RESUMO
OBJECTIVES: Biosimilars provide an opportunity for a more sustainable and cost-effective treatment for multiple sclerosis (MS). This study evaluated the potential financial impact of implementing a formulary change from reference to biosimilar natalizumab (NTZ) from the US commercial payer perspective. STUDY DESIGN: The budget impact of transitioning to biosimilar NTZ for the treatment of relapsing-remitting MS (RRMS) was estimated over a 3-year time horizon based on real-world dosing. Additional scenario analyses were conducted by varying the price differential of biosimilar NTZ. METHODS: The target population was estimated from a 1-million-member hypothetical commercial health plan. Model inputs were drug acquisition costs and treatment-related and patient coinsurance costs. Budget impact and cost savings per member per year were calculated by assuming a biosimilar uptake of 10% in year 1 to 20% in year 3. RESULTS: Over 3 years, 255 patients were estimated to be treated with high-efficacy disease-modifying therapies for RRMS. The inclusion of biosimilar NTZ onto a formulary would result in cumulative cost savings to payers of $452,611 over 3 years, with mean savings per treated member per year of $1179, $1769, and $2359 in years 1, 2, and 3, respectively. One-way sensitivity analyses indicated that budget impact results were most sensitive to drug acquisition costs of both reference and biosimilar NTZ. CONCLUSION: Adoption of biosimilar NTZ can yield considerable cost savings to US health plans that could result in increased treatment access for patients with RRMS.

BACKGROUND: The biosimilar market is growing rapidly, as evidenced by 41 approvals and 37 launches to date. As adalimumab biosimilars launch in the United States, competition among biosimilar and reference adalimumab will likely increase across multiple reference indications, including rheumatology, dermatology, and gastrointestinal diseases, which may lead to decreased payer costs. OBJECTIVE: To evaluate the costs of adding biosimilar adalimumab to a US commercial plan by exploring various utilization and price differential scenarios. METHODS: A 3-year budget impact model for a US commercial plan of 1 million people was developed to assess switching from reference adalimumab or any self-injectable reference tumor necrosis factor (TNF) inhibitor to biosimilar adalimumab. Pharmacy and medical costs were analyzed through high- and low-conversion scenarios from reference adalimumab and the TNF inhibitor class. Price reductions of 5% to 60% relative to reference adalimumab based on previous biosimilar launches were also explored. Short-term medical costs were evaluated as additional simple and complex office visits, with scenarios of half of switch patients having 1 visit up to all switch patients having 10 visits. RESULTS: In a target population of 1,863 patients, switching from reference adalimumab to biosimilar adalimumab had cumulative cost savings of $5,756,073 with slow conversion (10%-20% over 3 years) and $28,780,365 with fast conversion (50%-100% over 3 years). Similar results were seen when switching from any other self-injectable reference TNF inhibitor. Cost savings more than $1 million were seen with a 10% conversion from reference adalimumab and a 15% price reduction from reference adalimumab. Additional office visit scenarios had a negligible impact on budget, with no changes in per-member-per-month costs until all switch patients had 10 additional complex visits, in which per-member-per-month costs increased by $0.02. CONCLUSIONS: In a hypothetical plan of 1 million lives, use of biosimilar adalimumab in commercial plans can lead to significant cost savings for payers because of increased competition. Greater and faster biosimilar conversion rates from reference adalimumab and other reference TNF inhibitors resulted in decreased costs. Additionally, even with short-term medical expenditures, cost savings were still realized when switching to biosimilar adalimumab.
RESUMO
PURPOSE: Febrile neutropenia (FN) is a known side effect of chemotherapy, often requiring hospitalization. Economic burden increases with an FN episode and estimates of cost per episode should be updated from real-world data. METHODS: A retrospective claims analysis of FN episodes in patients with non-myeloid malignancies from 2014 to 2021 was performed in IQVIA PharMetrics® Plus database. FN episodes were defined as having same-day claims for neutropenia and fever or infection, plus antibiotic in outpatient settings, following a claim for chemotherapy; index date was defined as the first claim for neutropenia/fever/infection. Patients receiving bone marrow/stem cell transplant and CAR-T therapy were excluded, as were select hematologic malignancies or COVID-19. Healthcare utilization and costs were evaluated and described overall, by episode type (w/wo hospitalization), index year, malignancy type, NCI comorbidity score, and age group. RESULTS: 7,033 FN episodes were identified from 6,825 patients. Most episodes had a hospitalization (91.2%) and 86% of patients had ≥1 risk factor for FN. Overall, FN episodes had a mean (SD) FN-related cost of $25,176 ($39,943). Episodes with hospitalization had higher average FN-related costs versus those without hospitalization ($26,868 vs $7,738), and costs increased with comorbidity score (NCI=0: $23,095; NCI >0-2: $26,084; NCI ≥2: $26,851). CONCLUSIONS: FN continues to be associated with significant economic burden, and varied by cancer type, comorbidity burden, and age. In this analysis, most FN episodes were not preceded by GCSF prophylaxis. The results of this study highlight the opportunity to utilize GCSF in appropriate oncology scenarios.

