CytomX Therapeutics, Inc. (NASDAQ:CTMX) Q1 2024 Earnings Call Transcript May 8, 2024

CytomX Therapeutics, Inc. beats earnings expectations. Reported EPS is $0.1669, expectations were $-0.03. CytomX Therapeutics, Inc. isn’t one of the 30 most popular stocks among hedge funds at the end of the third quarter (see the details here).

Operator: Good day, and thank you for standing by. Welcome to the CytomX Therapeutics First Quarter 2024 Financial Results Conference Call. At this time, all participants are in a listen only-mode. After the speaker's presentation there will be a question-and-answer session. [Operator Instructions] Please be advised that, today's conference is being recorded. I would now like to turn the conference over to your speaker today, Chris Ogden, CytomX's Senior Vice President, Finance and Accounting. Please go ahead.

Chris Ogden: Thank you. Good afternoon and thank you for joining us. Before we begin, I would 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. We undertake no obligation to update any forward-looking statements, whether as a result of new information, future developments or otherwise. Earlier this afternoon, we issued a press release that includes a summary of our first quarter 2024 financial results and highlights recent progress at CytomX.

We also issued a press release today announcing positive initial Phase 1a dose escalation data for monotherapy CX-904 which will be the primary focus of today's call. We encourage everyone to read today's press releases and the associated materials, which have been filed with the SEC. Additionally, the press release, a recording of this call and our SEC filings can be found under the Investors and News section of our website. With me on the call today is Dr. Sean McCarthy, CytomX’s Chief Executive Officer and Chairman; Dr. Wayne Chu, CytomX's Chief Medical Officer. Sean will provide an update on the overall pipeline and also outline CytomX's broader strategy for mast T-cell engagers. Wayne will then give an update on the CX-904 Phase 1 dose escalation study before Sean provides closing comments and we open up the call for Q&A.

With that, I'll now turn the call over to Sean.

Sean McCarthy: Thanks, Chris, and good afternoon, everyone. It's a pleasure to be here today to share considerable progress during Q1, including our initial findings from our Phase 1 study of our EGFR targeted PROBODY T-cell engager CX-904. CytomX is highly focused on addressing major unmet needs in oncology using our PROBODY therapeutic platform, a proprietary antibody masking strategy designed to improve the therapeutic window for multiple antibody modalities through tumor localized activation. We are leveraging our PROBODY therapeutic platform to discover and develop new cancer therapies based on masked T-cell engagers, masked ADCs, and masked cytokines. Our broad and deep pipeline encompasses more than 15 active programs, including three clinical stage molecules and significant retained commercial rights.

Strategic partnering is a long standing components of our corporate strategy, and we're proud to be working closely with Bristol Myers Squibb, Amgen, Astellas, Regeneron, and Moderna on multiple PROBODY Therapeutic Programs. We continue to be in a strong financial position with $150 million of cash at the end of Q1, which provides cash runway to the end of 2025, not including any milestone payments under our existing collaborations or any potential new partnership funding. CytomX is very strong organizationally with integrated R&D capabilities, continued investment in our core technology, and a deeply experienced team dedicated to our vision of transforming lives with safer, more effective therapies. Moving to Slide 6, the CytomX product design strategy using our PROBODY Therapeutic platform is informed by more than a decade of experience and seeks to balance target selection, masking strategy and effective function to make meaningful impact in key areas of unmet need in oncology.

CX-904 brings the EGFR target together with T-cell engagement via CD3 with the goal of T-cell mediated killing of EGFR positive tumor types, potentially including those for which conventional antibodies have not shown activity. CX-2051 is our masked conditionally activated ADC that integrates the high potential of EpCAM as a cancer cell target with the potency of a topo-1 inhibitor payload ideally suited we believe to high EpCAM expressing tumors like colorectal cancer. CX-801 leverages the potent activity of the cytokine interferon alpha, which in this case is the effective mechanism itself. Our marked interferon is designed to locally activate the anti-tumor immune microenvironment with potential to drive responses across multiple cancer types, including melanoma, renal cell carcinoma and head and neck squamous cell carcinoma.

Q1 was an extremely productive quarter for CytomX. We are executing to our plans, and we're making progress across the full breadth of our pipeline. Today, we're announcing positive initial Phase 1a dose escalation data for monotherapy CX-904, our EGFR CD3 T-cell engager in solid tumors, and this is the main topic of our update here today. In addition to our exciting progress with CX-904, during Q1, the first dose cohort cleared in the Phase 1 clinical study of 2051, our ADC targeting EpCAM. This study is focused largely in colorectal cancer. And we anticipate initial data in the first half of 2025. Also during Q1, Phase 1 study initiation activities continued for CX-801, our masked interferon alpha, including the execution of an agreement with Merck to supply KEYTRUDA for combination with CX-801, and we announced that agreement last night.

