Post-TURBT direct-injection and intravesical LSAM-DTX was well tolerated and demonstrated clinical response for patients with high-risk NMIBC. Favorable immune cell infiltration and checkpoint receptor increases following LSAM-DTX treatment warrants investigation alone as well as in combination with immune checkpoint inhibitor therapy.

LSAM-DTX treatment was safe by both intramural injection and intravesical instillations. PK analysis demonstrated negligible systemic exposure. Preliminary efficacy data suggest post-TURBT intramural injection and intravesical instillation of high dose LSAM-DTX may prevent recurrence in patients with hrNMIBC for 6-months.
Myeloid-derived suppressor cells (MDSC) were reduced in bloods in SPD ± anti-mCTLA-4 groups (p < 0.05). These data demonstrate that both SPD and anti-mCTLA-4 produce local anti-tumor effects as well as reductions in metastasis which are significantly enhanced when administered in combination.

CD4+, CD8+ and Treg populations were increased in peripheral bloods from animals administered IT NanoDoce. Additional evaluation of the effect of IT NanoDoce on peripheral and local immune cell populations as well as the impact on sites of distant tumor growth are warranted.
