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.

Background: INT230-6 is comprised of cisplatin (CIS), vinblastine (VIN) and an amphiphilic penetration enhancer which facilitates dispersion throughout tumors and diffusion into cancer cells when given IT. Proof of concept was demonstrated that INT230-6 delivers high drug doses into the tumor without systemic exposure and typical cytotoxic AEs. Systemic and local immune activation was observed. INT230-6 was safe and well tolerated in > 175 deep tumor injections with tumor burden reduction in injected and non-injected tumors (an abscopal effect).
