Robust regulatory arrangements provide the foundation for a national method of medicine safety, and for public confidence in medicines. This article focuses on the need to sharpen the regulatory requirements for pharmacovigilance in India. To be effective the remit of drug regulatory authorities needs to go further than the approval of new medicines, to encompass a wider range of issues related to the safety of medicines. In order to achieve their respective objectives pharmacovigilance programs and drug regulatory authorities must be mutually supporting. On one hand, pharmacovigilance programs need to maintain strong links with the drug regulatory authorities to ensure that the latter are well briefed on safety issues in everyday clinical practice, whether these issues are relevant to future regulatory action or concerns that emerge in the public domain. On the other, regulators need to understand the pivotal role that pharmacovigilance plays in ensuring the ongoing safety of medicinal products. Despite global focus on the Development Safety Update Report, Indian regulators are not yet insistent on real-time update of a drug’s cumulative safety profile. Hence, the present article concludes with a strong urge to postulate regulations that create a comprehensive medicine safety system through careful strategic planning that envelope all aspects of pharmacovigilance.
强有力的监管安排为国家药品安全方法和公众对药品的信心提供了基础。本文的重点是印度需要加强药物警戒的监管要求。为了有效,药品监管当局的职权范围需要超越新药的批准,包括与药品安全有关的更广泛的问题。为了实现各自的目标,药物警戒规划和药物监管当局必须相互支持。一方面,药物警戒项目需要与药物监管当局保持密切联系,以确保后者在日常临床实践中充分了解安全问题,无论这些问题是否与未来的监管行动有关,还是与公共领域出现的问题有关。另一方面,监管机构需要了解药物警戒在确保药品持续安全方面发挥的关键作用。尽管全球都在关注开发安全性更新报告,但印度监管机构尚未坚持实时更新药物的累积安全性概况。因此,本文的结论是强烈要求制定法规,通过精心的战略规划,包括药物警戒的各个方面,建立一个全面的药物安全系统。

This study aimed to determine Itraconazole Pharmacokinetics in healthy Indian subjects under fed condition and incurred sample analysis in human plasma by using a validated liquid chromatography tandem mass spectrometric method. A study in healthy human Indian subjects under fed condition was conducted to determine pharmacokinetics of two treatments of Itraconazole 100 mg capsules. Method validation was performed as per USFDA guidelines. Incurred Sample Reanalysis (ISR) was performed by random selection of subject samples. All the method validation parameters were found to be acceptable in terms of accuracy and precision. Results of all stability exercises in human plasma were within acceptable limits. The validated LCMS/MS method was used for sample analysis. A value of 96.7% for Itraconazole and 92.2% for Hydroxy Itraconazole was observed for incurred sample re-analysis. Arithmetic means for Cmax and AUC0→∞ were 103.699, 95.105 ng/ml and 1665.599, 1556.486 ng/ml.h, respectively, for Itraconazole and for Hydroxy itraconazole Cmax and AUC0→∞ were 179.436, 173.037 ng/ml and 4136.456, 4049.746 ng/ml.h, respectively, in treatment 1 and 2. In conclusion, a LCMS/MS method for quantification of Itraconazole and Hydroxy Itraconazole was used for analysis of clinical samples and determination of pharmacokinetic of Itraconazole in a fed study in an Indian population. Incurred sample re-analysis data indicate good acceptance and reproducibility of the method.

In recent years, the growth of clinical research has gone up globally, and countries from Asia are gaining in importance. Being the preferred hub for clinical research because of its young, highly educated work-force, prevalence of all major diseases, and, most importantly, use of English as the medium of communication and documentation making, India is an attractive destination. While enduring growth; few countries have made substantial changes to align with the international standards, wherein the state of affair is still in the process of improvement in India. Also, because of the ever growing hurdles for conducting trials in India, many clinical research sponsors have started searching for other suitable alternatives. Seemingly minor details could have a great impact on the outcome of the trial, not just in terms of time and money, but also the quality and credibility of the data generated. While there are a lot of similarities with that of Western standards of clinical research, there are indeed some key differences as well. Thus, India needs to take the next step up the value ladder to magnetize the global clinical research to outsource, drug discovery and development projects to India, to accelerate timelines and manage complexity. This article attends to various pieces of the same puzzle.
