Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Extension to Phase Ib, multi centre, prospective image acquisition trial of [99mTc]ThromboView, at a dose of 0.5 mg labelled with 685-785 MBq 99mTc, in subjects with a diagnosis of at least one pulmonary embolus at a segmental or more proximal pulmonary artery level by CTPA. Eligible and consenting study subjects will receive a single dose of [99mTc]ThromboView prepared using a two-vial formulation and administered by intravenous injection within 72 hours of having undergone a CTPA scan to determine eligibility. Nuclear Medicine imaging scans (both SPECT and Planar) will be performed at 15 minutes, 2 & 4 hours post injection. 24 hour blood and urine sampling performed to assess Radiopharmacokinetc profile. Subjects return for safety assessments at Days 7, 30 and 90 post-injection.

Outcomes
Primary outcome [1] 1451 0
Confirm the safety and tolerability of [99mTc]ThromboView prepared using a two-vial formulation in patients with PE.
Timepoint [1] 1451 0
Safety will be measured from the time of consent to completion of the safety followup period (Day 90).
Secondary outcome [1] 2595 0
1. Further explore optimum parameters for acquisition and processing of [99mTc] ThromboView thoracic SPECT and planar images for detection of PE.
Timepoint [1] 2595 0
Image analysis and independent review will be performed at the completion of recruitment phase of the study.
Secondary outcome [2] 2596 0
2. Explore the pharmacokinetic profile of [99mTc] ThromboView two-vial formulation in subjects with PE.
Timepoint [2] 2596 0
Pharmacokinetic analysis will be performed at the completion of monitoring of the Day 7 followup visit of the last subject enrolled and confirmed evaluable.
Secondary outcome [3] 2597 0
3. Continue to develop preliminary guidelines for the interpretation of thoracic Single Photon Emission Computed Tomography (SPECT) and planar images acquired following injection of [99mTc] ThromboView.
Timepoint [3] 2597 0
This outcome will be measured at the final Study Steering Committee meeting where results of all Image interpretation is performed.

Eligibility

Key exclusion criteria
1. Subject is unwilling/unable to consent.2.Prior parenteral exposure to murine, chimeric, or humanized antibodies. 3.Inability to undergo the required imaging protocol, due to either subject factors or equipment limitations.4.Therapeutic anticoagulation for more than 72 hours prior to the planned time of ThromboView administration.5.Thrombolytic therapy during the current presentation.6.Prior imaging studies or treatment with radiolabelled isotopes (within relative time decay windows). 7.Prior non-imaging, non-therapeutic study with 131-I within last 2 weeks.8.Life expectancy less than 90 days.9.Previous participation in the present study or in any previous ThromboView studies. Current enrolment in a clinical trial for another investigational agent.10.Geographic inaccessibility that precludes follow-up visits.11.Renal dysfunction: serum creatinine > 1.5 x upper limit of normal range.12.Hepatic dysfunction: serum transaminases > 3 x upper limit of normal range.13. Current pregnancy or lactation, or conception intended within 3 months of enrolment.14.Subjects with previously documented PE.15.Any primary or metastatic malignancies involving the lungs or pleura.16.Diffuse active inflammatory or infectious pulmonary conditions (involving >2 segments of a lung).17.Any other medical condition which in the opinion of the investigator would prevent successful completion of the trial.18.Likely inability to gain IV access as per protocol.
