See a lot of press releases from tiny biotechs touting their assets future eligibility for a priority review voucher. Almost all still quote >$100M as market value for a PRV. Are they not tracking the PRV market, surely mentioning >$200M is more attractive.

Attended a talk about carbon credits today, a lot of parallels weirdly with the priority review voucher program. - without financial incentive, companies wouldn’t address the need - the concept has led to new companies forming to capitalize - traded between companies and available supply dictates price - smaller companies create and large ones buy for commercial benefit

Did a review of licensing agreements to see how PRVs are valued in the market. Almost all use the average of the last three public PRV sales as the market value. I was expecting something more robust than this.

Was lovely to meet some of you over the last week in DC and NY. Back in a few weeks to BOS and NY. Think I’ll need to make a FAQ for my website, first question being ‘Why does this British guy care about PRVs’ 😂

The Priority for Pediatric Cures Act, seeks to permanently authorize the rare pediatric disease priority review voucher program. A very simple, one issue Bill, without any contentious add-ons. Hoping this means that it will go through Congress and the Senate without delay.

"Score every dollar on three questions before you sign. What does it cost in ownership? How fast does it close? What did you give up permanently? Grants cost time. Royalties cost future economics. Licenses cost territory. Equity costs the company itself. Raise in that order. Start eighteen months early. And answer the board’s question about which program to fund before the market answers it for you." Enjoyed this article from David H. Crean, CBO of MediciNova. (I have no affiliation with the author, company or publication, I just like the article) Edit: formatting oncozine.com/financing-the-l…

I missed this. $MRK Merck in Q2 earnings on Aug 4 said they'll use the Commissioner's National Priority Voucher for the FDA filing of sac-TMT in endometrial cancer. The voucher was awarded for triple-negative breast cancer, unclear if they'll get expedited review for this too.

Of the 22 Commissioner's National Priority Vouchers that have been issued, 11 have led to approvals so far. The quickest approval being only 23 days after the full application was submitted. Interested to see if the new FDA administration will continue to issue new vouchers.
