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
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.
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.
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👇
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
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.
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
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👇
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.
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
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
1/@nvelop_tx has presented its proprietary delivery system - DLVR-M, which has successfully demonstrated improved delivery of CRISPR, base editing & prime editing platforms to different human cell types. DLVR-M could be the key in overcoming the obstacle of CRISPR delivery. $XBI
2/Every Gene Therapy is combined from 2 components - the genetic payload which is the mechanism for fixing the genetic disease or the cure itself & a delivery vehicle which needs to deliver the “package” to a specific human tissue & location. Just Imagine a pickup truck & a box.
3/As of today the only approved delivery platform for Gene Therapy / Gene Editing is AAV - Adeno-Associated Virus based delivery. AAV is a naturally occurring virus being transformed into a delivery mechanism by replacing its viral DNA with new DNA thus making it a precisely coded vector & it is no longer considered a virus, as most of its viral components have been replaced
1/WOW! hC Bioscience announces its first ever tRNA-based program for Duchenne muscular dystrophy (DMD). hC is developing anticodon engineered tRNAs as a potential treatment for DMD patients with shortened & nonfunctional dystrophin due to premature termination codons (PTCs). $XBI
2/Duchenne is a severe progressive disease which rapidly worsening children’s muscle function often using a wheelchair by early adolescence & eventually needing artificial ventilation to breathe. DMD is caused by mutations to dystrophin that affect about 300,000 males worldwide & PTCs account for approximately 26% of cases.
3/A nonsense mutation or premature termination codons (PTCs) is an alteration in the genetic code that prematurely halts the synthesis of an essential protein. The resulting disorder is determined by which protein cannot be expressed in its entirety and is no longer functional, such as dystrophin in Duchenne
1/As promised and after reading $CRBU latest Q1 2024 financial report here is my impression regarding @CaribouBio latest corporate status. As always - I have focused only on the main issues that I found to be the most interesting & relevant. Here’s my summary 🧵👇 $XBI #BioTech
2/IMO the most significant corporate event was $CRBU decision - due to internal portfolio prioritisation - to terminate the development of its CB-020 program - a preclinical allogeneic anti-POR1 CAR-NK cell therapy - a decision which narrowed dramatically the company’s pipeline.
3/Another major event was $CRBU announcement that it had received FDA clearance of its Investigational New Drug - IND application to evaluate CB-010 ability to treat patients with lupus nephritis (LN) & extrarenal lupus (ERL) Thus expending CB-010’s therapeutic potential. $XBI
1/@LineageCell presented promising data at the @FightBlindness Gene Therapy innovation summit - as part of #ARVO2024, from its clinical study of RG6501 (OpRegen) - a retinal pigment epithelial Cell therapy aimed to treat age-related macular degeneration dry AMD. $LCTX $RHHBY $XBI
2/@LineageCell has developed a unique technology that enables it to transplant specific cell types from a single pluripotent cell line thus creating “off the shelf” cell transplants platform for multiple conditions. $LCTX most advanced program is its OpRegen ocular platform. $XBI
3/Dry AMD leads to the loss of retina cells thus creating an area of geographic atrophy-GA, which leads to impaired vision & blindness. By using a subretinal injection of RPE cells into the eye OpRegen will be able to preserve or improve a patient’s vision
1/@WaveLifeSci today announced the approval of its first clinical trial application (CTA) for its RestorAATion-2 clinical trial of $WVE-006, Wave’s first-in-class RNA editing oligonucleotide, which is being developed for the treatment of alpha-1 antitrypsin deficiency-AATD. $XBI
2/WVE-006 is a first-in-class, GalNAc-conjugated RNA editing oligonucleotide aimed to correct the single base mutation in messenger RNA (mRNA) coded by the SERPINA1 Z allele, thereby enabling restoration and circulation of functional, wild-type alpha-1 antitrypsin (M-AAT) protein
3/RestorAATion-2 is a Phase 1b/2a open label study designed to evaluate the safety & tolerability of WVE-006 in individuals with AATD who have the homozygous Pi*ZZ mutation. $WVE remains on track to deliver proof-of-mechanism data - restoration of M-AAT protein in serum, in 2024.
1/@VerveTx announced that due to observed laboratory abnormalities associated with $VERV-101, it has decided to pause enrollment in its Heart-1 clinical trial. Verve is conducting an investigation & will work with regulatory authorities to define a path forward for VERVE-101 $XBI
2/VERVE-101 is being evaluated in the Heart-1 Phase 1b clinical trial with trial endpoints of safety and tolerability as well as changes in blood PCSK9 protein and low-density lipoprotein cholesterol (LDL-C) levels in patients living with heterozygous familial hypercholesterolemia (HeFH), established atherosclerotic cardiovascular disease (ASCVD), and uncontrolled hypercholesterolemia
3/6 participants have been dosed at 0.45 mg/kg of VERVE-101 from a total of 13 participants. For the first 5 in the 0.45 mg/kg cohort (with follow-up of >28 days) $VERV-101 demonstrated time-averaged LDL-C reductions ranging from 21% to 73%, & averaging 46% (cut-off date 3/18/24)
