OBJECTIVES/GOALS: Physicians can request the clinical use of investigational products for their patients through an FDA pathway called Expanded Access (EA). Most evaluations of EA focus on the FDA submission only. We sought to evaluate these requests through the full academic medical center process. METHODS/STUDY POPULATION: Through the Transforming Expanded Access to Maximize Support and Study grant, we reviewed regulatory records for single-patient EA requests at four institutions (Duke University, University of Rochester, University of Michigan, and University of Texas Southwestern) which occurred between June 1, 2021 and February 28, 2023. Key data was collected, including the investigational product requested, submission and approval dates, urgency of request, and indication for treatment. Descriptive statistics were performed with Microsoft Excel. RESULTS/ANTICIPATED RESULTS: A total of 405 EA requests were identified, of which 319 (78.8%) were for drugs, 59 (14.6%) for biologics, and 27 (6.7%) for medical devices. The majority were characterized as non-emergency (60.7%), but the proportion of emergency to non-emergency cases varied considerably when stratified by year, with a peak in emergency cases in 2020. The most common products included therapies for COVID-19 and Mpox. Median time to obtain all approvals for treatment was 7 days for emergency cases and 28 days for non-emergency. The FDA review took the least time, with a median of 1 day in non-emergency cases. Full board approval from an institutional review board in non-emergency cases was 7 days. DISCUSSION/SIGNIFICANCE: These results generally align with previous reports on EA submissions received by the FDA. The timelines for the EA process represent an important benchmark both for treatment planning and institutional improvement.

Objectives/Goals: This review examined if sleep duration is associated with established Alzheimer’s disease (AD) fluid biomarkers, such as amyloid-β peptides (Aβ40 and Aβ42), total-tau (t-tau), phosphorylated tau (p-tau181 and p-tau217), neurofilament light chain (NfL), and glial fibrillary acidic protein (GFAP). Methods/Study Population: We searched PubMed, CINAHL, and SCOPUS through September 15, 2024, using keywords and appropriate subject headings related to AD, fluid biomarkers, and sleep. The search was developed and conducted in collaboration with a medical librarian. We also searched Google Scholar and screened the reference lists of relevant reviews. Two independent reviewers screened 1,657 peer-reviewed articles, of which 21 met the inclusion criteria (14 with biomarkers measured in cerebrospinal fluid [CSF] and 7 in blood). Two review authors independently extracted study details from included articles using a standardized data extraction template. Results/Anticipated Results: Sample sizes ranged from 18 to 4,712 participants. Sleep duration was assessed using self-reported measures in 8 studies and objective measures in 13. For the 14 studies using CSF biomarkers, lower Aβ42 (3/14), Aβ40 (1/14), or the ratio (1/14) were associated with either short or long sleep duration; t-tau (3/14) and p-tau181 (4/14) levels were mostly associated with short sleep. For the 7 blood-based biomarker studies, Aβ42 (2/7), Aβ40 (2/7), and the ratio (3/7) had mixed results with either short or long sleep. T-tau (1/7) and p-tau181 (1/7) levels were associated with long sleep; NfL (2/7) was associated with both short and long sleep. Six studies reported nonlinear relationships, with both short and long sleep associated with unfavorable biomarker profiles. None of the studies investigated p-tau 217 or GFAP. Discussion/Significance of Impact: Our results suggest that the relationship between sleep duration and AD fluid biomarkers is very complex, and it highlights the importance of sleep in AD risk assessment and prevention. The inconsistency in findings stresses the need for standardized study design and measurement methods to clarify causality and inform clinical guidelines.

