To Assess the Safety and Efficacy of SP-002 with Vismodegib for the Treatment of Locally Advanced Basal Cell Carcinoma

This is a Phase 2, 3-arm, multi-center, open-label, randomized, clinical study to evaluate the efficacy of SP-002 in combination with vismodegib in subjects with locally advanced Basal cell carcinoma. The study will be completed in 2 consecutive parts. Each part consists of a screening period, a treatment period, and a follow-up period. * Part A: 20 participants who meet study entry criteria will be randomized in a 1:1 ratio into 2 treatment arms (Arm 2 and Arm 3) and will provide preliminary safety and performance in a population with target Basal cell carcinoma lesions. * Part B: 60 participants who meet study entry criteria will be randomized in a 1:1:1 ratio into 3 treatment arms (Arm 1, Arm 2, and Arm 3) in a population with target Basal cell carcinoma lesions.
