Summary
Brief summary (as posted)
Currently, there is no widely used adjuvant treatment available to improve survival after surgical excision of a primary melanoma. In a previous study, loco-regional and systemic immune stimulations, as well as favourable clinical outcomes in terms of sentinel lymph node (SLN) tumor status and recurrence-free survival (RFS) in patients with clinical stage I-II melanoma who received a low dose of toll-like receptor 9 (TLR-9) CPG7909 (CpG-B ODN) intradermally at the excision site of the primary tumor prior to SLN biopsy (SNB) were described. In this phase II trial the investigators had investigated the clinical activity of a next-generation CpG-ODN, IMO-2125, and it's ability to induce loco-regional and systemic immune stimulation in pT3-4 cN0M0 melanoma patients who are scheduled to undergo a combined re-excision and SNB is
