OBJECTIVES/SPECIFIC AIMS: Understand the association between ADI and completion of preventative cancer screening and high risk behaviors -Identify how to operationalize ADI in clinical settings to assist care teams and improve overall care delivery. METHODS/STUDY POPULATION: Aim 1: Paneled Mayo Clinic patients living in MN, IA, or WI Aim 2: BRFSS survey respondents from MN, IA, or WI Aim. 3: Community health officials and Mayo Clinic care teams. RESULTS/ANTICIPATED RESULTS: We anticipate that areas with greater composite deprivation will have lower completion rates of cancer screening and higher risk behaviors. DISCUSSION/SIGNIFICANCE OF IMPACT: No single body of work has illustrated how ADI relates to completion of preventative cancer screening and high-risk behaviors. Due to the limited research focused on area deprivation and behavioral health, our work will identify some of the first national hot spots with high deprivation and high-risk behaviors. Additionally, this is one of the first studies describing spatial variation in health outcomes for Mayo Clinic patients. Understanding the association between ADI and patient adherence to preventative screening will allow us to support care teams in providing personalized and sustainable care for patients living in areas of high deprivation. The strength and novelty of this project is in the utility of the mixed methods design, which provides a more complete understanding of geographic disparities and a unique perspective to patient care, a perspective that is not portrayed in existing literature.

OBJECTIVES/GOALS: The FDA allows physicians to request clinical use of investigational drugs, biologics, and devices for patients with no satisfactory treatment options through a pathway called Expanded Access (EA). TEAMSS (Transforming Expanded Access to Maximize Support and Study) sought to examine single-patient cases to better characterize these patients. METHODS/STUDY POPULATION: We prospectively collected data on requests for single-patient EA at any one of the four collaborating TEAMSS institutions (Duke University, University of Rochester, University of Michigan, and University of Texas Southwestern) between September 1, 2021 and February 28, 2023. Regulatory and health records were reviewed for past cases that occurred between June 1, 2018 and August 31, 2021. Descriptive statistics were performed on data from the submission process, the patient demographics, the indication for treatment, and patient health status over time. RESULTS/ANTICIPATED RESULTS: The patient population was representative with respect to the largest racial groups (69.3% White / 13.0% Black or African American) and legal sex (51.3% male / 48.7% female). All ages were represented, with overrepresentation of those 60-70 years old (16.8%) and under 10 (14.8%). Patients were most often treated for infectious diseases (44.2%) or oncologic conditions (39.0%). Those who received more than one dose stayed on treatment for 76 days (median) and up to 1427 days (maximum). At the end of study, 53.9% had completed treatment as planned, moved to commercial product, or continued treatment. Death, disease progression, or failure to respond occurred for 31.9% of patients. DISCUSSION/SIGNIFICANCE: The population that receives Expanded access treatments is heterogeneous in both demographics and medical conditions. Some successful treatments are continued for years. Many patients complete their treatment, and a minority experience death or disease progression during treatment.

OBJECTIVES/GOALS: Mayo Clinic (MC) launched the Rapid Activation Trial (RAT) pilot program in 2022 to expedite the activation of high priority and high impact clinical trials. The objective was to develop a process for rapid activation through robust screening, prioritization, and project management (PM) support. METHODS/STUDY POPULATION: The project team developed a robust screening and approval process for the RAT program using a combination of an objective scoring tool (based on strategic priorities) and a diverse selection committee to screen and approve eligible trials. Sponsors had to commit to RAT program timelines. Upon approval, trials were prioritized at the highest level within each business unit involved in the activation process. The number of trials approved annually were limited to 8 to manage volume and facilitate seamless prioritization with an activation timeline goal of 6 weeks. Project management support for RAT program focused on financial, regulatory, logistical, and operational elements to open trials expeditiously. RESULTS/ANTICIPATED RESULTS: In 2022, thirteen (13) applications were received and eight (8) were approved by the RAT selection committee. The approved trials activated with a median open to enrollment time of 6.4 weeks from engaging with business units. They also aligned closely with organization’s strategic priorities, including but not limited to Investigator Initiated Trials, Multi-Site protocols, IND/IDE protocols, Rare Diseases, First in Human and Commercialization potential trials. PI and study team feedback was positive. In 2023, the RAT program was renewed due to the pilot’s significant success in 2022. The goal is to open 10 trials and 5 have been activated by the end of Q3, 2023 with a median timeline of 6 weeks. DISCUSSION/SIGNIFICANCE: Rapid activation of high priority and high impact clinical trials enables an organization to strategically prioritize and open complex clinical trials. This allows the delivery of innovative, timely cures to patients in an expeditious timeline.

