Cash at Q3 '26 divided by the average burn of the last four quarters, $5.1M a month.

Oct–Dec 2028
That implies $6.1M to $6.9M a month, 1.2–1.3× the recent pace.
In line with the last year“Based on our current business plans, we believe that our existing cash, cash equivalents and marketable securities as of September 30, 2026 will enable us to fund our development activities and other operations into the fourth quarter of 2028.”

Cash past the catalyst
- Runway
- 2.7 years
- Time to the date
- 7 months
It is about 7 months out. At the current burn there is roughly 26 months of cash left on the far side of it, which is enough room to raise on the result rather than ahead of it.

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 next dated event is a phase 1/2 readout in Jun 2027, about 7 months out. That leaves roughly 26 months of cash afterwards, which is the position you want: the raise can be negotiated on the data instead of on the calendar.
About 2.7 years of runway
Cash and investments of $166M at Q3 '26 against an average operating cash burn of $15.4M per quarter over the last four reported quarters runs out around May 2029. More than two years of runway means the finance conversation is about deployment, not survival.
Cash position up $130M since Q4 '24
No meaningful financing inflows over the last four quarters, so the change is essentially operating burn. The balance is the number the board watches; the trend is the number the auditors watch.
Net loss runs $7.4M above cash burn
The Q3 '26 net loss of $24.2M includes non-cash charges, including $2.1M of stock-based compensation, that do not consume cash. Burn, not net loss, is what runway is built on.
R&D is 80% of operating expenses
$20.7M of R&D against $25.8M of total operating expenses in Q3 '26, with G&A at $5.1M. 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.
Accumulated deficit of $335M
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.
