Abstract OBJECT Under-enrollment in clinical trials significantly limits valid analyses of clinical interventions and generalizability of findings. Often it results in premature study termination, with estimates of 22% to 50% of clinical trials terminated due to poor accrual. Currently, there are limited reports addressing the influence of race/ethnicity and socioeconomic status on clinical trial enrollment in patients with adult glioma. The goal of this study was to determine if these factors impact clinical trial participation for glioma patients. METHODS 852 adult patients were identified from the UCSF Tumor Board Registry and analyzed to determine the rate of therapeutic clinical trial consideration, tumor board recommendation, and study enrollment based on clinical reports in their electronic medical records. RESULTS At initial diagnosis, 30.7% and 18.0% of glioma patients were recommended and enrolled in a therapeutic clinical trial, respectively. At recurrence, 38.7% and 25.3% of patients were recommended and enrolled in a clinical trial, respectively. Nineteen percent of the study population belonged to a NIH-designated underrepresented minority group; Asian/Pacific-Islander comprising 10.3% overall. On univariate analysis, only in-state location, distance to the hospital, and WHO grade were associated with consideration, recommendation, and enrollment at initial diagnosis and recurrence. Minority status, insurance type, median household income, and percent below poverty were not associated with clinical trial recommendation or enrollment. CONCLUSION Race and socioeconomic status did not impact clinical trial consideration, tumor board recommendation, or study enrollment. Our results do not support the premise that provider decisions are impacted by biases based on minority or socioeconomic status.

128 Background: Sparse data exists on the diversity clinical trial enrollment in community settings. This information is important to ensure equity of care and generalizability of results. Methods: We conducted a retrospective cohort study of members of an integrated healthcare system diagnosed with invasive malignancies (excluding non-melanoma skin cancers) between 2013-2017 to examine demographics of the oncology population compared to those who enrolled in a clinical trial. Logistic regression was used to assess correlates of clinical trial participation, comparing general and screened samples to enrolled sample. Odds ratios were adjusted for gender, geocoded median household income, cancer type, and stage. Results: Of the 84,977 patients with a cancer diagnosis, N = 2606 were screened for clinical trial participation and consented, and of those N = 1372 enrolled. The percent of Latinx (25.8% vs 24.0%; OR 0.9? CI 0.72-1.05) and African American/Black (10.9% vs 11.1%; OR 0.92 CI 0.75-1.11) clinical trial participation mirrored that of the general oncology population, respectively using Non-Hispanic Whites as reference. Asian/Pacific Islander had equal odds of clinical trial enrollment (OR 1.08 CI 0.92-1.27). The enrolled population was younger than the general oncology population. Conclusions: This study suggests that in an integrated healthcare system with equal access to care, the clinical trials population is well representative of its general oncology population.[Table: see text]

Introduction: The COVID-19 Pandemic has mandated limiting routine visit frequency for patients with chronic cardiovascular (CV) diseases. In patients with heart failure (HF) followed longitudinally, the period of clinical trial participation provides an opportunity to evaluate the influence of high-frequency per-protocol in-person visits compared to less frequent routine visits during longitudinal clinical care. Hypothesis: Patients enrolled in clinical trials will have a lower CV and HF event rates during periods of trial enrollment than during non-trial periods. Methods: We examined clinical characteristics, CV and HF hospitalization rates, and outcomes in patients with HF receiving longitudinal HF care at a single center. We evaluated hospitalization rates during the 1-year preceding trial enrollment and hospitalization and death rates during enrollment in clinical trials and for up to 1 year following trial completion. Results: Among the 121 patients enrolled in HF clinical trials, 72% were HFrEF (age 62±11, 19% females, BMI 30.4±6.0, LVEF 25±7, NYHA 2.7±0.6, NT-proBNP 2336±2671) and 28% were HFpEF (age 69±9, BMI 32.1±5.5, 29% females, LVEF 60±10, NYHA 2.4±0.5, NT-proBNP 957±997). Average clinical trial exposure was 8±6.6 months. Per-protocol visit frequency was 16±7 per year during clinical trial enrollment. In the one-year pre-trial period, compared to the within-trial period, CV hospitalizations were 0.88/patient-year vs. 0.32/patient-year (p<0.001) and HF hospitalizations were 0.63/patient-year and 0.24/patient-year (p<0.001), with a mortality rate of 0.04/patient-year during trial participation. In the period of up-to 1 year following the end of trial enrollment CV and HF hospitalizations were intermediate at 0.51/patient-year and 0.27/patient-year with an annualized incremental mortality rate of 0.03/patient-year. Conclusion: In HF patients followed longitudinally at a single center, periods of clinical trial enrollment were associated with high visit frequency and lower CV and HF hospitalization rates. These findings highlight the potential benefits of trial enrollment and high-frequency visits for HF patients at a time when routine visit frequency is being carefully considered during the COVID-19 Pandemic.

