you. Thank


you. Thank

Young Cantor next Our from with Fitzgerald. question Alethia comes

Emily Bodnar

discuss that ASH and taking Emily Are Alethia. about previously hypertension, for wondering our the there was the of patient? updates one-off a related that on you Thank was then for you're was still next I said patient as you. you possibly Hi. at had study it of towards development This And any kind to that questions. is case plan on drug. kind Thanks maybe case? do a rest your possibly data? you the that believe Phase of getting And could I of

William Rice

right. All

address I'll So – those. thank you, Emily.

the So the XXX X had B-cell patient milligram that observed and is had trial we This bed a only we’ve they that, as patient feel the put we to been level. was though they on Grade drug, I completed at the on malignancy BID that think four dose hypertension, days.

time, is a that that quite finding. So remarkable at

that is new So data. what And something so of patient is raises this go to multiple lead back hypertension. done you the then been there had ibrutinib, onset cycles, take which can do your realized review of it cycles we prior antenna, your have on wrong? time, to When we've

even that actually already We drug, Upon drug. they Grade was day day patient four Two XXX. were ever already – drug. also know it what, they X They in our before they’re that that X. screening, before on on in and on this hypertension had and went Grade Grade our new do was, progressed onset, began new began had they they received ever weeks that X, Grade they two two hypertension morning, further they later, onset before developed that went onset. X days, The days our

So the new in hypertension. they already the aggressive onset had

that all in less in trial four-day on at because at that we three other the of all dose stage the levels exposure other six-fold the least went is that than truly not or taking The at the the drug factors plasma even exposure convinced and looked of trial. patient. at drug patients were levels in the time their this the at even point was they the back two We're we that

So system. they their had very little drug in

also events, correlation all hypotension, then those. found we any cases, all patients either of any reviewed of no with cardiovascular We drug of exposure hypertension,

trends was said, seen no truly we don't that such and our drug, time then. So it possibly to we but we all physicians since related at it's believe the in view, related, our that understand have

development And present. I’ll So Dr. then, the next ask moment, that. wants about he if that add to in milestones to I think Bejar, asked a we you

at We be for trial. on, data of the in plan So B-cell same all available data all will June. next provide dose and the be the AML again, at EHA the to on will trial again, data patients, levels, true all major the the release malignancy

XXX milligram level. to And that Dr. dose want will include add anything to that? did Bejar, so you the

Rafael Bejar

I look the at that hard if trial, all our would see there duration exposure the you other and other treatment. and seen hypertension. made altogether association point pressure And B-cell patients pre-existing us not in any with were the who instances to short malignancy that. the our the just And about looking AML study hypertension reiterate in both have come made like patients even we the in into change of any blood with a history of

comfortable as that So glad understand your we’re a is signal. it better. the to a recurrent one-off I'm very that this not described this safety took that And that that true analyze to is time you carefully question we in

William Rice

a he that's to sure back greater to the Everybody much gave the – But but we on any also ask I going Marango, the development make we time. time comments to wanted comfort. point. next the the trial We wanted that forward. good took just plans if I'll really know on take everyone and it, did get add Dr. patients immediately, clinicians understood regarding

Jotin Marango

thoughts Yes. I'll some echo Bill that you of Thank And question. the described Raf and Bill. mentioned for thank you, previously. the

the and enrollment all right test studies are really seen these now, they dose to Our you've broadly criteria. escalation, designed

are all We comers. taking

safety value that through efficacy that are try dose upon keep for a the to different we out types escalation, test So there of understand group and as testing it's because diverse that's of the are really types patients, try we the going to of to we going drug go forward. to the way only us different genotypes

us next that's how on following not a strategy us of that the data show So you. in now, cohorts right, group, to once II, going and the hints have really expansion be here. also we diverse Phase the of give but the something best that the to it's position value this mentioned will only the Thank past. from we're breadth we've is right And few

William Rice

to thing want one I to add just that.

you physicians deep not? everyone, patients, time. remind and are it relapsed/refractory a Is these related patients just it SAEs And that says, we step so on anytime for So what's often going and to make must to drug protocol. difficult as to our tease we these well, and all to to is DLT, back you it prior AEs that happens, It's drug-related, fidelity out. a expand. so must this then okay, for and have? refer to certain understand really that the and have protocol also If have it very maintain the the they that Is happened

We and level more dose of advantage abide by more get protocol and will we will patients that to that data. on then gain the take

I'll and you So that, leave it at question. Operator? I thank for the


Thank you.

some So I as putting about those you of other those not recently, will that that patients patients some drug that fail, mentioned name. and of excited we drugs our our on the investigators of just from have heard this they're experimental failed one

do we to is what need So continue to dose escalate.

but seen lymphoma also We we've will include patients. a in activity now follicular CLL,

so So within lymphoma many of there medications. diseases that types still new lymphoma and are need patients

activity population to we then in there, for that’s hopefully, then they And other in those and lymphomas. or show we continue once patients population drugs likely to that can look then So place in on CLL failing try the study, activity – plan fail have the and pursue patient broad BTK, this all lot other drug it of serve few drugs, a form hit they and of that need a lot takes new We we other population. drug wild-type a of again, mutant a but quite too. that pathways to pathways. can you inhibit can But believe BTK to and

we lymphoma escalate with that but to parallel will come it and be CLL, So that's for on and why population slow need in dose the also focus then will patients. continue along, CLL to they the

if and like change stops, don't you it's you the cry, you driving, sit lanes and one So traffic and lane down and move start there whine on.

in we lymphoma CLL so Bejar, best And get to that? too. continue on will the we we'll lane as move lanes other and Dr. there can, to any the with the try into and addition the patients

Rafael Bejar

this the earlier of what that with breadth our drug. goals of said study the to one really echo understand Jotin activity of I’d and is

to to moment. You ourselves any don't this limit at one want indication

where to move escalation we with opportunity the comers all to quickly take to we and expand. will address more can point can as we get dose that So

William Rice

Much more succinctly Thank and you. eloquently said.

