When Anita Louise Smith enrolled in an experimental drug trial in 2002 in Colorado, she had a diagnosis of multiple sclerosis but no symptoms and was looking to reduce the chances of being ravaged by the disease. Last year, she died at the age of 46 from an infection linked to the drug.
This tragedy - recounted in an article in the March 4 issue of The Lancet by two Stanford University School of Medicine neurologists - serves as a telling case study of what can go wrong in clinical trials. In their article, Annette Langer-Gould, MD, and Lawrence Steinman, MD, warn of the pitfalls of testing a drug with unknown side effects in patients who would do fine without the drug.
The drug in question is natalizumab, which has the brand name of Tysabri. In November 2004, the U.S. Food and Drug Administration fast-tracked its approval for use in multiple sclerosis patients following promising results seen early in two clinical trials. But within months of the approval, some patients taking the drug had developed a rare infection - progressive multifocal leukoencephalopathy, or PML - and Smith and one other patient had died.

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
