The purpose of this study is to evaluate the clinical feasibility, performance, safety and acceptability of the On-body Injector (OBI) when applied to the arm or abdomen of healthy volunteers to inject placebo under the skin.
This study is a monocentric, open-label, cross-over, feasibility and exploratory study with no acceptance criteria. Up to 70 healthy volunteers will be enrolled and followed up for 7 weeks at maximum.

Participant will remain in clinic and wear devices adhered on abdomen or arm approximately 27hrs prior to injection
Device will be applied to the abdomen or arm to deliver placebo subcutaneously. After device application, participant will go home and return to clinic before delivery.

Device Performance - Dose delivery efficiency
Determined by volume - measured via gravimetric analysis (weighing the device)
Time frame: After device removal
Device Performance
Change in adhesive pad adherence - device to skin/device to adhesive pad - determined via adherence scales (Score 0 - 4, whereby 0 is full adherence and 4 is reflecting full detachment)
Time frame: From device application until 15-minutes after injection
Additional OBI performance - Injection signal/indicator performance
Assessed by visual or audible observation from activation to injection end.
Time frame: Before, during and after injection for each applied device; up to 28 hours after application
Additional OBI performance - Catheter condition
Catheter bending assessment by grading
Time frame: Approximately 15-minutes after device removal
Participant Pain
100mm Visual Analog Scale (VAS) for pain assessment - describing no pain with 0mm - up to worst possible pain described with 100mm
Time frame: Immediately before device catheter is inserted, after insertion, during wear period, at start of injection, 15 minutes after injection, end of injection and upon removal for each applied device
Participant Acceptability Questionnaires
Questionnaires to assess participants' acceptability of the device during wear
Time frame: Device acceptability questionnaire will be completed after device catheter is inserted, at 8 hours and 26 hrs after application, during Injection and upon device removal

Ultrasound Imaging of injection site
Measure pre- and post-injection tissue thickness
Time frame: Baseline and immediately after procedure for each applied device
Tissue Effects
Assessment of wheal and erythema described via grading 0-4, incidence of bleeding, bruising, induration
Time frame: Baseline, immediately after procedure, follow up check up to 72 hours after injection in case tissue effects are present
Adverse Events
Incidence of adverse device effects and procedure related adverse events
Time frame: Throughout study completion, an average of 4 week
