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.

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.
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.
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.
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.

Number of Participants With Adverse Reactions
Evaluate through skin response sheets: erythema, pain, swelling, etc.
Time frame: Assessed at 15 minutes, 24 hours, 48 hours, and 2 weeks post-application.
Amount of pain
Pain will be measured using the faces pain scales revised (0-2-4-6-8-10, 0: no pain, 10: very much pain).
Time frame: Assessed at 15 minutes, 24 hours, 48 hours, and 2 weeks post-application.
Number of injection site reactions
Injection site assessment for the following: Pain (grade 1/2/3) Tenderness (grade 1/2/3) Pruritus (grade 1/2/3) Erythema (absent/present) Induration (grade 1/2/3) Blister (absent/present) Ulceration (absent/present) Necrosis (absent/present) Ecchymosis (absent/present) If any of these signs or symptoms is present, it is regarded an injection site reaction.
Time frame: Assessed at 15 minutes, 24 hours, 48 hours, and 2 weeks post-application.
Soluble Denosumab Microneedle Patch Subject Satisfaction Questionnaire
Assessed through questionnaires at the end of the study. 1. How satisfied are you with the application process of the microneedle patch? 2. How satisfied are you with the overall skin condition around the knee after using the microneedle patch? 3. Overall, how satisfied are you with the ease of using the microneedle patch? 4. Overall, now that you have tried this microneedle patch and completed the study, how likely are you to use this treatment again in the future? 5. Overall, how likely are you to recommend this microneedle patch treatment to a family member or friend? 5 = Very Likely; 4 = Somewhat Likely; 3 = Neutral; 2 = Somewhat Unlikely; 1 = Very Unlikely
Time frame: Assessed at 2 weeks post-application.
Number of participants with abnormal laboratory tests results
Evaluation of blood routine and blood electrolytes to monitor participants' health status and safety.
Time frame: Assessed at 2 weeks post-application.