近年来,全球临床研究增长迅速,亚洲国家的重要性日益提高。作为临床研究的首选中心,由于其年轻、受过高等教育的劳动力、所有主要疾病的流行,以及最重要的是,使用英语作为交流和文件制作的媒介,印度是一个有吸引力的目的地。同时持久增长;很少有国家做出实质性的改变以与国际标准保持一致,其中印度的事态仍在改善过程中。此外,由于在印度进行试验的障碍越来越大,许多临床研究赞助商已经开始寻找其他合适的替代方案。看似微不足道的细节可能会对试验结果产生巨大影响,不仅在时间和金钱方面,而且在所生成数据的质量和可信度方面。虽然与西方的临床研究标准有很多相似之处,但也确实存在一些关键的差异。因此,印度需要在价值阶梯上迈出下一步,吸引全球临床研究外包,药物发现和开发项目到印度,以加快时间表和管理复杂性。这篇文章关注同一个谜题的不同部分。

Clinical trials using human subjects are an integral part of the approval of new drugs and biologics. According to Center Watch, 86% of US clinical studies fail to recruit the required number of subjects on time. It is therefore logical that pharmaceutical companies would turn to global outsourcing. Many of these trials are being conducted in developing countries. Accrual in developing countries can be 5–10-times quicker than in the US or Europe. However, clinical trials conducted in other countries differ in many respects. Thus, conducting clinical trials globally raises the concerns of regulatory authorities regarding the transparency, quality, accuracy, and carrying out of these trials following ethical norms. Although clinical research abroad is greatly facilitated by recent efforts to standardize regulatory procedures, and using new technologies has helped to standardize multinational data collection, the issues associated with the globalization of clinical trials still raises concerns about the ethics, adequacy of regulatory supervision of clinical trial, and accuracy and validity of results. This paper examines the impact of the trend being followed globally and presents an analysis of potential ways to capitalize on the associated opportunities while mitigating the challenges in conducting clinical trials globally.
使用人体受试者进行临床试验是新药和生物制剂批准的一个组成部分。根据Center Watch的数据,86%的美国临床研究未能按时招募到所需数量的受试者。因此,制药公司转向全球外包是合乎逻辑的。其中许多试验是在发展中国家进行的。发展中国家的增长速度可能比美国或欧洲快5 - 10倍。然而,在其他国家进行的临床试验在许多方面有所不同。因此,在全球范围内开展临床试验引起了监管当局对透明度、质量、准确性以及按照伦理规范开展这些试验的关注。尽管最近标准化监管程序的努力极大地促进了国外的临床研究,并且使用新技术有助于标准化跨国数据收集,但与临床试验全球化相关的问题仍然引起了对伦理、临床试验监管的充分性以及结果的准确性和有效性的关注。本文探讨了全球正在遵循的趋势的影响,并提出了潜在的方法来利用相关的机会,同时减轻在全球范围内进行临床试验的挑战的分析。

Bioanalytical methods should be reproducible and consistent when applying to clinical sample analysis. Incurred sample reanalyses (confirmatory reanalyses) are performed to support clinical data, and regulatory agencies evaluate the same before approval of bioequivalent products/drugs. A confirmatory reanalysis was demonstrated for metformin after administration of 2/500 mg repaglinide + metformin fixed dose formulation under fasted and fed conditions. The liquid chromatography tandem mass spectrometry (LC-MS/MS) method for determination of metformin in human plasma using metformin-d6as an internal standard has been developed and validated. The ions transitions recorded in multiple reaction monitoring (MRM) were m/z 130.1→60.0 and 136.2→60.0 for metformin and metformin-d6, respectively. The compounds were isolated by solid phase extraction and separated on a C12 reverse phase (Synergi MAX-RP 80A) column, using isocratic mobile phase flow at a flow rate of 0.8 mL/min. No matrix effect was observed within the linearity range of 10.2–1741.8 ng/mL (r2 > 0.99). The acceptable result of confirmatory reanalysis further indicated stability of metformin in the presence of repaglinide. The assay method was found to be highly reproducible and was successfully applied for pharmacokinetic evaluations of metformin in fixed dose combinations with repaglinide.
