About Becotatug Vedotin MEIYOUHENG (Becotatug Vedotin injection) is an ADC comprised of an EGFR-targeted monoclonal antibody conjugated with the potent microtubulin inhibiting payload monomethyl auristatin E via a valine-citrulline linker. It is the world's first approved EGFR-targeted ADC and a first-in-class innovation, for the treatment of recurrent or metastatic nasopharyngeal carcinoma (R/M NPC). It binds specifically with high affinity to EGFR on the surface of tumor cells, releases the potent payload upon internalization and lysosomal protease cleavage of the linker and results in tumor cell death. EGFR is highly expressed in colorectal cancer, lung cancer, head and neck cancer and other malignant solid tumors, and is expressed in 89% advanced NPC. Therefore, EGFR is an important target for cancer treatment. About Lepu Biopharma Lepu Biopharma Co., Ltd.

– A potential best- and first-in-class antibody-drug conjugate (ADC) for the treatment of EGFR-expressing solid tumors, ALX2004 is uniquely designed with every component optimized to maximize the therapeutic window -First-in-human trial of ALX2004 builds upon body of positive preclinical data demonstrating dose dependent anti-tumor activity and favorable safety profile -Initial safety data anticipated in first half 2026 SOUTH SAN FRANCISCO, CA, USA I August 19, 2025 I ALX Oncology Holdings Inc., (“ALX Oncology” or the”Company”) (Nasdaq: ALXO), a clinical-stage biotechnology company advancing a pipeline of novel therapies designed to treat cancer and extend patients’ lives, today announced that the first patient has been dosed in the Company’s Phase 1 clinical trial for ALX2004, a potential best- and first-in-class, epidermal growth factor receptor (EGFR) ADC that is being studied for the treatment of EGFR-expressing solid tumors. “Dosing of the first patient in the Phase 1 trial is an important milestone in ALX Oncology’s mission to develop a pipeline of best-in-class drugs; ALX2004 is our first ADC and treating our first patient with this drug is a significant step forward in fulfilling the potential of EGFR-targeted ADCs,” said Jason Lettmann, Chief Executive Officer at ALX Oncology. “Our preclinical data supports our conviction that ALX2004, with its optimized antibody, linker and payload, has the potential to overcome the toxicity challenges that have limited earlier generation EGFR-targeted ADCs. We look forward to enrolling this trial and expect to report initial safety data in the first half of 2026.” The Phase 1 clinical trial ( NCT07085091 ) is a first-in-human, open-label multicenter study evaluating ALX2004 in participants with advanced or metastatic select EGFR-expressing solid tumors. The study consists of a Phase 1a dose escalation portion followed by dose exploration, and a Phase 1b dose expansion. The dose escalation portion of the trial will enroll patients with previously treated advanced or metastatic non-small cell lung cancer (NSCLC), head and neck squamous cell carcinoma (HNSCC), esophageal squamous cell carcinoma (ESCC) and colorectal cancer (CRC). All or a subset of these tumor types may be included in the dose exploration and expansion portions of the trial. ALX2004: Optimized for Success Based on Rigorous Drug Design Process Developed by ALX Oncology’s protein engineers utilizing the Company’s proprietary topoisomerase I inhibitor (Top1i) payload and linker payload platform, ALX2004 is a uniquely designed EGFR-targeted ADC where every component is optimized to maximize the therapeutic window by reducing toxicity. This includes an affinity-tuned EGFR antibody with a binding epitope distinct from approved EGFR antibodies. ALX2004 also has a proprietary Top1i payload engineered to offer enhanced bystander effect with improved linker stability for on-target delivery of payload. Robust Preclinical Data: Supporting Differentiation in EGFR-ADC Class Preclinical data supports ALX2004’s differentiated linker-payload construct, which has demonstrated superior stability versus other ADCs in its class, with dose-dependent activity and a favorable safety profile. In addition, ALX2004 has shown dose-dependent activity across a range of tumors, EGFR expression levels and mutations. Potent activity in tumor models supports its potential for treating patients with EGFR-expressing tumors. Preclinical model findings did not demonstrate EGFR-related skin toxicity at clinically relevant doses or payload-related interstitial lung disease, supportive of a potentially differentiated safety profile.
