Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
I. To assess dose limiting toxicities and determine the recommended phase 2 dose of emavusertib (CA--4948) in combination with chemotherapy in patients with pancreatic ductal adenocarcinoma.
SECONDARY OBJECTIVES:
I. To observe and record anti-tumor activity. II. To evaluate the safety and tolerability of the combination of CA-4948 and chemotherapy.
III. To determine preliminary signals of efficacy, as measured by objective response rate (ORR), CA-4948 response, progression free survival (PFS), and overall survival (OS).
EXPLORATORY OBJECTIVES:
I. To evaluate pharmacodynamic effect of CA-4948 in combination with chemotherapy.
II. To evaluate pharmacokinetics of CA-4948 in combination with chemotherapy. III. To explore biomarkers and genomic alterations associated with treatment response.
OUTLINE: This is a dose-escalation study of CA-4948 in combination with fixed-dose gemcitabine and nab-paclitaxel followed by a dose-expansion study.
Patients receive CA-4948 orally (PO), gemcitabine intravenously (IV), and nab-paclitaxel IV on study. Patients undergo magnetic resonance imaging (MRI), computed tomography (CT) scan, positron emission tomography (PET) scan, and/or x-ray imaging throughout the trial. Patients also undergo tumor biopsies and blood sample collection during screening and on study.

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
* 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 6 months 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 3 months 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
Exclusion Criteria
* Patients who have not recovered from clinically significant adverse events due to prior anti-cancer therapy (i.e., have residual toxicities \> grade 1) with the exception of alopecia
* History of other malignancy with the exception of 1) malignancies for which all treatment was completed at least 2 years before registration and the patient has no evidence of disease; 2) or known indolent malignancies that do not require treatment and will likely not alter the course of treatment of disease under treatment
* History of allogeneic organ or stem cell transplant
* Current use or anticipated need for alternative, holistic, naturopathic, or botanical formulations used for the purpose of cancer treatment
* Patients who are receiving any other investigational agents
* History of allergic reactions attributed to compounds of similar chemical or biologic composition to CA-4948 or other agents used in study
* Patients receiving any medications or substances that are inhibitors or inducers of CYP3A4 are ineligible due to CA-4948 and nab-paclitaxel. Because the lists of these agents are constantly changing, it is important to regularly consult a frequently-updated medical reference. As part of the enrollment/informed consent procedures, the patient will be counseled on the risk of interactions with other agents, and what to do if new medications need to be prescribed or if the patient is considering a new over-the-counter medicine or herbal product
* Patients with uncontrolled intercurrent illness
* Pregnant women are excluded from this study because gemcitabine is nucleoside analogue with the potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with gemcitabine, breastfeeding should be discontinued if the mother is treated with gemcitabine. These potential risks may also apply to other agents used in this study
* Prolonged Fridericia's correction formula (QTcF) (\> 470 in females, \> 450 in males) on screening electrocardiogram (ECG)
* Gastrointestinal condition which could impair absorption of CA-4948 or inability to ingest CA-4948
* Severe obstructive pulmonary disease or interstitial lung disease
* History of rhabdomyolysis or elevated creatine phosphokinase (CPK)
