It is stories like this that shake me to the core when I see the profound scientific illiteracy that grips the USA and it’s current government!!! Measles Took My Daughter. This Is What I Want Everyone to Know. https://t.co/TLfcaBZHPX via @NYTOpinion

SCDAA is disappointed by the @nbcsnl skit about the recent historic approvals of potentially curative gene therapies for #SCD. SNL chose to cast a spotlight on this news with a tone-deaf skit that is distasteful at best and harmful at worst. Read more: https://t.co/D7t7R3h1Ki

@BillAckman @MIT Studied @MIT and @UCBerkeley, and saw a lot things I didn’t agree with, or left me scratching my head, None of these detracted from the learnings I took with me from these great institutions. There is enough self indulgent outrage in the world.

Working with the community makes us stronger and smarter as we advance EDO51 for people living with DMD, amenable to an exon 51 skipping Rx. EDO51 demonstrated 20-fold higher levels of exon 51 skipping when compared to published data with naked oligo Rx in humans.

[PepGen @PepGenTx]

PepGen is grateful for the insights shared by members of the DMD community at the recent Duchenne Community Advisory board held this past weekend in Amsterdam. For more info on Duchenne CAB https://t.co/ASJ6dkzBiL

@PepGenTx So proud of @PepGenTx quickly resolving the hold to enable US #DM1 patients to participate in Freedom-DM1 EDODM1 Rx for debilitating disease mytonic dystrophy type 1 #myotonic. Freedom1-DM1 is open in Canada and we look forward to bringing real change for people living with DM1.

[PepGen @PepGenTx]

We are pleased to announce that the FDA has cleared the Investigational New Drug Application (IND) to initiate the FREEDOM-DM1 Phase 1 study of PGN-EDODM1 in patients with myotonic dystrophy type 1 (DM1) in the U.S. https://t.co/WBIcne1k6h

PepGen Pioneers participated in #WalkToDefeatDuchenne to raise funds and awareness for #DuchenneMuscularDystrophy research. Our inspiration, @defeatduchenne founder John Davidson, first pushed his son Jesse, who lives with #Duchenne, across Ontario in his wheelchair in 1995.
