Q2 2022 CytomX Therapeutics Inc Earnings Call
Okay.
Good afternoon, everyone.
Good afternoon, everyone. Thank you for standing by and welcome to the Pfizer next therapeutics second quarter 2022 financial results call. Please be advised that today's call is being recorded.
Thank you for standing by.
Welcome to the CytomX Therapeutics second quarter 2022 financial results call.
We continue to believe, based on the progress we've made and based on discussions that we have over time, that our technology is extremely relevant.
Please be advised that today's call is being recorded.
I think if you look at the evolution of the ADC field, the evolution of the T-Cell Engager, and even co-stimulatory field that we heard about yesterday from Regeneron, and also the evolution of the cytokine field, you know, we have a technology platform that we continue to believe can add significant value to these three areas.
I'd like to hand, the call over to your host for today Chau Cheng types of Lexus, Vice President Investor Relations and corporate Communications. Please go ahead.
So, you know, there should be opportunities over the course of our cash runway, should we choose to take them, to do additional deals that could generate non-dilutive capital.
I'd now like to hand the call over to your host for today, Chow Cheng, CytomX's Vice President,
We'll see, I've always said, we'll do the right deals at the right time.
Thank you.
Good afternoon, and thank you for joining us.
Before we begin I'd like to remind everyone that during this call we will be making forward looking statements.
Investor Relations and Corporate Communications.
Thus far looking statements relates to the future. They are subject to inherent uncertainties and risks that are difficult to predict and many of which are outside of our control.
Important risks and uncertainties are set forth in our most recent public filings with the SEC at SEC.
<unk> Dot Gov.
We undertake no obligation to update any forward looking statements.
Results of new information future developments or otherwise.
Earlier. This afternoon, we issued a press release that includes a summary of our second quarter 2022 financial results and highlight recent developments at the company.
We encourage everyone to read today's press release and associated materials, which have been filed with the SEC.
Additionally.
The press release and a recording of this call can be found in the investors and news section of our website.
With us on our call today, I felt a strong Mccarthy <unk>, Chief Executive Officer and Chairman.
Carlos Campoy Chief Financial Officer.
With that let me turn the call but to Sean.
Yes.
Please go ahead.
With regard to bringing in technology, you know, we continue to follow the conditional activation space very carefully.
Thank you Joe and good afternoon, everyone. Thanks for joining us for an update on recent progress.
Thank you, Yoora.
Yeah.
The foundation of our work at <unk> is to destroy cancer differently.
Good afternoon and thank you for joining us.
With our innovative priority therapeutic platform, we have blaze, a new trail in oncology R&D and is now generally accepted that the conditional activation of biologics offers tremendous opportunity for the development of new cancer Therapeutics.
Sigh Terminix, we firmly believe that our multi modality property platform has the potential to deliver differentiated medicines for the treatment of people with cancer.
Before we begin, I'd like to, remind everyone that during this call, we will be making forward-looking statements. Because forward-looking statements relate to the future, they are subject to inherent, uncertainties and risks that are difficult to predict, and many of which are outside of our control. Important risks and uncertainties are set forth in our most recent public filings with the SEC at sec.gov.
I think we're in pretty good shape there in terms of, you know, the investments we've made internally.
To ensure <unk> remains well positioned for the future as announced last month, we have made a series of recent changes with the organization to prioritize our R&D investments and capitalize on our extensive clinical experience to date with our platform technology.
We undertake no obligation to update any forward-looking statements, whether as a result of new information, future developments, or otherwise.
We have an industry-leading platform, and so I can't really comment on any other activities that we may have there at this stage.
Earlier this afternoon, we issued a press release that includes a summary of our second quarter, 2022 financial results and highlights recent developments at the company.
Great, thank you.
We encourage everyone to read today's press release and the associated materials, which have been filed with the SEC. Additionally, the press release and the recording of this call can be found under the Investors and News section of our website.
With us on the call today are Dr. Sean McCarthy, CytomX's Chief Executive Officer and Chairman, and Carlos Campoy, Chief Financial Officer.
With that, let me turn the call over to Sean.
You're
Our restructured pipeline holds much promise for people with cancer and continues to spend preclinical stage to phase III.
CX two there are two nine is in the later stages of phase II expansions and enrollment into the solid tumor cohorts has been completed.
Thank you, Chow, and good afternoon, everyone.
welcome.
Our collaborative work with Bristol Myers Squibb continues including the randomized phase II study of BMS 98, six to 49, and we are also well underway with phase one dose escalation for CX 904, our Egfr CD three T cell engaging by specific.
Thanks for joining us for an update on, recent progress at CytomX.
In regards to our earlier stage pipeline, our recent decision to de prioritize <unk> Tenzing now enables us to focus our resources and capital towards two exciting new wholly owned programs CX 801, and CX 2051.
