What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change From Baseline of Mean of Maximum Tissue to Background Ratio (TBR) in the Qualifying Artery, Following 12 Weeks of Treatment in the Setting of Chronic Statin Therapy

    Qualifying artery was defined as the artery (left or right carotid or ascending aorta) with the highest segmental mean of maximum (max) TBR at Baseline. The TBR of the qualifying segment was to be ≥ 1.6. If more than one artery qualified, the hottest (greatest mean of max TBR) artery was the qualifying artery. Baseline was defined as the value between Days -14 to -1. The change from Baseline was calculated by subtracting the Baseline values from the individual post-treatment values.

    Measured: Baseline (Days -14 to -1) and up to Week 12

Secondary outcomes (9)
  1. Change From Baseline of the 'Most Diseased Segment (MSD)' Average Maximum TBR in the Qualifying Artery Following 12 Weeks of Treatment With GW856553 or Placebo in the Setting of Chronic Statin Therapy

    Most diseased segment (MDS) mean of max TBR was mean of all the slice max TBR that compose the most diseased segment. TBR was derived by dividing the arterial vessel wall SUV (tissue) by the background venous blood pool SUV. Unless noted otherwise, the tissue max SUV value for each ROI was used as inputs to the TBR. Baseline was defined as the value between Days -14 to -1. The change from Baseline was calculated by subtracting the Baseline values from the individual post-treatment values.

    Measured: Baseline (Days -14 to -1) and up to Week 12

  2. Change From Baseline in Blood Concentration of High Sensitivity C-reactive Protein (Hs-CRP)

    CRP is a protein that the liver makes when there is inflammation in the body. It's also called a marker of inflammation, and can be measured with an hs-CRP test. Blood samples were collected to analyze hs-CRP. Baseline was defined as the value on Day 1. The change from Baseline was calculated by subtracting the Baseline values from the individual post-treatment values.

    Measured: Baseline (Day 1) and Days 7, 14, 21, 28, 42, 56, 70, 84

  3. Mean Systolic Blood Pressure (SBP) and Diastolic Blood Pressure (DBP) at Indicated Time Points

    Blood pressure measurements were taken to observe vital signs and included SBP and DBP. SBP and DBP measurements were obtained at Day 1, 7, 14, 21, 28, 42, 56, 70, 84 and follow-up (1-2 weeks post last dose on Day 84).

    Measured: Day 1, 7, 14, 21, 28, 42, 56, 70, 84, 98

  4. Mean Heart Rate at Indicated Time Points

    Vital sign monitoring included heart rate measurement. Heart rate measurements were obtained at Day 1, 7, 14, 21, 28, 42, 56, 70, 84 and follow-up (1-2 weeks post last dose on Day 84).

    Measured: Day 1, 7, 14, 21, 28, 42, 56, 70, 84, 98

  5. Number of Participants With 12-lead Electrocardiogram (ECG) Findings

    All 12-lead ECGs were obtained after the participant had rested in the supine position for at least 15 minutes. All ECGs were evaluated by the principal investigator or designee for any other abnormality of potential clinical importance (PCI). Data for abnormal ECG findings have been reported under abnormal - Not clinically significant (NCS) and Abnormal - Clinically significant (CS) categories. Data only for categories with values have been presented.

    Measured: Days 1, 7, 14, 21, 28, 42, 56, 70, 84, 98

  6. Number of Participants With Clinical Chemistry Abnormalities of PCI

    Clinical chemistry range for PCI was calcium low <1.5 mill mole per litre (mmol/L), high > 3.24 mmol/L; creatinine high 155 mmol/L; glucose low < 2.2 (age: 13-99) mmol/L, high > 27.8 (age: 13-99) mmol/L; phosphorus low < 2.8 mmol/L, high > 6.5 mmol/L; sodium low < 125 mmol/L, high > 150 mmol/L. Categories with values have been presented.

    Measured: Up to Follow-up (Day 98)

  7. Number of Participants With Hematology Abnormalities of PCI

    Hematology range for PCI was: white blood cell count (WBC) low < 1.1 x109/ L; hemoglobin low <71 (age: 18-99) grams per litre (g/L), high >199 (age: 18-99) g/L; hematocrit low 0.201 (age: 18-99) ratio of 1 high 0.599 (age: 18-99) ratio of 1 and platelet count low < 80 x109/ L, high > 500 x109/ L. Categories with values have been presented.

    Measured: Up to Follow-up (Day 98)

  8. Number of Participants With Urinalysis Dipstick Results

    A urine dipstick test is a basic diagnostic tool used to determine pathological changes in a participant's urine in standard urinalysis. Data was analyzed for urine occult blood, urine glucose, urine ketones and urine protein ranging from 2+, trace, 1+, 3+, 1+or 1/4, 3+ or 1 and trace or 1/10, indicating proportional concentrations in the urine sample. Data has been presented for categories with values for positive findings.

    Measured: Day 1, 7, 14, 21, 28, 42, 56, 70, 84, 98

  9. Number of Participants With Adverse Events (AEs) and Serious Adverse Events (SAEs)

    An AE was defined as any untoward medical occurrence that occurred during the course of the trial after study treatment had started. An adverse event was therefore any unfavourable and unintended sign, symptom, or disease temporally associated with the use of study drug, whether or not considered related to the study drug. An SAE is any untoward medical occurrence that at any dose results in death, are life threatening, requires hospitalization or prolongation of hospitalization or results in disability/incapacity, and congenital anomaly/birth defect.

    Measured: Up to Follow-up (Day 98)

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing LOSMAPIMOD 7.5 MG in people with Atherosclerosis, run by GlaxoSmithKline at 4 sites in United Kingdom.

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 18 inclusion and 32 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 17 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 4 sites in United Kingdom. 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 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?

Yes. Results are posted in the registry (first posted 17 Oct 2018). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Change From Baseline of Mean of Maximum Tissue to Background Ratio (TBR) in the Qualifying Artery, Following 12 Weeks of Treatment in the Setting of Chronic Statin Therapy (time frame: Baseline (Days -14 to -1) and up to Week 12). 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 NCT00633022, 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 17 Oct 2018.
