Costs per patient achieving remission with venetoclax-based combinations in newly diagnosed patients with acute myeloid leukemia ineligible for intensive induction chemotherapy.

BACKGROUND: Venetoclax, in combination with azacitidine, decitabine, or low-dose cytarabine (LDAC), received confirmatory approval in 2020 by the US Food and Drug Administration for the treatment of newly diagnosed acute myeloid leukemia (AML) in patients aged 75 years or older or who are ineligible for intensive induction chemotherapy. The economic value associated with response to venetoclax combinations compared with other treatments for this patient population has not been comprehensively evaluated. OBJECTIVE: To assess the cost per patient achieving remission with venetoclax combination therapies, compared with other therapies for newly diagnosed patients with AML who are ineligible for intensive induction chemotherapy, from a US third-party payer perspective. METHODS: The analysis used treatment effect estimates (ie, complete remission [CR] + CR with incomplete blood count recovery [CRi]) from a network meta-analysis and annual cost estimates from a prior budget impact model. The model considered the total cost of care including the costs of drug and administration, adverse events, hospitalization, disease monitoring, blood transfusions, and subsequent AML management when patients discontinued active treatment. Costs per patient achieving CR + CRi associated with venetoclax + azacitidine, venetoclax + LDAC, azacitidine, decitabine, LDAC, and best supportive care (ie, treatment given with the intent to maximize quality of life without specific antileukemic intent, such as blood transfusion products and antibiotics) were calculated as the annual total cost of care per patient divided by the CR + CRi rate. All costs were adjusted to 2020 US dollars. RESULTS: Venetoclax combination therapies were estimated to have substantially lower costs per patient achieving CR + CRi (venetoclax + azacitidine: $473,960; venetoclax + LDAC: $428,071) than alternative treatments. Azacitidine was estimated to have the the highest cost per patient achieving CR + CRi ($1,197,438), followed by best supportive care ($869,849), LDAC ($689,101), and decitabine ($594,074). A pair-wise matrix of the difference between therapies estimated that both venetoclax + azacitidine and venetoclax + LDAC were associated with significantly lower costs per patient achieving CR + CRi than azacitidine (by $723,477 and $769,367, respectively) and LDAC (by $215,141 and $261,030; all P < 0.05). CONCLUSIONS: From a US third-party payer perspective, venetoclax in combination with azacitidine or LDAC was estimated to be associated with a significantly lower cost per patient achieving CR + CRi than azacitidine or LDAC among newly diagnosed patients with AML ineligible for intensive chemotherapy.

The impact of remission duration on the long-term economic burden of acute myeloid leukemia among patients without hematopoietic stem cell transplant in the United States.

BACKGROUND AND AIMS: Acute myeloid leukemia (AML) prognosis is poor, with sustained remission occurring in <35% of young adults and <15% of older adults. This descriptive study examined the potential benefit of prolonged remission on the economic burden of AML. METHODS: Using the IBM MarketScan Commercial and Medicare Supplemental databases, we identified newly diagnosed patients with AML without hematopoietic stem cell transplantation from January 1, 2012 to December 31, 2018; AML diagnosis was the index date. Patients had 6 months of pre-index eligibility and were followed until the end of continuous eligibility, study data, or death. Active treatment and supportive care cohorts were defined; duration-of-remission subgroups (0 to <3, 3 to <6, 6 to <12, and ≥12 months) were established among active treatment patients with remission. Healthcare service utilization and costs were reported over follow-up and mutually exclusive treatment, remission, and post-relapse periods. RESULTS: This study included 1,558 active treatment and 1,127 supportive care patients who were followed for a median of 232 and 62 days, respectively. Over follow-up, active treatment and supportive care patients incurred mean ± standard deviation all-cause healthcare costs of $55,723 ± $61,994 and $68,596 ± $100,375 per-patient-per-month (PPPM), respectively. Decreasing PPPM costs were observed with increased remission duration (0 to <3 months: $71,823 ± $62,635; 3 to <6 months: $54,262 ± $44,734; 6 to <12 months: $35,287 ± $23,699; and ≥12 months: $15,615 ± $10,560). Although median follow-up varied by up to 5-fold, total costs were largely similar across duration-of-remission subgroups (0 to <3 months: $438,569 ± $332,675; 3 to <6 months: $590,411 ± $598,245; 6 to <12 months: $482,902 ± $369,115; and ≥12 months: $448,867 ± $316,133). CONCLUSIONS: The economic burden of AML is substantial, even among untreated patients. Further, among patients with remission, longer durations in remission are associated with reduced PPPM healthcare costs, suggesting that remission-prolonging treatments could help mitigate healthcare costs.

The Surprise Question and Identification of Palliative Care Needs among Hospitalized Patients with Advanced Hematologic or Solid Malignancies.

BACKGROUND: Little is known about quality of life (QOL), depression, and end-of-life (EOL) outcomes among hospitalized patients with advanced cancer. OBJECTIVE: To assess whether the surprise question identifies inpatients with advanced cancer likely to have unmet palliative care needs. DESIGN: Prospective cohort study and long-term follow-up. SETTING/SUBJECTS: From 2008 to 2010, we enrolled 150 inpatients at Duke University with stage III/IV solid tumors or lymphoma/acute leukemia and whose physician would not be surprised if they died in less than one year. MEASUREMENTS: We assessed QOL (FACT-G), mood (brief CES-D), and EOL outcomes. RESULTS: Mean FACT-G score was quite low (66.9; SD 11). Forty-five patients (30%) had a brief CES-D score of ≥4 indicating a high likelihood of depression. In multivariate analyses, better QOL was associated with less depression (OR 0.91, p < 0.0001), controlling for tumor type, education, and spiritual well-being. Physicians correctly estimated death within one year in 101 (69%) cases, yet only 37 patients (25%) used hospice, and 4 (2.7%) received a palliative care consult; 89 (60.5%) had a do-not-resuscitate order, and 63 (43%) died in the hospital. CONCLUSIONS: The surprise question identifies inpatients with advanced solid or hematologic cancers having poor QOL and frequent depressive symptoms. Although physicians expected death within a year, EOL quality outcomes were poor. Hospitalized patients with advanced cancer may benefit from palliative care interventions to improve mood, QOL, and EOL care, and the surprise question is a practical method to identify those with unmet needs.

Young caregivers in the end-of-life setting: a population-based profile of an emerging group.

PURPOSE: Little is known about young caregivers of people with advanced life-limiting illness. Better understanding of the needs and characteristics of these young caregivers can inform development of palliative care and other support services. METHODS: A population-based analysis of caregivers was performed from piloted questions included in the 2001-2007 face-to-face annual health surveys of 23,706 South Australians on the death of a loved one, caregiving provided, and characteristics of the deceased individual and caregiver. The survey was representative of the population by age, gender, and region of residence. FINDINGS: Most active care was provided by older, close family members, but large numbers of young people (ages 15-29) also provided assistance to individuals with advanced life-limiting illness. They comprised 14.4% of those undertaking "hands-on" care on a daily or intermittent basis, whom we grouped together as active caregivers. Almost as many young males as females participate in active caregiving (men represent 46%); most provide care while being employed, including 38% who work full-time. Over half of those engaged in hands-on care indicated the experience to be worse or much worse than expected, with young people more frequently reporting dissatisfaction thereof. Young caregivers also exhibited an increased perception of the need for assistance with grief. CONCLUSION: Young people can be integral to end-of-life care, and represent a significant cohort of active caregivers with unique needs and experiences. They may have a more negative experience as caregivers, and increased needs for grief counseling services compared to other age cohorts of caregivers.
