RESUMO

Remote inflammation monitoring with digital health technologies (DHTs) would provide valuable information for both clinical research and care. Controlled perturbations of the immune system may reveal physiological signatures which could be used to develop a digital biomarker of inflammatory state. In this study, molecular and physiological profiling was performed following an in vivo lipopolysaccharide (LPS) challenge to develop a digital biomarker of inflammation. Ten healthy volunteers received an intravenous LPS challenge and were monitored for 24 h using the VitalConnect VitalPatch (VitalPatch). VitalPatch measurements included heart rate (HR), heart rate variability (HRV), respiratory rate (RR), and skin temperature (TEMP). Conventional episodic inpatient vital signs and serum proteins were measured pre- and post-LPS challenge. The VitalPatch provided vital signs that were comparable to conventional methods for assessing HR, RR, and TEMP. A pronounced increase was observed in HR, RR, and TEMP as well as a decrease in HRV 1-4 h post-LPS challenge. The ordering of participants by magnitude of inflammatory cytokine response 2 h post-LPS challenge was consistent with ordering of participants by change from baseline in vital signs when measured by VitalPatch (r = 0.73) but not when measured by conventional methods (r = -0.04). A machine learning model trained on VitalPatch data predicted change from baseline in inflammatory protein response (R2 = 0.67). DHTs, such as VitalPatch, can improve upon existing episodic measurements of vital signs by enabling continuous sensing and have the potential for future use as tools to remotely monitor inflammation.

RESUMO

ABSTRACT: The symptoms of pernicious anemia might resemble those of other common disorders and can be nonspecific, requiring extensive diagnostic workup. The provider must be aware of the harm pernicious anemia can do if undiagnosed and untreated and must understand that diligence and persistence are crucial for an accurate diagnosis.

RESUMO

Given the key role of the IL-23/Th17 axis in the pathogenesis of moderate-to-severe plaque psoriasis, several specific inhibitors of the p19 subunit of IL-23 have been approved to treat this chronic inflammatory disease. Clinical data indicate that guselkumab, one such selective IL-23 inhibitor, achieves greater clinical efficacy compared with ustekinumab, which inhibits both IL-12 and IL-23 via binding their shared p40 subunit. To understand mechanisms underlying the enhanced efficacy observed with the p19 subunit of IL-23-specific inhibition, we explored cellular and molecular changes in skin of psoriasis patients treated with ustekinumab or guselkumab and in ustekinumab inadequate responders (Investigator's Global Assessment of psoriasis score ≥ 2) subsequently treated with guselkumab (ustekinumab→guselkumab). Skin biopsies were collected pretreatment and posttreatment to assess histologic changes and molecular responses in ustekinumab- and guselkumab-treated patients. Serum cytokines and skin transcriptomics from the subset of ustekinumab→guselkumab-treated patients were also analyzed to characterize differential treatment effects. Ustekinumab and guselkumab demonstrated differential effects on secretion of pathogenic Th17-related cytokines induced by IL-23 in in vitro assays, which suggest guselkumab is a more potent therapeutic agent. Consistent with these findings, guselkumab elicited a significantly greater reduction in cellular and molecular psoriasis-related disease indicators than ustekinumab. In ustekinumab→guselkumab patients, suppression of serum IL-17A and IL-17F levels and neutralization of molecular scar and psoriasis-related gene markers in skin were significantly greater compared with patients continuing ustekinumab. This comparative study demonstrates that guselkumab inhibits psoriasis-associated pathology, suppresses Th17-related serum cytokines, and normalizes the psoriasis skin gene expression profile more effectively than ustekinumab.

