Study of Intralesional FLD-103 in Subjects With Basal Cell Carcinoma (BCC)

A Phase 1, First-In-Human, Single and Multiple Ascending Dose Escalation Study to Evaluate the Safety, Tolerability, Pharmacokinetics and Preliminary Clinical Efficacy of Intralesional FLD-103 in Subjects With Basal Cell Carcinoma (BCC).

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.

Inclusion Criteria:

• You are between 18 and 85 years old.
• You are willing to attend all study visits and follow the study procedures.

• You are willing to avoid certain medications during the study as instructed by the study doctor.
• You are not currently participating in another clinical study.
• If you are a woman who could become pregnant, you must:
• Have a negative pregnancy test at the start of the study.
• Use effective birth control during the study and for 90 days after your last dose.
• Not breastfeed during the study and for 90 days after your last dose.
