维立志博二战港交所：核心管线商业化前景或有限 三年亏近十亿现金已无法覆盖短债

Core Viewpoint - Nanjing Weilizhibo Biotechnology Co., Ltd. (Weilizhibo) has submitted a prospectus to the Hong Kong Stock Exchange for an IPO, aiming to list on the main board, with Morgan Stanley and CITIC Securities as joint sponsors. The company previously attempted to list in November 2024 but the prospectus became invalid [1][2]. Company Overview - Founded in 2012, Weilizhibo is a clinical-stage biotechnology company focused on discovering, developing, and commercializing innovative therapies for cancer, autoimmune diseases, and other major illnesses. The company has raised approximately $151 million through eight financing rounds, attracting notable investors [1][9]. Financial Performance - Weilizhibo has reported significant losses over the past three years, totaling nearly 1 billion yuan. The company has been operating at a loss, with cash flow continuously negative. As of March 2025, the company had 431 million yuan in cash, which is insufficient to cover its current liabilities of 462 million yuan [2][9][10]. Product Pipeline - The company has a pipeline of 14 drug candidates, with six in clinical stages. The core product, LBL-024, is a PD-L1 and 4-1BB bispecific antibody currently in a pivotal clinical trial for lung neuroendocrine carcinoma. However, the patient population for this indication is small, and the clinical trial phase II has a high failure rate [3][6][8]. Clinical Trial Insights - LBL-024 has shown an objective response rate of 33.3% and a disease control rate of 51.1% in treating advanced lung neuroendocrine carcinoma. Despite promising clinical data, the commercial prospects are limited due to the small patient population, with only 12,000 patients estimated in China for this condition in 2024 [6][8]. Partnership and Collaboration - The company lost its only revenue-generating partnership with BeiGene, which terminated the licensing agreement for LBL-007. This has raised concerns about the company's ability to generate income from its pipeline [2][8]. Investor Dynamics - Prior to the IPO, several early investors chose to liquidate portions of their holdings. The company has reached an agreement with its pre-IPO investors to terminate the share redemption obligation, which has improved its asset structure [10][11][12].
