Mehdi Goudarzi

Thanks this our Mehdi Hi, Goudarzi question. for is Joon. taking for

related to great study, FOCUS-CX provide expected you this CXorfXX your the be would level treatment this if color could efficiency is specifically and of some question for and Thank it disease unchanged on Our possibility of considering you. pathology? of haploinsufficiency

Paul Bolno

to take targeting the we're how to I'll through to Mike refer go your the happy against We're question. disease approaching study. and clinical Mike?

Mike Panzara

haploinsufficiency. the take I to mean, of targeting publication to consideration the our taking strategy did preserving on we're in we that I variants approach think avoid the that recently have while is that healthy shows a that the importance reducing just variants, mutant

and that down that the the our of anticipate CXorf think protein. with the targeting approach balance that have that we strategy that in it current and has considered -- normal it the toxins is preserving XXX our bringing I we So again driven -- while compound

Mehdi Goudarzi

right, All great.

question. I follow-up a may I if have So

variant a specific allele is module selected, or not? WVE-XXX this also Your is

Mike Panzara

not go the after contain because all right is expansion in have was variants silence And of Well, goal entire the multiple where the have not that to right, variants that the way little it's case allele. to we the you different is The shown so gene expansion. the is get a actually the the presentation all -- transcripts the transcription here HD, are the in occurs way as produced. these goal the

getting So selectivity you're transcription. the also of normal targeting allowing you're mutant, but

the objective variant the in detail. this we good the because very a published on selective, actually -- in So in all bit different it than CX in objective through it that call essence goes paper it's we HD. it is In

the question the and for congrats thanks guys, progress. and morning, Good on

compare just on or guys And was point that in Mike ADAR potentially is your looking on there here as on or there XXXX? differentiation here, are field field any So the wondering CX Shape's a you questions and that the in you. data terms then Thank ADAR to if CXorf. I the release one language ask are develops? wanted as for I things triggers just can develops XXXX publicly of or ADAR you're as for couple we and get Korro's of data to to things wondering what Paul you program one the through clinical I'm here anything if just so could On program, the

Paul Bolno

CX. with ADAR we Mike and about before start over who pass I'll talk then Okay. can to

an stayed I very think that chemistry capability. that so at just the upon to it is ADAR nice focused last in-house our off short chemically and beginning leveraging of we time which capability progress, to your building that oligonucleotides the Day question cells chemistry gain of at see that it's this on continue best on R&D the I leverage believe made. it the in access early unique It’s we modified adaptations is something building to shared building right. we've and

and So getting endogenous potency it. using potency PN using the in ADAR the to both seeing so the to advantage enzyme on

do And to into to sustain that's ADAR. engage that accessibility getting lastly of Two, to ability the we've about I set that to over get oligonucleotides the so these the been cell work endogenous time. and short out critical. that's speaking So to And compartment activity durability. then think the

think great the more a it's space. people entering I editing as of ADAR endogenous to see field

to as optimize. and think to today, call alluded is what continue we've I Paloma the consistently on done

of on editing And the is the clinical what functional ultimately, that continuing to our that therapeutically protein production. that frequency patients. of candidate and is continuing the over which relevant that will protein we build functionality floor now reducing sustaining durability on measure the for and pharmacology today establishing where time have meaning, think alpha-X growing into antitrypsin go we So the and potency administration, subcutaneous approach so then, to

So have their in to think designs build I different others approaches taken the terms that they're and using toolbox chemistries. their of oligonucleotide

test as the make because we forward one the rodent answer accelerated models question chemistry to Does manufacturability, one, not potentially -- make of making at also we'll we'll is the think just our I capability of scalability talk what's the that is think to drivers to in that this I about chemistry take of here -- to take then, pause answered the advantage we of about this the molecules being able a ultimately but that we Wave that and Salim and question. preclinical on CX work know have can sure, commercializable ADAR primates therapeutic. key nonhuman

Salim Syed

helpful. Yeah, I Thanks that think was Paul.

Paul Bolno

Sure.

Mike Panzara

Great.

