Melanoma Research

Melanoma Research in the CoE is Directed by Dr. Keiran Smalley, a cancer biologist with extensive experience in developing new melanoma treatment strategies that have been translated into the clinic. Dr. Smalley currently serves on the Steering Committees of the Society for Melanoma Research, the Scientific Advisory Board of the Melanoma Research Foundation and is a Standing Member of the National Cancer Institutes Molecular Cancer Therapeutics Study Section.

Melanoma research at Moffitt takes place both within individual labs and through four collaborative working groups that focus on specific areas in melanoma research.

The areas of focus for individual researchers includes mechanisms of melanoma development, identification of driver oncogenes and signaling pathways involved in melanomagenesis, the role of the immune system and functional studies on the development of melanoma metastases. This knowledge is then leveraged to develop novel targeted therapy and immunotherapy approaches that help inform the clinical trials being undertaken by our colleagues in the Department of Cutaneous Oncology. 

Melanoma Working Groups

 

Brain metastases

Melanoma MetastasesThe development of brain metastases is one of the deadliest complications of advanced melanoma. Both targeted therapies and immunotherapies are less effective against brain metastases than melanomas that grow at other organ sites. CoE members are providing national leadership in melanoma brain metastasis research and have innovative new clinical trials open for patients with both brain metastases and leptomeningeal melanoma metastases. In February of 2018, the CoE hosted the second Melanoma Research Foundation Brain Metastases Workshop in Tampa. This meeting gathered over 40 experts from around the U.S. to discuss the latest basic and clinical research on melanoma brain metastases. A number of key recommendations were made and led to the development of a white paper that was published in 2019. The brain metastasis working group (Drs. Forsyth, Liu, Duckett, Abate-Daga, Rix, Chen, Karreth, Macaulay, Smalley, Kanetsky) meets monthly and is addressing some of the key questions that face the field including; how do melanoma cells metastasize to the brain and do we need to develop specific therapies for melanoma brain metastases? Funding for the brain metastasis work is provide by the National Cancer Institute, the Department of Defense and the State of Florida.

Acral melanoma

Acral melanoma is a rare subtype melanoma that occurs primarily on the hands and feet. It is the most common form of melanoma in patients of Asian and African-American origin. At this time little is known about acral melanoma biology and there are few effective treatments. A new CoE working group (Drs. Messina, Smalley, Karreth, Chen, Teer, Koomen, McLeod) aims to identify the genetic drivers of acral melanoma development and to develop new animal models and ultimately therapies for this disease. The work is funded by a three year grant from the Melanoma Research Alliance.

Uveal melanoma

Uveal melanoma is the most common cancer of the eye. It is somewhat unique from skin melanoma in having a very low mutational burden and a near total resistance to both targeted therapy and immunotherapy. The CoE has two active groups working on uveal melanoma. The first is led by Drs. David Morse and Nikhil Khushalani and is focused on the development of new radiochemicals to target metastatic uveal melanoma. This is funded by a three-year grant from the Melanoma Research Alliance and by an SBIR grant from the NIH. The second group focuses upon epigenetic deregulation in uveal melanoma and constitutes a multi-institutional collaboration between Moffitt (Drs. Smalley/Karreth), University of Miami (Dr. Bill Harbour) and the University of Florida (Dr. Jonathan Licht). This work is funded by a Bankhead-Coley award from the State of Florida.

Pediatric melanoma

Although most commonly considered to be an adult disease, melanoma can also occur in pediatric patients. The incidence of pediatric melanoma is rising, particularly in individuals between the ages of 15-19. The majority of pediatric melanomas are sporadic and relatively little is known about their molecular basis. This working group leverages Moffitt’s unique clinical experience (Drs. Sondak, Messina) along with cutting edge research methods (Drs. Adeegbe, Karreth, Tsai, Smalley, Chen) to delineate the mechanisms of pediatric melanoma development. This work is funded by a pilot grant from the V Foundation and a Live Like Bella Grant from the State of Florida.
