Objectives: To identify regulatory framework for approval of PET drugs in Korea.
Method: Interview and literature survey.
Results: In Korea Good Manufacturing Practice (GMP) regulation specific to radiopharmaceuticals, including PET (Positron Emission Tomography) drugs, under the Pharmaceutical Affairs Act was issued in August 2014, to be enforced on July 1, 2015, and its guidance was issued in December 2014. The new facilities to be established after July 1 of 2015 have to be compatible with this new regulation and already established facilities have two years grace period until June 30 of 2017. During this period, the regulatory authority will inspect all of the production sites which hold or submit approvals of radiopharmaceuticals. As of September 2015 in Korea, there are 7 commercial companies and 15 hospitals and institutes, which have approvals of PET drugs mainly FDG, and these companies and/or hospitals can supply PET drugs outside institutions. In this article we introduce the Korean regulations of development and approval of radiopharmaceuticals.
Conclusion: The Korean regulatory authorization policy for radiopharmaceuticals are to some extent similar to the policy which the U.S. regulators set as the new regulations of PET drug. It is expected that the situations of production sites in Korea are to be improved through actual discussions among regulators and PET community through the process of actual inspection.

Background: Preclinical testing in animal models is a critical component of the drug discovery process. Over the past three decades hundreds of interventions have demonstrated preclinical efficacy for ameliorating cognitive impairments in animal models; however, none have translated to efficacy in Alzheimer's disease (AD) clinical trials. This lack of translation suggests that there are issues with the animal models employed, the preclinical assays, and poor scientific rigor and reproducibility during execution.

Background: The success of therapeutic options for treatment of Alzheimer's disease (AD) and the growing emphasis for such treatment to commence in the pre-clinical phase makes it necessary to have robust empirical models of clinical disease progression to understand findings from clinical trials, allow clinicians to evaluate effects of new drugs, and to select individuals for future trials. Such models have been developed from relatively small samples, with incomplete data/substantial loss to follow-up. The ADOPIC consortium provides the largest complete AD natural history sample to date.

A distinctive feature of both type 1 and type 2 diabetes is the waning of insulin-secreting beta cells in the pancreas. New methods for direct and specific targeting of the beta cells could provide platforms for delivery of pharmaceutical reagents. Imaging techniques such as Positron Emission Tomography (PET) rely on the efficient and specific delivery of imaging reagents, and could greatly improve our understanding of diabetes etiology as well as providing biomarkers for viable beta-cell mass in tissue, in both pancreas and in islet grafts.

Porcine deltacoronavirus (PDCoV) is a major pathogen causing fatal diarrhea in suckling piglets, and there is currently a lack of effective vaccines and drugs to prevent and control the virus. The nonstructural protein 13 (NSP13) serves as a virus-coded helicase and is considered to be a crucial target for antiviral drugs, making it imperative to investigate the helicase activity of NSP13. In this study, the gene of PDCoV was synthesized and integrated into the prokaryotic expression vector pET-28a to construct the recombinant plasmid pET-28a-NSP13.

Vascular endothelial growth factor receptor-3 (VEGFR-3) plays an indispensable role in lymphangiogenesis. Previous findings suggest that blocking the VEGFR-3 signaling pathway can inhibit lymph node metastasis effectively, thus reducing the incidence of distant metastasis. The development of new VEGFR-3-targeting drugs for early detection and effective treatments is, therefore, urgently required.
