Precipio launches promising assay for hematologic cancers

Specialty cancer diagnostics company Precipio Inc. launches HemeScreen, a novel proprietary test for mutations in hematologic cancers that shows significant promise. They are the first to offer a low cost, rapid molecular screening panel for hematologic mutations. The test screens for four key genes critical to determining a patient’s treatment plan, with an estimated 150,000 tests conducted per year in the US.

HemeScreen will be offered in two forms:

  1. CLIA test: Offered in Precipio’s laboratory in New Haven, CT.
  2. Reagents: A set of RUO reagents sold to other reference labs to perform the test in their CLIA laboratories.

Screening tools allow laboratories to quickly and inexpensively rule out negative patient samples for mutations in critical cancer genes, eliminating the need to perform more complex, costly genetic testing with longer turnaround times for those patients.

Precipio’s new HemeScreen assay delivers results within hours (vs. industry TAT of 7-10 days), at a portion of the cost of currently used genotyping technologies such as DNA sequencing and Taqman SNP genotyping.

The assay tests for mutations in the CALR, JAK2, JAK2 exon 12, and MPL genes. These genes are vitally important to developing the clinical roadmap for the patient. However, the majority of patients do not present any of these mutations, with less than 20% of patient samples returning a positive result. For these markers, if the result is negative, no additional testing is required, and results are reported immediately. If the assay identifies a mutation, the lab reverts to the original process, with additional testing via NGS or Taqman SNP genotyping to identify the specific mutation within that gene.

 

Key Benefits

The low cost of this testing is the top benefit. The current cost of test reagents for all four genes in a CLIA laboratory is approximately $300, and these tests are typically reimbursed at around $600. Precipio’s HemeScreen assay will cost around $100 to run, which is less than 33% of the cost of the four genes combined.

Furthermore, as these genes are mutually exclusive, they are typically tested in a reflex manner (meaning the first gene is tested, if positive the testing stops, if negative it continues to the next one etc.). This is both costly and time consuming, with laboratories typically taking 7-10 days to report results for these tests. Precipio’s HemeScreen will enable reporting of negative results (80% of cases) within approximately 4-6 hours, enabling a same-day total turnaround time.

 

Clinical Impact

The genes screened are relevant to the patient’s diagnostic assessment and they may impact treatment for patients with myeloproliferative and myelodysplastic (MDS) malignancies or cancers. In the US there are approximately 300,000 patients with these diseases, with about 40,000 new patients diagnosed each year. The NCCN guidelines require that every patient diagnosed with one of these cancers be tested for the genes offered in Precipio’s HemeScreen panel. Identifying a positive mutation for a patient means they can be accurately diagnosed with the specific neoplasm, as well as placed on the appropriate therapy, some of which are targeted. For example, patients with a JAK2 mutation are placed on a JAK2 inhibitor such as Jakafi, which can be critical to the patient’s successful battle with their disease.

Currently, few laboratories offer these tests because they are costly, and require substantial volume to be run cost-effectively. Even larger laboratories typically hold specimens received and batch them in copious quantities, resulting in the patients typically waiting 7-10 additional days for the results of these tests, in order to receive their final diagnosis.

Given that 80% of these test results are negative, a cost-effective screening panel that returns a positive/negative answer within one day, can provide a substantial clinical improvement and deliver a quick answer to the clear majority of patients.

The HemeScreen test utilizes the same HRM (High Resolution Melt) technology applied to ICE COLD-PCR (ICP), Precipio’s mutant enrichment technology for liquid biopsy.

 

Business Opportunity

The annual U.S. market opportunity alone for this area of testing is estimated by Precipio to be approximately $100M. Precipio’s HemeScreen assay can enable cost savings of approximately $200 per sample, or as much as $30 million of cost savings per year for the U.S. clinical testing industry, while also providing a significantly faster service.

Precipio is currently in discussions with several leading laboratories both domestically and internationally, to explore opportunities for this proprietary testing technology.

“Running an expensive and time-consuming test for genes that occur in less than 20% of patients seemed to be a very inefficient process. With our expertise in hematologic malignancies, we decided to develop a hematologic screening application, creating a simpler and more cost-effective approach, which would reduce the cost and turnaround time for most of those tests,” comments Ilan Danieli, CEO. “The HemeScreen assay further substantiates us as a market leader in the heme testing field by creating a more efficient testing process. We plan to make the HemeScreen assay commercially available to all labs interested in reducing costs and increasing profitability, while improving the quality of care by providing results in hours vs. days.”

 

This new assay holds a significant amount of promise. The quick turnaround time and cost efficiency are two key factors that can not be overstated. The more effectual the lab, the more time and resources can be spent looking after the patient.
