Shared barriers and facilitators to enrollment of adolescents and young adults on cancer clinical trials

Targeted Enrollment in Pediatric Oncology Trials: A Vision for Just-in-Time Matching

@PedsDataCommons shares vision for automated clinical trials matching in pediatric oncology.

Characteristics of Health Care Settings Where Adolescents and Young Adults Receive Care for ALL

PURPOSE

Individuals diagnosed with cancer between 15 and 39 years (adolescent and young adult [AYA]) face unique vulnerability. Detail is lacking about care delivery for these patients, especially those with ALL. We address these knowledge gaps by describing AYA ALL care delivery details at National Cancer Institute Community Oncology Research Program (NCORP) (sub)affiliates by model of care.

METHODS

Participating institutions treated at least one AYA with ALL from 2012 to 2016. Study-specific criteria were used to determine the number of unique clinical facilities (CFs) per NCORP and their model of care (adult/internal medicine [IM], pediatric, mixed [both]). Surveys completed by NCORPs for each CF by model of care captured size, resources, services, and communication.

RESULTS

Among 84 participating CFs (adult/IM, n=47; pediatric, n=15; mixed, n=24), 34% treated 5-10 AYAs with ALL annually; adult/IM CFs more often treated <5 (adult/IM, 60%; pediatric, 40%; mixed, 29%). Referral decisions were commonly driven by an age/diagnosis combination (58%), with frequent ALL-specific age minimums (87%) or maximums (80%). Medical, navigational, and social work services were similar across models while psychology was available at more pediatric CFs (pediatric, 80%; adult/IM, 40%; mixed, 46%-54%). More pediatric or mixed CFs reported oncologists interacting with pediatric/adult counterparts via tumor boards (pediatric, 93%; adult/IM, 26%; mixed, 96%) or initiating contact (pediatric, 100%; adult/IM, 77%; mixed 96%); more pediatric CFs reported an affiliated counterpart (pediatric, 53%; adult, 19%). Most CFs reported no AYA-specific resources (79%) or meetings (83%-98%).

CONCLUSION

System-level aspects of AYA ALL care delivery have not been examined previously. At NCORPs, these characteristics differ by models of care. Additional work is ongoing to investigate the impact of these facility-level factors on guideline-concordant care in this population. Together, these findings can inform a system-level intervention for diverse practice settings.

Delivered relative dose intensity in adolescent and young adult germ cell tumours in England: Assessment of data quality and consistency from clinical trials compared to national cancer registration data

Adolescent and young adults (AYA) with germ cell tumours (GCT) have poorer survival rates than children and many older adults with the same cancers. There are several likely contributing factors to this, including the treatment received. The prognostic benefit of intended dose intensity is well documented in GCT from trials comparing regimens. However, evidence specific to AYA is limited by poor recruitment of AYA to trials and dose delivery outside trials not being well examined. We examined the utility of cancer registration data and a clinical trials dataset to investigate the delivery of relative dose intensity (RDI) in routine National Health Service practice in England, compared to within international clinical trials. Linked data from the Cancer Outcomes and Services Dataset (COSD) and the Systemic Anti-Cancer Therapy (SACT) dataset, and data from four international clinical trials were analysed. Survival over time was described using Kaplan-Meier estimation; overall, by age category, International Germ-Cell Cancer Collaborative Group (IGCCCG) classification, stage, tumour subtype, primary site, ethnicity and deprivation. Cox regression models were used to determine the fully adjusted effect of RDI on mortality risk. The quality of both datasets was critically evaluated and clinically enhanced. RDI was found to be well maintained in all datasets with higher RDIs associated with improved survival outcomes. Real-world data demonstrated several strengths, including population coverage and inclusion of sociodemographic variables and comorbidity. It is limited in GCT however, by the poor completion of data items enabling risk classification of patients and a higher proportion of missing data.

Acute lymphoblastic leukemia in young adults: which treatment?

Despite improvements in survival among pediatric patients with acute lymphoblastic leukemia (ALL), survival outcomes for adolescents and young adults (AYAs) with ALL have lagged. The reasons for the inferior outcomes among AYAs are multifactorial, each presenting unique challenges and requiring novel solutions. First, adverse disease biology is more common among AYAs with ALL. Ongoing trials are investigating novel approaches to treatment, such as incorporating JAK inhibitors for Philadelphia chromosome-like ALL, menin inhibitors for KMT2A-rearranged ALL, and BCL2/BCLXL inhibition for T-cell ALL. Poorer adherence to therapy also impedes improvements in survival outcomes for AYAs with ALL, but early data suggest that technology, both for monitoring and interventions, may be useful in increasing adherence among this population. Finally, better access to clinical trials and collaboration between pediatric and adult centers is critical in advancing the care of AYAs with ALL. Significant improvements have been made over the past decade, but recognizing, understanding, and addressing each of these unique challenges provides hope that the outcomes for AYAs will continue to improve even further.