So on then dosing process ongoing imagine have here follow-up to the evaluation an independent recruitment committee safety can where the you you the of mean, CX, dosing, frequency. adaptive I and recommendations, is study design -- as flow

again, other study the material could the would to throughout those are that treatment, timeframe. benefiting, the of process some development including is mean, disclosure. be out nature continuous next could durations design. there or on going are feedback. to disclosing illustrated changes in phase This study the it's patients feedback would is are of of suggest material it's there and So that things make prompt positive of being that a sort committee would in us negative be a There's ongoing, I that moving a variety But block concept design, data to disclosures, things generated -- disclose. like study, aspects those that come it's that this regulatory of prompt is that assessments registrational changes of

Paul Bolno

not it's just CX Salim. unique And to,

forward data clinical thought clinical of that. programs. is in on we've think point, that much programs designs we've And data this generate and over decisions make the as brought been interpreting that I to I could I our why that in quickly -- we moving purposefully bring -- So generating Mike's we think innovative on multitude and our time about have to think to as terms molecules of then

now got forward as through XXXX. move think ample we've And or we opportunity I so

Salim Syed

the for time time Is looking you in you before the even planning are that there for how disclose to first that you're to that I Cohort data I there cohorts. cohorts data at? X mean, consider specific given single-ascending? releasing point is two or mean, a wait first are amount of four for to would you a certain cohort for the example, going pass

Paul Bolno

enrolled. studies think it I So --

you opportunities There's where across studies. trial I on the on saw being design. target that's As made assessments mean engagement ample are

studies the of cohorts. into that's built So across design the

studies. of clinical sampling to is each that not those a in that's dots I of think on what update one the we're regularly the scheduled guiding

that did study. that us of the the think are an I material study would out Mike say update in pointing to disclose occur a cause job great changes to would on we that there need

expand to again opportunities cohort engaging And you're example substantially you for to where that so there's the potency committee see knockdown target existing next the data and don't reviewing cohort. just forward-looking we move we see have the in as safety

set publicly, there would changes that data from be by the informed are study where design a the trial is deviation be we've what this out done. So as that can clinical to

exciting that card evaluate we're kind drive looked happy think end historically and at it's where of the the of we're So of I a as a end and see not of and updates. its periods now running And in landmark let where at And we studies. flip lot the fixed our cohorts five the given going data events past the those experience all CNS time in the I same where are. to think position enroll then that data

what know for substantially a to an study I that study. what to part provides this changing can assessments it enables to and the -- it provide is a Mike lead registrational challenging to could do, that these So that And that, periodic take important to would times us us is decision get of said as that contract is that. this

studies. the those as updates, to others provide we'll making progress and this as year So progresses -- we're the as along

Salim Syed

Thank very much. you Understand.

Paul. Hi. This Thanks Alex on taking for is for my questions.

have of wondering knockdown you disease of understanding question for, natural that. follow-up. sort And there or thinking from on PolyGP I another threshold are have looking how is you're we history, that a another links was an severity? about quick Thanks. relate how do to CX, And I Just then,

Mike Panzara

Sure.

is Regarding -- Mike. this

level of PolyGP right? may that not out the CSF. that data linked directly the is to be disease in the of suggests PolyGP, there The severity actual now of level the Regarding

just of there trying DPRs PolyGP treatment the CSF other different. are tissue So the affect may be also indicator. CSF are that which through are is also, we levels concentrations one an indicator to just of And

So clinical It its to would a it target it That's goal engagement efficacy again, is it's drive marker. confirm and into us purpose. down. get study. The would forward a

Alex Thompson

That Okay. the makes it's filing? on program, can at but steps and us for it sort And optimization sounds of just sense. see that AAT the walk of kind ADAR you point, this IND like, you an through

Paul Bolno

different. steps think of I not the mean, a lot forward are I Yeah.

approach what's or IND-enabling there's there bunch I safety safety think would in terms studies of think I take Salim of And studies. as different of important can So whole the enabling a mentioned the away do CT you and kind normal that I approaches.

