KB707-02: A Phase 1 Study of Inhaled KB707 in Patients With Advanced Solid Tumor Malignancies Affecting the Lungs

KB707-02

The Sponsor is developing KB707, a replication-defective, non-integrating herpes simplex virus type 1 (HSV-1)-derived vector that is designed to stimulate an anti-tumor immune response through the production of cytokines delivered to the airways of people with advanced solid tumor malignancies affecting the lungs via nebulization. This Phase 1, open-label, multicenter, dose escalation and expansion study is designed to evaluate the safety and tolerability of KB707 in adults with with advanced solid tumor malignancies affecting the lungs who have progressed on standard of care therapy, cannot tolerate standard of care therapy, or refused standard of care therapy. The study will include a dose escalation portion for single agent KB707 using a standard 3+3 design followed by an expansion portion to further evaluate single agent KB707 at a dose determined by preliminary data in the dose escalation phase. Subjects in both the dose escalation and dose expansion cohorts will receive KB707 via nebulization weekly for three weeks, then every three weeks for up to two years until tumor progression, death, unacceptable toxicity, symptomatic deterioration, achievement of maximal response, subject choice, Investigator decision to discontinue treatment, or the Sponsor determines to terminate the study.
