Abstract
Background: Sleep is increasingly recognized as essential to human health, yet the adverse health consequences of acute sleep deprivation are unknown. We hypothesized that acute sleep deprivation is associated with health outcomes and modulated by sleep-associated genotypes. Methods: LOESS smoothing was performed on sleep estimates from Fitbit users (N = 14,681) between June 1, 2016 and July 1, 2022. Dates when population minutes slept were less than the 90% confidence interval of the LOESS regression were named acute sleep deprivation events (ASDEs). Phenome-wide disease incidence among the AoU population (N = 287,012) in the 10 days post-ASDE was compared to a preceding reference period by McNemar test. Circadian rhythm and sleep duration-associated SNPs were screened to identify genotypes associated with shorter ASDE sleep duration. Influences of sleep and circadian genotype on post-ASDE influenza risk were modeled using binomial family generalized estimating equations. Results: We identified 32 ASDEs spanning major national events. A phenome-wide screen found increased risk of influenza (OR = 1.54 [1.40, 1.70], P-value = 1.00 x 10-18) following ASDEs. 56 SNPs were associated with decreased sleep duration on ASDEs. Higher quantiles of ASDE-related SNP genotype burden were associated with less ASDE sleep duration and a greater risk of influenza-associated healthcare visits. Conclusion: Major national events are associated with acute sleep deprivation and greater influenza risk which is amplified by sleep genotypes. These findings should inform public health vigilance surrounding major national events.

Abstract
BACKGROUND Icotrokinra is the first and only targeted oral peptide that selectively binds the IL-23 receptor with high affinity to precisely inhibit IL-23 signaling. Icotrokinra demonstrated high rates of complete skin clearance and durable disease control in the phase IIb trial, FRONTIER-1, and its long-term extension, FRONTIER-2, in participants with moderate-to-severe plaque psoriasis. This study evaluated systemic and skin pharmacodynamic response of icotrokinra and its relationship to clinical response in FRONTIER participants.METHODS FRONTIER-1 participants received icotrokinra or placebo for 16 weeks. FRONTIER-2 followed participants for up to 1 year of treatment; placebo participants transitioned to icotrokinra after week 16. Systemic pharmacodynamic changes were assessed in serum through week 52. Skin pharmacodynamic changes were assessed using transcriptomic analysis of skin biopsies and protein quantification in tape-strip samples through week 16.RESULTS Icotrokinra dose-dependently reduced serum levels of the IL-23/IL-17 axis and psoriasis disease biomarkers through week 52, with maximal reductions observed with the highest 100 mg twice-daily dose. Proteomic analyses showed icotrokinra selectively blocked IL-23–driven inflammation without broader impacts on circulating proteins, including serum IL-23 levels. Sixteen weeks of icotrokinra, but not placebo, reduced expression of psoriasis-associated genes in lesional skin. Icotrokinra treatment also reduced psoriasis-relevant proteins in week 16 lesional skin tape-strips to levels comparable to nonlesional samples.CONCLUSION Icotrokinra induced a dose-dependent pharmacodynamic response, with early (week 4) and sustained (week 52) reductions in biomarkers of IL-23 pathway activation and psoriasis disease severity, which correlated with clinical response.TRIAL REGISTRATION ClinicalTrials.gov: NCT05223868, NCT05364554.FUNDING Johnson & Johnson.

Abstract
BACKGROUND Platelets are increasingly recognized as active participants in immune signaling and systemic inflammation. Upon activation, platelets form monocyte platelet aggregates (MPA) representing the crossroads of thrombosis and inflammation. We hypothesized that platelet transcriptomics could capture this thromboinflammatory axis and identify individuals at elevated cardiovascular risk.METHODS: MPA levels, defined as CD14+CD61+ cells, were measured using flow cytometry at 2 time points, 4 weeks apart, in healthy individuals Platelets were isolated and sequenced. Individuals were categorized as MPAhi or MPAlo based on consistently high or low MPA levels across time points.RESULTS Among 149 participants (median age 52 years, 57% female, 50% non-White), MPAhi individuals exhibited increased expression of platelet activation markers P-selectin (P < 0.001), PAC-1 (P = 0.021), and CD40L (P < 0.001) and enriched immune signaling pathways. Informed by MPA levels and derived from the platelet transcriptome, we developed a 42-gene thromboinflammation platelet signature (TIPS), which correlated with MPA levels in multiple cohorts and was reproducible over time. TIPS was elevated in patients with COVID-19 (P = 0.0002) and myocardial infarction (Padj = 0.008), and as in predicted future cardiovascular events in patients who underwent lower extremity revascularization after a median follow-up of 18 months (adjusted for age, sex, race, and ethnicity [adjHR] 1.55, P = 0.006). Notably, TIPS was modifiable by ticagrelor (P = 0.002) but not aspirin.CONCLUSION These findings establish MPA as a biomarker of thromboinflammation and introduce TIPS, a platelet RNA signature, that captures thromboinflammation and provides a promising tool for cardiovascular risk stratification and a potential therapeutic target.TRIAL REGISTRATION NCT04369664FUNDING NIH R35HL144993, NIH R01HL139909, and AHA 16SFRN2873002 to JSB, DFG Walter-Benjamin-Programme 537070747 to AB.

