Modality
No religious view on modality. The question is whether the program is the right shape for the biology, not whether it fits a preferred chemistry.
- Small molecules
- Biologics
- Gene / cell therapy
INVESTMENT
The legacy criteria, written so a founder can read them in five minutes and tell whether to send the deck.
INVESTMENT SECTORS
Four sectors from the legacy investment criteria, kept as-is. The first three account for most of the check writing; the fourth is opportunistic.
Small molecules, biologics, and protein-degrader programs working on targets that pharma has not solved yet. Anavo, Halda, Magnet Biomedicine all entered here.
RIPTAC, RNA, induced proximity, AI-led chemistry, undruggable-target screening. We back the platform when the first program coming off it is something we would have funded on its own.
Programs Taiho Pharmaceutical has stewarded inside its R&D walls and is ready to externalize, alone or with a co-founder. Less common than the other three; usually the highest-conviction.
Adjacent areas we look at when the company is paired tightly to a therapeutic program — companion diagnostics for an oncology asset, a digital tool for adherence in a urology indication.
INVESTMENT CRITERIA
The short version of how we make decisions, by therapeutic area. The long version is on the criteria page, with the diligence questions we actually ask.
| Therapeutic area | Entry stage | Initial check | Geography | Board involvement | Detail link |
|---|---|---|---|---|---|
| Oncology | Research to pre-IND | $3M–$15M | US, EU, Japan | Voting seat or observer | Detail |
| Immunology | Pre-IND to phase I | $5M–$20M | US, EU, Japan | Voting seat | Detail |
| Urology | Pre-IND to proof-of-concept | $3M–$12M | US, EU | Voting seat or observer | Detail |
| Adjacent platforms | Seed to series B | $2M–$10M | Global | Observer | Detail |
MODALITY & STAGE
No religious view on modality. The question is whether the program is the right shape for the biology, not whether it fits a preferred chemistry.
Most of the portfolio came in at research to pre-IND. A few we picked up at IND or proof-of-concept when the science was right.
WHAT WE ASK
A short list of the questions that come up in the first hour. None of them are gotchas. They are the questions a chemist or a regulatory lead at Taiho would ask anyway; we ask them before the term sheet so the conversation after is about the science.
Q01
What does first-in-class mean for your target?
Specifically: what has the field tried, what worked, what was the failure mode, and what about your approach makes the failure mode not apply.
Q02
Which animal model would change your mind?
A working hypothesis becomes a program when there is an experiment that could falsify it. We want to know which one you would run if you had the budget.
Q03
Where does the molecule fail in PK / PD?
Every chemistry has a failure mode. We are more comfortable with founders who can name theirs than ones who say there is not one yet.
Q04
Who is the first patient, in the first study, on the first day?
A specific patient at a specific site with specific inclusion criteria. The answer is rarely on the first slide; it is usually on the slide we ask for.
Q05
What is the FDA conversation you are most worried about?
Pre-IND, IND, end-of-phase II. The conversation Taiho has walked through with regulators on commercial products. We are happy to walk it again with you.
