And I’ll now flip the decision over to your host, Mr. Conor Richardson, Vice President of Investor Relations at Shattuck Labs. Conor, please go forward.
Conor Richardson
Thanks, operator. Good afternoon, everybody and welcome to the Shattuck Labs convention name concerning our fourth quarter and full yr 2022 monetary outcomes and up to date enterprise updates. The press launch reporting our monetary outcomes was issued after market shut this afternoon and could be discovered on the Investor Relations part of our web site shattucklabs.com.
Throughout this afternoon’s name, the Shattuck management group will present a enterprise overview of the fourth quarter and full yr of 2022, together with scientific improvement updates for SL-172154, our lead program and SL-279252. We’ll refer to those as 154 and 252 all through in the present day’s earnings name.
Talking on in the present day’s name might be our Chief Government Officer and Scientific Co-Founder, Dr. Taylor Schreiber, who will evaluation our pipeline progress and upcoming key milestones, adopted by our Chief Medical Officer, Dr. Lini Pandite, who will present an replace on our ongoing scientific actions. After which our Chief Monetary Officer, Mr. Andrew Neill will evaluation our fourth quarter and full-year 2022 monetary outcomes and monetary steering. Dr. Schreiber will return to make some closing remarks and we are going to then open the decision for questions.

Any forward-looking statements symbolize our views as of in the present day, February 23, 2023.
With that, I’ll now flip the decision over to Dr. Schreiber, our Chief Government Officer. Taylor?
Taylor Schreiber
Thanks, Connor. Good afternoon everybody and thanks for becoming a member of us in the present day. 2022 was an operationally targeted yr for Shattuck and our scientific group did a wonderful job of advancing 154, our lead clinical-stage Agonist Redirected Checkpoint or ARC merchandise candidate. As a reminder, 154 is a SIRPa-Fc-CD40L ligand bi-functional fusion protein, which serves to each block the macrophage checkpoint molecule often known as CD47 and in addition prompts an essential immune stimulatory receptor often known as CD40.
Linking these two features inside a single therapeutic differentiates 154 from all different CD47 inhibitors in scientific improvement. We’re very happy to have accomplished the Section 1a monotherapy dose escalation scientific trial of 154 in sufferers with platinum resistant ovarian most cancers and achieved all the major targets of this primary in human research together with the choice of a dose of 154 to advance into our Section 1b mixture cohort, which I’ll describe in a second. From a pharmacodynamic perspective, we consider that the scientific information generated by means of the course of the Section 1a trial has validated one among our central hypotheses and the design of the ARC platform and proven that 154 was capable of safely activate CD40 in a dose-dependent method, together with doses which saturated the CD40 receptor.
One of many major pharmacodynamic results we noticed in-patients handled with 154 was a fast induction of interleukin 12, attaining excessive serum concentrations of IL-12 in plenty of different cytokines extensively believed to be essential to help anti-tumor immune responses. Quite a lot of different pharmacodynamic findings have been additionally noticed on this trial and we’re trying ahead to sharing these information at a medical assembly towards the center of this yr. Briefly, we’re very happy to have accomplished the targets of this research and to have choose the three mg/kg dose to maneuver into the mix cohorts. As a category, to be able to see clinically significant efficacy, CD47 inhibitors rely on mixture regimens with one other agent that gives a professional figures to sign reminiscent of a focused antibody or ADC or with an agent that causes immunogenic cell demise.
Because of this, we’re happy to have moved into the mix research, the place goal responses are anticipated in each our ovarian most cancers trial and our scientific trial for sufferers with acute myeloid leukemia and higher-risk myelodysplastic syndrome. There are two mixture cohorts ongoing in our Section 1b scientific trial in-patients with platinum-resistant ovarian most cancers. Within the first mixture cohort, 154 is being mixed with a chemotherapy agent often known as pegylated liposomal doxorubicin or PLD for brief. We chosen PLD together with 154 for a number of causes.
First, PLD causes immunogenic cell demise of ovarian most cancers cells and was proven to boost antitumor exercise when mixed with 154 in preclinical research. Second, PLD is a standard-of-care within the platinum-resistant setting and is well-known that sufferers handled with PLD have an goal response price within the vary of 10% to 12% from a number of Section 3 scientific trials. Thus, this was a mechanistically pushed mixture technique the place we don’t anticipate issue figuring out the contribution of 154 and the routine as a result of recognized low response charges of PLD as monotherapy. The second mixture cohort in ovarian most cancers is the results of collaboration between Shattuck and ImmunoGen. ImmunoGen acquired accelerated approval for an antibody-drug conjugate often known as mirvetuximab soravtansine, which targets an ovarian most cancers antigen known as totally receptor alpha or FR alpha for brief.
