– Company plans to initiate a Phase 1/b trial in relapsed/refractory, locally advanced/metastatic bladder cancer by year-end
HAYWARD, CA, USA I February 10, 2025 I Rondo Therapeutics, a privately held biopharmaceutical immuno-oncology company pioneering the development of next-generation T cell-engaging bispecific antibodies for the treatment of solid tumors, today announced that data from preclinical studies of RNDO-564, a novel CD28 x Nectin-4 costimulatory bispecific antibody for advanced bladder cancer, is being presented in a poster session at the 2025 American Society of Clinical Oncology (ASCO) Genitourinary (GU) Cancers Symposium, taking place February 13-15, 2025, in San Francisco, CA.
“CD28 co-stimulatory bispecific antibodies are designed to boost T cell-mediated tumor killing and overcome T cell exhaustion in the solid tumor microenvironment. In preclinical studies, RNDO-564 demonstrated robust anti-tumor activity in vivo and in vitro, including in an antibody drug conjugate (ADC)-resistant bladder cancer model, suggesting the ability of RNDO-564 to overcome T cell exhaustion and address limitations of ADCs, including toxicity, resistance, and sequential ADC re-challenge,” said Thomas Manley, CMO of Rondo Therapeutics. “Based on these promising preclinical findings, we are advancing RNDO-564 through IND-enabling studies, with the goal of entering the clinic in advanced bladder cancer by year-end.”
Key Findings
RNDO-564 is designed to elicit robust Nectin-4 and signal-1 dependent T-cell mediated killing of Nectin-4-expressing tumor cells
RNDO-564 restored tumor cell killing function of serially stimulated T cells in vitro
RNDO-564 inhibited tumors in vivo as monotherapy and in combination with checkpoint therapy in vivo
Preliminary toxicology studies support clinical evaluation of RNDO-564
RNDO-564 maintained cytotoxicity against antibody drug conjugate-resistant bladder cancer cells
