The Pharmacy and Poisons Board (PPB) in Kenya has issued a public alert concerning a falsified batch of the breast cancer drug Phesgo (Pertuzumab/Trastuzumab) found in the market.

• The specific falsified batch identified is Batch Number C5290S20.
• Key organizations involved are the Pharmacy and Poisons Board (PPB) and the drug's manufacturer, Roche.
• A crucial distinguishing detail is that genuine Phesgo is a clear liquid solution, while the counterfeit batch is a white powder that requires reconstitution, which is not how the authentic drug is supplied.
