In Figure 1, significant cost savings occur in the third year largely due to 24 months fixed duraon therapy with venetoclax + R, which has lower total cost of care than other novel agents (i.e., venetoclax monotherapy, ibrunib, and idelalisib + R) that are administered connuously. Figure 1. Total Cost of Care Strafied by Cost Category ABSTRACT BACKGROUND Venetoclax label was recently expanded in the United States (US) to include the use of 24-months fixed duraon venetoclax in combinaon with rituximab (R) in paents with chronic lymphocyc leukemia (CLL), with or without 17p deleon, who have received at least one prior therapy. Our study aims to esmate the 3-year budgetary consequence of the expanded indicaon from the perspecve of a US payer with 1,000,000 members. METHODS The model included venetoclax monotherapy, ibrunib, and idelalisib + R as comparators. Dosing regimen, treatment duraon, and safety data were extracted from package inserts. Total cost of care was esmated for each regimen and included drug costs, wastage, drug administraon, adverse events, monitoring, and roune care. Drug costs were obtained from the Truven Health Analycs Red Book whereas other costs were based on published literature and a MarketScan analysis (Copyright ©2018 Truven Health Analycs LLC. All Rights Reserved). Monitoring costs were applied to venetoclax monotherapy and venetoclax + R for ramp up management and idelalisib + R for liver funcon monitoring and pneumonis. Scenario analyses explored uncertainty in influenal parameters. Outcomes were presented in absolute incremental budget impact and per-member per-month budget impact (PMPM). RESULTS Over the three-year me horizon, the expanded indicaon of venetoclax was associated with total cost savings of $729,507 or an average PMPM of -$0.0200 for a US payer with 1,000,000 members. By Year 3, the cumulave difference in total cost of care of venetoclax + R compared with idelalisib + R and ibrunib is -$107,238, and -$98,518, respecvely. Scenario analyses supported the base case findings. CONCLUSION From a US payer’s perspecve, the expanded indicaon of venetoclax for a 24 month fixed duraon was associated with cost savings of $729,507 in paents with R/R CLL over a three-year period. The 24-month fixed duraon of venetoclax + R was a key driver in reducing total cumulave treatment costs. OBJECTIVE To compare total cost of care of venetoclax + R, venetoclax monotherapy, ibrunib, and idelalisib +R across a 3 year me horizon. To esmate budget impact of the expanded indicaon of venetoclax + R compared to the scenario without the label expansion To compare the total cost of care aributable to tumor lysis syndrome by tumor burden In Figure 2, by Year 3, the cumulave differences in total cost of care of venetoclax + R compared to idelalisib + R, ibrunib, and venetoclax monotherapy are -$107,238, -$98,518, and -$67,942, respecvely. Figure 2. Cumulave Total Cost of Care Over the 3-Year Time Horizon Figure 3. % of Total Cost of Care Aributable to Monitoring for TLS at Month 1, Year 1, Over 3 Years Strafied by Tumor Burden Low tumor burden: Nodal mass ≤ 5 cm and ALC < 25,000; Medium tumor burden: Nodal mass ≥ 5 cm to < 10 cm or ALC ≥ 25,000; High tumor burden: Nodal mass ≥ 10 cm or nodal mass ≥ 5 cm and ALC ≥ 25,000. *ALC: absolute lymphocyte count. During venetoclax ramp-up, the total cost of care is higher among high tumor burden paents due to monitoring costs for tumor lysis syndrome (High: $17,350 Medium: $6,789 Low: $2,154). However, the total cost of care becomes comparable across three tumor burden categories because the cost of managing TLS accounts for relavely small fracon of the total cost of care. Table 2.

ABSTRACT BACKGROUND Venetoclax label was recently expanded in the United States (US) to include the use of 24-months fixed duration venetoclax in combination with rituximab (R) in patients with chronic lymphocytic leukemia (CLL), with or without 17p deletion, who have received at least one prior therapy. Our study aims to estimate the 3-year budgetary consequence of the expanded indication from the perspective of a US payer with 1,000,000 members.
METHODS The model included venetoclax monotherapy, ibrutinib, and idelalisib + R as comparators. Dosing regimen, treatment duration, and safety data were extracted from package inserts. Total cost of care was estimated for each regimen and included drug costs, wastage, drug administration, adverse events, monitoring, and routine care. Drug costs were obtained from the Truven Health Analytics Red Book whereas other costs were based on published literature and a MarketScan analysis (Copyright ©2018 Truven Health Analytics LLC. All Rights Reserved). Monitoring costs were applied to venetoclax monotherapy and venetoclax + R for ramp up management and idelalisib + R for liver function monitoring and pneumonitis. Scenario analyses explored uncertainty in influential parameters. Outcomes were presented in absolute incremental budget impact and per-member per-month budget impact (PMPM).
RESULTS Over the three-year time horizon, the expanded indication of venetoclax was associated with total cost savings of $729,507 or an average PMPM of -$0.0200 for a US payer with 1,000,000 members. By Year 3, the cumulative difference in total cost of care of venetoclax + R compared with idelalisib + R and ibrutinib is -$107,238, and -$98,518, respectively. Scenario analyses supported the base case findings.
CONCLUSION From a US payer’s perspective, the expanded indication of venetoclax for a 24 month fixed duration was associated with cost savings of $729,507 in patients with R/R CLL over a three-year period. The 24-month fixed duration of venetoclax + R was a key driver in reducing total cumulative treatment costs.
OBJECTIVE • To compare total cost of care of venetoclax + R, venetoclax monotherapy,
ibrutinib, and idelalisib +R across a 3 year time horizon. • To estimate budget impact of the expanded indication of venetoclax + R
compared to the scenario without the label expansion • To compare the total cost of care attributable to tumor lysis syndrome by
tumor burden
• In Figure 2, by Year 3, the cumulative differences in total cost of care of venetoclax + R compared to idelalisib + R, ibrutinib, and venetoclax monotherapy are -$107,238, -$98,518, and -$67,942, respectively.

• During venetoclax ramp-up, the total cost of care is higher among high tumor burden patients due to monitoring costs for tumor lysis syndrome (High: $17,350 Medium: $6,789 Low: $2,154).

* For Year 2, total costs of care include treatment cost and routine costs of care; Drug cost are: Venetoclax +/- R ($135,293), Ibrutinib ($147,783), Idelalisib + R ($123,961).
** In Year 3, the treatment cost ($13,009) for Venetoclax + R is for the 24th cycle following the first month of ramp up in Year 1.