OBJECTIVES/GOALS: There are two objectives: 1) To identify healthcare providers’ (HCP) barriers and potential solutions towards rural adolescents’ access to mental healthcare. Healthcare providers include pharmacists, physicians, and mental healthcare providers (MHPs). 2) To identify rural high schoolers’ barriers and potential solutions towards access to mental healthcare. METHODS/STUDY POPULATION: Fifteen HCPs will be recruited via email listserv and the snowball method. Perceived barriers of rural adolescents, personal barriers, current practices to address mental health in adolescents, and preferred solutions will be discussed. Twenty student and parent dyads will be recruited using fliers in school systems and will be interviewed individually outside of class time on school grounds or over the phone. Barriers to care and preferred solutions will be discussed. All interviews will be semi-structured, recorded, conducted in person or over the phone, and last for 30 minutes to an hour. Compensation will be $25 for students and parents each, $50 for pharmacists and mental health providers and $100 for physicians. Thematic qualitative data analysis will be performed using Atlas.ti software. RESULTS/ANTICIPATED RESULTS: Data collection is ongoing. Anticipated results for barriers include absence of mental healthcare providers in rural areas, inability to access mental healthcare providers further away, stigma towards mental healthcare, and lack of knowledge of mental health conditions and treatment. Anticipated results for potential solutions may include promoting mobile applications to assist with telehealth and self-care. Other solutions may be collaboration among rural healthcare providers for adolescents with mental health conditions. Preferred solutions may also include pharmacists disseminating knowledge to rural adolescents and their parents or referrals to mental healthcare providers. DISCUSSION/SIGNIFICANCE OF IMPACT: This project will identify barriers and solutions to access to mental healthcare among rural adolescents. These solutions can then be applied towards the creation of programs that address salient issues within rural communities with a greater chance of uptake and use so that rates of depression and suicide will decrease. CONFLICT OF INTEREST DESCRIPTION: Funding through UAB TL1 award.

Through a series of example research studies, we illustrate processes in translating case report forms to increase language diversity in study populations while simultaneously highlighting implications for data collection and analyses. The Northwestern University Data Analysis and Coordinating Center manages the translation of participant-facing study documents into languages other than English through a process that has been refined over several years, adjusting for changes in technical capabilities in electronic case report forms. This approach to manage, examine for context, and implement certified case report form translations offers an efficient workflow to streamline data capture in multiple languages.

OBJECTIVES/SPECIFIC AIMS: The accurate and efficient serial measurement of patient centered outcomes is a priority in the clinical care of systemic lupus erythematosus (SLE). Patient-Reported Outcomes Measurement Information Systems (PROMIS®) Global Health Short Form (PROMIS10) is a 10-item universal patient reported outcome measure of global physical and mental health with construct validity in SLE. The longitudinal responsiveness (sensitivity to change) of PROMIS10 in SLE patients is unknown. We aimed to evaluate the responsiveness of PROMIS10 in SLE outpatients using patient and physician-derived anchors. METHODS/STUDY POPULATION: Adults meeting SLE classification criteria were recruited from an SLE Center of Excellence. Subjects completed PROMIS10 at two visits a minimum of one month apart. SLE disease activity was measured with a patient global assessment of change, a physician global assessment and the physician-derived SELENA-SLEDAI. Responsiveness over time of PROMIS10 scores was evaluated using known-groups validity. Effect sizes of changes in PROMIS global physical health and global mental health scores from baseline to follow up were compared across groups of patients who differed in their patient global assessment of change, physician global assessment, and SELENA-SLEDAI using Kruskal-Wallis tests. RESULTS/ANTICIPATED RESULTS: A diverse cohort of 228 SLE patients completed baseline surveys (Table 1), with 190 (83%) completing a follow up survey. Using the patient-based anchor, PROMIS10 demonstrated mild to moderate responsiveness to improvement (effect size 0.29) and worsening (effect sizes −0.27 and −0.54) of health status for both global physical health and global mental health (Table 2). Using the physician global assessment and SELENA-SLEDAI as anchors, there were no statistically significant differences in effect sizes across groups. DISCUSSION/SIGNIFICANCE OF IMPACT: PROMIS10 showed responsiveness over time to patient-reported, but not physician-derived changes in lupus health status. These data suggest that PROMIS10 can be used to efficiently measure and monitor important aspects of the patient experience of lupus not captured by physician-derived metrics. Further studies are needed to evaluate the role of PROMIS in optimizing longitudinal disease management in SLE.

