This thesis has studied about the legal characteristic of injection of the trial drug, the position of the pharmaceutical firm as a contractor of the clinical trial, the possibility of compulsory performance of consistent injection of the trial drug, and the damage claim caused in the process of the clinical trial from the viewpoint of protecting the trial subject in the clinical trial. According to court's judgement in the United States, the lawsuit of the trial subject, although the trial subject had expected consistent injections, was dismissed because there was no direct contract between pharmaceutical and trial subject. However, Helsinki Declaration prescribe the medical research as follows. 'All patients who participated in the research should be able to use the best precaution, diagnosis, and treatment proved by the final outcome of the research'. The trial subject is entitled to demand only the pharmaceutical firm which developed and provided the trial drug, and the pharmaceutical firm has the obligation to supply the trial drug to the trial subject. Therefore, it would be not enough to protect the trial subject if the pharmaceutical firm which makes the trial drug is ruled out. In addition, especially, in case the trial drug has a constant effect with the aim of treatment, if the injection of the trial drug is suddenly stopped, the trial subject would not have the benefit of treatment by the trial drug. In this case, the best remedy against the damage is to urge a constant injection of the trial drug. Thus, in certain case, it is reasonable to consider that the pharmaceutical firm has the obligation to supply the trial drug to the trial subject constantly, and it is also necessary to compel it through effective means in case the pharmaceutical firm do not fulfill its obligation to supply the trial drug. However, as an essential prerequisite for the assertion mentioned above, it should be judged under the principle of good faith considering the concrete situation, that is, what roles the pharmaceutical firm has played.

This study focuses on the protection of trial subjects, who participate in clinical trials for new drug. It takes long time to develop new drugs and the clinical trials are required. Usually, pharmaceutical company, which develop new drug, request a research institution(usually, hospital) to investigate the examination of security and side effects of new drug. The institution recruit trial subject to participate in the trials. The contract for clinical research of investigational new drug is concluded between the pharmaceutical company and the institution. This thesis studies the legal regulations for protection of participants of clinical research for new drug. In this respect the first matter of this study is to seek which relation between pharmaceutical firm and participants of clinical trials. Especially, there is a question which the trial subject is entitled to demand the pharmaceutical company which requested clinical trials the institution to supply the investigational new drug, after the contract for clinical trials had terminated or cancelled. This study take into account the liability of the pharmaceutical company to trial subject. Secondly, it is researched the roles and authority of Institutional Review Board(IRB). IRB is Research Ethics Committee of the institution, in which clinical trials for new drug are conducted. According to the rule of Korea good clinical practice(KGCP), IRB is the mandatory organization which is authorized to approve, secure approval or disapprove the clinical trials for investigational new drug in the institution. The important roles are the review of ethical perspective of trial research and the protection of trial subject. Thirdly, this paper focuses if the participants are to be paid for the participation for clinical research. This is ethical aspect of clinical trials. It is resonable that the participant is reimbursed for expenditure such as travels, and other expenses incurred in participation in trials. It is not allowed that the benefit of clinical trials is paid to trial subject. The payment should not function as financial inducements for participations of trials. Finally, the voluntary consent of the trial subject is required. The institution ought to inform the subject, who would like to participate in trials, and it ought to received informed consent in writing for subject. In this regard, it is matter that trial subject has ability of consent. It is principle that the subject as severely psychogeriatric patient has not ability of consent. However, it is required that not only healthy people but also patients are allowed to take part in clinical trials of new drug, in order to confirm which the investigation new drug is secure. Therefore there are cases, in which the legal representative of subject consent the participation of the trials. In addition, it is very important that the regulations concerning clinical trials of new drug is to be systematically well-modified. The approach of legal and political approach is needed to achieve this purpose.

모든 형태의 임상시험은 시험 자체가 불확실하며, 리스크가 다양하므로 피험자를 보호하기 위한 제도가 완비되어 있어야 한다. 그럼에도 불구하고 현행 임상시험에 관한 법률은 약사법과 의료기기법에서 일정한 규정을 두고 있으나 이는 '의약행정'을 원활하게 수행하기 위한 법목적에 비추어 피험자 보호에는 일정한 한계가 있다. 더 나아가 미성년 피험자를 대상으로 하는 임상시험은 약사법 등에서 직접적인 규정을 두지 않고, '소아를 대상으로 하는 임상시험 평가 가이드라인'이나 '의약품임상시험관리기준' 등에서 일정 부분 규율하고 있으나 이는 법적 효력이 없는 권고사항이라는 점에서 일정한 한계가 있다. 미성년자 대상 임상시험에 대한 법흠결 문제는 인체침습의 정도 면에서 통상적인 의료행위의 경우보다 강한 장기이식법상의 미성년자 취급제도와 기타 외국법상의 미성년자 임상시험 제도를 검토함으로서 입법적 해결이 가능하다고 할 것이다. 그러나 근본적으로는 현행법 체계상 약사법, 의료기기법 기타 가이드라인을 중심으로 이루어지고 있는 임상시험 규율체계를 이른바 "피험자보호법"이라는 법률제정을 통해 해결하는 것이 바람직하다고 본다.