ABSTRACT: A 51-year-old man with newly diagnosed small cell neuroendocrine carcinoma of the prostate was referred for a staging 18 F-DCFPyL PET/CT, which showed a solitary metastasis in the left acetabulum. Subsequent 18 F-FDG PET/CT showed intense uptake throughout the prostate as well as extensive avid pelvic and thoracic nodal disease and redemonstration of the left acetabular metastasis. Despite initial metabolic response to treatment, subsequent 18 F-FDG PET 8 months later revealed significant progression of nodal disease above and below the diaphragm, as well as multiple new sites of metastases.

Reorganization of neonatal intensive care by introducing clinical microsystems may help to allocate nursing time more appropriately to the needs of patients. However, there is concern that cohorting infants according to acuity may enhance noise levels. This single-center study investigated the impact of reorganization of neonatal intensive care unit by implementing clinical microsystems in a Level III NICU on environmental noise. This prospective study measured 24-h noise levels over a period of 6 months during pre- and post-implementation of microsystems cohorting infants of similar acuity. Comparative analyses of the mixed acuity (i.e., before) and the cohorting (i.e., after) model were performed by creating daily profiles from continuous noise level measurements and calculating the length of exposure to predefined noise levels. Compared to baseline daytime measurements, noise levels were 3-6 dBA higher during physician handover. Noise levels were 2-3 dBA lower on weekends and 3-4 dBA lower at night, independent of the organizational model. The introduction of clinical microsystems slightly increased average noise levels for high-acuity pods (A and B) but produced a much more substantial decrease for low-acuity pods (E), leading to an overall reduction in unit-wide noise levels. Conclusion: Our data show that noise levels are more driven by human behavior than by technical devices. Implementation of microsystems may help to reduce noise exposure in the lower acuity pods in a NICU. What is Known: ⢠Excessive noise levels can lead to adverse effects on the health and development of premature infants and other critically ill newborns. ⢠The reorganization of the neonatal intensive care unit following the clinical microsystems principles might improve quality of care but also affect noise exposure of staff and patients. What is New: ⢠The transition from a mixed -acuity to cohorting model is associated with an overall reduction in noise levels, particularly in low-acuity pods requiring less nursing care. ⢠Nevertheless, baseline noise levels in both models exceeded the standard permissible limits.

ABSTRACT: A 60-year-old man was referred for staging of prostate cancer. Initial CT scan demonstrated soft tissue lesions in bilateral renal hila, which demonstrated mild 68 Ga-PSMA avidity and moderate FDG avidity on sequential PET scans suspicious for malignancy. Biopsy confirmed adrenal cortical tissue. This case highlights an exceedingly rare occurrence of ectopic adrenocortical tissue in both renal hila.

