ClonoSEQ Testing for Minimal Residual Disease in Multiple Myeloma: Cleveland VA Experience And Cost Analysis
BACKGROUND
Minimal residual disease (MRD) testing in myeloma has been shown to be a strong prognostic marker for progression-free and overall survival. Limited data suggest MRD results may also be useful for therapy discontinuation decisions. The clonoSEQ Assay utilizes next generation sequencing involving a bone marrow sample, obtained at the time of diagnosis, to identify patient-specific sequence(s).
DISCUSSION
The same methodology is then applied later to assess for MRD. Although widely adopted at most US academic centers, there has been limited use of MRD across VA centers. In 2022 the Cleveland Louis Stokes VAMC partnered with Adaptive Biotechnologies to develop a process for MRD/clonoSEQ testing in myeloma pts. Hematology, Pathology, Medicine, Administration and Adaptive Biotechnologies representatives met to develop a streamlined process for ordering, sample procurement, billing and result documentation. In 5/2022 the 1st specimen was sent. EQUATE is a national cooperative group trial requiring baseline clono- SEQ testing with a positive sequence ID. Daratumumab hyaluronidase (part of standard treatment) is provided to the institution at no cost on the trial but otherwise would cost the VA $5,797.38/dose. clonoSEQ costs VA $1950/test. There have been 14 specimens sent involving 12 pts: 12 baseline marrow and 2 for MRD (posttransplant). All of the baseline specimens were found to have an identifiable sequence. Both of the MRD tracking specimens were positive. The average turnaround time for clonoSEQ results was 13.2 days (range 7 to 18 days). 4 of the 12 pts with a positive initial clonoSEQ ID qualified for the EQUATE trial but would not have been deemed eligible without the baseline clonoSEQ results. 2 of these pts have enrolled on the trial and started treatment. Costs for 14 clonoSEQ tests: $27,300. Estimated cost savings for the 2 pts enrolled onto EQUATE: $127, 542.36/pt/year= $255,084.72/year. Overall cost savings: $227,784.72.
CONCLUSIONS
An efficient process for baseline and post-treatment (MRD) clonoSEQ testing in myeloma pts was developed. Although expensive, use of this test resulted in significant overall cost savings by allowing enrollment onto a clinical trial. In addition, if studies determine that negative MRD results can guide therapeutic decisions, use of clonoSEQ testing may result in further benefits.