RESUMO

BACKGROUNDAntigen-specific regulation of autoimmune disease is a major goal. In seropositive rheumatoid arthritis (RA), T cell help to autoreactive B cells matures the citrullinated (Cit) antigen-specific immune response, generating RA-specific V domain glycosylated anti-Cit protein antibodies (ACPA VDG) before arthritis onset. Low or escalating antigen administration under "sub-immunogenic" conditions favors tolerance. We explored safety, pharmacokinetics, and immunological and clinical effects of s.c. DEN-181, comprising liposomes encapsulating self-peptide collagen II259-273 (CII) and NF-κB inhibitor 1,25-dihydroxycholecalciferol.METHODSA double-blind, placebo-controlled, exploratory, single-ascending-dose, phase I trial assessed the impact of low, medium, and high DEN-181 doses on peripheral blood CII-specific and bystander Cit64vimentin59-71-specific (Cit-Vim-specific) autoreactive T cell responses, cytokines, and ACPA in 17 HLA-DRB1*04:01+ or *01:01+ ACPA+ RA patients on methotrexate.RESULTSDEN-181 was well tolerated. Relative to placebo and normalized to baseline values, Cit-Vim-specific T cells decreased in patients administered medium and high doses of DEN-181. Relative to placebo, percentage of CII-specific programmed cell death 1+ T cells increased within 28 days of DEN-181. Exploratory analysis in DEN-181-treated patients suggested improved RA disease activity was associated with expansion of CII-specific and Cit-Vim-specific T cells; reduction in ACPA VDG, memory B cells, and inflammatory myeloid populations; and enrichment in CCR7+ and naive T cells. Single-cell sequencing identified T cell transcripts associated with tolerogenic TCR signaling and exhaustion after low or medium doses of DEN-181.CONCLUSIONThe safety and immunomodulatory activity of low/medium DEN-181 doses provide rationale to further assess antigen-specific immunomodulatory therapy in ACPA+ RA.TRIAL REGISTRATIONAnzctr.org.au identifier ACTRN12617001482358, updated September 8, 2022.FUNDINGInnovative Medicines Initiative 2 Joint Undertaking (grant agreement 777357), supported by European Union's Horizon 2020 research and innovation programme and European Federation of Pharmaceutical Industries and Associations; Arthritis Queensland; National Health and Medical Research Council (NHMRC) Senior Research Fellowship; and NHMRC grant 2008287.

RESUMO

OBJECTIVE: The objective of this review is to develop a definition of biofortification through the synthesis of food biofortification publications and to document the breadth of the research on this topic. INTRODUCTION: Biofortification of a food source is a human health intervention. Due to the varying definitions of this concept, biofortification can be difficult to describe. Originally, biofortification was defined as the use of plant breeding methods to produce staple foods dense in minerals and vitamins. Research using the term focused on mineral, vitamin, and protein improvement of staple foods. However, the field has expanded to include non-staple foods as well as different methodological approaches to biofortification (eg, transgenic, molecular breeding). Researchers require a broad overview of the evidence and consensus on a definition to ensure effective communication within this scientific community. INCLUSION CRITERIA: Inclusion criteria will be broad to ensure that existing definitions of biofortification are captured across the different areas of study in this field. The review will consider research published in English. Inclusion will not be limited by participant type, date of publication, or context. The concept will be strictly biofortification. METHODS: A broad search strategy will be utilized for AGRICOLA, AGRIS, Web of Science, PubAg, CINAHL, PubMed, Cochrane Library, Epistemonikos, JBI Evidence Synthesis, Google Scholar, and Washington State University Libraries' integrated catalog. A limited search for gray literature will be conducted. The data extracted will include study and author characteristics. Tables and figures will demonstrate the breadth of the evidence.

RESUMO

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.

RESUMO

There are known geographical differences in growth hormone deficiency (GHD) patient populations and treatment practices. Here, we present a comparison of safety and effectiveness data from patients treated with recombinant human growth hormone (rhGH) in the USA versus other countries. PAtients TReated with Omnitrope® (PATRO) Children is an international, non-interventional study with Omnitrope® (somatropin, Sandoz Inc.). All visits and assessments are carried out according to routine clinical practice, and doses of Omnitrope® are given according to country-specific prescribing information. By September 2018, 294 patients had been enrolled in the USA (53% rhGH-naïve) and 6206 patients had been enrolled across 13 other countries (international group; 86% rhGH-naïve). The most common indication in both groups was GHD. Overall, 194 US patients (66%) and 2977 international patients (48%) experienced adverse events (AEs; 886 and 11,716 events, respectively), most of which were of mild or moderate intensity. The AEs were suspected to be treatment-related in five US patients (1.7%) and 452 international patients (7.3%). All reported neoplasms were benign, non-serious, and considered unrelated to rhGH therapy. No cases of diabetes mellitus or hyperglycemia were reported. In rhGH-naïve GHD patients, after 3 years of rhGH therapy, the improvement in mean height SD score from baseline was + 1.25 and + 1.35 in US and international patients, respectively. CONCLUSION: Omnitrope® treatment appears to be well tolerated and effective in US patients and those from other countries. Across the pediatric indications included, there was no evidence of an increased risk of developing uncommon or unexpected AEs with rhGH. TRIAL REGISTRATION: NA. WHAT IS KNOWN: • Continued monitoring of patients treated with recombinant human growth hormone (rhGH) is important, particularly in terms of diabetogenic potential and the risk of malignancies. • The PAtients TReated with Omnitrope® (PATRO) Children study is a long-term, post-marketing surveillance program for the rhGH Omnitrope®. WHAT IS NEW: • Omnitrope® is well tolerated and effective in US patients, and those from other countries. • Across all indications included, there were no unexpected adverse events and there was no evidence of an increased risk of developing malignancies or diabetes.