Leveraging health care technology to improve health outcomes and reduce outcome disparities in AYA leukemia

Significant improvements have occurred for adolescent and young adult (AYA) B-cell acute lymphoblastic leukemia (B-ALL) patients following the widespread adoption of "pediatric-inspired" treatment regimens for AYA patients cared for in adult oncology settings. However, for AYA patients, aged 15 to 39, an outcomes gap remains in B-ALL, necessitating the incorporation of novel therapies into up-front treatment regimens. As a result, clinical trial enrollment remains the current standard of care for AYA B-ALL across disease subtypes when available and accessible. Currently, several up-front trials are looking to incorporate the use of inotuzumab, blinatumomab, and chimeric antigen receptor T-cell therapy into existing chemotherapy backbones for AYA patients, as well as tyrosine kinase inhibitors for both Philadelphia-positive (Ph+) and Ph-like B-ALL. In addition to ongoing attempts to improve up-front treatments by incorporating immunotherapy and targeted approaches, the increased use of next generation sequencing for measurable residual disease evaluation has led to superior risk-stratification and a decreased need to pursue consolidative hematopoietic stem cell transplantation during the first complete remission for many patients.

Creation of a quality improvement collaborative to address adolescent and young adult cancer clinical trial enrollment: ATAQI (AYA trial access quality initiative)

Adolescent and young adult (AYA) participation in cancer clinical trials (CCTs) is suboptimal, hindering further improvements in survival, quality of life, and basic understanding of cancer pathophysiology in this population. Prior studies have identified barriers and facilitators to AYA CCT enrollment; however, few interventional studies have attempted to address these barriers and measure tangible changes. In September 2020, a task force was established to address CCT enrollment barriers at a multi-institutional level utilizing a quality improvement collaborative model for improvement. The AYA Trial Access Quality Initiative was developed with the goal of bring multidisciplinary teams together across multiple sites to learn, apply and share their methods of improvement. It uses a structured process of learning sessions lead by quality improvement and clinical experts who help facilitate learning and problem solving which are followed by action phases. During the pilot phase of the collaboration, one key driver of CCT enrollment in AYA's will be addressed: communication between adult and pediatric oncology by implementation of various interventions at sites. The number of AYAs screened for and enrolled on CCTs will be tracked over the course of the collaborative along with the process measures. It is expected that the interventions will promote engagement of stakeholders in the process of screening AYA oncology patients for eligibility on CCTs. This will hopefully create a favorable environment conducive for increasing enrollment on CCTs and lead to the development of a system-wide quality improvement framework to improve AYA CCT enrollment.

Exploring Barriers to Pediatric Cancer Clinical Trials: The Role of a Networked, Just-in-Time Study Program

The Research to Accelerate Cures and Equity (RACE) for Children Act mandates that newly developed targeted oncology drugs be tested in children when molecular targets are relevant to pediatric cancers. In its first year, the RACE for Children Act was effective in creating novel drug development opportunities for children with cancer; however, significant barriers to clinical trial enrollment persist. Pediatric cancer clinical trials are impacted by challenges surrounding logistics, complexity, and access. As such, there is potential for a networked and centralized study approach to address these barriers. Here we discuss adapting a just-in-time clinical trial approach for adults to serve the pediatric oncology population. Through innovative patient matching solutions leveraging large, real-world datasets with high computational power, the Tempus Integrated Molecular Evaluation (TIME) for Kids Program aims to address barriers in the development of new therapies. This commentary explores the potential for reducing challenges in developing novel pediatric therapeutics, advancing equity in genomic biomarker testing for precision tailored treatment, and improving outcomes for pediatric oncology patients.

Disparities in care and outcomes for adolescent and young adult lymphoma patients

Though survival outcomes among adolescents and young adults (AYAs) with lymphoma have improved over the last three decades, socially vulnerable populations including non-White, low-income, and publicly insured groups continue to trail behind on survival curves. These disparities, while likely the result of both biological and non-biological factors, can be largely attributed to inequities in care over the full cancer continuum. Nationally representative studies have demonstrated that from diagnosis through therapy and into long-term survivorship, socially vulnerable AYAs with lymphoma face barriers to care that impact their short and long-term survival. Thus, improving outcomes for all AYAs with lymphoma requires dedicated study to understand, and then address the unique challenges faced by non-White and low-income lymphoma populations within this age group.

