Based on public information, we have studied EACTs since 2016, when the EACT system was launched in Japan. In this study, we investigated the reality of EACTs by interviewing pharmaceutical companies and clarifying how they view them.Patients and Methods: We conducted semi-structured interviews with 10 pharmaceutical companies developing new drugs. This study aims to clarify the status of EACTs, so we selected pharmaceutical companies that develop innovative drugs for which they may perform EACTs (however, experience in conducting EACTs was optional).Results: All those surveyed were aware of EACTs. Twelve access clinical trials were conducted, and the EACT implementation rate for pivotal clinical trials was 2.5%. The most common reason for implementing an EACT was “requests from physicians and medical institutions” (nine companies, 90.0%), and the most common reason for not implementing an EACT was “the applicability of the system” (five companies). Improvements to EACTs were identified by eight companies (80.0%); financial assistance by six companies (60.0%); reducing the scope of data to be collected and simplifying the procedure by six companies (60.0%). Seven companies (70.0%) responded that a Single Patient Investigational New Drug Application should be conducted, suggesting that the system should be revised.Conclusion: An interview survey of ten pharmaceutical companies developing new drugs in Japan regarding expanded access clinical trials indicated that there were issues with the system. Many wished to improve the system by establishing a single patient access system, supporting resources, and simplifying procedures. Based on our interviews with 10 Japanese pharmaceutical companies, it was found that the system needed to be improved by introducing a single patient access system, providing supporting resources, and simplifying procedures. In Japan, about eight years have passed since EACT was established, and it appears a revision of the EACT legislation is due.Keywords: clinical trials, investigational new drugs, patient access, semi-structured interview
