About

This phase II trial studies the efficacy (activity), and tolerability of curcumin and cholecalciferol combination in treating patients with previously untreated stage 0-II chronic lymphocytic leukemia or small lymphocytic lymphoma. Curcumin and cholecalciferol may prevent or slow the growth of cancer cells.

Full description

PRIMARY OBJECTIVES:

I. To determine the overall response rate (ORR) based on National Cancer Institute-Working Group (NCI-WG) criteria in chronic lymphocytic leukemia (CLL) or the Cheson criteria in small lymphocytic lymphoma (SLL).

SECONDARY OBJECTIVES:

I. To determine the time to first cytotoxic treatment (TFCT), progression free survival (PFS), and overall survival (OS) using this regimen.

OUTLINE:

Patients receive curcumin orally (PO) daily on days 1-28 and cholecalciferol PO daily on days 8-28 of course 1 and days 1-28 of subsequent courses. Treatment repeats every 28 days for up to 6 courses in the absence of disease progression or unacceptable toxicity. Patients achieving partial response or better may receive treatment for a total of 2 years.

After completion of study treatment, patients are followed up for 30 days and then every 3-6 months for 2 years.

Enrollment: 35 patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Platelet count >= 100,000/mm^3
• Hemoglobin >= 10 g/dL
• Serum creatinine =< 2.0 g/dL or calculated creatinine clearance (CrCl) >= 60mL/min (Cockcroft-Gault method)
• Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) =< 2.5 x institutional upper limit of normal (ULN)
• Bilirubin < 2.0 x ULN, unless subject has Gilbert's disease
• Calcium < 10.1 mg/dL (corrected to serum albumin)
• Females will be either postmenopausal for at least 1 year or surgically sterile for at least 3 months OR females of child-bearing potential must have a negative pregnancy test at screening and agree to take appropriate precautions to avoid pregnancy (double barrier method of birth control or abstinence) from screening through 3 months after the last dose of treatment
• Able to comprehend and willing to sign an Informed Consent Form (ICF)
• Subjects must be off any steroids 7 days prior to the initiation of treatment
• Subjects must be off any curcumin, tumeric, or vitamin D supplements for 14 days prior to the initiation of treatment
• Subjects must be able to take oral medications

Exclusion criteria

• Presence of malignancy (other than the one treated in this study) which required systemic treatment within the past 3 years

• Any indication to start treatment for CLL based on NCI-WG criteria

• Prior therapy for CLL/SLL

• Subjects who are pregnant or breast-feeding; breastfeeding should be discontinued if the mother is treated with curcumin

• Concurrent medical condition which may increase the risk of toxicity, including:

  • Hypercalcemia of any cause
  • Untreated hyperparathyroidism
  • Paget's disease of bone

• Uncontrolled intercurrent illness including, but not limited to, ongoing active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situation that would limit compliance with study requirements as judged by treating physician; subjects receiving antibiotics that are under control may be included in the study

• Inability to take oral medications

• Patients receiving other investigational agent

• History of allergic reactions attributed to compounds of similar chemical or biologic composition to curcumin or vitamin D or other agents used in this study

• Patients on therapeutic anticoagulation, with heparin (or low-molecular weight heparin), warfarin, or a direct thrombin inhibitor as the safety of concurrent administration of curcumin has not been established

• Human immunodeficiency virus (HIV)-positive patients on combination antiretroviral therapy are ineligible
