CA-4948 Added to Standard Chemotherapy to Treat Metastatic or Unresectable Pancreatic Cancer

Inclusion Criteria21

• Patients must have histologically or cytologically confirmed adenocarcinoma of the pancreas that is metastatic or unresectable and for which standard curative or palliative measures do not exist or are no longer effective
• Patients must have had disease progression on or after fluorouracil (5-FU)-based therapy for metastatic or unresectable pancreatic ductal adenocarcinoma (PDAC). If received gemcitabine-based regimen as adjuvant therapy, then gemcitabine and nab-paclitaxel (if used) should be \>12 months from study enrollment. Prior use of gemcitabine/nab-paclitaxel for metastatic or unresectable disease is not allowed
• Age \>= 18 years. Because no dosing or adverse event data are currently available on the use of CA-4948 in combination with gemcitabine and nab-paclitaxel in patients \< 18 years of age, children are excluded from this study
• Eastern Cooperative Oncology Group (ECOG) performance status =\< 2 (Karnofsky \>= 60%)
• Absolute neutrophil count \>= 1,500/mcL
• Platelets \>= 100,000/mcL
• Total bilirubin =\< 1.5 x institutional upper limit of normal (ULN)
• Aspartate aminotransferase (AST) (serum glutamic oxaloacetic transaminase \[SGOT\])/alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase \[SGPT\]) =\< 3 x institutional ULN
• Glomerular filtration rate (GFR) \>= 60 mL/min (based on the calculated Chronic Kidney Disease Epidemiology Collaboration \[CKD-EPI\] glomerular filtration rate estimation)
• Creatine phosphokinase (CPK) elevation at the screening \< grade 2 (creatine phosphokinase \[CPK\] =\< 2.5 ULN)
• Patients on a cholesterol lowering statin must be on a stable dose with no dose changes within 3 weeks prior to study start
• Human immunodeficiency virus (HIV)-infected patients on effective anti-retroviral therapy with undetectable viral load within 6 months are eligible for this trial as long as their anti-retroviral therapy does not have the potential for drug-drug interactions as judged by the treating investigator
• For patients with evidence of chronic hepatitis B virus (HBV) infection, the HBV viral load must be undetectable on suppressive therapy, if indicated
• Patients with a history of hepatitis C virus (HCV) infection must have been treated and cured. For patients with HCV infection who are currently on treatment, they are eligible if they have an undetectable HCV viral load
• Patients with treated brain metastases are eligible if follow-up brain imaging after at least 4 weeks following central nervous system (CNS)-directed therapy shows no evidence of progression
• Patients 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
• Patients 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, patients should be class 2B or better
• Patients must have lesions amenable to research biopsy for those enrolling to the expansion cohort. The biopsy should be deemed feasible and safe for pre-biopsy lesion assessment criteria
• The effects of CA-4948, nab-paclitaxel, and gemcitabine on the developing human fetus are unknown. For this reason and because gemcitabine is known to be teratogenic, embryotoxic, and fetotoxic in mice and rabbits, women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry, for the duration of study participation, and 90 days after completion of CA-4948, nab-paclitaxel, and gemcitabine 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. Men treated or enrolled on this protocol must also agree to use adequate contraception prior to the study, for the duration of study participation, and 90 days after completion of CA-4948, nab-paclitaxel, and gemcitabine administration
• Ability to understand and the willingness to sign a written informed consent document. Participants with impaired decision-making capacity who have a legally-authorized representative (LAR) and/or family member available will also be eligible
• Patients must have measurable disease per Response Evaluable Criteria in Solid Tumors (RECIST) 1.1