And I'd like to spend a few moments focusing on these new opportunities.
Okay.
CX 801 is our conditionally activated interferon alpha <unk> the lead program within our broad efforts in the cytokine field.
Interferon Alpha <unk> is an approved immuno therapeutic that is demonstrated clinical activity in multiple cancer types and we believe provides an orthogonal and potentially superior approach to cytokines like IL, two IL 12, and IL 15, and activating antitumor immune responses.
At the cellular level interferon alpha potently stimulates antigen presenting cells to activate cytotoxic T cells.
Furthermore, interferon alpha combined effectively with checkpoint inhibition and offers tremendous potential to unlock checkpoint refractory and resistant cancers.
Despite this potential however, the systemic toxicity of interferon Alpha is limited as used to date.
With therefore excited to have created CX 801, our conditionally activated master version of interferon Alpha <unk> designed to harness the powerful activity of this potent immune modulator by increasing its therapeutic window.
The broad therapeutic window of CX 801 was highlighted in a poster presentation at ACR earlier this year and we entered rapidly advanced this potentially best in class program towards clinical evaluation with IND filing targeted for the second half of 2023.
Switching now to 2051, <unk> thousand 51, a conditionally activated antibody drug conjugate targeting <unk> with potential applicability across <unk> expressing epithelium cancers.
<unk> has been regarded as a high potential oncology target for decades and has been clinically validated by others.
For example, the locally administered anti <unk> antibody toxin fusion protein opportunism at mono Tox has demonstrated robust clinical activity and non muscle invasive bladder cancer.
However efforts to generate systemic anti <unk> therapeutics have to date not been successful due to toxicity to epithelial tissues.
This is because <unk> or epithelial cell adhesion molecule as the name suggests is present on the majority of normal epithelium cells and conventional anti account biologics administered systemically have significant dose limiting toxicities.
We are applying the learnings from our clinical studies with <unk> and CX two zero to nine in the design of CX 2051, and we'll have more to say about the molecular configuration of this drug candidate in the future.
We plan to file an IND for this novel ADC in the second half of 2023.
A key theme that connect our two newest programs CX 801, and CX 2051 is that both targets have a level of validation that we believe increases the probability of future clinical success and we are excited to be moving these programs forward.
Okay.
Now returning to our later stage pipeline, where we continue to work intensively with our partners to advance multiple novel programs in the clinic.
This past quarter, we introduced into the clinic CX 904.
Third therapeutic modality from our versatile property platform.
CX 904, which is partnered with Amgen is our conditionally activated T cell engaging by specific antibody designed to target. The CD three receptor on T cells, and the epidermal growth factor receptor on cancer cells.
This target combination is intended to activate antitumor T cell responses in Egfr positive cancers.
In Q2, we treated the first patient with CX 904, and phase one dose escalation is ongoing with the goal of assessing safety and selecting our go forward dose with subsequent expansions.
Moving on to BMS 986 to 49 or <unk> four targeting property candidate licensed to Bristol Myers Squibb.
CCI for targeted therapy, as a foundational immuno oncology strategy and treatment with <unk> as a monotherapy or in combination with Novo has resulted in clinically meaningful antitumor activity in a variety of malignancies.
The durability of responses to anti <unk> four therapy continues to highlight the importance and uniqueness of this target.
However, <unk> four blockade has a narrow therapeutic window and we believe that broader potential of CCI for therapy could be realized through the application of our property platform.
Okay.
BMS continues to evaluate 249 in a randomized phase II study in combination with <unk> versus AP, plus <unk> in patients with newly diagnosed advanced melanoma.
BMS previously reported phase one safety data for 249 at <unk> 2020, showing the Cta for targeting <unk> was well tolerated at elevated doses, both as monotherapy and also in combination with <unk>.
Yes.
At ESMO 2020 to BMS plans to present updated phase one results for 249 in a poster presentation.
In early 2021, BMS extended the evaluation of 249, plus <unk> to advanced hepatic cellular carcinoma, castration resistant prostate cancer and triple negative breast cancer.
And BMS also continues to study BMS 906 to eight eight the non few calculated cta for targeting <unk>.
In a phase one dose escalation study both as monotherapy and also in combinations NEVA with levo in patients with advanced solid tumors.
Now continuing on <unk>, nine or <unk> 71, or transferrin receptor directed ADC, which is partnered with Abbvie.
Enrolment into the overall CX two zero to nine phase II expansion study has now met its objectives in all three solid cancer indications, including the esophageal gastroesophageal junction cancer cohort.
The diffuse large b cell lymphoma cohort has been de prioritized due to strategic and competitive reasons and did not enroll any patients.
A data update for the squamous lung cohort is expected in the fourth quarter of 2022 and data from the esophageal and gastroesophageal junction cancer cohort continues to mature.
At this time, I would like to hand the call back over to Chao Chang for his closing remarks.