Matthew Cross

you you and know Great. kind you me navigating on trial, these to kind are traffic for going going helping squeezing thanks forward let one. another both it. of me thank letting be Appreciate how for guys And to of

William Rice

All right. Thanks.


Thank you.

from question next JonesTrading. comes with Soumit Roy Our

Soumit Roy

on the to Congratulations mechanistic where wishes validating It's to Greg fruition with I worries least or you also to some to bring concern. third-line you the and plastic the feel of can rather can everyone. Are good patient, a another enroll you in add time my you than lux. wait what's not this a at building, you turning coming hypothesis endeavors. Do or And recovery? translating to targeting can clinical into this to would your – until what's earlier range will kind be on you Hi, that's – deep able most, best venetoclax with range his the of have this it a line data, see because you you your with into is think little future that [indiscernible] what is hematological is very big marrow? see a question comfortable One Is have marrow waiting strategy Or patients broad concern combine lines? such late you for agent? you – investigators activity. is

William Rice

All right.

question. the for thanks Soumit,

a talk I'll Bejar Dr. second over this ways So about I'll of to question the to there. in answer it couple then turn

see never a what to duration, AML length hope CR. get you activity. So bring multiple we and patients, that significant about what future with Again, these drug hope the want AML, is to milestone. real talked patients. a to you We assistance can But to this hit pathways about the provide of to the is you're That in do them in AML. certain going

avenues. single-agent can get these are we as as demonstrate then additional the try patients much so possible to there to to if And activity, CRs, benefit get clearly

to get able be not to You them a transplant.

forward. combination You might the this going for – you up and trials then sets also

you In benefit. exact patient. of to would malignancy expect So the be timeline AML into a patients, longer would don't an see get B-cell I the requiring duration that to in want you

and that your Bejar can turn he can to back I to questions. perhaps over Dr. So add

Rafael Bejar


hope which But – the just to accurate different study. it So think mentioned, in you be nothing responses. then that's see really for will will I AML good that to it than we B-cell add, patients, certainly

advantage I parallel. think studies doing of have we in these the

So we in different contexts. the also learn of activity drug, we safety learn about not can only about but the can it

or on function, about have there. sense normal so that. including able to I'd by say haven't concerning but signals So that we otherwise specifically being may any a relatively who a And marrow and lymphoma test patients myelosuppression of get seen asked you have concerns, we

myelosuppressive the potential is to have would they and to then CG-XXX. in not the of that lines earlier of into induction same we interests AML course, if approved able to demonstrate come chemotherapy a for being likely have, those think different that about with unfit has But that overly to patient The that to given get don't question I populations move great not much So being safe frontline. inhibitor do regimen options a And that. benefit. we That exhaust therapy. point. Obviously, need diversity an very for the like everyone to all your receiving older the available of them. therapies first, And so without the they're example, FLTX it, patients are contains being

So whether not, they approved is or in do on nothing study there for setting. really that that them

a AML bring to to opportunity an luxeptinib think direction moving be drug is that might closer the I ease that But like that combination. So frontline. in

think other I to it'll to so that your be do So likely in with correct agents. have combination assumption is there

William Rice

would we that dose And toward… before went identify we Yes.

Soumit Roy

Thank you again. congratulations and so much, Okay.

William Rice

Thank you.


McCarthy one Thank question Maxim we with question Group. for more time have from Jason – you. And

Unidentified Analyst

for Hey, everyone. It's Dave Thanks on the Jason. my line taking for question.

action lends So as the mechanism the range of presentation, you mentioned to CG-XXX wide itself of indications. of on a

in that the I any mind, currently near you're if malignancies was at with other in looking wondering pursue So to just hematologic future?

William Rice

yes we are. So

then understand both in the to preclinical those base clinically. then first is hard begin which kinases hit that is explore do impacted So those science. by by are what it and on diseases, what We we try are and to this we pathways molecule. to identify One, targets then try and

We're yes, to well beginning single is helps tolerated. are think how continue. it's will expand. do and now that And see we the doing agent that see great that we us activity this being molecule really in we So clinic to still

single-agent have I to you drug part can talked stage. now start them. seeing earlier we all plans, – to you begin is confidence it's So the so now you're activity, of And next how – move we that's these what is about – you seeing that us implement that always giving now have to

long-winded does to Bejar Dr. But to of that? a add anything bit little want a that's So path.

Rafael Bejar

genotypes think different have in different sensitivity I is to may other that the malignancy myeloid the consideration drug. a only universe

that dose consider to first. the perhaps appropriate and need be them. explore greatest It's doing I other a might with area as the the exploring So more thing get we're sensitivity, that think we time and we're higher levels, right greatest to to indications by able AML

Unidentified Analyst

for color. Great. Guys, the thanks additional
