CTIM-05. COMBINATION OF CONTROLLED INTERLEUKIN-12 GENE THERAPY WITH IMMUNE CHECKPOINT BLOCKADE IN RECURRENT GLIOBLASTOMA: UPDATED RESULTS OF A MULTI-INSTITUTIONAL, OPEN LABEL PHASE 1 TRIAL

ABSTRACT: Abstract A published clinical trial of veledimex (V)-regulatable interleukin-12 (IL-12) gene therapy (“Controlled IL-12”) under the control of a transcriptional switch (RheoSwitch Therapeutic Systemâ, RTSâ) as monotherapy in recurrent glioblastoma (rGBM) showed sustained infiltration of activated T cells within the tumor months after treatment (Sci Transl Med. 2019;11(505)). These T cells demonstrated up-regulation of immune checkpoint signaling, providing a rationale for combination therapy with the PD-1 inhibitor, nivolumab (nivo). We report interim findings following completion of enrollment (with follow-up ongoing) for a multi-institutional, open label, dose-escalation phase 1 trial (NCT03636477) evaluating safety and tolerability of loco-regional Controlled IL-12 in combination with n