Wnt signaling plays a crucial role in the early embryonic patterning and development, to regulate convergent extension during gastrulation and the establishment of the dorsal axis. Further, Wnt signaling is a crucial regulator of craniofacial morphogenesis. The adapter proteins Dact1 and Dact2 modulate the Wnt signaling pathway through binding to Disheveled, however, the distinct relative functions of Dact1 and Dact2 during embryogenesis remain unclear. We found that dact1 and dact2 genes have dynamic spatiotemporal expression domains that are reciprocal to one another and to wnt11f2l, that suggest distinct functions during zebrafish embryogenesis. We found that both dact1 and dact2 contribute to axis extension, with compound mutants exhibiting a similar convergent extension defect and craniofacial phenotype to the wnt11f2 mutant. Utilizing single-cell RNAseq and gpc4 mutant that disrupts noncanonical Wnt signaling, we identified dact1/2 specific roles during early development. Comparative whole transcriptome analysis between wildtype, gpc4 and dact1/2 mutants revealed a novel role for dact1/2 in regulating the mRNA expression of the classical calpain capn8. Over-expression of capn8 phenocopies dact1/2 craniofacial dysmorphology. These results identify a previously unappreciated role of capn8 and calcium-dependent proteolysis during embryogenesis. Taken together, our findings highlight the distinct and overlapping roles of dact1 and dact2 in embryonic craniofacial development, providing new insights into the multifaceted regulation of Wnt signaling.
RESUMO
BACKGROUND: Multiple sclerosis (MS) is chronic progressive disease that poses a significant economic burden to patients and health care systems in the United States. We conducted a systematic literature review to provide up-to-date insights on the economic burden of MS in the United States. OBJECTIVE: To comprehensively review and summarize the latest published evidence on the economic burden of MS with a focus on cost, resource use, and work productivity. METHODS: A systematic literature search was conducted using the Embase and Medline databases to identify studies, published between January 2011 and July 2022, reporting cost, resource use, or work productivity outcomes among people with MS in the United States. Clinical trials, economic modeling studies, and review articles were excluded. Details of eligible studies, including study design, patient population, and study outcomes for the overall population, as well as subgroups of interest, were extracted and summarized qualitatively. RESULTS: Overall, 65 studies reporting cost, resource use, or work productivity data were included with majority of studies using claims data. The direct costs associated with MS ranged from $16,614 (2006) to $72,744 (2017) per patient per year with diseasemodifying therapies (DMTs) being the major cost contributors accounting for 43%-78%. The indirect costs reported ranged from $9,122 (2017) to $30,601 (2011) per patient per year with absenteeism, early retirement, and informal care being the key drivers for indirect costs. Costs, resource use, and work impairment were significantly higher for patients with severe disability compared with those with mild disability. Pharmacy costs were the major cost drivers in patients with mild, moderate, and severe disability. Similarly, patients with relapses incurred significantly higher costs, resource use, and work impairment compared with those without relapses. Additional hospitalization charges were the major driver of higher costs in patients who experienced relapses compared with those without relapses. CONCLUSIONS: Direct costs, particularly DMTs, appear to be the major cost drivers for people with MS in the United States. Availability of lower-cost therapies may considerably decrease the economic burden on these patients and the health care systems. Future research focusing on indirect costs, intangible costs, and their contributors would contribute to further understanding of economic burden to avoid underestimation of the financial burden experienced by the patients.

BACKGROUND: Chemotherapy-induced neutropenia increases the risk of febrile neutropenia (FN) and infection with resultant hospitalizations, with substantial health care resource utilization (HCRU) and costs. Granulocyte-colony stimulating factor (GCSF) is recommended as primary prophylaxis for chemotherapy regimens having more than a 20% risk of FN. Yet, for intermediate-risk (10%-20%) regimens, it should be considered only for patients with 1 or more clinical risk factors (RFs) for FN. It is unclear whether FN prophylaxis for intermediate-risk patients is being optimally implemented. OBJECTIVE: To examine RFs, prophylaxis use, HCRU, and costs associated with incident FN during chemotherapy. METHODS: This retrospective study used administrative claims data for commercial and Medicare Advantage enrollees with nonmyeloid cancer treated with intermediate-risk chemotherapy regimens during January 1, 2009, to March 31, 2020. Clinical RFs, GCSF prophylaxis, incident FN, HCRU, and costs were analyzed descriptively by receipt of primary GCSF, secondary GCSF, or no GCSF prophylaxis. Multivariable Cox regression analysis was used to examine the association between number of RFs and cumulative FN risk. RESULTS: The sample comprised 13,937 patients (mean age 67 years, 55% female). Patients had a mean of 2.3 RFs, the most common being recent surgery, were aged 65 years or greater, and had baseline liver or renal dysfunction; 98% had 1 or more RFs. However, only 35% of patients received primary prophylaxis; 12% received secondary prophylaxis. The hazard ratio of incident FN was higher with increasing number of RFs during the first line of therapy, yet more than 54% of patients received no prophylaxis, regardless of RFs. Use of GCSF prophylaxis varied more by chemotherapeutic regimen than by number of RFs. Among patients treated with rituximab, cyclophosphamide, hydroxydaunorubicin hydrochloride (doxorubicin hydrochloride), vincristine, and prednisone, 76% received primary prophylaxis, whereas only 22% of patients treated with carboplatin/paclitaxel received primary prophylaxis. Among patients with a first line of therapy FN event, 78% had an inpatient stay and 42% had an emergency visit. During cycle 1, mean FN-related coordination of benefits-adjusted medical costs per patient per month ($13,886 for patients with primary prophylaxis and $18,233 for those with none) were driven by inpatient hospitalizations, at 91% and 97%, respectively. CONCLUSIONS: Incident FN occurred more often with increasing numbers of RFs, but GCSF prophylaxis use did not rise correspondingly. Variation in prophylaxis use was greater based on regimen than RF number. Lower health care costs were observed among patients with primary prophylaxis use. Improved individual risk identification for intermediate-risk regimens and appropriate prophylaxis may decrease FN events toward the goal of better clinical and health care cost outcomes.

