The purpose of this study is to understand whether a blood-based test called circulating tumor DNA (ctDNA) can detect whether participants are having a desired tumor shrinkage or an undesired lack of tumor shrinkage, and to study whether these levels of ctDNA can be used to make treatment decisions faster than the current standard approach, which is to wait 8 weeks after starting chemotherapy to obtain participant first imaging scans since starting chemotherapy.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Part 1: Early Switch of Chemotherapy Interventional Cohort | Experimental | Participants in this group will receive ctDNA monitoring in combination with standard of care (SOC) of 5-fluorouracil, leucovorin, irinotecan, oxaliplatin (mFOLFIRINOX). Participants will receive standard of care treatment for up to 8 months. Total participation duration is approximately 18 months. |
|
| Part 2 Arm A: Early Switch of Chemotherapy Interventional Cohort | Active Comparator | Participants in this group will receive ctDNA monitoring in combination with standard of care (SOC) of 5-fluorouracil, leucovorin, irinotecan, oxaliplatin (mFOLFIRINOX). After completing three cycles of therapy, participants with methylated-ctDNA fold change of less than threshold determined in Part 1 will continue to receive additional cycles of mFOLFIRINOX for up to 8 months. Participants with methylated-ctDNA fold-change of greater than threshold determined in Part 1 may switch to Part 2 Arm B. Total participation duration is approximately 18 months. |
|
| Part 2 Arm B: Early Switch of Chemotherapy Interventional Cohort | Experimental | Participants in this group will receive ctDNA monitoring in combination with standard of care Gemcitabine and Nab-Paclitaxel therapy, after completion of up to three cycles of mFOLFIRINOX from Part 2 Arm A. Participants will receive standard of care treatment for up to 8 months. Total participation duration is approximately 18 months. |

| 5-Fluorouracil | Drug | Participants will be administered 2400 mg/m^2 of 5-Fluorouracil via continuous intravenous infusion over a 46-hour period beginning on Day 1 of each two-week cycle of standard of care (SOC) modified Folfirinox combination therapy. |
| Measure | Description | Time Frame |
|---|---|---|
| Part 1:Change in ctDNA fold-change at Week 4 | Circulating tumor Deoxyribonucleic Acid (ctDNA) fold-change at week 4 is defined as the ratio between ctDNA quantity at week 4 relative to baseline. The quantity of ctDNA will be measured in ng/mL. At week 4 among participants in Part 1 will be reported as a Tumor Methylation Score (TMS) in plasma samples. The ratio between the TMS at week 4 (TMS4) and the TMS at baseline (TMS0) will be calculated. | Baseline, Up to 4 weeks (after intervention) |
| Part 1: Number of Radiographic Response Status Responders vs. Number of Non-Responders | Radiographic response status among participants in Part 1 will be reported in numbers. Participants will undergo Positron Emission Tomography/Computed Tomography (PET/CT) radiographic imaging scans at the end of week 8. Participants will be subdivided into two groups: responders vs. non-responders to modified Folfirinox treatment. Responders will be defined as the number of participants achieving complete response (CR), partial response (PR) or exhibiting stable disease (SD). Non-responders will be defined as the number of participants exhibiting progressive disease (PD). Response will be evaluated using Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 criteria. | Up to 1.5 years (after intervention) |
| Part 2: Progression-Free Survival (PFS) | Progression-Free Survival (PFS) is defined as elapsed time in months from day 1 of starting second-line (2L) chemotherapy until the date of documented progressive disease (PD) or death. | Up to 3.5 years (after intervention) |
| Measure | Description | Time Frame |
|---|---|---|
| Part 1: Change in ctDNA Tumor Methylation Score (TMS) | Circulating tumor Deoxyribonucleic Acid (ctDNA) Tumor Methylation Score (TMS) is defined as the amount of methylated tumor DNA in the blood. ctDNA TMS will be assessed at baseline, weeks 2, 4, 6, and 8. The Tumor Methylation Score (TMS) score ranges from 10 to 1,000,000. TMS is proprietary score, it does not have units. Higher TMS means higher levels of methylated tumor DNA found in the blood. |

Inclusion Criteria:
Histologically confirmed, metastatic pancreatic adenocarcinoma. Patients with adenosquamous carcinoma and mixed adenocarcinoma/neuroendocrine carcinoma (MANEC) of the pancreas are eligible, but pure neuroendocrine neoplasms are excluded.
Treatment-naïve patients diagnosed with metastatic pancreatic adenocarcinoma.
Must have a detectable circulating tumor deoxyribonucleic acid (DNA) at cycle 1 day 1.
Patients must have a detectable circulating tumor deoxyribonucleic acid (ctDNA) quantity on Northstar Response assay at baseline.
At least one tumor measurable by Computed Tomography (CT) scan or Positron Emission Tomography-Computed Tomography (PET/CT) scan. Measurable disease is defined as at least one lesion that can be accurately measured in at least one dimension (longest diameter to be recorded for non-nodal lesions and short axis for nodal lesions) as >20 mm with conventional techniques or >10 mm with spiral CT scan.
Adult male and female participants (≥ 18 years of age).
Male or non-pregnant and non-lactating female. Men and women with intact reproductive potential must agree to use contraception.
Adequate biological parameters as demonstrated by the following blood counts at Screening (obtained ≤ 21 days prior to enrollment) and at Baseline-Day 0:
Adequate blood chemistry levels at Screening (obtained ≤ 21 days prior to enrollment) and at Baseline-Day 0:
Eastern Cooperative Oncology Group (ECOG) performance status from 0 to ≤ 1.
Must be a modified Folfirinox chemotherapy candidate.
For participants not qualified or able to give legal consent, consent must be obtained from their legally authorized representative (LAR).
Exclusion Criteria:
Patients with pure neuroendocrine neoplasms of the pancreas.
Brain metastases.
Uncontrolled ascites.
Increase of ECOG to > 1 between screening and enrollment.
Active, uncontrolled bacterial, viral, or fungal infection(s) requiring systemic therapy.
History of untreated or uncontrolled HIV and/or Hepatitis B or C infection.
Clinically significant, uncontrolled heart disease and/or cardiac repolarization abnormality, including any of the following:
Grade 2 or greater sensory peripheral neuropathy.
History of chronic diarrhea.
Pregnant or nursing.
Concomitant serious medical or psychiatric illness that, in the opinion of the investigator, could compromise the patient's safety or integrity of the study data.
Concurrently enrolled in any other interventional clinical protocol or investigational trial involving administration of antineoplastic compounds for the treatment of metastatic pancreatic cancer.
Patient is unwilling or unable to comply with study procedures.
Patients with impaired decision-making capacity.
No other medical condition or reason that, in the opinion of the investigator, would preclude study participation.
