Pipeline and cash

What's next for ALDX, and how long its cash lasts

From Aldeyra Therapeutics’s SEC filings and ClinicalTrials.gov: the company’s own words, the registry’s dates, and arithmetic, not a forecast. Companies often miss their own dates.

Next step the company has named

Q4 2026“Dry Eye Disease (Reproxalap)FDRR meeting with the FDA OND expected the fourth quarter of 2026† Primary Vitreoretinal Lymphoma (ADX-2191)Phase 3 clinical trial initiation expected in 2027‡…”Meeting with the FDA · 8-K, Sep 29

What it means: a meeting with the FDA about the path to an application.

Lead program
ADX-2191
Another trial
Clinical Trial Evaluating Patients With Primary Vitreoretinal LymphomaPhase 3 · Recruiting · 20 people · main data estimated Dec 2026 · NCT07402876

For Pro members: 1 more milestone and 38 filings.

Cash runway

The company says its cash lasts into 2029 (8-K, Sep 29).

That is the company's own estimate. Our arithmetic on its latest balance sheet reads differently, so we show its words, not ours.

For Pro members: the cash on hand, the cash used each quarter, and the math.

Dilution on the horizon

  • Shelf registration (S-3, filed Mar 7, 2024)
  • At-the-market share sales program (424B5, filed Aug 1, 2024)

A shelf lets a company sell shares later; an at-the-market program sells them into the market over time. Neither is a sale by itself.

For Pro members: 1 raise and its amount, and the share count against a year ago.

Insiders

CEO Todd C Brady bought 250,000 shares on Jun 3. 2 more insider trades this year.

From their own Form 4 filings: buys and sales in the market, not awards or shares withheld for tax.

For Pro members: every trade, and Todd Brady’s 3 filings and quotes.

Questions

Straight Answers.

Are the prices delayed?

Only on the public pages, which run at least 15 minutes behind. Pro members, trial included, see real-time prices: the scanner refreshes every 15 seconds, and your watchlist every few seconds, pre-market and after hours included.

Where does the data come from?

Daily bars, quotes, reference data, headlines, and short interest come from Massive, formerly Polygon, a licensed market data vendor. The age of the quotes is shown at the top of every page. Insider trades, notable holders and profits come straight from the SEC. That means Form 4 filings, 13F filings and XBRL financial data on EDGAR. Government filings come from the public STOCK Act and Office of Government Ethics disclosures. The market-wide headlines on the market line also come from the public headline feeds CNBC, MarketWatch and Yahoo Finance publish, shown as the headline, the source and a link to the article. Splits, dividends, and the financial statements on each ticker page come from the vendor's reference data. The 8-K filings on EDGAR are read for the items that move a price. Five years of history is loaded for every stock. So the 200-day and 52-week checks rest on real history. Options flow is not part of the product.

Do I need an account?

Not for the first 24 hours. Tap any green button and you're in, with no email and no password. To keep going, create a free account with Google, Apple, or your email. There is no password to make up.

Is this investment advice?

No. It is a screening tool that scores stocks on the chart, the company's own results, and the news and filings. It does not know your situation and it is not a recommendation to buy or sell anything. Please do your own research.

The price, the score, the chart checks and readings, and the industry rank on this page are delayed at least 15 minutes. Filings are shown as filed, because a disclosure is already days or weeks old when it becomes public. Earnings dates and past reactions are settled sessions.