OBJECTIVES/SPECIFIC AIMS: Objective: Identify barriers and facilitators of positive patient-provider interactions for AAN patients. METHODS/STUDY POPULATION: Methods: Using a mixed-methods, longitudinal, patient-interview design, N = 29 (to date) women with a history of AAN have been enrolled. Each patient completed a diagnostic interview and standardized surveys to establish ED diagnosis, severity, and associated psychopathology. Transcribed, semi-structured qualitative interviews are assessed for common themes using content analysis methods. RESULTS/ANTICIPATED RESULTS: Anticipated Results: Patients aged 18 to 74 (M = 36.3, SD = 12.0), with mean BMI = 39.8 (22.7-61.1; SD = 11.3), and mean weight suppression (lbs) during their illness = 119.41 (SD = 69.3). Women reported a mean=12.75 years (0-37 years, SD = 10.5) treatment delay. Qualitative analysis revealed the following barriers in healthcare provider interactions: 1) experiences of provider weight-bias, 2) low specificity in ED screening questions, 3) lack of indicated screening procedures/diagnostic tests (orthostatic screening, EKG, food log, labs), and 4) provider praise of ED behaviors. Facilitators: 1) lower BMI at presentation, 2) provider education in EDs, 3) community-provider collaboration, and 4) patient self- and family- advocacy. DISCUSSION/SIGNIFICANCE OF IMPACT: Discussion: Unfortunately, while early intervention best predicts positive outcomes, higher-weight patients in this study experienced significant treatment delay. Translationally, it is taking too long for AAN patients to receive the right treatment at the right time. However, findings indicate that interventions at the provider level (increasing ED education, building community partnerships, increased adherence to screening protocols) could improve screening, diagnostic, and referral practices—and ultimately long-term outcomes for this unique patient population.

Objectives/Goals: Neuromodulation strategies like transcranial magnetic stimulation (TMS) can target specific neural circuits underlying particular psychiatric symptoms, potentially 1) enhancing understanding of mechanisms of illness and recovery and 2) acting as novel therapeutics. These feasibility studies lay foundation for a study of major depression. Methods/Study Population: Four healthy volunteers completed structural and functional MRI (fMRI). fMRI included a trait-adjective task, a negative self-referential processing task known to activate VMPFC, which is known to be abnormal in major depression. During the task, participants respond on a task pad whether they feel that each of a series of displayed adjectives (positive, negative, or neutral) applies to them. Three participants then participated in a simulated image-guided TMS session using their MRI data to target their VMPFC. Three-dimensional tracking of the participant’s head and the TMS coil was used to position the coil for peak stimulation of the targeted brain region. Results/Anticipated Results: Our team collected quality neural and behavioral data on the fMRI task; participants reported a tolerable experience. Simulated neuronavigated TMS showed feasibility and tolerability of positioning the device to stimulate VMPFC. The fMRI task activated the VMPFC as predicted. The MRI and TMS protocols were replicable and tolerable. These procedures can now be used experimentally by our team with confidence to test our hypothesis that targeting the VMPFC within the brain’s default-mode network may normalize aberrant VMPFC activity seen in major depression, thereby improving excessive negative self-referential processing. Discussion/Significance of Impact: This project lays essential groundwork for my K12 project, “Targeting Negative-Self Referential Processing in Depression with TMS,” a longitudinal neuroimaging and behavioral study using these methods in the study population of people with major depression.