Initial data from the 801 program is also anticipated in 2025. We continue to make excellent progress across our collaborations, including earning $10 million of milestones under our T-cell engaging bispecific collaboration with Astellas that was to preclinical progress on the first two programs in the alliance. We're also delighted to welcome Dr. Zhen Su to our board during Q1. So, a really productive start to 2024 for CytomX on all fronts and our current clinical pipeline is really gaining momentum and we have a very exciting 12 to 24 months ahead of us. Moving now to our T-cell engager strategy, T-cell engaging bispecific antibodies, of course, have enormous potential for the treatment of cancer and first demonstrated meaningful clinical benefit in hematologic malignancies.

Looking at the solid tumor landscape for T-cell engagers, however, it's taken time to see meaningful clinical progress. And for this modality to really breakthrough in solid tumors, there are some significant challenges to overcome. Notably, T-cell engagers bring very high potency and this potency can lead to toxicities in normal tissues, where the tumor antigen of interest may also be present. Another key limitation for T-cell engagers in solid tumors is cytokine release syndrome, resulting from systemic binding to CD3 on T-cells and also neurotoxicity in the form of ICANS. At CytomX, we have a broad based program focused on masking T-cell engagers to decrease tumor adjuvant binding in normal tissues and also decrease CD3 binding in the periphery, thereby improving therapeutic index.

In addition to our internal programs, we're working with partners Amgen, Astellas, Regeneron, and BMS in this exciting space. CX-904 is our lead program in the T-cell engager area, and I'd like to spend a few minutes now walking through the history and structure of this molecule. We've had a longstanding interest in EGFR CytomX, our seminal publication of the first ever successful antibody masking was focused on the EGFR binding antibody cetuximab, for which we showed a marked reduction in systemic skin rash for the masked antibody compared to the unmasked version. These findings set the stage for the evolution of the monospecific EGFR PROBODY into our CX-904 bispecific T-cell engager. We've reasoned that EGFR as a target has so much more potential to be realized and the realization of this potential would require a more potent effect of mechanism leading us to the concept of the mass EGFR CD3 strategy encompassed in CX-904.

We did actually publish an early lead molecule from this program in cancer research to demonstrate preclinical proof-of-concept, and we subsequently refined the structure using the depth of our platform and in collaboration with our partner Amgen. The next slide shows the molecular architecture of 904. CX-904 has one CD3 binding domain and one EGFR binding domain. Both domains are masked with unique peptides. Furthermore, the protease clinical substrates are different in each binding domain, reflecting our preclinical fine tuning strategy for optimization of therapeutic window. CX-904 also has an Fc region and so it would be expected to have an antibody like half life. This overall structure is somewhat similar to Amgen's Tarlatamab that has shown impressive results in small cell lung cancer.

Shown on the right of this slide is a recap of the therapeutic concept for CX-904 and for our platform generally. The concept is that masking reduces drug binding to target in normal tissues, whereas in tumor tissue, the masks are removed by activated tumor proteases. This tumor localization leads to the improvement or creation of a therapeutic window. For the EGFR CD3 antigen pair, it's been shown previously that the unmarked bispecific is highly toxic in preclinical models. So, our marketing strategy is, we believe, essential for creating a therapeutic window. In terms of the toxicities we're looking to mitigate, EGFR antibodies are well known to cause rash and gastrointestinal side effects. And so, we've been specifically looking out for our marketing strategy to really limit serious EGFR toxicities, particularly Grade 3 and above.

With regard to CD3, our marketing strategy is of course designed to limit CRS and ICANS. Before handing over to Wayne, let me review the high-level goals and achievements to date for our Phase 1 study of CX-904. Given the really high potency of T-cell engagers and the widespread expression of EGFR, goal number one for this study has been to evaluate the safety of 904, and we've made excellent progress as you will see from Wayne's presentation. We've explored non-step and step dosing. We were very pleased to see very limited CRS with non-step dosing, we believe because of successful CD3 masking. And in step dosing cohorts, rather remarkably, we've seen no CRS at all. We've also seen no evidence of ICANS at any dose level or schedule. Furthermore, while we have seen some EGFR toxicities, these have been manageable and have not limited us in achieving therapeutically active doses.

