Develops bispecific therapeutic antibodies that engage immune cells to target and eliminate solid tumors, particularly those resistant to immune checkpoint inhibitors. By optimizing the potencies of immune-engaging arms and improving tumor localization, these antibodies aim to provide effective treatment with reduced side effects, addressing critical gaps in cancer immunotherapy.

Problem
Many solid tumors are resistant to existing immune checkpoint inhibitors, leaving a significant unmet need for effective cancer immunotherapies. Traditional bispecific antibody designs optimized for blood cancers often fail to translate effectively to solid tumors due to dose-limiting toxicities and poor tumor localization.
Solution
Rondo Therapeutics develops next-generation, immune-cell engaging bispecific antibodies engineered to target and eliminate solid tumors. Their antibodies are designed to maximize efficacy while minimizing side effects by tuning the potencies of immune-engaging arms and improving tumor localization. This approach aims to provide clinicians with flexible dosing strategies and combination regimens to deliver optimal results for patients with solid tumors. The company utilizes NGS-based antibody discovery to rapidly develop diverse binding arm collections and employs proprietary functional and developability screens to identify clinically viable molecules.
Target Audience
The primary target audience includes clinicians treating solid tumors, as well as pharmaceutical companies seeking strategic partnerships for synergistic advancement of clinical assets.