e18574 Background: Minorities continue to be underrepresented in clinical trials despite the National Institute of Health’s Revitalization Act, passed in 1993, mandating the representation of women and underrepresented minority groups in clinical trials. Studies have shown that although Blacks represent 15% and Hispanics 13% of the cancer population, their clinical trial enrollment rates in are disproportionately low at 4-6% and 3-6% respectively. We conducted a systematic review exploring interventions aimed at improving clinical trial enrollment for racial and ethnic minorities. Methods: A systematic search of PubMed, Cochrane CENTRAL, and Ovid PsycINFO was conducted for English-language studies of humans since 1993. Inclusion criteria included peer-reviewed, U.S.-based studies with interventions aimed to recruit underrepresented minority adult cancer patients into cancer clinical trials. We defined underrepresented minority groups as Black, Hispanic/Latino, Asian, American Indian/Alaska Native and Native Hawaiian/other Pacific Islander. Results: A total of 2471 titles and abstracts were identified and 2324 were excluded based on the eligibility criteria. A full text review was conducted of the remaining 147 articles, of which only 9 met criteria for our review. The interventions included patient navigation/coaching (n = 4), a clinical trial educational video (n = 2), institutional research infrastructure changes (n = 1), a relationship building and social marketing recruitment model (n = 1) and cultural competency training for providers (n = 1). Studies were conducted in a variety of practice settings including national cancer institutes and community practices. The quality of evidence was limited by the heterogeneity of study methods, patient representation and bias. Several studies had a homogeneous population of Black patients. Most studies (n = 7) were single arm trials that compared results to either historical controls or those cited in the existing literature; two studies were randomized controlled trials. A statistically significant improvement in accrual was shown in three of the patient navigation interventions, one of the clinical trial educational videos, the institutional research infrastructure change and the relationship building and social marketing recruitment model. The common threads to many of these successful interventions were support through the cancer care continuum, cultural congruency of research staff and culturally catered clinical trial educational materials. Conclusions: This systematic review illustrates several mechanisms by which to increase cancer clinical trial recruitment for cancer patients of underrepresented minority backgrounds in a variety of clinical settings. Randomized controlled trials with representation of multiple races/ethnicities are needed to further explore the benefits of these interventions.

53 Background: Increasing black patients’ participation in cancer clinical trials is particularly important because of the population’s lower survival rate. Accrual to clinical trials remains low among the general population (1 to 3%), with recruitment of blacks the lowest of all groups at 0.5 to 1.5%. Clinical trials are key to developing new methods to prevent, detect, and treat cancer. INSPIRE-BrC aims to increase trial participation rates among black patients with breast cancer and examine the relationship between the intervention and attitudes/beliefs on the decision to participate. Methods: A sample size of 123 black patients with breast cancer at five MedStar sites will view a 15 minute, culturally tailored video about clinical trials, which targets six cultural and attitudinal barriers to participation. A pre-test/post-test method is used to determine the impact of the video on three variables — likely participation in therapeutic clinical trials; attitudes toward therapeutic clinical trials (assessed based on the 6 barriers); and actual trial enrollment. Expected Findings: We hypothesize that the intervention will increase clinical trial enrollment compared to our 2012 clinical trial enrollment baseline rate of 6% (22/384) for black patients with breast cancer in five MedStar hospitals. The primary outcome measure is the proportion of black patients with breast cancer who agree to participate in a therapeutic clinical trial among those who sign consent to INSPIRE-BrC. Study findings have the potential to increase patient recruitment as a promising tool for rapid dissemination of a theory-driven, evidence-based model to enhance clinical trial accrual among black patients with cancer.

