It was refreshing to have a CEO who can actually communicate which is such an improvement over the previous inept one. I'm pleased with the new emphasis on concentrating on the three main programs: LYT-100, Gallop, and Seaport, plus Cobenfy.
Starting with Cobenfy, I was a little surprised to discover that the patent only runs until 2033. I assume BMS must be confident about extending it. Nonetheless, even though it appears PRTC can only claim royalties up until 2033, it was a welcome addition to see the board's conservative sales forecasts and what that should translate to in terms of revenues for PureTech. I'm obviously hoping those forecasts are smashed, but penciling in around $300 million in revenues for PRTC up to 2033 is good to know from a modeling perspective. I don't actually have the presentation slides in front of me, but I'd need to check if that figure was discounted or not.
Moving on to Seaport, the Glyph platform is really very exciting. I'm not sure when the Phase 2b data is due to read out, but assuming this data is as good as we all hope, there's no doubt that Seaport will be worth multiple $billions as we move into the Phase 3 trial. This is even more evident given that I remember Daphne Zohar suggesting the Phase 2b may even be registrational. Nonetheless, it's very exciting, and it's good to have a number: as per the last funding round, PureTech's stake was $256 million. Considering the market cap of PRTC is currently $400 million, that values the rest of the business at $144 million—which is ludicrous when you consider i have not yet accounted for $320M of cash, LYT100, the cobenfy revenues and Gallop oncology.
The jewel of these probably being LYT100, which has shown significantly greater efficacy than the current standard of care and greater efficacy than any of the other drugs in clinical trials for IPF all of which are using new mechanisms of action. It's hard not to envisage LYT-100 gaining a significant slice of the multi-billion-dollar IPF market if the Phase 3 trial replicates the very thorough and well-put-together Phase 2 trial. When you couple this with the promising progress of the immunotherapy drug inside Gallop Oncology, which not only is showing great promise but also has both orphan drug and fast-track designation—a Phase 2 trial seems a given here based on the data at hand.
To top it all off, we have $320 million of cash sitting on the balance sheet, enough to see us through to 2028 and ensure we can participate in the subsequent rounds of all these founded entities. The share price is a joke, unless these all turn out to be duds, patient investors will be rewarded. Upwards and onwards.
