BioAtla (NASDAQ:BCAB) (NASDAQ: BCAB) is a clinical‐stage biotechnology company focused on the development of conditionally active biologics (CABs) for oncology and other serious diseases. Utilizing its proprietary CAB technology platform, BioAtla engineers monoclonal antibodies, bispecifics and antibody-drug conjugates that remain inactive in healthy tissues but become activated in the tumor microenvironment. This targeted approach aims to improve therapeutic index by enhancing anti‐tumor potency while minimizing off-target effects and systemic toxicity.

Founded in 2012 and headquartered in San Diego, California, BioAtla has advanced multiple product candidates into clinical trials. Lead programs include BA3011, a conditionally active antibody targeting cMet for solid tumors, and BA3071, a conditionally active T-cell–engaging bispecific targeting prostate‐specific membrane antigen (PSMA) in metastatic castration-resistant prostate cancer. The company’s research pipeline also features several discovery‐stage CAB molecules directed against tumor-associated antigens and immune checkpoints, reflecting its strategy to address high‐unmet‐need indications.

BioAtla serves a global patient population through internal research and development operations in the United States and China. The company’s R&D infrastructure integrates molecular engineering, translational biology and preclinical pharmacology, enabling rapid optimization of CAB candidates. In addition to its internal programs, BioAtla has entered into strategic collaborations and licensing agreements to accelerate development and broaden the therapeutic reach of its platform.

Led by President and Chief Executive Officer Christian S. Neal, BioAtla’s management team brings extensive experience in antibody engineering, clinical development and regulatory affairs. The company’s mission is to transform the safety and efficacy profile of biologic therapies by harnessing the precision of conditionally active molecules. As BioAtla advances its clinical portfolio, it aims to deliver innovative treatment options that improve patient outcomes and set new standards in targeted oncology therapy.

BioAtla Q3 2025 Earnings Call Transcript

Key Takeaways

• Positive Sentiment: FDA alignment secured on the Phase 3 registrational trial design for OSV in second-line+ OPSCC with dual primary endpoints (overall response rate and overall survival), enabling a pathway for accelerated approval and planned trial initiation early next year.
• Positive Sentiment: Management is in advanced stages of finalizing a strategic transaction with a potential partner by year-end, which could support development and commercialization plans.
• Positive Sentiment: Strong Phase 2 OSV data were highlighted — a 45% overall response rate and median overall survival of 11.6 months in late-line HPV+ OPSCC versus historical ORRs of 0–3.4% and median OS of ~4.4 months, supporting the registrational path.
• Positive Sentiment: CAB platform programs showed encouraging clinical signals: the dual CAB EpCAM T-cell engager demonstrated manageable safety and tumor reductions (including a confirmed PR and >6 months disease control), and mecbotamab vedotin (MCV) showed prolonged median OS (~21.5 months) in refractory soft tissue sarcoma cohorts.
• Negative Sentiment: Financial runway is constrained with $8.3 million in cash and cash equivalents as of Sept 30, 2025 (plus a subsequent $2 million milestone in October); net loss widened to $15.8 million for the quarter, raising funding and partnership reliance risk despite reduced R&D and G&A spending.

Presentation

[Operator]

Good day, everyone, and welcome to today's BioAtla Third Quarter 2025 Earnings Call. At this time, all participants are in a listen-only mode. Later, you may have the opportunity to ask questions during the question-and-answer session. I will be standing by should you need any assistance. It is now my pleasure to turn the conference over to Julie Miller with LifeSci Advisors. Please go ahead.

[Julie Miller, Head of Investor Relations at LifeSci Advisors]

Thank you, Operator. Good afternoon, everyone. With me today on the phone from BioAtla are Dr. Jay Short, Chairman, CEO, and co-founder; Dr. Eric Sievers, Chief Medical Officer; Sheri Lydick, Chief Commercial Officer; and Richard Waldron, Chief Financial Officer. Earlier this afternoon, BioAtla released financial results and a business update for the quarter ended September 30, 2025. A copy of the press release is available on the company's website. Before we begin, I'd like to remind everyone that statements made during this conference call will include forward-looking statements, including but not limited to statements regarding BioAtla's business plans and prospects, potential selective licensing, collaborations, and other strategic partnerships.

