GCEA shows us how to value a medicine not in terms of what you’d pay for the stock but what society should be willing to pay for the product itself. In this article, we perform GCEA for Cidara’s CD388, an anti-flu drug candidate.

When Capstan Therapeutics agreed to be acquired by AbbVie for a record-breaking price of $2.1B upfront, it had just started its Phase 1 study in healthy volunteers, was well-capitalized, and was on a mission to put a range of autoimmune diseases into deep remission and maybe even cure them. Some people will wonder about the significance of this deal and what lessons it may have for their own ventures. We can share our insights. We’ve been on the Capstan journey since the beginning and are incredibly proud of the team and its work. This is a story worth hearing.

Is AI coming for my job? It’s not uncommon to wonder these days. 

What if AI could just read a press release and appreciate the value of a stock at least as well as I think I can? Might not be a big jump from there to AI opening up its own biotech fund. 

But before I ceded my job to ChatGPT, I figured I would at least take it for a test drive by having it analyze a press release from a company I knew well.

Stylus, a Raven company that emerged from stealth this week with funding from RA Capital and others, is positioned to overcome the existing limitations of genetic medicines with its suite of engineered recombinases that are designed to recognize a safe harbor site in the human genome and introduce a therapeutic payload with high specificity and integrity.

Today, AbbVie announced it is acquiring Aliada for $1.4 billion, motivated by the potential for ALIA-1758, Aliada’s lead program, to be the best-in-class for the treatment of Alzheimer’s disease, and by the potential of the BBB-crossing platform to enhance its discovery and development efforts for other difficult-to-treat neurological diseases. As we congratulate the Aliada team, we wanted to share a bit more of the story behind the second significant acquisition from our Raven incubator this year and the first full-circle acquisition of a company we built with technology spun out from a larger company.

This is the first acquisition of a fully-baked, “home-grown” company from RA Capital’s RAVen incubator, which builds companies that our venture team funds and helps govern, so we wanted to mark the occasion by sharing a bit more about how we got here. 

There is a real and urgent need for better flu prophylaxis and therapeutics. RA Managing Director Laura Tadvalkar writes about why RA is excited to lead a transformative transaction that returns a long-acting antiviral for flu to its original developer Cidara, and RA’s new initiative to help make outlicensing from pharma companies faster and more efficient.

The technological renaissance in covalent inhibitor technology over the past decade is impressive. Relatively recent advances in structure-based drug design have unlocked the tantalizing opportunity to engineer covalency into small molecules. Now, RA Capital has incubated and seeded Hyku Biosciences to unlock histidines, tyrosines, and lysines for covalent modification to greatly expand the druggable proteome.

Clinical trials can fail, regulators change their minds, manufacturing might run into an unsolvable glitch, and venture capital might dry up. Given all the risks small biotech companies face that are outside of their immediate control, might it be safer to just work for a more stable, revenue-generating company? Maybe! But before you rule out jumping into a small biotech, consider the pros and cons.

Some might consider Trikafta’s gains to be “good enough” for CF patients. But I think we can do better. And that’s why we’re so excited to introduce the world to Sionna.