With that let me hand over to Carlos who will provide you with a financial overview for the quarter.
So, on behalf of the executive team, I'd like to thank you all very much for joining us this afternoon.
Thank you Sean.
<unk> starting at 2000, 2002, we had $228 million in cash cash equivalents.
We look forward to updating you in the future on our ongoing progress.
Our recently announced restructuring efforts as Sean mentioned earlier should allow us to extend our cash runway into 2025.
This runway forecast does not include any potential upfront and milestone payments from existing or future partnerships.
For the second quarter of 2020, Q revenue was about $18 million compared to the $16 million for the corresponding period in 2021.
The increase was largely related to the <unk> 71 in collaboration with Abbvie.
R&D expenses increased $5 million and $31 million during the three months ended June 32022, compared to Q2 2021.
The increase was primarily due to higher personnel related expenses and laboratory contract services in support of our preclinical and clinical pipeline.
G&A expenses were $11 seven.
During the second quarter of 2022, an increase of $2 $4 million over Q2, 2021 increases mainly in personnel and professional.
This does conclude today's conference call.
I will now turn the call back to Sean.
Thanks Carlos.
In closing we believe our recent decision to restructure <unk> puts us in the strongest possible position to maintain our technological leadership and conditional activation of oncology therapeutics and to advance our robust pipeline with substantial potential for patients.
Thank you for participating.
You may now
We're proud of the significant progress we continue to make building on the consistent achievement of technical milestones, including six <unk> filed across three therapeutic modalities for programs that have advanced to phase II studies in more than 500 cancer patients who have been treated with our product candidates to date.
Our corporate partnerships remains strong and we will continue to emphasize new business development is an integral part of our corporate strategy.
As we've said before we care for every patient we learn from every patient and we deeply thank everyone involved in our efforts to make the biggest difference. We can we are committed to destroying cancer differently for the benefit of people living with cancer and we remain firmly focused on building <unk> for the long term.
The foundation of our work at CytomX is to destroy cancer differently.
With our innovative ProBody therapeutic platform, we have blazed a new trail in oncology R&D, and it's now generally accepted that the conditional activation of biologics offers tremendous opportunity for the development of new cancer therapeutics.
At CytomX, we firmly believe that our multi-modality ProBody platform, has the potential to deliver differentiated medicines for the treatment of people with cancer.
To ensure CytomX remains well-positioned for the future, as announced last month, we have made a series of recent changes with the organization to prioritize our R&D investments and capitalize on our extensive clinical experience to date with our platform technology.
Our restructured pipeline holds much promise for people with cancer, and continues to span preclinical stage to phase 2.
CX2029 is in the later stages of phase 2 expansions, and enrollment into the solid tumor cohorts has been completed.
disconnect, and have a great day.
Operator, let's now open the call up for questions.
Anupam Rama: Anupam Rama, Lukas Shumway, CytomX Therapeutics Inc. [inaudible] Diolch yn fawr iawn am wylio'r fideo.
Unknown Executive: Diolch ar Feyw.
Thank you in order to ask a question. Please press Star then the number one on your telephone keypad at stall and one if you wish to ask a question.
Unknown Executive: 6.
First question comes from the line of Paul Mountain <unk>. Please ask your question.
Unknown Executive: Diolch ar ffotograff et ffonfradd.
Our collaborative work with Bristol-Myers Squibb continues, including the randomized, phase 2 study of BMS986249, and we're also well underway with phase 1 dose escalation to CX904, our EGFR-CD3 T-cell-engaging bispecific.
Unknown Executive: Diolch am annu ddiogel.
Yes. Good afternoon, thanks for the update and for taking my question.
CX nine four can you provide any insight into the study that's ongoing are you.
Starting with therapeutically relevant doses and how many dose levels you plan to test.
Unknown Executive: Diolch i ffotograffet ar gyfran.
Yes, Hi, Kerry Thanks for the question. So we're obviously very pleased with the progress on 904 now being in the clinic and in the early stages of dose escalation.
In regards to our earlier stage pipeline, our recent decision to deprioritize, praluzetamab raftanzine now enables us to focus our resources and capital towards two exciting new wholly-owned programs, CX801 and CX2051, and I'd like to spend a few moments focusing on these new opportunities.
Unknown Executive: A gogasch yn y revisiwn.
Unknown Executive: Diolch am wylio'r fideo.
CX801 is our conditionally activated interferon alpha 2B, the lead program within our broad, efforts in the cytokine field. Interferon alpha 2B is an approved immunotherapeutic that has demonstrated clinical activity in, multiple cancer types and, we believe, provides an orthogonal and potentially superior approach to cytokines like IL-2, IL-12, and IL-15 in activating antitumor immune responses. At the cellular level, interferon alpha potently stimulates antigen-presenting cells to activate, cytotoxic T cells. Furthermore, interferon alpha combines effectively with checkpoint inhibition and offers tremendous, potential to unlock checkpoint refractory and or resistant cancers.
