1/@PrimeMedicine’s recent #JPM26 presentation emphasised its strategic priorities & the company’s planned milestones for 2026-7. Here’s my🧵👇which focuses on PRIME’s new prioritised pipeline, the progress $PRME has made during 2025 & its current corporate status. $XBI #JPM2026 Prime Medicine’s recent JPM26 presentation emphasised its strategic priorities & the company’s planned milestones for 2026-7. Here’s my post which focuses on PRIME’s new prioritised pipeline, the progress Prime has made during 2025 and its current corporate status.
2/@PrimeMedicine’s proprietary platform - Prime Editing is the only Gene Editing platform which can edit, correct, insert or even delete large DNA sequences in any target tissue. This makes it the most advanced & promising editing technology with $PRME owing its full IP rights.

3/IMO the most important key takeaway from @primemedicine’s #JPM26 presentation is that in 2026 $PRME intends to submit INDs and to initiate clinical trails for both of its key programs - PM577 for Wilson’s disease and PM647 for AATD. Moving forward with its liver franchise and providing positive human clinical data are a threshold for $PRME to enter into a significant collaboration with a big Pharma company.Image

1/🚨WOW! According to this excellent Economist’s article 🧵👇 it seems that the 🇬🇧 big Pharma company AstraZeneca - one of Europe’s and England’s last remaining BioTech and Pharma moguls, is moving its business away from England! $AZN leaving the UK is a huge negative milestone in the deterioration process of both the British and the European BioTech ecosystems which are rapidly collapsing and losing ground to the American BioTech ecosystem - following President Trump’s Most-Favored-Nation (MFN) policy as well as to the Chinese one which has made an exponential progress. $XBIWOW!

2/The British government has always considered its life science industry as one of the Crown Jewels of its economy and rightfully so - a 145 billion dollars industry which employs over 300,000 high skilled employees is crucial for the British economy. The importance of the Pharma and Biotech industry has led the British government to a present a new governmental initiative to support the industry and that was introduced by the Labor government just 3 months ago.The British government has always considered its life science industry as one of the Crown Jewels of its economy and rightfully so - a 145 billion dollars industry which employs over 300,000 high skilled employees is crucial for the British economy.

2/In February of 2022 the U.S. Patent & Trademark Office has issued a crucial decision in favour of the Broad Institute, which validated its patents for CRISPR/Cas9 Gene Editing in human cells. This provided $EDIT with strong IP rights & gave it a huge commercial advantage. $XBI In February of 2022 the U.S. Patent and Trademark Office has issued a crucial decision in favour of the Broad Institute, which validated its patents for CRISPR/Cas9 Gene Editing in human cells.

1/This great @WSJ’s 📊 shows how after spending tens of billions of dollars for a single BioTech company, big Pharma moguls such as $ABBV, $AZN, $BMY, $AMGN, $PFE & $VRTX have all shifted to acquiring smaller targets of >$5B - for both regulatory & financials reasons. $XBI 🧵👇 After shelling out tens of billions of dollars for single biotech companies, pharma- ceutical giants such as AbbVie, AstraZeneca and Merck have shifted to smaller targets cost- ing $5 billion or less. Many of the companies getting taken out are private. The reason, according to ex- ecutives, bankers and lawyers: Smaller deals are just easier to do in the current regulatory environment, and the sector is looking pretty picked over.
2/All 17 deals made by big Pharma during the first 6 months of ‘24 were $5B or less. During the same period last year, big Pharma made 9 deals, including 2 that were $10B or more. 9 of the 17 deals were for privately held companies, compared to 1 during the same period in 2023. All 17 deals announced by big pharmaceutical companies during the first six months of the year were valued at 5 billion dollars or less, according to re- search firm DealForma. During the same period last year, big drugmakers agreed to nine deals, including two that were 10 billion dollars or larger. Nine of the 17 deals were for privately held companies, compared with one during the same period last year, DealForma said.
3/Last year’s big acquisitions were led by @pfizer’s $43B purchase of cancer biotech $SGEN ❤️👇. By contrast & to demonstrate how things have changed, the biggest deal so far in 2024 was @VertexPharma $4.9B purchase of Alpine Immune Sciences & its experimental kidney drug. $PFE
