Along with these above facts, there are also some challenges while conducting clinical trials in South Korea

Top 3 Challenges with clinical trials in South Korea

  1. Patient Recruitment: Despite having a large patient population, patient recruitment can be challenging in South Korea, particularly for trials involving rare diseases or specific patient populations. This is because patients may be hesitant to participate in clinical trials due to cultural beliefs, language barriers, or concerns about privacy.
  2. Competition from Other Countries: South Korea faces stiff competition from other countries, such as China and Japan, which are also popular destinations for clinical trials. This competition can lead to challenges in attracting sponsors and investment for clinical trials.
  3. Regulatory Hurdles: Although South Korea has a well-established regulatory framework for clinical trials, navigating the regulatory environment can be challenging for researchers and sponsors. The process of obtaining regulatory approval for clinical trials in South Korea can be time-consuming and complex, leading to delays and additional costs.

Requirements to obtain approval for clinical trial initiation

Clinical Trials for medical devices in Korea

  • Foreign companies must first prepare a clinical investigation plan and provide documents proving that their manufacturing facility meets GMP standards to submit a clinical trial application for a medical device in Korea.
  • If the device is used to treat life-threatening illnesses, the Investigational Review Board (IRB) must approve a series of supplementary documents.
  • Medical device trials generally receive approval in Korea within 30 days.

Clinical Trials for Pharmaceuticals in Korea

  • Companies must go through the Clinical Trial Authorization (CTA) process.
  • Before beginning the pharmaceutical clinical trial in Korea, applicants must choose trial sites and a Principal Investigator (PI).
  • Korean PIs must be well educated, trained, and have foreign language abilities.
  • The sponsor and head of the clinical trial site will sign a written contract before the trial begins.
  • If a CRO is used, the sponsor must write a contract outlining a set of tasks for the CRO to complete.

Local Representative

To obtain approval of a clinical trial protocol in South Korea, a foreign company without an established presence in Korea must delegate all rights and responsibilities for the execution of the clinical trial through an agreement with a contract research organization (CRO) established in Korea.

Electronic Filing System (KiFDA)

Korea’s drug clinical trial approval forms can now be submitted through the e-registration system. Applicants and CROs can self-register their products after receiving approval.

CRIS (Clinical Research Information Services)

  • The South Korean government developed a web-based platform called CRIS (Clinical Research Information Services) to facilitate the management of clinical trial information..
  • It is a central database that provides information on ongoing clinical trials conducted in South Korea.
  • The CRIS includes any clinical trial or research which will prospectively conduct with human participants, aiming to prevent, detect, diagnose, or treat diseases. 
  • The IRB should approve the clinical trial before registering it on the CRIS.
  • The Korea Centers for Disease Control and Prevention (KCDC), with support from the Ministry of Health and Welfare (MOHW), established the CRIS.
  • It joined the WHO International Clinical Trials Registry Platform (ICTRP) as an 11th member of the Primary Registry.

Parallel approval process

In South Korea, the application process for both CTA and IRB is parallel.

Step by step clinical trial approval process in South Korea

The clinical trial approval process in South Korea involves several steps, which include:

  • Submission of the clinical trial application: The first step in the approval process is to submit a clinical trial application to the Ministry of Food and Drug Safety (MFDS). The application should include details of the trial protocol, including the study design, objectives, inclusion/exclusion criteria, and endpoints.
  • Ethical review: The Ministry of Food and Drug Safety (MFDS) forwards the application to the Institutional Review Board (IRB) for ethical review once they receive it. The IRB is responsible for reviewing the study protocol to ensure that it meets ethical standards and protects the rights and welfare of study participants.
  • Regulatory review: After receiving ethical approval, the MFDS conducts a regulatory review of the clinical trial application. The regulatory review includes an assessment of the scientific validity of the study, as well as a review of the safety and efficacy data.
  • Approval decision: Once the regulatory review is complete, the MFDS makes a decision on whether to approve the clinical trial application. If the Ministry of Food and Drug Safety (MFDS) approves the application, the sponsor may proceed with the trial.
  • Post-approval reporting: After approval, sponsors must submit regular reports on the progress of the trial to the MFDS. This includes safety reports, interim analysis reports, and final study reports.

Time of approval

The process for regulatory approval takes about 30 days and for IRB, it takes about 50 days.
