Jonathan Chang

the on Congrats all progress.

ESMO First the for how data you data of will how mature question, can terms much of in arginase help and ahead be? the program expectations the us at presentation

Keith Orford

be Yes, to a study combination well variety as XXX just and data the study. of cohorts. studying so is XXX pembrolizumab And you XXXX across the presenting the will as monotherapy from remind

as monotherapy data, the cohorts. presenting monotherapy cohorts will be -- well some combination of as we the So

Just study as the to reminder, enroll. continues a

will on part data of on a this maturity based cohorts the in data. present subset so of And we the

Jonathan Chang

Got it.

ENTRATA us terms historical you the of everolimus? patient for on can help And positive population update, we in contextualize the question, disclosed how thinking about Second should in data the the be study? benchmarks recent

Keith Orford

Right.

this yes, very pro is pretreated prognosis a population. So heavily

prior that these were were X published. patients towards kinase were have They therapies. just weighted inhibitor tyrosine previously heavily so categories in intermediate relative of and And and to been these most -- diagnostic received data general, core pretreated had

more suggested Prior everolimus. second-line the, population the say, first for heavily I would for new was have pretreated. populations. set this line, in X.X something the of of this months patients And in So data again, was range the this data everolimus receiving would PFS in later the

when -- our surprise that result the approximately a demographics. investigators two the so PFS reviewed actually not of And so to was we months

going to the In prior population. and let PFS on fact, it's demographics this having blind likely know reviewed we they a actual short then, the us be data for that to

Jonathan Chang

the Got we it. to when see And presentation can expect a ENTRATA of data?

Susan Molineaux

policy. in So is a practice of to submit our then the and embargo -- meeting exceptions to to disclose line medical data with meeting

have in when year So next of months more of plan know. quarter either or the year. we to we more coming you But information, first this we disclose will let data,

Jonathan Chang

it. post question. runway last Got on recent cash And Any offering? X just the guidance

Stephanie Wong

at guidance. you updated cash million. And But time, ended know, of we haven't $XX as $XXX.X expect that We to $XX million we the million. at utilize year to

back January. was guidance million been The and that that in June. in didn't include we raised that $XX the So updated hasn't just

well each the our we CANTATA these of capitalized I to programs, to milestones However, say meet including in are trial. can X continue

Operator

Our next question Bansal from Mohit the of Citigroup. coming with line

Mohit Bansal

study. on about my Congrats And related you're contrast And all CANTATA? to you remind which side study. progress ENTRATA arm the What from of in control how the ask following patient versus If CANTATA again then question we population, ENTRATA should I you can us the the the compare there? are from well. as just the X expecting may in enrolling

Keith Orford

missed. question, the I So second think I

Mohit Bansal

Its powering are CANTATA are powering versus study, how for how related of arm assuming What study? control treatment the arm? you the are you control And you to assuming there?

Keith Orford

Okay. Great. Yes.

So yes.

they So significantly the between populations CANTATA less RCC the these pretreated X patients, cell study. but And are that's are -- above similar. studies clear RCC in patient

primarily CANTATA So I'm approved, currently really where is sorry, is setting. cabozantinib -- where we're the focused the second-line which on in

patients or X required these X therapies. are have prior received So to

They X second the frontline have is they -- third or in I/O TKIs. will line. they a ipilimumab/nivolumab combination had previously received, I there or see X prior So if received TKIs, could or have X received

and most -- least, patients at of prior in X pretreated I/O but have patients these terms TKIs. TKIs. these expect to to many prior of We less would prior -- X of heavily received So

METEOR to control study, in the of And the cabozantinib In was PFS terms range the months. arm, the METEOR is X.X population of this similar a in study. the

some off patients have subset Again, have straight better be patients coming historical data. might of will -- somewhat And than are ipi/nivo. There some expect do we differences. in those should of to

we hand, forth. categories of so other terms are the other prognostic of what in On also that and play there the distribution factors -- are

hard to we're longer, METEOR not in probably it's we're be substantially. maybe the seeing than But study, So longer what slightly predict. somewhat but expecting will

Mohit Bansal

the action. one mechanism should be Did responses do setting the kind from Got ESMO, may more pronounced data, And if with more. I monotherapy it. agent? expect ask you Or of this will arginase we coming responses at the in combination think of

Keith Orford

Yes.

this new that PD-X. active I/O been has feeling Our -- developed are an being as I/O this more most therapy, would to as therapies be agent likely be with in combination

development really so our that's our plan. And terms primary in focus of

So we'll on think proof-of-concept that's where that I But inhibition the for has that about of question. And and nice -- really were if say, we molecule would to focus. more responses, talk I it support able you But would to at arginase activity. be that are see I nice its think own would But the ESMO. I responses be

Operator

with And Blair. William coming of from question line the our Phipps Matt next

Matthew Phipps

Since placeholder? data much little there they how a Jusy program. there, Is coming be is of the results the arginase towards kind obviously of the first, coming will in September, it's of believe, itself? I before in on conference more that are One actual the end a abstract?

