Is this trial a fit for you?

Likely a good fit

Adults (≥18) with resectable, measurable stage III cutaneous or mucosal melanoma without distant metastases, including those who stopped prior anti-PD-1 therapy >6 months or targeted therapy >3 months ago, are the intended participants.

Probably not a fit

Patients with clinically or radiologically detectable distant metastases, uveal melanoma, hypersensitivity to nivolumab or ipilimumab, or without evaluable disease per RECIST are excluded and unlikely to benefit from this protocol.

What this trial studies

NEO-1 is a multicenter phase II proof-of-concept trial testing intratumoral (image-guided) injections of ipilimumab combined with nivolumab given before surgical resection in patients with resectable stage III cutaneous or mucosal melanoma. The approach aims to concentrate immune checkpoint blockade in the tumor to boost local and systemic anti-tumor immunity while reducing the systemic toxicity seen with full-dose intravenous combination therapy. Fresh blood and tumor samples are collected at baseline and during treatment for PORTRAIT profiling to characterize the tumor microenvironment and identify predictive biomarkers. Patients proceed to planned surgery after the neoadjuvant intratumoral treatment and safety and anti-tumor response are monitored throughout.

Why it matters

Potential benefit: If successful, this approach could shrink tumors and trigger systemic immune responses while reducing the severe systemic side effects associated with intravenous combination immunotherapy.

How similar studies have gone: Systemic neoadjuvant ipilimumab plus nivolumab has shown improved outcomes but high toxicity in randomized trials, and early intratumoral immune-checkpoint blockade studies have produced local and distant responses but remain largely proof-of-concept.
