Study Overview

Cholesterol Disruption in Combination With the Standard of Care in Patients With Advanced Pancreatic Adenocarcinoma

Cardiovascular diseases and cancers, the two leading causes of death in Canada, require cholesterol to sustain their progression. All cells require cholesterol, but cancer cells have much higher needs to sustain growth, division and metastasis. The availability of new cholesterol-lowering drugs developed to protect patients from heart diseases has resulted in unprecedented low levels of cholesterol. The combination of atorvastatin, ezetimibe and Repatha, which are 3 cholesterol-lowering drugs used in combination, is safe, well tolerated and efficient over years of treatment. Recent reports indicate that abundant cholesterol supplies are required to sustain the progression of pancreatic ductal adenocarcinomas. This proof-of-concept study aims to verify the feasibility, the acceptability and gain preliminary data on adding a cholesterol shortage on top of FOLFIRINOX (standard chemotherapy) in newly diagnosed patients with locally advanced pancreatic adenocarcinomas or metastatic pancreatic adenocarcinomas. It is expected that a drug-induced cholesterol shortage will slow-down or stop the progression of pancreatic adenocarcinomas while increasing the response to chemotherapy.

Study Plan

This section provides details of the study plan, including how the study is designed and what the study is measuring.

Design Details

Primary Purpose:
Treatment

Allocation:
Na

Interventional Model:
Single Group

Masking:
None

Arms and Interventions

Participant Group/ArmIntervention/Treatment
EXPERIMENTAL: Multipathway cholesterol metabolism disruption

Twelve to fifteen patients will receive a combination of daily atorvastatin 40 mg, twice daily ezetimibe 10 mg and evolocumab 420 mg subcutaneously every month. This multipathway cholesterol metabolism disruption will be combined to standard chemotherapy

DRUG: Cholesterol metabolism disruption

  • Cholesterol metabolism disruption using a combination of atorvastatin, ezetimibe and evolocumab in metastatic pancreatic adenocarcinomas
Primary Outcome MeasuresMeasure DescriptionTime Frame
Safety as measured by the rate of adverse eventsTo determine causality and grading severity of each adverse event (AEs) using the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 5.0.2 years
Characterization of dose-limiting toxicitiesTo determine the dose at which no more than 1 out of 6 patients experience a drug related dose-limiting toxicity. To confirm that the combination of daily atorvastatin 40 mg, ezetimibe 10 mg twice daily and monthly evolocumab 420 mg meets the criterion to be the recommended phase II dose (RP2D).2 years

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person’s general health condition or prior treatments.

Ages Eligible for Study:
ALL

Sexes Eligible for Study:
18 Years

Accepts Healthy Volunteers:

    Inclusion Criteria:
    To be eligible to this trial, patients must fulfill the following inclusion criteria:
    1. Have a histologically confirmed, treatment-naive locally advanced and inoperable (LaiPDAC) or metastatic pancreatic ductal adenocarcinoma (mPDAC). 2. Be at least 18 years or older at the time of signing the informed consent. 3. Have a life expectancy of at least 12 weeks. 4. Performance status of 0 or 1 on the Eastern Cooperative Oncology Group (ECOG) scale. 5. Have measurable disease as assessed by RECIST v1.1. 6. Agrees and amenable to a tumor (if deemed safe only) and liver biopsy (all participants) at baseline and on day 42 +/- 3 days. Patient that are anticoagulated at baseline are eligible provided it is deemed safe by the investigator to stop anticoagulation momentarily in order to safely proceed to a biopsy. 7. Eligible to standard-dose FOLFIRINOX as assessed by the principal investigator or a sub-investigator. FOLFIRINOX doses can be adapted according to SOC. 8. Demonstrate normal organ function as defined below. These assessments must be done within 7 days of Cycle 1 Day-7.
