Phase 1 Trial of ABY-029 Fluorescence in Patients With High-Grade Glioma

NCT ID: NCT07063693Sponsor: Dartmouth-Hitchcock Medical CenterLast updated: 2026-03-10

Summary

The purposes of the research trial are to study the safety of ABY-029 and to understand how much of the drug is needed to reach brain tumors so it can be visualized best by surgeons. Investigators will do this by comparing two groups of participants that receive different, very small amounts of ABY-029. Investigators will use an imaging system during surgery to record the amount of ABY-029 in the participant's tumor and in the surrounding tissue.

Arms & interventions

DrugABY-029
ABY-029 will be administered via single intravenous injection to subjects with high-grade glioma approximately 1-3 hours prior to surgery. All research procedures will occur during surgery. The research procedures involve image and measurement data collection and biopsy specimen sampling. Research data collection will occur at 3 or 4 time points during surgery using either standard-of-care tools and methods or non-significant risk experimental devices. No follow-up visit will be required of participants. Participants will be monitored for possible adverse events for approximately 30 days by the operating surgeon involved in the clinical trial procedures and through review of participant medical records.

Outcome measures

Primary

Adverse events related to ABY-029
To study the safety of ABY-029, adverse events related to 6X and 10X doses of ABY-029 will be tracked following surgery, and the proportion of study-drug related adverse events at 6X and 10X doses will be compared statistically for significant differences.
Time frame: One month
False negative rate of ABY-029 fluorescence
To measure of diagnostic performance of ABY-029, the false negative rate of ABY-029 fluorescence measured during surgery in tissue samples that are confirmed to be tumor through pathology.
Time frame: Up to three months
