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.
