SkylineDx launches US prospective melanoma trial to validate Merlin Assay

ROTTERDAM, Netherlands and SAN DIEGO, June 10, 2021 /PRNewswire/ -- Today, SkylineDx announced that the first hospitals will start including melanoma patients in a large prospective clinical study in the United States, to validate the Merlin Assay. A total of 10 hospitals are collaborating in this trial, including Moffitt Cancer Center, Mayo Clinic and University of Louisville School of Medicine led by the respective principal investigators [2]. In the coming two years, over 2,000 patients with invasive malignant melanoma (skin cancer) indicated for a sentinel lymph node surgery, will be enrolled and followed during 5 years [2].

The study's primary objective is to determine the Merlin Assay's performance on identifying patients that can safely forgo the invasive sentinel lymph node surgery under general anesthesia. This procedure is crucial to determine if the patient has metastasis, however in >80% of patients no metastasis are found making the surgery unnecessary [4]. First results are anticipated within two years after the first patient has been included. The long-term objective, 3 to 5 years after inclusion, allows to follow the patient over time to monitor if the melanoma recurs [2]. The design of this prospective trial was previously communicated during the melanoma tumor board symposium for registered attendees at the World Congress of Melanoma in March of this year [3].

"Merlin Assay will change patient lives. I am thrilled that so many renowned institutes believe in the strength of this test and want to participate in this trial," comments Dharminder Chahal, CEO SkylineDx. "The 80-85% of patients that go through this surgery unnecessarily, do have a >10% risk of surgery-related complications like bleeding, infection and lymphedema where arms and legs swell because the lymph vessels are unable to adequately drain the lymph fluids. Each patient that Merlin can deselect for this invasive surgery, is a win."

About Merlin Assay

The Merlin Assay uses the CP-GEP model, a powerful algorithm that calculates the risk of metastasis in a patient's sentinel lymph nodes [4]. The model is able to calculate risk on an individual basis through a combination analysis of 8 genes from the patient's primary tumor, the tumor thickness and the patient's age; and has been independently validated in both a US [5] and EU [6] retrospective cohort. Further clinical research and validation studies on the predictive use of the CP-GEP model is the main focus of the Merlin Study Initiative, developed under the wings of the Falcon R&D Program.
