Study of Hydroxychloroquine Before Surgery in Patients With Primary Renal Cell Carcinoma

• Status: Terminated
• Trial end date: 2016-09-01
• Target enrollment: 0
• Participant gender: All

Summary

The main goal of this research study is to determine whether treating patients with renal cell cancer with hydroxychloroquine before surgery can make the cancer easier to kill. Another goal is to see how the study drug affects the body's immune cells which fight cancer cells.

• Phase: Phase 1
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: University of Pittsburgh
• Collaborator: National Institutes of Health (NIH)
• Treatments: Hydroxychloroquine

Criteria

Inclusion Criteria:

• Subjects with suspected primary or metastatic RCC (stage 1-IV) with planned nephrectomy or partial nephrectomy.

• ECOG performance status ≤1

• Normal renal, hepatic, and hematologic function at the time of enrollment as evidenced by:

• Serum creatinine level ≤1.5 the upper limits of normal (ULN)

• Serum total bilirubin level ≤1.5 X ULN

• White blood cell count > or = 3.5x109/ml per ml and platelet count ≥ 100x109 per ml

• Age >18 years.

• Ability to understand and the willingness to sign a written informed consent document.

Exclusion Criteria:

• Subjects who have received chemotherapy for any diagnosis within 12 months prior to study entry.

• Prior use of radiotherapy or investigational agents for RCC.

• Concurrent malignancies with evidence of active or measurable disease except non-melanoma skin cancer

• Inability to adhere to study and/or follow-up procedures

• History of allergic reactions or hypersensitivity to the study drug (hydroxychloroquine) or current therapy with the study drug for other reasons.

• Other concurrent experimental therapy.

• The effects of HC on the developing human fetus are unknown. For this reason 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. All females of childbearing potential must have a blood test or urine study within two weeks prior to registration to rule out pregnancy. Should a woman become pregnant while participating in this study, she should inform her treating physician immediately. If a man impregnates a woman while participating in this study, he should inform his treating physician immediately as well.

• HIV-positive patients are not excluded from the study. However, for patients receiving combination anti-retroviral therapy, the potential impact of pharmacokinetic interactions with HC is unknown. Therefore, HIV-positive patients actively receiving anti-retroviral therapy are excluded from the study.

• Patients with psoriasis are ineligible unless the disease is well controlled and they are under the care of a specialist who agrees to monitor the patient for exacerbations.

• Patients requiring the use of enzyme-inducing anti-epileptic medication that includes:

phenytoin, carbamazepine, phenobarbital, primidone or oxcarbazepine are excluded. Hydroxychloroquine is known to affect the CYP2D6 metabolic pathway. A list of drugs with potential interaction is included in Appendix H.

• Patients with previously documented macular degeneration or diabetic retinopathy are excluded.

• Patients with known glucose-6-phosphate dehydrogenase (GP6D) deficiency

• EKG with QTc >500 msec at baseline (average of 3 determinations at 10 minutes interval). Subjects with ventricular pacemaker for whom QT interval is not measurable will be eligible on a case-by-case basis.