Luke Shumway: Unknown Executive, Anupam Rama, Luke Shumway, Christopher Ogden, Unknown Executive, Anupam Rama, Etzer Darout, Roger Song, Jade Montgomery, Luke Shumway, CytomX Therapeutics Inc, .
Despite its potential, however, the systemic toxicity of interferon alpha has limited, its use to date. We're therefore excited to have created CX801, a conditionally activated massed version of, interferon alpha 2B designed to harness the powerful activity of this potent immune modulator by increasing its therapeutic window.
The broad therapeutic window of CX801 was highlighted in our poster presentation at, AACR earlier this year, and we aim to rapidly advance this potentially best-in-class program towards clinical evaluation with IND filing targeted for the second half of 2023.
Switching now to 2051, CX2051, a conditionally activated antibody drug conjugate targeting, EpCAM with potential applicability across EpCAM-expressing epithelial cancers. EpCAM has been regarded as a high-potential oncology target for decades and has been clinically, validated by others. For example, the locally administered anti-EpCAM antibody toxin fusion protein, Opituzumab, monotox, has demonstrated robust clinical activity in non-muscle-invasive bladder cancer. However, efforts to generate systemic anti-EpCAM therapeutics have, to date, not been successful, due to toxicities to epithelial tissues. This is because EpCAM, or epithelial cell adhesion molecule, as the name suggests, is, present on the majority of normal epithelial cells, and conventional anti-EpCAM biologics administered systemically have significant dose-limiting toxicities.
Haven't disclosed any significant details of the phase one strategy.
Just yet.
I can say, though that.
We are starting at a pretty low starting dose we do think it's important to be.
To be thoughtful in dose escalation with a modality like this and I think that's very consistent.
With for example, the updates the exciting update we heard yesterday from Regeneron regarding their co stimulatory strategies as well in terms of.
What needs to take a step wise and learn in a very progressive way.
Got it and maybe a follow up based on your preclinical safety studies, what toxicity and our DLT UX.
And in terms of Crs rate is there something you can point to that you would clearly say beforehand is good data.
We haven't really guided on.
We're applying the learnings from our clinical studies with Praluzatamab rabtanzine and CX2029, in the design of CX2051, and we'll have more to say about the molecular configuration of this drug candidate in the future.
We plan to file an IND for this novel ADC in the second half of 2023. A key theme that connects our two newest programs, CX801 and CX2051, is that both targets have, a level of validation that we believe increases the probability of future clinical success, and we are excited to be moving these programs forward.
Good data is going to look like like I said, I think we need to take this program.
Now returning to our later stage pipeline, where we continue to work intensively with, our partners to advance multiple novel programs in the clinic. This past quarter, we introduced into the clinic CX904, the third therapeutic modality, from our versatile ProBody platform, platform. CX904, which is partnered with Amgen, is our conditionally activated T cell engaging by specific antibody designed to target the CD3 receptor on T cells and the epidermal growth factor receptor on cancer cells.
Stepwise.
I would emphasize that this is a phase one study.
This target combination is intended to activate anti-tumor T cell responses in EGFR positive cancers. In Q2, we treated the first patient with CX904 and phase one dose escalation is ongoing with the goal of assessing safety and selecting a go-forward dose for subsequent expansions.
With a molecule that we expect to be highly potent as a T cell engagement and so we are laser focused in phase one on safety.
Moving on to BMS986249, our CTLA-4 targeting pro-body candidate licensed to Bristol-Myers Squibb.
CTLA-4 targeted therapy is a foundational immuno-oncology strategy and treatment with ipilimumab as a monotherapy or in combination with NEVO has resulted in clinically meaningful anti-tumor activity in a variety of malignancies.
The durability of responses to anti-CTLA-4 therapy continues to highlight the importance, and uniqueness of this target.
However, CTLA-4 blockade has a narrow therapeutic window and we believe that broader potential of CTLA-4 therapy could be realized through the application of our pro-body platform.
The.
Data that we presented previously.
On this general therapeutic concept of Egfr CD three.
It is.
It's actually a different preclinical molecule, we haven't disclosed yet the data or the.
The architecture, if you like of 904, we will do so in the future, but if you look at that previously disclosed data on the therapeutic concept of Egfr CD three we're obviously very focused on on cytokine induction and you can see in that previously.
<unk> data very very substantial shifts in.
And improvements in safety with the marketing strategies that we've employed but of course in the clinic will be focused on.
All of these parameters.
As we move carefully and thoughtfully through this initial dose escalation phase.
Got it thank you.
Your next question comes from the line of Frank Okay.
Okay David.
<unk>.
BMO capital markets. Your line is now.
Okay.
Great. Thank you for the question. So just wanted to get an update from you on sort of bench.
