Stage II patients with primary surgical treatment of cuMM are often at risk for recurrence of their disease. This risk may be reduced by adjuvant systemic treatment. Due to toxicities of adjuvant therapies the aim is to identify patients at high risk for relapse and to administer adjuvant treatment only to these patients. Thus an optimal balance between insufficient treatment vs. overtreatment has to be found.

To define these patients a prognostic biomarker test will be used in addition to conventional AJCC staging. AJCC staging takes into account several prognostic factors. However, to subdivide stage II melanoma patients into having a low or high risk for relapse further methods are needed.

This clinical trial will evaluate whether adjuvant nivolumab treatment will improve relapse-free survival (RFS) in patients with stage II high-risk melanoma as compared to observation only. The randomized approach of this trial offers the most objective method with the least influence of bias. Since patients with stage II melanoma are usually not receiving adjuvant treatment, no patient will be undertreated in case of randomization into observational arm.


The NivoMela trial is a randomized, controlled, prospective, multi-center national phase III trial with biomarker-based risk stratification.

Stage II melanoma patients having undergone surgery of the malignant melanoma will be screened using the MelaGenix GEP score to identify patients at high risk for relapse. It is expected, that 61% of screened patients will belong to this group.

Patients with a risk score of > 0.0 (HR 1.48, 1.11-1.98) corresponding to high risk of relapse will be randomized at a ratio of 2:1 to receive either nivolumab as adjuvant treatment (arm A) or observation only (arm B).

Stratification factors for randomization are:

  1. Tumor stage: IIA versus IIB versus IIC
  2. Gender: Female versus Male
  3. Site of primary tumor: extremities versus trunk versus head &neck

All screened patients with a risk score of ≤ 0.0 who are not eligible for randomization will be followed for RFS, DMFS and OS for at least 5 years according to German Follow-up guidelines (Arm C).

Various factors that could potentially predict clinical response and incidence of AEs to treatment with nivolumab will be investigated in peripheral blood and tumor specimen taken at baseline. Data from these investigations will be evaluated for associations with clinical efficacy (eg, ORR, PFS, OS) and safety/toxicity (AE). The samples may also be used for exploratory analyses to assess biomarkers associated with melanoma and/or with immunotherapy treatment.