198 Background: We reported in 2011 at the Society of Surgical Oncology a 19 year retrospective at a single academic institution which identified practice differences between surgical oncologists and general surgeons which were associated with a significant survival advantage. Clinical trial participation was much higher amongst patients treated by a surgical oncologist. Methods: This is an IRB approved, retrospective review of all breast cancer patients receiving primary treatment at a single institution from 1/1/2001 to 12/31/2008. Details of pathology, surgical therapy, chemotherapy, hormonal therapy and radiation therapy were compared between patients participating in clinical trials and those not participating. The specific trials were segregated as to type (tissue banking, therapeutic, prevention, etc.) to understand differential effects if any between type of trial participation. Results: During the time period, there were 1220 patients who received primary breast cancer treatment at this institution. The mean age was 55.6 and mean follow-up >40 months. Stage distribution was stage 0 - 16.8%, Stage 1 - 26.6%, Stage 2 - 33.1%, Stage 3 - 15.9%, and Stage 4 - 6.1%. Patients participating in any clinical trial numbered 468 and 752 participated in no clinical trials. Overall survival (clinical trial 98.8% vs. not in clinical trial 75.7%; p<0.0001). Overall the use of breast conservation was more likely in clinical trial participants (54.3% vs. 44.4%; p<0.0001). The completion of chemotherapy was more likely in clinical trial participants (52.4% vs. 49.5%; p=0.02).The successful completion of systemic therapies (chemo and hormonal) was more likely also (71.4% vs. 64.0%; p=0.009). The type of trial (tissue banking vs. therapeutic) had no effect on improved outcomes. Overall the best predictor of better outcomes was to be treated by a high volume clinical trial enrolling physician. Conclusions: High volume clinical trial enrollment is associated with the best overall treatment outcomes in breast cancer whether trials are directly related to therapeutic changes or not. Each individual in the breast center treating team can have dramatic effect on outcomes by improving their clinical trial enrollment and participation.

167 Background: Patient enrollment to clinical trials is lower than desired. Even large organizations with extensive research support services have many barriers to recruitment and poor rates of enrollment. Barriers to clinical trial participation can be physician related, system related, or patient related. Physician related issues are the largest barrier to patient accrual. Physicians are often not aware that a trial may be available for a patient. While all initial patients are manually screened in our system, screening for subsequent lines of therapy are not. Provider awareness and appropriate patient identification are areas of potential improvement in a large, multisite, hospital affiliated, community oncology setting. Methods: Our oncology group recently implemented Via Oncology (Via), an EHR-integrated clinical pathway decision support tool. Information about the patient, their disease, and goals of care generate a recommended treatment algorithm. The pathways are expected to speed the integration of new treatments into practice and improve accrual to clinical trials. Use of Via is required for all new therapy changes. Within the decision algorithm, an appropriate available clinical trial is suggested as the first option when available. Clinical trial enrollment statistics are being tracked to determine if this method of potential patient identification results in increased enrollments. Results: After 11 months of Via implementation and 103,515 visits, the visit capture rate was 82.7% suggesting that providers adapted to the pathways quickly. With 3,844 decisions made, 83.9% of all treatment decisions were on pathway. Clinical trial enrollment was 122 patients in the 459 days prior to Via implementation, and 102 patients in the 271 days afterwards. This increase in accrual rate was significant (p = 0.00174.) Conclusions: Early results suggest that Via implementation has resulted in a significant increase in clinical trial accrual. The system will eventually be able to track how often a trial is offered and how often it is accepted. We are hopeful that with complete visit capture of all patients, there will be continued improvement in our rate of clinical trial enrollment.