Objectives/Goals: Translational research teams span varied roles, disciplines, and institutions. They rely on information to collaborate, communicate, and coordinate. Information should flow seamlessly for collaborative success, yet we know little about the collective information needs and challenges of such teams, representing a translational science problem. Methods/Study Population: We report on the Information Management Prototype for Clinical and Translational Research (IMPACT-CTR) study which explored how clinical and translational research teams (CTRTs) manage their information while conducting collaborative research. Participants across 11 US-based CTRTs (n=52) participated in brief surveys and interviews about their collaborative processes. We are following the Translational Team Science Hierarchy of Needs (Kelly et al., 2023) framework in our thematic analyses, where we are sequentially examining: (1) the foundation of information infrastructure (tools and resources), (2) teams’ information management practices, and (3) how these practices affect psychological safety of team members, which then impact “translational nirvana” or the research synergy of CTRTs. Results/Anticipated Results: Preliminary analysis revealed that information was crucial to CTRTs’ functionality but often overlooked. Team members moved through the research lifecycle by juggling numerous types of information spread across multiple tools, while balancing their personal information styles with those of the collective. Subsequent analyses will investigate the challenges, workarounds, and lessons CTRT members have learned while managing their information and relying on each other as information resources, and the extent to which these factors impact their scientific and operational work, as well as their team culture. We will thus develop and present a conceptual framework of how CTRTs’ information behaviors can facilitate or impede high-impact collaborative research. Discussion/Significance of Impact: We will present reproducible team science practices that can enhance the process of scientific research through evidence-based information management practices that are both effective and feasible for CTRTs. In doing so, we will identify information-related barriers that hinder the efficiency of the translational research continuum.

Objectives/Goals: To assess how rigor and reproducibility activities across the Clinical and Translational Science Awards (CTSA) consortium are aligned with NCATS Translational Science Principles (TSPs) and the NIH’s new plan to promote gold standard science. Methods/Study Population: We conducted a retrospective, descriptive review of all CTSA hub Research Performance Progress Reports (RPPRs) submitted for the most recent reporting year, focusing on the Accomplishments section. Reports were systematically searched using predefined rigor and reproducibility-related keywords. Relevant content was abstracted using a structured framework to categorize activities across domains, including education and training, institutional support, and data management and sharing. Results were summarized quantitatively by award mechanism. Results/Anticipated Results: Sixty-two of 66 CTSA institutions reported activities related to scientific rigor and reproducibility in the RPPR Accomplishments section. Among these hubs, rigor and reproducibility activities were most frequently reported under K awards (48 hubs), followed by UL2 or UM1 awards (43 hubs) and T awards (38 hubs). These findings indicate broad engagement across the CTSA consortium, with variation in how rigor and reproducibility activities are reported across award mechanisms. Discussion/Significance of Impact: Most CTSA hubs document multiple rigor and reproducibility activities as their accomplishments, reflecting alignment with NCATS TSPs. Characterizing these efforts across award mechanisms can inform strategies to strengthen translational science research that meets the NIH’s gold standard science.

OBJECTIVES/GOALS: The primary purpose of the QA/QC Project Manager (PM), appointed under the NCATS UL1 administrative supplement award, is to facilitate quality and timely NCATS prior approval submissions preventing study start delays. Other goals include supporting these projects’ IRB applications and monitoring to ensure data quality and compliance. METHODS/STUDY POPULATION: At the Indiana CTSI, the QA/QC PM is assigned to the Regulatory Knowledge and Support program (RKS) and functions as a unique regulatory service provider. Through monitoring, auditing, and personalized consultations, the IN CTSI QA/QC PM provides study teams with regulatory, GCP, and other compliant study conduct insights while managing NCATS prior approval and RPPR submission quality and timeliness. In contrast to many CTSAs, this role is uniquely situated within RKS and provides QA/QC support through a regulatory lens. The Indiana CTSI QA/QC PM serves on the CTSA QA/QC Lead Team collaborating with NCATS and other CTSA QA/QC personnel. The Lead Team engages with NCATS to host monthly/quarterly meetings and participate in a discussion forum of NCATS and other CTSA QA/QC personnel. RESULTS/ANTICIPATED RESULTS: Not all CTSAs employ the QA/QC PM as regulatory support and the role and skill sets at each CTSA vary, yet the collaborative nature of these individuals across the CTSAs facilitates sharing of resources and knowledge. While prior approval and RPPR submissions vary widely, the QA/QC PMs can rely on their counterparts for guidance complying with the same regulations and policies within unique research settings and institutional nuances. The IN CTSI QA/QC PM, in collaboration with the QA/QC Lead Team, provided quality assurance revisions to the NCATS prior approval instructions which were adopted and published by NCATS January 2022 for implementation at all CTSAs. Ongoing, quality control efforts are accomplished through education, monitoring, and regulatory consultations. DISCUSSION/SIGNIFICANCE: As the research environment evolves, the QA/QC PM responsibilities shift in response to needs within RKS and NCATS. The versatility of the position enables QA/QC to occur at all stages of a study. QA/QC strategies aim to facilitate communication, quality NCATS prior approval and RPPR submissions, and compliance with proposed study conduct.

