This is a Phase 1 study designed to test the tolerability and feasibility of intravesical therapy with an attenuated Measles virus (MV-NIS) in patients with urothelial carcinoma who are undergoing radical cystectomy but are ineligible or do not desire neoadjuvant chemotherapy.
Study VYR-MV1-102 is a Phase 1 study designed to determine the tolerability, feasibility and
preliminary efficacy of attenuated MV-NIS virus after neoadjuvant intravesical administration
prior to RC in patients with UC who are ineligible for current neoadjuvant chemotherapy.
We will use a novel adaptive trial design that varies the time between TURBT, virus
administration and RC. Currently, intravesical administration of BCG is delayed four to six
weeks after TURBT to reduce the likelihood of systemic BCG absorption and BCG sepsis. Given
this clinical safety precedent, we propose initial patients be treated within one week of RC
to maximize the time between TURBT and MV-NIS administration. Subsequent patients will be
treated earlier before RC (up to 29 days prior), thereby reducing the interval between TURBT
and virus administration to maximize the treatment duration before RC. An expansion cohort
will also be used to test the feasibility, tolerability and efficacy of two repeat MV-NIS
doses prior to RC. MV-NIS has been proven safe at a dose of 1x1011 TCID50 intravenously in
patients lacking MV immunity (Russell 2014), which allays concern for systemic toxicity after
intravesical administration even if post-TURBT administration results in systemic MV-NIS
absorption. Pathologic downstaging and CR (assessed by T0 rate) at surgery are secondary
endpoints, designed to give an early indication of efficacy potential. This will facilitate
future virotherapy strategies targeting replicative tumor destruction and stimulation of
systemic anti-tumor immunity as possible strategies for neoadjuvant and bladder-sparing
