Clinical Study with Screening May 18th


P-One Clinic (Hachioji, Tokyo) is seeking male participants for an upcoming clinical study with study groups beginning in May and June.


Clinical studies (also called “clinical trials”) are scientific tests to check the efficacy and safety of new drugs, medical devices, and healthcare procedures. They are conducted with the cooperation of willing volunteers and governed by the strict legal and ethical guidelines of Good Clinical Practice (GCP). By participating in a clinical study, you play a crucial role in helping to get new medicines to the patients who need them.


P-One Clinic (Hachioji, Tokyo) is seeking healthy males for two upcoming study cohorts. Those who pass the initial selection will be invited to an information/consent session and screening health check. Those who pass the screening will be invited to take a PCR test approximately 2 weeks later and then to participate in a test of a drug. They will stay overnight at the clinic for 15 nights and return several days later for a single follow-up health check.
