|Melanoma Lymph Node Cancer||Drug: CMP-001 Biological: Nivolumab||Phase 2|
Patients are being asked to take part in this clinical research study because they have stage IIIB, IIIC or IIID cutaneous (or unknown primary) melanoma with lymph node disease and have yet to undergo surgery. There are two phases, Prime Phase and a Boost Phase. If they participate they will receive nivolumab in combination with CMP-001 for a total of 7 weeks (Prime Phase) prior to surgery. Surgery will be performed approximately 2-4 weeks after completion of the Prime Phase. After recovery from surgery patients will receive additional nivolumab in combination with CMP-001 for approximately 46 additional weeks (Boost Phase).
The main goal of this research study to determine if the combination of nivolumab and CMP-001 improves the likelihood of eradicating (destroying) disease in the lymph node (pathologic response rate). Pathologic responses are associated with improved relapse-free and overall survival in melanoma.
Prior to surgery (Prime Phase) Nivolumab 240mg, will be administered as a 30-minute IV infusion on an outpatient basis. During the Prime Phase, 3 cycles of Nivolumab will be administered every 2 weeks over a 6 week period starting with cycle 2, cycle 4 and then cycle 6.
Prior to surgery (Prime Phase) CMP-001 will be given as an injection from a syringe weekly for a total of 7 weeks. The first injection (week 1), 5mg, will be applied directly into the skin and the remaining injections, 10mg will be administered, will be given intra-tumorally for weeks 2-7.
Surgery will be performed to the cancerous lymph node 2-4 weeks after the Prime Phase is completed.
After recovery from surgery (Boost Phase) Nivolumab will be administered at 240mg every 2 weeks or 480 mg every 4 weeks depending on the physician's preference. CMP-001, 5mg, will be administered by injections intra-tumorally every 4 weeks for up to 54 weeks.
Patients will be followed to assess for survival status until death, withdrawal of consent, or the end of the study, whichever occurs first. This will be done every 3 months.

Experimental: Nivolumab and CMP-001 Combination
Prime Phase -Nivolumab 240mg, IV Infusion, every two weeks starting with Cycle 2 ( Cycles 2, 4, 6) for 6 weeks in combination with CMP-001, 5mg, Injection, at Week 1 and the remaining injections, 10 mg will be administered Weeks 2 -7.
Boost Phase -Nivolumab 240mg, IV Infusion, every two weeks, over a 46 week period in combination with CMP-001, 5mg, administered every 4 weeks for 1 year.
A molecule comprised of a 30 nucleotide strand, flanked by 10 guanines on either end. The nucleotide strand is surrounded by a Qβ viral-like protein. The intended mechanism of action of CMP-001 in oncology is the activation of TLR9 in pDC within the tumor or the tumor-draining lymph nodes (tumor-associated pDC).
A fully human Ig G4 antibody that blocks PD-1. Nivolumab was initially approved by the FDA for the treatment of patients with unresectable or metastatic melanoma and disease progression following ipilimumab and, if BRAF V600 mutation positive, a BRAF inhibitor. Nivolumab has also been FDA approved to treat patients with advanced (metastatic) squamous non-small cell lung cancer (NSCLC) with progression on or after platinum-based chemotherapy, as well as advanced renal cell carcinoma.
- Major Pathologic Response Rate (MPR) [ Time Frame: Every 6 weeks from start of study treatment, up to 52 weeks ]A ratio of responders (to treatment) to total number of tumors (responders plus non-responders to treatment).
- Relapse-Free Survival (RFS) [ Time Frame: 3 years ]The length of time from the initiation of treatment that patients survive without recurrence of disease.
- Overall Survival (OS) [ Time Frame: 3 years ]The length of time from the start of treatment that patients remain alive.
- Expression of inhibitory and activating receptors and ligands [ Time Frame: 3 years ]Circulating and intra-tumoral immune cells, including T-cells (CD8, CD4, Tregs) and antigen-presenting cells (monocytes, macrophages, MDSCs), will be compared pre and post nivolumab and CMP-001 combination treatment.
- TCR clonality/diversity analyses of circulating and intra-tumoral CD8+ T-cells [ Time Frame: 3 years ]TCR clonality/diversity will be compared pre and post nivolumab and CMP-001 combination treatment.
- Genetic and transcriptomic signatures of response/non-response [ Time Frame: 3 years ]Genetic and transcriptomic signatures will be compared between patients who do and do not respond to study treatment.
- Novel tumor imaging characteristics in responders and non-responders [ Time Frame: 3 years ]Tumor imaging characteristics will be compared between patients who do and do not respond to study treatment.
