On March 30, 2022, the National Medical Products Administration issued a notice (No. 30 of 2022) on adjusting some contents of the "Classification Catalogue of Medical Devices", which includes adjustments to the contents of the "Classification Catalogue of Medical Devices" for 27 categories of medical devices. According to the relevant requirements of this announcement, radiofrequency beauty equipment is clearly managed as a Class III medical device. For the radio-frequency skin therapeutic instrument products in the 09-07-02 radio-frequency treatment (non ablation) equipment involved in the adjustment in the annex, from the date of the announcement, it is necessary to apply for registration in accordance with the Administrative Measures for the Registration and Filing of Medical Devices (Order No. 47 of the State Market Supervision and Administration). Starting from April 1, 2024, radiofrequency skin therapy devices cannot be produced, imported, or sold without obtaining a medical device registration certificate in accordance with the law. Starting from April 1, 2024, enterprises that have not obtained a medical device production and operation license (filing) are not allowed to engage in the production and sale of related products.In April 2023, the Medical Device Technical Evaluation Center of the National Medical Products Administration issued the "Guiding Principles for Registration and Review of Radiofrequency Beauty Devices". The clinical evaluation requirements for radiofrequency beauty devices in the guiding principles should refer to the recommended path for clinical evaluation of products related to "Physical Therapy Devices" in subdirectories 09 of the "Classification Catalogue of Medical Devices". Recommend conducting relevant evaluations through clinical trial pathways. At this critical juncture of regulatory upgrading in the industry, Zhuyitong has been entrusted by Prometheus Miracle (Shenzhen) Medical Technology Co., Ltd. with full responsibility for the clinical trial project of its radiofrequency skin therapy device, based on its professional reputation. This fully demonstrates the applicant's deep trust in Zhuyitong.2、 Project milestonesThe clinical trial of this project lasted approximately one year from the finalization of the protocol design to the release of the trial summary report. From the initial stage of the project's clinical trial plan design, the team collaborated with multiple medical beauty clinical experts and data statisticians to conduct multiple rounds of argumentation, repeatedly optimizing inclusion/exclusion criteria, evaluation indicators, and sample size calculation models to ensure that the plan not only meets the requirements of the "Guidelines for Registration and Review of Radiofrequency Beauty Equipment", but also has clinical operability; Screening and conducting research at the center, inspecting the medical beauty departments of multiple tertiary hospitals across the country, and ultimately determining two clinical centers that meet the requirements; In the ethical approval stage, actively cooperate with the hospital's ethical requirements to submit materials, complete the ethical meeting of the team leader unit within one month and obtain approval; And the subsequent center launch meeting organization, full cycle management of subjects (with a cumulative follow-up dropout rate of only 1.4%), third-party inspection cooperation (no major quality issues), data statistical analysis, until the writing of the summary report and submission of registration materials, each link embodies the hard work of the Zhuyitong team.During the project promotion process, as the handheld radiofrequency skin therapy device was first placed under medical device supervision, there was neither consensus among clinical experts nor clinical precedents to refer to in China. During the process of scheme design and review, relevant parties actively communicated and cooperated, successfully completing all clinical trials and review Q&A, and ultimately obtaining approval.3、 Project milestonesAt the end of November 2024, the project will undergo on-site inspection by the National Medical Products Administration. Zhuyitong dispatched all trial participants to provide on-site assistance throughout the entire process, offering professional technical support and process coordination to ensure efficient and smooth verification work, further confirming the team's professional ability and responsible attitude.