Benchmarks for the CX 2029 data in squamous cell non small cell lung cancer and I guess, what you would characterize as good data unless upcoming update in the fourth quarter. Thank you.
Yes, hi, thanks, Thanks for the question.
I think as we've discussed previously in the data released that we presented towards the end of last year.
Just to recap that data.
We presented.
Advanced data on 16.
Efficacy evaluable patients towards the goal ultimately of enrolling 25.
In that particular cohort and we have announced previously that we are and reiterated today that we fully enrolled that cohort but.
But at the time of those 16 efficacy evaluable patients. We saw a response rate of just under 19%. So we sold three.
<unk> partial responses and we had guided previously going into that update last year that a response rate.
The 20% range would be would be clinically significant and very meaningful and so we're right in that ballpark with that initial result, one could argue actually at that benchmark could even be a little bit lower maybe towards 15% why is that well because the patients that were enrolled.
All 16 patients at.
Prior checkpoint inhibitor experience and this is an emerging of course patient population, where the unmet need is very significant.
One would expect responses to chemo for example to be in the low double low double digits, so with the full cohort.
Data that full 25 patients will be will be very pleased if we maintain the response rate in the range of what we've already disclosed.
Great. Thank you.
Thank you.
And our next question comes from the line of Morocco.
Mr. <unk> your line is open.
Hi, and this is a poet samira.
My first question is on the CX two tier two nine.
How do you plan to disclose the data in the fourth quarter.
Hi.
Is it going to be like similar to last year by the press release or is it going to be at the conference menu have you decided on that.
No comment on that at this point.
As you can hear we are maintaining our guidance presenting or sharing data by the end of the year.
We will be.
Now that the <unk>.
We've announced today now that the enrollment into the <unk>.
All three of the solid tumor cohorts, specifically head and neck lung.
Salford Gilles has been completed we will obviously be sitting down with our partner Abbvie.
Later in the year to review data and start to think about next steps.
Disclosure strategy will be a part of that discussion as well so theres no additional comment I can make at this stage.
Got it got it and then one more on that.
With regard to the south of <unk>.
When do you expect that had been showing up to be disclosed publicly.
Yes, I cant comment on that yet other than to say that the cohort is fully enrolled and the data continues to mature.
Got it.
And then one more on BMS.
BMS continues to evaluate 249 in a randomized phase two study in combination with NEVO versus IPI plus NEVO in patients with newly diagnosed advanced melanoma. BMS previously reported phase one safety data for 249 at ASCO 2020, showing the CTLA-4 targeting pro-body was well tolerated at elevated doses, both as monotherapy and also in combination with NEVO.
<unk> two <unk> I was wondering if you can maybe additional color on the type of data that you plan to do.
<unk> in Brazil plasma chat.
Perhaps a bit more color in terms of the tumors breakdown.
Great.
Well there's.
Two things to say, there one which we mentioned in the call today that.
BMS did present the phase one.
At ESVO 2022, BMS plans to present updated phase one results for 249 in a poster presentation.
Safety data at <unk> 2020.
In early 2021, BMS extended the evaluation of 249 plus NEVO to advanced hepatocellular carcinoma, castration resistant prostate cancer, and triple negative breast cancer.
And BMS also continues to study BMS 986288, the non-fucosylated CTLA-4 targeting pro-body in a phase one dose escalation study, both as monotherapy and also in combination with NEVO in patients with advanced solid tumors.
<unk> will be presenting an update on the phase one study, which obviously is now considerably more mature.
Now continuing on to CX2029, our CD71 or, transferrin receptor directed ADC, which is partnered with AbbVie. Enrollment into the overall CX2029 phase two expansion study has now met its objectives in all three solid cancer indications, including the gastroesophageal junction cancer cohort.
The diffuse large B cell lymphoma cohort has been deprioritized due to strategic and competitive reasons and did not enroll any patients.
A data update for the squamous lung cohort is expected in the fourth quarter of 2022, and data from the esophageal and gastroesophageal junction cancer cohort continues
At ESMO coming up in a few weeks.
With regard.
to mature.
As has been previously disclosed that patient population was a fairly typical.
As one.
Study population for evaluating <unk>.
<unk> immunotherapy so.
At the usual.
Mixed bag of tumor types.
Of course, the phase II study that Theyre running the randomized phase II study of 249 is being conducted in frontline metastatic melanoma.
That study continues to enroll and we will provide an update on timing of data as and when we have it.
Got it thank you.
With that, let me hand over to Carlos, who will provide you with a financial overview for the quarter.
Your next question comes from the line of Mitchell Kapoor from H C. Wainwright. Your line is open.
Alright. Thank you for taking the questions I just wanted to know if you can remind us the differentiation the second at Cam ADC versus that first generation and what cancers like the best fit for this program based on the design of the second generation.
