Biological Effects of Agent on PAR-4 Levels With Resected Solid Tumors
The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.
Know the risks and potential benefits of clinical studies and talk to your health care provider before participating.
Read our disclaimer for details.
Hydroxychloroquine will be administered on an outpatient basis within 12 weeks after primary surgery followed by adjuvant chemotherapy /or radiation therapy (if needed). Hydroxychloroquine will be administered orally at a dose of 400 mg daily for 90 days. Subjects will receive HCQ every day.
Choosing to participate in a study is an important personal decision. Talk with your doctor and family members or friends about deciding to join a study.

Layout table for eligibility information
Ages Eligible for Study:
18 Years and older (Adult, Older Adult)
Sexes Eligible for Study:
Accepts Healthy Volunteers:
Histologically confirmed solid tumor that is surgically resected
Have completed all planned adjuvant therapy or are not planned for adjuvant therapy
Age ≥18 years
ECOG performance status ≤1 (Karnofsky ≥80%)
Patients must be able to ingest oral medications (crushing and administering via PEG tube is acceptable)
Patients must have normal organ and marrow function as defined below:
absolute neutrophil count ≥1,500/mcL
total bilirubin Less than 1.5 x ULN
AST(SGOT)/ALT(SGPT) ≤2.5 × institutional upper limit of normal
creatinine within normal institutional limits OR creatinine clearance ≥50 mL/min/1.73 m2 for patients with creatinine levels above institutional normal
The effects of hydroxychloroquine on the developing human fetus are unknown. For this reason, and because anti-malarial agents as well as other therapeutic agents used in this trial are known to be teratogenic, women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation. Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately. Men treated or enrolled on this protocol must also agree to use adequate contraception prior to the study, for the duration of study participation, and four months after completion of hydroxychloroquine administration.
Men treated or enrolled on this protocol must also agree to use adequate contraception prior to the study, for the duration of study participation, and four months after completion of hydroxychloroquine administration.
Ability to understand and the willingness to sign a written informed consent document.
Approval for hydroxychloroquine treatment by an eye doctor, based on a screening eye exam.
Patients with metastatic cancer and/or cancer that is not amenable to surgery.
Patients with significant malabsorption as determined by the treating physician.
Patients who are receiving any other investigational agents.
Patients with known brain metastases are excluded from this clinical trial because of their poor prognosis and because they often develop progressive neurologic dysfunction that would confound the evaluation of neurologic and other adverse events. Patients with primary brain tumors amenable to surgery are allowed on this protocol.
History of allergic reactions attributed to compounds of similar chemical or biologic composition to hydroxychloroquine or received HCQ in the past six months.
Caution should be taken with the use of hydroxychloroquine and any drugs known to interact with it (Appendix B). Because the lists of these agents are constantly changing, it is important to regularly consult a frequently updated list such as http://medicine.iupui.edu/clinpharm/ddis/table.aspx
Patients with uncontrolled intercurrent illnesses including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.
Pregnant women are excluded from this study.
HIV-positive patients on combination antiretroviral therapy are ineligible
Patients that are on enzyme-inducing anti-epileptic medications.
