About this study
Official title: A Study to Evaluate the Use of SOMVC001 (GALA) Vascular Conduit Preservation Solution in Patients Undergoing Coronary Artery Bypass Grafting (CABG)
A prospective randomized, double-blinded, comparative within-person study to evaluate the use of SOMVC001 vs. heparin dosed saline in patients undergoing CABG.
Read the detailed description
Saphenous vein (SV) harvesting will be performed using an open or endoscopic vein harvesting technique. Once harvested, the SV will be divided into segments and these vein segments from each patient to be immersed in one of two blinded solutions: SOMVC001 or heparin dosed saline. The patients will then be randomized and SVG segment allocations will be defined and grafted to the assigned target regions. Imaging, using 64-slice or better MDCT, will be completed 4-6 weeks and 3 months post surgery (CABG) procedure.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
SOMVC001 Vascular Conduit SolutionDevice
SV harvesting will be uniformly performed using an open or endoscopic vein harvesting technique. Once harvested, the SV will be divided into segments and these vein segments from each patient to be immersed in one of two blinded solutions: SOMVC001 or heparin dosed saline. The patients will then be randomized and SVG segment allocations will be defined and grafted to the assigned target regions.

Once harvested, the SV will be divided into segments and these vein segments from each patient to be immersed in one of two blinded solutions: SOMVC001 or heparin dosed saline. The patients will then be randomized and SVG segment allocations will be defined and grafted to the assigned target regions.
| Study group | Role | What they receive |
|---|---|---|
| SOMVC001 Vascular Conduit Solution | Experimental | Each patient will serve as his/her own control because each patient will have two graft segments with one segment immersed in SOMVC001 and the other in heparin dosed saline (Standard solution). Patients will be randomized using a simple random sample allocation scheme. At the time of randomization, patients will be assigned an allocation number. Each randomized patient will be implanted with two SVGs, alternating Target Region A (Circumflex or Diagonal) and Target Region B (Right Coronary System or Diagonal) and alternating (proximal vs. distal) segments of the harvested SV. A randomization schedule will be developed to ensure appropriate randomization allocation of the harvested vein segment being grafted to the targeted regions.

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 1 inclusion and 2 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 12 Jan 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 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.
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?
Mean wall thickness of paired grafts within 100 participants measured at 4-6 weeks and 3 months post-CABG surgery using 64-slice multidetector computed tomography (MDCT) angiography. (time frame: 4-6 weeks to 3 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02272582, 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 12 Jan 2018.
