Impact of venetoclax monotherapy on the quality of life of patients with relapsed or refractory chronic lymphocytic leukemia: results from the phase 3b VENICE II trial.

Venetoclax, a potent B-cell lymphoma-2 (BCL-2) inhibitor, has demonstrated clinical efficacy in chronic lymphocytic leukemia (CLL). VENICE II is an open-label, single-arm, phase 3b study (NCT02980731) evaluating the impact of venetoclax monotherapy (400 mg once daily) for ≤2 years on health-related quality of life (HRQoL) of patients with relapsed/refractory CLL. The primary endpoint was mean change in the global health status (GHS)/quality of life (QoL) subscale of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30) from baseline to Week 48. Overall, 210 patients received ≥1 dose of venetoclax; median treatment duration was 67.4 weeks. The primary endpoint was met with mean improvement of +9.3 points (n = 156, 95% confidence interval 6.1-12.5; p=.004) in GHS/QoL. At Week 48, clinically meaningful improvements were observed for role functioning, fatigue, and insomnia domains of EORTC QLQ-C30, suggesting venetoclax monotherapy has a positive impact on HRQoL. No new safety signals were reported.

Budget Impact of 12-Month Fixed Treatment Duration Venetoclax in Combination with Obinutuzumab in Previously Untreated Chronic Lymphocytic Leukemia Patients in the United States.

OBJECTIVES: This study aimed to assess the total cost of care (TCC) and budget impact of introducing 12-month fixed duration venetoclax + obinutuzumab (VEN+G) as first-line treatment for chronic lymphocytic leukemia (CLL) from the perspective of a US health plan with 1,000,000 (1M) members. METHODS: The 3-year model included the following comparators: fludarabine + cyclophosphamide + rituximab (FCR), bendamustine + rituximab (BR), obinutuzumab + chlorambucil (GClb), ibrutinib (Ibr), and Ibr+Rituximab/obinutuzumab [Ibr+R/Ibr+G]). TCC included US-specific costs associated with treatment (i.e., drug, administration, and wastage), adverse events, routine care, and monitoring. Dosing and safety data were drawn from clinical trials and US package inserts. Budget impact outcomes were presented on an absolute and per-member per-month (PMPM) basis. Sensitivity analyses explored uncertainty in influential parameters, including scenarios testing the duration of treat-to-progression agents. RESULTS: Over the 3-year time horizon, introducing VEN+G in a 1M-member health plan resulted in total cost savings of $1,550,663 (PMPM - $0.04), compared to a scenario without VEN+G. The fixed 12-month duration of VEN+G contributed to this cost saving by reducing cumulative treatment costs compared with Ibr-based regimens. By year 3, the cumulative difference in TCC of VEN+G compared with Ibr, Ibr+G, and Ibr+R amounted to - $300,942, - $367,001, and - $369,784, respectively. Extensive sensitivity analyses supported the base case findings. CONCLUSIONS: Introducing VEN+G among first-line CLL treatments to a US health plan resulted in cost savings compared to a plan with chemoimmunotherapies and Ibr-based therapies only. Economic benefits of VEN+G, a novel agent with fixed treatment duration, coupled with proven clinical benefits should help inform formulary adoption decisions and treatment recommendations.

The Social Value of Improvement in Activities of Daily Living among the Advanced Parkinson's Disease Population.

OBJECTIVES: Quantify the value of functional status (FS) improvements consistent in magnitude with improvements due to levodopa-carbidopa intestinal gel (LCIG) treatment, among the advanced Parkinson's disease (APD) population. METHODS: The Health Economic Medical Innovation Simulation (THEMIS), a microsimulation that estimates future health conditions and medical spending, was used to quantify the health and cost burden of disability among the APD population, and the value of quality-adjusted life-years gained from FS improvement due to LCIG treatment compared to standard of care (SoC). A US-representative Parkinson's disease (PD)-comparable cohort was constructed in THEMIS based on observed PD patient characteristics in a nationally representative dataset. APD was defined from the literature and clinical expert input. The PD and APD cohorts were followed from 2010 over their remaining lifetimes. All individuals were ages 65 and over at the start of the simulation. To estimate the value of FS improvement due to LCIG treatment, decreases in activities of daily living (ADL) limitations caused by LCIG treatment were calculated using data from a randomized, controlled, double-blind, double-dummy clinical trial and applied to the APD population in THEMIS. RESULTS: Total burden of disability associated with APD was $17.7 billion (B). From clinical trial data, LCIG treatment versus SoC lowers the odds of difficulties in walking, dressing, and bathing by 76%, 42% and 39%, respectively. Among the APD population, these reductions generated $2.6B in value to patients and cost savings to payers. The added value was 15% of the burden of disability associated with APD and offsets 15% of the cost of LCIG treatment. CONCLUSIONS: FS improvements, consistent with improvements due to LCIG treatment, in the APD population created health benefits and reduced healthcare costs in the US.