BACKGROUND: Stories are powerful in their ability to disseminate information in a meaningful way. We hypothesized that a stem cell donation story library optimized for social media could support the education and recruitment of committed unrelated hematopoietic stem cell donors from needed demographic groups. STUDY DESIGN AND METHODS: We developed Why We Swab, a library of stories on stem cell donation (facebook.com/WhyWeSwab; instagram.com/WhyWeSwab; twitter.com/WhyWeSwab), and evaluated its impact across social and traditional media as well as on eligible potential donors' knowledge and attitudes towards donation. RESULTS: As of December 2021, the library included 28 story arcs featuring 45 storytellers from diverse ancestral backgrounds, including 8 donor-recipient stories. Overall, the stories reached >92,000 people across social media. Notably, stories were republished by 18 print/ broadcast media outlets in Canada and by major medical organizations. A series of stories shown to 33 eligible potential donors improved mean total scores on a donation knowledge test (64% to 85%, p < 0.001), reduced mean ambivalence scale scores (3.85 to 2.70, p < 0.001), and improved participants' willingness to register as donors (45% to 73%, p < 0.005). Data are also shown demonstrating that stakeholders valued the library and that its deployment was associated with improved donor recruitment outcomes in Canada. CONCLUSION: Why We Swab is accessible and relevant to a wide audience, including stem cell donor registries and recruitment organizations seeking to improve their recruitment efforts as well as to blood and organ & tissue donation organizations who can adapt the Why We Swab model to their audiences.

PURPOSE: Supportive oncodermatology has been shown to improve several aspects of care for patients with cancer, but research showing improved diagnostic accuracy as a benefit of supportive oncodermatology is largely lacking. We thus aimed to evaluate different dermatologist groups' diagnostic accuracy for heterogenous cutaneous toxicities, using cutaneous immune-related adverse events (cirAEs) from immune checkpoint inhibitors (ICIs) as a test model. METHODS: Billing/requisition codes were used to identify patients who initiated programmed death-1/ligand-1 (PD-1/PD-L1) ICIs between 2010 and 2019 at Dana-Farber Cancer Institute/Brigham and Women's Hospital/Massachusetts General Hospital and underwent a subsequent skin biopsy. For each biopsied cirAE, pre-biopsy clinical diagnoses and post-biopsy clinico-pathologic diagnoses were retrospectively obtained from the medical record. Each biopsy-ordering dermatology provider was categorized as a general dermatologist or supportive oncodermatologist on the basis of providing clinical care within a cancer-center or attending on a hospital/clinic service dedicated to anti-cancer drug-related skin toxicities. RESULTS: Of 4,183 patients who initiated anti-PD-1/PD-L1 therapy between 2010 and 2019, 101 (2.4%) patients collectively had 104 biopsied cirAEs. In more than one-third of all reviewed biopsied cirAEs (n = 39, 37.5%), histopathology results frequently led to revision of the pre-biopsy clinical diagnosis. The rate of initial cirAE misclassification amongst supportive oncodermatologists was significantly lower than that amongst general dermatologists (18/66, 27.3% vs. 21/38, 55.3%; Fischer's-exact-test p = 0.006). CONCLUSION: Experienced supportive oncodermatologists may benefit patient care through increased diagnostic accuracy for skin toxicities from ICIs. Collectively, these results underscore that both skin biopsy from any dermatology provider and oncodermatology referral (where available) are valuable resources that should be integrated into supportive cancer care.

