A Microdose Evaluation Study of ABY-029 in Primary Sarcoma
A Early Phase 1 study testing ABY-029 in people with Primary Soft-tissue Sarcoma, run by Dartmouth-Hitchcock Medical Center at 1 site in United States.
Trial summary
The primary study objective is to determine if microdoses of ABY-029 (up to 6X) lead to detectable signals (defined as signal-to-noise ratio, SNR ≥10, with the Odyssey NIR scanner in sampled tissues with an EGFR pathology score ≥ 1 based on histological staining and compare SNR to tissues with an EGFR pathology score… Read more about this study

About this study
Official title: A Phase 0 Open Label, Single-center Clinical Trial of ABY-029, an Anti-EGFR Fluorescence Imaging Agent Via Single Intravenous Injection to Subjects With Primary Sarcoma.
The primary study objective is to determine if microdoses of ABY-029 (up to 6X) lead to detectable signals (defined as signal-to-noise ratio, SNR ≥10, with the Odyssey NIR scanner in sampled tissues with an EGFR pathology score ≥ 1 based on histological staining and compare SNR to tissues with an EGFR pathology score < 1).
The secondary study objective is to assess if the spatial patterns of EGFR expression correlate with the tumor targeting of ABY-029 detection by NIR scanner relative to histopathology diagnosis, and other indicators (e.g. proliferation, infiltration, etc.) as the gold standard, and to measure the molecular uptake and concentration of ABY-029 in resected specimens.
Read the detailed description
The investigators plan to enroll a minimum of 6 and a maximum of 12 adult patients with a diagnosis of primary soft-tissue sarcoma in this open label, single center, clinical trial of ABY-029. The study will enroll patients with an EGFR pathology score ≥ 1.
Initial diagnostic biopsy specimens will be analyzed for EGFR positivity by immunohistochemistry following routine diagnostic processing by Pathologist. Patients will be administered a single intravenous dose of ABY-029 1-3 hours before surgery. Following tumor excision, the tumor will be transported to the Pathologist and will be inked and sectioned. Following sectioning the tumor will be imaged using near-infrared imaging systems. Quantitative measurements of fluorophore concentration will be measured for tumors with EGFR pathology score ≥ 1 and compared to those with EGFR pathology score < 1. Quantitative mapping of fluorophore concentration will be correlated with local EGFR concentration and blood vessel density. Upon specimen analysis, fluorophore measurements will be taken from normal, marginal tissues (e.g. skeletal muscle, adipose) in addition to the tumor. Average EGFR concentration and blood vessel density will be determined for each tumor through histological analysis of sections by routine sarcoma protocol and analysis guided by regional variations in ABY-029 concentration based upon near-infrared scan results.
The protocol is not a safety study since no physiological effects are expected at microdose levels of ABY-029. No diagnostic or therapeutic intent is proposed, and administration of the study drug is not intended to alter the extent of planned tumor resection during the surgical procedure.

What is being measured
The primary outcome is the main question the study is designed to answer.
Signal detection
Following tumor excision, the tumor will be inked and sectioned and imaged using a near-infrared scanner and fiber-probe based system. Quantitative measurements of fluorophore concentration will be measured for tumors with EGFR pathology score ≥ 1 and compared to those with EGFR pathology score < 1.
Measured: Day of surgery, up to 1 week after surgery
Secondary outcomes (2)
Correlation of spatial patterns of EGFR expression
Quantitative mapping of fluorophore concentration will be correlated with local EGFR concentration and blood vessel density.
Measured: within 1 week of surgery
molecular uptake and ABY-029 concentration
Fluorophore measurements will be taken from normal, marginal tissues (e.g. skeletal muscle, adipose) in addition to the tumor. Average EGFR concentration and blood vessel density will be determined for each tumor through histological analysis of sections by routine sarcoma protocol and analysis guided by regional variations in ABY-029 concentration based upon near-infrared scan results.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The primary study objective is to determine if microdoses of ABY-029 (up to 6X) lead to detectable signals (defined as signal-to-noise ratio, SNR ≥10, with the Odyssey NIR scanner in sampled tissues with an EGFR pathology score ≥ 1 based on histological staining and compare SNR to tissues with an EGFR pathology score < 1).
The secondary study objective is to assess if the spatial patterns of EGFR expression correlate with the tumor targeting of ABY-029 detection by NIR scanner relative to histopathology diagnosis, and other indicators (e.g. proliferation, infiltration, etc.) as the gold standard, and to measure the molecular uptake and concentration of ABY-029 in resected specimens.

Questions about this trial
What is this clinical trial studying?
A Early Phase 1 study testing ABY-029 in people with Primary Soft-tissue Sarcoma, run by Dartmouth-Hitchcock Medical Center at 1 site in United States.
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 4 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 30 Aug 2021. 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 United States. 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?
Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.
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.
What does the primary outcome measure?
Signal detection (time frame: Day of surgery, up to 1 week after surgery). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 30 Aug 2021.