应用于临床样品分析时,生物分析方法应具有可重复性和一致性。发生的样品再分析(验证性再分析)用于支持临床数据,监管机构在批准生物等效产品/药物之前对其进行评估。在禁食和进食条件下给予2/ 500mg瑞格列奈+二甲双胍固定剂量制剂后,对二甲双胍进行了确证性再分析。建立了以二甲双胍-d6为内标的液相色谱-串联质谱法(LC-MS/MS)测定人血浆中二甲双胍的方法并进行了验证。二甲双胍和二甲双胍-d6的多反应监测(MRM)离子跃迁率分别为m/z 130.1→60.0和136.2→60.0。采用固相萃取法分离化合物,采用C12反相(Synergi MAX-RP 80A)色谱柱分离,流速为0.8 mL/min。在10.2 ~ 1741.8 ng/mL的线性范围内无基质效应(r2 > 0.99)。验证性再分析的可接受结果进一步表明,在存在瑞格列奈时,二甲双胍的稳定性。结果表明,该方法重复性高,可成功应用于二甲双胍与瑞格列奈固定剂量联合用药的药动学评价。

Renovation of the new medicine regulatory process 创新新药监管流程
Pub Date : 2011-11-30 DOI: 10.3109/10601333.2011.607462
S. Crooke
As we near the end of the first decade of the 21st century, it is obvious that the discovery, development, and commercialization of new medicines is a dynamic process that has become vastly more complicated than it was even a few years ago. It is an international process involving companies located in many different countries, clinical trials performed in even more countries and academic contributions from around the world. There are many hundreds of drugs in clinical development. They are representatives of multiple technologies and chemical classes including small molecules, monoclonal antibodies, other proteins, anti-sense oligonucleotides, aptamers, and gene therapy, and, perhaps in the near future, stem cell-based therapeutics. These clinical trials are sponsored by very large multinational pharmaceutical and biotechnology companies with very substantial experience, generic companies, traditional regional companies expanding toward worldwide markets, and biotechnology companies that range in size and competency from very large and experienced to virtual with virtually no experience. The trials are, in fact, often conducted by contract research organizations that again vary widely in size, competency, and experience. All of this is managed by a very uneasy collaboration between the industry, academic medicine, and regulatory agencies. Expectations for the development of new medicines have changed substantially as well. There is greater focus on demonstrating long-term safety. Efficacy trials have become much larger, more complicated and even more multinational. Further, in many therapeutic areas there is increasing demand for long-term outcome studies. These factors contribute to progressively costlier and more time-consuming development cycles that are coupled to longer regulatory review processes, more rapid emergence of competitive products and shorter effective patent lives. These factors, in turn, put more pressure on companies to extract the maximum in sales and profits as rapidly as possible after commercialization, resulting in even greater reliance on direct-to-consumer advertising and efforts to encourage as broad a