INTRODUCTION: Febrile neutropenia (FN) is a major dose-limiting toxicity of myelosuppressive chemotherapy, and several patients receiving chemotherapy are at intermediate risk of developing FN. However, the guidelines remain less clear regarding the use of granulocyte colony-stimulating factors (G-CSFs) for this population and insights about real-world prophylaxis patterns and FN outcomes are needed. AREAS COVERED: This scoping review summarizes the variability in real-world G-CSF prophylaxis treatment patterns, incidence of FN, and associated outcomes among patients receiving chemotherapy at intermediate risk of FN. G-CSF PP use varied across the included studies (N = 23). Overall, there was a trend for reduced FN incidence among patients who received G-CSF PP vs. those who did not. G-CSF PP was also associated with a lower incidence of FN-related dose delays and reductions and fewer hospitalization days. Gaps in the literature of real-world studies exist, particularly around incorporating FN risk factor assessment, patient-reported outcomes, and health economic outcomes. EXPERT OPINION: Further studies are warranted to determine the impact of G-CSF PP use on clinical, quality of life, and economic outcomes in patients with intermediate FN risk, which could optimize care for this subgroup of patients, resulting in better population-based FN-related outcomes.

Background and Objectives Communities of practice (CoPs) represent effective models to achieve quality outcomes in health care. We report the development and evaluation of a CoP to improve stem cell donor recruitment in Canada. Materials and Methods In September 2017, we invited national stakeholders in stem cell donor recruitment to participate in a Facebook group and regular e-meetings. E-meetings involved speakers and roundtable discussion on topics related to donor recruitment. The Facebook group facilitated sharing of resources. We evaluated stakeholder perspective of the CoP and the impact on recruitment outcomes. Results As of December 2020, the CoP included 382 members who published 243 posts to the Facebook group about patient/donor stories (40%), resources (27%), updates/questions (21%) and recruitment outcomes (12%). In January 2020, we surveyed 44 CoP participants; the majority felt that the Facebook group (86%) and e-meetings (59%) supported the community, and that the CoP fostered collaboration (82%), improved their donor recruitment knowledge (75%) and practice (77%) and improved their ability to recruit needed donors (64%). The launch of the CoP correlated with improved donor recruitment outcomes. In 2016-2017, CoP participants recruited 2918 registrants (46% male; 55.9% non-Caucasian) compared to 4531 registrants in 2018-2019 (52.9% male; 62.7% non-Caucasian). Members of the CoP developed innovative resources to support recruitment efforts and led national campaigns securing coverage in major media outlets. Conclusion We describe the first CoP in stem cell donor recruitment to be formally evaluated. The CoP model may be adopted by donor recruitment organisations, registries and blood banks worldwide to improve recruitment outcomes. HIGHLIGHTS: ⢠A community of practice (CoP) in stem cell donor recruitment was valued by participants and supported efforts to improve recruitment outcomes. ⢠The CoP model may be adopted by donor recruitment organizations, donor registries, and blood banks worldwide to improve recruitment outcomes.

PURPOSE: Value-based programs, such as the Oncology Care Model (OCM), seek to improve care for patients undergoing chemotherapy, while reducing total costs. The purpose of this study is to quantify the impact of adopting biosimilar granulocyte colony-stimulating factors (G-CSFs) for febrile neutropenia (FN) primary prophylaxis (PP) from a US practice perspective. METHODS: A 1-year economic analysis on real-world direct drug costs and health care resource utilization was conducted in a hypothetical cohort of 500 patients with nonmyeloid cancer receiving chemotherapy. The first model simulated total cost savings of biosimilar versus reference G-CSFs over six cycles of chemotherapy. The second model evaluated cost and outcome implications of expanding the use of biosimilar G-CSFs to an additional 10% of patients at intermediate FN risk. RESULTS: Based on real-world evidence over 1 year, a total of 121 of 500 patients received G-CSF prophylaxis resulting in cost savings that ranged from $0.54M US dollars (USD) (short-acting, eg, filgrastim) to $1.68M USD (long-acting, eg, pegfilgrastim) when switching from reference to biosimilar G-CSFs. Expanding the use of biosimilar G-CSFs allowed an additional 24 patients to receive prophylaxis of FN, leading to cost savings of $0.03M USD or $1.19M USD, with a reduction of $0.08M USD in FN-related resource utilization cost. The per-patient per-year cost saving for long-acting G-CSFs was about $3,000 USD. CONCLUSION: The implementation of biosimilar versus reference G-CSFs to OCM-participating practices results in a reduction of costs and facilitates achieving OCM metrics by improving patients' outcomes while expanding biosimilar G-CSFs access to patients at intermediate risk of chemotherapy-induced FN.