OBJECTIVES/GOALS: To identify challenges faced by academic researchers in accessing online regulatory information and/or tools to advance their research work to develop a free, publicly accessible, interactive web portal that provides regulatory support. METHODS/STUDY POPULATION: The Regulatory Knowledge and Support core of the Southern California Clinical and Translational Science Institute interviewed five local research professionals. These interviews guided the development of a Qualtrics survey, consisting of multiple responses and open-ended questions, submitted to our local institutional review board (IRB). After receiving IRB approval, the survey was disseminated via email, newsletters, flyers, and presentations targeting researchers at academic institutions and members of clinical and translational science hubs. Survey data will be used to identify the challenges academic researchers face in finding regulatory resources and to compile the types of regulatory information or tools they would find helpful for their research. RESULTS/ANTICIPATED RESULTS: According to the interviews, researchers with extensive involvement in clinical trials found regulatory resources easily accessible compared to those with less experience. Additionally, they all stated having a colleague or regulatory specialist whom they can consult about regulatory requirements. Insights from these initial interviews confirmed the need to obtain a comprehensive view across research professionals. Anticipated results will show the challenges in accessibility, source, and type of regulatory resources researchers typically encounter. It is also anticipated that researchers will share what kinds of resources they would find most useful for their work. Ultimately, the information and tools identified as essential by survey takers will be collected and incorporated into the web portal. DISCUSSION/SIGNIFICANCE: Academic researchers find navigating through regulatory hurdles persistently challenging when translating their work from bench to clinic, especially since academia is typically resource-constrained. Findings from this study will allow the creation of a web portal for researchers that is broadly accessible and meets their regulatory needs.

OBJECTIVES/GOALS: Although their 5-year survival >90%, young patients with HL face tradeoffs between near-term disease control and risk of treatment-related adverse effects decades later, so we seek to understand what patients and clinicians value in HL treatment decisions. METHODS/STUDY POPULATION: Leveraging our access to large cohorts of physicians, HL patients/survivors, and caregivers, we will use adaptive choice-based conjoint analysis (ACBC) to elicit treatment preferences when offered scenarios that incorporate tradeoffs, e.g., would a patient rather live 20 years with 10% risk of second malignancy or live 40 years with 30% of second malignancy. To reduce survey fatigue, prior choice responses limit subsequent scenarios. Through ACBC, we will identify variations in preferences and the importance of disease outcomes, treatment characteristics, and late effects for HL by respondent type. RESULTS/ANTICIPATED RESULTS: The goal is a final sample of 200 physicians and 200 patients/caregivers. We will collect demographics from physicians (age, type of physician, years practicing, type of practice, gender, and geography) and patients/caregivers (age at diagnosis, time since treatment, race, gender, smoker, education). We will ask questions about values of disease outcomes, late effects (second cancers, cardiac disease, chronic fatigue and neuropathy), and treatment characteristics (uncertainty of late effects, salvageability). Results will include utilities about participants views on disease-control and late effects. We anticipate participants to value disease control over late effects. DISCUSSION/SIGNIFICANCE OF IMPACT: Our study will elicit how physicians and patients/caregivers value treatment tradeoffs for HL. In an era of multiple treatment choices with varying short- and long-term benefits and harms, identifying values and preferences become critical for patient-centered treatment decisions.

