McMaster University researchers are about to launch Canada's first tuberculosis (TB) vaccine clinical trial with a vaccine totally designed, manufactured and tested within McMaster.
"The exciting thing for McMaster is that this is translational research that has gone from the basic science where the vector has been designed here at McMaster, then manufactured here, with all the pre-clinical studies done at McMaster," said Dr. Fiona Smaill, a professor of medicine and chair of the Department of Pathology and Molecular Medicine.
Development of the vaccine for the landmark trial was led by Zhou Xing, a professor in the Department of Pathology and Molecular Medicine. The vaccine was manufactured in the Robert E. Fitzhenry Vector Laboratory of the Institute of Molecular Medicine and Health on campus, Canada's first university laboratory certified to provide vectors (delivery agents) for use in clinical trials in humans. Most of the pre-clinical testing of the vaccine was undertaken at McMaster.
The phase 1 clinical trial, which has the approval of Health Canada, will begin to recruit 48 healthy volunteers between 18 and 55 years of age in mid-April. Over 12 – 18 months researchers will evaluate the safety of the new vaccine (currently called AdAg85A vaccine) and assess blood samples from vaccinated healthy human volunteers to determine if the vaccine is generating a desired immune response. The trial will be conducted by a team of infectious disease physicians, vaccine manufacturing specialists and immunologists at McMaster.
The announcement of the new TB vaccine trial coincides with World TB Day on Tuesday, March 24, when health authorities and researchers around the world will be raising awareness about the need for new TB vaccines.
Today, TB ranks second only to HIV among infectious killers worldwide, claiming nearly two million lives annually. The disease is evolving faster than therapies with the emergence in recent years of strains that are resistant to every last one of the antibiotic defences.
The McMaster researchers developed the new TB vaccine using a genetically modified adenovirus – a virus responsible for the common cold. After removing a small portion of the gene, they inserted part of the TB gene responsible for immunity. "It is natural ways of making the body use its own immune machinery," said Smaill, a physician and infectious disease specialist.
"Based on all pre-clinical studies carried out on animals, including mice, guinea pigs (who are very prone to TB) and cattle, this vaccine appears to be a very promising candidate vaccine," Xing said.
The vaccine, manufactured to clinical grade standards at McMaster, has passed all the testing required for its use in humans, Smaill said. Along with regulatory approval from Ottawa, the TB vaccine trial has been approved by the research ethics board at McMaster University and Hamilton Health Sciences (HSC).

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
