Your line is open.

Greg Harrison

for With assess CNSA-XXX Hi, asset when to or see reduction the this for minimum taking as us the the color whether Thanks give you be additional of you some is how question. on data? And see this a criteria we Geoff. making our there there going the asset, level on important Greg Harrison could to the as decision? should is thinking is decision regards any acquire bar fee other to you're you in that

Eric Dube

Greg. Yeah, thank you,

then add you So I'll share ask else. I'll to with my and thoughts Bill anything Rote

want the we're primarily in asset. the need clinical meets is to we going And the current this way product that established We in sure would the that essentially, looking that profile of to the do market CNSA-XXX a at So be make there be we deliver believe that on need still to unmet a do unmet market. assets not. able

at we requirements because and by also market, going look be But this to the this going we we're non-clinical pathway at the evolve likely able market certainly is at time, that given particularly is speed it PKU be to be a that So entrants There competitive which to dynamic. currently are new to that regulatory in clinical will bring how would pre-clinical what we looking also what's want looking the think be it or we'll market. profile. over asset phase. are to are; the But

of we that be that over key we addressable for before what a a efficacy are data. decision. about So Bill Those months looking little talk next now, what sure invite and make the the at we make will fee market areas be. will the at looking bit to want And three the understand we'll I'll to we reduction be couple

William Rote

you view program. whole it's said, Certainly, the of a I as holistic mean,

that know hit. need for a we with fee reduction, care. to off I qualitative established we've cut standard which numerical specific the more don't a over existing it's superiority But think view Specifically, clear of I of

those they for to categories, a them you see point non-responders, those And a significantly who weak response. where Those into So be two difference. who are where really a are push patients would see or responders? we'd improved the for you can want become responders,

Greg Harrison

- Thank the dynamic overall know evolving? you and just it's fit of the but could Great. don't if follow about competitive in you'd acquire and you I pricing, decide just in market there, PALYNZIQ with Kuvan kind asset maybe about you. if you if thought to and I how have see up, And, early, how the

Eric Dube

I generic all certainly, Yeah, And Kuvan. will mean, into would trends into this is Greg. But Thanks, that certainly, play again, on we're need. to we want pricing. we that continuing input what for look those not make thoughts would new our think of - delivering be on well the potential look sure like those we've pricing. as at pricing including asset the And unmet we potential importantly, our entrants, thoughts are that on decision. what And as to disclosed an most our specifically primary

Greg Harrison

much. so Thanks Great.

Operator

Our next question Blair. comes of William Lugo from Tim

is line Your open.

Tim Lugo

for Thanks the question.

do have And of how the maybe base upcoming the have the was you age follow-up of how population or and you medications? For a open-label the many it enrolled, study? patients into could rolled FORT that ranges portion heterogeneous line speak to sense concomitant Study,

Eric Dube

detail Yeah. Tim. the progress been your we've And to question. so share invite pleased Hey, bit far. both I'll Certainly, Noah on of a more with

Noah Rosenberg

Tim. Hey,

the adults overall, say, as the We are mentioned we're can a the blinded the emphasize terms conduct. one-third a entered study, we, have we I portion in reminder, remain by completed question, to about information. your retention the that and have giving the amount led say seen to two-thirds of we've representative see just of really So the patients demographics, open-label we pediatric. previously of first open-label. and part And open-label pleased blind the specific only We we we're as It's limited study. would the portion of numbers. study the remain double far now majority encouraged population. We But well. as But in of with the

in it's And now making in but instance, XXs. baseline - well. are then, what families, rating finally, tell share in demographics, And that possible. we can't some just patients locked. want published to PKAN to results isn't course, this for And for the of median we final the the fair think of the database can considered I we saw and it's validation and as specifics, the participating similar terms say the consistent study, which to that you other until was PKAN-ADL upper the data the is PKAN-ADL I thank of

of So and like expect that's design. feel able hopefully an right there, be effective I to we've reflective our assumptions show to it And to We initial patients enrolled what fosmet question does answered your do. the Tim. we

Tim Lugo

definitely. can the what maybe Yeah, pool and UPDRS the PKAN And us and you the are between Part II III? differences specific remind

Eric Dube

the Scale. validation really done was II, of UPDRS essentially of living so the were which is that Rating Unified - There XX mentioned Parkinson's with Yeah, Noah Part activities the Disease part lot daily the patients are in are what versus community or symptoms their that those are to understand caregivers. disease. we with that And PKAN the to Parkinson's was that the of study work did hallmarked that specific a

that's that changed can couple the that those speak of the And were items approach one from intent. So Noah to the and taken was to other.

