Summary
Background: Bile duct cancer is cancer of the slender tubes of the biliary tract. These tubes carry bile through the liver. Such cancer tumors often have an abnormal or mutated gene. Researchers think a mix of drugs can slow the progression of gene-mutated cancers of the biliary tract. Objective: To see if using a combination of trametinib and hydroxychloroquine (HCQ) increases the period of time it takes for a person s bile tract carcinoma (BTC) to get worse. Eligibility: Adults age 18 and older with BTC. Design: Participants will be screened with a physical exam, medical history, and cancer history. Their ability to do their normal activities will be assessed. They will have blood and urine tests. They will give a tumor sample. They will have heart tests. They may talk with a heart doctor. They may have an eye exam. They may have a tuberculosis test. They will have computer tomography (CT) scans of the chest, abdomen, and pelvis. They may have magnetic resonance imaging (MRI) scans of the chest, abdomen, pelvis. Participants will repeat some screening tests throughout the study. Participants will take HCQ and trametinib tablets by mouth daily in 28-day cycles. They will have study visits once a month. They will take the drugs until they have bad side effects or the drugs stop working. Participants will have one more tumor biopsies during the treatment. They will have blood taken often. One month after treatment ends, participants will have a safety follow-up visit. Then they will be called or emailed every 6 months for the rest of their life....

Criteria
- INCLUSION CRITERIA:

- Histopathological confirmation of

- biliary tract carcinoma (BTC) OR carcinoma in the setting of clinical and
radiological characteristics which, together with the pathology, are highly
suggestive of a diagnosis of BTC

Note: The term BTC includes intra- or extra- hepatic cholangiocarcinoma (CCA), gallbladder
cancer or ampullary cancer.

- The tumor must have KRAS mutation(s) of clinical significance, confirmed by NCI
Laboratory of Pathology or by FDA approved test.

- Patients must have received or been intolerant of at least one line of chemotherapy.

- Patients must have at least 1 measurable lesion by RECIST version 1.1

- Patients must have disease that is not amenable to potentially curative resection,
ablation or transplantation.

- Age greater than or equal to 18 years.

- Performance status (ECOG) 0-2

- If liver cirrhosis is present, patient must have a Child-Pugh score <7 (Class A)

- Patients must have adequate organ and marrow function as defined below:

- ANC greater than or equal to 1,500/mcL

- platelets greater than or equal to 100,000/mcL

- hemoglobin greater than or equal to 9 g/dL

- total bilirubin if cirrhosis present: Part of Child Pugh requirement. If no
cirrhosis: bilirubin should be less than or equal to 1.5 x ULN

- ALT or AST less than or equal to 5 x ULN.

- Creatinine OR Measured or calculated creatinine clearance (CrCl) (eGFR may also
be used in place of CrCl)*** : < 1.5x institution upper limit of normal OR
greater than or equal to 30 mL/min/1.73 m^2 for participant with creatinine
levels greater than or equal to 1.5 X institutional ULN

Notes:

ALT (SGPT)=alanine aminotransferase (serum glutamic pyruvic transaminase);

AST (SGOT)=aspartate aminotransferase (serum glutamic oxaloacetic transaminase);

GFR=glomerular filtration rate; ULN=upper limit of normal.

***Creatinine clearance (CrCl) or eGFR should be calculated per institutional standard.

- Patients must have at least 1 focus of disease that is amenable to mandatory tumor
biopsies and be willing to undergo this. Ideally, the biopsied lesion should not be
one of the target measurable lesions, although this can be up to the discretion of the
investigators.

- The study drugs are harmful for developing human fetus. For this reason, women of
childbearing potential and men must agree to use adequate contraception (hormonal or
barrier method of birth control; abstinence) at the study entry, for the duration of
study treatment and up to 4 months after the last dose of the study drug(s). 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.

- Patients must be able to understand and be willing to sign a written informed consent.

EXCLUSION CRITERIA:

- Patients who have had standard-of-care anti-cancer therapy within 2 weeks of treatment
initiation or therapy with investigational agents (e.g. chemotherapy, immunotherapy,
endocrine therapy, targeted therapy, biologic therapy, tumor embolization, monoclonal
antibodies or other investigation agents), large field radiotherapy, or major surgery
within 4 weeks of treatment initiation.

- Any unresolved toxicity NCI CTCAE v.5 Grade greater than or equal to 2 from previous
anticancer therapy with the exception of alopecia, vitiligo, and the laboratory values
defined in the inclusion criteria. Patients with Grade greater than or equal to 2
neuropathy will be evaluated on a case-by-case basis.

- Has biliary duct obstruction, unless a treatable, clinically relevant obstruction has
been relieved by internal endoscopic drainage/stenting, palliative by-pass surgery or
percutaneous drainage prior to treatment initiation.

- Patients with known brain metastases are excluded from this clinical trial because of
their poor prognosis and because they often develop progressive neurologic dysfunction
that would confound the evaluation of neurologic and other adverse events.

- Patients with signs of liver failure, e.g. clinically significant ascites,
encephalopathy, or variceal bleeding within six months before treatment initiation.

- History or current evidence of retinal vein occlusion (RVO) or current risk factors
for RVO (e.g. uncontrolled glaucoma or ocular hypertension, history of hyper viscosity
or hypercoagulability syndromes)

- Current evidence of uncontrolled, significant intercurrent illness including, but not
limited to, the following conditions:

- Cardiovascular disorders: Congestive heart failure New York Heart Association
class 3 or 4, unstable angina pectoris, serious cardiac arrhythmias, stroke
(including transient ischemic attack [TIA]), myocardial infarction (MI), or other
ischemic event, or thromboembolic event (e.g., deep venous thrombosis, pulmonary
embolism) within 3 months before treatment initiation

- History of glucose-6-phosphate dehydrogenase (G6PD) deficiency

- History of seizures

- Patients who are planning on embarking on a new strenuous exercise regimen after
first dose of study treatment. Muscular activities, such as strenuous exercise,
that can result in significant increases in plasma creatine kinase (CK) levels
should be avoided while on study treatment

- Patients who have neuromuscular disorders that are associated with elevated CK
(e.g., inflammatory myopathies, muscular dystrophy, amyotrophic lateral
sclerosis, spinal muscular atrophy)

- Impairment of gastrointestinal function or gastrointestinal disease (e.g.,
ulcerative disease, uncontrolled nausea, vomiting, diarrhea, malabsorption
syndrome, or small bowel resection that under the judgment of the principal
investigator (PI) may impair absorption of study drugs)

- Any other condition that would, in the Investigator s judgment, contraindicate
the patient s participation in the clinical study due to safety concerns or
compliance with clinical study procedures, e.g., infection/inflammation,
intestinal obstruction, unable to swallow medication (patients may not receive
drug through a feeding tube), social/psychological issues, etc.

- Screening corrected QT interval by Fridericia's (QTcF) > 500 msec

- Known infection with human immunodeficiency virus (HIV), unless patient is on
effective anti-retroviral therapy with undetectable viral load within 6 months of
treatment initiation

- Known chronic hepatitis B virus, unless hepatitis B virus (HBV) viral load is
undetectable.

- Known history of hepatitis C virus (HCV) infection, unless completed treatment and
cured with undetectable HCV viral load.

- Known prior severe hypersensitivity to study drugs or any component in its
formulations (CTCAE v5.0 grade >= 3).

- Pregnant women are excluded from this study because study therapy can cause fetal
harm. Because there is potential risk for adverse events in nursing infants secondary
to treatment of the mother with study therapy, breastfeeding should be discontinued if
the mother is treated with study drugs.