The efficient and effective movement of research into practice is acknowledged as crucial to improving population health and assuring return on investment in healthcare research. The National Center for Advancing Translational Science which sponsors Clinical and Translational Science Awards (CTSA) recognizes that dissemination and implementation (D&I) sciences have matured over the last 15 years and are central to its goals to shift academic health institutions to better align with this reality. In 2016, the CTSA Collaboration and Engagement Domain Task Force chartered a D&I Science Workgroup to explore the role of D&I sciences across the translational research spectrum. This special communication discusses the conceptual distinctions and purposes of dissemination, implementation, and translational sciences. We propose an integrated framework and provide real-world examples for articulating the role of D&I sciences within and across all of the translational research spectrum. The framework’s major proposition is that it situates D&I sciences as targeted “sub-sciences” of translational science to be used by CTSAs, and others, to identify and investigate coherent strategies for more routinely and proactively accelerating research translation. The framework highlights the importance of D&I thought leaders in extending D&I principles to all research stages.

We used Cerner Real-World Data™, representing hospital admission records from 2020, to examine patients with co-occurring sickle cell disease and COVID-19 by discharge disposition grouped as death/hospice versus transfers to other facilities, returned home, or left against medical advice. Among the death/hospice group, we found older age and higher rates of congestive heart failure and diabetes. There were also significant differences in tachypnea, mechanical ventilation, minimum O2 saturation, and length of stay with higher rates in the death/hospice group. Awareness of such factors and associated mortality risks for this population may aid in patient care.

The United States Government (USG) public-private partnership “Accelerating COVID-19 Treatment Interventions and Vaccines” (ACTIV) was launched to identify safe, effective therapeutics to treat patients with Coronavirus Disease 2019 (COVID-19) and prevent hospitalization, progression of disease, and death. Eleven original master protocols were developed by ACTIV, and thirty-seven therapeutic agents entered evaluation for treatment benefit. Challenges encountered during trial implementation led to innovations enabling initiation and enrollment of over 26,000 participants in the trials. While only two ACTIV trials continue to enroll, the recommendations here reflect information from all the trials as of May 2023. We review clinical trial implementation challenges and corresponding lessons learned to inform future therapeutic clinical trials implemented in response to a public health emergency and the conduct of complex clinical trials during “peacetime,” as well.

OBJECTIVES/SPECIFIC AIMS: Immune cells within the tumor microenvironment (TME) play an important role in the development and progression of non-small cell lung cancer (NSCLC). However, data evaluating the impact of individual immune cell types on NSCLC outcomes is limited and often conflicting. We performed a meta-analysis of existing data and used The Cancer Genome Atlas (TCGA) to evaluate the effect of several immune cells on surgical outcomes of stage I-IIIA NSCLC. METHODS/STUDY POPULATION: PubMed was searched to identify eligible studies evaluating survival of surgically resected stage I-IIIA NSCLC patients according to immune cell infiltration. Meta-analysis was performed using a linear mixed-effects model to determine overall, disease specific and progression free survival. We then used a similar patient subset found in the TCGA to validate the meta-analysis findings. For the TCGA analysis, sample-specific scores for different immune cells were computed via xCell using level three RNAseq data. After stratifying the cohort by histologic subtype, the association between each cell type and survival was assessed via Cox Regression, while adjusting for stage, gender and smoking status. RESULTS/ANTICIPATED RESULTS: From the meta-analysis (37 articles eligible; N = 8,162 patients), high levels of CD20+ B cells (hazard ratio [HR]: 0.36, 95% confidence interval [CI]: 0.15-0.85), natural killer (NK) cells (HR: 0.64, 95% CI: 0.41-1.0), and dendritic cells (0.34, 95% CI: 0.13-0.84) were significantly associated with better overall survival (OS); T regulatory cells (HR: 1.85, 95% CI: 1.35-2.54) were associated with worst OS. High CD8+ T cell infiltrates were associated with improved disease-free survival (DFS; HR: 0.85, 95% CI 0.73-0.99), while CD68+ macrophages (HR> 2.83, 95% CI: 1.28-6.24) were associated with worst DFS. In the TCGA cohort, lung adenocarcinomas rich in CD4 T cells, CD8 T cells, B cells, and NK cells were associated with improved OS in unadjusted analysis. In adjusted analysis, only NK cells were associated with improved OS (HR: 0.82, 95% CI: 0.69-0.98). There was no significant association of any immune cell type for DFS in lung adenocarcinomas and with both OS and DFS in Squamous Cell Lung Cancers (p>0.05 for all comparisons). DISCUSSION/SIGNIFICANCE OF IMPACT: The presence of tumor infiltration by specific immune cell subsets may potentially predict survival outcomes in resected stage I-III NSCLC patients. However, the impact of immune cells may not be similar in all histologic types and after adjusting for important clinical confounders.

