Active clinical trials for "Diphtheria"

The combined pertussis, diphtheria and tetanus vaccine, the first vaccine to be included in the Expanded Programme of Immunization(EPI) of World Health Organization(WHO), has played an important role in the prevention and control of these three infectious diseases. The (diphtheria，tetanus and acellular pertussis combined vaccine，DTaP) vaccine was successfully developed in China in 1993, and its safety and serological effects were confirmed by the observation of human safety, with mild vaccination reactions and good immunization effects.The (Diphtheria-tetanus-component acellular pertussis vaccine, DTcP) vaccine is suitable for immunization against pertussis, diphtheria and tetanus infections in people between 2 and 24 months of age.

A single blind, randomized, comparative, multicentre clinical trial of the immunogenicity and safety of booster immunization with bivalent vaccine against tetanus and diphtheria CLODIVAC (IBSS BIOMED S.A.) and Td-Impfstoff Mérieux (Sanofi Pasteur) in healthy adults.

The goal of this clinical trial is to investigate the safety and tetanus antibody response to a Tdap vaccine in healthy plasma donors. The main question it aims to answer are: Is it safe to give this vaccine multiple times over one year to plasma donors since the package insert for this vaccine indicates that it should administered once every 10 years? What is the tetanus antibody response over time in these donors after receiving the vaccine multiple times during the study? Participants will receive a Tdap vaccination every 3 months ±2 weeks for 12 months (5 vaccinations) with a 6 month follow-up after the last vaccination. After obtaining informed consent and screening for eligibility including plasmapheresis donor eligibility, subjects will have other baseline assessments performed and if eligible, will receive the scheduled vaccinations, will be assessed for adverse events (AEs) and have plasma samples collected for antibody titers each month thereafter for 11 months, and then at 1 and 6 months after the last vaccination. As these subjects are participating in a standard donor plasmapheresis donor program, assessments for donor eligibility and routine plasmapheresis will be performed; however, only the data specifically required to meet the objectives of this study will be collected.

Preeclampsia is a significant medical condition occurring in 3-8% of pregnancies and impacts deleteriously both maternal and fetal health. An important discovery has been made by Dr Craig D Scoville showing that early Tdap vaccinations in pregnancy can reduce the incidence of preeclampsia by more than 50%. A prospective clinical research trial is proposed and urgently needed to validate this finding and thereby make a significant contribution in reducing the incidence of this common and severe complication of pregnancy.

This is an open-label Phase Ia/Ib clinical study of tagraxofusp-erzs, a novel cytokine-drug conjugate that links interleukin-3 with a truncated diphtheria toxin, in combination with gemtuzumab ozogamicin for patients with relapsed/refractory AML. The primary objective of the study is to determine the recommended phase 2 dose (RP2D) of tagraxofusp-erzs in combination with gemtuzumab ozogamicin in this patient population. Then, once RP2D is determined, to determine the safety and tolerability of combination gemtuzumab and tagraxofusp-erzs when administered at the RP2D.

The study will evaluate the safety, immunogenicity，immune persistence and lot-to-lot consistency of Diphtheria,Tetanus and Acellular Pertussis (Three Components) Combined Vaccine, Adsorbed, (DTacP) including 2 parts: PART 1 will evaluate the safety and immunogenicity of DTacP in health infants aged 2 months and 3 months compared with an adsorption Tetanus-diphtheria-acellular Pertussis (DTaP) Vaccine and Diphtheria,tetanus,pertussis(acellular,component),poliomyelitis(inactivated) vaccine(absorbed) and Haemophilus influenzae type b conjugate vaccine (PENTAXIM)，compare the safety and immunogenicity of DTacP with different immunization schedules, and observe the immune persistence. PART 2 will evaluate the lot-to-lot consistency of DTacP in health infants aged 3 months with the 3-dose schedule of 3-4-5 month.

This is a single-center, randomized, active-controlled, parallel-design, double-blind, phase I study to evaluate the safety and immunogenicity of a single dose of APV006 in healthy adults.

Pertussis is an acute respiratory infectious disease caused by Bordetella pertussis, diphtheria is an acute upper respiratory infectious disease caused by Gram-positive Corynebacterium diphtheriae, and tetanus is a highly fatal disease caused by Clostridium tetani infection. Currently, there is no clinical trial registration of Diphtheria, tetanus, and pertussis (DPT) vaccine applicable to ≥6 years of age in China, therefore, the five-component acellular DPT combination vaccine developed by our research has a promising future.

This bridging study is a randomized, double-blind, two arms parallel group, prospective intervention study. The primary objective of this study is to evaluate protectivity of DTP-HB-Hib Vaccine (Bio Farma) using new Hepatitis B bulk (Bio Farma).

The purpose of this study is to evaluate immunogenicity and safety of different doses of candidate hexavalent vaccine in comparison to co-administration of Pentavalent vaccine and Poliomyelitis Vaccine (Inactivated) in separate injections at four weeks after completion of three-dose primary series at 6-10-14 weeks of age when administered to healthy infants and thereby to select the optimal dose of candidate vaccine(Stage 1) and to demonstrate lot-to-lot consistency of three lots of LBVD (Stage 2)
