Abstract Background It was reported that patients with Non-Alcoholic Fatty Liver Disease (NAFLD) were at increased risk of contracting severe infections requiring hospitalization which could end up with sepsis. However, data regarding the impact of comorbid NAFLD on the in-hospital outcomes of sepsis admission is scarce. Methods This nationwide retrospective observational study included 21,057,911 adult patients who were admitted into hospitals in the United States between 2000 and 2019 with a primary discharge diagnosis of sepsis. These patients were categorized according to the presence or absence of comorbid NAFLD. The twenty-year trend of nationwide NAFLD prevalence among sepsis inpatients was elucidated. Multivariate logistic regression analysis was used to analyze NAFLD's impact on in-hospital outcomes of sepsis. Results In the twenty-year study period, the prevalence of NALFD among sepsis inpatients trended up from 1.2% in 2000 to 4.2 % in 2019. While sepsis mortality had trended down, comorbid NAFLD in sepsis patients was consistently associated with a higher adjusted in-hospital all-cause mortality rate (adjusted odds ratio (OR), 1.45; 95% confidence interval (CI), 1.42-1.48), higher odds of developing septic shock, and multi-organ dysfunctions (including cardiovascular-, renal-, and hepatic dysfunction). They were more likely to be discharged to another acute hospital. The length of stay of sepsis patients with NAFLD who died in the hospital was significantly shorter than those without NAFLD. Conclusions Comorbid NAFLD is associated with higher in-hospital all-cause mortality and worse clinical outcomes in sepsis inpatients. Addressing this rising epidemic will be of paramount importance to improve sepsis in-hospital outcomes.
SOR-CART-MM-001 Study: A Phase I, Open-Label, Dose-Escalation, Pharmacokinetic, and Pharmacodynamic Study of Safety and Efficacy of CAR2 Anti-CD38 A2 CAR-T Cells in Patients with Relapsed or Refractory Multiple Myeloma (RRMM)
Background: B-cell maturation antigen (BCMA) directed chimeric antigen receptor (CAR-) T cells, show high response rates in patients with highly refractory and heavily treated myeloma, and have become a standard treatment in this setting. The durability of these responses, however, has been limited with few long term remissions. One approach to potentially improve CAR T outcome is to direct these cells to alternative targets such as CD38 almost universally expressed on malignant plasma cells. In this open-label phase I multi-institutional study we explored the efficacy and safety of CAR2 anti-CD38 A2 CAR-T cells in patients with RRMM. Methods: The SOR-CART-MM-001 study was a multicenter, open-label, “3+3” dose-escalation, phase 1b trial of a single administration of a fully human antibody with lambda light chain generated by transduction of activated T cells with an anti-CD38 A2 CAR expressing retroviral vector. A single dose of CAR2 Anti-CD38 CAR-T cells was administered 2 days post lymphodepletion with single-agent cyclophosphamide 1.5 g/m 2. The primary endpoint was determination of the maximum tolerated dose (MTD) assessed by the occurrence of treatment-emergent dose-limiting toxicities during the 28-day treatment period in the dose-escalation phase of the study. Dosing was divided into three cohorts ranging from 1 × 10 5 cells/kg (Cohort 1) to 1 × 10 7 cells/kg (Cohort 3). Circulating CAR-T cells were measured at different timepoints post infusion. Key eligibility criteria included ≥3 lines of therapy with prior proteasome inhibitor, immunomodulatory IMID drug or daratumumab exposure, measurable and progressive MM per International Myeloma Working Group criteria and ECOG ≤ 2. Results: Between March 2018 and March 2022, 9 patients were enrolled and assigned to each of the three Cohorts. Patient demographics and baseline characteristics are described in Table 1. Hematologic toxicity was the most common treatment emergent adverse event experienced (6/9, 66.7%), all Grade 3 or Grade 4. All cytopenias recovered in 21 days in subjects treated with no more than MTD. Two subjects within Cohort 3 exhibited mild cytokine release syndrome (CRS) (Grade 1 and 2) with one of these two subjects also developing mild neurotoxicity (Grade 2). No CRS or neurotoxicity was observed at either of the lower dose levels. Two serious adverse events (SAEs) were reported: Klebsiella sepsis 60 days after treatment that recovered in 4 days after antibiotics and muscle weakness at 24 days after treatment that received within 1 day without treatment and neither were deemed related to the study medication. The first 2 patients in Cohort 3 met dose limiting toxicity (DLT) criteria after treatment due to grade 3 hematological toxicity and the next lower dose 1 x 10 6 cells/kg (Cohort 2) became the MTD. Pharmacokinetic data showed the percentage of the detectable circulating CAR-T cells in any subject at any time point was low with many showing no detectable cells. 4 deaths were reported after the end of the study period, and none were considered related to the investigated CAR-T cells (3 due to progression and one due to COVID-19). Overall, a total of 3 patients had a partial response (PR) and 3 patients had stable disease (SD) across 3 dose levels. PR constituted the best response in the study and the durations of objective clinical responses were each less than 3 months. These treatment responses are summarized in Table 2. Conclusion: This phase I trial demonstrated that CAR2 anti-CD38 A2 CAR-T cells were generally well tolerated at the Cohort 2 (MTD) dose and demonstrated objective though short responses even in patients progressing after daratumumab and belantamab mafodotin. More clinical studies are needed to optimize the efficacy and tolerability of CAR-T cell therapies for patients with RRMM. This study was completed, and no more patients will be enrolled. DART-RRMM-101 is a phase 1b, open-label, dose-escalation study ongoing to assess allogeneic Anti-CD38 A2 Dimeric Antigen Receptor T Cells in RRMM (ClinicalTrials: NCT05007418).
