BACKGROUND We constructed multi-trait polygenic risk scores (PRSs) predicting chronic obstructive pulmonary disease (COPD) and exacerbations, validated their performance in diverse cohorts, and identified PRS-related proteins for potential therapeutic targeting. METHODS PRSmix + , a multi-trait PRS framework, is used to train a composite PRS (PRS multi ) in COPDGene non-Hispanic White participants ( n = 6,647). Associations of PRS multi with COPD status (GOLD 2–4 vs. GOLD 0 or ICD) and exacerbation frequency were tested in COPDGene African American ( n = 2,466), ECLIPSE ( n = 1,858), Mass General Brigham Biobank ( n = 15,152), and All of Us ( n = 118,566). Protein prediction models were applied to GWAS summary statistics from traits contributing to PRS multi and were validated with proteomic data in COPDGene ( n = 5,173) and UK Biobank ( n = 5,012). RESULTS PRSmix + selected 7 traits for PRS multi . In multivariable models, PRS multi was associated with COPD status (meta-analysis random effects [RE] OR 1.58 [95% CI: 1.28–1.94]) and exacerbation frequency (meta-analysis RE β 0.21 [95% CI: 0.11–0.31]), with higher effect sizes observed in smoking-enriched cohorts. PRS multi outperformed traditional single-trait PRS in all tested cohorts. Using protein prediction models, we identified 73 proteins associated with the PRSs that were also validated with measured protein levels in COPDGene and UK Biobank. Of these proteins, 25 were linked to approved or investigational drugs. Notable targets include RAGE/sRAGE, IL1RL1, and SCARF2, all implicated in COPD pathogenesis and exacerbations. CONCLUSIONS Multi-trait PRS improves prediction of COPD and exacerbation risk. Integration with proteomic data identifies druggable protein targets, offering a promising avenue for precision medicine in COPD management.

ABSTRACT Background Preoperative vascular embolization (PVE) is commonly used in managing juvenile nasopharyngeal angiofibroma (JNA) to improve outcomes. However, few studies have evaluated how embolization patterns and vascular features affect prognosis. Methods A 15‐year retrospective review was performed on 44 patients with JNA undergoing surgery at one institution. Data included demographics, vascular supply, embolization techniques, surgical outcomes, and recurrence. Results Forty‐three patients underwent PVE. Most tumors were embolized transarterially (93.0%) using polyvinyl alcohol‐based agents (79.1%). The internal maxillary artery was most commonly embolized (93.0%). Internal carotid artery supply was present in 34.9%, and more than two vessels were embolized in 23.3%. Postembolization tumor blush occurred in 60.5%, with a median of 5% of the pre‐embolization blush remaining after embolization. Neither internal carotid involvement, number of vessels embolized, nor residual blush significantly impacted operative time, surgical outcomes, or recurrence. Conclusion With effective embolization, vascular complexity might not affect JNA resection outcomes. Multicenter studies are required to confirm those findings.

Abstract Few prospective benchmark studies exist to characterize the evolving contemporary real-world practice for peripheral T-cell lymphoma (PTCL). We report the patterns of first-line care and outcomes for 720 patients with systemic PTCL enrolled in 2 related prospective cohort studies, Lymphoma Epidemiology of Outcomes (LEO) from 2015 to 2020 and Molecular Epidemiology Resource (MER) from 2002 to 2015, both followed to 2024. The primary end points were event-free survival (EFS) and overall survival (OS) using Kaplan-Meier estimator and Cox regression model. Secondary end points included correlations of clinical and treatment factors with survival. The most common induction regimens were CHOP (cyclophosphamide, doxorubicin, vincristine, prednisone) based (70%), given as CHOP (36%), CHOP plus etoposide (23%), or CHOP-like plus novel agents (11.5%, including 5% BV-CHP [brentuximab plus cyclophosphamide, doxorubicin, and prednisone]). Consolidative autologous stem cell transplant was performed in 102 patients (14%). Within nodal PTCL, EFS and OS were adversely associated with International Prognostic Index 2 to 5, prognostic index for T-cell lymphoma score 1 to 4, and non–anaplastic large-cell lymphoma (ALCL) subtypes. Within LEO, which captured increasing first-line etoposide and brentuximab vedotin, adding etoposide to CHOP was associated with better OS in anaplastic lymphoma kinase-negative ALCL. BV-CHP showed a trend toward OS improvement in ALCL. Patients failing EFS6 and EFS24 had 5-year subsequent OS of 12% and 17%, respectively. The inferior outcomes in non-ALCL subtypes and patients failing EFS6 and EFS24 highlight unmet needs with CHOP-based induction, where clinical trials with targeted therapy should be prioritized. This trial was registered at www.clinicaltrials.gov as NCT02736357.

