Operator

Truist is Securities. [Operator line question of Lee with first Instructions] Your the Joon from

Joon Lee

for couple questions questions. of a updates. thanks and and have the I guys, Hi, the

again approach approach being your For way antitrypsin would one, what better your explain of the Alnylam by a effect can or DMD and access chemistry, the the have backbone able and program, different you us overcome of number to from chemistry for you. taken is tissue program, patients editing you the ADAR for your Thank remind what program, knockdown than is percent chemistry? could Dicerna? in prior PN need the how therapeutic And to your you

Paul Bolno

and Thank divide Chandra in bring second. two Joon, parts; into we'll you, this I'll a

to about don't we been of liver. for As knocking within brining approach while the editing differentiation, excitement approach around discount relates silencing, silencing, on a lot out, the mutated correction ADAR, and protein as excited that and or there's we over an we're a the forward it down laid or

think alpha-X we of correction. of antitrypsin really it approached deficiency and from when we think area I the the approached

is, mutation we do to that restore point the the hepatic such that as both of So we of fix protein, liver physiologic it and balance complications the well enabling the this pulmonary lung. the as how treat

is a arm. down this driver drive key us the to for So correction

it heterozygosity about talk know we patients, patient As so a XX% if the that the is correction of restoration, manifest heterozygous, doesn't these a or do we disease.

by about to physiology. think Chandra, [anything but up to] with is -- between of there in you [ph] ADAR we So to means restoring want that correction XX%, anything add physiologic be you don't terms needs where no protein question? the the correction the to XXX% normal to

Chandra Vargeese

pretty you that think I much No, covered.

Joon Lee

just that… Hey, from Paul,

Paul Bolno

Yes.

Joon Lee

be, two manifesting clinically? ADAR question, the how as be will it you up finish you approaches expect editing, surely approach your works different and knockdown How both would as differently? approach envision clinically assuming by they the then to would Just expect these works

Paul Bolno

I initial treat as -- out terms we pulmonary the know to complications. replacement are protein in the of mean Yes, that therapies there's now

correction silencing. or interchangeability therapy augmentation kind as now there, protein as So and desire replacement of therapies of is a liver well that's so there is of augmentation about to with think the there this protein

we be therefore the protein wild-type really physiologic and as body the protein, the to normal so restoring both to stand for correcting think I use the in they work both, the and need lung restore letting liver. the balance, to able proteins

really protein the of So potentially they -- would replacement therapy. silencing require or necessity wouldn't

Joon Lee

and Yes, DMD… the

Paul Bolno

across a data question, I'll DMD, in Mike we but to and that today, cell the of about muscle, other on it day, for as you neurons of continue DMD, do but answer to we subsequently, we'll I PN on one the and generating the vivo there's aspects. let obviously, chemistry, we want Mike, shared can Yes, as the uptake think shared DMD? relates about and and research just across as this in lot as question excitement context we're talk mean of answer to transitioning see

Mike Panzara

Sure. yes. Paul, Sure,

as PS/PO we're just the in said, different durability when distribution, to So importantly identical tissue of mean I molecules. are added very PN access, Paul seeing backbones and something terms

a see address clear So the why difference effects, model, thinking what we in these that in first we're all, the but exon you this terms vivo in of XX, are, clinical versus tissue, terms in in we're model, of PN. issues, could PS/PO targets terms it a of DMD, seeing of where

different. clearly clearly that here durability effect to Paul I introduce a to which we're alluded introduce difference that molecule is said, seem, a backbone how the as tissues. The earlier, does overall there seeing negative potentially And as -- the So encouraging. on is changes PN charges accesses the neutral

address So maybe with could suvodirsen. concentrations change having this at we with tissues higher in better that it of saw, lack longer we access access saw this the

and it exon really that different targeting and study to into question, ASO of you is hope, with that seeing can an far there only take we efficiently as lot can here a need that that with so the give molecule answer the are picture overall to human preclinical a targeting or and described. are of that very take an characteristics data do us that you but in the a exon manual, So just we

Joon Lee

Thank you.