The preliminary approval of mirvetuximab is for a biomarker chosen subset of platinum-resistant ovarian most cancers sufferers, whose tumors categorical excessive ranges of FR alpha and the target response price is 31.7% for these sufferers. In preclinical research, we demonstrated that combining 154 with mirvetuximab, potentiated anti-tumor exercise not only for ovarian most cancers cells that categorical excessive ranges of FR alpha, but additionally for tumor cells that categorical medium and low ranges of FR alpha. Thus, it is a mechanistically pushed mixture the place the contribution of 154 is predicted to be noticed each by way of bettering total response charges and response length throughout the spectrum of FR alpha expression. If profitable, this might greater than double the proportion of sufferers who profit from mirvetuximab.
Whereas we’re excited concerning the alternative in ovarian most cancers for 154, we’re additionally happy to be properly underway in our scientific trial of 154 in-patients with AML and high-risk MDS. As many listeners might be conscious, AML and high-risk MDS are among the many indications the place CD47 blocking antibodies first demonstrated scientific exercise and have been the primary approvals based mostly on total survival could quickly happen. Over the second half of final yr, our scientific group initiated each the monotherapy dose escalation and azacitidine mixture dose-escalation cohorts and we stay on monitor for our scientific information milestones within the first half of this yr.
Though we acknowledge that the target response charges for the primary technology of CD47 inhibitors has contracted on this affected person inhabitants over the previous couple of years, we’re excited concerning the alternative that opens for brokers like 154, which offers the essential element of CD40 activation, along with CD47 blockade and which improved antitumor immunity in preclinical tumor fashions and printed head-to-head research compared to CD47 blocking antibodies.
Allow us to now flip to our SL-279252 program, a PD1-Fc-OX40L ligand bi-functional fusion protein. We now have accomplished the multicenter open-label scientific trial evaluating the protection, tolerability, pharmacokinetics, antitumor exercise and pharmacodynamics of 252 in sufferers with superior stable tumors and lymphoma. After enrolling PD1 inhibitor skilled sufferers to the 12 and 24 mg/kg cohorts, we didn’t observe an total response price of 20% or larger, which was our goal to justify additional scientific improvement. And thus, we’ve got made the choice to discontinue the SL-279252 program.
The scientific information generated from sufferers handled with SL-279252 counsel that OX40 stimulation within the setting was inadequate to beat the resistance mechanisms in-place in-patients who’ve already failed a PD1 inhibitor. I wish to take this chance to thank the sufferers and their households for taking part in our research. As all the time, we stay targeted on delivering novel therapeutics which is able to profit sufferers experiencing most cancers with excessive unmet medical want and look ahead to the mix information in our ongoing scientific trials with SL-172154 within the coming quarters.
With that, I’ll now flip the decision over to Dr. Pandite, our Chief Medical Officer, who will give you extra element on every of those research, the rising information illustrating how 154 is a differentiated CD47 inhibitor and also will give you steering to the varied scientific milestones which are coming over the course of 2023. Lini?
Lini Pandite
Thanks, Taylor and good afternoon. 2022 was a yr of excessive operational focus and I’m happy with the execution of our scientific packages and the continued progress we’ve got made. Our scientific focus is on the development of 154, our differentiated CD47 inhibitor and CD40 agonist with scientific information coming to see us on every of three completely different scientific research. As Taylor talked about, we’ve got now accomplished our multi-center, open-label, dose-escalation Section 1a scientific trial supposed to evaluate the protection, tolerability, pharmacokinetics, anti-tumor exercise and pharmacodynamic results of intravenous administration of 154 as monotherapy in-patients with platinum-resistant ovarian most cancers. As a reminder on this trial, we reached a most administered dose of 10 mg per kilogram and we didn’t attain a most tolerated dose. As you’ll recall from the final quarter, we didn’t see any proof of misery deepening which we attribute to the design of the Fc portion of 154 and the absence of binding to Fc gamma receptors.