Abstract
BACKGROUND. Chimeric antigen receptor (CAR) T-cells are a leading immunotherapy for refractory B-cell malignancies; however, their impact is limited by toxicity and incomplete efficacy. Daily (circadian) rhythms in immune function may offer a lever to boost therapeutic success; however, their clinical relevance to CAR T-cell therapy remains unknown. METHODS. We retrospectively analyzed CAR T-cell survival and complications based on infusion time at two geographically distinct hospitals in St. Louis, Missouri (n=384), and Portland, Oregon (n=331) between 1/2018 and 3/2025. The primary outcome was 90-day overall survival (OS). Secondary outcomes included event-free survival (EFS), cytokine release syndrome (CRS), immune cell-associated neurotoxicity syndrome (ICANS), ICU admission, shock, respiratory failure, and infection. We quantified the independent relationship between infusion time and outcomes using multivariable mixed-effects logistic regression and time-to-event models, adjusting for patient, oncologic, and treatment characteristics. RESULTS. The therapeutic index of CAR-T cells inversely correlated with administration time, with later infusions associated with lower effectiveness and more adverse outcomes. For each hour that CAR T-cell treatment was delayed, the adjusted odds of 90-day mortality increased by 24% (aOR 0.64-0.88, p=<0.001), severe neurotoxicity by 17% (p=0.023), and mechanical ventilation by 27% (p=0.026). These temporal patterns were most pronounced in patients receiving CD19-targeting CAR T-cell products. In contrast, we did not find an association between infusion time and severe CRS (aOR 0.99, 95% CI 0.75–1.27, p=0.92). CONCLUSION. Time of day is a potent and easily modifiable factor that could optimize CAR T-cell clinical performance. FUNDING. National Institutes of Health.

Abstract
BACKGROUND. WP1066 is an orally bioavailable, small molecule inhibitor of activated p-STAT3 that has demonstrated preclinical efficacy in pediatric brain tumor models. METHODS. In a first-in-child, single-center, single-arm 3+3 design Phase I clinical trial, ten patients were treated with WP1066 twice daily, Monday-Wednesday-Friday, for 14 days of each 28-day cycle to determine the maximum tolerated dose (MTD)/maximum feasible dose (MFD) of WP1066. Compassionate use treatment with WP1066 in three pediatric patients with H3.3 G34R/V-mutant high-grade glioma (HGG) is also described. RESULTS. There was no significant toxicity and the MFD was determined to be 8 mg/kg. Treatment-related adverse events were Grade 1-2 (diarrhea and nausea most common); there were no dose-limiting toxicities. Median progression-free and overall survival were 1.8 months and 4.9 months, respectively. One partial response was observed in a patient with pontine glioma. Among the H3.3 G34R/V-mutant HGG patients not on study, WP1066 was administered after upfront radiation to one patient for 17 months. At all dose levels tested, WP1066 suppressed p-STAT3 expression by peripheral blood mononuclear cells (PBMCs). Single cell RNA-seq analysis of PBMCs demonstrated increased CD4+ and CD8+ T cells, pro-inflammatory TNFA signaling, differentiation activity in myeloid cells, and downregulation of Tregs after WP1066 treatment, consistent with systemically inhibited STAT3 activity. CONCLUSIONS. WP1066 is safe, has minimal toxicity, and induces anti-tumor immune responses in pediatric brain tumor patients. Phase II investigation of WP1066 at the MFD in this patient population is warranted. TRIAL REGISTRATION. ClinicalTrials.gov NCT04334863. FUNDING. CURE Childhood Cancer (TJM) and Peach Bowl, Inc.

