SAN DIEGO, March 25, 2021 /PRNewswire/ -- BioAtla, Inc., a global clinical-stage biotechnology company focused on the development of Conditionally Active Biologic (CAB) antibody therapeutics, today announced financial results for the full year 2020 and provided an update on its business.
"BioAtla made several achievements in 2020 that significantly enhance the company's ability to advance our CAB clinical programs, expand our development portfolio, and further exploit the opportunities of our CAB technology," stated Jay M. Short, Ph.D., chairman, chief executive officer and co-founder of BioAtla, Inc. "The encouraging clinical trial data that allows us to proceed into potentially registration-enabling Phase 2 clinical trials along with prospects of developing several CAB bispecific candidates underscore the potentially broad applicability of CAB technology to address a wide range of tumor types and other indications," added Scott Smith, president of BioAtla.
Advancing clinical trials for lead candidates BA3011, BA3021 and BA3071 We are developing BA3011, CAB-AXL-ADC, as a potential therapeutic for multiple solid tumors, including soft tissue and bone sarcoma, non-small cell lung cancer (NSCLC) and ovarian cancer with other potential indications in the future. We have completed a Phase 1 trial in patients with refractory solid tumors, established a recommended Phase 2 dose, and continue to dose patients that are responding to therapy.We recently initiated dosing in a potentially registration-enabling Phase 2 clinical trial in soft tissue and bone sarcoma. We have also initiated a Phase 2 clinical trial in PD-1 refractory NSCLC patients. Additionally, we expect a multi-center investigator-initiated trial in platinum-resistant ovarian cancer will likely commence in the first half of 2021.
We are developing our second product candidate BA3021, CAB-ROR2-ADC, a CAB antibody directed against ROR2, a receptor tyrosine kinase that is overexpressed across many different solid tumors including breast, lung, pancreatic, renal, colorectal, head and neck and melanoma. We are developing BA3021 as a potential therapeutic for multiple solid tumors, including NSCLC, ovarian cancer and melanoma. We have completed a Phase 1 all-comers dose-escalation trial with BA3021 where we observed two partial responses in advanced, treatment refractory NSCLC and one partial response in melanoma which represents all ROR2 positive patients at a Phase 2 relevant dose and ROR2 expression level. We believe BA3021 has broad potential as a cancer therapy for patients with advanced solid tumors. We recently initiated Phase 2 enrollment in patients with PD-1 refractory NSCLC and melanoma.
BA3071, is a CAB anti-CTLA-4 antibody that is being developed as an immuno-oncology agent with the goal of delivering the efficacy of approved CTLA-4 antibodies, such as ipilimumab, but with lower toxicities due to the CAB's tumor microenvironment-restricted activation. In a global collaboration with Beigene, we are developing BA3071 as a potential therapeutic for multiple solid tumor indications, including renal cell carcinoma, NSCLC, small cell lung cancer, hepatocellular carcinoma, melanoma, bladder cancer, gastric cancer and cervical cancer. BeiGene is responsible for all costs of development, manufacturing and commercialization globally. BioAtla is eligible to receive milestone payments and royalties on product sales upon regulatory approvals and commercialization by BeiGene. A Phase 1 dose-escalation trial of BA3071 as monotherapy and in combination with tislelizumab, an anti-PD-1 antibody in late stage development by BeiGene, are planned to commence in 2021.
Plans to advance development of several bispecific CAB candidates We have also leveraged our CAB technology to develop bispecific antibodies, which bind both a tumor-specific antigen and a T cell receptor using CAB antigen-binding domains. With this design, bispecific antibodies can induce potent T cell responses against tumors expressing the tumor target antigen in a simplified manner relative to even off-the-shelf or allogeneic CAR-T therapies. We have shown in preclinical experiments that our CAB bispecific molecules meet or exceed the activity of conventional bispecifics and reduce systemic activation of potentially fatal immune responses. We advanced two CAB bispecific antibody product candidates, EpCAM/CD3 and B7-H3/CD3, into IND-enabling studies in the second half of 2020. We are also evaluating ADC modalities for each of our CAB bispecific molecules, including EGFR/CD3 and Nectin-4/CD3. Our goal is to submit up to four US INDs in 2022 for our CAB bispecific or ADC molecules.
Recent peer-reviewed publication in Proceedings of the National Academy of Sciences (PNAS) indicates potentially broad application of BioAtla's CAB technology The paper describes the design and functionality of therapeutic antibody candidates utilizing BioAtla's proprietary CAB technology making them active only in the acidic tumor microenvironment while binding is reversibly inhibited in healthy tissue. This improved tumor targeting utilizes a newly discovered chemical switch system and is shown in animal models to provide for potent anti-tumor activity with markedly reduced toxicity to normal tissue, indicating a widened therapeutic index. BioAtla scientists discovered this novel chemical switch mechanism that involves physiological-occurring chemicals, such as bicarbonate and hydrogen sulfide. These molecules are negatively charged at physiological conditions and interact with positive charged areas on the protein surface. Under acidic conditions of the tumor microenvironment they are neutralized and released from the protein surface, uniquely allowing CAB antibodies to bind to their target and attack the tumor cell. BioAtla refers to this novel physiological mechanism, used for generating CABs, as Protein-associated Chemical Switch(es) or PaCS mechanism.
It is expected from the studies described in the paper that there is a potential for other yet to be identified PaCS molecules in disease related microenvironments, whether controlled through pH, concentration, or other molecular characteristics (intra- or intermolecularly) for enhancing a drug's therapeutic index. Potential new therapeutic candidates addressing these opportunities are not limited to antibodies, but also include small molecules, encompassing lipids, sugars and nucleic acid-based agents or drugs. Further, it is expected that PaCS protein-chemical systems are important naturally occurring regulatory systems linked to a range of disease-related microenvironments, including cancer, inflammation and cellular senescence.
Full year 2020 financial results Cash and cash equivalents as of December 31, 2020 were $238.6 million compared to $3.7 million as of December 31, 2019. In July 2020, BioAtla completed a successful private placement offering with institutional investors, for net proceeds of approximately $68.2 million. In December 2020, we received net proceeds of approximately $198.4 million from our initial public offering. We expect current cash and cash equivalents will be sufficient to fund planned operations at least through end of 2022.
Research and development (R&D) expenses were $19.9 million for the full year ended December 31, 2020 compared to $25.9 million for the year 2019. We expect our R&D expenses to increase substantially for the foreseeable future as we continue to invest in R&D activities to advance our product candidates, and our clinical programs and expand our product candidate pipeline.
General and administrative (G&A) expenses were $10.6 million for the full year ended December 31, 2020 compared to $7.5 million for the year 2019. We expect our G&A expenses to increase as a result of operating as a public company. In addition, we expect our intellectual property expenses to increase as we expand our intellectual property portfolio.
Net loss for the full year ended December 31, 2020 was $35.9 million compared to a net loss of $29.8 million for the year 2019.
