Phase II Study of Forodesine in Subjects With Chronic Lymphocytic Leukemia (CLL)

January 18, 2012 updated by: BioCryst Pharmaceuticals
To evaluate the effectiveness and safety of forodesine in CLL patients

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

To investigate the efficacy (complete response [CR] + partial response [PR]) of forodesine in treating subjects with CLL who have failed at least one prior treatment regimen or who are treatment naïve but are either elderly, have poor performance status or are otherwise predicted not to tolerate cytotoxic chemotherapy.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  1. Age 18 years and older
  2. Diagnosis of CLL established by peripheral blood and/or bone marrow examination and using the standard diagnostic criteria.
  3. Subjects with Rai stage III or IV, or earlier stage requiring therapy as determined by the 1996 National Cancer Institute -Working Group (NCI-WG) criterion

  4. Primary resistant (no CR or PR) or progressive disease after response to at least one prior treatment regimen OR treatment naïve subjects who meet at least one of the following criteria.

    1. age >65 years
    2. Eastern Cooperative Oncology Group (ECOG) performance status of 2, 3, or 4
    3. Inability to tolerate standard cytotoxic chemotherapy in the opinion of the treating physician.
  5. ECOG performance status of 0, 1, or 2 (for subjects with primary resistance or progressive disease after response to at least one prior treatment regimen).
  6. Willing to take adequate contraceptive measures (i.e., latex condom, cervical cap, diaphragm, abstinence, etc.) for the entire duration of the study and 3 months after, except for patients who are post menopausal or have prior hysterectomy.
  7. All investigational treatments should have been discontinued for at least 3 weeks prior to the initiation of the study drug.

Exclusion Criteria:

  1. Pregnant or nursing.
  2. Unable or unwilling to sign consent.
  3. Severe, ongoing co-morbid conditions, which would preclude safe delivery of the investigational therapy.
  4. Active serious infections that are not controlled by antibiotics.
  5. ECOG performance status >2 (except for treatment naïve subjects where ECOG performance status 0, 1 or 5 is excluded).
  6. Inadequate renal function: creatinine > or equal to 2.0 unless related to the disease.
  7. Inadequate liver function: bilirubin > or equal to 3.0; transaminases > or equal to 3.0 times the upper limit of normal unless related to the disease.
  8. Known positive test for human immunodeficiency virus (HIV).

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