OBJECTIVES/GOALS: To establish and develop a high-level, dynamic, and self-sustainable Translational Science – research center in Colombia that promotes and articulates collaborative participation among different disciplines at Universidad de La Sabana to generate impactful solutions in health to transfer the knowledge to the local community. METHODS/STUDY POPULATION: With the support of core units of the University, internal funding was given for the establishment of the Research Center. An internal call was performed for recruiting researchers for multiple disciplines interested in joining the UCTS. After the researchers were selected, training of the research community in translational science and funding acquisition was performed towards the objective of interdisciplinary projects with impact in the local community. Project management strategies have been used for the follow-up of the advancements of the implementation of the UCTS. Operational structure and business plan for future self-sustainability are being designed. UCTS is proposed as an articulating party among different actors in clinics, research, and industry, for science and funding management. RESULTS/ANTICIPATED RESULTS: As an starting point, 8 research groups of different disciplines of the University have been integrated with the UCTS, increasing the research capacity in translational science. Internal administrative processes have been articulated within the institution and unified processes for international grants applications have been established in order to optimize the funding acquisition and management. Training programs for the research community, and community engagement activities have been offered as well. Networking relationships have been strengthened among the researchers enhancing international collaborations. Novel research projects are being designed towards real solutions in health for the local community, promoting the transference of knowledge from the benchside to the community. DISCUSSION/SIGNIFICANCE: The implementation of the UCTS led to the integration of disciplines within the University, towards new research projects with common interests for the local community. It has been an enriched experience using the project management approach, fulfilling a huge milestone for the University, aligned with the internal strategic priorities

OBJECTIVES/SPECIFIC AIMS: Aim 1: To evaluate whether psoas muscle size on CT imaging can be used as univariate predictor for increased risk of morbidity and mortality in trauma patients 65 years or older with rib fractures. Primary outcomes will be 30 day mortality. Secondary outcomes will include length of stay, 30 day readmission rate, need for operative/procedural intervention, ICU days, ventilator days, discharge to rehabilitation. Aim 2: An eventual goal of the project will be to use the results of the single variable psoas size study to inform the development of a predictive model for readmission rate in this population based on clinical variables present at admission. METHODS/STUDY POPULATION: This retrospective cohort study will utilize the Maine Trauma Registry to conduct a database review for all persons 65 years of age and older admitted to Maine Medical Center between January 1, 2015 and December 31, 2017 with rib fracture as diagnosed by CT imaging. Psoas caliber will be measured on admission CT. Patient outcomes will be assessed via EMR review. RESULTS/ANTICIPATED RESULTS: Anticipate finding a relationship between decreased psoas caliber and increase in 30 day mortality and post trauma complications. DISCUSSION/SIGNIFICANCE OF IMPACT: If a relationship is demonstrated between decreased psoas caliber and poor outcomes in elderly patients with rib fractures, this early indicator could be used to identify those patients at most risk, for whom targeted interventions may make the greatest difference. Knowing a measure of frailty could also help guide goals of care discussions, because it would allow clinicians to have a more detailed understanding of a patient’s baseline. Those patients identified as frail could be admitted to an ICU level of care and more closely monitored and treated. Alternatively, some frail patients and their families may choose to focus more on comfort and quality of life after achieving a better understanding of a patient’s frailty and risk, changing the direction of care provided. Being able to identify the higher risk patients with an objective measure would allow clinicians to provide more personalized medicine.