[Julie Miller, Head of Investor Relations at LifeSci Advisors]

The potential for our clinical trials to be registrational, results, conduct, progress, and timing of our research and development programs and clinical trials, expectations with respect to enrollment and dosing in our clinical trials, the anticipated clinical benefits, safety, efficacy, and market potential of our product candidates, plans and expectations regarding future data updates, clinical trials, regulatory meetings, and regulatory submissions, the potential regulatory approval path for our product candidates, expectations about the sufficiency of our cash and cash equivalents, and expected R&D and G&A expenses. These statements are based on current expectations and assumptions and are subject to various risks and uncertainties that can cause actual results to differ materially from those expressed or implied. These risks and uncertainties are described in our filings made with the SEC, including the most recent quarterly report on Form 10-Q and other subsequent filings.

[Julie Miller, Head of Investor Relations at LifeSci Advisors]

You are cautioned not to place undue reliance on these forward-looking statements, which speak only as of today, November 13, 2025. BioAtla disclaims any obligation to update or revise such statements to reflect new information, future events, or circumstances, except as required by law. With that, I'd like to turn the call over to Jay Short. Jay?

[Jay Short, Chairman & CEO at BioAtla]

Thank you, Julie. And thanks to everyone for joining us for our third quarter 2025 BioAtla earnings call. First and foremost, it is important to update that we are currently in advanced stages to finalize a strategic transaction with a potential partner by year-end. Further, in September, I'm pleased to report that we achieved FDA alignment on the phase III OSV registrational trial design, including dosing regimen, comparator arm, and approval endpoints for the treatment of second-line plus Oropharyngeal Squamous Cell Carcinoma, or OPSCC. OPSCC represents a sizable and steadily growing patient population poorly served by EGFR inhibitors and other standard-of-care regimens. Importantly, this randomized phase 3 trial will evaluate dual primary endpoints of overall response rate and overall survival. And this dual endpoint design provides the opportunity for achieving accelerated approval followed by full approval.

[Jay Short, Chairman & CEO at BioAtla]

We are currently preparing for initiation of the OSV phase III study and remain on track to advance this program. We also recently presented compelling data with multiple programs, including our dual CAB, EpCAM, TCE, or BA3182, and MCV, which further validates the potential of our CAB platform to deliver differentiated therapies for patients with difficult-to-treat cancers. In a few moments, Eric will provide an overview of these data. I'm also pleased to share that we achieved a development milestone under our license agreement with Context Therapeutics related to the dual CAB, NECTIN-4 TCE program. This milestone not only provides non-dilutive capital but also further validates the underlying biology and its impact on improving the therapeutic index of our CAB T-cell engager platform.

[Jay Short, Chairman & CEO at BioAtla]

We continue to be encouraged overall by our CAB T-cell engager results, including this milestone achievement as well as the promising interim data from BA3182 recently presented at ESMO. Finally, our MCV program continues to distinguish itself with the potential for increasing overall survival compared with approved treatments in soft tissue sarcoma recently presented at [CTOS]. These overall survival data are analogous to the prolonged overall survival data we observe in mutant KRAS non-small cell lung cancer patients. With that, I would now like to turn the call over to Sheri to provide an overview of the substantial market opportunity for OSV, our CAB ROR-280C. Sheri?

[Sheri Lydick, Chief Commercial Officer at BioAtla]

Thank you, Jay, and good afternoon, everyone. OSV has demonstrated compelling clinical activity in heavily pretreated patients with HPV-positive OPSCC, a population with a poor prognosis. OPSCC is a steadily growing indication primarily driven by prior HPV infection. Up to 80% of OPSCC cases in the U.S. are caused by HPV, and by 2030, OPSCC is projected to become the most common subtype of head and neck cancer in the U.S. The unmet need is significant, and current standards of care, including EGFR inhibitors, provide minimal benefit in this setting. This epidemiology underscores the urgency of advancing new therapies. From a commercial perspective, the opportunity is significant. We estimate worldwide peak sales of OSV to be approximately $800 million in second-line and later OPSCC alone. The total worldwide OPSCC market is projected to reach $3 billion by 2032.

[Sheri Lydick, Chief Commercial Officer at BioAtla]

When you consider the broader HPV-positive solid tumor market, including cervical cancer, the value exceeds $7 billion globally. We continue preparations for enabling initiation of the phase III study with the goal of advancing the study with a strategic partner early next year. With that, I would now like to turn the call over to Eric for additional clinical and program updates. Eric?

