Brief summary: The purpose of this study is to find out if an experimental drug will prevent metastatic pancreatic adenocarcinoma from becoming resistant to standard treatment for the disease.

The names of the study drugs involved in this study are:

* 9-ING-41
* Losartan
* Ferumoxytol
* FOLFIRINOX (made up of 4 different drugs):

  * 5-Fluorouracil (5-FU)
  * Oxaliplatin
  * Irinotecan
  * Leucovorin

Detailed description: This is a multi-institutional, open label, four-arm, non-comparator Phase 2 study of FOLFIRINOX in combination with 9-ING-41 and losartan for the treatment of adult patients with untreated metastatic pancreatic adenocarcinoma (PAC). This research study will begin with a Safety Run-In phase. The Safety Run-In phase will establish the side effects from the study treatment to its safety before beginning the main part of the study. Once that is complete, the main portion of the study will be a Phase II clinical trial.

The U.S. Food and Drug Administration (FDA) has not approved 9-ING-41 as a treatment for pancreatic adenocarcinoma (PAC). The FDA has not approved Losartan for pancreatic adenocarcinoma (PAC), but it has been approved for other uses. The FDA has approved FOLFIRINOX as a treatment option for pancreatic adenocarcinoma (PAC).

This research study involves giving participants an investigational drug called 9- ING-41 with standard anti-cancer drugs. 9-ING-41 stops an enzyme called GSK- 3β from working in cancer cells. Enzymes are proteins that activate and accelerate chemical reactions. The GSK-3β enzyme helps cancer cells to grow and to become resistant to chemotherapy drugs. This study is trying to see if by stopping the activity of GSK-3β using 9-ING-41, it may be possible for standard of care chemotherapy drugs to regain their effectiveness in treating cancers in participants where they have stopped being effective or are effective in only a minority of participants. FOLFIRINOX is a combination of 4 chemotherapy agents that may help shrink pancreatic adenocarcinoma (PAC) tumors. Losartan is a drug that is used to lower blood pressure. In this setting, Losartan has also been demonstrated to suppress TGF-β function in pancreatic adenocarcinoma. Cytokines are molecules that help cells communicate and play a role in immune response. Suppression of TGF-β function is believed to stop the cancer cells from becoming resistant to chemotherapy. This study will evaluate if blocking of GSK-3β activity using 9-ING-41 and blocking of TGF-β function using Losartan can inhibit cancer cell resistance to FOLFIRINOX chemotherapy.

The research study procedures include screening for eligibility and study treatment including evaluations and follow up visits. Participants will receive treatment during three portions of the study: Complete therapy, Maintenance therapy and Transition to complete therapy. After treatment, participants will be followed for up to 5 years.

It is expected that up to 70 people will take part in this research study.

Actuate Therapeutics, a pharmaceutical company, is supporting this research study by providing the study drug 9-ING-41.

The Lustgarten Foundation is providing funding support for this study through a research grant.

Eligibility criteria: Inclusion Criteria:

* Histologically confirmed metastatic pancreatic adenocarcinoma without prior therapy for pancreatic adenocarcinoma.
* Participants must have measurable disease as defined by RECIST 1.1
* Age ≥18 years.
* ECOG performance status ≤1 (Karnofsky ≥ 70%, see Appendix A).
* Participants must have adequate organ and marrow function as defined below:

  * Absolute neutrophil count (ANC) ≥ 1,500/mcL
  * Platelets ≥ 100,000/mcL
  * Total bilirubin ≤ 1.5 institutional upper limit of normal (ULN) if no biliary stenting has been done OR 2.0 x ULN if patient is status post biliary stenting or two downward trending values.
  * AST(SGOT)/ALT(SGPT) \< 5 x institutional ULN.
  * Creatinine ≤ 1.5 mg/dL OR .
  * Creatinine clearance ≥ 30 mL/min (as estimated by Cockcroft Gault Equation)

    (140 - age \[yrs\]) (body wt \[kg\]) Creatinine clearance for males = ------------ (72) (serum creatinine \[mg/dL\])
  * Creatinine clearance for females = 0.85 x male value
* Prior treatment with angiotensin receptor blocker (ARB) for hypertension is allowed. If the patient is randomized to a non-losartan containing treatment arm, the patient must be changed to an antihypertensive medication that is not in the class of angiotensin receptor blocker (ARB).
* Human immunodeficiency virus (HIV)-infected participants on effective anti-retroviral therapy within 6 months are eligible for this trial.
* Participants with evidence of chronic hepatitis B virus (HBV) infection on suppressive therapy, if indicated.
* Participants with a history of hepatitis C virus (HCV) infection must have been treated and cured. Participants with HCV infection who are currently on treatment are eligible even if they do not have an undetectable HCV viral load.
* Participants with treated brain metastases are eligible if follow-up brain imaging after central nervous system (CNS)-directed therapy shows no evidence of progression.
* Participants with new or progressive brain metastases (active brain metastases) or leptomeningeal disease are eligible if the treating physician determines that immediate CNS specific treatment is not required and is unlikely to be required during the first cycle of therapy.
* Participants with a prior or concurrent malignancy whose natural history or treatment does not have the potential to interfere with the safety or efficacy assessment of the investigational regimen are eligible for this trial.
* Participants with known history or current symptoms of cardiac disease, or history of treatment with cardiotoxic agents, should have a clinical risk assessment of cardiac function using the New York Heart Association Functional Classification. To be eligible for this trial, participants should be class 2B or better.
* The effects of treatment are harmful on the developing human fetus are unknown. For this reason, all patients of child-bearing potential must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation and 9 months after completion of mFOLFIRINOX administration. Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately.
* Ability to understand and the willingness to sign a written informed consent document.

Exclusion Criteria:

* Any prior chemotherapy, radiation therapy, immunotherapy, biologic ('targeted') therapy or investigational therapy for pancreas adenocarcinoma. No prior adjuvant or neoadjuvant therapy for localized pancreatic adenocarcinoma is allowed.
* Patients with deleterious or suspected deleterious germline or somatic BRCA-mutated pancreatic cancer.
* Patients with TRK (tropomyosin receptor kinase) fusion-positive cancers.
* Patients with deficient mismatch/microsatellite unstable or high tumor mutation burden cancers.
