Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages Any age
  • All sexes
  • Healthy volunteers accepted
  • Child, Adult, Older adult

Study population: Patients diagnosed with chronic lymphocytic leukemia (CLL) and their living unaffected or affected relatives.

Who may be able to join

  • Patients with histologically confirmed CLL who have living or dead relatives affected with CLL. They must agree to complete a risk factor questionnaire and a family history questionnaire, and to donate a 50mL blood specimen or a buccal specimen.
  • Relatives of the CLL patients who have CLL or other lymphoproliferative disorders (i.e., leukemia \& lymphoma). They must agree to complete a risk factor questionnaire and donate a 50mL blood specimen or a buccal specimen. They will need to sign an authorization to release their medical records so that we can confirm their diagnosis.
  • A sample of unaffected relatives of the CLL patients. They must agree to complete a risk factor questionnaire and donate a 50mL blood specimen or a buccal specimen.

Who cannot join

  • 1) No exclusion criteria

The objective of this study to investigate possible candidate susceptibility genes for familial chronic lymphocytic leukemia (CLL) by identifying and recruiting high-risk families. Through our ongoing study of familial aggregation in CLL kindreds (protocol 2003-0498 'Genetic Study of Chronic Lymphocytic Leukemia'), we have identified CLL patients who have one or more living or dead relative(s) affected with CLL or other leukemias or lymphomas. We will also identify patients in high-risk families from referrals from leukemia clinicians and from self-referrals from patients who learn about our study from the ClinicalTrials.gov website. We plan to invite probands (patients diagnosed with CLL) and their family members with other leukemias and lymphomas and a sample of unaffected relatives to participate in a genetic/linkage study. We will obtain demographic and clinical information along with specimens (blood or buccal samples) from all participants. These families will be part of the Genetic Epidemiology of CLL Consortium, a multicenter, multidisciplinary consortium, based at the Mayo Clinic Cancer Center under the direction of Susan Slager, PhD. This is funded from NCI through a subcontract with Mayo Clinic.

Genotypic data will be analyzed at Mayo Clinic, and coded, de-identified data will be shared with the NIH Genome-Wide Association Studies (GWAS) data repository.

Read the detailed description

This study does not involve taking any medications.

You will be asked to provide study personnel with authorization to request medical records from your physician, the hospital, and/or from other health care facilities where you were diagnosed with cancer. The information gathered will be used to help verify the diagnosis. Study personnel may also need to contact you in the future by phone, mail, or e-mail in order to ask questions about the status of your health.

For this research study, you will be asked to have around 4 tablespoons of blood drawn from a vein in your arm or you will also be asked to provide a sample of cheek cells by spitting into a collection container. The blood and cheek cell samples will be used for special tests to look for genes that may play a role in the development of CLL. You will also be asked to complete a family history questionnaire and a risk factor questionnaire. The family history questionnaire and the risk factor questionnaire will each take 60 minutes to complete. You will need to contact your family members before you send the completed family history questionnaire back to the study staff. You must ask for their permission to send the study staff their contact information. Family members with CLL or other leukemias or lymphomas, as well as a sample of your unaffected family members, will then be contacted by study personnel about participating in the study.

If you live in Houston, or the surrounding area, study personnel can arrange to collect the samples at the time and place of your convenience. If you do not live in the Houston area, sample collection instructions and supplies will be mailed to you. The blood sample may be drawn at your doctor's office, or at a clinic or hospital of your choice. All mailing costs will be paid by the study. No travel to M. D. Anderson will be required.

All blood and cheek cells collected will only be used by researchers involved in this study. Genetic information from the analysis of your blood and cheek cells will be included in a repository of genetic information at the National Institutes of Health, but no personal identifying information will be sent. All information will be kept confidential. Neither you nor your doctor will receive the results of these tests and they will NOT be put in your medical record.

This is an investigational study. Up to 450 participants will be enrolled by M. D. Anderson researchers. A total of 4000 participants will be enrolled in this multicenter study.

Questions about this trial

What is this clinical trial studying?

An observational study of Leukemia, run by M.D. Anderson Cancer Center at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 9 May 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Candidate susceptibility genes for familial chronic lymphocytic leukemia (CLL) (time frame: Data collection over 6 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 9 May 2019.