The effect of functional status impairment on nursing home admission risk among patients with advanced Parkinson's disease.

Aims: To estimate the relationship between functional status (FS) impairment and nursing home admission (NHA) risk in Parkinson's disease (PD) patients, and quantify the effect of advanced PD (APD) treatment on NHA risk relative to standard of care (SoC).Materials and methods: PD patients were identified in the Medicare Current Beneficiary Survey (MCBS) (1992-2010). A working definition based on the literature and clinical expert input determined APD status. A logit model estimated the relationship between FS impairment and NHA risk. The effect of levodopa-carbidopa intestinal gel (LCIG) on NHA risk relative to SoC was simulated using clinical trial data (control: optimized oral levodopa-carbidopa IR, ClinicalTrials.gov NCT00660387 and NCT0357994).Results: Non-advanced PD and APD significantly increased NHA risk when controlling for demographics (p < 0.01). APD status was no longer significant after controlling for FS limitations, implying that FS limitations explain the increased NHA risk in APD patients. Reduced impairment in FS in patients with APD treated with LCIG reduced risk of NHA by 13.5% relative to SoC.Limitations: This study applies clinical trial results to real-world data. LCIG treatment might have a different effect on NHA risk for the nationally representative population than the effect measured in the trial. Both data sources employ different instruments to measure FS, instrument wording and study follow-up differed, which might bias our estimates. Finally, there lacks consensus on a definition of APD. The prevalence of APD in this study is high, perhaps due to the specific definition used.Conclusions: Patients with APD experience a higher risk in NHA than those with non-advanced disease. This increased risk in NHA in patients with APD is explained by greater limitations in FS. The relative reduction in risk of NHA for the APD population treated with LCIG is quantitatively similar to doubling Medicaid home care services.

Developing consensus among movement disorder specialists on clinical indicators for identification and management of advanced Parkinson's disease: a multi-country Delphi-panel approach.

BACKGROUND: Lack of a global consensus on the definition of advanced Parkinson's disease (APD) and considerations for timing of device-aided therapies may result in heterogeneity in care. OBJECTIVES: To reach consensus among movement disorder specialists regarding key patient characteristics indicating transition to APD and guiding appropriate use of device-aided therapies in the management of PD symptoms. METHODS: A Delphi-panel approach was utilized to synthesize opinions of movement disorder specialists and build consensus. RESULTS: A panel was comprised of movement disorder specialists from 10 European countries with extensive experience of treating PD patients (mean =24.8 ± 7.2 years). Consensus on indicators of suspected APD and eligibility for device-aided therapies were based on motor symptoms, non-motor symptoms, and functional impairments. Key indicators of APD included: (i) motor-moderate troublesome motor fluctuations, ≥1 h of troublesome dyskinesia/day, ≥2 h "off" symptoms/day, and ≥5-times oral levodopa doses/day; (ii) non-motor-mild dementia, and non-transitory troublesome hallucinations; (iii) functional impairment-repeated falls despite optimal treatment, and difficulty with activities of daily living. Patients with good levodopa response, good cognition, and <70 years of age were deemed as good candidates for all three device-aided therapies. Patients with troublesome dyskinesia were considered good candidates for both levodopa-carbidopa intestinal gel and Deep Brain Stimulation (DBS). PD patients with levodopa-resistant tremor were considered good candidates for DBS. CONCLUSION: Identifying patients progressing to APD and suitable for device-aided therapies will enable general neurologists to assess the need for referral to movement disorder specialists and improve the quality of care and patient outcomes.

Assessment of treatment and monitoring patterns and subsequent outcomes among patients with chronic myeloid leukemia treated with imatinib in a community setting.

INTRODUCTION: Real-world treatment and monitoring patterns have not been well documented among imatinib-treated chronic phase chronic myeloid leukemia (CP-CML) patients. Thus, we evaluated these patterns and responses to imatinib in CP-CML patients. METHODS: This retrospective study, based on the Georgia Cancer Specialists' electronic medical record (EMR) system, identified CP-CML patients initiating treatment with imatinib from 01/01/2002 to 11/01/2011 who were subsequently followed for ≥6 months. RESULTS: A total of 177 patients met the study criteria. Imatinib dose modification occurred in 59 patients (33%). Rates of treatment interruption, discontinuation, and switching to another therapy were 16%, 24%, and 23%, respectively. Of 27 patients discontinuing imatinib for lack of efficacy, 9 (33%) had initial dose escalation; 26 patients (96%) eventually switched to a second-generation tyrosine kinase inhibitor. By 3 months, 168 patients remained on imatinib, of whom 96 (57%) had undergone cytogenetic and/or molecular testing. The frequency of response monitoring fluctuated over time, with rates as high as 28% for cytogenetic and 69% for molecular testing. Cumulative response rates steadily increased; 18 month rates were 47% for complete cytogenetic response and 26% for major or complete molecular response. There were no cases of progression and/or death among 38 patients who were regularly monitored for molecular response within the first 12 months of imatinib. Ten of 98 patients (10%) not regularly monitored had progressed or died. CONCLUSIONS: Almost one-third of patients initiating imatinib for CP-CML required dose modification, treatment interruption, or discontinuation. Opportunities for improved monitoring in this setting were identified. Limitations include those inherent to retrospective analyses based on EMR and the uncertain extrapolability of the results.

