Active clinical trials for "Mouth Diseases"

Hand, foot, and mouth disease (HFMD) is a common viral illness in infants and children caused by viruses that belong to the enterovirus genus of the picornavirus family. Although most HFMD cases do not result in serious complications, outbreaks of HFMD caused by enterovirus 71 (EV71) can present with a high rate of neurological complications, including meningoencephalitis, pulmonary complications, and can even cause infant death. HFMD caused by EV71 has become a major emerging infectious disease in Asia and the highly pathogenic potential of EV71 clearly requires the attention of world medical community. The development of vaccine against EV71 is active and ongoing in Asian countries now. Several studies have examined the effectiveness of inactivated viral vaccines against EV71 in animal model. A wide range of experimental EV71 vaccine approaches have been studied including heat-inactivated or formaldehyde-inactivated virion, EV71 virus-like particles (VLP) , VP1 recombinant protein ,VP1 DNA vaccine , VP1 peptide-based vaccine targeting the neutralizing domain, bacterial or viral vector expressing VP1, and a Vero cell-adapted live attenuated virus. Furthermore, neutralizing antibodies against EV71 have been suggested as one of the most important factors in prevention of the severe EV71 infection. Recently, an inactivated vaccine(vero cell) against EV71 has been licensed by SFDA in China, this clinical trial phase Ia is armed to evaluate safety and tolerance in Chinese healthy adults and children.

Recently, an inactivated vaccine(vero cell) against EV71 has been licensed by SFDA in China, this clinical trial phase Ib is armed to evaluate safety in Chinese healthy children (from 13 to 60 months old) and infants (from 6 to 12 months old) and also provide the evidences for the EV71 vaccine immunogenicity and the probable immunizing dose.

The primary objective of the study is to assess the effect of RK-0202 versus placebo on the incidence and severity of oral mucositis in subjects receiving radiation therapy for head and neck cancer. Concurrent chemotherapy is not allowed in the study.

This will be a double-blind, randomized, placebo-controlled two-arm parallel groups study of the effect of oral probiotics containing Streptococcus salivarius K12 on oral biofilm, salivation rate, and secretory immunoglobulin A salivary level. The aim of the study is to assess the effect of oral probiotics containing Streptococcus salivarius K12 strain on oral biofilm, unstimulated salivary flow rate, and salivary secretory immunoglobulin A (sIgA) levels.

This study evaluates three batches consistency, immunity duration and safety of inactivated Enterovirus 71(EV-A71) vaccine(vero cell) post-marketing among children aged 6-35months in China.3000 subjects will be recruited in this study, of who 1500 subjects will be randomly assigned in a ratio of 1:1:1 to receive one of the three batches of EV-A71 vaccines manufactured by 40L capacity reactor, other 1500 subjects will be randomly assigned in a ratio of 1:1:1 to receive one of the three batches of EV-A71 vaccines manufactured by 150L capacity reactor. Vaccine wil be administrated according to a two doses of schedule given at day 0 and 28. Sample will be collected at day 0, day 56 and at month 13 after vaccinaiton.

Enterovirus 71 (EV71), a major pathogen causing hand-foot-and-mouth disease (HFMD) worldwide, is a member of the Human Enterovirus species A, family Picornaviridae. Its infection occasionally leads to severe diseases and death, with central nervous system (CNS) damage. An inactivated EV71 vaccine (Human Diploid cell, KMB-17 Cell) has been finished phase I, II and III clinical trials and licensed by CFDA in China at Dec. 3, 2015. Based on the results of clinical trials, the protective efficacy of inactivated EV71 vaccine is 97% against HFMD caused by EV71. The target population is determined to be susceptible children aged 6 to 71 months; this target population is well known as a major global population with strict requirements for safety and efficacy of vaccines in implementing the World Health Organization (WHO) Expanded Program on Immunization (EPI) . Thus, it is necessary and significant to conduct a postmarketing phase IV trial in large populations for long-term observation to evaluate the distinctive effectiveness and to identify potential safety issues . This study is an open-label and controlled postmarketing phase IV trial on children aged 6-71 months who resided in 3 districts of Xiangyang City, Hubei Province, China.

The purpose of this study is to evaluate the efficacy, immunogenicity and safety of EV71 Vaccines in preventing Hand, Foot and Mouth disease caused by EV71 in a total 10,000 healthy infants volunteers aged from 6 to 35months old.

A Phase I clinical trialto evaluate the safety of an Inactivated Enterovirus Type 71 Vaccine in healthy children (3-11y) and infants (6-35m).

The aim of this study is; detection of interleukin(IL)-38, IL-36 gamma(γ) , IL-17 and matrix metalloproteinase(MMP)-9 levels in gingival crevicular fluid (GCF), saliva and serum samples of periodontally healthy, gingivitis and periodontitis patients and the possible correlation between these values and clinical parameters of periodontal diseases. Materials and methods: Samples were obtained from 90 systemically healthy non-smoker individuals with periodontitis (P, n=30), gingivitis(G, n=30) and healthy periodontium (S, n=30). Full-mouth clinical periodontal measurements including probing depth (PD), clinical attachment level (CAL), bleeding on probing (BOP), gingival index (GI) and plaque index (PI) were also recorded. Enzyme-linked immunosorbent assay (ELISA) was used to determine IL-38, IL-36γ, IL-17 and MMP-9 levels in the biological samples.

The purpose of this study is to evaluate the safety and immunogenicity of concomitant administration of EV71 vaccine with recombinant hepatitis B vaccine/Group A meningococcal polysaccharide vaccine.
