Primary Outcomes (13)
Part B1: Recurrence Free Survival (RFS)
This is an event driven trial. Recurrence-free survival time (RFS) is computed from the earliest of the date of recurrence or death or, if without recurrence or death, the date last assessed for recurrence without diagnosis of recurrence (censored). The date of recurrence is specified as the first date a recurrence is suspected, which is later confirmed by biopsy.

Part A:To Evaluate the Biological Activity of Seviprotimut-L in Patients With Molecular Weight MW) Range 1 [0,20)
For Part A, immunogenicity of the vaccine was based on anti-melanoma IgG/IgM antibody response at week 10 compared to week 0. A positive result by Western Blot was considered an immunogenic response to study treatment. The response for each participant was calculated based on the average percent change in intensity across these Bins. The definition of response in each participant was the average percent change: \> 0% (meaning any change), or \> 5, 10, 15, 20, and 25%. The bands having data in each Bin is the unit of analysis in each Bin and in all cases corresponds to the number of participants having bands in that Bin. No participant had multiple bands in a single Bin.
Serum was collected for Western blot testing and analysis on Day 0 (baseline) and at Week 10 for WM range 1.