Abstract Survival among adolescents and young adults (AYAs) ages 15 to 39 with cancer has not improved to the same extent as that of pediatric and older adult cancer patients, which is thought to relate, in part, to the lower participation of AYAs in clinical trials. Because significant efforts have been made to improve clinical trial enrollment for AYAs, we (1) present contemporary clinical trial enrollment rates by cancer type, sociodemographic characteristics, and treatment setting and (2) discuss provider-, patient-, and system-level barriers to clinical trial participation. Contemporary studies examining clinical trial enrollment among AYAs have continued to find low overall participation relative to pediatric populations, with most studies observing no significant improvements in enrollment over time. In addition to age and cancer type, enrollment varies by treatment setting, health insurance, and race/ethnicity. Access to available clinical trials may be increased by appropriate referral of AYAs to pediatric and adult specialty cancer centers with studies relevant to the AYA population because most AYAs are treated in the community setting. Even with similar access to trials, however, AYAs may be less likely to participate, and therefore, future efforts should focus on better understanding and addressing barriers to enrollment as well as improving education and outreach regarding clinical trials.

Clinical trials are imperative for testing novel cancer therapies, advancing the science of cancer care, and determining the best treatment strategies to enhance outcomes for patients with cancer. However, barriers to clinical trial enrollment contribute to low participation in cancer clinical trials. Many factors play a role in the persistently low rates of trial participation, including financial barriers, logistical concerns, and the lack of resources for patients and clinicians to support clinical trial enrollment and retention. Furthermore, restrictive eligibility criteria often result in the exclusion of certain patient populations, which thus adds to the widening disparities seen between patients who enroll in trials and those treated in routine practice. Moreover, additional factors, such as difficulty by patients and clinicians in coping with the uncertainty inherent to clinical trial participation, contribute to low trial enrollment and represent key components of the decision-making process. Specifically, patients and clinicians may struggle to assess the risk-benefit ratio and may incorrectly estimate the probability and severity of challenges associated with clinical trial participation, thus complicating the informed consent process. Importantly, research has increasingly focused on overcoming barriers to clinical trial enrollment. A promising solution involves the use of patient navigators to help enhance clinical trial recruitment, enrollment, and retention. Although clinical trials are essential for improving and prolonging the lives of patients with cancer, barriers exist that can impede trial enrollment; yet, efforts to recognize and address these barriers and enhance trial enrollment are being investigated.