We anticipate to report the complete information from this dose-escalation portion scientific trial mid-2023. Following the completion of Section 1a dose escalation scientific trial and deciding on a dose, we superior to enrolling sufferers in our Section 1b scientific trial of 154 together with liposomal doxorubicin in sufferers with platinum-resistant ovarian most cancers. This multi-center, open-label trial is meant to judge the protection, tolerability, pharmacokinetics antitumor exercise and pharmacodynamics of 154 together with liposomal doxorubicin.
We anticipate to report preliminary mixture information from this trial mid-2023. I’m additionally very excited to share particulars about our new collaboration with ImmunoGen. We now have initiated enrollment in a Section 1b trial to judge the protection, efficacy and pharmacokinetic of SL-172154 together with mirvetuximab soravtansine in sufferers with platinum-resistant ovarian most cancers. As Taylor talked about, we consider that 172154 could broaden the exercise of mirvetuximab past simply folate receptor alpha excessive expresses and thus we intend to enroll sufferers throughout a broader vary of folate receptor alpha expression, together with these with excessive folate receptor alpha expression outlined as 75% or larger media folate receptor alpha expression, outlined as lower than 75%, however larger than or equal to 50% and low folate receptor alpha expression, outlined as lower than 50%, however larger than or equal to 25% expression of folate receptor alpha. We anticipate to report preliminary mixture information from this trial within the second half of 2023.
Now, allow us to flip our consideration to the progress we’ve got made in our Section 1a/1b scientific trial in sufferers with AML and high-risk MDS. On this trial, we’re evaluating the protection, tolerability, pharmacokinetics anti-tumor exercise and pharmacodynamic results of 154 as each monotherapy and together with azacitidine. As a reminder, the primary a part of this trial is a parallel staggered monotherapy and mixture dose-escalation wherein we anticipate to enroll a closely pretreated, relapsed-refractory affected person inhabitants. Enrollment within the monotherapy cohort of this trial has progressed persistently and as deliberate and importantly we dosed the primary affected person within the azacitidine mixture cohort within the fourth quarter of 2022. Preliminary information from the dose escalation portion of this trial as each monotherapy and together with azacitidine are anticipated within the first half of 2023. After we full the dose escalation portion of this scientific trial, we intend to judge 154 in a frontline affected person inhabitants setting TP53 mutant AML and frontline high-risk MDS.
With that, I’ll now flip the decision over to Mr. Neill to debate our monetary replace. Andrew?
Andrew Neill
Thanks, Lini and good afternoon, everybody. As Conor talked about on the outset of the decision, the complete monetary outcomes for the fourth quarter and full-year ended December 31, 2022 can be found in our earnings press launch and in our Annual Report on Type 10-Ok. At present, I wish to give attention to a couple of key factors from our disclosures. We proceed to be properly positioned financially. As of December 31, 2022, we had money, money equivalents and investments of roughly $161.3 million.
Within the fourth quarter of 2022, our analysis and improvement bills have been $21.9 million, in comparison with $16.2 million for the fourth quarter of 2021. For the yr ended December 31, 2022, our analysis and improvement bills have been $82.9 million as in comparison with $56.6 million for the yr ended December 31, 2021. Within the fourth quarter of 2022, our common and administrative bills have been $4.8 million in comparison with $4.6 million for the fourth quarter of 2021.
For the yr ended December 31, 2022, common and administrative bills have been $21.1 million as in comparison with $18.7 million for the yr ended December 31, 2021. Our web loss for the fourth quarter of 2022 was $25.4 million or a lack of $0.60 per fundamental and diluted share, in comparison with a web revenue of $7.8 million for the fourth quarter of 2021 or $0.19 per fundamental share and $0.18 per diluted share. Our web loss for the yr ended December 31, 2022 was $101.9 million or $2.41 per fundamental and diluted share as in comparison with $45 million or $1.07 per fundamental and diluted share for the yr ended December 31, 2021.
Primarily based on our present working and improvement plans, we reiterate our monetary steering for 2023 and past. We anticipate our current money and money equivalents and investments to be ample to fund our deliberate operations into the second half of 2024. We stay dedicated to working sturdy monetary self-discipline, together with in our ongoing scientific packages and given our projected price of money burn, we consider we’re in a wholesome place because it pertains to our stability sheet and anticipated scientific information readouts for our 154 scientific trial in 2023.
With that, I’ll now hand the decision again to Dr. Taylor Schreiber for last feedback. Taylor?
