How the Dutch resume elective surgery in melanoma after COVID delays
ROTTERDAM, Netherlands and SAN DIEGO, August 26, 2020, /PRNewswire-AsiaNet/--

SkylineDx signed a collaboration agreement with a multi-disciplinary clinical 
consortium in the Netherlands that designed a trial to implement a diagnostic 
innovation to manage continuity of care delivery when resources are under 
pressure due to COVID. The diagnostic tool, Merlin Assay, identifies melanoma 
(skin cancer) patients for whom postponing sentinel lymph node biopsy (SLNB) 
surgery would be at minimal risk, allowing physicians to better triage care and 
allocate resources. Around 80% of melanoma patients that undergo an SLNB 
surgery to check for metastases, have no detectable disease spread, making the 
surgery redundant. The Merlin Assay uses characteristics from the primary tumor 
and the patient's age to calculate if a patient's risk of having metastases is 
so low that the surgery can be safely avoided. Reducing up to 42% of these 
surgeries [https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7220172/ ]

ph-Node-Metastasis-in-Primary-Cutaneous-Melanoma  ] , the Merlin Assay enables 
hospitals to efficiently direct their surgical resources to patients with the 
highest need, and in case of metastases, prioritize immediate steps on their 
care path. The consortium consists of 8 Dutch institutes and is led by the 
Erasmus MC, University Medical Center Rotterdam (EMC). 

"Reducing the backlog of regular care and maintaining it, is of utmost 
importance while we are preparing for a possible new COVID peak", comments 
Prof. Dr. Kees Verhoef, Head of Oncology – and Gastrointestinal Surgery at EMC. 
"Tools that better direct the use of healthcare resources, will make us better 
equipped to provide adequate cancer care for individual patients at the moment 
they need it". 
A recent US case study from the Mayo Clinic described the clinical pathway of a 
melanoma patient that was referred for the SLNB surgery. It took 21 days of 
extensive use of hospital resources, medical specialists and laboratory tests, 
including a 90-minute surgery under general anesthetics, to arrive at an SLNB 
result which turned out to be negative for metastasis.  For the same patient, 
the Merlin Assay, correctly identified the low risk nature of the patient's 
melanoma after just a few days 
[https://mcpiqojournal.org/article/S2542-4548(20)30101-6/pdf ]. It is an 
illustrative example of how the diagnostic innovation could impact the patient 
pathway. The Dutch trial will capture this information in real world setting.

"Better allocation of resources and a faster turnaround time are not the only 
benefits, using the Merlin Assay in routine clinical practice," continues Dr. 
Dirk Grunhagen, Oncological Surgeon at EMC. "The overall complication rate 
associated with the surgery is between 5-10%. The Merlin Assay may save the 
low-risk patient group surgical complications and the subsequent care needed."

"It has been a proud moment to experience how different stakeholders can come 
together and be innovative in designing and implementing solutions when it is 
most needed," comments Dharminder Chahal, CEO of SkylineDx that developed the 
Merlin Assay. "We are very excited that we were able to contribute by 
accelerating the access to our diagnostic innovation. With the start of this 
study, another important step towards personalizing cancer treatment has been 
taken." 

About Merlin

The Merlin assay uses the CP-GEP model, a powerful algorithm that calculates 
the risk of metastasis in a patient's sentinel lymph nodes. 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. The model has been previously published in JCO Precision Oncology 
[https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7220172/ ] and validated by the 
Erasmus MC, University Medical Center Rotterdam

-a-Clinicopathological-and-Gene-Expression-Profile-CP-GEP-Model-for-Sentinel-Lym
ph-Node-Metastasis-in-Primary-Cutaneous-Melanoma ]. 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 [https://falconprogram.com/ ]. 

About SkylineDx 

SkylineDx [https://skylinedx.com/ ] is a biotechnology company, mainly focused 
on research & development of molecular diagnostics in oncology. The company is 
headquartered in Rotterdam (the Netherlands) and complemented with a field 
medical and scientific affairs team in the US and a CAP/CLIA certified 
laboratory in San Diego (California). SkylineDx uses its expertise to bridge 
the gap between academically discovered gene expression signatures and 
commercially available diagnostic products with high clinical utility, 
assisting healthcare professionals in accurately determining the type or status 
of disease or predict a patient's response to treatment. Based on test results, 
healthcare professionals can tailor the treatment approach to the individual 
patient.