Abstract A042: Community advisory board members’ perspectives on genetic literacy and patient-caregiver communication of prognostic genomics for localized prostate cancer
Abstract Background: The National Comprehensive Cancer Network (NCCN) recommends the use of tissue-based genetic tests, such as Decipher, Prolaris, and Confirm mdx for localized prostate cancer, to help patients and caregivers make more informed treatment decisions at the time of diagnosis. However, while much enthusiasm currently exists for the burgeoning field of genomic medicine, prostate cancer disparities continue to persist in underserved communities despite the existence of evidence-based treatment guidelines. Methods: A diverse 15-member Community Advisory Board (CAB) representing rural and urban communities in Duval County, Florida were recruited from May to June 2023, to build a community-academic partnership, for the development and implementation of a genetic literacy patient-caregiver educational intervention for localized prostate cancer. The 15-member CAB was divided into groups of 5 for focus group discussions. Qualitative and quantitative data from CAB members were integrated to gain better understanding of the facilitators and barriers for prostate cancer genetic literacy in underserved communities. Results: The thematic analysis reveals several key themes related to prostate cancer, screening, treatment, and genetics. These themes reflect the diverse perspectives and experiences of the CAB members regarding prostate cancer, ranging from personal anecdotes to broader societal issues. Participants expressed thoughts related to fear, lack of knowledge, cultural beliefs, and access to healthcare. The discussion on prostate cancer and tissue based genetic testing highlighted the complexities surrounding prostate cancer and the need for further education, awareness, and access to affordable healthcare for all individuals at risk. Conclusion: CAB members emphasized the importance of improving access to information, promoting education, and addressing cultural barriers to ensure that individuals are informed about available options for prostate cancer diagnosis and treatment.

Efficacy and Safety of Twice-Daily versus Three-Times Daily Saquinavir Soft Gelatin Capsules as Part of Triple Combination Therapy for HIV-1 Infection
Objective The objective of this study was to determine whether a triple therapy regimen incorporating twice-daily saquinavir is as effective as a three-times daily regimen. Methods This was an open-label, Phase III, multicentre, 48-week study involving 837 HIV-1-infected patients randomised to one of the following: saquinavir soft gel capsule (SGC) 1200 mg three-times daily, plus two nucleoside reverse transcriptase inhibitors (NRTIs) (arm A); saquinavir SGC 1600 mg twice-daily, plus two NRTIs (arm B); saquinavir SGC 1200 mg twice-daily and nelfinavir 1250 mg twice-daily, plus a single NRTI (arm C). The primary outcome measure was the virological response in arm A versus B and in arm A versus C with respect to the percentage of patients whose plasma HIV-1 RNA levels fell below the level of quantification for the Amplicor assay (<400 copies/ml) at weeks 24 and 48. Results At 48 weeks, the percentage of patients with plasma HIV-1 RNA levels <400 copies/ml was 47.1% (arm A), 45.3% (arm B) and 42.7% (arm C) in the intention-to-treat analysis. The treatment difference between arm B–arm A was -1.8% (95% confidence intervals -10.1, 6.5) and for arm C–arm A was -4.5% (95% confidence intervals -12.7, 3.7) in the intention-to-treat analysis. These differences fell within the maximum allowable difference (±12%) for arm B compared with arm A. At week 24, the percentage of patients with HIV-1 RNA levels <400 copies/ml was 59.6% (arm A), 57.6% (arm B) and 51.3% (arm C). Conclusions A twice-daily triple therapy regimen incorporating saquinavir SGC plus two NRTIs was of equivalent efficacy to the three-times daily regimen studied. All regimens were generally well tolerated.
