Diffusion is a clinical-stage biopharmaceutical company developing trans sodium crocetinate (TSC), intended to enhance oxygen diffusion to hypoxic tissues. It had no approved products or product sales. Its stated near-term priority was developing TSC as an adjunct to standard-of-care treatment for hypoxic solid tumors.
Financial performance and position
| Metric | 2021 | 2020 |
|---|---|---|
| Product revenue | None | None |
| Research and development expense | $8.5 million | $9.4 million |
| General and administrative expense | $7.4 million | $6.4 million |

Loss per share was $0.25 in 2021 versus $0.30 in 2020, with weighted-average shares rising to 97.6 million from 53.8 million. The company raised $31.1 million net in its February 2021 stock offering and received $2.2 million from warrant exercises. Total liabilities were $2.9 million; the filing reported no credit facilities or committed borrowing capacity. Operating margins are not meaningful because the company had no product revenue.
Material changes and unusual items
- Net loss increased year over year, primarily reflecting the $8.6 million non-cash impairment after the company abandoned further development of DFN-529. R&D spending declined 10%, while G&A expense increased 16%.
- Cash increased substantially following equity financing, alongside a significant increase in shares outstanding.
- The company terminated its former headquarters lease and moved to short-term coworking arrangements.
- The auditor issued an unqualified opinion on the financial statements and reported no critical audit matters. Management said disclosure controls and internal control over financial reporting were effective; the auditor did not attest to ICFR.
Outlook, commentary, and risks
Management said year-end cash was expected to fund operating and capital requirements through 2023, but anticipated further financing would be needed to complete TSC development. This is a forward-looking estimate, not a financing commitment. The company expects continued losses and no product revenue for the foreseeable future.
- The TCOM study showed a positive trend in peripheral oxygenation, but the reported effect was not statistically significant. The Altitude and ILD-DLCO trials faced enrollment delays related to COVID-19 and other operational factors. Management expected topline results within two months after study completion.
- A Phase 2 hypoxic solid-tumor trial was targeted for the second half of 2022, subject to FDA feedback and availability of clinical drug supply.
- Key risks include clinical or regulatory failure, dependence on third-party manufacturers and a sole API source, supply-chain constraints, further financing and shareholder dilution, and competition. The filing also disclosed Nasdaq’s bid-price deficiency notice, with a May 2, 2022 deadline to regain compliance, and a proposed reverse stock split.
- A former executive’s lawsuit remained pending; management said it could not predict the outcome or any loss range.
