About this study
Official title: A Phase I Study of ABT-751 in Patients With Refractory Hematologic Malignancies
ABT-751 is a new antitumor drug that that interferes with cell division. The goal of this clinical research study is to find the highest safe dose of ABT-751 that can be given as a treatment for refractory hematologic malignancies. The safety and side effects of ABT-751 will also be studied.
Read the detailed description
The current low cure rates in most patients with advanced hematologic cancers indicate the need to identify new agents that can be incorporated with current therapies to improve prognosis. The vinca alkaloids are effective broad-spectrum anti-leukemic drugs. Microtubules are a major structural component of cells. They play a role in cell shape, cellular polarity, cellular movement, intracellular transport and the segregation of chromosomes during mitosis. The cellular microtubule dynamics are highly regulated. As cells enter mitosis, the interphase microtubules disappear and are replaced with a new network of microtubules that interact with the mitotic spindle. Disruption of these new microtubules leads to cell cycle arrest. These important and highly labile microtubule arrays comprising the mitotic spindle are the principal target of oncologic antimitotic compounds. Known antimitotic agents fall into three classes, the vinca alkaloids (vincristine, vinblastine, and vinorelbine), taxanes (paclitaxel and docetaxel), and colchicine-site binders. There are no colchicine-site agents currently approved for cancer chemotherapy. These three classes of compounds have distinct binding sites on the tubulin subunits. ABT-751 is a novel orally administered antimitotic agent that binds to the colchicine site on beta-tubulin and inhibits polymerization of microtubules.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing ABT-751 in people with Hematological Malignancies, 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 5 inclusion and 3 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: finished, as of the sponsor's last update on 31 Oct 2018. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
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?
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 31 Oct 2018.