Thank you, Sean.
Yeah, Thanks, Mitch for the question.
So I think you're referring to we have previously discussed and in fact, we presented some data on a.
On a on a program we call CX 2043, and anti <unk>.
Priority drug conjugate will conditional ADC with the payload.
Maytansine payload <unk> 'twenty one.
Very.
Important and impressive data set pre clinically.
We have.
Moved on from that particular configuration to 2051, which we believe will have a need.
Even broader therapeutic window, and we were not yet ready to disclose the molecular architecture of 2051, we will have a presentation at the World ADC conference coming up in San Diego in September and we will be say more about 2051.
At that conference in the context of the learnings that we have here. The many learnings we have from the 2009 and 2029 programs.
In the clinic.
Thank you and for the squamous non small cell lung cancer data.
Could you kind of walk us through what expectations you might expect to see if you were to look at patients by CD 71 status and to the degree that you can comment on those analyses that we might see in the dataset.
That would be helpful.
Right. So of course as with any new target like a CD 71, we are highly interested in studying and understanding any relationship between target biology, and anticancer activity that work is ongoing.
I can't say, yet when we'll be ready to share that data at the study.
Analysis is continuing but that is something that is of course of high interest to us.
Thank you so much John .
Youre welcome.
Your next question comes from the line of Pizza Nelson from Barclays. Your line is open.
Hey, good afternoon, guys. Thanks for taking the question. This is Alex on for Peter.
Two questions from me just on CX <unk> $2 nine.
The data in lung cancer.
Wondering if you could speak a little bit about safety.
Specifically anemia.
And if you could talk about.
Would be acceptable in terms of a rate greater than EMEA to make this program going forward.
Yes, hi, Alex Thanks for the question.
No.
Something that we continue to learn.
Learn about continue to evaluate.
<unk>.
In regards to understanding.
Mechanistically.
The anemia and also potential mitigation strategies, we discussed this quite a bit in the past.
Our previously reported clinical work the anemia has been managed through various means including dose reductions those delays erythrocyte stimulating agents. We did conclude early this year that probably the Isa route is unlikely.
To help as much as we might have liked we continue to look at dose reductions those delays and what we look at the full data set across all of the.
Solid tumor cohort, so I think it will be in a better position to comment.
A little bit later in the year.
Okay, great. Thank you and then just a second question on business development.
<unk>.
Previously you talked about remaining active in BD discussions, you've obviously have a number of partnerships.
Or your partner your technology I'm, just wondering if you could.
Speak to any interest in terms of looking at.
Bringing in new technology externally or are you mostly focusing on.
Partnering your technology to larger pharma players. Thank you.
Okay.
Yes, so great question and I think a.
A couple of different different components to that question. So first of all.
I would emphasize that the restructuring that we have announced recently.
As of June 30th, 2022, we had $228 million in cash, cash equivalents, and investments. Our recently announced restructuring efforts that Sean mentioned earlier should allow us to extend our cash runway to 2025. This runway forecast does not include any potential upfront or milestone payments, from existing or future partnerships.
For the second quarter of 2022, revenue was $18 million compared to the $16 million for, the corresponding period in 2021. The increase was largely related to the CD71 collaboration with AbbVie.
R&D expenses increased $5 million to $31 million during the three months ended June 30, 2022, compared to Q2 2021. The increase was primarily due to higher personnel-related, expenses and laboratory contract services in support of our preclinical and clinical pipeline.
Just just reemphasize that that puts us in a robust cash position into 2025 and that does not assume.
G&A expenses were $11.7 million during the second quarter of 2022, an increase of $2.4 million over Q2 2021. The increase was mainly in personnel and professional expenses.
That guidance does not assume any additional business development.
Let me now turn the call back to Sean.
Cash inflows or any or indeed, any milestones from any existing deals that we have.
We do continue to be interested in leveraging the platform for additional business development in a strategic way.
Thanks, Carlos.
In closing, we believe our recent decision to restructure CytomX puts us in the strongest possible position to maintain our technological leadership in conditional activation of oncology therapeutics and to advance our robust pipeline with substantial potential for patients.
We continue to believe.
Based on the progress we've made and based on discussions that we have over time that our technology is extremely relevant I think if you look at the evolution of the ADC field the evolution of the.
We're proud of the significant progress we continue to make, building on the consistent achievement of technical milestones, including six INDs filed across three therapeutic modalities, four programs that have advanced to phase two studies, and more than 500 cancer patients who have been treated with our product candidates to date.
Our corporate partnerships remain strong, and we will continue to emphasize new business development as an integral part of our corporate strategy.
T cell engaging <unk>.
Even co stimulatory field that we heard about yesterday from Regeneron Andrew.
And also the evolution of the cytokine field, we have a technology platform that we continue to believe can add significant value to these three areas. So there should be opportunities over the course of our cash runway.
