About
The goal of this investigator initiated interventional study is to improve the response to the anticancer treatments (chemotherapy) in people who have previously untreated metastatic pancreas cancer. The main question it aims to answer is:
• Do new types of immune-based therapies, called botensilimab, and balstilimab, when given in combination with chemotherapy consisting of nab-paclitaxel + gemcitabine + cisplatin, and oral medications of chloroquine and celecoxib help patients with previously untreated metastatic pancreatic cancer?
Participants will be administered two immune-based therapies:
Patients will be evaluated when given in combination with:
Full description
This Investigator Initiated Trial (IIT) is proposed based on our experience of obtaining high response rates with chemotherapy or chemotherapy + Programmed cell death protein 1 (PD1) checkpoint inhibitor in patients with previously untreated stage 4 pancreatic adenocarcinoma. However, investigators have hit a barrier as they have not been able to improve the complete response rate above 20% nor improve the 64% 2-year survival rate. For the most part ultimately, the patient's tumor progresses.
Pancreatic cancer relies upon unfolded protein response (UPR) to for survival. The endoplasmic reticulum has stress stressors with a variety of proteins that when activated during stress promote proteostasis and homeostasis which prevents apoptosis. While the UPR is able to achieve homeostasis, under prolonged and unresolved stress, the signaling pathway will lead to apoptosis. In pancreatic cancer, the UPR does play a role as it is upregulated to allow for greater survival. Prior cancer research has been focused on mitigating UPR in cancer through agents such as HSP90 inhibitors but this has not been successful. The hypothesis of this study is that by increasing ER stress and thus UPR that apoptosis occurs in pancreatic cancer by the use of these agents and improve the survival in individuals with advanced pancreatic cancer.
Visually it looks like this with three possibilities when tumor cells are under stress:
Investigators seek to increase ER stress (UPR) to drive that system to apoptosis. To achieve the apoptosis, the investigators seek the maximum treatment approach with maximum chemo immunotherapy to stress the tumor cells (increase of ER stress /UPR) and use 2 agents to help block escape routes a) block autophagy via chloroquine and b) block microenvironment inflammation via celecoxib.

≥ 18 years of age.
Histologically confirmed diagnosis of metastatic pancreatic ductal adenocarcinoma.
Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1 (Appendix A).

Measurable disease on baseline imaging per RECIST 1.1 criteria.
< Grade 2 pre-existing peripheral neuropathy per NCI CTCAE, Version 5.0.
Acceptable coagulation status as indicated by an international normalized ratio (INR)
Adequate organ function defined as the following laboratory values within 7 days prior to first dose of study drugs, except where noted below:
Female patients of childbearing potential (WOCBP) must have a negative urine or serum pregnancy test at screening (within 72 hours of first dose of study drugs).
WOCBP must agree to use highly effective contraceptive measures starting with the screening visit through 6 months after the last dose of study drug(s). Highly effective contraception is defined in Appendix B, Guidance on Contraception, or as stipulated in national or local guidelines. Non-childbearing potential is defined as:
Male patients with a female partner(s) of childbearing potential must agree to use highly effective contraceptive measures throughout the study starting with the screening visit through 6 months after the last dose of study drug(s) is received. Males with pregnant partners must agree to use a condom; no additional method of contraception is required for the pregnant partner.
Willing and able to comply with the requirements of the protocol.
Exclusion criteria
Patients must have received no previous radiotherapy, surgery, chemotherapy, or investigational therapy for the treatment of metastatic disease. Prior treatments in the adjuvant setting with gemcitabine and/or 5-Fluorouracil (5-FU) or gemcitabine administered as a radiation sensitizer are allowed, provided at least 6 months have elapsed since completion of the last dose and development of metastatic disease and no lingering toxicities are present.
History of central nervous system (CNS) metastasis.
Concurrent malignancy (present during screening) requiring treatment or history of prior malignancy active within 2 years prior to the first dose of study drugs (i.e., patients with a history of prior malignancy are eligible if treatment was completed at least 2 years prior to first dose of study drugs and the patient has no evidence of disease). Patients with history of prior early-stage basal/squamous cell skin cancer or noninvasive or in situ cancers who have undergone definitive treatment at any time are also eligible.
QTc Derived From Fridericia's Formula (QTcf) > 450 ms on electrocardiogram (ECG)
Uncontrolled intercurrent illness, including but not limited to clinically significant (i.e., active) cardiovascular disease: cerebral vascular accident/stroke or myocardial infarction within 6 months of enrollment, unstable angina, congestive heart failure (New York Heart Association class ≥ III), or serious uncontrolled cardiac arrhythmia requiring medication. Patients with history of coronary bypass procedure are ineligible.