Background and Aims: Herbal drugs and traditional medicines have lately attracted considerable attention by global pharmaceutical corporations because the conventional chemical drugs didn't work well for many chronic diseases or intractable diseases. The government of Korea is also supporting to develop the new drug which is high value added product, and the natural medicine including herbal medicine(or Traditional Korean Medicine) have a significant presence in this field. non-clinical pharmacology/toxicology study and clinical trial are the two major criteria which estimate efficacy and safety for registration of new drugs. All of the pharmaceutical companies producing herbal medicine and the academic and the academic world of Tradition Korean Medicine have the will to develop new herbal drugs, but there are obstacles that they have neither experience nor guideline about clinical trial. Therefore for developing new herbal drugs, it is necessary to research the present conditions and comprehensive systems about clinical trial in Northeast Asian countries China, Taiwan and Japan because they have the common background with Korea in traditional medicine fields. Methods : The present state of clinical trial for herbal medicine in Korea was investigated. And then, those in China, Taiwan, Japan was also investigated. Results and conclusions : There are significant differences among 4 Southeast Asian countries Korea, China, Taiwan and Japan each in present condition, purpose, involved comprehensive system including legislation, and actual operation of clinical trial for traditional medicine.

The purpose of the present study was to evaluate the bioequivalence of two torasemide tablets, Torem tablet (Roche Korea Co., Ltd., Korea, reference drug) and Boryung Torsemide tablet (Boryung Pharmaceutical Co., Ltd., Korea, test drug), according to the guidelines of Korea Food and Drug Administration (KFDA). After adding an internal standard (furosemide) to human serum, serum samples were extracted using 5 mL of ethyl acetate. Compounds were analyzed by reverse-phase HPLC method with UV detection. This method showed linear response over the concentration range of 0.05 ug/mL with correlation coefficient of 0.999. The lower limit of quantitation using 0.5 mL of serum was 0.05 ug/mL which was sensitive enough for pharmacokinetic studies. Twenty-eight healthy male Korean volunteers received each medicine at the torasemide dose of 20 mg in a $2{\times}2$ crossover study. There was a one-week washout period between the doses. Serum concentrations of torasemide were monitored by an HPLC-UV for over a period of 12 hr after the administration. $AUC_{t}$(the area under the serum concentration-time curve from time zero to 12 hr) was calculated by the linear trapezoidal rule method. $C_{max}$ (maximum serum drug concentration) and $T_{max}$ (time to reach $C_{max}$) were compiled from the serum concentration-time data. Analysis of variance was carried out using logarithmically transformed $AUC_{t}$ and $C_{max}$. No significant sequence effect was found for all of the bioavailability parameters indicating that the crossover design was properly performed. The 90% confidence intervals of the $AUC_{t}$ ratio and the $C_{max}$ ratio for Boryung Torsemide/Torem were log 0.97-10g 1.03 and log 0.93log 1.12, respectively. These values were within the acceptable bioequivalence intervals of log 0.80-log 1.25. Thus, the criteria of the KFDA guidelines for the bioequivalence was satisfied, indicating Boryung Torsemide tablet and Torem tablet are bioequivalent.

Backgrounds: With the globalization of drug development, multi-regional clinical trials (MRCTs) have emerged to facilitate rapid availability of medicines to patients worldwide. The present study aimed to has explored attitudes and perceptions towards adopting the Korean MRCT guideline. Methods: An online survey, consisting of 16 questions, classified into two subjects, was administered to stakeholders in Korea. Most quantitative components were measured using the Likert scales. A content analysis of the qualitative components was carried out to identify the keywords in open-ended responses. Results: A total of 94 survey responses were analyzed: 51 participants from pharmaceutical companies, 11 from clinical research organizations, and 21 from clinical trial centers. The content of the guideline was rated as appropriate for clarity, acceptability, and applicability (96.8, 96.8, and 93.6%, respectively). The local environmental impact of the systemic/political, academic/technical, and industrial/economical aspects of the guideline was rated as appropriate at 95.7, 97.9, and 91.5%, respectively. The suggested adoption period was 1~2 years (40, 42.6%). The concept and individuals' domestic circumstances were the key problems affecting the clarity, applicability, and local environmental impact of the guideline. Conclusion: The Korean MRCT guideline was well-developed. Their overall impact on the local environmental impact of MRCTs in Korea was expected to be beneficial, but methods are needed to minimize the negative impacts. The findings of this study can inform the priorities for the future adoption of the guideline in Korea.

Background: Cefcapene pivoxil hydrochloride, is an ester-type oral cephem antibiotic. This study was performed to compare the pharmacokinetics and evaluate the bioequivalence of two cefcapene pivoxil hydrochloride 75 mg formulations. Method: In a randomized $2{\times}2$ crossover study, sixty healthy male volunteers were randomly assigned into two groups. After a single dose of 75 mg cefcapene pivoxil hydrochloride oral administration, blood samples were collected at specific time intervals from 0-12 hours. The plasma concentrations of cefcapene pivoxil hydrochloride were determined by LC-MS/MS. The pharmacokinetic parameters were determined from the plasma concentration-time profiles of both formulations. The pharmacokinetic parameters such as $AUC_{last}$, $AUC_{inf}$ and $C_{max}$, were calculated and the 90% confidence intervals for test/reference ratio for pharmacokinetic parameters were obtained by analysis of variance on logarithmically transformed data. Results: The mean value for $AUC_{last}$ in test and reference drug was $4053.1{\pm}876.5\;ng{\cdot}hr/mL$ and $3595.7{\pm}1029.1\;ng{\cdot}h/mL$, respectively. The mean value for $C_{max}$ in test and reference drug was $1324.9{\pm}321.4$ ng/mL and $1159.1{\pm}335.9$ ng/mL, respectively. The 90% confidence intervals of the $AUC_{last}$ and $C_{max}$ ratio for test drug and reference drug were log 1.09-log1.22 and log 1.09-log1.24, respectively. No adverse events were reported by subjects or found on analysis of vital signs or laboratory tests. Conclusion: This single dose study found that the test and reference products met the regulatory criteria for bioequivalence in these health volunteers. Both formulations were safe and well tolerated in 75 mg of cefcapene pivoxil hydrochloride.