[Eric Sievers, CMO at BioAtla]

Thank you, Sheri. Phase 3 trial preparations for OSV continue as we achieved alignment on the phase III registrational trial design with the potential for accelerated approval followed by full approval with its dual endpoint design. Importantly, OSV offers a differentiated profile in HPV-positive OPSCC as overexpression of the ROR-2, the target of the ADC, is driven by oncoproteins associated with HPV infection forming a cancer axis that is associated with poor prognosis and resistance to chemo and immunotherapies. We have seen OSV's potential with our strong phase II data in late-line patients demonstrating an overall response rate of 45% and a median overall survival of 11.6 months compared to the historical response rates of only 0%-3.4% and median overall survival of only 4.4 months with standard therapies. Beyond OSV, we continue to make exciting progress with our dual CAB, EpCAM, T-cell engager.

[Eric Sievers, CMO at BioAtla]

EpCAM is broadly expressed across adenocarcinomas of the colon, stomach, pancreas, biliary tract, lung, breast, prostate, and thyroid, making it a compelling bispecific T-cell engager target. However, EpCAM is also broadly expressed on healthy epithelial tissues, and this broad expression is associated with on-target, off-tumor toxicities when targeted by traditional antibodies. We believe we have a notable advantage with our dual CAB, EpCAM, T-cell engager as it is designed to selectively bind within the acidic tumor microenvironment and eliminate on-target, off-tumor toxicity. We recently presented preliminary data from our phase I trial with our dual CAB, EpCAM, T-cell engager in advanced adenocarcinomas at the annual 2025 European Society for Medical Oncology Congress. Overall, data indicate that the safety profile is manageable.

[Eric Sievers, CMO at BioAtla]

In addition, we are continuing to see encouraging preliminary signs of tumor reductions across a broad range of indications and notable prolonged tumor control with a confirmed partial response at the 0.6 milligram dose. This responding patient with intrahepatic cholangiocarcinoma, a particularly challenging cancer of the biliary tract, remains on treatment without progression now for more than six months. We also remain encouraged by the performance of mecbotamab vedotin, or MCV. Data from our phase 2 trial of MCV alone and in combination with nivolumab in patients with treatment-refractory soft tissue sarcomas were recently presented at the Society for Immunotherapy of Cancer annual meeting. Data from 44 evaluable patients with leiomyosarcoma, liposarcoma, and undifferentiated pleomorphic sarcoma showed median overall survival of 21.5 months compared to median overall survivals of only 11.5-13.6 months reported for approved agents in similar advanced soft tissue sarcoma populations.

[Eric Sievers, CMO at BioAtla]

Further, these overall survival observations are directionally consistent with prior experience in mutated KRAS non-small cell lung cancer from our other ongoing phase II trial of MCV and support its potential utility as a treatment for solid tumors. The safety profile of MCV as a monotherapy and in combination with an anti-PD-1 antibody was manageable and is consistent with conditional binding of the AXL target restricted to the tumor microenvironment. No new safety signals were identified. I shall now hand it over to Rick to review the third quarter 2025 financials. Rick?

[Richard Waldron, CFO at BioAtla]

Thank you, Eric. As of September 30, 2025, we had $8.3 million in cash and cash equivalents. In October 2025, Context Therapeutics triggered a $2 million milestone payment to us under the license agreement for the dual CAB, NECTIN-4 TCE. The payment was received recently and reflects continued progress and validation of BioAtla's differentiated T-cell engager platform. Of note, our third quarter cash and cash equivalents do not include this payment or any R&D funding from the collaboration. For the third quarter ended September 30, 2025, we reported a net loss of $15.8 million compared to a net loss of $10.6 million in the same quarter of 2024, which included $11 million in collaboration revenue from our license with Context Therapeutics.

[Richard Waldron, CFO at BioAtla]

The increase in net loss was primarily due to the collaboration revenue recorded in 2024 and a $2.1 million non-cash loss on warrant liability recorded in the third quarter of 2025 related to warrants issued in the December 2024 financing, offset by decreases in R&D and G&A expense. Research and development, or R&D expenses, were $9.5 million for the quarter ended September 30, 2025, compared to $16.4 million for the same quarter in 2024. The $6.9 million decrease was primarily driven by reduced program development costs due to prioritization of clinical programs, low headcount-related expenses following the workforce reduction announced in March 2025, and lower non-cash stock-based compensation. We continue to expect R&D expenses to decline through the remainder of 2025 as we continue to concentrate resources on our prioritized programs.