Abstract Background The ability of large language models (LLMs) to work collaboratively and screen studies in a systematic review (SR) is under-explored. Hence, we aimed to evaluate the effectiveness of LLMs in automating the process of screening in systematic reviews. Methods This is an observational study which included labeled data (title and abstracts) for five SRs. Originally, two reviewers screened the citations independently for eligibility. A third reviewer cross-checked each citation for quality assurance. GPT-4, Claude-3-Sonnet, and Gemini-Pro-1.0 were used using zero-shot chain-of-thought prompting. Collaborative approaches included (i): conflict resolution using benefit of the doubt, (ii) majority voting using an independent third LLM and (iii) conflict resolution using an informed third LLM. Performance was assessed using accuracy, precision for exclusion, and recall for inclusion. Work saved over samples (WSS) was computed to estimate the reduction in manual human effort. Results A total of 11300 articles were included in this study. The individual models, GPT-4, Claude-3-Sonnet, and Gemini-Pro-1.0 exhibited a high precision for exclusion, achieving 99.7%, 99.7%, and 99.2% and high recall for inclusion achieving 95.5%, 96.6% and 85.7%, respectively. However, the collaborative approach utilizing the two best-performing models (GPT-4 and Claude-3S) achieved an average precision of 99.9% and a recall of 98.5% (across all collaborative approaches). Furthermore, the proposed collaborative approach resulted in an average WSS of 63.5%, compared to the average WSS of 45.2% for individual models. Conversational LLM interactions showed a consistent pattern of results. Limitations This study was limited due to reliance on proprietary models, and evaluation on oncology datasets. Conclusion Evidence shows that collaborative LLMs enable efficient, high-performing screening in systematic reviews, supporting continuous evidence updates.

Abstract Background: Fatty Acid Synthase (FASN) is a key lipogenic enzyme co-regulated with HER2 and highly expressed in ER+ and HER2+ BC. Its targeting downregulates HER2 expression. Our preclinical studies revealed that FASN inhibition can sensitize or restore sensitivity to trastuzumab, paclitaxel and ET in HER2+ BC models. Denifanstat (deni, formerly TVB-2640) is a novel FASN inhibitor that demonstrated promising clinical activity and safety in a prior phase I trial as either monotherapy or in combination with paclitaxel. The primary objective of this study was to evaluate the objective tumor response rate (ORR) of deni plus trastuzumab (H) in combination with paclitaxel (T) or ET. Methods: Two independent, phase II clinical trials were initiated to assess the efficacy and safety of deni plus H in combination with T (Cohort A) or ET (Cohort B). Key inclusion criteria included HER2+ MBC resistant to HER2-directed therapy, measurable disease, unlimited ET, ≤6 prior chemotherapy or antibody drug conjugate regimens, and confirmation of HER2+ MBC on a pre-registration biopsy. Deni was administered 100 mg/m2 orally once daily. HP or H plus ET (fulvestrant or aromatase inhibitor) was administered at standard dose and schedule. Blood was collected on Cycle 1 Day 1 (C1D1), C1D8 and C2D1 for serum FASN analysis. An additional MBC tumor biopsy was collected on C2D1 for correlative studies. A 2-stage Simon design with a safety-run in was used to test the null hypothesis that the true ORR is at most 5% against the alternative it is at least 20%. With a sample size of 32 patients (pts) per cohort, if ≥4 responses are seen, this design has a 90% chance of rejecting the true ORR is <5% when the true ORR is ≥20% at a 0.10 level of significance. The decision to close both trials to enrollment early was multifactorial. Results: From August 2017 - February 2024, 33 pts with HER2+ MBC pre-registered, among which 17 were eligible and 16 were evaluable (15 pts in Cohort A and 1 pt in Cohort B). The most common reason for ineligibility was HER2-negative status on central review of the pre-registration biopsy. Median age was 57 years (range 35-80). All pts were non-Hispanic and 13 (81.3%) were White. Median prior lines of therapy was 5 (range 0 - 11). In Cohort A, there were 5 partial responses; thus, the primary endpoint was met with the ORR estimated to be 33.3% (90% CI: 