as impacting anticipate oligonucleotide. think different that's there would another the be approach RNA we for bring would GalNAc therapeutic oligonucleotide we forward an I wouldn't that doing transcript, studies we be to

approach vectors impacting So using is this DNA. than different or viral the biologics

of model So levels that piece optimization, first engagement IMP that put aside, to this that that we're we've year, the point relevant is I on demonstrate that's Prior package. to first we think was that of step which half achieved standard your what to in toxicology at us a threshold. the this preclinical program that in in delivered target the tells

the we on is and call as potency, into that the on call as and Where alluded see that range pushing is durability. of about Paloma so optimization that the floor. higher to now with enhancement continuing mentioned balancing to occurring efficiency So editing us

administration. So of frequency again, the reducing

to update as data line that the a I a we're on candidate. think release since that in we're that much track to with on made compelling space the for program and that's it more we've clinical progress and will building give our doing excited advancing up comprehensive path why

So more at the what where kind of letting about durability on talked are potency to with We we've the without level that's come ADAR, optimization. think [Indiscernible]. it's fine-tuning now maximum about they Research to but Day achieve

finalization what the levels are package. of will So we're I think go just the substantial achieving we where today. into candidate It's

know are also thinking Biogen about think the SODX, not get the because I XX for you're is So data levels? NG can we have always they lung that and expecting this we but you. that fall. And and issues? some here ask going are that a Thank that question in for And believed data for aren't SODX-ALS serum AXAT Ionis do report wondering you know in after bar as just I potentially could NG and AXAT that but to know any liver patients, normal patients how talked programs. to KOLs on the also follow-up or have asymptomatic success is implications still the a at from your I to micromolar least achieving know the patients we back you And XX bar reason micromolar is we've originally and for

Paul Bolno

No, it's and one a second your then we'll take great question. I'll first transition.

micromolar talking that regimen. continued we about reason while I why we we're So the -- don't about stay dosing think talk a focused and we in why there's don't XX optimization on

we your us exactly could the AAT restoration So get point. key functional of levels, certain to for and achieve identification I think threshold was

we've was bring us forward key continue that the advantages that where opened I think floor door and the saying that establishing to of for are. possible

time following well. key over I to this as think is going be the

are sustaining functional not can where protein when restoring and at the your the we what's time. that a It's data opinion the with it's body it. pushing there had we've So about explained expressed is just as sharing needs leaders. where the that do requisite that's needs it. work It and a do discussions be going thesis over a protein we're and to needs the with the reactive And in level period to key it really underlying point, about body of Paloma

importantly, an a modifier. being side. not there's on this lot equivalent DNA we're approach restoration enthusiasm of and think seeing the approach I And this of functional one about for a excitement

that assay and protein, we transcribed the and functional protein meaning again, and are it's there making needed. it's that's So elastase this when

able of I -- being to of as floor really again blocks going think are push do And building pieces the excited show those into availability program. to So we're this the the more. the

it's As features. we've to we historically looked this pick at But of the other think transition do Mike let side. comparison to the number a in on and up I'll I important SODX and

I designs, it differences new in is exciting terms that exposure. new bringing we're chemistries distribution think have of forward that durability

So read-through challenging our somebody it's else's programs to and and from what own. compare under always chemistry

I'll and let support letting Mike we data think to I those data data drive vivo this for forward. have SODX think in we speak with those now our that letting preclinical we're our But extensive space. about programs programs how specifically

Mike Panzara

FTD, you that gauging And this the for with but it in clinical about when CX and approach leads outcome and I measuring still obviously track. we that benefit. meaningful of now great now disease once on for pharmacology, again approach No, PN the is effect -- that target potency a optimistic result for target patients like. have the think and about we've but upon intrathecal then clinically administration about this engagement Yeah. the the our high And depend is in potential this when that into a about demonstrating clinics. with different the advantages reduction look of what for to the quite we're validates to us and of where obviously effect approach a talking diseases think pull the disease two doing certainly -- data in makes actually right that in the into all next-generation target engagement in also potential neurological But translating it target you it been that will translating durable

it makes we for So it it to effect, potential are. clinical CX program administration IT brings to the us where leading at actually as looking optimistic pretty

Paul Bolno

that. on think I put in I mean, the end and a to Yeah. just summary

seen neurologic for is disease I in desire to we've think what the devastating work. medicines

while So SODX but -- an I ALS discussions do CX in smaller is there are open it underserved regulatory to variant overlap, on paths up I and around than patients. approaches that sense bring a the hope not we it continues that patients are and hopeful think there's think that for to

So best this space. I think -- we wish the everyone for in
