A Clinical Study Evaluating the Dermal Safety of Soluble Denosumab Microneedle Patches
Sponsor: Union Hospital, Tongji Medical College, Huazhong University of Science and Technology
Summary
The goal of this clinical trial is to evaluate the skin safety of a soluble denosumab microneedle patch in participants with osteoporosis and osteoarthritis. The main questions it aims to answer are: * Is the soluble denosumab microneedle patch safe for use on the skin? * What are the potential skin reactions to the patch? Researchers will compare different doses of the microneedle patch to assess its safety. Participants will: * Apply the microneedle patch to four different areas around their knee * Undergo skin assessments at various time points after application * Be monitored for any adverse skin reactions The study will take place at a single center and involve a small number of participants to provide preliminary data on the safety of this novel drug delivery system.

Interventions
Microneedle with 0.24mg Denosumab
This intervention uses microneedle patches loaded with 0.24mg of denosumab. The patch is made of a biocompatible material, polyvinyl pyrrolidone (PVP), and is applied to the skin around the knee. It aims to evaluate the skin safety and tolerability of the microneedle patch at this specific dose. Participants will apply 4 microneedle patches around their knee and avoid behaviors that may affect skin condition during the study.
Saline Microneedle Patch
This intervention involves the use of a microneedle patch loaded with saline. The patch is made of a biocompatible material, polyvinyl pyrrolidone (PVP), and is applied to the skin around the knee. It serves as a control to assess the skin safety of the microneedle patch without the active drug. Participants will apply 4 microneedle patches around their knee and avoid behaviors that may affect skin condition during the study.
Microneedle with 1.2mg Denosumab
This intervention uses microneedle patches loaded with 1.2mg of denosumab. The patch is made of a biocompatible material, polyvinyl pyrrolidone (PVP), and is applied to the skin around the knee. It aims to evaluate the skin safety and tolerability of the microneedle patch at this specific dose. Participants will apply 4 microneedle patches around their knee and avoid behaviors that may affect skin condition during the study.
Microneedle with 6mg Denosumab
This intervention uses microneedle patches loaded with 6mg of denosumab. The patch is made of a biocompatible material, polyvinyl pyrrolidone (PVP), and is applied to the skin around the knee. It aims to evaluate the skin safety and tolerability of the microneedle patch at this specific dose. Participants will apply 4 microneedle patches around their knee and avoid behaviors that may affect skin condition during the study.