RESUMO

Antigen-specific T cells can serve as a response biomarker in non-clinical or clinical immunotherapy studies in autoimmune disease. There are protocols with optimized multimer staining methods to detect peptide (p)MHCII+ CD4+ T cells, and some qualified and validated protocols for pMHCI+ CD8+ T cells. However, no protocol is fully or partially qualified to enumerate and characterize antigen-specific pMHCII+ CD4+ T cells from patient samples. Implementing such an assay requires a desired level of specificity and precision, in terms of assay repeatability and reproducibility. In transgenic type II collagen (CII)-immunized HLA-DR1/DR4 humanized mouse models of collagen-induced arthritis (CIA), CII259-273-specific T cells dominantly expand. Therefore antigen-specific T cells recognizing this epitope presented by rheumatoid arthritis (RA)-associated risk HLA-DR allomorphs are of interest to understand disease progression and responses to immunotherapy in RA patients. Using HLA-DRB1∗04:01 or ∗01:01-collagen type II (CII)259-273 tetramers, we evaluated parameters influencing precision and reproducibility of an optimized flow cytometry-based method for antigen-specific CD4+ T cells and eight specific subpopulations with and without tetramer positivity. We evaluated specificity, precision, and reproducibility for research environments and non-regulated laboratories. The assay has excellent overall precision with %CV<25% for intra-assay repeatability, inter-analyst precision, and inter-assay reproducibility. The precision of the assay correlated negatively with the cell viability after thawing, indicating that post-thaw viability is a critical parameter for reproducibility. This assay is suitable for longitudinal analysis of treatment response and disease activity outcome in RA patients, and adaptable for translational or immunotherapy clinical trial settings.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

OBJECTIVES: Omnitrope® (somatropin, Sandoz Inc.) is one of several recombinant human growth hormones (rhGH) approved in the United States (US) for use in pediatric indications, including growth hormone deficiency (GHD) and idiopathic short stature (ISS). We report data on the effectiveness and safety of Omnitrope® in the US cohort of the PATRO Children (international, longitudinal, non-interventional) study. METHODS: All visits and assessments are carried out according to routine clinical practice, and doses of Omnitrope® are given according to country-specific prescribing information. RESULTS: By September 2018, 294 US patients were recruited; the two largest groups were GHD (n=193) and ISS (n=62). Across all indications, HSDS improvement (ΔHSDS) from baseline at three years was +1.0 (rhGH-naïve, +1.2; pre-treated, +0.7). In pre-pubertal patients, ΔHSDS from baseline at three years was +0.94 (rhGH-naïve, +1.3; pre-treated, +0.7). Following three years of treatment, ΔHSDS from baseline was +1.3 in rhGH-naïve GHD patients and +1.1 in rhGH-naïve ISS patients. In pre-pubertal rhGH-naïve patients, ΔHSDS from baseline was +1.3 and +1.2 in GHD and ISS patients, respectively. Overall, 194 patients (66.0%) experienced adverse events (AEs; n=886 events); most were of mild-moderate intensity. Five patients (1.7%) had AEs that were suspected to be treatment-related (n=5 events). All reported neoplasms were benign, non-serious, and considered unrelated to rhGH therapy. No AEs of diabetes mellitus or hyperglycemia were reported. CONCLUSIONS: Omnitrope® appears to be well tolerated and effective in the majority of patients, without evidence of an increased risk of developing unexpected AEs, diabetes mellitus, or new malignancies during treatment.
