Trial summary

Chloroquine (CQ) is a well known, well tolerated medication that has been used for many years traditionally for arthritis, lupus, and malaria. It has anti-inflammatory properties but is often the drug of choice for arthritis and malaria due to its few side effects. Read more about this study

About this study

Official title: A Phase 2 Randomized, Double-blind, Window of Opportunity Trial Evaluating Clinical and Correlative Effects of Chloroquine as a Novel Therapeutic Strategy in Breast Cancer

Chloroquine (CQ) is a well known, well tolerated medication that has been used for many years traditionally for arthritis, lupus, and malaria. It has anti-inflammatory properties but is often the drug of choice for arthritis and malaria due to its few side effects. Recently, laboratory investigations have proven that CQ may potentially have anti-cancer properties, by inhibiting a process which allows cancers such as breast cancer to continue to grow (a process known as "autophagy"). Therefore, this study will look at how well CQ can inhibit the growth of breast cancers in patients while waiting for surgery.

Read the detailed description

Patients diagnosed with breast cancer can sometimes wait up to 6 weeks for their surgery. The wait leading up to surgery is a potentially long and anxious time. Since no treatment is happening during this period anyway, this study will allow patients to receive CQ during this waiting period. This study will compare CQ treatment before surgery with the standard approach during this time, which is no treatment.

Although CQ is widely used for the treatment of arthritis and malaria, CQ is considered investigational for use in breast cancer.

The study will NOT interfere with the routine assessments as part of the pre-operative care, NOR will it delay the date of surgery.

This study compares the effects of the CQ to placebo. Participants will be randomized 1:1 and be provided with the blinded placebo or QC (500mg daily) during the wait time. Biomarker testing will be performed on the initial biopsy tissue and at the time of surgery as well as blood work. There is also an opportunity for participants to enrol in the optional sample collection for future research.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Effect of a brief course of CQ on tumour proliferation and apoptosis

    We will assess relative changes in proliferative and apoptotic response indices based on Ki67 and TUNEL assays in primary breast cancer biopsies pre- and post-treatment with CQ, as these changes occur more rapidly than gross changes in tumour volume.

    Measured: baseline and at 2-6 weeks, the day of surgery

Secondary outcomes (2)
  1. Measure of Circulating CQ Metabolites

    Plasma samples collected at baseline and at surgery will be assessed for levels of CQ and its metabolite desethylchloroquine (DECQ) by high-performance liquid chromatography (HPLC) as described

    Measured: baseline and at 2-6 weeks, the day of surgery

  2. Autophagic Markers in Cancerous and Stromal Tissue

    Immunohistochemical detection of proteins such as Beclin 1, LC3, and p62 which are required for autophagosome formation have been extensively studied in clinical tumour samples, and will be assessed in participant samples pre and post-CQ treatment.

    Measured: baseline and at 2-6 weeks, the day of surgery

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Chloroquine in people with Breast Cancer and Invasive Breast Cancer, run by Ottawa Hospital Research Institute at 1 site in Canada.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 18 Nov 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Canada. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Angel Arnaout, MD (613-798-5555, anarnaout@toh.on.ca), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Effect of a brief course of CQ on tumour proliferation and apoptosis (time frame: baseline and at 2-6 weeks, the day of surgery). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Nov 2016.
