Details of the Clinical Studies

Phase III Study: Malignant Ascites

• Study No.: 104
• Title: Phase III, multicenter, randomized, controlled open-label study of M701 in advanced epithelial tumors with malignant ascites
• Presenter: Xu Jianming, The First Medical Center of Chinese PLA General Hospital
• Presentation Date: May 31, 2026
• Significance: The oral presentation format is a mark of distinction at ASCO, reflecting the high clinical and academic value of the M701 program in addressing malignant ascites—a severe complication in advanced cancer patients with limited treatment options.

Phase II Study: Malignant Pleural Effusion (MPE) in NSCLC

• Study No.: 12061
• Title: A prospective randomized controlled Phase II study of M701 in NSCLC-related MPE
• Presentation Format: Poster presentation
• Presentation Date: May 30, 2026
• Significance: This study addresses MPE in NSCLC patients, further expanding M701’s potential applications and laying groundwork for future clinical development and indication expansion.

Strategic and Clinical Implications

• M701’s Innovation: M701 is a recombinant anti-epithelial cell adhesion molecule (EpCAM)/CD3 bispecific antibody, designed to redirect T cells to kill tumor cells, offering a novel therapy for malignant serous cavity effusion (ascites and pleural effusion).
• The selection of both studies for ASCO presentations strongly underscores international academic recognition and validates the clinical progress of M701.
• Market Impact: Such recognition at ASCO can significantly raise the profile of Wuhan YZY Biopharma within the global oncology community and industry, potentially accelerating clinical collaborations, commercialization, and attracting investor interest.
• Unmet Clinical Need: Malignant ascites and pleural effusion are common, life-altering complications in advanced cancer. Current therapies are limited, and M701 addresses a clear, high-value unmet medical need.
• Continued Clinical Development: The company intends to advance M701’s clinical development and international collaboration, aiming to bring innovative treatments to patients worldwide.

Important Shareholder Information

• Price Sensitivity: The selection of M701’s pivotal trials for ASCO—especially an oral presentation for a Phase III study—represents a significant milestone that could positively influence investor sentiment and potentially impact share price.
• Risk Disclosure: Despite these achievements, the company cautions that M701 is still under development and not yet approved or marketed. There is no guarantee of successful commercialization.
• Board Composition: The board comprises a mix of executive, non-executive, and independent directors, led by Dr. Zhou Pengfei (Chairman, Executive Director, and CEO).
