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

Next step the company has named

Q1 2027“The company is targeting an IND submission in Q1 2027 and first-in-human dosing in Australia no later than April 2027.”Filing with regulators · SEC filing · Aug 6

What it means: a filing asks regulators to approve a drug for sale. Once it is complete and accepted, the FDA sets a decision date, and we show it here.

For Pro members: 31 filings.

Cash runway

The company says its cash lasts into 2029 (8-K, Oct 5).

That is the company's 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 12, 2026)
  • At-the-market share sales program (424B5, filed May 7, 2026)

For Pro members: 4 raises and their amounts, and the share count against a year ago.

Insiders

An officer, Grace Wong-Sarad, sold 9,446 shares on Sep 4. 12 more insider trades this year.
