Leucovorin for the Treatment of 5 q Minus Syndrome
A Phase 2 study testing Leucovorin in people with 5q Minus Syndrome and Myelodysplastic Syndrome, run by National Institutes of Health Clinical Center (CC) at 1 site in United States.
Trial summary
The 5 q minus syndrome is a condition that occurs due to a missing segment of chromosome 5 in the normal genetic make-up of the cells responsible for forming blood cells. The condition causes patients to have the inability to make blood normally. Read more about this study

About this study
Official title: The Experimental Treatment of Transfusion Dependent 5q Minus Syndrome With Leucovorin
The 5 q minus syndrome is a condition that occurs due to a missing segment of chromosome 5 in the normal genetic make-up of the cells responsible for forming blood cells. The condition causes patients to have the inability to make blood normally. Many patients with this syndrome need transfusions of red blood cells, platelets, and/or white blood cells. Low levels of platelets may cause the patient to bleed easily and low levels of whit blood cells make the patient susceptible to infections. A small number of patients with 5 q minus syndrome develop leukemia, which is often untreatable with chemotherapy.
Researchers believe that one of the genes missing in 5 q minus syndrome is the gene responsible for making folic acid active in the body. Folic acid is a vitamin required for normal blood production.

The purpose of this study to test the effectiveness of a drug called leucovorin for the treatment of 5 q minus syndrome. Leucovorin is an active form of the vitamin folic acid that does not require the missing genes to activate it.
Patients participating in this study may or may not improve with leucovorin treatment. However, the study will improve researchers understanding of the disease and may lead other potential therapies for the disease.
Read the detailed description
The objective of this protocol is to determine whether leucovorin treatment can normalize hematopoietic cell growth and differentiation in patients with 5q- syndrome which may lack the gene for dihydrofolate reductase enzyme.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Leucovorin in people with 5q Minus Syndrome and Myelodysplastic Syndrome, run by National Institutes of Health Clinical Center (CC) at 1 site in United States.
The full registered description is in the About this study section and the official record.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 4 Mar 2008. 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.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00004997, which also lists 3 linked publications.
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 4 Mar 2008.
