Brief Summary:
This phase I trial studies the sides effects and best dose of hydroxychloroquine when given together with trametinib in treating patients with pancreatic cancer that has spread to nearby tissue, lymph nodes or other places in the body and cannot be removed by surgery. Trametinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as hydroxychloroquine, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving trametinib together with hydroxychloroquine may work better in treating patients with pancreatic cancer.

  • Subject is willing to provide a baseline biopsy.
  • EXPANSION COHORT ONLY: Subject must have progressed during or after two standard of care lines of treatment or refused standard of care options.
  • Subject must have computed tomography (CT) measurable disease by Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 criteria
  • Subject must be able and willing to undergo disease assessment while on study and afterwards, if removed for reason other than progression
  • Eastern Cooperative Oncology Group (ECOG) performance status =< 2
  • Absolute neutrophil count (ANC) >= 1.5 x 10^9/L
  • Platelet count >= 100 x 10^9/L
  • Hemoglobin >= 9 g/dL
  • Total bilirubin level =< 1.5 x the upper limit of normal (ULN) range
  • Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels =< 3 x ULN. Patients with liver metastases will be allowed to enroll with AST and ALT levels =< 5 x ULN
  • Estimated creatinine clearance >= 30 mL/min according to the Cockcroft-Gault formula (or local institutional standard method)
  • Negative serum or urine pregnancy test at screening for women of childbearing potential
  • Highly effective contraception for both male and female subjects throughout the study and for at least 4 months after last study treatment administration
  • Recovery to baseline or =< grade 1 Common Terminology Criteria for Adverse Events (CTCAE) version (v)5.0 from toxicities related to any prior treatments, unless adverse event (AE)(s) are clinically nonsignificant and/or stable on supportive therapy
  • Able to provide informed consent and willing to sign an approved consent form that conforms to federal and institutional guidelines

Exclusion Criteria:

  • Subject who have received systemic antineoplastic therapy (including unconjugated therapeutic antibodies and toxin immunoconjugates) or any investigational therapy within 2 weeks or within 5 half-lives of the investigational therapy prior to starting study treatment, whichever is shorter.
  • Subject who have received radiotherapy within 2 weeks prior to the first dose of study treatment. Localized radiation therapy for the treatment of symptomatic bone metastasis is allowed during that timeframe
  • Subjects who have undergone major surgery =< 3 weeks prior to starting study drug or who have not recovered from side effects of such procedure
  • Patients with multiple primary malignancies may be enrolled if non-pancreatic ductal adenocarcinoma (PDAC) tumor(s) does not have the potential to interfere with the safety or efficacy assessment of the investigational regimen as determined by treating investigator and do not require active treatment
  • Known brain metastases or cranial epidural disease unless adequately treated with radiotherapy and/or surgery (including radiosurgery) and stable for at least 4 weeks before first dose of study treatment. Eligible subjects must be neurologically asymptomatic and without corticosteroid treatment at the time of first dose of study treatment