Objectives/Goals: The use of evidence-informed project management (PM) frameworks such as Agile has the potential to increase the productivity, rigor, and reproducibility of collaborative team science. This poster explores our work with Clinical and Translational Research teams to evaluate and disseminate lightweight, flexible PM tools. Methods/Study Population: Training research teams in the development of systematic approaches to PM has the potential to increase teams’ ability to conduct high-impact Clinical and Translational Research. Here, we report on two research activities at the Michigan Institute for Clinical and Translational Research (MICHR). First, we share data from the NIH-funded IMPACT-CTR study that demonstrate the impact PM systems have on how teams collaborate. Second, we share results of ongoing User Experience (UX) testing of Notion-based PM templates specifically designed to facilitate Team Science. We engaged postdoctoral fellows, early-career researchers, and project managers to assess the acceptability, usability, and feasibility of implementing these templates. Results/Anticipated Results: Results from the IMPACT-CTR study demonstrate the importance of lightweight, accessible PM systems that facilitate robust teamwork. Teams with defined, well-documented PM approaches reported lower levels of conflict, as well as higher levels of research productivity and team satisfaction. Further, PM systems depend on and influence teams’ information and data management approaches, also key contributors to a team’s ability to achieve their scientific objectives and conduct rigorous, reproducible research. We anticipate that results from UX testing of PM templates will demonstrate high levels of interest in implementing these tools to support collaborative research, providing an accessible entry point to proven PM strategies standard adapted from other fields. Discussion/Significance of Impact: Providing context-appropriate, flexible, and adaptable PM tools as well as training in PM best practices to science teams has the potential to streamline team communication and collaboration, improve efficient use of funding, and enhance research productivity. Studying such implementations will yield additional insights for Team Science.

Objectives/Goals: Increased follicle-stimulating hormone (FSH) is linked to declines in ovarian and metabolic function in older women. Obesity is both a manifestation and a driver of aging pathologies. In animal models, FSH and insulin resistance (IR) were reduced after 6 mos. of a nutritional therapeutic (GLYLO). Our goal was to translate preclinical evidence to humans. Methods/Study Population: An integrated, precision medicine approach identified a unique phenotype of aging-related debility relative to older females. A non-comparer pilot study was conducted to translate GLYLO preclinical findings to postmenopausal women with obesity (n = 85; >55 years; body mass index [BMI]  = 35.0±4.35; range: 30.3–42.8). Participants meeting the inclusion and exclusion criteria (n = 13) were enrolled and received two capsules of GLYLO (vitamins and natural products) daily for 6 mos. Assessments for FSH, estradiol (E2), IR (homeostatic model [HOMA-IR]), total cholesterol (TC), low- (LDL), high-density lipoproteins (HDL), safety biomarkers (e.g., red cell distribution width [RDW%], mean corpuscular volume [MCV]), and depression (Center for Epidemiologic Studies Depression Scale) were conducted prior to and after 6 mos. Results/Anticipated Results: Mixed-effect models with intent-to-treat analysis were applied to compare outcomes prior to (n = 13) and following (n = 7) the intervention. Significant reductions in FSH were observed (-13.1 [2.47] ∆/SD; p = 0.002)) following the 6-month intervention. Interestingly, BMI, E2 (p = 0.412), HOMA-IR (p = 0.885), TC (p = 0.363), and LDL (p = 0.145) were unchanged, while HDL decreased significantly (-9.7 [3.82] ∆/SD; p = 0.044). Other biomarkers, RDW% (-0.2 [0.05] ∆/SD; p = 0.009) and MCV (-2.3 [0.33] ∆/SD; p = 0004), were significantly reduced. All other safety parameters were not altered. Six participants reported mild to moderate adverse events (acid indigestion) and were lost to follow-up. Depression scores significantly increased (+4.0 [0.75] ∆/SD; p = 0.002)). Results were similar with and without intent to treat analysis. Discussion/Significance of Impact: Decreased FSH, but not IR, was observed following six months of GLYLO in postmenopausal women with obesity. Significant alterations in HDL, depression, RDW%, and MCV warrant further investigation. Findings are limited by the small sample size and loss to follow-up. Randomized, controlled trials are needed to confirm these results.