Abstract
BACKGROUND Suboptimal fetal growth (SFG), being born small for gestational age (SGA), and catch-up (CU) growth are, individually and together, linked to cardiometabolic risks. However, not all develop adverse outcomes. This study aimed to validate a transcriptomic signature to identify individuals at greatest cardiometabolic risk.METHODS Using National Heart, Lung and Blood Institute (NHLBI) criteria to define cardiometabolic risk, healthy and prehypertensive 17-year-olds were identified in the Avon Longitudinal Study of Parents and Children (ALSPAC) (UK) childhood cohort. Epigenomic and transcriptomic differences were analyzed. A hypergraph identified functionally related genes, which were used in random forest classification to predict prehypertensive phenotypes. The BabyGRO (UK) cohort included 80 children aged 3–7 years, born at term following pregnancies with SFG risks. Anthropometric and cardiometabolic markers and transcriptomic profiles were collected, fetal and childhood weight trajectories and their relationship to cardiometabolic markers were assessed, and transcriptome was used for prediction.RESULTS Individuals with CU-SGA in ALSPAC were 1.6 times more likely than all others to be prehypertensive at 17 years (P < 1 × 10–5). A 42-gene hypergraph cluster was highly predictive of prehypertension (AUC 0.984, error rate 5.4%). In BabyGRO, 20 of these genes accurately predicted higher systolic blood pressure (AUC 0.971, error rate 3.6%). This transcriptomic signature could help identify children with adverse pre- and postnatal growth who may develop prehypertension.CONCLUSION A blood transcriptomic signature exists in childhood which distinguishes those at risk of adult cardiometabolic disease among children with adverse pre- and postnatal growth.TRIAL REGISTRATION Regional ethics committee reference 17/NW/0153, IRAS project ID 187679.FUNDING Centre grant to the Maternal and Fetal Health Research Centre by Tommy’s The Pregnancy and Baby Charity, Child Growth Foundation, European Research Council funding as part of the Health and Environment-wide Associations based on Large Population Surveys (HEALS) study

Abstract
The biological age of organs may better quantify risk for health deterioration compared with chronological age. We investigated organ-specific aging patterns in a community-based cohort and assessed the associations with adverse health outcomes. Biological ages of 11 organs were estimated for 11,757 participants of the Atherosclerosis Risk in Communities (ARIC) study (55.6% women, mean age, 57.1 years) using a circulating protein–based model. Older organ ages were significantly associated with related adverse outcomes, even after accounting for chronological age; for example, older arteries and hearts were associated with an increased risk for coronary heart disease (CHD; hazard ratio [HR] per 5-year-higher age gap, 1.22; 95% CI [1.13–1.31] and 1.16 [1.07–1.26], respectively, and older lungs with lung cancer (HR 1.12 [1.09–1.16]). Hierarchical agglomerative clustering based on organ ages revealed 3 patient phenotypes: those with older organs, normal/slightly older organs, and younger organs. The patients with older organs were at higher risk for cancer (HR 1.19; 95% CI [1.08–1.31]), death (HR 1.75 [1.64–1.86]), end-stage kidney disease (HR 6.12 [4.65–8.06]), CHD (HR 1.21 [1.06–1.38]), heart failure (HR 1.92 [1.73–2.13]), infection (HR 1.56 [1.44–1.68]), and stroke (HR 1.36 [1.16–1.61]). Proteomic organ aging signatures demonstrated significant associations with multiple adverse health outcomes and may be useful for health risk identification.

Abstract
Immune checkpoint inhibitors (ICIs) such as anti-PD-1 and anti-CTLA-4 antibodies are used to induce an immune response against many types of tumors. However, ICIs often also induce autoimmune responses, referred to as immune-related adverse events (irAEs), which occur unpredictably and at varying levels of severity in ICI-treated patients. The immunologic factors that predispose patients to the development of severe irAE are largely unclear. Here, we utilized high dimensional mass cytometry immunophenotyping of longitudinal blood samples from patients with metastatic melanoma treated with combination anti-PD-1/CTLA4 ICI therapy in the context of a clinical trial to characterize alterations in immune profiles induced by combination ICI therapy and to identify immune features associated with development of severe irAEs. Deep T cell profiling highlighted that ICI therapy induces prominent expansions of activated, CD38hi CD4+ and CD8+ T cells, which are frequently bound by the therapeutic anti-PD-1 antibody, as well as substantial changes in regulatory T cell phenotypes. However, neither the baseline frequency nor the extent of expansion of these cell populations was associated with development of severe irAEs. Rather, single cell-association testing revealed naïve CD4+ T cell abundance pre-treatment as significantly associated with the development of severe irAEs. Biaxial gating of naïve CD4+ T cells confirmed a significant positive association of naïve CD4+ T cell proportion and development of a severe irAE and with the number of irAEs developed in this cohort. Results from this broad profiling study indicate the abundance of naïve CD4+ T cells as a predictive feature for the development of severe irAEs following combination anti-PD-1/CTLA4 ICI therapy.