Again, this shows the success we believe of our EGFR marking strategy, and this success of EGFR marking is consistent with our prior published work that I mentioned earlier. Goal number 2 of our Phase 1 study has, of course, been to look for initial signs of anti-tumor activity. As we've said in recent months, any evidence of tumor stabilization or tumor shrinkage in this first in human study will be very encouraging. I want to emphasize that the patient population we've enrolled to date in this Phase 1 study is heavily pretreated and is a range of tumor types and is unselected for EGFR. All that said, we're delighted to announce today very encouraging early signs of anticancer activity for 904, including confirmed resist responses in pancreatic cancer, a very difficult to treat tumor type that is not typically responsive to EGFR inhibition or for that matter to immunotherapy.

Moreover, our initial assessments of pharmacodynamics are supportive of the mechanism of action of CX-904 as a mask T-cell engager, providing crucial platform proof-of-concept with read through, we believe, to the many other programs we're working on at CytomX. Importantly, this Phase 1 study is ongoing. We're continuing to dose escalate and enroll multiple tumor types, but our next goal is to determine recommended Phase 2 dose and to define plans for Phase 1b expansions. We see the data that we're sharing today as a very promising initial step in the development of CX-904, and this work positions CytomX at the forefront of the T-cell engager field. Now, let me hand over to Wayne to review the data in some detail.

Wayne Chu : Thanks Sean, and thanks everyone for the opportunity to share our early clinical and translational observations in the ongoing dose escalation study. This slide summarizes the dose escalation scheme, key eligibility criteria, and study objectives. Patients with tumors with known EGFR expression were enrolled. However, patients were not selected based on EGFR expression. Dose escalation was initiated using a non-step dosing schedule in which CX-904 was dosed once every two weeks. Doses starting from 7 micrograms through 6 milligrams were tested. As we will discuss in the subsequent slides, dose escalation of CX-904 continued using a step dosing schedule with an initial target dose of 5 milligrams. Various step dosing schedules were tested, after which the target dose was administered every two weeks.

The data presented today represents safety and efficacy data from a total of 13 dose escalation cohorts through the 10 milligram target dose. And as Sean mentioned, dose escalation continues with the current enrollment testing, the 15 milligram target dose. Selected baseline characteristics for enrolled patients are shown in this slide. The majority of patients enrolled in non-step dosing escalation cohorts were those with microsatellite stable or MSS colorectal cancer, which I will perm CRC from here on out, which has been demonstrated to be unresponsive to immune therapies, such as in checkpoint inhibitors. With step dosing escalation cohorts, we have begun to focus on patients with tumors with early evidence of clinical activity as well as other tumor types with known EGFR expression.

As is typical for a Phase I first in human dose escalation study, patients had advanced late line disease. Enrolled patients received a median of four prior cancer therapies, many were refractory to their last prior therapy, and a considerable proportion received prior EGFR and or PD-1 and PD-L1 directed therapy. Early clinical pharmacokinetic data from the non-step dosing schedule was consistent with the CX-904 PROBODY T-cell engager design. The graph on the left shows that total CX-904 exposure increases linearly with increasing dose, indicating no apparent change in dose dependent clearance or evidence of target mediated drug disposition. The graph on the right shows the cycle 1 PK profile of CX-904 at the 3 milligram dose level. The three curves show circulating analyte concentrations of intact or masked CD3, intact EGFR and total PROBODY.

Notably, the three curves are essentially superimposable, indicating that CX-904 exists in circulation in predominantly intact or matched form. Preliminary estimates of CX-904 half life are between 2.8 to 5.3 days. This slide summarizes treatment related adverse events observed with CX-904 in the non-step dosing schedule. It is important to mention that during the CX-904 escalation, no corticosteroids or other prophylactic medication was administered for systemic toxicity such as CRS and ICANS. The safety and tolerability data shown here with non-step dosing, therefore, reflect the ability of the masking to mitigate CRS in ICANS. With that, the virtual absence of CRS in ICANS is quite striking. Through the 3 milligram dose level, no CRS or ICANS of any grade were observed.

Even at the 6 milligram dose level, where two patients had dopamine toxicity of grade 3 tinnocinibitis and grade 3 rash, no patients experienced eye cancer of any grade and only grade 1 CRS characterized by transient fever without any other signs or symptoms associated with CRS was observed. Low grade musculoskeletal adverse events, such as arthralgia and arthritis were observed in addition to the one grade 3 tinnocinibitis at the 6 milligram dose level. Musculoskeletal events overall appear to be associated with a dose dependent increase in circulating IL-6 as shown in the graph. This is in direct contrast with CRS, where the association with circulating IL-6 levels was much less evident. Similarly, except for the Grade 3 rash observed at the 6 milligram dose level, only Grade 1 rash was observed.

