Since inception, Diaceutics’ focus has been on precision medicine and improving the testing ecosystem to ensure more people with life-threatening illnesses are given the right treatment at the right time. Today, more than 42% of all drugs in late-stage development are dependent upon biomarker testing. However, sub-optimal testing practices mean many patients are missing out on the chance to be put on these potentially life-saving medications. Diaceutics’ services help pharmaceutical companies to pinpoint risks and challenges that can get in the way of effective testing and make it difficult to reach all the patients that need to be on specific drugs. In doing so, Diaceutics is revolutionising patient healthcare by improving the commercial success of precision medicine drugs and the last 12 months have been the company’s most successful yet. Following its IPO on the London Stock Exchange in March, Diaceutics is securing the funding to achieve its vision of better patient testing everywhere. This includes an investment of £1m in the acquisition of 16 million additional patient records per annum. On top of that, the company celebrated its expansion into Asia with the establishment of its Asian HQ in Singapore in January. Diaceutics estimates that there are currently more than 300 targeted oncology drugs in late stage development across the major Asian markets. The company will support the launch of–and access to–precision therapies in China, Japan, Hong Kong, South Korea, Thailand and Taiwan.
