[Evaluation of Pharmacy Students' Understanding of Clinical Trials and Research through Questionnaires Before and After the Hospital Practical Training].

A questionnaire survey was conducted to evaluate practical training and improve education on clinical trial and research. This survey was based on the results of questionnaire before and after the practical training undertaken by 240 pharmaceutical students (Kanto region; 1 university, Tokai region; 2 university, Kinki region; 9 university) at Mie University Hospital between 2011 and 2022. In the questionnaire before practical training, lectures in university (n=219, 91%) were the main source of information on clinical trials and research. Fifty-two students (22%) correctly answered the contents of phase 1-4 trials. As an occupation that can perform clinical research coordinator (CRC)'s work, only 7 students (3%) answered that "all medical and non-medical professionals" can perform the CRC's duties. Regarding the understanding of terms related to clinical trials and research, more than 90% of the students understood the meaning of "subjects," "informed consent," and "placebo" even before practical training. Otherwise, even after practical training, students' understanding of "reimbursement," "follow-up period," "audit," or "direct access" was less than 80%. Practical training improved the understanding of terms such as clinical trial (Wilcoxon signed-rank test, p<0.001), clinical research phase 1-4 trials (Wilcoxon signed-rank test, p<0.001), interest in clinical trials and research (McNemar-Bowker test, p<0.001), and understanding of CRC's work (McNemar-Bowker test, p<0.001). We will improve the content of practical training and bequeath the knowledge and importance of drug discovery and development to the next generation.

TADAFER II: Tadalafil treatment for fetal growth restriction - a study protocol for a multicenter randomised controlled phase II trial.

INTRODUCTION: There is no proven therapy to reverse or ameliorate fetal growth restriction (FGR). Sildenafil, a selective phosphodiesterase 5 (PDE5) inhibitor, has been reported to potentially play a therapeutic role in FGR, but this has not been established. Tadalafil is also a selective PDE5 inhibitor. We have demonstrated the efficacy of tadalafil against FGR along with short-term outcomes and the feasibility of tadalafil treatment. Based on the hypothesis that tadalafil will safely increase the likelihood of increased fetal growth in FGR, we designed this phase II study to prospectively evaluate the efficacy and safety of tadalafil against FGR. METHODS AND ANALYSIS: This study is a multicentre, randomised controlled phase II trial. A total of 140 fetuses with FGR will be enrolled from medical centres in Japan. Fetuses will be randomised to receive either the conventional management for FGR or a once-daily treatment with 20 mg of tadalafil along with the conventional management until delivery. The primary endpoint is fetal growth velocity from the first day of the protocol-defined treatment to birth (g/day). To minimise bias in terms of fetal baseline conditions and timing of delivery, a fetal indication for delivery was established in this study. The investigator will evaluate fetal baseline conditions at enrolment and will decide the timing of delivery based on this fetal indication. Infants will be followed up for development until 1.5 years of age. ETHICS AND DISSEMINATION: This study was approved by the Institutional Review Board of Mie University Hospital and each participating institution. Our findings will be widely disseminated through peer-reviewed publications. TRIAL REGISTRATION NUMBER: UMIN000023778.
