SIDCER informed consent form: principles and a developmental guideline.

The quality of informed consent forms (ICFs) remains an issue in clinical research. The lengthy and complicated ICFs currently being used lower research participants' ability to read and understand the information provided therein. In collaboration with the Strategic Initiative for Developing Capacity in Ethical Review (SIDCER), we have developed the SIDCER ICF, which could be of value in improving the quality of the ICFs. The three principles underlying the SIDCER ICF were: (i) an ICF contains all the required regulatory elements; (ii) an ICF provides only such information as is relevant for the subject's decision-making; and (iii) an ICF presents information in a simple format that conveys relevant information to the target population. The SIDCER ICF template, with its instructions, was then structured to assist an investigator in developing an enhanced ICF according to the three principles. The applicability of the SIDCER ICF was tested using a phase I study protocol, and a variety of experts with a special interest in ethics and clinical research were invited to evaluate the comprehensiveness of the three-page ICF for the phase I study. The SIDCER ICF template was refined and finalised in accordance with the results and comments from the experts.

Safety and immune responses following administration of H1N1 live attenuated influenza vaccine in Thais.

BACKGROUND: Emergence and rapid spread of influenza H1N1 virus prompted health authorities to develop a safe and effective influenza vaccine for domestic use. The Thai Government Pharmaceutical Organization (GPO) with technical support from Russia through WHO had prepared a pandemic live attenuated vaccine (PLAIV) using ca-ts attenuated candidate strain A/17/CA/2009/38 (H1N1) for Thais. METHODS: Each participant received two doses of intranasal H1N1 vaccine or placebo 21 days apart. All were followed up at 7, 21, 42 and 60 days after first immunization. Blood was drawn for hemagglutination inhibition (HAI) assay from all participants at days 1, 21, 42, and 60 after first immunization. A subset of 40 participants aged 19-49 years was randomly selected for nasal washing at days 1, 21, 42, and 60 to assess IgA using direct enzyme-linked immunosorbent assay (ELISA) along with serum HAI and microneutralization (MN) assay determination. RESULTS: A total of 363 subjects aged 12-75 years were randomized into 2 groups (271 vaccinees:92 placebos). Almost all AEs were mild to moderate. Local reactions were stuffy nose (22.3%), runny nose (25.1%), scratchy throat (27.2%) and sore throat (19.3%). Systemic reactions included headache (21.7%), myalgia (13.8%), fatigue (16.8%) and postnasal drip (19.9%). On day 60, HAI seroconversion rates for vaccine:placebo group were 30.3:6.0 for ITT and 29.4:5.1 for PP analysis. Children showed highest seroconversion rate at 44, but it decreased to 39.4 when all 3 assays (HAI, MN assay and ELISA) from subgroup analysis were considered. CONCLUSION: The vaccine candidate is safe. The use of more than one assay may be needed for evaluation of immune response because live attenuated vaccines could effectively induce different kinds of responses. Different individuals could also mount different kinds of immune response, even to the same antigen.

Government use licenses in Thailand: The power of evidence, civil movement and political leadership.

This paper attempts to describe and analyse the policy processes that led to the granting and implementation of the government use licenses to enable the import and production of generic versions of medicines patented in Thailand. The decision to grant the series of government use licenses was taken despite much domestic and international controversy. The paper demonstrates that the policy processes leading to the granting of government use licenses are a successful application of the concept of "the triangle that moves the mountain". This is a well-known conceptualisation of a philosophical and strategic approach to public policy advocacy in Thailand, which propounds that the effective bridging of three powers; a.) Knowledge and evidence generated by research and analysis, b.) Civil society movements and public support, and c.) Leadership of policy makers and politicians; in a synergistic "triangle" can move "mountains", meaning the resolution of seemingly insurmountable problems. The paper provides insights into the policy context for the decision and analyses the roles of key actors, their motivations and the policy processes in the country.

Development of influenza vaccine production capacity by the Government Pharmaceutical Organization of Thailand: addressing the threat of an influenza pandemic.

In 2005, a year after highly pathogenic avian influenza outbreaks in Thailand, the Thai Government issued a National Strategy Plan for Pandemic Influenza Preparedness, a major objective of which was the domestic production of seasonal influenza vaccine. It was considered that sustained influenza vaccine production was the best guarantee of a pandemic vaccine in the event of a future pandemic. The Government decided to provide funds to establish an industrial-scale influenza vaccine production plant, and gave responsibility for this challenging project to the Government Pharmaceutical Organization (GPO). In 2007, with support from the World Health Organization (WHO), the GPO started to develop egg-based, trivalent inactivated influenza vaccine (IIV) in a renovated pilot plant. In early 2009, during the second year of the project, the GPO turned its attention to develop a pandemic live attenuated influenza vaccine (PLAIV) against the influenza A (H1N1) virus. By December 2010, the H1N1 PLAIV had successfully completed Phase II clinical trials and was awaiting registration approval from the Thai Food and Drug Administration (TFDA). The GPO has also started to develop an H5N2 PLAIV, which is expected to enter clinical trials in January 2011. The next step in 2011 will be the development and clinical evaluation of seasonal LAIV. To meet the needs of the national seasonal influenza vaccination programme, the GPO aims to produce 2 million doses of trivalent IIV in 2012 and progressively increase production to the maximum annual capacity of 10 million doses. This article relates how influenza vaccine production capacity was developed and how major challenges are being met in an expeditious manner, with strong local and global commitment.

HIV vaccine research and human rights: examples from three countries planning efficacy trials.

The protection of human rights will be critical to the success of HIV vaccine trials throughout the world. A vaccine for HIV remains our best hope to control the global epidemic. In order to launch and sustain useful and successful human trials of HIV vaccines, a partnership between scientists, governments, pharmaceutical companies, and affected communities is essential. This article provides a review of some of the key issues relevant to human rights in the design, testing, and dissemination of HIV vaccines. The article gives specific examples from three countries -- Brazil, Thailand, and the United States -- which may initiate large-scale trials in the near future.