Abstract Introduction Equitable and diverse clinical trials participation is essential for practice-changing results to be applicable to all patients. However, patients who identify as minorities, who live in rural areas, and who have low income are typically underrepresented in clinical trials. Increasing clinical trial participation in general and among underrepresented patients in particular is a goal of The Leukemia & Lymphoma Society's (LLS) Clinical Trial Support Center (CTSC), a clinical trial nurse navigation service for patients with blood cancers and their oncologists. The Veterans Health Administration (VA) is a national network of health care facilities. Approximately 3% of cancers in the United States are diagnosed in the VA. The prevalence of certain blood cancers is higher in the VA, in part due to military exposures. Veterans who receive care in the VA are more likely to have lower income, live in rural areas, and have comorbidities than patients who receive care in the private sector. Clinical trial participation among Veterans may be hampered by VA-specific factors (e.g. relatively fewer clinical trial options in the VA, lack of awareness that Veterans may be referred to participate in clinical trials outside of the VA) and patient-specific factors (e.g. income, rurality, comorbidities, and minority status). This study aimed to characterize and overcome barriers to Veteran enrollment in blood cancer clinical trials. Methods The LLS CTSC performs clinical trial searches using a database with information from clinicaltrials.gov and other proprietary data. To assess the impact of geography and rurality on the availability of clinical trials, we performed simulated searches for clinical trials in proximity of 13 VA facilities (6 rural, 7 urban), six blood cancers (AML, CLL, DLBCL, FL, MDS, MM), and two disease statuses (new diagnosis, relapsed/refractory). To further evaluate barriers to CTSC referral and clinical trial enrollment among Veterans who receive care in the VA, we collected data about referral patterns of VA hematologist-oncologists and Veterans' treatment choices at four VA facilities between September 2020 through May 2021. Results When evaluating both 100- and 200-mile radii from the VA facilities in simulated searches, there were significantly more clinical trials available for Veterans who receive care in urban compared to rural areas and on the East or West Coast compared to the Midwest, in aggregate (all cancers) and by disease type or status (p unadj &lt; 0.0001). Forty-eight Veterans with blood cancers at the Durham NC, Salem VA, Sioux Falls SD, and Clarksburg WV VA facilities had consideration of clinical trials as a treatment option by oncology providers over a nine-month period. All Veterans were male, with 33 White/15 African-American, 47 non-Hispanic/1 Hispanic, age 41-93 years (median 71), living 0.2-186 miles from their VA facility (median 33.1), with diverse diseases and stages represented. Of the 48 patients, 14 patients were not asked if they wanted clinical trials information; reasons were need for immediate therapy, co-morbidities, or patient circumstances. Of 34 patients who were asked if they wanted clinical trials information, 14 did not agree to a referral to the CTSC; reasons were preference for immediate therapy, wanting care in the VA, wanting standard therapy, and lack of transportation. Of 20 referred Veterans, two enrolled in clinical trials outside the VA (for CLL and PMF), with investigational therapy provided by the study sponsors. Conclusions Using data from simulated and actual patient referrals to the LLS CTSC, we identified patient, provider, and location specific barriers for Veteran referral and enrollment in blood cancer clinical trials. When offered information about clinical trials, the majority of patients agreed to an LLS CTSC referral, suggesting that patients are generally willing to receive education and information about trial participation if given the opportunity. The LLS CTSC nurse navigators can overcome barriers to enrollment by providing education and identifying potential clinical trials within a desired geographic area. In addition to resources provided by the LLS CTSC, opening additional clinical trials in rural areas and within the VA system could help increase Veteran participation in clinical trials for blood cancers.

149 Background: Cancer clinical trial enrollment is low at approximately 3% in the U.S., and there is an urgent need for improvement. Informing patients clinical trial information early at their initial appointment after the diagnosis of cancer may improve clinical trial enrollment. To this goal, we have developed a system-based multidisciplinary breast cancer clinic (MDBCC) that evaluates all newly diagnosed breast cancer cases and discuss with all patients eligible clinical trials at their initial appointment. Methods: Our MDBCC team consists of a medical and radiation oncologist, breast surgeon, mammographer, pathologist, geneticist, and breast cancer coordinators, who review all newly diagnosed cases in the tumor board (multidisciplinary breast cancer tumor board) prior to patient’s MDBCC appointment. During the MDBCC visit, each individual patient meets separately with a medical oncologist, a radiation oncologist, and a surgeon to discuss their treatment options. Eligible clinical trials are discussed and presented to patients with informed consent. Clinical trial nurses are dedicated for patients to call and meet for further discussion on the eligible trials after the MDBCC visit. Results: The average annual clinical trial enrollment for breast cancer was 9 cases (approximately 3%) between 2000 and 2006 prior to initiating the MDBCC, improved to 53 (approximately 17%) between 2007 and 2011 after the MDBCC was formed. The enrollment into the NSABP and SWOG trials accounts for the large portion of the accrual. Conclusions: Early engagement of patients with clinical trial information in a system-based MDBCC for all newly diagnosed breast cancer patients dramatically improves clinical trial enrollment.
