Eligibility Criteria

Eligibility Criteria

Sex: All

Age: 18+

Healthy Volunteers: Not accepted

Inclusion criteria:

1. Histologically confirmed intrahepatic 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 one or two lines 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 ≥1000 cells/μL, platelet count ≥75,000 cells/μL, hemoglobin ≥9 g/dL, aspartate aminotransferase or alanine aminotransferase less than or equal to 3 × 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. Previous treatment with three or more lines of prior chemotherapy.
3. Extrahepatic CCA with recent (within 6 weeks) placement of a stent or episodes of unstable biliary stents (manifest as obstruction, migration of the stent, infevtion or mechanical failure of the stent) within 6 weeks according to investigator's judgement.
4. 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. Uncontrolled arterial hypertension or inadequately controlled arterial hypertension, at the discretion of the investigator, based on an average of = >3 BP readings over = >2 sessions.
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 malignancy other than CCA within 5 years prior to screening, with the exception of malignancies with a negligible risk of metastasis or death (e.g., 5-year OS rate > 90%) such as adequately treated carcinoma in situ of the cervix, non-melanoma skin carcinoma, localized prostate cancer, ductal carcinoma in situ, or Stage I uterine cancer.
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).
5. Known active viral hepatitis, including HBV and HCV.
6. Patients with known allergic reaction to quinoline derivatives (e.g., quinine, chloroquine, mefloquine) and/or hypersensitivity to study drugs.
7. Patients who have not recovered for certain AEs due to previous lines of therpay.
8. Female patients who are pregnant or lactating at the time of enrollment.

Interventions and Outcome Measures

Arms

experimental: GNS561+Trametinib

Phase 1b Dose Finding Patients will receive GNS561 (50mg QD; 100mg QD; 150mg; 200mg QD) and trametinib (2mg QD; 1.5mg QD; 1mg QD) in a dose escalation/de-escalation design to determine the maximum tolerated dose (MTD) of the combination.

Experimental:

Phase 2a Patients will receive GNS561 and trametinib at the recommended dose of the combination determined during Phase 1b

Interventions

GNS561 + Trametinib

GNS561: 50mg, 100mg, 150mg, 200mg and trametinib: 1mg, 1.5mg and 2mg

Primary outcome measure

  • Incidence of dose limiting toxicity (DLT) of GNS561 with trametinib (Phase 1b) [ Time Frame: At the end of Cycle 1 (each Cycle is 21 days) ]
  • Objective response rate (ORR) of the combination of GNS561 with trametinib (Phase 2a) [ Time Frame: Up to 11 months (estimated) ]