Paul Bolno

just other as important reduction also DKO that study that was mean one think, in and the -- yes, with to -- to that. the the I was dose. Yes, other follow-up the piece substantial comparison, Mike mouse Joon, think the I I on alluded of

improvement, but not every just drug, not that really and So that kilogram, PS/PO per less week, XX% seeing even seeing weekly. XX so milligrams so other improvement that at than

that I important. So as think see we

diaphragm. I is in phenotype with sensitive think also pulmonary see distribution we model distribution heart and good cardiac which and heavily that to across

questions excited characteristics point up there. is should noted a were augmentation, IV weekly One about therapy Alpha-X antitrypsin is bring pretty just be and it that you infusion. to the about back other we're So asking that protein to deficiency

off pretty something also physiologic in restore weekly the we're correcting, able that's IV patients of a just the to but being protein, of the terms forward. about real of move able normal of terms not excited in to to being in administration hepatic, So protein brining lung, correction just

of with from Your Foroohar the is question Mani line next SVB Leerink.

Rick Bienkowski

Hi, good progress. the morning. for on This Rick line My first is also NXXX. on is Mani. on Congrats the question all

preclinical more or little in So chemistry? access, to compared studies besides expect would guess the was seeing to tolerability in PN improvements you with window a And tissue the bit I any what either on you see therapeutic suvodirsen? can I you're hoping elaborate

Paul Bolno

to continue. amount We're as I'm going data at we're that the seeing often substantially a so purely let think I I about -- to mean, of with where have phenotype Mike around to talk really distribution talk -- the note, has times interval time is it's seeing a we phenotype, less a the those that drug changes that mouse in longer. expanding that's because -- MDx I and mean dystrophin. we isn't and I important people alluded, one, dose, out think there

said, I model being this with compound, about us skipping that's as the So does Mike model exciting chemistry. think phenotype exon this have XX the with what's is for PN corrected this

Mike Panzara

as preclinical to less other that that different. be given say seeing would effects quite supported are that lower clearly that the window therapeutic molecules. leading window, doses therapeutic of all by as we're we well studies the in suggest expect frequently difference to Yes, the and mean also between I there's a I

obviously difference, until you know, hypothesis we why So way that here but study to difference. determination on focusing target a of small there this a enough but with is in definitive us proceed number to engagement be that anticipate decided is best make you in the whether that there to information test which would we've patients, humans that a is can don't give being to proceed focused,

Rick Bienkowski

Thanks All you the and so into with maybe follow-up right, have from of for that escalation dose some you a discuss Huntington's I the that, PRECISION-HDX the it. brining you're program, HDX got of learnings about and be WVE-XXX? at or in dose the -- a more clinically start rapidly And and maybe than newer could to you'll more studies, escalate relevant think if able HDX escalation earlier at you the than you PRECISION-HDX a the study? could

Paul Bolno

take question? do Mike, to you want that

Mike Panzara

absolutely. sure, Yes,

think patients. to lot, community, X. from how I how to we've and studies, that how PRECISION-HDX So, We've these learned a to find engage run learned obviously,

here a is important I vivo bit where a as situation the on we be. thing earlier, where think help in to I guidance we have need we're in mentioned us is, give data more to

that's in driven the clinical dose how the ongoing starting study I more levels has So to be we comes out window expect we important in think pharmacology, an what's to a vitro, has vivo once in a would different is would next PRISM engage and dosing and where and this every we're at again, scenario to once approach different platform study. what's those that itself, as as characteristics well in that -- very data guide going vivo target, molecule the of a we going would that anticipate that escalation from therefore generating and the be fashion in by data

elements driven our also some So adapted that of see the you'll we've have when we the study have the -- you pharmacology pretty XXX studies, differences see you'll by from are that molecule. there meaningful and see existing been

Paul Bolno

now phasing, those of that just are. able ability patients understanding Rick, around practice patients where identifying we're with thing lot for the terms good also to with a we're SNPX is, and point, screening to add where with apparatus screening do other the the SNPX, the around SNPX and studies in -- have by think to ongoing SNP, now more the efficiently to patients of those to I having that SNPX your a and

So the as the SNPX itself, medicine beyond at this. place clinical look to the the is operations just program trial we for of SNPX characteristics infrastructure the do of totality in broader

Mike Panzara

Absolutely.

Rick Bienkowski

taking All right, questions. for great. Thanks our
