1/@GraphiteBio announced that after reviewing its business, it decided to discontinue any further development of nulabeglogene autogedtemcel (nula-cel) for #SickleCell disease, to explore a range of strategic alternatives & to reduce 50% in its workforce! #CRISPR#BioTech $GRPH
2/@GraphiteBio is also exploring the potential to continue nula-cel development externally. $GRPH intends to continue research activities associated with its early-stage non- genotoxic conditioning program, with the goal of advancing toward potential development candidates.👇
3/In addition, @GraphiteBio’s Board of Directors has approved a corporate restructuring that would reduce the company’s workforce by approximately 50%, among other actions to reduce cash burn while the company explores strategic alternatives. $GRPH
4/As of December 31, 2022, the company had a preliminary unaudited amount of approximately $283.5 million in cash, cash equivalents & investments in marketable securities.
5/Here’s my 🧵 about @GraphiteBio’s recent announcement about pausing its Phase 1/2 #CEDAR study of nula-cel for #Sicklecell disease #SCD due to a serious adverse event in the first patient dosed & $GRPH conclusion that this event was likely related to the study treatment.👇
2/IMO the most significant corporate event in Q4 was $CRSP announcement that regulatory Exa-cel submissions of both #SickleCell & #BetaThalassemia validated in the #EU & #UK & that the @US_FDA BLA submission is on track by the end of Q1 ‘23 - possibly reaching the #markets in ‘23
3/Exa-cel/CTX001 - the key program in $CRSP portfolio, is an #autologous Ex-Vivo #CRISPR/#Cas9#GeneEditing therapy aimed for patients suffering from #TDT or severe #SCD. The latest readout for both programs was phenomenal with 42/44 TDT & 31/31(!) demonstrated remarkable results
1/@LineageCell announced it entered an exclusive option & license agreement with $ERNA for the development of novel B2M deficient induced pluripotent #stem#cell#iPSC by using Eterna’s #GeneEditing technology thus developing therapies for #CNS diseases. #BioTech#CRISPR $LCTX
2/The new cell lines - to be developed by $ERNA, will support the creation of additional product candidates at $LCTX and specifically for the treatment of central #nervoussystem#CNS disorders & other #neurology targets via Eterna’s IP #CRISPR collaboration with @FactorBio
3/This agreement will also allow @LineageCell to enter the #CRISPR field and will provide $LCTX an option to obtain an exclusive license to utilize & sublicense $ERNA novel #GeneEditing cell lines for #preclinical, #clinical, & commercial purposes in the field of CNS diseases.
2/GPH101 (nula-cel) is a #CRISPR#Cas9#GeneEditing autologous #stem#cell-based #therapy in clinical development aimed to treat #SickleCellDisease. GPH101 is designed to directly correct the underlying mutation, thereby decreasing HbS production & restoring HbA expression #ASH22
3 $GRPH gene correction platform involves editing hematopoietic #stem cells found in the #bonemarrow that develop into various types of #blood#cells. Since red blood cells lose their genomic DNA during maturation-tracking #GeneEditing in mature cells via sequencing is impossible
1/As promised & after reading $NTLA latest Q1 2022 financial report here is my analysis regarding @intelliatx latest corporate status. I have focused only on the main issues that I found to be the most interesting & relevant. #CRISPR#GeneEditing#BioTech#FinTwit#Genomics👇
2/NTLA-2001 is the most advanced In-Vivo #CRISPR/#Cas9#GeneEditing program in $NTLA portfolio & is aimed to treat Transthyretin Amyloidosis - (ATTR). NTLA-2001 could potentially halt & reverse the disease in a “one time” treatment by knocking out the TTR gene with a single dose
3/In February $NTLA has presented an updated clinical data from its Phase 1 study of NTLA-2001 which included 15 patients with ATTR amyloidosis. IMO NTLA-2001 readout looks promising & here is a summary that I wrote shortly after @intelliatx’s presentation of NTLA-2001👇
