2020 Biotech IPOs – Large Molecule R&D Companies

Browsing through the pipelines of recent biotech IPOs is great way to catch up on emerging targets, novel drug modalities, and science at the edge of development. Unlike conferences and publications which tend to be a lagging indicator of what’s going on in industry (with many publications only being released years after a program has ceased clinical development), emerging companies disclose a lot of interesting data while they’re trying to raise funds for the very next step in development. Investor presentations, regulatory filings (e.g. S-1s), patents and posters contain a lot of insight that usually doesn’t make its way into a publication.

Below is a compilation of large molecule-focused R&D companies that were publicly listed via the IPO route in 2020 along with their lead molecules and mechanisms. One company’s already been acquired, and others have already received their first FDA drug approvals. It’s hard to cover newly public companies comprehensively given the surge total listings as well as in alternative listing mechanisms (e.g. reverse mergers + SPACs), but hopefully this is still a helpful snapshot of science at the edge. A searchable table appears at the bottom. You can download the full PDF here or by clicking on the image below.
