Company

Company overview

Aldeyra Therapeutics is developing reproxalap for dry eye disease and allergic conjunctivitis, alongside other experimental treatments for eye and immune-mediated diseases. It has no approved products and earns no revenue from drug sales; it cannot sell its candidates before regulatory approval. Share sales and borrowing have provided most of its funding, and it needs additional capital to complete development and prepare for commercialization.

AbbVie has paid Aldeyra for an exclusive option to enter a reproxalap collaboration, but had not exercised it as of February 2026. If the companies enter the agreement, AbbVie would pay upfront and milestone payments, share U.S. commercialization profits and losses with Aldeyra, and pay royalties on sales outside the United States. This planned income path depends on approval and AbbVie choosing to proceed. Without that collaboration, Aldeyra would remain responsible for funding reproxalap development and commercialization, either alone or with another partner.

Aldeyra’s prospects hinge on FDA approval of reproxalap, whether AbbVie takes up its option to commercialize the drug, and access to capital before product revenue begins.

  • AbbVie could fund Aldeyra’s reproxalap and help develop, manufacture and sell it if it takes up its licensing option and signs the collaboration agreement, paying $100 million upfront less prior payments, with potential milestone payments and shared U.S. profits and losses. The key news is whether AbbVie exercises within ten business days after any FDA approval of reproxalap for dry eye; as of February 27, 2026, it had not.