OBJECTIVES/GOALS: High turnover rates of clinical trials staff pose obstacles to the quality and efficiency of conducting clinical trials. We have explored alternative staffing models to address these translational barriers and to improve the financial viability and return on investment of a centralized clinical trials office. METHODS/STUDY POPULATION: Implementation of an alternative clinical trials staffing model that leveraged burnout rates in clinical service areas by hiring APPs, RNs, EMTs, OTs and PTs in tandem with traditional CRAs/CRCs. Financial modelling of employing higher salaried clinical professionals was analyzed with regards to greater staff retention, trials efficiency, and operational cost savings. RESULTS/ANTICIPATED RESULTS: Since 2014, 30 of 51 (59%) staff left the clinical trials office with 49% of these leaving prior to 2 years employment. Using average local CRCII compensation values, the costs associated with these transient staff amounted to $2.51 million (i.e., recruitment, replacement, and training). Models of staffing that replace 2 CRAs, 2 CRCIs and 2 CRCIIs with an RN, APP, CRCI and 3 CRAs increases compensation by 24.1%. This increase, however, is offset by greater workload capacity, retention, and more efficient trials operations. In addition, revenue generating PI clinical activity is sustained by employing credentialed APPs for study visits. DISCUSSION/SIGNIFICANCE: Long-term financial savings and greater clinical trial operational efficiency may be accomplished by seeking clinical professionals looking for alternative opportunities with greater work-life balance while leveraging their advanced clinical skills and licensing.

OBJECTIVES/SPECIFIC AIMS: Projected to soon become the most prevalent cause of End-Stage Liver Disease, the frequency of Non-Alcoholic Fatty Liver Disease (NAFLD) has been rising in the US community. However, studies on NAFLD among inpatients are lacking. Aims: To report the 1) prevalence and trends, 2) outcomes of NAFLD associated hospitalizations in the US. METHODS/STUDY POPULATION: NAFLD cases were identified in the National Inpatient Sample (2007-2014) with ICD-9-CM codes, and the prevalence and trends over the 8-year period were calculated among different demographic groups. After excluding secondary causes of hepatic fat accumulation from the NAFLD cohorts (n = 210,660), the impact of sex, race, and region on outcomes (mortality, discharge disposition, length of stay [LOS] and cost) of NAFLD was computed with generalized estimating equations (SAS 9.4). RESULTS/ANTICIPATED RESULTS: Admissions with NAFLD tripled from 2007-2014 at an average rate of 79/100,000 hospitalizations/year (p-value < 0.0001), with a larger rate of increase among males vs. females (83/100,000 vs. 75/100,000), Hispanics vs. Whites vs. Blacks (107/100,000 vs. 80/100,000 vs. 48/100,000), and governmental-/un-insured patients vs. privately-insured (94/100,000 vs. 74/100,000). Males had higher mortality, LOS and cost than females. Blacks had longer LOS and poorer discharge destination than Whites; while Hispanics and Asians incurred higher cost than Whites. Uninsured patients had higher mortality, longer LOS and poorer discharge disposition than the privately-insured. DISCUSSION/SIGNIFICANCE OF IMPACT: Hospitalizations with NAFLD is rapidly increasing in the US, with a disproportionately higher burden among certain demographic groups. Measures are required to arrest this ominous trend and to eliminate the disparities in outcome among patients hospitalized with NAFLD.

OBJECTIVES/GOALS: In a 2022 NASEM Report, “… successful inclusion of underrepresented populations in research is investing in diverse research teams to enhance congruence and to optimize recruitment and retention success.” Thus, academic research institutions must provide safe, respectful and inclusive work environments to support diverse research teams. METHODS/STUDY POPULATION: Resources, policies and protocols related to disruptive research participants have not been well articulated at our institution. Given this dearth of information, we launched a new initiative across our CTSA, IRB, Office of General Counsel and Department of Population Health. The multipronged approach includes: 1) Conduct a scoping review of published and gray literature to identify best practices, trainings and resources to mitigate discrimination, harassment of research team members; 2) Co-develop new institutional policies and procedures to ensure safety and respect for both research staff and participants; 3) Develop an online training on research team field and workplace safety; and 4) Widely disseminate policies and resources to address the overall gap in academic research. RESULTS/ANTICIPATED RESULTS: Our ongoing scoping review has shown that here is an overall lack of information on bias, discrimination and harassment perpetrated by research participants towards research teams. Based on our activities, new Human Research Protection policies were launched. These include defining what disruptive participant behavior in research is, the introduction of a Statement on the Conduct of Participants in Research Studies, and steps study teams may implement to manage disruptive behavior initiated by a research participate. Next steps include the development of training resources for study teams on the new policies and to introduce de-escalation and situational awareness strategies and trainings. DISCUSSION/SIGNIFICANCE: As research teams become increasingly diverse, there is a need to better support them and ensure that the research field and work settings are safe, inclusive environments with articulated policies that mitigate/prevent discrimination, bias and harassment perpetrated by study participants.