We choose to take them to do additional.
The deals that could generate non dilutive capital.
We'll see I've always said it will do the right deals at the right time.
With regard to bring in technology, we continue to follow.
The conditional activation space very carefully I think we're in pretty good shape there in terms of.
The investments we've made internally, we have an industry leading platform.
And so I can't really comment on any other activities that we may have there at this stage.
Great. Thank you.
Youre welcome.
At this time I would like to hand, the call back over to Chau Cheng from <unk>.
As we've said before, we care for every patient, we learn from every patient, and we deeply thank everyone involved in our efforts to make the biggest difference we can.
His closing remarks.
So on behalf of the executive team I would like to thank you all very much for joining us. This afternoon, we look forward to updating you in the future on our ongoing progress.
This does conclude today's conference call. Thank you for participating you may now disconnect and have a great day.
Okay.

We are committed to destroying cancer differently for the benefit of people living with cancer, and we remain firmly focused on building CytomX for the long term.
Operator, let's now open the
call up for questions.
Thank you.
In order to ask a question, please press star then the number one
on your telephone keypad.
That's star and one if you wish to ask a question.
Your first question comes from the line of Kaveri Polman from BTIG.
Please ask your question.
Yeah, good afternoon.
Thanks for the updates and for taking my questions.
For CX904, can you provide, any insight into the study that's ongoing?
Are you starting with therapeutically relevant doses, and how many dose levels do you plan to test?
Yes.
Hi, Kaveri.
Thanks for the question.
So, we're obviously very pleased with the progress on 904 now being in the clinic and in the early stages of dose escalation.
You know, we haven't disclosed any significant details of the phase one strategy just yet.
I can say, though, that we are starting at a pretty low starting dose. We do think it's important to be, you know, to be thoughtful in dose escalation with a modality, like this.
And I think that's very consistent with, for example, the exciting update we heard yesterday from Regeneron regarding their co-stimulatory strategies as well in terms of, you know, one needs to take it stepwise and learn in a very progressive way.
Got it.
And maybe a follow-up.
Based on your preclinical safety studies, what toxicities, and or DLTs you expect to see?
And in terms of CRS rates, is there something you can point to that you would clearly say beforehand is good data?
We haven't really guided on what good data is going to look like.
Like I said, I think, we need to take this program stepwise.
I would emphasize that this is a Phase I study with a molecule that we expect to be highly potent as a T cell engager.
And so we are laser-focused in Phase I on safety.
The data that we've presented previously on this general therapeutic concept of EGFR and CD3 is actually with a different preclinical molecule.
We haven't disclosed yet the data or the architecture, if you like, of 904.
We will do so in the future.
But if you look at that previously disclosed data on the therapeutic concept of EGFR and CD3, we're obviously very focused on cytokine induction.
And you can see in that previously presented data very, very substantial shifts in improvements in safety with the masking strategies that we have employed.
But of course, in the clinic, we'll be focused on all of these parameters as we move carefully and thoughtfully through this initial dose escalation phase.
Got it.
Thank you.
Our next question comes from the line of Etter Davout from BMO Capital Markets.
Your line, is now open.
Great.
Thank you for the question.
So just wanted to get an update from you on sort of, you know, benchmarks for the CX2029 data in squamous cell non-small cell lung cancer and I guess what you would characterize as good data on this upcoming update in the fourth, quarter.
Thank you.
Yes.
Hi, Etter.
Thanks for the question.
So I think as we've discussed previously in the, data release that we presented towards the end of last year, just to recap that data, we presented, announced data on 16 efficacy-evaluable patients towards the goal ultimately of enrolling 25 in that particular cohort.
And we've announced previously that we are now and reiterated today, that we fully enrolled that cohort.
But at the time of those 16 efficacy-evaluable patients, we saw a response rate of just under 19%. So we saw three confirmed partial responses.
We had guided previously going into that update last year that a response rate of the 20% range, would be clinically significant and very meaningful.
And so we're right in that ballpark with that initial result.
One could argue actually that that benchmark could even be a little bit lower, maybe towards 15%.
And why is that?
Well, because the patients that were enrolled, all 16 patients had prior checkpoint inhibitor experience.
And this is an emerging, of course, patient population where the unmet need is very significant, where one would expect responses to chemo, for example, to be in the low double digits.
So with the full cohort data, the full 25 patients, we'll be very pleased if we maintain the response rate in the range of what we've, already disclosed.
Great, thank you.
Thank you.
And our next question comes from the line of Mara Goldstein from Mizuho.
Your line is open.
Hi, this is Sopoet from Mara.
My first question is on the CX2029.
How do you plan to disclose the data in the fourth quarter?
Is it going to be like similar to last year by the press release or is it going to be at the, conference venue?
Have you decided on that?
No comment on that at this point.