Susan Molineaux

think somewhat to months. the focuses see is and what the and will the talking that ESMO. on fluid be of of it's of the is And we abstract I so trial, focus a to and ongoing think for course, we'll update that indicative there we be the abstract's couple get an of it be will most as data about similar closer an presentation. depends I focus upon But

Matthew Phipps

you on the overall to that. where presentation lined think data results? know ago. bring so lots full to know will do yet I But top the and the results, you weren't at you are guys of when months couple will they it out ENTRATA look trying figure So have depending still I survival guys matured

Keith Orford

again, they're Yes it mature. -- we'll when data OS -- present we'll present the

whether impact that presented, will presentations it's presentation. be the of possible timing the will so certainly in OS data not And OS data may but or be that

Matthew Phipps

populations, in Obviously, lastly, just the space palbociclib recent in this given thoughts then with results activity I get AMG XXX mutation. the now kind these on specific KRAS one may that's be KRAS-gene your And it. combo of of inhibitors. particularly only Got and to want some the

angle can that kind that's about thinking maybe you're but how So landscape, curious of guess. you take, an just I

Keith Orford

Yes. of that site particularly Obviously, the the to -- unique a been are has aspect KRAS them data makes impressive, mutation. susceptible. a And is restricted is but they there specific binding it

And whether to or it's question. open think other be as so inhibition, mutations not an KRAS will I susceptible

it's frequently And population. we're target cancer, need. confident So the as one genes at unmet an that continue you in most to and in know, interested of we remains remain important still omni and the mutated KRAS

Matthew Phipps

Do you combo some next studies think we from from initial year? the Pfizer X data see data

Keith Orford

study So by cohorts. open-label the followed be going design the to is of dose escalation open-label expansion

it's the but is would think know the study. now this to end I data present, . it's So right can not year, have But might randomized early we that some that we possible blinded of by a obviously

So it's possible would able the be next of that year. end to by we do that

Matthew Phipps

And I you you think back for trial to see Especially Or with last randomized additional year? the next of for Do Where wise ENTRATA telaglenastat, year, expansion the trials right the see data. plus two question. kind looking strategy results. combinations. Obviously, with additional want the combinations? broad results, CANTATA also now? indications happy this to this on ongoing results positive the true of positive novel do

Susan Molineaux

Matt. That's a question, good

addition, involved that's an that, quite current care are interesting saying start retrospectively that and ASCO, looking Intrusive of in to therapies, data poorly continuing back taking at of synthesis, PD-X had highest trials nerve the X glutathione the on where other pathway population stress and lung continuing is presentation We have showing sensitive. the population in, glutaminase of us in that's to examine probably the managing interest oxidative possible to others cell look to trials, key at at and And this serves that's we chemotherapies. both pathway,

we're and in in trials considering and that the data, ways questions we possible -- aware are So address to of future.

Operator

Our line with Fargo. coming next Wells question the from Jim Birchenough of

Nicholas Abbott

for this on Nick afternoon. It's Jim

First trial did And that first do XXX. look expect start to the like? trial? be you would CF on question when What

Susan Molineaux

starting -- it's and -- first just this of question I'll When hear, design was little fibrosis was hard The the to the it. confirm is trial? trial a cystic

Nicholas Abbott

Yes, trial when trial think And trial? would you what yes, I like? -- when be you'll mean, does that to the look that is able start

Keith Orford

Right.

So mentioned, and as CFTR CF safety studies so all CF on And mutation therapy patients forth. currently their able running of status, we're healthy the enroll and PK evaluating backgrounds. studies we patients, their irrespective and in will include be volunteers mutation so we'll current Patient of modulators. irrespective across to patients,

an So include renal population biomarkers be evaluation dose sort of evaluation will broad, and safety of as endpoints both escalation as of that business like and well of . your we'll

Nicholas Abbott

that guess of year? can I is next first early you next something half year start you think or

Keith Orford

Yes.

reasonable I a assumption. think, that's

Nicholas Abbott

And on XXX, Okay. that... inhibitors CDXX then obviously
