Esteve gains rights to Sanofi thyroid cancer drug

1 July 2025

Marking a new step forward in its international growth, Spanish privately-held pharma company Esteve has entered into an agreement with Sanofi to acquire French pharma major Sanofi’s (Euronext: SAN) Caprelsa (vandetanib) rights in more than 50 countries, a treatment that is used in adults and children above five years of age to treat aggressive and symptomatic medullary thyroid cancer.

The companies have not disclosed any financial terms of the deal. Sanofi acquired rights to Caprelsa from the UK’s AstraZeneca (LSE: AZN) in 2015, paying the latter around $300 million. The drug had global product sales of $48 million in 2014.
