSI^® is the first and only treatment registered in Australia for the prevention of cisplatin-induced ototoxicity in paediatric patients.¹

Gus Rudolph, General Manager, Norgine, Australia, said: "The TGA registration of PEDMARQSI^® marks an important milestone for children, families and healthcare professionals in Australia. Cisplatin-induced hearing loss can have lifelong consequences for young patients, and this approval provides an option specifically developed to help prevent this complication in eligible children receiving cisplatin chemotherapy. We are pleased to reach this regulatory milestone and remain focused on working with relevant stakeholders to support access for eligible patients in Australia."

The TGA registration is based on data from two open-label, randomised Phase 3 clinical trials, SIOPEL 6² and COG ACCL0431.³  

"Cisplatin‑induced hearing loss is a well‑recognised and often irreversible complication of paediatric cancer treatment, with significant long‑term implications for communication, learning and quality of life," said Dr. David Gillen, Chief Medical Officer, Norgine. "From a clinical perspective, the ability to proactively address this risk is an important consideration when caring for children receiving cisplatin. The availability of an approved preventive option represents a meaningful development in the supportive care of paediatric oncology patients."

Marketing authorisation for PEDMARQSI^® in Australia adds to previous approvals in other territories, including Paediatric Use Marketing Authorisation (PUMA) granted by the European Medicines Agency in May 2023 and a national marketing authorisation in the United Kingdom, as well as Swissmedic approval in March 2026.^4,5 This milestone further reflects Norgine's ability to navigate regulatory pathways for rare and specialist medicines.