OBJECTIVES/SPECIFIC AIMS: According to Diffusion of Innovations Theory, an important predictor of successful implementation of a new intervention within an organization is perceived need for change (i.e. tension for change [TFC]). No research has examined factors influencing TFC in relation to human papillomavirus (HPV) vaccination. Providers who assume their clinic already performs well in HPV vaccination coverage may perceive a lower need for assistance for improvement. We assessed the association between perceived HPV vaccine completion compared to peer clinics and perceived support needed to increase HPV vaccination coverage. METHODS/STUDY POPULATION: All providers (physicians/nurse practitioners/physician assistants) and staff (clinical/non-clinical) from 21 pediatric clinics participating in an HPV vaccine quality improvement (QI) intervention study in Tennessee were invited to complete a baseline survey. Perceived comparative performance (i.e. perceived HPV vaccine completion compared to peer clinics) and TFC (i.e. perceived support needed to increase HPV vaccination coverage) were measured on continuous scales of 0-100. We used logistic regression to estimate odds of perceiving higher TFC (upper tertile, score of 51-100) for every unit increase in perceived comparative performance. Analyses controlled for age of respondent, perceived strength of evidence for HPV vaccine guidelines, and clinic factors, including culture/climate and available resources. RESULTS/ANTICIPATED RESULTS: Of 325 respondents, most were staff (61%), female (87%), and non-Hispanic White (83%). Respondents who perceived higher HPV vaccination coverage compared to peer clinics perceived lower clinic-level TFC (adjusted OR [aOR] = 0.98; 95% CI, 0.97-0.99). When stratifying by job role, this negative association was observed among providers (aOR = 0.95; 95% CI, 0.92-0.98), but not among staff (aOR = 1.00; 95% CI, 0.98-1.03). DISCUSSION/SIGNIFICANCE OF IMPACT: Providers who perceived higher HPV vaccination coverage compared to peer clinics perceived lower need for support to improve vaccination outcomes. Our results suggest that QI efforts targeting pediatric clinics may find it useful to assess providers’ perceptions of their clinic’s performance, which could affect motivation to engage in QI efforts and successfully improve outcomes.

OBJECTIVES/GOALS: Examine the use of Patient-Reported Outcomes (PRO) in Huntington’s Disease (HD) clinical trials (CT) and compare across time and sponsor types. METHODS/STUDY POPULATION: Conduct literature review on 1. background of HD, 2. what symptoms and outcome measures are most important to patients, including the Patient-Focused Drug Development (PFDD) meeting for HD–led by the U.S. Food and Drug Administration (FDA), 3. what outcome measure tools currently exist and what they measure. Utilizing Clinicaltrials.gov, trials for HD were examined to assess the number of trials conducted, what COAs were used, and funding types. Trials were filtered by study type (keep Interventional) and status (filter out suspended, terminated, unknown, and withdrawn). The frequency of COAs will then be mapped based on the symptoms from the PFDD meeting. RESULTS/ANTICIPATED RESULTS: From the PFDD meeting for HD, symptoms that were important to patients include cognitive impairment, depression and anxiety, and motor symptoms. From the 139 interventional studies that were active, complete, recruiting, or not recruiting, 79 studies were conducted by Industry, 3 by NIH, 93 by Other (Academia/Community Organizations), and 1 by a U.S. Federal Agency (other than NIH). One of the most commonly used COA is the Unified Huntington’s Disease Rating Scale (UHDRS), which includes a motor, cognitive, and behavior assessment, and an assessment on functional capacity and independence. Of the 27 out of 139 trials analyzed to date, there were a total of 37 COAs. DISCUSSION/SIGNIFICANCE: The widespread use of UHDRS can be attributed to its standardization in 1999. It captures the symptoms of HD that are most important to patients. Because UHDRS is not sensitive to any one symptom, other COAs have been developed which focus on unique aspects of HD and allow for its earlier detection.