[Richard Waldron, CFO at BioAtla]

General and administrative, or G&A expenses, were $4.2 million for the quarter ended September 30, 2025, compared to $5.9 million for the same quarter in 2024. The $1.7 million decrease was primarily attributable to reduced personnel costs related to the workforce reduction in March 2025 and lower stock-based compensation expense. Now, back to Jay.

[Jay Short, Chairman & CEO at BioAtla]

Thank you, Rick, and thank you all for joining us today. As we look ahead, BioAtla is entering an exciting phase. Now, with FDA alignment on our phase III trial design for OPSCC, we are poised to begin enrolling our registrational phase 3 trial early next year. This program not only addresses a critical unmet need in oncology but also represents a substantial commercial opportunity. In addition, we believe our dual CAB, EpCAM, TCE program represents one of the broadest pan-cancer opportunities since PD-1, with the potential to treat over 1 million adenocarcinoma cancer patients per year in high unmet need areas. Not surprisingly, the potential of this program is attracting numerous early discussions with both investors and potential future partners. We expect a key clinical trial readout in the first half of next year, with several important events related to this program throughout 2026.

[Jay Short, Chairman & CEO at BioAtla]

Finally, we remain focused on our prioritized programs for delivering meaningful therapies to patients and value to shareholders. We appreciate your support and look forward to sharing further updates in the exciting months ahead. With that, we will turn it back to the operator to take your questions.

[Operator]

At this time, if you would like to ask a question, please press the star and one on your telephone keypad. You may withdraw yourself from the queue at any time by pressing star two. Again, for your questions, that is star and one. We'll pause a moment to allow any questions to queue. Once again, that is star and one. We'll take our first question from Arthur Hay, with CU. Line is open.

[Arthur Hay, Analyst]

Hey, good afternoon, Jay and team. Thanks for taking my question. Maybe for Eric, for the ROR-2 program, the phase III study design-wise, could you give us more color around what's the patient number side by the agency to getting accelerated approval readout there? Also, for the control arm, is there any stratification according to different treatments the patient could receive?

[Eric Sievers, CMO at BioAtla]

Thank you, Arthur. Your first question is about what would be the number of patients for an accelerated approval. I want to refer everyone to slide 42 on our corporate deck, where we discuss the phase 2 meeting key outcomes. Here, we talk about the pivotal trial design, where for full approval, we're looking at approximately 300 patients that are prospectively randomized and stratified. For accelerated approval, it would be an interim analysis roughly about the time of the full enrollment of patients, but obviously, that look would be much earlier. Your second question is about stratification factors for the two arms. We haven't disclosed that, but P16 would be one of them, and then it would have to do with local regional disease, yes or no.

[Eric Sievers, CMO at BioAtla]

Stratification factors are to ensure that there's equal distribution of patients based on important prognostic factors across the two arms.

[Arthur Hay, Analyst]

Thanks, Eric. Maybe for the 3182, could you tell us a little bit more what kind of data we could expect from next year, the readout-wise?

[Eric Sievers, CMO at BioAtla]

Sure. As you know from the ESMO dataset, we presented 35 patients, all receiving subcutaneous dosing, and then a pretty fulsome accounting of the patients and their experience in slide 23, which is the swimmer's plot showing the confirmed partial response and where we are in the dose escalation. For the next data output, we would anticipate it would be in the first half of next year, and we would be reporting pretty comprehensively on the additional dose and schedule evaluations that we'll be doing over the course of the next few months to try to provide a really fulsome accounting of the experience altogether. Jay, did you want to add anything?

[Jay Short, Chairman & CEO at BioAtla]

No, I think that captures it, Eric. I do not really have anything to add on that. I think certainly, I think we will be able to meet the timeline of being in the first half.

[Arthur Hay, Analyst]

Okay. Awesome. Thanks, Jay, and congrats on the progress.

[Jay Short, Chairman & CEO at BioAtla]

Yeah. Thank you, Arthur.

[Operator]

Once more, for your questions, that is star and one. We'll pause just a moment. It does appear that there are no further questions at this time. I would now like to turn the call back to Jay Short for any additional or closing remarks.

[Jay Short, Chairman & CEO at BioAtla]

I'd just like to say I think it's a very exciting time for the company, and we're very much looking forward to the key readouts that are just around the corner. Thank you for your continued support and for listening today. Bye-bye.

[Operator]

This does conclude today's program. Thank you for your participation. You may disconnect at any time and have a wonderful rest of your day.
