Intervention model description
Module 1 consists of treatment with AZD6750 administered as a single agent to enroll participants with select locally advanced or metastatic solid tumors who have received prior adequate SoC. Select solid tumors include the tumor types known to show activity with ICIs (either as a single agent or in combination with other anti-cancer agents) or include reports potentially showing benefit of IL-2. Module 1 will consist of Part 1A (dose escalation). The combination arm (Module 2) will open on agreement with SRC, and will investigate AZD6750 and rilvegostomig, enrolling participants with Stage IV NSCLC who either received at least one line of therapy in metastatic setting or are treatment naïve in metastatic setting and have a PD-L1 expression ≥ 1%. Module 2 will consist of an escalation arm (Module 2A) and an expansion arm (Module 2B). Dose expansion (Module 2B) may open further to characterize preliminary efficacy of AZD6750 in combination with rilvegostomig.
