Curcumin and Cholecalciferol in Treating Patients With Previously Untreated Stage 0-II Chronic Lymphocytic Leukemia or Small Lymphocytic Lymphoma

March 17, 2024 updated by: Paolo Caimi, MD

A Phase II Study of Curcumin and Vitamin D in Previously Untreated Patients With Early Stage Chronic Lymphocytic Leukemia (CLL) or Small Lymphocytic Lymphoma (SLL)

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.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Detailed 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.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Overall Response Rate Based on NCI-WG (for CLL) and Cheson Criteria (for SLL)
Time Frame: Up to 2 years

The point estimate of the overall response rate (biologic response rate + complete response [CR] + partial response [PR]) with 95% confidence intervals will be calculated using binomial distribution theory.

The time measurement criteria are met for complete response (CR) or partial response (PR) (whichever is first recorded) until the first date that recurrent or progressive disease is objectively documented and assessed
Up to 2 years

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Time to First Cytotoxic Treatment (TFCT)
Time Frame: Up to 2 years

TFCT defined as the time from entry onto study until initiation of treatment with cytotoxic agents because of disease progression.

Kaplan-Meier method and Cox proportional hazard model will be used for the data analysis.

Number of participants still alive at 2 years after treatment discontinuation.
Up to 2 years
