About this study
Official title: A Phase II Trail of Tetrathiomolybdate in Patients With Hormone Refractory Prostate Cancer
Purpose: The aim of this clinical trail is to evaluate Tetrathiomolybdate (TM) in the treatment of hormone refractory prostate cancer.
Read the detailed description
Tetrathiomolybdate or TM, a drug developed for Wilson's Disease, removes copper from the bloodstream. Copper is a key factor in angiogenesis (blood vessel growth)- a process that occurs normally in the body but becomes uncontrolled in cancerous cells. Tetrathiomolybdate essentially wages war against copper, which serves to choke off tumor growth. Realizing the key role of copper in angiogenesis, researchers have begun exploring treatment with Tetrathiomolybdate for different types of cancers. This clinical trial will evaluate the effectiveness of Tetrathiomolybdate in the treatment of patients with hormone refractory prostate cancer. Hormone refractory prostate cancer refers to advanced disease in which the patient no longer responding to conventional hormonal treatment.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
TetrathiomolybdateDrug
| Study group | Role | What they receive |
|---|---|---|
| Tetrathiomolybdate | Experimental | Patients will be started on a dose of 60mg Tetrathiomolybdate at bedtime and 40mg 3 times per day. Receives: Drug: Tetrathiomolybdate |
What is being measured
The primary outcome is the main question the study is designed to answer.
Time to Progression
To determine the time to progression of prostate cancer in patients with androgen-independent prostate cancer treated with tetrathiomolybdate. Disease progression is defined as at least a 20% increase in the sum of the longest diameter of the target lesions. For disease evaluable only by bone scan, the appearance of new lesions was considered evidence of progression. The development of pain in an existing lesion requiring institution of palliative radiotherapy or prescription narcotics was also considered evidence of progression.
Measured: 12 weeks

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Tetrathiomolybdate in people with Prostate Cancer, run by University of Michigan Rogel 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 6 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 21 Jan 2015. 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.
What does the primary outcome measure?
Time to Progression (time frame: 12 weeks). 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 21 Jan 2015.
