Preliminary evidence shows that a single dose of INT230-6 can cause significant intratumoral necrosis compared to saline especially in tumors >2. cm. INT230-6 stimulates an immune response in breast cancers prior to surgery with minimal adverse effects and good tolerability.
INT230-6 use was associated with immune infiltration and a clinically relevant mOS particularly when ≥40% of the TTB was injected. Uninjected tumors shrank in a high percentage of monotherapy subjects. INT230-6 dosed IT alone or with IPI had favorable safety in diverse sarcomas.
Intratumoral INT230-6 appears well-tolerated in this heterogenous soft tissue sarcoma population, and early safety with the IPI combination appears favorable. INT230-6 monotherapy treatment resulted in encouraging signs of tumor burden reduction in injected and non-injected lesions, and immune activation. Given the poor cor- 93 relation of RECIST responses and OS in this population, preliminary analysis of OS from this study compares favorably to historical results from a P1/2 basket sarcoma study with a similar, heavily pretreated, heterogeneous sarcoma population balanced for three prognostic health criteria: albumin and lactase dehydrogenase levels and a subject’s number of metastatic sites.
