PRIMARY OBJECTIVE:
I. Conduct a Hybrid Type 1 cluster-randomized, roll-out effectiveness-implementation trial in NCI Community Oncology Research Program (NCORP) community oncology practice sites (N= 500 Black and Latino cancer patients) to evaluate the effectiveness of the EA SUPPORT intervention combining CT navigators and CT research literacy tools in increasing Black and Latino patient referral (primary outcome) and accrual (secondary 
outcome) to NCI-supported CTs. (Phase II)

SECONDARY OBJECTIVES:
II.  Increase participant and provider awareness and knowledge of CTs (exploratory outcomes) while assessing implementations factors.
III. With the Connecting Underrepresented Populations to Clinical Trials (CUSP2CT) data, evaluation, and coordinating center, conduct final site evaluation and disseminate the SUPPORT intervention to NCORP community oncology sites, research bases, and affiliated trial networks. (Phase III)

EXPLORATORY OBJECTIVE:
I. Exploratory outcomes include change in provider referral behavior -, change in provider perceptions of clinical trials, participant referral by provider and participant referral by clinic site, and CUSP2CT selected common measures of:
Ia. Participant CT Awareness and Knowledge; and 
Ib. Provider CT Awareness and Knowledge, assessed at 12 months after the intervention.

OUTLINE: NCORP sites are cluster randomized to 1 of 3 waves to stagger the timing of the start of the SUPPORT intervention on study.

STAGE I (BASELINE CONTROL PERIOD): NCORP sites complete a 4-month baseline usual care control period to support sites in preparing for intervention implementation.

STAGE II (SITE IMPLEMENTATION): NCORP sites participate in SUPPORT intervention over 12 months. Champions and site implementation teams provide the SUPPORT CT Literacy Tool: Health for All website and SUPPORT CT Resource Navigators to patients on study. SUPPORT navigators implement trainings and checklist-based CT referral prompts to NCI-supported CTs for providers and site-based CT recruiters, connect site-based CT staff with resources and support identifying potential CT participants, and identify and address patient-level social determinants of health (SDoH) barriers to cancer CTs. Providers receive CT checklists with specific action items for CT participation. Patients receive CT pocket card with the link to the SUPPORT CT Literacy website and contact information of the SUPPORT navigator.

STAGE III (SUSTAINABILITY & POST-INTERVENTION ASSESSMENTS): Patients and providers complete surveys and may complete an interview at 12 and 18 months post SUPPORT intervention.