Modeling causes of aggressive behavior in patients with dementia.

PURPOSE OF THE STUDY: To examine factors predicting development of aggression in patients with dementia as a step toward developing preventive strategies and nonpharmacologic therapies. DESIGN AND METHODS: Study participants were 171 nonaggressive, community-residing VA patients aged more than 60, newly diagnosed with dementia. Patients and caregivers were assessed at baseline and at months 5, 9, 13, 17, 21, and 25. Aggression was evaluated using the Cohen-Mansfield Agitation Inventory. Survival models incorporating direct and indirect effects were conducted to estimate associations between psychosocial factors (baseline and change measures of dementia severity, pain, depression, caregiver burden, patient-caregiver relationship, and nonaggressive physical agitation) and time to aggression onset. RESULTS: Higher levels of baseline caregiver burden, worst pain, declining patient-caregiver relationship, and increasing nonaggressive physical agitation predicted increased risk of aggression. Baseline dementia severity and depression were indirectly related to onset of aggression. The association between increasing nonaggressive physical agitation and time to aggression onset was independent of the associations between our psychosocial measures and time to aggression onset. IMPLICATIONS: Potentially mutable factors were associated with development of aggression. The longitudinal design of this study and its sample of newly diagnosed, previously nonaggressive dementia patients strengthen prior findings in the literature.

Clinical and economic outcomes associated with adjuvant chemotherapy in elderly patients with early stage operable breast cancer.

OBJECTIVES: Breast cancer poses a huge medical burden to the U.S. health-care system, and chemotherapy is an important contributor to cancer costs. This article examines the differences between breast cancer patients who received chemotherapy and those who did not in costs and survival by age, treatment, and axillary node status. METHODS: We studied a cohort of 23,110 node-positive and 31,572 node-negative women aged 65 years and older diagnosed with incident American Joint Committee on Cancer stage I, II, or IIIA breast cancer between January 1, 1991, and December 31, 2002, using Surveillance Epidemiology and End Results-Medicare data. Total treatment costs and costs associated with the use of chemotherapy were estimated by using the phase-of-care approach. The phase-specific costs were combined to estimate total Medicare payments for cancer care from diagnosis to death. Cox proportional hazard ratio of mortality was used to determine the effectiveness of adjuvant chemotherapy after adjusting for selected patient and tumor characteristics. We used propensity scores to minimize the bias associated with the receipt of adjuvant chemotherapy. RESULTS: Regression-adjusted difference in the average lifetime cost estimates for all node-positive patients receiving chemotherapy was approximately $2438 and was significantly higher (P < 0.05) than for patients not receiving chemotherapy. Mortality was significantly lower in node-positive and node-negative women aged 65 to 74 years receiving chemotherapy. CONCLUSIONS: Decision makers can use cost and effectiveness estimates from this study to assess the relative value of chemotherapy in different age groups.

Costs and cost-effectiveness of a telemedicine intensive care unit program in 6 intensive care units in a large health care system.

PURPOSE: The purpose of this study is to estimate the costs and cost-effectiveness of a telemedicine intensive care unit (ICU) (tele-ICU) program. MATERIALS AND METHODS: We used an observational study with ICU patients cared for during the pre-tele-ICU period and ICU patients cared for during the post-tele-ICU period in 6 ICUs at 5 hospitals that are part of a large nonprofit health care system in the Gulf Coast region. We obtained data on a sample of 4142 ICU patients: 2034 in the pre-tele-ICU period and 2108 in the post-tele-ICU period. Economic outcomes were hospital costs, ICU costs and floor costs, measured for average daily costs, costs per case, and costs per patient. RESULTS: After the implementation of the tele-ICU, the hospital daily cost increased from $4302 to $5340 (24%); the hospital cost per case, from $21,967 to $31,318 (43%); and the cost per patient, from $20,231 to $25,846 (28%). Although the tele-ICU intervention was not cost-effective in patients with Simplified Acute Physiology Score II 50 or less, it was cost-effective in the sickest patients with Simplified Acute Physiology Score II more than 50 (17% of patients) because it decreased hospital mortality without increasing costs significantly. CONCLUSIONS: Hospital administrators may conclude that a tele-ICU program aimed at the sickest patients is cost-effective.
