Analysis of Tissues From Patients in Trial of Myo-Inositol to Prevent Lung Cancer
A Phase 1 study testing Akt levels in people with AKT, run by National Cancer Institute (NCI) at 1 site in Canada.
Trial summary
This study will examine tissue specimens from patients participating in a trial of high-dose myo-inositol to prevent lung cancer. The trial, conducted at the British Columbia Cancer Agency-Vancouver Cancer Center (BCCA-VCC), includes people who have pre-cancerous changes in the air passages of their lungs.

About this study
Official title: Immunohistochemical Analysis of Human Transbronchial Biopsy Specimens Collected in a Phase I Chemoprevention Trial of Myo-Inositol in Heavy Smokers Conducted Outside the Intramural NCI Program
This study will examine tissue specimens from patients participating in a trial of high-dose myo-inositol to prevent lung cancer. The trial, conducted at the British Columbia Cancer Agency-Vancouver Cancer Center (BCCA-VCC), includes people who have pre-cancerous changes in the air passages of their lungs.
The BCCA-VCC trial was designed to determine side effects of taking large amounts of the food supplement myo-inositol for longer than a month and if the supplement can help smokers stop smoking.

The current study will look at the levels of a substance called Akt in tissue samples obtained from air passages of subjects in the BCCA-VCC trial. Akt is activated by tobacco components and can be found in lung tumor specimens and pre-cancerous lesions. Myo-inositol may affect Akt levels and help prevent progression of pre-cancerous lesions to cancer.
People participating in the BCCA-VCC phase 1 myo-inositol trial are eligible for this study. Tissue samples obtained from air passages of these patients during their participation in that study will be sent to the National Cancer Institute for analysis of Akt levels.
Read the detailed description
Human transbronchial biopsy specimens collected under protocol study numbers CDR0000302633; BCCA-U98-0411; BCCA-C02-0298 will be immunohistochemically stained for activated Akt using phospho-specific antibodies. These samples are part of a phase I chemoprevention trial of myo-inositol being conducted in Vancouver, BC by the British Columbia Cancer Agency in collaboration with the National Cancer Institute (NCI). The transbronchial specimens will be sent to the NCI for analysis of activated AKT. The study aims to determine whether myo-inositol, a putative inhibitor of the upstream kinase phosphatidylinositol 3-kinase, can alter activated Akt levels in smokers with bronchial dysplasia.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
This study will examine tissue specimens from patients participating in a trial of high-dose myo-inositol to prevent lung cancer. The trial, conducted at the British Columbia Cancer Agency-Vancouver Cancer Center (BCCA-VCC), includes people who have pre-cancerous changes in the air passages of their lungs.
The BCCA-VCC trial was designed to determine side effects of taking large amounts of the food supplement myo-inositol for longer than a month and if the supplement can help smokers stop smoking.

People participating in the BCCA-VCC phase 1 myo-inositol trial are eligible for this study. Tissue samples obtained from air passages of these patients during their participation in that study will be sent to the National Cancer Institute for analysis of Akt levels.

Who may be eligible to take part?
The sponsor lists 1 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: finished, as of the sponsor's last update on 23 Mar 2007. 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 Canada. 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?
On the ClinicalTrials.gov record for NCT00342836, which also lists 1 linked publication.
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 23 Mar 2007; AzTrials last refreshed its copy on 8 Nov 2026.
