Experimental: Arm C: 2 courses ipi 3 + 2 courses nivo 3 - Patients receive 2 courses of ipilimumab 3 mg/kg q3wks, directly followed (\> 2 hours and \< 24 hours) by 2 courses nivolumab 3 mg/kg every 2 weeks prior to surgery at week 6. Blood for PBMCs and biopsies will be taken for translation research.

Experimental: PRADO extension cohort - Patients will be treated with 2 courses ipilimumab and nivolumab at the dose level defined as the winner dosing scheme from OpACIN-neo, which is the dosing schedule of arm B.

Surgery and adjuvant therapy

* Patients achieving a pCR or pnCR will not undergo CLND and will not receive any adjuvant treatment. Structural follow-up will be perfomed every 12 weeks by CT, ultrasound of regional lymph nodes.
* Patients achieving a pPR will undergo CLND and start structural follow-up (including CT and physical examination) every 12 weeks thereafter without any adjuvant treatment.
* Patients achieving no response (pNR) will undergo CLND and start at week 12 with adjuvant nivolumab 480mg q4wks for 52 weeks + radiotherapy (according to patient's and physicians' decision). In patients that are BRAF V600E/K mutation positive, adjuvant BRAF+MEK

Summary
Brief summary
This is an open-label three-arm phase 2 trial (including a Simon stage 2 design) consisting of 90 stage III melanoma patients randomized 1:1:1 to receive either 2 courses 3 mg/kg ipilimumab + 1 mg/kg nivolumab every 3 weeks (Arm A), 2 courses 1 mg/kg ipilimumab + 3 mg/kg nivolumab every 3 weeks (Arm B), or 2 courses ipilimumab 3 mg/kg, directly followed by 2 courses nivolumab 3 mg/kg every 2 weeks (Arm C). All three treatment arms are applied prior to surgery at week 6, 30 patients per arm. Patients will be stratified according to treatment center. An interim analysis will be performed after 13 patients have been included in each arm, thus in total 39 patients have been included.

PRADO extension cohort The trial will enroll in total about 100-110 melanoma patients with macroscopic stage III disease (RECIST measurable disease); inclusion will stop when 50 patients have achieved a pCR or pnCR. All patients will be treated (after marker placement into the largest lymph node metastasis) with the winner combination identified in the first part of the OpACIN-neo study which is 2 courses ipilimumab 1mg/kg + nivolumab 3mg/kg, q3wks. After 6 weeks of treatment, the patients will undergo only surgical resection of the marked index lymph node. Thereafter subsequent surgery and adjuvant therapy will be performed according to the achieved pathologic response.
