e18911 Background: Stool-based colorectal cancer (CRC) screening with the multi-target stool DNA (mt-sDNA) test is a guideline endorsed strategy for average-risk individuals age ≥45 years and provides a reference for value-based pricing (VBP); maximum price at which a willingness-to-pay threshold is reached. Blood-based tests (BT) are an emerging screening option. Using recent reported BT performance data from the ECLIPSE study (Guardant Health, Inc.)1, the potential VBP of BT compared with multi-target stool DNA (mt-sDNA) was analyzed. Methods: Using the validated CRC-AIM model, we simulated a cohort of 2 million average-risk individuals who received screening with BT at 1, 2, or 3-year intervals or triennial mt-sDNA between the ages of 45-75 years. For BT, CRC sensitivity, advanced adenoma sensitivity, and specificity were based on reported clinical trial data (83%, 13%, and 90%, respectively). Adherence assumptions for BT and mt-sDNA screening were modeled at perfect (100%) or real-world mt-sDNA adherence (RWE). Key outcomes were life-years gained (LYG) per 1000 individuals vs no screening, and VBP of BT vs mt-sDNA ($895 vs $508) was assessed at a willingness-to-pay (WTP) threshold of $50,000 per quality-adjusted life-year. Results: The triennial mt-sDNA was more effective and less costly vs BT at all intervals with both perfect and RWE adherence at the current price. Compared with mt-sDNA screening, LYG of screening with BT was lower (320 vs. 241-314) and the VBP should be at most $49 and $11 and no-cost at the 1-, 2-, and 3-year intervals, respectively (Table), when perfect adherence is assumed. With RWE adherence, the LYG with mt-sDNA was 306 compared to 229-284 with BT across all intervals. To be comparable to RWE triennial mt-sDNA screening, the maximum VBP for BT would need to be $13 at the 1-year interval and no cost for 2- and 3-year interval. Conclusions: Compared to annual, biannual, and triennial BT, triennial mt-sDNA was more effective at all intervals and 44% to 102% less costly. The maximum price of BT should not exceed $49 to be considered a cost-effective option compared to mt-sDNA when WTP is 50,000. [Table: see text]

SummaryFactors influencing the morbidity and mortality associated with viremic hepatitis C virus (HCV) infection change over time and place, making it difficult to compare reported estimates. Models were developed for 17 countries (Bahrain, Bulgaria, Cameroon, Colombia, Croatia, Dominican Republic, Ethiopia, Ghana, Hong Kong, Jordan, Kazakhstan, Malaysia, Morocco, Nigeria, Qatar and Taiwan) to quantify and characterize the viremic population as well as forecast the changes in the infected population and the corresponding disease burden from 2015 to 2030. Model inputs were agreed upon through expert consensus, and a standardized methodology was followed to allow for comparison across countries. The viremic prevalence is expected to remain constant or decline in all but four countries (Ethiopia, Ghana, Jordan and Oman); however, HCV‐related morbidity and mortality will increase in all countries except Qatar and Taiwan. In Qatar, the high‐treatment rate will contribute to a reduction in total cases and HCV‐related morbidity by 2030. In the remaining countries, however, the current treatment paradigm will be insufficient to achieve large reductions in HCV‐related morbidity and mortality.

SummaryThe hepatitis C virus (HCV) epidemic was forecasted through 2030 for 17 countries in Africa, Asia, Europe, Latin America and the Middle East, and interventions for achieving the Global Health Sector Strategy on viral hepatitis targets—“WHO Targets” (65% reduction in HCV‐related deaths, 90% reduction in new infections and 90% of infections diagnosed by 2030) were considered. Scaling up treatment and diagnosis rates over time would be required to achieve these targets in all but one country, even with the introduction of high SVR therapies. The scenarios developed to achieve the WHO Targets in all countries studied assumed the implementation of national policies to prevent new infections and to diagnose current infections through screening.
