NO Re-excision MelanomA - NORMA 2

Multicenter Phase 3 Randomized Controlled Trial of NO Re-excision MelanomA - NORMA 2

Source: ClinicalTrials.gov · Last updated 15 Apr 2026

Brief summary (registry, in English)

This multicenter, phase III randomized controlled trial evaluates whether omitting re-excision after complete primary excision of cutaneous melanoma affects patient outcomes. A total of 1,749 patients with pT1b-pT4b cutaneous melanoma without evidence of metastases will be randomized to either standard re-excision according to current guidelines or no re-excision. Sentinel lymph node biopsy and adjuvant systemic therapy will be performed as indicated in both groups. The primary objective is to compare relapse-free survival (RFS) between the two groups. Secondary objectives include comparisons of overall survival (OS), local recurrence rates, recurrence of in-transit and lymph node metastases, distant metastasis-free survival (DMFS), surgical morbidity, quality of life, and health economic outcomes.

Who cannot take part

Copied verbatim from ClinicalTrials.gov and grouped by topic. Only the trial team decides who can take part.

Prior treatment

  • History of previous or concurrent (i.e., second primary) invasive melanoma
  • Patient has undergone surgery on a separate occasion to clear the lymph nodes of the probable draining lymphatic field, except for previous SLNB

Other illness

  • Lentigo malignant melanoma (LMM)
  • Spitz melanoma/malignant Spitz tumor melanoma
  • Uncertain diagnosis of melanoma i.e. so-called 'melanocytic lesions of unknown malignant potential' (MELTUMP or STUMP)
  • Any additional solid tumor or hematologic malignancy during the past 5 years with a life expectancy of less than 5 years
  • History of organ transplantation

Other

  • Non-cutaneous melanoma (uveal, mucosal)
  • Acral melanoma
  • Desmoplastic melanoma
  • Neurotropic melanoma
  • Satellites, in-transit melanomas or macroscopic melanoma metastases
  • Other non-SSM or NM subtypes
  • Melanoma removed by shave excision, excogliation or core biopsy
  • Patient has already undergone a local flap reconstruction of the defect after excision of the primary
  • Multiple melanomas

Who the study is looking for

  • Patients must be 18 years or older at time of consent
  • Patients must have an ECOG performance score between 0 and 2
  • Histologically confirmed, stage pT1b - pT4b (TNM AJCC 8th edition) cutaneous primary melanoma
  • Histological subtypes that are eligible are:
    • Superficial Spreading Melanoma (SSM)
    • Nodular Melanoma (NM)
  • The primary melanoma must have been removed by diagnostic excision and must have at least a minimum of 1 mm tumor free margin for invasive melanoma AND any in situ melanoma
  • Patient must provide informed consent and comply with the treatment protocol and follow-up plan
  • Life expectancy of at least 5 years from the time of diagnosis, not considering the melanoma in question, as determined by the investigator
  • A survivor of prior cancer is eligible provided that ALL of the following criteria are met and documented:
    • The patient has undergone potentially curative therapy for all prior malignancies
    • Life expectancy should be at least 5 years and
    • The patient is deemed by their treating physician to be at low risk of recurrence from previous malignancies.
