Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Microneedle with Saline

This study arm uses microneedle patches loaded with saline as a control to assess the skin safety of the microneedle patches. Participants will apply 4 microneedle patches around their knee and avoid behaviors that may affect skin condition during the study.

Group Type PLACEBO_COMPARATOR

Saline Microneedle Patch

Intervention Type DRUG

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 0.24mg Denosumab

This study arm uses microneedle patches loaded with 0.24mg of denosumab to evaluate the skin safety and tolerability of the microneedle patch. Participants will apply 4 microneedle patches around their knee and avoid behaviors that may affect skin condition during the study.

Group Type EXPERIMENTAL

Microneedle with 0.24mg Denosumab

Intervention Type DRUG

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.

Microneedle with 1.2mg Denosumab

This study arm uses microneedle patches loaded with 1.2mg of denosumab to evaluate the skin safety and tolerability of the microneedle patch. Participants will apply 4 microneedle patches around their knee and avoid behaviors that may affect skin condition during the study.

Group Type EXPERIMENTAL

Microneedle with 1.2mg Denosumab

Intervention Type DRUG

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 study arm uses microneedle patches loaded with 6mg of denosumab to evaluate the skin safety and tolerability of the microneedle patch. Participants will apply 4 microneedle patches around their knee and avoid behaviors that may affect skin condition during the study.

Group Type EXPERIMENTAL

Microneedle with 6mg Denosumab

Intervention Type DRUG

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.
