About this study
Official title: Preventing Invasive Breast Neoplasia With Chloroquine (PINC) Trial
The purpose of this study is to test the hypothesis that chloroquine will reduce the ability of ductal carcinoma in situ (DCIS) to survive and spread. Participants will receive either chloroquine standard dose (500mg/week) or chloroquine low dose (250mg/week) for 1 month prior to surgical removal of the tumor.
Read the detailed description
The purpose of this study is to test the hypothesis that inhibiting the autophagy pathway in DCIS will reduce the capacity of DCIS to survive and invade. The study will examine the safety and effectiveness of neoadjuvant chloroquine administration for a one month period to patients with low, intermediate grade, or high grade DCIS. We will evaluate whether this treatment will reduce the capacity of DCIS neoplastic cells, existing within the duct, to survive, induce lesion regression, and kill the invasive DCIS progenitor cells.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Chloroquine Standard Dose (500mg/week)Drug
Also called Aralen
Patients will receive chloroquine (500 mg/once a week) for 1 month prior to surgical removal of the DCIS lesion.
Chloroquine Low Dose (250mg/week)Drug
Also called Aralen
Patients will receive chloroquine (250 mg/once a week) for 1 month prior to surgical removal of the DCIS lesion.
Breast BiopsyProcedure or surgery
Also called Biopsy, DCIS, Ductal Carcinoma in Situ
Patients diagnosed with DCIS will undergo a breast biopsy prior to the start of study treatment. This biopsy is entirely voluntary and is not required to remain in the study. The biopsy will allow researchers to study the tissue for biomarkers and to determine how the DCIS tissue changes during treatment. Additional samples of the DCIS tissue will be collected at the time of surgery.
| Study group | Role | What they receive |
|---|---|---|
| Chloroquine Standard Dose (500mg/week) | Experimental | Patients with ER+ or ER- DCIS regardless of histologic grade will be randomly assigned to receive one month standard dose chloroquine (500 mg/week). Receives: Drug: Chloroquine Standard Dose (500mg/week); Procedure: Breast Biopsy |
| Chloroquine Low Dose (250mg/week) | Experimental | Patients with ER+ or ER- DCIS regardless of histologic grade will be randomly assigned to receive one month low dose chloroquine (250mg/week). Receives: Drug: Chloroquine Low Dose (250mg/week); Procedure: Breast Biopsy |
What is being measured
The primary outcome is the main question the study is designed to answer.
Average Change in the Longest Diameter of the Breast MRI Target Lesion
One of the primary outcomes of this study was to measure the impact of weekly chloroquine on the amount of DCIS seen on MRI.The tumor response was evaluated by RECIST criteria. Per Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0) for target lesions and assessed by MRI: Complete Response (CR), Disappearance of all target lesions; Partial Response (PR), >=30% decrease in the sum of the longest diameter of target lesions; Overall Response (OR) = CR + PR The longest diameter of the target lesion or primary area of non-mass enhancement was measured by digital calipers. For one patient, the longest diameter was difficult to measure due to the presence of a significant post biopsy resolving hematoma at the biopsy site. Further correlation was made based on the extent of the pre-treatment microcalcifications and post treatment areas of non-mass enhancement.
Measured: Immediately preceding study drug treatment and again after treatment prior to surgery. The total time interval was up to 8 weeks
Secondary outcomes (3)
Total Number of Treatment-Related Adverse Events
One of the outcomes was to ensure the safety of weekly chloroquine. Patients were followed clinically during the treatment with chloroquine and during their surgery and postoperative period ( including radiation therapy). Patients were verbally assessed for additional symptoms or concerns. Patients were also examined by the provider during treatment and follow up visits to the surgeon.
Measured: The patients were monitored from the time of diagnosis through 6 months of surgical follow up.
Effect of Chloroquine on Proliferating Cell Nuclear Antigen (PCNA) Proliferation Index
We evaluated the effect of therapy on cellular proliferation as measured by the change in proliferating cell nuclear antigen (PCNA) proliferation index. PCNA , which is elevated during the G1/S phase of the cell cycle, may be used as a marker of cellular proliferation. The PCNA proliferation index was measured as the number of PCNA positive stained cells in the DCIS lesion/ total number of cells in the lesion. The change in the PCNA index is equal to the mean PCNA proliferation index pre-treatment minus the mean PCNA proliferation index post-treatment.
Measured: At the time of breast biopsy and again at time of surgery.
Impact of Chloroquine Treatment on the Cell Signaling Kinase Levels in DCIS Lesions.
The study evaluated the effect of chloroquine treatment on the proteomic signaling profiles of the DCIS lesions. Post treatment surgical specimens were evaluated by immunohistochemical staining to measure cell signaling kinase levels for CD68 and HMGB1. CD68 (Cluster Determinant 68) is a marker of macrophages/monocytes in the breast ducts. and HMGB1 (High Mobility Group Box 1) is involved in oxidative stress-mediated autophagy. HMGB1 is a non-histone DNA binding protein. The number of positive cells were quantified and recorded.
.
Measured: At the time of surgery

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing Chloroquine Standard Dose (500mg/week), Chloroquine Low Dose (250mg/week) and Breast Biopsy in people with Carcinoma, Intraductal, Noninfiltrating and DCIS, run by Inova Health Care Services at 4 sites in United States.
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 16 inclusion and 20 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: finished, as of the sponsor's last update on 29 Jun 2021. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 4 sites in United States. 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. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this combined phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
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?
Yes. Results are posted in the registry (first posted 29 Jun 2021). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Average Change in the Longest Diameter of the Breast MRI Target Lesion (time frame: Immediately preceding study drug treatment and again after treatment prior to surgery. The total time interval was up to 8 weeks). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT01023477, which also lists 1 linked publication.
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 29 Jun 2021.