Taylor Schreiber
Thanks, Andrew. As you’ve simply heard, 2022 was a yr wherein we’re intensely targeted on the execution of our scientific packages and we’re happy to be approaching key scientific information in 2023. As you heard from Lini, scientific updates from the 154 program together with full information from the monotherapy dose-escalation trial in platinum-resistant ovarian most cancers sufferers and preliminary information together with liposomal doxorubicin additionally in ovarian most cancers sufferers are anticipated mid-year 2023. Moreover, preliminary information from our trial in-patients with AML and high-risk MDS are anticipated within the first-half of 2023. As you possibly can see, we anticipate 2023 to be a data-rich yr and we look ahead to sharing these information with you.
One of many cornerstones of Shattuck has all the time been the experience of our preclinical improvement and analysis and improvement groups. I need to spotlight the group’s large progress in 2022, resulting in the promotion of medical doctors Fromm and de Silva as Chief Scientific Officers to move the ARC and GADLEN platform analysis and improvement efforts, respectively.
Curiosity in harnessing the exercise of Gamma Delta T Cells in most cancers has continued to construct and we consider our GADLEN platform is actually distinct from all different approaches at the moment in improvement because of its distinctive design options. Throughout the fourth quarter of 2022, we highlighted two preclinical compounds from the GADLEN platform, one focusing on the CD20 antigen that we’re evaluating for improvement in autoimmune illness and a second focusing on the B7-H3 antigen for which we’re evaluating for improvement in sure stable tumors.
We look ahead to offering additional steering on the GADLEN program because it continues to advance later this yr. Along with our progress within the clinic and in our discovery efforts, I wish to underscore that our monetary place stay sturdy and we proceed to research different alternatives to monetize our portfolio to extend shareholder worth.
I wish to thank everybody for taking part in in the present day’s name. We consider that the mix of our skilled group and transformational science and protein engineering, in addition to monetary assets places us in an extremely sturdy place to maneuver past our subsequent set of milestones in 2023. We’ll preserve you apprised of our progress as we proceed to execute our strategic and company goals.
With that, we might now prefer to open the decision to your questions. Operator?
Query-and-Reply Session
Operator
Thanks, Dr. Schreiber. [Operator Instructions] We’ll take our first query this afternoon from Jonathan Miller of Evercore ISI.
Jonathan Miller
Hello, guys. Thanks a lot for taking the query. I’d love to start out with the 154 program. I do know you have been seeing some liver tox at increased doses. I’m questioning how that appears to be filling out as you progress ahead. Have you ever seen any Grade 3 or any of excessive grade, I ought to say, liver tox within the 3 mg combo cohort? And simply to construct off of that, what number of sufferers in combo do you anticipate to be accessible within the preliminary launch, particularly in AML and MDS, is it sufficient that we must always anticipate to be getting a superb ORR comp relative to different CD47’s in these releases this half?
Taylor Schreiber
Hey, Jon, thanks for the query. So I’ll – Lini can present you steering on affected person numbers arising in all of the cohorts. With regard to tox, the profile that we’re seeing in all the mixture research is just like what we’ve seen within the monotherapy dose escalation. So with regard to the precise liver toxicity query, we’re not seeing any proof of any cumulative tox between the molecules and three mg/kg was properly tolerated as monotherapy in that monotherapy dose escalation research as properly. So trying good so removed from that perspective, additionally constant profile from what we noticed within the monotherapy dose escalation with regard to no proof of cytokine launch syndrome or damaging anemias.
Lini Pandite
Then on the mix, Jon, with the AML, MDS cohort, the sufferers that we’re enrolling within the dose escalation are sufferers who’ve relapsed refractory illness. We anticipate in extra of 20 sufferers a customized monotherapy and the pump cohorts by the center of the yr. The – simply to place this in context, the CD47 focused brokers, they’ve a benchmark within the frontline setting in treatment-naive sufferers. These sufferers are relapsed/refractory sufferers. We might be beginning these growth cohorts within the frontline setting as quickly as we full the dose escalation.
Jonathan Miller
Is sensible. Thanks a lot. I’ll again in queue.
Operator
Thanks. We go subsequent now to Marc Frahm at Cowen.