Noah Rosenberg

PKAN-ADL, the such on sitting - independently weren't in the there each. felt these item were Tim, of [ph], I freezing. these which overall, just They which two II. so, the I is a out look X want UPDRS any scale change they're be separate from chair. Part that the of that also or if a population. remember, that is There relevant getting items relevant point domains XX was were to when four way designed There was to essentially you at was tremor removed, mention think of [UKPDS] will was scale that were are and And one clinical are that terms effect. which a problem And point the designed, scales, domains. There adapted Yeah, added,

even recall keep effect. a changes modest as patients, it's changes. to you with So PKAN-ADL compassionate - significant clinically But in the I using important in double-digit the think II meaningful we signal mind. the Again, would that UKPDS saw use

Tim Lugo

around around if all you Could that in, more around are support? to Thank I retention, kind I comfort Great. could the interest of hearing sneak issue KOL And for talk is especially KOL the support, that it the what's be maybe support? be [WCN] and just mention that [ph], did and that that you interest [ph] Is action] if leading more - you it which [mechanism prior? holistically just class may comfort with one fluid was you of apologize. an may Or what's details. But

Eric Dube

things I think, there feeding into are that are a few that.

to and in the think that of in well got that on we're is, some I are number one DUET proven. earlier tolerated long-term product we the to continue to are - coming demonstrate little a that as we've data, that fact less the other see folks opposed

presented lot you there on So I studies [CRIDNS] two think if at large were emphasis that [ph]. that a specifically there safety. I that that more meeting is long-term that and think, recall, also there durability and SONAR outcome were

these Things in there's I nephropathy risk like together that there is were double risk, reduce diabetic disease. what looking drugs serum or these hard But syndrome studies than And actually and to population end-stage prove or taken renal that we're slightly studies. in nephropathy outcomes. think is at. for both and different nephrotic residual residual demonstrated outcome population improve potential this creatinine the

potentially down credibility for potential and mechanisms of well provide long-term as utilized then think on ERA, concept overall road different I'll even and more also the So credence in SONAR of combining those the that improving outcomes. adds it background the add nephroprotection, it which of both - compound, terms ACEs support finally, inhibition, to or rationale and for was was RAAS as in I just and you the ARBs the while data, of

Tim Lugo

hear. great the for Thanks detail. to It's all

of question Raycroft comes Jefferies. from next Maury Our

Your open. line is

Maury Raycroft

the good progress. everyone, on congrats afternoon and Hi,

First study. question is on DUPLEX for sparsentan X the Phase

Can how XXX to out best comment eGFR could way eGFR? play on FPRE, for on approval there. succeed try power Assuming you understand expectations slope weeks? for What's at that to the and your you differences accelerated

Eric Dube

Yes. Maury. Hey,

So to Noah, one. this you want take

William Rote

this Well, Bill. is

going I that, off care, of lose a the we expecting powered We're the that. population best or think each patients those that expectations in that that, even is are see to and five of eGFR at to treatment statistically to end mils delta absent of FSGS three standard significant of year.

haven't powering revealed helpful? you what specific what can that it. that give But around or of size is We the is. effect the generalities some that Is

Maury Raycroft

That's helpful. how that play XX-week, proteinuria relationship I guess point, And the I insight and get would eGFR some also we guess? at so between at about into or greater eGFR confident out

William Rote

is So at not weeks that there time show point, it's XX if difference. to clear enough the at

of the that in So in a two one endpoint The two and a weeks at diverse. years longer to lines leads those for to XX why longer then of for variability you the confirmatory effect looking reason primary have two size out study why build running the you and the combination you proteinuria at and eGFR. that years that's the point need it's review way we're study such at

Eric Dube

Bill. Thanks,

long-term renal really renal outcomes. or that that curves weeks show X.X remission survival partial have I as at partial a think I XX better endpoint which as proteinuria look really on that for whereby used reduction XX% complete was which the FSGS or of thing well It's at of is the other greater to below. on the done is in those baseline that endpoint based proteinuria level is that remission of composite endpoint, or proteinuria, a actually health, is would add modeling

But a function. which can you that think longer-term of believe based was renal basis or looking would DUET, could weeks. we I endpoint, large so predictive at then be XX for And a show on that be

Maury Raycroft

label then provide Thiola, as your quickly went maybe on I'm company for the any the the Got package it. just focus as shift if And opportunities, filing to second to to what that, pipeline on wondering, then current strategic with in color extensions more commercial the Thiola? helpful. - any in you question the the to thoughts Very more And can on NDA?

Eric Dube

Thank Yeah. you.

the new much of certainly about sure the formulation So want we've that next time disclosed the Thiola, that approval, is we - not make will month. at which of to share we

I was of we'll challenges serve you and the to with the from heard current very formulation much certainly can the more, that so And we patients tight on the tell share the but some what package formulation. that we

So month then. share eve next the date of and again, certainly we're PDUFA at the on the we'll end of more

further expansion, out products that for of cetera. of But in label continue management, evidence, that look more for point. something this do continue and something to decided not to any our to we that's et we that In at disclose develop have lifecycle how it's terms we

Your line is open.

