Study Details

Study Description

Brief Summary

XTR004 is a 18F-labeled myocardial perfusion positron emission tomography tracer use to measure myocardial perfusion and myocardial blood flow. XTR004 binds to the myocytes and targets respiratory chain complex 1 in the mitochondria.This phase I study investigated the safety, biodistribution, radiation dosimetry and Pharmacokinetics of XTR004 in 10 healthy Chinese adults volunteers.

Condition or Disease Intervention/Treatment Phase
  • Diagnostic Test: XTR004
Phase 1

Detailed Description

XTR004 is a 18F-labeled myocardial perfusion PET tracer, the first one developed in China by Sinotau Pharmaceutical Group. XTR004 targets and binds to the mitochondrial complex I protein. XTR004 reflects myocardial function at a molecular level. In pre-clinical studies XTR004 demonstrated high myocardial first-pass extraction and prolonged retention, allowing for early or delayed imaging. XTR004 can be clinically used to measure myocardial perfusion and myocardial blood flow. This Phase I study will be open-labeled, nonrandomized, single center study. Enrolled 10 healthy Chinese adults who meet all of the inclusion and none of the exclusion criteria. Subjects will receive 6-8 mCi of XTR004 via IV injection. Safety and tolerability will be observed. Biodistribution, pharmacokinetics, and dosimetry will be investigated.

Arms and Interventions

Arm Intervention/Treatment
Experimental: XTR004

Single dose 6.0-8.0 mCi intravenous injection of XTR004 and investigation of XTR004 (MPI radiotracer).

Diagnostic Test: XTR004
Single dose intravenous injection of XTR004. Serial whole-body PET scan will be obtain after injection, blood and urine collection after injection for the assessment of pharmacokinetics.

Outcome Measures

Primary Outcome Measures

  1. Physical examination of the major organ systems [up to 14 days post injection]

    Safety observation: Observation of Cardiovascular system (blood pressure, pulse rate, and rhythm), Lungs (respiratory rate, chest expansion, and lung auscultation), Abdominal system (for any tenderness or organ enlargement), Nervous system ( cognitive testing, motor strength and control, including mental status), Musculoskeletal system, and Skin for any abnormalities, after drug injection. To report number of participants with changes in physical examination compared to baseline physical examination obtained before drug injection.

  2. 12-lead Electrocardiography [up to 14 days post injection]

    Safety observation: Observation of ECG electrical activity pattern in the P-wave, PR interval, QRS wave complex, ST segment, and T-wave if associated with any abnormality after drug injection. To observe and report participants with ECG abnormality compared to baseline ECG obtained before drug injection.

  3. Monitoring of body temperature [up to 14 days post injection]

    Safety observation: Vital sign monitoring of body temperature (degrees celsius ) after drug injection. To report changes in body temperature compared to baseline body temperature obtained before drug injection.

  4. Monitoring of respiratory rate [up to 14 days post injection]

    Safety Observation: Vital sign monitoring of respiratory rate (breath per minute) after drug injection. To report changes in respiratory rate compared to baseline respiratory rate obtained before drug injection.

  5. Monitoring of Blood pressure [up to 14 days post injection]

    Safety Observation: Vital sign monitoring of blood pressure (mmHg) after drug injection. To report changes in blood pressure compared to baseline blood pressure obtained before drug injection.

  6. Monitoring of pulse rate [up to 14 days post injection]

    Safety Observation: Vital sign monitoring of pulse rate (beats per minute) after drug injection. To report changes in pulse rate compared to baseline pulse rate obtained before drug injection.

  7. Changes in Laboratory tests [up to 14 days post injection]

    Safety observation: Measurements of routine blood (g/L), routine urine (mg/dL), and blood troponin-I levels (ng/ml) after drug injection. To observe and report changes in routine blood, routine urine, and blood troponin-I levels compared to baseline values obtained before drug injection.

  8. Incidence of adverse events [up to 14 days post injection]

    Safety Observation: Number of participants with adverse events and severe adverse events after drug injection.

Secondary Outcome Measures

  1. Biodistribution of XTR004 after a single dose IV injection. PET scan acquisition; [up to 4.5 hours]

    Whole-body PET scan obtained at the following time points; at 0-60, 120, 150, 240, and 270 minutes, post injection.

  2. Plasma and blood radioactivity analysis [up to 7 hours]

    Venous blood collection of 6ml at 1.5, 3, 5, 10, 30, 60, 120, 240 and 420 minutes for plasma and blood radioactivity analysis, post injection

  3. Urine radioactivity analysis [up to 7.25 hours]

    Urine will be collected up to ~ 7.25 hours to assess for radioactivity, post injection.