OBJECTIVES/SPECIFIC AIMS: The objective of this study was to reconstruct patient-specific distal airway patterns at the tissue- and single-cell resolution and develop personalized distal airway models based on utilization of patient-derived DABCs and autologous region-specific stromal cells. METHODS/STUDY POPULATION: Patient-specific distal airway units, containing parental small bronchiole (<2 mm in diameter, >12th generation) and daughter airway branches, including pre-terminal/terminal bronchioles, leading to alveoli (3-7 units/lung), were dissected. Epithelial and stromal cells were isolated from these units and processed for ddSeq single-cell RNA-sequencing (n=6 samples). Autologous DABCs and stromal cells were isolated, propagated, biobanked, and used for establishment of patient-specific distal airway models (3D-organoids and air-liquid interface-based airway wall model; n=10 samples). Region-specific tissue patterns were evaluated using immunofluorescence and laser-capture microdissection (LCM; n=6 samples). RESULTS/ANTICIPATED RESULTS: Single-cell-based human distal airway transcriptome map (constructed based on the analysis of >6,500 distal airway cells obtained from 6 subjects) identified physiological and COPD-relevant distal airway differentiation patterns, including distal airway-specific secretory phenotype (DASP) characterized with high expression of secretoglobins 3A2 and 3A1, surfactant proteins SFTPB and SFTPA2, and mucin 1, unique signatures of DABCs, and stromal (fibroblasts, smooth muscle, endothelial cell subpopulations) and immune (macrophage, T cells, B cell, mast cells). Immunofluorescence analysis and LCM confirmed distribution of cell type-specific markers with differential expression patterns of DABC and DASP signatures. Patient-derived DABC-stromal co-culture models reproduced 3 regenerative patterns: 1) physiological (high DABC-clonogenic potency, establishment of polarized differentiated organoids and DASP-expressing epithelia); 2) hypo-regenerative (failure of DABCs to form clones, spheres and mechanically stable differentiated epithelial barrier); and 3) hyperplastic (generation of DABC hyperplasia accompanied in some COPD samples by mucous-cell hyperplasia mimicking in vivo remodeling patterns). DISCUSSION/SIGNIFICANCE OF IMPACT: Patient-specific maps and models of distal airway regeneration patterns have been established in this study, which can be used to identify candidate pathways that mediate disease-relevant airway remodeling and potentially utilized as pre-clinical platforms for developing personalized therapeutic approaches to suppress the progression of distal airway remodeling in chronic lung diseases, including COPD.

OBJECTIVES/GOALS: A strategic initiative of Mayo Clinic is to decrease clinical trial activation timelines by 25% from 2022 levels. The team’s goal is to streamline activation via parallel processing, improved collaboration with business units, project manager facilitation, and early study coordinator involvement. METHODS/STUDY POPULATION: The workgroup targeted industry trials, focusing on key financial, regulatory, and operational elements. Current state process workflows and pain points were prepared and opportunities for concurrent activities or automation identified. The scope of the project manager role from the Office of Clinical Trials was extended to guide each activation team, who have varying levels of experience, to maintain timelines until the trial is opened. Coordinators responsible for study conduct engaged in key operational discussions earlier to ensure the trial will be run successfully. A Pilot program is utilizing the identified concurrent activities, project manager support, and earlier coordinator involvement to gauge effectiveness of the proposed solutions. RESULTS/ANTICIPATED RESULTS: The goal is for 120 industry clinical trials to join the Pilot program and to open enrollment in less than 30 weeks from being document ready. As of Q3 2023, 109 clinical trials across multiple Mayo sites have enrolled in the pilot. Thirty-five (85 percent) of 41 Pilot trials have opened to enrollment and have met the goal, with a median timeline of 24 weeks. Twenty-one (21) trials opened to enrollment in Q3 2023 with a median timeline of 23 weeks, representing 24% of all industry clinical trials opened that quarter. Opening trials and monitoring is ongoing and PI and study team feedback is positive. DISCUSSION/SIGNIFICANCE: Using a team-based approach, we identified key areas for optimization and parallel processing. The solution reduces trial activation timelines, increases patient access to experimental therapies, and has been positively received by study staff. Future projects will focus on enterprise implementation, optimization, and automation.
