The purpose of this Phase 1 study is to initiate clinical development of gNO in patients with unresectable cutaneous or subcutaneous primary or metastatic solid tumors that are not amenable or have failed standard treatment, for which no therapy of proven efficacy exists, or which has progressed despite standard therapy. This study of gNO treatment will consist of 2 parts: a dose-escalation part to establish a safe and tolerable dose of gNO in patients with primary or metastatic unresectable cutaneous or subcutaneous solid tumors (Part A), and a dose expansion phase (Part B) which may be initiated at the Sponsor's discretion after the maximum tolerated dose (MTD) (or recommended Phase 2 dose [RP2D]) has been determined in the dose-escalation phase (Part A). This study will be the basis for future studies.
This is a Phase 1, open-label, dose-escalation and dose-expansion study comprised of a screening period, a single treatment session, and follow-up period of up to Day 60±5 days post-treatment.
