Meanwhile, MAC Clinical Research has a couple of trials looking for men experiencing erectile dysfunction (the payment is a little under £700), and one for people with OCD (£490). All over the country. MAC Clinical Research has clinics in Manchester, Lancashire, Merseyside, south Staffordshire, South Yorkshire, Teesside and West Yorkshire. HMR has a big base in Park Royal, west London, while Trials4us is located in London Bridge, and Parexel is at Northwick Park hospital. The Quotient Sciences trials base is just outside Nottingham, while Labcorp has a clinic in Leeds. FluCamp has facilities in London and Manchester. So are clinical trials safe? Trials4us says this may be the first time the trial medication has been given to humans, "so there may not be any direct knowledge of its side-effect profile". But it adds that the risks involved will have been carefully assessed in animal studies using doses that greatly exceed those given to volunteers. Similarly, Quotient Sciences says you can watch TV or DVDs, play on its Xboxes, read or surf the net and take part in pool tournaments. A man in his 30s from Manchester told us he was paid £730 plus expenses to take part in a trial for a potential treatment for erectile dysfunction. He signed up after seeing an advert on Facebook from MAC Clinical Research. He added: "While I would describe the trial as unusual, the MAC staff brought normality and care; they were all discreet, professional and very knowledgable. The RigiScan device was simple and easy to use. I felt at ease throughout the study. It is great to know that work like this goes on to improve the lives of people suffering." The man said the staff "looked after me really well". He has since returned to take part in another study, and said he may do more in the future. designer bags cyber monday
