Suprachoroidal bel‑sar (AU‑011) for metastases in the choroid
Official title: A Phase 2, Open-Label, Dose Escalation Trial Assessing the Safety, Tolerability, and Treatment Effect of Belzupacap Sarotalocan (AU-011) With Suprachoroidal Administration in Subjects With Metastases to the Choroid
Run by Aura Biosciences · NCT06643884 · Data updated 2026-11-12
This trial will try injecting bel‑sar (AU‑011) under the eye's choroid to see if it is safe and tolerable for people with choroidal metastases from solid tumors.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults with at least one histologically or cytologically confirmed metastasis to the choroid in the study eye, without active ocular infection and not planning changes to systemic anti‑cancer therapy during treatment.
✕Probably not a fit
Patients with active ocular infection or disease, brain metastases requiring radiation, or those planning to change or add systemic antineoplastic therapy are unlikely to qualify or benefit from this protocol.

What this trial studies
This is an open‑label, Phase 2 dose‑escalation trial testing four dose levels of bel‑sar (AU‑011) delivered suprachoroidally using a microinjector, with adjunct laser as specified in the protocol. Participants will receive one to two treatment cycles and be monitored for safety, ocular tolerability, and adverse events. Subjects must have at least one histologically or cytologically confirmed metastasis to the choroid in the treated eye and no active ocular infection or brain metastases requiring radiation. The trial is being conducted at three US academic ophthalmology centers and focuses on local delivery to limit systemic exposure.
Why it matters
Potential benefit: If successful, this approach could offer a localized treatment option to control choroidal metastases while minimizing systemic side effects and potentially preserving vision.
How similar studies have gone: Localized ocular delivery approaches have shown promise in early‑phase work for other intraocular tumors, but suprachoroidal dosing of bel‑sar for choroidal metastases represents a novel application with limited prior data.