Children's Oncology Group 2023 blueprint for research: Adolescent and young adult oncology

Over the past few decades, 5-year cancer survival has steadily improved for all adolescents and young adults (AYA, 15-39 years at diagnosis) combined. While encouraging, this progress simultaneously highlights a compelling need for improving survival in higher risk AYA subsets and for addressing health outcomes and health-related quality of life (HRQoL) among long-term survivors. The Children's Oncology Group (COG), in collaboration with the National Cancer Institute (NCI) and the adult network groups within the NCI National Clinical Trials Network (NCTN), has developed a large and growing portfolio of therapeutic AYA cancer clinical trials to identify optimal treatment approaches for common AYA cancers. Additional initiatives, led by the COG AYA Oncology Discipline Committee for increasing collaboration between the COG and the adult network groups, optimizing AYA clinical trial enrollment, and standardizing the assessment of HRQoL, have been highly successful to date. Further, NCTN-wide collaborations are currently underway focused on improving survival for AYA malignancies with poor prognosis and, through development of supportive care and care delivery trials, reducing the short- and long-term toxicity caused by cancer treatment. Leveraging the research infrastructure within the NCTN and the NCI Community Oncology Research Program, the COG will continue to champion meaningful advancements in health and survival for AYAs with cancer.

Adolescent and young adult cancers: unmet needs and closing the gaps

PURPOSE OF REVIEW

There is a growing population of adolescent and young adult (AYA, ages 15-39 years) cancer patients and survivors, and the field of AYA oncology is rapidly evolving. Despite an increased focus on survival and quality of life for AYAs, gaps in knowledge remain. The current review focuses on what is known across several domains unique to AYA cancer care as well as areas of improvement and future directions in research and intervention.

RECENT FINDINGS

Due to the developmental stages included in the AYA age range, a cancer diagnosis and treatment can affect relationships, education and employment, finances, and long-term health differently than diagnoses in younger or older populations. Recent studies that have focused on these unique aspects of AYA cancer care, including health-related quality of life (HRQoL), fertility, financial toxicity, barriers to clinical trial enrollment, genetic predisposition, and survivorship care are included in the current review.

SUMMARY

Although studies have described many of the challenges faced by AYAs across the cancer continuum from diagnosis to survivorship, more work is needed, particularly in systematically measuring HRQoL, eliminating barriers to clinical trial enrollment, addressing financial toxicity, and increasing access to fertility preservation and high-quality survivorship care.

Using Teamwork to Bridge the Adolescent and Young Adult Gap

PURPOSE

Individuals diagnosed with cancer age between 15 and 39 years (adolescents and young adults [AYAs]) have not seen improvement in survival compared with children or older adults; clinical trial accrual correlates with survival. Unique unmet needs among AYAs related to psychosocial support and fertility preservation (FP) are associated with health-related quality of life.

METHODS

We enhanced existing structures and leveraged faculty/staff across pediatric/adult oncology to create novel teams focused on AYA (age 15-39 years) care at a single center, with minimal dedicated staff and no change to revenue streams. We aimed to influence domains shown to drive survival and health-related quality of life: clinical trial enrollment, physician/staff collaboration, psychosocial support, and FP. We captured metrics 3 months after patients presented to the institution and compared them before/after Program implementation using descriptive statistics.

RESULTS

Among 139 AYAs (age 15-39 years) from the pre-Program era (January 2016-February 2019: adult, n = 79; pediatric, n = 60), and 279 from the post-Program era (February 2019-March 2022: adult, n = 215; pediatric, n = 64), there was no change in clinical trial enrollment(P ≥ .3), whereas there was an increase in the proportion of AYAs referred for supportive care and psychology (pediatric: P ≤ .02; adult: P ≤ .001); whose oncologists discussed FP (pediatric: 15% v 52%, P < .0001; adult: 37% v 50%, P = .0004); and undergoing FP consults (pediatric: 8% v39%, P < .0001; adult 23% v 38%, P = .02).

CONCLUSION

This team-based framework has effected change in most targeted domains. To affect all domains and design optimal interventions, it is crucial to understand patient-level and facility-level barriers/facilitators to FP and clinical trial enrollment.