Overall, the data presented here quite convincingly demonstrate the benefit of masking on effectively eliminating CRS and ICANS, which constitute dose limiting toxicities with many T-cell engagers. Based on the observations during dose escalation on the non-step dosing schedule, which demonstrated that CRS and ICANS are effectively mitigated by the masking of CX-904, step dosing schedules and tocilizumab prophylaxis were used specifically to mitigate emerging musculoskeletal adverse events, maintain a broad therapeutic index, and allow continuation of escalation to higher and potentially more efficacious target doses. These measures enabled escalation to higher CX-904 target doses while continuing to maintain an acceptable safety and tolerability profile.

Impressively, no CRS or ICANS of any grade was observed. Moreover, the incidence and severity of musculoskeletal adverse events did not substantially increase with higher CX-904 target doses, no related grade 3 rashes were reported, and no treatment related adverse events resulted in CX-904 treatment discontinuation. Overall, the safety profile of CX-904 continues to be favorable and importantly enable CX-904 administration and management of adverse events in an outpatient setting. In this regard, per protocol, no mandatory hospitalization is required for monitoring at clear dose levels, and the safety profile observed to date has not necessitated a change to this practice. In the context of a favorable safety profile, we observed compelling signs of CX-904 anti-tumor activity highlighted by activity observed to date in patients with advanced pancreatic adenocarcinoma.

The responses observed with CX-904 are highly encouraging given that outcomes in patients with recurrent metastatic pancreatic cancer remain extremely poor with current available therapies. Shown here is the waterfall plot of six efficacy evaluable patients treated across a range of target doses on both non-step and step dosing schedules. Confirmed partial responses per RECIST 1.1 criteria were observed in 2 of the 6 patients. One was treated with 6 milligrams on a non-step dosing schedule and had an 83% reduction in measurable tumor burden and a second patient was treated on a step dosing schedule with a target dose of 5 milligrams and had a 51% reduction in tumor burden. Furthermore, of note, all 6 patients had disease control. Of the 6 patients, 2 remain on study treatment and we will now discuss these patients in greater detail.

The first case describes a confirmed partial response in a 49-year old patient with metastatic pancreatic adenocarcinoma. Prior therapies included surgery, radiation therapy, and three lines of prior chemotherapy. The patient received CX-904 on a step dosing schedule with 1.5 milligrams administered on day one and the target dose of 5 milligrams administered one week later and then two weeks thereafter every two weeks thereafter. The patient did not experience cytokine relief syndrome or ICANS. The patient experienced Grade 3 related arthralgia, but this resolved to Grade 1 after a one cycle delay in administration of corticosteroids. As shown in the CT scan images, the patient achieved a partial response with deeper reduction in tumor burden observed at the confirmatory CT scan.

And as I mentioned, this patient remains on CX-904 treatment, having received over three months of treatment to date. This next case illustrates durable, stable disease with CX-904 in a 59-year old patient with metastatic pancreatic adenocarcinoma who had received three prior lines of systemic chemotherapy. The patient received CX-904 on a step dosing schedule with 1.5 milligrams administered on day 1, 5 milligrams on day 8, and 10 milligrams on day 15 every two weeks thereafter. The patient tolerated CX-904 treatment well with no CRS, ICANS, or musculoskeletal events and only grade 1 papulopustular rash, which resolved with topical treatment. The patient was able to maintain stable disease with no evidence of measurable tumor growth and additional information supporting continued clinical benefit included a greater than 50% reduction in serum CA19 levels and overall improvement of performance status from baseline.

This patient remains on CX-904 treatment, having received over 3.5 months of treatment to date. Preliminary translational data indicates T-cell pharmacodynamic activity that is consistent with the mechanism of action of CX-904 in pancreatic adenocarcinoma. The figure on the left is an immunofluorescence image from a biopsy obtained prior to CX-904 treatment in a patient with pancreatic cancer who achieved a deep partial response. The colors indicate T-cell markers in red, dark blue, and magenta and cancer cells in light blue. And as you can see, the pretreatment biopsy showed a high level of CD8 positive T-cells within the tumor microenvironment, indicating their contribution to T-cell engager anti-tumor activity. The figure on the right shows the reduction of peripheral CDA positive T-cells as it relates to RESIST-1.1 response.