14.2-57.7%). The median PFS time was 7.0 months (95 %CI: 3.7 - 11.3), and median OS was 25.7 months (95%CI: 10.2 - NE). No dose limiting toxicities were observed during the C1 safety run-in (6 pts). In Cohort A, 7 (46.7%) developed a grade 3 or 4 adverse event (AE) attributed to combination therapy. Grade ≥2 AEs regardless of attribution occurring in ≥20% of all pts included anemia, fatigue, neutropenia, palmar plantar erythrodysesthesia (PPE), and peripheral neuropathy. Treatment was discontinued due to progression (12; 80%) or AE (3; 20% - pneumonitis; neuropathy; PPE). In Cohort B, the pt maintained stable disease through 8 cycles with grade 3 ALT increase, and she remained alive 31.2 months post-registration. Median C1D1 FASN level was 32.7 ng/mL (IQR: 18.7 - 49.6 ng/mL). There was minimal association between C1D8 and C2D1 FASN levels and time to disease progression (C1D8 n=9, Spearman rank correlation coefficient (r s) = 0.040; C2D1 n=13, r s = -0.019). Analyses of changes in MBC tumor expression of FASN, phospho-AKT, and phospho-S6 are in progress. Conclusion: Deni combined with HP provided clinical antitumor activity in pts with HER2+ MBC resistant to trastuzumab. Expected paclitaxel-associated AEs were observed. Nearly half of pts experienced a grade 3 or 4 AE attributed to the combination therapy, and 20% stopped treatment due to AE. Further study of deni, H plus ET is necessary to draw safety and efficacy conclusions. Citation Format: T. C. Haddad, V. J. Suman, R. R. Roa, B. J. Ernst, R. Lupu, T. Vander Steen, M. H. Solanki, M.

Abstract Background: Two years of adjuvant abemaciclib plus endocrine therapy is approved and guideline-recommended in patients (pts) with HR+, HER2-, node-positive, early breast cancer (EBC) at high risk of recurrence. In initial real-world studies, the high rate (>85%) of treatment (tx) persistence beyond 3 months suggests that adjuvant abemaciclib is well-tolerated in routine clinical practice.1,2 Dose reductions were associated with higher persistence in prior studies and clinical trial data have shown that efficacy of abemaciclib was maintained with dose reductions. This study describes 6-month tx persistence and dosing patterns in pts with HR+, HER2-, node-positive EBC initiating abemaciclib 150 mg twice daily (BID). Methods: Retrospective data were accessed from the US de-identified Flatiron Health Research Database. Adults with HR+, HER2-, node-positive, EBC, who initiated abemaciclib 150 mg BID from Jan 2022-Jun 2024 were eligible and further characterized by ≥1 vs no dose reduction. Data cut-off was Dec 2024. Persistence rate was the proportion of pts on abemaciclib >6 months, allowing for ≤60-day medication gap within this period. Time to dose modifications and reasons for discontinuation (DC) were summarized. Subgroup analyses were conducted in pts confirmed as meeting the monarchE high-risk criteria (N2, N3, or N1 plus Grade 3 and/or tumor >5 cm). All analyses were descriptive. Results: Of 1063 eligible pts, median age was 56 years (IQR 47, 65). Most had N1 (48%) or N2 (34%) disease. Median follow-up was 17.5 months (IQR 11, 25). Tx persistence at 6 months was 75%. DC was mostly due to adverse events (AEs; 19%) and <1% due to recurrence. Approximately 50% of pts had ≥1 dose reduction. Persistence was 85% in pts with ≥1 dose reduction and 64% in pts with no dose reductions. 70% of pts who DC’d by 6 months did not have a dose reduction. Median time from start of abemaciclib to first dose change and/or hold was 49 days (IQR 23, 111). During the first 30 days of tx and Days 31-90, DCs due to AEs were lower in pts with dose reductions vs pts with no dose reductions (Table). Persistence and use of dose reductions were similar in pts confirmed as meeting the monarchE high-risk criteria. Conclusion: In US clinical practice, a majority (75%) who initiated adjuvant abemaciclib continued abemaciclib beyond 6 months. Tx persistence was higher among pts with dose reductions relative to those with no dose reductions, and rates of early DCs due to AEs were low in pts with dose reductions. Given that dose reductions in monarchE were not associated with reduced efficacy, these additional real-world data support the use of early dose modifications to improve tolerability and tx persistence for adjuvant abemaciclib in pts with high risk of recurrence.