Marc Frahm
Thanks for taking my questions. Perhaps I’ll ask comparable questions and however we are going to go to the Doxil combo as a result of that’s the prep check. Could also be Lini, should you may give an replace on form of the scope of that presentation or more likely to see. After which associated to that, as we get in the direction of the mirve dataset, simply in your ready remarks, Taylor, you talked about the form of authorised response price that mirvetuximab has within the bio micro chosen inhabitants, however after all, the trial goes to enroll a broader inhabitants. So, how ought to we take into consideration form of deciphering that information as we get it on condition that you’ll embrace sufferers who aren’t authorised for monotherapy plus a few of your proposed profit is basically on sturdiness not so not as a lot on the response price.
Taylor Schreiber
Nice. Thanks, Marc. Lini can deal with it for us.
Lini Pandite
Sure, with the Doxil we predict one thing within the order of 10 to twenty sufferers by the center of the yr. So based mostly – we might be sharing information each on the protection, in addition to the efficacy. Will probably be a mix of that information, relying on the enrollment. And we anticipate that we would supply some steering nearer to the time as to what to anticipate by the center of the yr. However to reply your query within the Doxil will probably be within the order of 10 to twenty sufferers. With the mirve, trying on the mirve information, so sure, I imply, with mirve authorised within the excessive expresser group, 75% of weight and right here we’re enrolling sufferers with 25% or larger. So we might be trying on the response by subgroup in these subset. However at this stage, what we’re doing with ImmunoGen is that we’re partnering with ImmunoGen to see what can be an attention-grabbing response price and sturdiness of response based mostly on their database, we will certainly be working with them to benchmark the info that we see in opposition to the datasets that they’ve. And by the top of the yr, we might hope to have or anticipate to have about 40 sufferers of price of information.
Marc Frahm
Thanks, very useful.
Operator
Thanks. We go subsequent now to Yigal Nochomovitz at Citi.
Yigal Nochomovitz
Hello, thanks. I’m simply making an attempt to get a sense for expectations for the combo research with 154 in aza each within the relapsed/refractory setting, in addition to within the frontline setting. What do you usually consider is the efficacy bar for aza by itself and with the addition of 154 in each relapsed/refractory AML and MDS in addition to within the frontline setting in TP53 mutant, what may you anticipate to see with the combo above aza?
Taylor Schreiber
Thanks, Yigal. As Lini stated within the preliminary portion of the trial, we’re enrolling primarily venetoclax to an HMA skilled topic. So any exercise in that relapsed/refractory setting, I believe can be useful and maybe present some steering towards what you may anticipate within the frontline setting. The primary two cohorts that we anticipate to have information from within the second half of this yr within the frontline setting are primary within the TP53 mutant AML sufferers. There we consider that the anticipated impact by way of full responses for azacitidine alone, are within the vary of twenty-two%. And so we’re in search of a mix full response price within the neighborhood of 40% or so. And within the high-risk MDS cohort, that is the place there continues to be a little bit of blurriness, truthfully, within the subject as to what the anticipated impact measurement of azacitidine alone is. Among the older research place that full response price within the excessive teenagers, the more moderen Takeda research with Pevonedistat counsel that it might be as excessive because the low 30s. And so we predict it’s finest to quote the upper response price because the benchmark. And so we’re in search of a mix response price someplace within the neighborhood of fifty% for full responses.
Yigal Nochomovitz
Okay, after which I’m unsure should you talked about it within the ready remarks, however simply are you able to simply form of undergo once more the selection of the three mg/kg for 154 in combo with the liposomal doxorubicin. What was driving that call?
Taylor Schreiber
So it was pushed by a couple of elements. To begin with, on each the CD40 and CD47 binding sides of the molecule, we have been trying to discover a dose the place full receptor occupancy and receptor saturation was achieved. And that was achieved by that 3 mg/kilogram dose and that was seen each by way of the receptor occupancy information and statement of non-linearity within the PK profile. Past that, we have been in search of a dose that led to maximal induction of the pharmacodynamic results pushed by CD40. So many of us are conscious that with others – with CD47 inhibitors, the one pharmacodynamic impact you see in a research like that is receptor occupancy. So the statement of fast margination of CD40 expressing cells from the peripheral blood publish dose is a novel impact for 154 relative to every other agent within the area. That was maximal by the three mg/kg dose and maintained that maximal plateau up by means of the ten mg per kg dose. The opposite major pharmacodynamic results have been fast induction of a number of cytokines, together with interleukin-12, IP-10, CCL2, CCL4, CCL22 and plenty of others. And people cytokines additionally achieved a – what seem like a maximal plateau by that 3 mg/kg dose, which didn’t escalate appreciably by the ten mg/kg dose, but additionally importantly didn’t decline. And so forth all of these markers, 154 was differentiated each from single-acting CD47 inhibitors and lacked any of the toxicity or bell-shaped dose response results that characterize prior CD40 agonist and so all of that gave us confidence about this being the fitting dose to usher in the combos.
