The Malignant Melanoma Clinical Research Program at the OSUCCC – James offers patients access to clinical trials evaluating the newest agents and strategies for preventing, detecting, diagnosing and treating melanoma and other skin cancers.
In addition, preclinical, translational studies are under way investigating the fundamental causes of melanoma, which will lead to still newer agents to help prevent the disease and to treat it more effectively after onset.
The Malignant Melanoma Clinical Research Program also benefits from National Cancer Institute (NCI) funding to the OSUCCC – James that supports the cost of conducting phase I and phase II clinical trials and facilitates the movement of promising phase II studies into phase III national trials.
- Developing and evaluating immunotherapy approaches for malignant melanoma
- Developing a vaccine to slow or stop the growth of malignant melanoma
- Evaluating the use of new agents to inhibit growth of malignant melanoma

OSU-13124: A Phase I expansion cohort evaluating the Selective Inhibitor of Nuclear Export (SINE) KPT-330 in patients with unresectable melanoma
PI: Kari Kendra, MD
NCT ID: NCT02120222
This trial studies the side effects of selinexor in treating patients with inoperable melanoma. Targeted therapies such as selinexor might stop the growth of tumor cells by stopping them from dividing.
- Incidence, types and severity of adverse events
- Complete biological response and progression-free survival
- Change in tumor markers by immunohistochemistry
Allelic Imbalance Mapping to Uncover CSCC Susceptibility Alleles (5R03CA173788)
PI: Amanda Toland, PhD
This work has the potential to validate a new method of identifying cancer susceptibility alleles, to characterize novel putative tumor suppressor genes at 11q24, important in cutaneous squamous cell carcinoma (SCC) tumorigenesis and to identify genetic differences at this region that play a role in SCC risk. The findings may lead to better SCC therapeutic targets and risk prevention strategies.
- Understand the mechanisms by which variants at 11q24 contribute to SCC tumorigenesis and risk and evaluate their candidacy for therapeutic or preventive strategies for cutaneous SCC
- Validate allele-specific imbalance as a method to identify genes and susceptibility alleles important in cancer, and their potential to identify new genes important in SCC
Mast Cells and Immunosuppression in Skin Cancer (5R21ES020462)
PI: Traci Wilgus, PhD
Over a million new cases of non-melanoma skin cancer (NMSC) are reported every year in the U.S. People who have received organ transplants are at especially high risk for NMSCs that are aggressive and more likely to spread to distant sites. These studies examine the involvement of mast cells, a cell of the immune system, in skin cancer development. The findings could lead to better ways of preventing and treating skin cancer.
- Examine the importance of mast cells to cyclosporine A-mediated tumor progression (cyclosporine A is an immunosuppressive drug commonly taken by transplant patients)
- Determine direct effects of cyclosporine A on dermal mast cells
- The findings will generate new information about the contribution of mast cells to the development and growth of UV-induced skin tumors, both in a normal setting and in the presence of immunosuppressive drugs
Melanoma Clinical Research Accomplishments
A phase I dose escalation trial showed that high-dose interleukin-2 followed by sorafenib was safe and feasible in patients with metastatic melanoma or renal cell carcinoma. The study assayed biomarkers related to the antitumor effects of IL-2 that might be altered by sorafenib: percentages of natural T-regulatory cells, myeloid-derived suppressor cells, and STAT5 phosphorylation in T cells. Twelve of 18 patients were evaluated for dose-limiting toxicity. None were observed. Three patients showed partial tumor responses. Published in the Journal of Immunotherapy.
A phase I trial explored whether administration of a cytokine could enhance the antitumor effects of a proteasome inhibitor. Studies had shown that bortezomib combined with interferon-α (IFN-α) induced synergistic apoptosis in human melanoma cell lines and prolonged survival in a murine model of melanoma. This phase I, dose-escalation study evaluated the tolerability and the maximum tolerated dose of bortezomib in combination with IFN-α-2b in 16 patients (eight women, eight men; median age 59) with metastatic melanoma. One patient had a partial response and seven had stable disease. Progression-free survival was 2.5 months; overall survival was 10.3 months. Bortezomib administration did not augment the ability of IFN-α to induce phosphorylation of STAT1 in circulating immune cells; however, it did reduce plasma levels of proangiogenic cytokines. The combination of bortezomib and IFN-α can be safely administered to melanoma patients. Published in the Journal of Immunotherapy.
A phase I study of high-dose interleukin-2 with sorafenib in patients with metastatic renal cell carcinoma and melanoma. This dose escalation trial evaluated the safety and feasibility of high-dose interleukin-2 (HD IL-2) followed by sorafenib in patients with metastatic melanoma (MM) and renal cell carcinoma (RCC). It examined biomarkers relevant to the antitumor effects of IL-2 that might be altered by sorafenib, including the percentages of natural T-regulatory cells (Tregs), myeloid-derived suppressor cells (MDSC), and STAT5 phosphorylation (pSTAT5) in T cells. No dose-limiting toxicity was observed in 12 of 18 evaluable patients. Treatment-related toxicity was predictable and did not seem to be additive with this schedule of administration. Three patients showed partial responses. No significant changes in the percentage of circulating Treg and MDSC were observed, and sorafenib did not adversely affect the ability of IL-2 to induce pSTAT5 in T cells. HD IL-2 followed by sorafenib was safe and feasible in patients with MM and RCC. Published in the Journal of Immunotherapy.
Translational Research Accomplishments
miR-21 and miR-155 are associated with mitotic activity and lesion depth of borderline melanocytic lesions. This study explored whether microRNA (miR) expression in borderline melanocytic proliferations would provide a molecular profile that could, along with known prognostic factors, identify lesions with high malignant potential. Analysis of primary cutaneous melanomas revealed an 8.6-fold overexpression of miR-21 and a 7.5-fold overexpression of miR-155 compared with benign naevi. When borderline lesions were categorized by mitotic activity and Breslow thickness, miR-21 was associated with mitotic activity and miR-155 was associated with thickness. Among 14 patients with borderline lesions who underwent sentinel lymph-node biopsy (SLNB), positive biopsies were associated with increased miR-21 and miR-155 in the primary lesion compared with lesions with a negative SLNB. MicroRNA expression profiles can be used to characterize atypical melanocytic lesions. Published in the British Journal of Cancer.
MIF antagonist (CPSI-1306) protects against UVB-induced squamous cell carcinoma. Macrophage migration inhibitory factor (MIF) is a proinflammatory cytokine implicated in cutaneous squamous cell carcinomas (SCC). This study used the small-molecule MIF inhibitor (CPSI-1306) to determine whether MIF inhibition could reduce UVB light-induced inflammation and squamous carcinogenesis. The study, which used hairless mice, suggested that CPSI-1306 could slow the rate of tumor development and decrease tumor burden. Overall, the findings suggest that MIF inhibition is a promising strategy for prevention of the deleterious cutaneous effects of acute and chronic UVB exposure. Published in Molecular Cancer Research
