NCT05685602

Brief Summary

This phase I trial tests the safety, side effects, and best dose of emavusertib (CA-4948) in combination with gemcitabine and nab-paclitaxel in treating patients with pancreatic ductal adenocarcinoma that has spread from where it first started (primary site) to other places in the body (metastatic) or cannot be removed by surgery (unresectable). CA-4948 is in a class of medications called kinase inhibitors. It works by blocking the action of abnormal proteins called interleukin-1 receptor-associated kinase 4 (IRAK4) and FMS-like tyrosine kinase 3 (FLT3) that signal cells to multiply. This may help keep cancer cells from growing. The usual approach for patients with pancreatic ductal adenocarcinoma is treatment with chemotherapy drugs gemcitabine and nab-paclitaxel. Gemcitabine is a chemotherapy drug that blocks the cells from making DNA and may kill cancer cells. Paclitaxel is in a class of medications called anti-microtubule agents. It stops cancer cells from growing and dividing and may kill them. Nab-paclitaxel is an albumin-stabilized nanoparticle formulation of paclitaxel which may have fewer side effects and work better than other forms of paclitaxel. Giving CA-4948 in combination with gemcitabine and nab-paclitaxel may shrink or stabilize metastatic or unresectable pancreatic ductal adenocarcinoma.

    Cycle 1 day 1 (C1D1) (pre-dose, 0.5, 1, 2, 4, 6, 8 hours [h]), C1D8 (pre-dose), C2D1 (pre-dose, 0.5, 1, 2, 4, 6, 8h), C2D2: (24h post C2D1 dose), C2D8 (pre-dose), C3D1 (pre-dose), C3D17 (+/- 3 d)

Study Arms (1)

Treatment (CA-4948, gemcitabine, nab-paclitaxel)

EXPERIMENTAL

Patients receive CA-4948 PO BID on days 1-21 or 1-28 of each cycle, gemcitabine IV over 30-60 minutes on days 1 and 8 or 1, 8, and 15 of each cycle, and nab-paclitaxel IV over 30-40 minutes on days 1 and 8 or 1, 8, and 15 of each cycle. Cycles repeat every 21 or 28 days in the absence of disease progression or unacceptable toxicity. Patients also undergo CT, tumor biopsies, and blood sample collection throughout the trial.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • 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
  • +6 more criteria

You may not qualify if:

  • Patients who have had chemotherapy or radiotherapy within 4 weeks (6 weeks for nitrosoureas or mitomycin C) prior to entering the study
  • 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 neuropathy, which should resolve to grade 2, or 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)