Yigal Nochomovitz
Nice. Thanks.
Operator
Thanks. We’ll take our final query in the present day from Zhiqiang Shu of Berenberg.
Zhiqiang Shu
Good afternoon. Thanks for taking the questions. My query is said to your 252 program. Clearly, it’s not shocking to see the discontinuation there, however I used to be questioning should you can discuss concerning the learnings from this program, notably across the PK/PD facet to 154, what the PK/PD from 252 is in keeping with what you might be observing in 154? Thanks very a lot.
Taylor Schreiber
Certain, thanks. Zhi. So the trial cross comparisons listed here are, I believe, fairly useful. And with the 252 program, we accomplished dose escalation by means of that 24 mg/kg dose compound continued to be extraordinarily properly tolerated. And throughout that dose escalation, we noticed dose dependent binding to CD4 cells expressing OX40 and migration of these cells out of the peripheral blood publish dose. And so once more, from a TNF receptor agonist perspective, the tolerability and lack of any proof of a bell-shaped dose response curve and the pharmacodynamic results with each 252 and 154 are useful by way of validating one of many central hypotheses of the ARC platform that should you interact TNF receptors with a hexameric drug, you’ll not observe a few of the toxicities and pharmacodynamic – irregular pharmacodynamic results that prior antibody-based regimens have seen. In order that’s an essential discovering from a platform growth standpoint, once more each from the protection and the pharmacodynamic aspect. And we’re additionally studying some essential classes I believe by way of what OX40 and what CD40 stimulation obtain in human most cancers sufferers. And once you have a look at the 252 information and also you observe that there actually are – there have been no considerable serum cytokine modifications. The one cells that have been migrating have been the precise CD4 constructive, OX40 constructive cells. It was a way more immunologically quiet molecule, so to talk, on this affected person inhabitants, whereas the CD40 agonist clearly all throughout the dose escalation led to very clear escalations in plenty of cytokines, infusion-related reactions have been rather more frequent with that agent. And so the differentiation in biology between the 2 constructs paints a really clear image that that is target-mediated exercise that we’re seeing right here. So all the time exhausting to shut down a program like this, however I believe we’ve realized what we would have liked to be taught from this molecule and people learnings will profit different compounds transferring ahead.
Zhiqiang Shu
Nice. Thanks. After which perhaps simply rapidly on GADLEN platform, you disclosed, I believe in keeping with final time that you’ve two preclinical assay. Are you able to speak about kind of the prioritization there and once we can see extra information or extra improvement from these two packages?
Taylor Schreiber
So the B7-H3 molecule is the one we’re contemplating for improvement in oncology and the CD20 is the one which we’re contemplating for improvement in antibody-mediated autoimmune illness. And what we’re in search of to attain with the preliminary scientific research with the GADLEN platform is to pick out a sign the place we consider will probably be almost certainly {that a} GADLEN molecule will differentiate from CD3-based T cell engagers, antigen-specific antibody molecules and we’ve realized lots about what Gamma Delta T Cells rely on to be totally activated. And identical to alpha beta T cells, they require a T cell receptor stimulus, which comes from the GADLEN molecule itself and the butyrophilin heterodimer. And so they additionally require a co-stimulatory ligands to be expressed by their goal cell. And so part of the train that’s guiding the trouble is tumors that categorical B7-H3 and making an attempt to guarantee that sufferers that we’d enroll early in a Section 1 dose escalation research are more likely to categorical these sign to ligands on their tumor. And that’s on the tumor aspect and on the autoimmune aspect, you possibly can have certainty really that any B-cell, which expresses CD20 can even categorical a sign to ligand within the type of CD80 or 86. And so these are a few of the design ideas that we take into consideration for that Section 1 trial and we might be offering extra particular steering as to precisely what that research goes to seem like within the short-term this yr.
Zhiqiang Shu
Nice. Thanks, Taylor.
Taylor Schreiber
Thanks.
Operator
Thanks. This concludes the Q&A session of the decision. Presently, I wish to flip the decision again over to Taylor Schreiber, Chief Government Officer of Shattuck Labs for closing remarks.
