RATIONALE: Studying samples of blood, tumor tissue, and skin in the laboratory from patients with melanoma receiving hydroxychloroquine may help doctors understand the effect of hydroxychloroquine on biomarkers.
PURPOSE: This early phase I trial is studying hydroxychloroquine in patients with stage III or stage IV melanoma that can be removed by surgery.
|Intervention model||single group assignment|
Modulation of markers of autophagy by hydroxychloroquine (HCQ), as measured by p62, Beclin1, LC3, and GRp170 expression
time frame: 1 year
Correlation of steady-state plasma concentration of HCQ with observed trends in induced markers of autophagy
time frame: 1 year
Potential mechanisms of antitumor effect of HCQ, as measured by a reduction in tumor cell proliferation or an increase in apoptosis
time frame: 1 year
Male or female participants from 18 years up to 120 years old.
DISEASE CHARACTERISTICS: - Histologically or cytologically confirmed melanoma - Stage III or IV disease - Has ≥ 2 resectable tumors OR tumor large enough to undergo pre-treatment core needle biopsy - Must be a candidate for curative or palliative surgical resection of disease - Brain metastases allowed provided they were previously treated and have been stable for > 2 weeks PATIENT CHARACTERISTICS: - ECOG performance status 0-2 - Absolute granulocyte count > 1,500/mm³ - Platelet count > 100,000/mm³ - SGOT and SGPT < 2.5 times upper limit of normal (ULN) - Negative pregnancy test - Fertile patients must use effective contraception - No history of any social or medical condition that, in the opinion of the investigator, may interfere with the patient's ability to comply with the study or pose additional or unacceptable risk to the patient - No concurrent serious systemic disorder that, in the opinion of the investigator, would compromise the safety of the patient or compromise the patient's ability to complete the study - No active clinically significant infection requiring antibiotics - No hypertension that cannot be controlled by medication (i.e., diastolic blood pressure > 100 mm Hg despite optimal medical therapy) - No pre-existing thyroid abnormality with thyroid-stimulating hormone that cannot be maintained in the normal range with medication - No known HIV positivity - No psoriasis or porphyria - No known hypersensitivity to 4-aminoquinoline compounds - No retinal or visual field changes from prior 4-aminoquinoline compound use - No known G-6P deficiency - No known gastrointestinal pathology that would interfere with drug bioavailability - No known prior hypersensitivity to hydroxychloroquine or any of its components - No clinically significant bleeding or clotting disorder that would preclude curative or palliative surgery PRIOR CONCURRENT THERAPY: - Recovered from prior therapy - More than 2 weeks since prior cytotoxic or biologic agents (6 weeks for mitomycin or nitrosoureas) - At least 2 weeks since prior surgery, radiotherapy, hormonal therapy, or other drug therapy for melanoma - No concurrent treatment for rheumatoid arthritis or systemic lupus erythematosus - No concurrent disease-modifying anti-rheumatic drugs - No concurrent hydroxychloroquine for treatment or prophylaxis of malaria - No concurrent aurothioglucose or antimalarial agents - No other concurrent chemotherapy, immunotherapy, hormonal therapy, radiotherapy, or surgery for cancer - No other concurrent investigational agents
|Official title||A Phase 0 Trial of Hydroxychloroquine, an Inhibitor of Autophagy, in Patients With Stage III or IV Resectable Melanoma|
|Principal investigator||Janice M. Mehnert, MD|
|Description||OBJECTIVES: Primary - To characterize the effects of hydroxychloroquine (HCQ) on the modulation of markers of autophagy, as measured by p62, Beclin1, LC3, and GRp170 expression, in pre- and post-treatment tumor biopsy samples, skin samples, and peripheral blood mononuclear cell samples from patients with stage III or IV melanoma undergoing palliative or curative surgery. Secondary - To determine whether the steady-state plasma concentration of HCQ correlates with observed trends in induced markers of autophagy. - To determine the potential mechanisms of antitumor effect of HCQ, as measured by a reduction in tumor cell proliferation (Ki-67 and mitotic rate) or an increase in apoptosis (activated caspase-3 and TUNEL assays) in melanoma specimens. OUTLINE: Patients receive oral hydroxychloroquine twice daily for 14 days in the absence of disease progression or unacceptable toxicity. Patients then undergo surgery. Blood, tumor tissue, and skin samples are collected for pharmacokinetic and correlative laboratory studies. Expression of p62, Beclin1, LC3, and GRp170 (autophagy markers) is analyzed.|
