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

From Atrium 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

End of 2026“Clinical site initiation activities are currently underway, and Atrium expects the first participant to be enrolled by the end of 2026.”Trial start · 8-K, Jul 14

What it means: when a trial begins, or reaches the stage the company named.

A trial underway
ATR 1072 in Participants With PRKAG2 SyndromePhase 1/2 · Recruiting · 37 people · main data estimated May 2028 · NCT07738107

For Pro members: 6 filings.

Cash runway Jun 30 balance sheet

$264M in cash

Fewer than four quarters of cash flow are on file.

What it means: a runway is counted only when each of the last four quarters used cash. The company's own estimate is “through 2028” (8-K, Oct 8).

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

Dilution on the horizon

No shelf registration of its own or at-the-market program on file in the last three years.

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: the amounts, and the share count against a year ago.

Insiders

No open-market buys or sales by its officers or directors in their filings of the last 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 Kathleen Gallagher’s 5 filings and quotes.

The gap is the next open against the close before the report; the reaction is where that session closed. RNA closed higher after 1 of its last 2. Past behavior, not a forecast.

Report dates and past reactions come from sessions that have already closed, so none of these figures move.

Straight Answers

Are the prices delayed?

Only on the public pages, which run at least 15 minutes behind. Pro members, and anyone on a guest pass, 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. Where a company's SEC figures leave the Quality Score's sales, share count, or cash flow line empty, the score reads that figure from Massive's statements, and the Score tab says so. 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 to start. Tap any green button and you're in, free, 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.
