6. Patients must have normal organ and marrow function as defined below:
a. Serum creatinine ≤ 1.5 x ULN.
b. Adequate hepatic function defined by: o total bilirubin level ≤ 1.5 × ULN, o an AST, level ≤ 2.5 × ULN, and an ALT level ≤ 2.5 × ULN (or, for subjects with documented metastatic disease to the liver, AST and ALT levels ≤ 5 × ULN)

8. Women of child-bearing potential or sexually active males must agree to use highly effective contraceptive measures. This applies from starting treatment until at least 16 weeks after the last study drug administration. The investigator or a designated associate is required to advise the patient how to achieve an adequate birth control. Highly effective contraception is defined in the study as methods that achieve a failure rate of less than 1% per year when used consistently and correctly. Such methods include:
I. Combined (oestrogen and progestogen containing) hormonal contraception associated with inhibition of ovulation (oral, intravaginal, transdermal). II. Progestogen-only hormonal contraception associated with inhibition of ovulation (oral, injectable and implantable). III. Intrauterine device (IUD). IV. Intrauterine hormone-releasing system (IUS). V. Bilateral tubal occlusion. VI. Successfully vasectomised partner. VII. Sexual abstinence.

|
E.4 | Principal exclusion criteria |
1. Persisting toxicity related to prior therapy (CTCAE Grade > 1); however alopecia, sensory neuropathy Grade ≤ 2, or other Grade ≤2 AEs not constituting a safety risk based on investigator's judgment are acceptable.
2. Prior treatment with a MEK inhibitor.
3. Known history of testing positive for Human Immunodeficiency Virus (HIV) or known acquired immunodeficiency syndrome.
4. Any significant disease that, in the opinion of the investigator, may impair the patient’s tolerance of study treatment.
5. Patients who are receiving any other investigational agents within 28 days before start of study treatment.
6. Prior organ transplantation including allogenic stem-cell transplantation.
7. Patients with known central nervous system metastases.
8. Active uncontrolled infection, requiring systemic therapy.
9. Clinically significant (i.e., active) cardiovascular disease: cerebral vascular accident/stroke (< 6 months prior to enrollment), myocardial infarction (< 6 months prior to enrollment), unstable angina, congestive heart failure (≥ New York Heart Association Classification Class II), or serious cardiac arrhythmia requiring medication.
10. Severe left ventricular dysfunction as defined by ejection fraction < 45%.
11. Other severe acute or chronic medical conditions including colitis, inflammatory bowel disease, pneumonitis, pulmonary fibrosis or psychiatric conditions including recent (within the past year) or active suicidal ideation or behaviour; or laboratory abnormalities that may increase the risk associated with study participation or study treatment administration or may interfere with the interpretation of study results and, in the judgment of the investigator, would make the patient inappropriate for entry into this study.
12. Known maculopathy of the eye.
13. Known history or current evidence of retinal vein occlusion (RVO) or current risk factors for RVO (e.g. uncontrolled glaucoma or ocular hypertension, history of hyperviscosity or hypercoagulability syndromes).
14. Screening corrected QT interval by Fridericia (QTcF) > 500 msec.
15. Pregnant women and breastfeeding mothers are excluded due to unknown impact on embryos or infants.
16. Known prior severe hypersensitivity to investigational products or any component in its formulation.
17. Concurrent use of medicines known to induce retinal toxicity (e.g. tamoxifen) or QT interval prolonging agents.
18. Known congenital or documented acquired QT prolongation.
19. Uncorrected hypokalemia and/or hypomagnesemia.

E.5 End points |
E.5.1 | Primary end point(s) |
Anti-tumour efficacy of treatment will be primarily measured as 12-week progression free survival (PFS): that is, the percentage of patients free of progression at 12 weeks from starting treatment into the study as determined by radiographic disease assessments per RECIST version 1.1. Planned efficacy assessments will occur by Computed Tomography Thorax, Abdomen and Pelvis (CT TAP) at baseline, 6 weeks, 12 weeks post starting treatment and then q-8 weekly until disease progression or consent withdrawal. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
An Interim Analysis will be performed after the first 10 patients have been enrolled and evaluated for radiological/clinical progression.
A Final Analysis will be performed when the trial has been completed. |
|
E.5.2 | Secondary end point(s) |
SECONDARY ENDPOINTS:
1. Confirmed tumour response rate and duration of response as assessed by RECIST version 1.1.
2. Overall survival
3. To evaluate the safety and tolerability of this regimen as measured by incidence of adverse events reported and toxicity evaluation as per the National Cancer Institute’s Common Terminology Criteria for Adverse Events (NCI CTCAE) version 5.0.
EXPLORATORY ENDPOINTS
1. To establish patient-derived organoids from biopsies of patients with pancreatic cancer being treated with trametinib and hydroxychloroquine before treatment and on treatment.
2. To assess efficiency of treatment and potential emerging resistance mechanisms in patient-derived organoid cultures from patients with pancreatic cancer treated with trametinib and hydroxychloroquine.
3. To deeply characterise resistance mechanisms and design and test potential rescue therapies in patient-derived organoid cultures from patients with pancreatic cancer treated with trametinib and hydroxychloroquine.
4. To further refine the computational resistance models using new methods of multi-omics data integration. |
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
A risk assessment will be performed at the beginning of the study and reviewed on an ongoing basis.
The study will be reviewed on a regular basis by the Cancer Trials Ireland Safety Monitoring Committee while patients are on treatment or in the immediate follow-up period (30 days post last dose).
The analysis of the secondary exploratory endpoints will be performed after the required number of tissue samples are available.
An Interim Analysis will be performed after the first 10 patients have been enrolled and evaluated for radiological/clinical progression.
A Final Analysis will be performed when the trial has been completed. |
