1/As promised & after reading $CRSP latest Q4 2022 #financial #report here is my impression regarding @CRISPRTX latest corporate status. I have focused only on the main issues that I found to be the most interesting & relevant. #CRISPR #BioTech #FinTwit #Genomics #GeneEditing 🧵 CRISPR Therapeutics, a biopharmaceutical company focused on
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 Regulatory submissions complete for exagamglogene autotemcel
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 3/Exa-cel - formally known as CTX001 and the key program in
4/Last December - during #ASH22 @CRISPRTX & $VRTX presented an updated clinical data from the exa-cel trail taken from 75 #patients: 44 TDT+31 #sicklecelldisease & with a long follow-up. The data demonstrates that exa-cel has the potential to be a one-time functional #cure.
5/Exa-cel was submitted to the @US_FDA for BLA rolling review with expected completion of the submission package by the end of Q1 2023. If approved - Exa-cel will be the first ever #CRISPR product to be commercialised & marketed thus making @CRISPRTX the first to sell a product. Exa-cel was submitted to the _FDA for BLA rolling review wit
6/@CRISPRTX second program is CTX110 - a wholly owned donor-derived #GeneEditing #allogeneic antigen receptor T cell #CAR-T #therapy targeting CD19+ B-cell malignancies. CTX110 has also been granted a Regenerative Medicine Advanced Therapy - #RMAT designation from the @US_FDA. CRISPR therapeutics second program is CTX110 - a wholly owne
7/Patients that were treated with CTX110 as part of the @CRISPRTX #CARBON #clinicaltrail have shown good results. CTX110 was well tolerated across all dose levels & patients in CR remain clinically well without receiving any systematic anti-#Cancer #Therapy other than CTX110👇 Patients that were treated with CTX110 as part of the CRISPR
8/@CRISPRTX has recently provided a clinical update for both its Part A & Part B of $CRSP ongoing Phase 1 #CARBON trial evaluating the safety and efficacy of CTX110 its wholly-owned #allogeneic CAR T #celltherapy targeting CD19+ B-#cell malignancies. Here is a 🧵 that I wrote👇
9/@CRISPRTX will initiate clinical trials for CTX112 - next gen CAR T platforms targeting CD19+ B-cell malignancies, in 1H 2023. CTX112 incorporates the edits in CTX110 plus additional edits to the genes encoding Regnase-1 & TGFBRII, thus increasing the potency of the CAR T cells CRISPR Therapeutics will initiate clinical trials for CTX112
10/CTX130 is another $CRSP wholly-owned #allogeneic CAR-T #CellTherapy targeting #CD70, for the treatment of Mycosis Fungoides & #Sézary Syndrome - both types of cutaneous T-cell #lymphoma. In September @CRISPRTX announced that the @US_FDA has granted it RMAT designation. CTX130TM is a wholly-owned allogeneic CAR T cell therapy tar
11/CTX130 has showed overall a good safety profile - patients that were treated with CTX130 as part of the @CRISPRTX #COBALT #clinicaltrail have shown good results with #disease control rate DCR of 90% (N=10), 70% ORR & 30% CR rate. $CRSP CTX130 recent readout was also promising
12/Two interesting collaboration that @CRISPRTX’s has entered recently are: 1)@MoffittNews for developing new #autologous CAT-T #CellTherapy targeting CD83 for treating #AML. 2)@RoswellPark for developing new autologous CAT-T #therapy targeting GPC3 against solid #tumors. #Cancer
13/@ViaCyte & $CRSP have 3 #CRISPR #GeneEditing programs - VCTX210 in which the first patient was dosed as part of a Phase 1 clinical trial. $CRSP expects to move the other two In-Vivo programs - VCTX211 & VCTX212 - both for #diabetes into the clinic in the next 18-24 months👇 Following the previously-announced clearance of the Clinical
14/@CRISPRTX has named recently another 2 new #CardioVascular programs 1)CTX310 for #ANGPTL3 & 2)CTX330 for PCSK9. Regarding both - IMO $VERV is much more advanced & especially after @VerveTx’s recent data & the ongoing #Heart-1 trail it is most likely to dominate this market. CRISPR Therapeutics continues to advance a number of program
15/As of 12/31/22 $CRSP had capital resources of $2.24B & R&D expenses of $103M. IMO @CRISPRTX’s current cash position will enable it to continue to develop its clinical pipeline with hopefully the first #CRISPR commercial product hitting the markets in 2023 & generating revenue Cash Position: Cash, cash equivalents and marketable securit
16/With an highly anticipated first ever @US_FDA approval for a #GeneEditing platform expected in 2023 @CRISPRTX will be the 1ST #CRISPR company with a product in the market & with a strong cash position of $2.24B - @CRISPRTX IMO continues to look very solid & promising. $CRSP With an highly anticipated first ever FDA approval for a Gen
And as always please do feel free to #share & #retweet so that those on #Twitter / #FinTwit who are interested in #GeneEditing, #CRISPR, #BioTech & #Genomics will get this relevant data. Wishing you all a great #Week!

1/🚨WOW! $CRBU has presented updated clinical data from @CaribouBio ongoing CB-011 CaMMouflage phase 1 clinical trial in cancer patients with relapsed or refractory multiple myeloma (r/r MM). The CB-011 CaMMouflage phase 1 translational and clinical data - which was presented at the 2026 Tandem Meetings of ASTCT and CIBMTR, demonstrated deep and durable responses and further support the potential of CB-011 as the best-in-class allogeneic CAR-T Cell Therapy for second-line relapsed or refractory multiple myeloma patients. $XBI 🧵👇WOW! $CRBU has presented updated clinical data from its ongoing CB-011 CaMMouflage phase 1 clinical trial in cancer patients with relapsed or refractory multiple myeloma (r/r MM).

2/Multiple myeloma is a type of blood cancer that develops in the patient’s bone marrow when plasma cells become cancerous and produce abnormal proteins instead of functional antibodies. Common symptoms include persistent bone pain (often back or ribs), fatigue, frequent infections, kidney damage and high calcium levels. While modern treatments (chemotherapy, targeted therapy, stem cell transplants) can manage the disease for years - Multiple myeloma is still considered incurable and present a significant unmet medical need.Multiple myeloma is a type of blood cancer that develops in the patient’s bone marrow when plasma cells become cancerous and produce abnormal proteins instead of functional antibodies.

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!
