“The CANON (CAVATAK in NON-muscle invasive bladder cancer) study evaluated a novel ICAM-1-targeted immunotherapeutic-coxsackievirus A21 as a novel oncolytic agent against bladder cancer.
…
Clinical activity of CAVATAK was demonstrated by induction of tumour inflammation and haemorrhage following either single or multiple administrations of CAVATAK in multiple patients, and a complete resolution of tumour in one patient. Whether used alone or in combination with mitomycinC, CAVATAK caused marked inflammatory changes within NMIBC tissue biopsies by up-regulating interferon-inducible genes including both immune checkpoint-inhibitory genes (PD-L1 and LAG3) and Th1-associated chemokines as well as induction of the innate activator RIG-I, compared to bladder cancer tissue from untreated patients. No significant toxicities were reported in any patient, from either virus or combination therapy.”
