Criteria

Inclusion criteria:

1. Histologically confirmed CCA with a documented KRAS mutation.

2. Patients greater than or equal to 18 years of age.

3. Patients must have disease progression that is not amenable to potentially curative treatment.

4. Patients must have received at least one line of chemotherapy.

5. Patients must have at least one measurable disease by RECIST v1.1.

6. Performance status (ECOG) 0-1.

7. Adequate organ baseline function defined as follows: absolute neutrophil count ≥1500 cells/μL, platelet count ≥100,000 cells/μL, hemoglobin ≥9 g/dL, aspartate aminotransferase or alanine aminotransferase less than or equal to 5 × upper limit of normal, estimated glomerular filtration rate ≥60 mL/min, corrected QT interval by Fridericia's (QTcF) interval ≤470 msec.

8. Women of childbearing potential must present with a negative serum pregnancy test and agree to use adequate contraception during the study and until 6 months after the end of treatment. Male patients with women partners of childbearing potential must agree with the contraception procedures of the study protocol.

9. Patients must be able to understand and be willing to comply with the requirements of the study protocol.

10. Patients participate voluntarily and sign informed consent form(s).

Exclusion criteria:

1. Previous treatment with a MEK inhibitor or autophagy inhibitor.

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

1. Cardiovascular disorders: congestive heart failure New York Heart Association ≥ class 2 or left ventricular ejection fraction (LVEF) <50%, arrythmias or cardiac conduction abnormalities, history of coronary disease (including myocardial infarction, unstable angina), history of angioplasty or stenting within 6 months prior to enrollment.

2. Patients who have retinal condition (retinal tear, exudate, hemorrhage) or history of retinal vein occlusion or central serous retinopathy or retinal pigment epithelial detachment.

3. History of interstitial lung disease or pneumonitis.

4. Patients who have clinically significant pleural effusion or ascites.

5. Patients who have neurological condition (e.g., tremor, ataxia, hypotension, confusion), history of seizures or active central nervous system metastases.

6. Impairment of gastrointestinal function or gastrointestinal disease (e.g., diarrhea, active ulcer disease, history of gastrointestinal perforation/hemorrhage, malabsorption or other conditions that under the judgment of the principal investigator (PI) may impair absorption of study drugs).

7. Patients who are taking antineoplastic drugs for concomitant cancer or history of another malignancy with the exception of patients who have been disease-free for at least 3 years.

8. Any other condition that would, in the Investigator s judgment, contraindicate the patients' participation in the clinical study due to safety concerns or compliance with clinical study procedures (e.g., infection, unable to swallow medication, social/psychological issues, etc).

3. Known clinically significant liver disease, including alcoholism, cirrhosis, fatty liver, or inherited liver disease as well as active viral disease including HBV and HCV.

4. Patients with known allergic reaction to quinoline derivatives (e.g., quinine, chloroquine, mefloquine) and/or hypersensitivity to study drugs.

5. Female patients who are pregnant or lactating at the time of enrollment.
