We are a clinical-stage biopharmaceutical company committed to bringing transformative bifunctional therapies to patients with solid tumors. We have built a platform designed to facilitate the development of bifunctional therapies that precisely target the tumor and deliver a tumor-modulating payload to the tumor site. This dual-targeting approach both enhances drug exposure within the tumor microenvironment, or TME, and limits systemic toxicity. This approach was deployed in the development of our lead program ficerafusp alfa, formerly BCA101, where we believe the bifunctional design can potentially improve upon the therapeutic profile of immunotherapies and targeted therapies by addressing resistance mechanisms and limiting off-target toxicity, therefore, enhancing the treatment effect and tolerability for targeted patient populations with cancer.

Our lead program ficerafusp alfa is a bifunctional antibody that combines two clinically validated targets, an epidermal growth factor receptor, or EGFR, directed monoclonal antibody with a domain that binds to human transforming growth factor beta, or TGF-β. Through this dual-targeting mechanism, ficerafusp alfa has the potential to exert potent anti-tumor activity by simultaneously blocking both cancer cell-intrinsic EGFR survival and proliferation, as well as the immunosuppressive TGF-β signaling within the TME. Ficerafusp alfa directs the TGF-β inhibitor into the immediate TME through the binding of EGFR on tumor cells, which we believe will lead to durable responses and an increase in overall survival, or OS, while reducing the adverse effects typically associated with systemic TGF-β inhibition.

We are a clinical-stage oncology company dedicated to unlocking a new paradigm in cancer therapeutics that addresses the significant unmet need in patients with oncogene amplified tumors by interrogating extrachromosomal DNA (ecDNA), a root cause of oncogene amplification observed in 14 to 17% of cancer patients. Our mission is to be the foremost biopharma company interrogating ecDNA biology to deliver transformative therapies that improve and extend the lives of patients with previously intractable oncogene amplified cancers.

ecDNA are large circular units of nuclear DNA that are a primary mechanism of gene amplification and are detected only in cancer cells, not in healthy cells. Despite tremendous advancements in treating cancer broadly, patients with oncogene amplified cancers generally derive little benefit from existing therapies, such as molecular targeted therapies or immunotherapies, and have worse survival rates than patients without oncogene amplification. Using our proprietary Spyglass platform, we identify targets essential for ecDNA functionality in oncogene amplified cancer cells, then design and develop small molecule drugs called ecDNA-directed therapeutic candidates (ecDTx) to inhibit those targets, with the aim to prevent cancer cells from using amplified oncogenes to grow, adapt, and become resistant to existing therapies.

Based on the preliminary clinical data generated to date, we believe that ficerafusp alfa in combination with pembrolizumab has the potential to become a first-line standard of care therapy in R/M HNSCC. In February 2025, we enrolled the first patients in FORTIFI-HN01, a pivotal Phase 2/3 trial (“FORTIFI-HN01 Phase 2/3 trial” or “FORTIFI-HN01”) of ficerafusp alfa in combination with pembrolizumab as a first-line therapy in R/M HNSCC excluding patients with oropharyngeal squamous cell carcinoma, or OPSCC, associated with human papillomavirus infection, or HPV-positive OPSCC patients.

Our lead ecDTx, BBI-355, is a novel, oral, selective inhibitor of checkpoint kinase 1 (CHK1), which manages replication stress associated with gene amplification in cancer cells. BBI-355 demonstrated CHK1 inhibition and tumor regressions in oncogene amplified preclinical cancer models, including those enabled by ecDNA, and is currently being studied in a first-in-human, Phase 1/2 clinical trial in patients with oncogene amplified cancers. We refer to this trial as POTENTIATE (Precision Oncology Trial Evaluating Novel Therapeutic Interrupting Amplifications Tied to ecDNA). We expect to have preliminary clinical proof of concept safety and antitumor activity data of BBI-355 in the second half of 2025. Our next program is directed at a previously undrugged kinesin target that we identified as essential for proper ecDNA segregation and inheritance during cancer cell division.

Ficerafusp alfa is a bifunctional antibody that combines the well-established biologies of two targets—the anti-EGFR antibody, cetuximab, fused to the extracellular domain of TGF-β receptor 2, or TGF-βRII. As indicated in Figure 4 below, ficerafusp alfa was designed to use EGFR-binding to deliver potent anti-TGF-β therapy directly to EGFR-expressing tumors, potentially removing circulating TGF-β and neutralizing its signaling activity using a strategy known as a “ligand trap”. We believe that localized TGF-β inhibition within the TME has the potential to increase its anti-tumor efficacy and durability, while limiting systemic toxicity. We also deliberately chose EGFR as the tumor-targeting antigen for a TGF-β ligand trap given academic literature supports potential synergistic mechanisms of TGF-β blockade and EGFR signaling inhibition.
