Rondo Therapeutics Publishes Preclinical Data on RNDO-564, a Novel CD28 x Nectin-4 Co-Stimulatory Bispecific Antibody for the Treatment of Bladder Cancer (Businesswire) - "Rondo Therapeutics...announced the publication detailing the discovery and preclinical development of RNDO-564, a CD28 x Nectin-4 bispecific antibody in the Journal for ImmunoTherapy of Cancer (JITC)....Key findings for RNDO-564: Elicits robust Nectin-4 and signal-1 dependent T-cell mediated killing of Nectin-4-expressing tumor cells. Enhances T-cell function in settings with mixed Nectin-4 positive and negative target cells. Restores tumor cell killing function of serially stimulated T cells in vitro. Fully eliminates established tumors in in vivo mouse model as monotherapy and in combination with a checkpoint inhibitor. Preliminary tolerability studies in non-human primates demonstrate safety and support clinical evaluation of RNDO-564."

Potency-optimized CD28-activating bispecific antibody for the targeted treatment of Nectin-4 positive cancers. (PubMed, J Immunother Cancer) - "Our study reports the first CD28 bsAb targeting Nectin-4 and highlights the potential of CD28 × Nectin-4 bsAbs as a new immunotherapeutic modality. The findings support the clinical development of RNDO-564 in patients with locally advanced and metastatic UC and other Nectin-4 positive malignancies."

A novel CD28 x Nectin-4 costimulatory bispecific antibody for advanced bladder cancer. (ASCO-GU 2025) - "Background: Effective T-cell activation is driven by multiple signals. RNDO-564 has a high affinity Nectin-4 binding arm and an affinity-tuned CD28 arm optimized for activity in metastatic bladder cancer. A phase 1 study is planned to evaluate the safety, tolerability, PK/PD, and clinical activity of RNDO-564 alone and in combination with CPI in mUC."
