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.

Clinical Details

Official title: Preventing Invasive Breast Neoplasia With Chloroquine (PINC) Trial

Study design: Allocation: Non-Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Open Label, Primary Purpose: Treatment

Primary outcome: Tumor response evaluated by RECIST criteria as measured by breast MRI.

Secondary outcome:

Evaluate the safety and dosing efficacy of chloroquine in the treatment of patients with DCIS.

Evaluate the effect of therapy on the progenitor cell yield and invasive capacity ex vivo.

Evaluate the effect of treatment on the proteomic and molecular cytogenetic profiles of the DCIS lesions.

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.


Minimum age: 18 Years. Maximum age: N/A. Gender(s): Female.


Inclusion Criteria:

- Patients must have a tissue diagnosis of low, intermediate or high grade ductal

carcinoma in situ or ductal carcinoma in situ with microinvasion.

- Patients with ductal carcinoma in situ undergoing either lumpectomy/radiation or


- Patients must be female at least 18 years of age.

- Patients must have a signed tissue acquisition consent and have at minimum, adequate

samples of primary fresh tissue or blood available for use in this study.

- No history of a previous invasive cancer in the last five years with the exception of

minimally invasive non-melanoma skin cancer.

- Normal liver function based on Liver Function Tests (Total Bilirubin and AST <1. 5 X

Upper Limit of Normal).

- Normal WBC (3. 5-10. 8 x 103µL), PLT (140-400 x 103µL), and HCT (37-52%)

- Potassium within the normal range of 3. 5-5. 3 mEq/L

- Adequate renal sufficiency (serum creatinine <1. 5 mg/dL).

- ECOG performance status 0-2.

- Are able to swallow and retain oral medication.

- No underlying ocular/retinal pathology.

- No medically documented preexisting auditory damage.

- Subjects should be willing to abstain from use of hormonal therapies (e. g. hormone

replacement therapy, oral contraceptive pills, hormone-containing IUDs, and E-string) and chronic NSAID's for the duration of the study (chronic use of NSAID's is defined as a frequency >3 times/week for more than two weeks per year and includes low dose aspirin).

- Subjects with child-bearing potential must agree to use adequate contraception (total

abstinence (no sexual intercourse), use of condom with spermicide or sterilization surgery, including tubal ligation (tubes tied) or hysterectomy (removal of the uterus or womb)) prior to study entry and for the duration of study treatment phase. Should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her study physician immediately. If a subject is of child-bearing potential (women are considered not of child-bearing potential if they are at least one year postmenopausal and/or surgically sterile), she must have a documented negative serum or urine pregnancy test before starting treatment. Exclusion Criteria:

- Patients with a prior history of chemotherapy, hormonal ablation therapy and/or

radiation therapy.

- History of other invasive cancer in the previous 5 years other than minimally

invasive non-melanoma skin cancer.

- Patient desires not to participate in the study.

- Inability to consent.

- Current or recent pregnancy (within 12 months),

- Current use of hormone-containing forms of birth control such as implants (i. e.

Norplants, or injectables ( i. e. depo-provera)

- Currently lactating.

- Patients with history of renal or hepatic insufficiency.

- Current diagnosis for depression, including treatment with an SSRI.

- History of prior treatment with chloroquine for malaria within past 24 months.

- History of allergic reactions to quinalones or chloroquine.

- Active diagnosis of psoriasis or currently receiving treatment for psoriasis.

- History of porphyria.

- History of known Glucose-6-Phosphate Dehydrogenase (G-6-PD) deficiency.

- Alcoholism or hepatic disease.

- History of epilepsy or seizures in the past 20 years.

- History of deep vein thrombosis or pulmonary embolism.

- History of HIV disease and/or treatment with anti-HIV agents.

- Receiving concurrent treatment with prohibited medications (refer to Table 1 for

details on prohibited medications); Examples include: ampicillin, antacids, cimetidine, cyclosporine, kaolin, magnesium trisilicate, coumarin-type anticoagulants, macrolide antibiotics (e. g., clarithromycin, isoniazid, and erythromycin), anti-HIV agents (e. g., ritonavir and delavirdine), antidepressants (e. g. fluoxetine and fluvoxamine), calcium channel blockers (e. g. verapamil and diltiazem), steroids and their modulators (e. g., gestodene, raloxifene, and mifepristone), and several herbal and dietary components (e. g. bergamottin and glabridin).

- Used an investigational drug within 30 days or 5 half-lives, whichever is longer,

preceding the first dose of study medication.