BACKGROUND: Pegfilgrastim is available as a prefilled syringe (PFS) and an on-body injector (OBI). Whether the administration method of pegfilgrastim affects the effectiveness and health care resources has not been evaluated in the setting of routine care. OBJECTIVE: To compare real-world clinical and economic outcomes between PFS and OBI methods of administration. METHODS: This was a retrospective observational study in patients diagnosed with breast cancer or non-Hodgkin lymphoma who received myelosuppressive chemotherapy and prophylactic use of pegfilgrastim via PFS or OBI between January 1, 2017, and May 31, 2018, according to MarketScan research databases. A propensity score was used to match the PFS cohort 1:1 to the OBI cohort. Outcomes were compared among the matched cohorts using a generalized linear model and generalized estimating equations with log-link function. RESULTS: 3,152 patients were identified. After matching, the final sample included 2,170 patients, representing 1,085 in each cohort. The incidence of febrile neutropenia (FN) in the first chemotherapy cycle was 1.01% for OBI (95% CI = 0.56-1.82) vs 1.48% for PFS (95% CI = 0.91-2.39; P = 0.336). In all chemotherapy cycles (total cycles = 7,467), the FN incidence was 0.91% for OBI (95% CI = 0.64-1.30) vs 1.22% for PFS (95% CI = 0.90-1.64; P = 0.214). There was no statistically significant difference in adjusted per-member per-month all-cause total cost health care resource utilization (HCRU) for hospitalizations, emergency department visits, and pharmacy claims. CONCLUSIONS: In a matched cohort of patients representing real-world utilization, there was no statistically or clinically meaningful difference in FN incidence between OBI and PFS methods of pegfilgrastim administration. There was no difference in total HCRU or total costs. OBI and PFS methods of administration are both indicated for patients requiring prophylactic pegfilgrastim, which is important considering that biosimilar PFS options are now available.

PURPOSE: Temporary COVID-19 guideline recommendations have recently been issued to expand the use of colony-stimulating factors in patients with cancer with intermediate to high risk for febrile neutropenia (FN). We evaluated the cost-effectiveness of primary prophylaxis (PP) with biosimilar filgrastim-sndz in patients with intermediate risk of FN compared with secondary prophylaxis (SP) over three different cancer types. METHODS: A Markov decision analytic model was constructed from the US payer perspective over a lifetime horizon to evaluate PP versus SP in patients with breast cancer, non-small-cell lung cancer (NSCLC), and non-Hodgkin lymphoma (NHL). Cost-effectiveness was evaluated over a range of willingness-to-pay thresholds for incremental cost per FN avoided, life year gained, and quality-adjusted life year (QALY) gained. Sensitivity analyses evaluated uncertainty. RESULTS: Compared with SP, PP provided an additional 0.102-0.144 LYs and 0.065-0.130 QALYs. The incremental cost-effectiveness ranged from $5,660 in US dollars (USD) to $20,806 USD per FN event avoided, $5,123 to $31,077 USD per life year gained, and $7,213 to $35,563 USD per QALY gained. Over 1,000 iterations, there were 73.6%, 99.4%, and 91.8% probabilities that PP was cost-effective at a willingness to pay of $50,000 USD per QALY gained for breast cancer, NSCLC, and NHL, respectively. CONCLUSION: PP with a biosimilar filgrastim (specifically filgrastim-sndz) is cost-effective in patients with intermediate risk for FN receiving curative chemotherapy regimens for breast cancer, NSCLC, and NHL. Expanding the use of colony-stimulating factors for patients may be valuable in reducing unnecessary health care visits for patients with cancer at risk of complications because of COVID-19 and should be considered for the indefinite future.
