A Study Assessing KB707 for the Treatment of Locally Advanced or Metastatic Solid Tumors
Study Details
Study Description
Brief Summary
KB707-01 is a Phase 1, open-label, multicenter, dose escalation and expansion study to evaluate the safety and tolerability of KB707 in adults with locally advanced or metastatic solid tumors who have progressed on standard of care therapy, cannot tolerate standard of care therapy, refused standard of care therapy, or for whom there is no standard of care therapy. In this study, patients will receive KB707 via direct intratumoral (IT) injection into solid tumors to assess the safety and tolerability as well preliminary efficacy of KB707 monotherapy treatment.

Detailed Description
KB707 is a genetically modified herpes simplex type 1 virus that is designed to stimulate an anti-tumor immune response through the production of cytokines. This is a first-in-human (FIH) clinical study to evaluate the safety and tolerability, biodistribution, shedding, and preliminary efficacy of KB707 in adult subjects with advanced and/or refractory solid tumors. The study will include a dose escalation portion for single agent KB707 and an expansion portion to further evaluate single agent KB707 at a dose determined by preliminary data in the dose escalation phase.
