Brief Summary
The goal of this clinical trial is to determine safety, tolerability, pharmacokinetics, preliminary efficacy, and Maximum Tolerable Dose (MTD), of intralesional FLD-103 when administered to subjects with Basal Cell Carcinoma (BCC). The main questions it aims to answer are:
- Is FLD-103 safe and well tolerated?
- What is a safe dose of FLD-103 for future studies?
- How much FLD-103 enters the bloodstream and how long does it take to be cleared from the body?
- Does FLD-103 reduce the size of the tumor? Participants will:
- Receive either a Single Ascending Dose (SAD) of FLD-103 or Multiple Ascending Doses (MAD) of FLD-103 once weekly for four (4) weeks.
- Visit the clinic a day after receiving a dose and once weekly for four (4) weeks after that for checkups and tests.
