Summary

This study tests an eye injection of ADX-2191 (a form of methotrexate) in 20 adults with primary vitreoretinal lymphoma, a rare eye cancer. The goal is to see if it safely clears cancer cells from the eye. Participants receive injections at different frequencies over 8 weeks.

Why investors are watching

Aldeyra Therapeutics is running a Phase 3 trial of ADX-2191, an injected form of methotrexate, in 20 patients with primary vitreoretinal lymphoma, a rare eye cancer. For a micro-cap company, this small, late-stage readout could determine whether the drug reaches the market and becomes a major revenue source.

If it works: If the trial shows the drug is safe and controls the disease, Aldeyra could gain approval for a treatment with little competition. That result could transform the company's prospects.

If it fails: The trial has only 20 participants, so a negative or unclear result would likely end the program and hurt the company badly. Clinical trials often fail, and this one carries that risk.