Abstract Background: DNA methyltransferase (DNMT) isoforms 1, 3A and 3B are enzymes that regulate DNA methylation, controlling gene expression, chromatin stability and genetic imprinting. We have previously shown that DNMT3A protein expression in early triple negative breast cancer (TNBC) is associated with more aggressive clinicopathologic features (higher tumor grade, tumor proliferation and frequency of nodal metastases) and worse clinical outcomes in the absence of chemotherapy (Leon-Ferre et al, SABCS 2024). Pre-clinically, we have shown that DNMT3A protein expression predicts sensitivity to DNMT inhibitors (Yu J et al., J Clin Invest 2018), and that DNMT inhibitor treatment leads to downregulation of DNMT3A, enhanced expression of immune-related pathways, and halted tumor growth, particularly in combination with immunotherapy and paclitaxel. Methods: This is a phase 1, open-label, multicenter study evaluating the safety and recommended phase 2 dose (RP2D) of the oral DNMT inhibitor ASTX727 + paclitaxel + pembrolizumab in metastatic TNBC. ASTX727 is an oral fixed dose combination (FDC) tablet of 35 mg decitabine (active agent) and 100 mg cedazuridine (a cytidine deaminase inhibitor that prevents decitabine degradation in the bowel and liver, allowing oral delivery). The study consists of two parts: Part 1 is a dose-finding cohort, using a 3+3 design, with 5 dose levels (Table), and its primary objective is to determine the RP2D. Part 2 is an expansion cohort (n=6), with the primary objective to confirm tolerability of the regimen at the RP2D. Secondary objectives are to record the antitumor activity of the regimen, describe the AE profile, explore the association of baseline gene expression profiles with clinical benefit, and to evaluate impact of treatment on tumor and ctDNA methylation. Exploratory objectives will evaluate the association of baseline DNMT3A protein expression and antitumor activity, and the impact of treatment on the tumor and peripheral blood immune phenotype. Eligible patients are adults 18 years or older with metastatic TNBC (ER/PR ≤10%, and HER2-negative per ASCO/CAP guidelines), independent of PD-L1 expression. Patients are allowed to have received 0-3 prior lines of systemic therapy in the metastatic setting, including prior immune checkpoint inhibitors in the early and/or metastatic settings. Patients must be eligible for taxanes and have adequate organ and bone marrow function. Patients with treated brain metastases are eligible if previously treated without evidence of progression after 4 weeks. Leptomeningeal carcinomatosis is not allowed. Patients must have an ECOG performance status of ≤2 and have no gastrointestinal disorders impacting absorption of oral medications. As of June 20, 2025, the study is enrolling patients, with 10 patients dosed in the dose-finding phase. Citation Format: R. Leon-Ferre, D. M. Zahrieh, P. P. Advani, D. Quiroga, K. V. Giridhar, P. J.