use of the new medicines as possible. Contemporaneously, food and food processing, nutritionals, vitamins and supplements, cosmetics, and diagnostic industries have also become much more complex. In response, the FDA has grown. It has promulgated new rules and guidelines in virtually every area. It has imposed user fees on the industries it regulates and is buffeted by conflicting demands to facilitate the development of new products, yet reduce risk to unachievable levels. The net result is that no one is satisfied. Patients and patient advocacy groups quite correctly complain about limited progress. The industries contend that the regulatory processes are intrusive, cumbersome, and are applied capriciously. The FDA is criticized consistently and it has been difficult for the agency to recruit and retain outstanding ind
当我们接近21世纪第一个十年的尾声时,很明显,新药的发现、开发和商业化是一个动态的过程,比几年前要复杂得多。这是一个国际性的过程,涉及许多不同国家的公司,在更多的国家进行临床试验,以及来自世界各地的学术贡献。有数百种药物处于临床开发阶段。它们是多种技术和化学类别的代表,包括小分子、单克隆抗体、其他蛋白质、反义寡核苷酸、适体和基因治疗,以及可能在不久的将来以干细胞为基础的治疗。这些临床试验是由具有丰富经验的大型跨国制药和生物技术公司、仿制药公司、向全球市场扩张的传统区域性公司以及规模和能力不等的生物技术公司赞助的,这些生物技术公司从经验丰富的大型生物技术公司到几乎没有经验的虚拟生物技术公司。事实上,这些试验通常是由合同研究组织进行的,这些组织在规模、能力和经验上也有很大的不同。所有这些都是由行业、学术医学和监管机构之间非常不稳定的合作来管理的。对开发新药的期望也发生了重大变化。人们更加注重展示长期安全性。疗效试验已经变得更大、更复杂,甚至更多的跨国试验。此外,在许多治疗领域,对长期结果研究的需求不断增加。这些因素导致开发周期的成本越来越高,时间也越来越长,加上监管审查过程更长,竞争产品出现得更快,有效专利寿命更短。这些因素反过来又给公司施加了更大的压力,要求它们在商业化后尽快获得最大的销售额和利润,导致它们更加依赖直接面向消费者的广告,并努力鼓励尽可能广泛地使用新药。与此同时,食品和食品加工、营养品、维生素和补充剂、化妆品和诊断行业也变得更加复杂。作为回应,FDA扩大了规模。它几乎在每个领域都颁布了新的规则和指导方针。它向其监管的行业征收用户费,并受到促进新产品开发的矛盾要求的冲击,同时将风险降低到无法实现的水平。最终的结果是没有人满意。患者和患者权益组织对进展有限的抱怨是完全正确的。这些行业认为,监管程序是侵扰性的、繁琐的,而且应用起来很反复无常。FDA一直受到批评,该机构很难招募和留住优秀的人才。与所有受监管行业、科学和医学、医疗保健的提供、信息技术和媒体报道所记录的动态变化相比,自1962年立法的上一次重大改革以来,FDA的法律基础和章程几乎没有变化(1-3)。难怪很少有人(如果有的话)对FDA目前的工作感到满意。已经提出了对监管程序进行系统性改革的建议,但尚未实施重大变革(4)。尽管事实上尚未对涉及新药开发的法规进行全面改革,但已经有相当多的新举措值得称赞,并为更重大的变革奠定了一些基础。大多数评论

S. Weinberg, Qiu Fang
This paper is one of a series of country case studies reviewing nations’ regulatory body for the healthcare industry. It reports Israel’s modern regulatory environment and the social background that has shaped its unique agency structure and functionalities. With the Ministry of Health acting as a combination regulatory body, international trade negotiator, and industry supporter, Israel has established a complex partnership relation between government and industry without compromising the regulatory functions of the agency. The result is a focus on protecting Israeli citizen’s health and safety; expanding exports; and assuring the quality of pharmaceutical imports.
本文是一系列国家案例研究之一,回顾了各国对医疗保健行业的监管机构。它报告了以色列的现代监管环境和社会背景,形成了其独特的机构结构和功能。由于卫生部是一个综合监管机构、国际贸易谈判代表和行业支持者,以色列在政府和行业之间建立了复杂的伙伴关系,而不损害该机构的监管职能。其结果是注重保护以色列公民的健康和安全;扩大出口;保证进口药品的质量。
