Management’s own date

Into H1 2028

Jan–Jun 2028

Guidance counts money received after quarter end, so it is not converted into a burn rate.

“We expect that our existing cash, cash equivalents and marketable debt securities, together with the net upfront proceeds from the public offering, will be sufficient to fund our operating expenses and capital expenditure requirements into the first half of 2028.”

Does the cash reach it?

Cash to the catalyst, barely

Runway
9.4 months
Time to the date
6 months

It is about 6 months out. At the current burn the cash lasts roughly 4 months past it. That is a thin margin: a slipped enrollment date or a delayed database lock turns a data-driven raise into a necessary one.

Interventional studies where this company is the lead sponsor, from ClinicalTrials.gov. Primary completion is when the last patient is measured on the primary endpoint, which is when the data exists rather than when it is announced. Extension, rollover and healthy-volunteer studies are listed but marked as non-catalysts, because they finish long after the result that mattered. Sponsors revise these dates as enrollment moves, so an estimate is a plan rather than a promise.

The controller’s read

What the filings say.

Generated from the numbers above using the same questions I ask when I open a client’s books: how long the cash lasts, what is driving the gap between loss and burn, and where the accounting judgment sits.

The cash reaches the next catalyst with little to spare

The next dated event is a phase 1 readout in Apr 2027, about 6 months out. That leaves roughly 4 months of cash on the other side. Enrollment slipping a quarter would erase it, which is why the cash forecast and the clinical timeline belong in the same model.

About 9.4 months of runway

Cash and investments of $55.6M at Q3 '26 against an average operating cash burn of $17.7M per quarter over the last four reported quarters runs out around June 2027. Under a year of runway is where ASC 205-40 going-concern evaluations, financing timing, and cost plans all get decided at once.

Cash position down $71.4M since Q4 '24

Net financing inflows of $49.2M over the last four quarters, from equity, debt, or ATM sales, partly offset operating burn. The balance is the number the board watches; the trend is the number the auditors watch.

Net loss runs $3.7M above cash burn

The Q3 '26 net loss of $20.0M includes non-cash charges, including $1.3M of stock-based compensation, that do not consume cash. Burn, not net loss, is what runway is built on.

R&D is 81% of operating expenses

$16.6M of R&D against $20.5M of total operating expenses in Q3 '26, with G&A at $4.0M. For a clinical-stage company, the accounting questions live inside that R&D line: CRO and CMC accruals, milestone recognition, and what gets capitalized versus expensed under ASC 730.

Going-concern language in the 10-Q filed Aug 13, 2026

The filing contains definite substantial-doubt language, the conclusion of an ASC 205-40 evaluation that cash may not cover twelve months from the issuance date without additional financing or cost actions. Read the liquidity note in the filing for management's plans and whether they are considered probable.

Accumulated deficit of $512M

Total losses since inception. It is also roughly the size of the net operating loss carryforward the tax provision has to track, subject to Section 382 limits after each ownership change.
