Head and Neck CancerEarly Phase 1NCT03282461
A Microdose Evaluation Study of ABY-029 in Head and Neck Oncology Surgery
A Early Phase 1 study testing ABY-029 in people with Head and Neck Cancer, 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 wide-field iFI) in sampled tissues with an EGFR (epidermal growth factor receptor) pathology score ≥ 1 based on histological staining.

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 Operable Head and Neck Cancer.
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 wide-field iFI) in sampled tissues with an EGFR (epidermal growth factor receptor) pathology score ≥ 1 based on histological staining.
The secondary study objective is to assess ex vivo the specificity of tumor binding in resected specimens by measuring the corresponding molecular uptake and concentrations using histopathology.
Read the detailed description
The investigators plan to enroll a minimum of 6 and a maximum of 12 adult patients with a diagnosis of operable head and neck cancer in this open label, single center, clinical trial of ABY-029.
Administration of ABY-029 will occur as a single intravenous injection to subjects with operable head and neck cancer approximately 1-3 hours prior to surgery.
Documentation of the tumor with digital photography will be performed at several time points during surgery: pre-resection, at intermediate time points during surgery, and post-resection. White light assessment of the tumor and boundaries will be performed by the surgeon.
Intraoperative optical probe measurements will occur in areas of visible tumor as well as normal appearing tissue. At multiple time points during each surgery and at the discretion of the surgeon, optical probe measurements will be completed with the probe followed by biopsy sampling of the same sites when they are intended for resection. Commonly, these acquisitions will occur at first exposure of the tumor, at the approximate mid-point of tumor resection (when a significant amount of tumor tissue is present in the operative field), at a point nearing but prior to completion of tumor resection (when a small amount of tumor tissue is presumably present), and at the intended completion of tumor resection (when residual tumor may or may not exist). At a data collection time point, optical probe measurements will be performed and archived for analysis and locations may be biopsied when tissue is intended for resection.
Any normal tissue removed as part of surgical procedure will be sampled. Samples may be taken from tissue outside the "antic" tumor volume but resected as part of the procedure along the surgical corridor. All tissue collected will be submitted to pathology for routine processing.
After tissue is removed breadloafed sections will be placed on a fluorescence scanning imager for complete measurement of signal on the exposed surfaces. Pathological analysis for EGFR status will be completed at selected regions around the faces of each breadloaf section.
The protocol is not a safety study since no physiological effects are expected at microdose levels of ABY-029. Rather, doses have been selected to determine if a fluorescence signal can be detected by wide-field imaging technology with a signal-to-noise ratio of 10, which is considered necessary for subsequent assessment of diagnostic performance of ABY-029 as a tumor biomarker sufficient to guide surgical resection in the future. No diagnostic or therapeutic intent is proposed, and study drug administration 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
For each pathology, predictive models of the odds of tumor positivity for biopsies given concentration of ABY-029 will be constructed. Histologically confirmed tumor status from biopsies will be statistically analyzed against the predictive models. The quantitative fluorescence measures will also be assessed for their fit with statistics. The predictive accuracy of the model fit will be summarized through an index.
Measured: Day of surgery, up to 1 week after surgery
Secondary outcomes (1)
Correlation of spatial patterns of EGFR expression
Regions within the wide-field FI images will be classified as tumor on the basis of their fluorescence signals. Continuous, quantitative optical response data will also be available from the intraoperative probe recordings within the fields-of-view. Two-way classification tables will be examined for agreement between the methods for the "tumor" and "not tumor" categories from an individual patient. Statistical analysis will be used to determine if there is agreement with the region classifications.
In a second analysis, histopathology from biopsies taken at FI-positive and negative sites will be classified as non-tumor tissue, solid tumor, infiltrating tumor, or indeterminate. The positive predictive values of these locations within the wide-field images will be calculated for each individual. These data will also be analyzed for sensitivity and specificity of the fluorescence image signatures relative to the reference standard (histopathology).
Measured: within 1 week of surgery

Questions about this trial
What is this clinical trial studying?
A Early Phase 1 study testing ABY-029 in people with Head and Neck Cancer, 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 18 May 2023. 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 18 May 2023.