Abstract
BACKGROUND. Individuals with autoimmune diseases (AD) on immunosuppressants often have suboptimal responses to COVID-19 vaccine. We evaluated the efficacy and safety of additional COVID-19 vaccines in those treated with mycophenolate mofetil/mycophenolic acid (MMF/MPA), methotrexate (MTX), and B cell-depleting therapy (BCDT), including the impact of withholding MMF/MPA and MTX. METHODS. In this open-label, multicenter, randomized trial, 22 participants taking MMF/MPA, 26 taking MTX, and 93 treated with BCDT who had suboptimal antibody responses to initial COVID-19 vaccines (2 doses of BNT162b2 or mRNA-1273 or 1 dose of AD26.COV2.S) received an additional homologous vaccine. Participants taking MMF/MPA and MTX were randomized (1:1) to continue or withhold treatment around vaccination. The primary outcome was the change in anti-Wuhan-Hu-1 receptor-binding domain (RBD) concentrations at 4 weeks post-additional vaccination. Secondary outcomes included adverse events, COVID-19 , and AD activity through 48 weeks. RESULTS. Additional vaccination increased anti-RBD concentrations in participants taking MMF/MPA and MTX , irrespective of immunosuppressant withholding. BCDT-treated participants also demonstrated increased anti-RBD concentrations, albeit lower than MMF/MPA- and MTX-treated cohorts. COVID-19 occurred in 33% of participants; infections were predominantly mild and included only three non-fatal hospitalizations. Additional vaccination was well-tolerated, with low frequencies of severe disease flares and adverse events. CONCLUSION. Additional COVID-19 vaccination is effective and safe in individuals with ADs treated with immunosuppressants, regardless of whether MMF/MPA or MTX is withheld. TRIAL REGISTRATION.

Abstract
BACKGROUND. Cannabidiol (CBD) is increasingly used for pain management, including in transplant recipients with limited analgesic options. Its immunomodulatory effects in humans are not well defined at a single cell level at CBD steady state with concomitant tacrolimus treatment. METHODS. In a Phase 1 ex vivo study, peripheral blood mononuclear cells from 23 participants who received oral CBD (Epidiolex®) up to 5 mg/kg twice daily for 11 days were collected before CBD (pre-CBD) and at steady state (post-CBD). Lymphocytes were isolated and stimulated with anti-CD3/CD28 antibodies, with or without tacrolimus (5 ng/mL). Pharmacodynamic responses were assessed using CellTiter-Glo® proliferation, single-cell/nucleus RNA sequencing, cytokine assays, and flow cytometry. Steady-state plasma concentrations of CBD were quantified via tandem mass spectrometry. RESULTS. We identified an increased proportion of T effector memory (TEM) cells post-cannabidiol (22% increase), which correlated with CBD plasma concentrations (R = 0.77, P-value = 0.01). Cannabidiol reduced proliferation of T (37% decrease) and CD70hi B (17% decrease) lymphocytes with additive immunosuppressive effects to tacrolimus. Single-cell RNA sequencing revealed reduced IL2 and TNF signaling and altered receptor–ligand networks in TEM cells. Post-cannabidiol cytokine assays revealed elevated proinflammatory IL-6 protein levels and anti-inflammatory IL-10 levels, with reduced TNF-α, LTA, and IL-2. In flow cytometry, the proportion of TEM and TEMRA increased post-cannabidiol with tacrolimus. CONCLUSION. Cannabidiol exhibits mixed immunomodulatory effects with pro- and anti-inflammatory signals. Understanding the clinical safety of cannabidiol use is important given the paucity of pain control options available for immunocompromised transplant populations.
