## TL;DR

Tacquell is a tumour-infiltrating lymphocyte therapy for melanoma developed by the Netherlands Cancer Institute, the academic group whose randomised trial first showed TIL therapy could beat ipilimumab. Europe's medicines committee gave it a negative opinion in June 2026, so it is not authorised.

## Summary

Tacquell (EMA product number EMEA/H/C/006563; marketing authorisation applicant Netherlands Cancer Institute) is described in the EMA register as autologous melanoma-derived tumour-infiltrating lymphocytes, ex vivo expanded, for the treatment of melanoma. The CHMP adopted its opinion on 25 June 2026 and the opinion status on the product page is negative, so there is no EU marketing authorisation. It is an academic TIL product; the linked key paper is the Netherlands Cancer Institute's randomised phase 3 trial of TIL therapy against ipilimumab (NCT02278887). The only other TIL product with a regulatory history in the corpus is lifileucel (Amtagvi), whose EU application was withdrawn in 2025.
