Xenon – P1 data provide more de-risking

To me, the main challenge in today’s biotech market is finding good quality assets with attractive valuations. There are definitely a lot of promising programs out there but valuations are often hard to justify as they reflect limited development risk and unrealistic commercial potential. From a risk/reward standpoint, it is hard to get excited about valuations of >$0.5B for companies before clinical proof of concept and $2-5B for clinically validated programs.

From that perspective, Xenon (XENE) is a market anomaly, with two promising clinical stage programs, a robust discovery platform and a market cap of just under $100M. Its two epilepsy programs, XEN1101 (Kv7 opener) and XEN901 (Nav1.6 inhibitor), are still in P1 but at the current levels the upside potential is too significant to ignore. Continue reading

After a long stagnation, is CNS starting to crack?

After being the industry’s graveyard for over 20 years, there is finally room for optimism in CNS (central nervous system) disorders. The void created in the field is now being filled by small companies which are using novel therapeutic (gene therapy, antisense, antibodies) and development (genetic validation in humans, biomarkers for patient selection) approaches. While clinical results are early and sparse they may represent the beginning of a new innovation cycle in CNS. Continue reading

Biotech portfolio update – Sage, Marinus and Immunogen

A new lucrative indication for Sage (and potentially Marinus)

Last week, Sage (SAGE) surprised the market by announcing preliminary but impressive results for SAGE-547 in patients with postpartum depression (PPD, also known as postnatal depression). Four patients with severe PPD experienced a dramatic improvement in their depression score from an average of 26.5 to 1.8. In other words, these patients entered the study with a severe debilitating depression and became symptom-free within 2-3 days. Despite the preliminary nature of the results, they generated a clear efficacy signal that merits evaluating SAGE-547 in a randomized trial, to be started later this year. Continue reading