Both pancreatic patients with confirmed partial response had among the greatest reduction of peripheral CD8 positive T-cells following CX-904 treatment, consistent with the trafficking of T-cells from the periphery to tumor site as a mechanism of action of T-cell engagers. Taking a step back from the early but compelling activity of CX-904 patients with pancreatic adenocarcinoma, shown here is the waterfall plot for efficacy evaluable patients treated with CX-904 at target doses greater than or equal to 0.75 milligrams. While no objective responses were observed in patients with other tumor types, reductions in measurable disease burden were observed in a total of 8 patients, including the 2 pancreatic cancer patients with partial responses.

Reductions in measurable disease burden were also observed in patients with CRC, esophageal carcinoma, and non-small cell lung cancer. We believe that the early signals of CX-904 activity in pancreatic cancer are compelling and that currently tested target doses are efficacious. As a result, study enrollment moving forward, in addition to continuing to enroll patients with pancreatic cancer, will focus on patients with other EGFR positive tumor types, including lung cancer, upper GI cancers, and head and neck cancers. This slide summarizes the time on study treatment for patients treated with CX-904, again highlighting the patients with pancreatic adenocarcinoma that continue to derive clinical benefit with ongoing CX-904 treatment. Importantly, while CX-904 has had minimal clinical activity to date in patients with CRC, CX-904 retains its pharmacodynamic activity as illustrated in this slide, which are immunofluorescence images of biopsies taken from a patient with MSS CRC at baseline and while on CX-904 treatment.

As you can clearly see at baseline, the tumor's tumor is notable for the almost complete absence of CD8 positive T-cells within the tumor. In contrast, the on treatment biopsy showed a substantial increase in the number of CD8 positive T-cells within the tumor. This observation is a clear demonstration of the CX-904 mechanism of action and demonstrates potential combination strategies for the treatment of CRC. In summary, we are very encouraged by this early clinical data of CX-904 in the ongoing Phase 1 dose escalation. CX-904 has a favorable safety profile, which given the broad expression of EGFR in normal tissues in addition to cancers, is indicative of the ability of masking to maintain a meaningful therapeutic index. Second, CX-904 has promising early efficacy in pharmacodynamic activity, highlighted by the confirmed partial responses in patients with metastatic pancreatic adenocarcinoma and early demonstration of CX-904 mechanism of action, including in colorectal cancer.

The clinical and translational observations have been extremely valuable in demonstrating not only the early clinical activity of CX-904, but also provide clear direction to plans to ultimately determine the recommended Phase 2 dose. And this includes continued enrollment in pancreatic cancer and enrollment in other EGFR positive tumor types that are also more responsive to immune therapies based on prior clinical experience. Together, these data will inform future development of CX-904, which include considerations of combination strategies. And with that, I will now turn it back to Sean for concluding remarks.

Sean McCarthy: Great. Thanks, Wayne. So staying with CX-904 for a moment, we're excited by our progress to date developing this very novel drug candidate. EGFR is such a high potential target with expression on many tumor types, and we're just at the beginning of learning what CX-904 can do for patients. We clearly have a drug candidate with confirmed monotherapy activity, and we're redoubling our efforts to generate data in additional tumor types as we more broadly explore 904. Our data also unlocks potential strategies for future combinations, as Wayne mentioned. Focusing for a moment on pancreatic cancer, this is one of the greatest areas of unmet need oncology today, and it's notoriously difficult to treat. Second line response rates were in the single digits and PFS and overall survival in just a matter of months.

To reiterate the importance of our data shared today, pancreatic cancer does not respond to either anti-EGFR antibodies or to immunotherapy alone. What we have shown today is that when we combine these two powerful strategies in bispecific form, enabled by our PROBODY masking technology, we can elicit meaningful responses in late stage pancreatic cancer patients. CX-904 brings these two mechanisms together into an integrated and unique pharmacology that could impact this very difficult to treat disease, showing how masked PROBODY T-cell engagers can be a new frontier in the war on cancer. These results are the embodiment of exactly what CX-904 was designed to do, and we plan to aggressively pursue this signal for the benefit of people afflicted with this devastating tumor type.