As you can hear, we're maintaining our guidance of presenting or sharing data by the end of the year.
You know, we will be, you know, now that the, as we've announced today, now that the enrollment, into the, all three of the solid tumor cohorts, specifically head and neck, lung, and esophageal has been completed, we'll obviously be sitting down with our partner at V later in the year to review data and start to think about next steps.
And, you know, disclosure strategy will be a part of that discussion as well.
So there's no additional comment I can make at this stage.
Got it.
Got it.
And then one more on that.
So with regards to the esophageal and GEJ, when do you expect the data to be mature enough to be disclosed publicly?
Yeah, can't comment on that yet, other than to say that the cohort is fully enrolled and, the data continues to mature.
Got it.
And then one more on BMS, 96249.
I was wondering if you can provide maybe additional colors on, you know, on the type of
data that you plan to share or, you know, do in Bristol plan to share and, you know, perhaps a bit more colors in terms of the tumors breakdown, if you could.
Well, there's two things to say there.
One, which we mentioned in the call today that, you know, BMS did present the phase one safety data at ASCO 2020.
They will be presenting an update on the phase one study, which obviously is now considerably more mature at ESMO coming up in a few weeks.
With regard, and as has been previously disclosed, that patient population was a fairly typical, you know, phase one study population for evaluating, you know, novel immunotherapy. So the usual mixed bag of tumor types.
Of course, the phase two study that they're running, the randomized phase two study of 249, is being conducted in frontline metastatic melanoma.
That study continues to enroll, and we will provide an update on timing of data as and when we have it.
Got it.
Thank you.
And your next question comes from the line of Mitchell Kapoor from HC Wainwright.
Your line is open.
Hi, thank you for taking the questions.
I just wanted to know if you, could remind us of the differentiation of the second Epcam ADC versus the first generation, and what cancers might be a best fit for this program based on the design of the second generation?
Yeah, thanks, Mitch, for the question.
So I think you're referring to, you know, we previously discussed, and in fact we presented, some data on a program we call CX2043, an anti-EPCAM pro-body drug conjugate, or conditional ADC, with the payload, the Maitanzin payload, DM21, you know, very important and impressive, data set preclinically.
We have moved on from that particular configuration to 2051, which we believe will have an even, broader therapeutic window, and we're not yet ready to disclose the molecular architecture of 2051.
We will have a presentation at the World ADC Conference coming up in San Diego in September, and we will be saying more about 2051 at that conference in the context of the learnings that we have, the many learnings we have from the 2009 and 2029 programs in the clinic.
Thank you.
And for the squamous non-small cell lung cancer data, could you kind of walk us through what, expectations you might expect to see if you were to look at patients by CD71 status, and to the degree that you could comment on those analyses that we might see at the data set?
That would be helpful.
Right.
So, of course, as with any new target, like a CD71, we are highly interested in studying, and understanding any relationship between target biology and anti-cancer activity.
That work is ongoing.
I can't say yet when we'll be ready to share that data.
The study analysis is continuing, but that is something that is, of course, of high interest, to us.
[music].
Thank you so much, John.
You're welcome.
Our next question comes from the line of Peter Lawson from Barclays.
Your line is open.
Hey.
Good afternoon, guys.
Thanks for taking the question.
This is Alex on for Peter.
Two questions for me.
Just on CX2029, the update in lung cancer, wondering if you could speak a little bit, about safety and specifically anemia, and if you could talk about, you know, what would be acceptable in terms of a rate and grade of anemia to make this program move forward?
Yeah.
Hi, Alex.
Thanks for the question.
So something that we continue to learn about, continue to evaluate in regards to understanding, mechanistically the anemia and also potential mitigation strategies.
We've discussed this quite a bit in the past. In our previously reported clinical work, the anemia has been managed through various, means, including dose reductions, dose delays, erythrocyte stimulating agents.
We did conclude earlier this year that probably the ESA route is unlikely to help as much, as we might have liked. We continue to look at dose reductions, dose delays.
And once we look at the full data set across all of the solid tumor cohorts, I think we'll, be in a better position to comment a little bit later in the year.
Okay, great.
Thank you.
And then just a second question on business development.
You know, you've previously talked about remaining active in BD discussions.
You obviously have a number of partnerships that, you know, where you partner your technology.
I'm just wondering if you could speak to any interest in terms of, you know, looking at bringing in new technology externally or are you mostly focusing on, you know, partnering your technology to larger former players?
Thank you.
Yeah, so great question.
And I think a couple of different components to that question.
So first of all, you know, I would emphasize that the restructuring that we have announced recently, just reemphasize that that puts us in a robust cash position into 2025.
And that does not assume, you know, that guidance does not assume any additional business, development cash inflows or indeed any milestones for many existing deals that we have.
[music].
We do continue to be interested in leveraging the platform for additional business development, you know, in a strategic way.
[music].
