What Is SELLAS Life Sciences Group's Investment Narrative?

To own SELLAS Life Sciences Group here, you need to believe that GPS in the Phase 3 REGAL trial can eventually convert into an approved AML maintenance therapy and that SLS009 can evolve into a second meaningful asset, supporting a transition from a US$0 revenue, loss-making biotech into a commercial company. The latest REGAL update, confirming 72 of the 80 required overall survival events, mainly affects timing: it pushes the final readout into an open-ended window rather than changing the thesis itself. With the share price already up very sharply over the past year and the stock trading at a rich price to book multiple, the near term story now tilts even more toward binary trial outcomes, ongoing cash burn, and potential future dilution as the biggest risks, while the key catalyst remains the eventual REGAL data readout.

However, one specific funding risk here is easy to overlook and investors should be aware of it. The analysis detailed in our SELLAS Life Sciences Group valuation report hints at an inflated share price compared to its estimated value.
