Christian U. Blank, MD, PhD, on Melanoma: Potentially Practice-Changing Results From the NADINA Trial

NADINA is the first phase III, investigator-initiated trial, testing a combination of neoadjuvant checkpoint inhibition against standard of care adjuvant therapy. NADINA showed that neoadjuvant ipilumumab plus nivolumab is superior to adjuvant nivolumab in the event free survival, showing that 83% at one year are rent-free in case of treated neoadjuvant versus only 57 treated with the standard of care adjuvant therapy. Special about NADINA is also that it has a personalized adjuvant part. Patients achieving a deep response, what we call major pathologic response after the neoadjuvant part, didn't receive any subsequent other therapy, no adjuvant therapy, and started the follow-up at once, and this was the case in nearly 60% of the patients. And despite of only this six weeks of treatment, these patients have an excellent outcome with an event-free survival of 95% at 12 months. Therefore, NADINA established for the first time a neoadjuvant combination scheme for macroscopic melanoma, but it also shows that we should personalize these neoadjuvant therapies, saving toxicity and resources for patients, achieving an excellent response after the neoadjuvant therapy. In that way, it establishes a really novel concept in macroscopic melanoma.
