Protocol

This section provides details of the study plan, including how the study is designed and what the study is measuring.
Design Details
335 patients to be enrolledTotal number of participants that the clinical trial aims to recruit.
Treatment Study
These studies test new ways to treat a disease, condition, or health issue. The goal is to see if a new drug, therapy, or approach works better or has fewer side effects than existing options.

How participants are assigned to different groups/arms
In this clinical study, participants are placed into groups randomly, like flipping a coin. This ensures that the study is fair and unbiased, making the results more reliable. By assigning participants by chance, researchers can better compare treatments without external influences.

Other Ways to Assign Participants
Non-randomized allocation: Participants are assigned based on specific factors, such as their medical condition or a doctor's decision.
None (Single-arm trial): If the study has only one group, all participants receive the same treatment, and no allocation is needed.

How treatments are given to participants
Participants are divided into different groups, each receiving a specific treatment at the same time. This helps researchers compare how well different treatments work against each other.

Other Ways to Assign Treatments
Single-group assignment: Everyone gets the same treatment.
Cross-over assignment: Participants switch between treatments during the study.
Factorial assignment: Participants receive different combinations of treatments.
Sequential assignment: Participants receive treatments one after another in a specific order, possibly based on individual responses.
Other assignment: Treatment assignment does not follow a standard or predefined design.

How the effectiveness of the treatment is controlled
In a non placebo-controlled study, no participants receive an inert substance (placebo) to compare outcomes. Instead, all participants receive either the experimental treatment or an alternative treatment (often the Standard of Care). This method allows researchers to compare the effects of the experimental treatment with those of a different active intervention, rather than a placebo.

Other Options
Placebo-Controlled: A placebo is used to compare the effects of the experimental treatment with those of an inert substance, isolating the true treatment effect.

How the interventions assigned to participants is kept confidential
Everyone involved in the study knows which treatment is being given. This is typically used when it's not possible or necessary to hide the treatment details from participants or researchers.

Other Ways to Mask Information
Single-blind: Participants do not know which treatment they are receiving, but researchers do.
Double-blind: Neither participants nor researchers know which treatment is given.
Triple-blind: Participants, researchers, and outcome assessors do not know which treatment is given.
Quadruple-blind: Participants, researchers, outcome assessors, and care providers all do not know which treatment is given.

Criteria
14 inclusion criteria required to participate
A diagnosis of B-cell chronic lymphocytic leukemia (B-CLL); according to the National Cancer Institute Working Group (NCI WG) criteria
Relapsed or refractory disease after 1 prior regimen except patients who were refractory to (i.e., progressed on) fludarabine or alemtuzumab therapy. Patients who previously responded (complete response or partial response) to fludarabine or alemtuzumab therapy, but who have relapsed at the time of study entry, may be eligible but response to fludarabine or alemtuzumab therapy must have lasted >12 months (i.e., \>12 months from a documented response to a documented relapse)
Binet stage A, stage B, or stage C or Rai Stage I through IV disease with evidence of progression as evidenced by the presence of one or more of the following
Evidence of progressive marrow failure as manifested by: 1) a decrease in hemoglobin to <11g/dL, or 2) a decrease in platelet count to \<100 x 10\^9/L within the previous 6 months, or 3) a decrease in absolute neutrophil count (ANC) to \<1.0 X 10\^9/L

16 exclusion criteria prevent from participating
Previously treated with >1 prior regimen for B-CLL
Previously treated with a fludarabine plus alemtuzumab (FluCAM) regimen for B-CLL
Positive Coombs test and actively hemolyzing
Absolute neutrophil count (ANC) <1.5 x 10\^9/L or platelet count \<75 x 10\^9/L, unless due to bone marrow involvement

Study Objectives
Primary Objectives

Progression-free survival was defined as the number of days from the date of randomization to the date of first objective documentation of progressive disease (PD) as determined by the treatment-blinded IRRP, or death due to any cause. Results are expressed in months.
Secondary Objectives

Participants were evaluated by the IRRP according to National Cancer Institute (NCI) 1996 response criteria. The best response observed during the study is summarized. Response categories include Complete Response (CR) with normal physical exam, marrow cells and blood values, Partial Response (PR) with a \>= 50% decrease from baseline in lymphocytes, lymphadenopathy and liver or spleen exam, Stable Disease (SD) without significant progression from baseline, or Progressive Disease (PD) with increased size/number of nodes, size of liver or spleen, increase in lymphocytes, aggressive histology.

Overall survival was defined as the time in days from the date of randomization to the date of death due to any cause plus 1 day for all participants. Results are stated in months.

Time to disease progression was defined as the number of days from the date of randomization to the date of first objective documentation of progressive disease as determined by IRRP. Results are stated in months.

Duration of response was analyzed for participants who achieved a complete response (CR) or partial response (PR) and was defined as the number of days from the first date of documented response to the date of progressive disease as determined by IRRP or death due to any cause. Results are stated in months.

Time to alternative therapy was defined as the number of days from the date of randomization to the date of first alternative therapy for chronic lymphocytic leukemia (CLL) or death resulting from any cause. Participants who had not received alternative therapy as of the data cutoff date were censored at the last follow-up visit assessment date plus 1 day. Results are stated in months.

EQ-5D™ is a trademark of the EuroQol Group. EQ-5D™ is a standardized instrument for use as a measure of health outcome. The questionnaire asks about health status along 5 dimensions: mobility, self care, usual activities, pain/discomfort, and anxiety/depression, which are rated at three possible levels (no problems, some problems, extreme problems). The score ranges from best (+1) to worst (-0.59).

The EuroQol Visual Analogue Scale (EQ-VAS) was also used to capture the self-rating of current health status using a visual "thermometer" with the end points of 100 (best imaginable health state) at the top and zero (worst imaginable health state) at the bottom.

Number of participants with adverse events (AEs). AEs were graded by the investigator using the Common Terminology Criteria for Adverse Events (CTCAE) version 3.0 and were assessed for relatedness to study treatment (4 point scale from 'not related' to 'definitely related'). Categories reported include participant counts for treatment-emergent AEs, AEs for infections, serious AEs, AEs causing discontinuation of study drug(s), and deaths. Related AEs for the combination arm can be related to either fludarabine or alemtuzumab.

Clearance of drug from plasma is affected by the absorption, distribution, metabolism and elimination of the drug. Mean systemic clearance of fludarabine is derived from plasma concentration versus time data.

The total volume of distribution (Vss) is the apparent volume in which fludarabine is distributed immediately after it has been injected intravenously and equilibrated between plasma and the surrounding tissues. Total volume of distribution (Vss) of fludarabine is derived from plasma concentration versus time data.

AUC (0-tau) is the area under the plasma concentration curve for fludarabine over the dosage interval (tau).

Cmax is the maximum plasma concentration of fludarabine observed.

MRD negativity in this report was defined by the absence of tumor cells in bone marrow, using 4-color flow cytometry. MRD was assessed in participants with a clinical complete response (CR) or partial response (PR) without recovery of blood counts. MRD represents a very positive outcome.