Michelle Gilson

There Hi, you atrasentan, a thank elaborate data comments. of bit for just Congress maybe indications could IgA were versus a talk hoping guess, touch more selective question. World endothelin you presented taking about Nephrology was I I see my and FSGS on, nephropathy on is ideal you the from nephropathy which for this sparsentan and mechanism? you diabetic why A read-through to just antagonist. Could receptor any are more

Noah Rosenberg

here. Noah it's Michelle, Yeah,

population other then tends with to and atrasentanm, there population heart sicker higher little of I a think we're there rates failure complications. and nephropathy, this So of in are it's what seeing - be diabetic

those the with the to data was these cases confer carefully properties addition, for we've that in managed actually diuretics, no more patients. of diuretics outcomes. population. in So was treatment worse significantly some that compound, terms at fluid seen confidence managed that any but was context DUET A FSGS see compound us heart may of our heart look some the actually We you was of gives actually a favorable properties But With and lower in even lot failure it in in know, failures. signals heartening that the retention and that as in with of with even

for safety proceed. overall So solid gives data very to basis us us from standpoint I think a that a good

question next of Nomura. comes from Marai Our Christopher

line is Your open.

Christopher Marai

Thanks question. afternoon. the good taking for Hey,

us could remind the you should primarily the one. you UPDRS one there - the fosmet. this if or on onto a regarding patient then we And further PKAN-ADL. single mapped in versus two, maybe wondering, just if X elaborate is the Phase Just reports - was those could Number in are studies, you. in that in open-label or of PKAN-ADL to follow-up. that results drug? you'll on how other really components Thank have and And for that then that think one the number mapping case exploring one be on on I on included if the couple actually the changed dose the you individual

Eric Dube

All right.

would So you like to those questions. Bill, take

William Rote

Phase The Sure. a milligrams Study is three currently XXX times day. X

was I that up how XXX does times those from milligrams question think individuals XXX compassionate with to three setting day, in a use they per the day. range milligrams compared your

in we're at higher we as Phase those had X,XXX doses. X went Study, milligrams administration, In high in even as single ballpark. that and pretty tolerability So reasonable

The PKAN. mapping from PKAN-ADL. question the individuals other and occur saw, that scale only really effect bridge that freezing the to the UPDRS of in removed and compassionate over components aspect don't and measured were your draw and which with comparing in we patients trying The to was were use the tremors,

ability PKAN-ADL, change, So you the chair those assessed should you be independently can that's patients, when to get in one components a more it net sit unassisted. out is not a go which of you've neutral had to and

difference. be would that only domain was So the new and

UPDRS in depends patient the is So that's either patient scales, they is there one where PKAN-ADL than of The reported physicians reported, or on the one diverge. more reported matchup some and difference the settings. caregiver that's much

your So I question. you helps hope that with

Christopher Marai

bit we what that versus the that one I I PKAN-ADL, that's one more meaningful about? Absolutely. a just you any then And be expect Thanks. be, in effect file scale And the Thank not, regards thinking would were pediatrics more see just on, And suppose, you about thinking on treatment an might and the to then be adults, if NDA one expectation relevant you. to you other versus group should with to clinically population? other? the clinically suppose,

Eric Dube

I'll address. Yeah. just

rating. again first how X question domain the works PKAN-ADL again emphasize to and around X is the is So XX the points just X to whole powering scale

would a we changes meaningful. on Bill to. low-single-digit we double-digit while see did as that or placebo so PKAN be Again, the alluded would anticipate these improvement And scale

I be subpopulations. here, it's a changes, the we with significant you power would small is subpopulations, disease really and these regard but in question a values studies to So we is answer modest it patients, fairly those to as P show expect the rare see group to clinically think now, do aren't to

think, meaningful favorably. in I in again quite disease even point we're totality changes we of to the important these would how treatment it's and in there no modest And upon understand disease something really and every would data looked believe and pediatric that be approved a small population at and where is So look the patients. be improving data would be

Liisa Bayko

expect you about I period. XX-week a the to and know thanks of a my background Thanks. question. about want endpoint, Would much ask how about little natural just you when taking the Hi, looking over bit of for change? that Study at history, more kind FORT as sort or thought the

Eric Dube

that us is reduction hard of flares worsening, know stepwise, what's steady a We ton can study. this modest of do been we effect XX maximal say studied. we're don't our see - term. months sure have see with state. to just that while worsening a effect I'm - folks see are to talked well answer weeks, a think their We rare It's is there and power the we We sorry, disease. at to hasn't with that gauge of experts helped I'll able the weeks, And you that disease knowledge patients XX the not worsening don't about this at to that going based that's XX question. on that think a But in What maximal population. see of that or to clinically Yeah. we're meaningful best maybe referred are a occasionally so be disease we position it's episodic. to that typically stepwise to background heard effect. going

Liisa Bayko
