About this study

Official title: Phase I Study of Single Oral Dose of Se-Methyl-Seleno-L-Cysteine (MSC) in Adult Men

This randomized phase I trial is studying the side effects and best dose of Se-methyl-seleno-L-cysteine in healthy adult men. Studying samples of blood, urine, and toenail clippings in the laboratory from healthy men receiving Se-methyl-seleno-L-cysteine may help doctors learn more about how Se-methyl-seleno-L-cysteine works in the body.

Read the detailed description

PRIMARY OBJECTIVES:

  1. To evaluate the toxicity of MSC, given to healthy adult males as a single oral dose.

SECONDARY OBJECTIVES:

  1. To characterize the pharmacokinetics of single oral doses of MSC in healthy adult male volunteers.

II. To evaluate the baseline selenium content of toenail clippings in healthy adult males.

OUTLINE: This is a multicenter, randomized, placebo controlled, double blind, dose escalation study. Participants are randomized to 1 of 2 arms.

Arm I: Participants receive oral placebo on day 1.

Arm II: Participants receive oral Se-methyl-seleno-l-cysteine (MSC) on day 1. Cohorts of 5 participants receive escalating doses of MSC until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 5 or 2 of 10 patients experience dose-limiting toxicity.

Participants undergo blood, urine, and toenail clipping collection for pharmacokinetic and correlative studies. Samples are analyzed for plasma protein levels of selenium for proteomic and gene expression, molecular fingerprinting by mass spectrometry, and RNA by gene array analysis.

After completion of study treatment, participants are followed at 7-14 days and at 30 days.

Se-methyl-seleno-L-cysteine, placebo, pharmacological study, laboratory biomarker analysis

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Se-methyl-seleno-L-cysteine, pharmacological study and laboratory biomarker analysis in people with Healthy, no Evidence of Disease, run by National Cancer Institute (NCI) at 2 sites 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 11 inclusion and 10 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 14 Nov 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites 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. Some participants in this study may receive a placebo. 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.

What does the primary outcome measure?

Clinical toxicity in healthy adult male volunteers, graded according to the National Cancer Institute Common Toxicity Criteria (NCI CTC) v3.0 (time frame: Up to 30 days). 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 14 Nov 2014.
