Neo-adjuvant Immunotherapy in Patients With Localized Melanoma

Is NCT07230613 recruiting? Yes, currently enrolling (May 2026). This Phase 2 trial studies multiple treatments including Ipilimumab (YervoyTM, 50 mg/10 mL solution) and Nivolumab (OpdivoTM, 40 mg/4mL solution) for cutaneous melanoma, stage iii.

Treatment: Ipilimumab (YervoyTM, 50 mg/10 mL solution) · Nivolumab (OpdivoTM, 40 mg/4mL solution) — The success of anti-PD-1 and anti-CTLA-4 therapies has initiated a paradigm shift in oncology, with drugs now targeting the immune system rather than cancer cells to stimulate the antitumor immune response. Intratumoral (IT) delivery of immunostimulating agents reduces the systemic toxicity associated with monoclonal antibodies (mAbs) targeting immune checkpoints. Notably, IT injections of immune checkpoint blockade (ICB) have been shown to induce immune-mediated tumor responses both at the injected site and at distant, non-injected tumor sites. While surgery has traditionally been the preferred treatment for stage III and IV melanoma patients, neoadjuvant therapy with anti-CTLA-4 and anti-PD-1 agents has shown promising efficacy. In patients with localized melanoma, it is hypothesized that IT administration of ipilimumab (anti-CTLA-4 Ab) combined with nivolumab (anti-PD-1 Ab) will provide the most effective and safe treatment combination. The NEO-1 study is a proof-of-concept clinical trial designed as a sub-protocol of NEOREM master protocol (NCT07262489) to validate the intratumoral immunotherapy approach, aiming to maximize the dose/efficacy ratio of combined ipilimumab and nivolumab treatment while minimizing systemic adverse events. This is an academic, open-label, multicentric, phase II clinical trial evaluating the efficacy and safety of intratumoral injections of ipilimumab and nivolumab combination as neoadjuvant treatment in localized stage III resectable cutaneous or mucosal melanoma patients. Baseline and on-treatment PORTRAIT profiling, as described in the NEOREM Master Protocol (NCT07262489), will be performed using fresh blood and tumor samples. This profiling will reveal the immune status of patients and support biomarker-driven preselection for future trials.
