Brief Summary

The Sentinel™ Trial is a non-randomized, large-scale observational trial designed to: 1) evaluate the ability of circulating tumor DNA (ctDNA)-based minimal residual disease (MRD) testing to detect recurrence in advance of standard-of-care techniques across solid tumors, and 2) determine the clinical benefit of therapy in ctDNA-positive participants. The study offers the opportunity to 1) serially monitor participants for ctDNA changes, 2) define ctDNA kinetics across tumor and therapy types, 3) identify participants with ctDNA evidence of MRD, and 4) understand the clinical benefit of ctDNA status on treatment outcomes.

Outcome Measures

Primary Outcomes (2)

• Sensitivity and Specificity

  Evaluate ability of ctDNA-based MRD monitoring to detect disease recurrence in advance of SOC recurrence monitoring across solid tumors, as stratified by tumor type and adjuvant therapy status. With sensitivity being the proportion of participants with radiographic recurrence who first had a ctDNA recurrence and specificity being the proportion of participants without radiographic recurrence who did not first have a ctDNA recurrence.

  8 years

• ctDNA Response Rate

  Determine the clinical benefit of treatment in ctDNA-positive participants, as stratified by therapy class (targeted, immuno-, chemo-, etc.), individual therapy, tumor type, stage, and biomarker status. With ctDNA response rate being the proportion of participants with \>50% reduction in mean variant allele frequency (VAF) on-treatment at 3 months compared to baseline VAF.

  8 years

Secondary Outcomes (3)

• Disease Free Survival (DFS): Duration of time between initiation of treatment and radiographic recurrence (investigator assessment) or death

  8 years

• Disease Free Survival (DFS): Duration of time between initiation of treatment and radiographic recurrence (investigator assessment) or death

Other Outcomes (1)

• Examine the interaction of baseline tissue derived biomarkers identified by StrataMRD testing with ctDNA status and kinetics

Study Population

Study participants must meet all the inclusion criteria listed to enroll; 1. Male or female participants ≥ 18 years of age; 2. Confirmed diagnosis of a stage 1-3 solid tumor; 3. Curative surgery or definitive therapy (e.g., chemoradiation, stereotactic body radiation therapy \[SBRT\]) completed \<5 years ago without any current evidence of radiographical or biochemical recurrence, or planned within 28 days of consent; 4. Surplus formalin fixed paraffin embedded tumor specimen available; 5. Able to tolerate venipuncture for blood draws; 6. Primary diagnosis is not glioma or CNS disease; 7. Both the tumor tissue sample and blood sample pass the quantity and quality parameters to allow for a successful MRD test result.