Now zooming back out to our full pipeline and looking ahead to the rest of this year and also into 2025, we anticipate a great deal of additional progress at CytomX. We see the data we're sharing today on 904 as a promising initial step in developing this asset and also our T-cell engager portfolio overall. T-cell engagers are starting to break through in solid cancers and it's exciting to be playing our part here at CytomX in this highly promising field, not only with 904, but also the many T-cell engager programs we're advancing through preclinical discovery and development. And we look forward to providing an additional CX-904 update later this year. Now, of course, today's update has been very 904 focused, but before I wrap up, I'd like to remind everyone to also keep our other programs in mind.

We're making a lot of progress on multiple fronts. CX-2051 and CX-801 are wholly owned assets, and we anticipate Phase 1a data for both in 2025. We're already in our second Phase 1 cohort with 2501, our masked anti-EpCAM ADC clinical initiation for CX-801, our masked interferon, is imminent. I'd like to close by thanking everyone involved in this work for their commitment to our vision. The CytomX team is intensely focused on delivering an innovative pipeline for the benefit of people living with cancer, and it's truly a privilege to work with such a talented team. I also want to sincerely thank the patients who joined our studies, their families, and our investigators. And with that, operator, let's go ahead and open up the call for questions.

Operator: [Operator Instructions] And for your first question, it comes from the line of Peter Lawson from Barclays. Please go ahead.

lol, InvestAmerica, don't know how or why they could be UPBEAT and not even mention that over 100% gain from 4ish to 9.55 and then the crushing blow, down over 100% (thought that wasn't possible) to 50% below the original 4ish dollars...BRUTAL...and no comment 🤐 from anyone @ CTMX? Odd...

I guess these "FREE SHARES" have to be digested along with any additional "SHORT SHARES" from 9.55 down all the way to 1.91...As of May 6, 2024, the registrant had 77,919,369 shares of common stock, $0.00001 par value per share, outstanding. This number does not include 6,923,077 shares of common stock issuable upon the exercise of pre-funded warrants outstanding as of May 6, 2024 (which are immediately exercisable at an exercise price of $0.00001 per share of common stock, subject to beneficial ownership limitations) sold in the registrant’s private placement in July 2023.From the 10-Q. 6.9 million shares for 69 bucks.
7M shares x avg sell price of $8 = $56 million...

Did these shorts cover? Yet?



Nowhere to go but UP? This could bottom and pOp...JMO...have to see if that 17¢ EPS was a one-time-event...revenue doubled...

But all joking aside, Dude, all that MERCK news too --- of the 7th & 8th this week --- ALSO did absolutely NOTHING to stop CTMX's price calamity!! However, its lowest PRICE has just now been determined --- see live film-clip, below, near a mid-Atlantic hydrothermal vent 'smoker'!! (The VOICE-OVERS on the video are by CTMX's own CEO & Chief Financial Officer, who both seem curiously upbeat, nevertheless!!)

Or did all the officers get killed in a plane crash, Boeing of course...?
There is no history or word that I've heard of this stock's launch and crash in afterhours yesterday...no news, nada, nothing. Almost like afterhours didn't even happen.
Why did it crash? EPS of 17c for the quarter...almost bought around $8...looking to buy...maybe...

Bought shares as low as $2.20 after the pump and then the massive sell off,seemed like if the whole thing was planned by some manipulating insiders who probably were shorting the after hours highs if they were able borrow them.

CTMX: Indeed, King Dino!! And don't forget, MERCK already has a stake in this Firm. Furthermore, although the ultimate CAUSES of the huge price swings in this stock today may never be known. However, nobody on iHub even mentioned today, nor yesterday, the 5-7-24 contractual agreement between CTMX and the 'Big Pharma' firm, MERCK. Myself, I don't think that the PRICE of CTMX will remain RED in color for very much longer.

$CTMX learned the hard way , lost money on many Phase I stocks

MY ADVICE IS ITS BEST TO JUST STAY AWAY FROM MOST PHASE I STOCKS ALL TOGETHER

this ones news sounds weak

https://www.globenewswire.com/news-release/2024/05/08/2878255/37704/en/CytomX-Therapeutics-Announces-Positive-Initial-Phase-1a-Dose-Escalation-Data-for-Monotherapy-CX-904-EGFRxCD3-PROBODY-T-Cell-Engager.html

dose escalation?

$CTMX its CX-904, T-cell engager, only works for pancreatic cancer? It appears not effective for CRC, gastric, esophageal, NSCLC, HNSCC, why? forget this one. Be long $JANX and $LVTX— Nick zheng (@pick1998_2) May 8, 2024

$CTMX Down 40%. You can celebrate two PRs though. 😂 https://t.co/OZLhxKdGrm— Alp Bugra Basat, MD (@AlpBugraBasat) May 8, 2024
