The Institute of Cancer Research (ICR) has helped to develop the new experimental drug, which has entered Phase 1 of safety testing with patients.

The drug, known at the moment as ADZ5363, works by blocking the enzymes that are involved with cancer development and which also cause tumours to become resistant to existing anti-cancer medication.

Medication that prevents the enzyme, Protein Kinase B (PKB), has the potential to treat breast cancerprostate cancer, ovarian cancer, pancreatic cancer and gastric cancers.

The Royal Marsden NHS Foundation Trust and the Christie Hospital NHS Trust in the UK are going to be involved in testing the drug, along with a hospital in the Netherlands.

Scientists and doctors are looking for patients with advanced solid tumours to test the drug, in order to determine the safety, tolerability and initial anti-cancer activity of ADZ5363.

They are also hoping to identify a suitable treatment dose that will be used in later trials of the drug.

The study in being funded by AstraZeneca, a pharmaceutical company which has a major drug and medicine development centre in the UK.

The ICR has been aware of the potential benefits of targeting PKB with a cancer drug for some time, after the crystal structure of the enzyme was indentified.

This detailed 3D understanding of PKB lead to the development of a chemical which could lock on the enzyme and block its cancer causing functions.

Professor Paul Workman, Director of the Cancer Research UK Cancer Therapeutics Unit at the ICR, said: "After many years of research into the enzyme PKB, we are delighted that this inhibitor has reached the patient trial stage."

"This inhibitor is one of a number of new-generation drugs designed to target the genetic defects responsible for causing various cancers, and which have the potential to be used as part of personalized treatments that have greater activity and fewer side-effects than traditional drugs."

Dr Udai Banerji from the ICR and The Royal Marsden Hospital will lead the UK arm of the clinical trial, while Dr Michelle Garrett, from the Cancer Research Technology Limited (CRT), will carry out an investigation into the effects of the drug by testing patients’ blood and tissues for circulating tumour cells.

Dr Banerji says: "We believe that PKB inhibitors could potentially halt the growth of a wide range of cancers, including some that presently have very few treatment options. We are very pleased that patients could soon benefit from this exciting new approach."

The role of tech in public healthcare
We take a look at the role the tech sector plays in public healthcare and hospital systems.

Patient backlogs, aging populations, increasing amounts of data, the COVID-19 pandemic and a workforce experiencing burnout are just some of the challenges the world's hospitals are experiencing. 

Switching to cloud-based digital systems provided by a third party, like  electronic health records (EHR) and e-prescriptions, is an obvious solution. According to Peter Springfield, Cloud Product Manager at Node4, all healthcare providers will need to make this change eventually. "Over time, as legacy technology gets older and the demands placed on it increase, storage systems often can’t keep up" he says. "There comes a point for every healthcare organisation when existing IT simply won’t meet its needs anymore. Instead, healthcare facilities need full, near-instant availability of data to make effective decisions and provide good patient care." 

Patient data must be readily accessible when needed, stored in a regulation-compliant environment, while remaining cost effective. But  how does a paper-based hospital with an overstretched workforce manage this process, while keeping data safe from cyber attacks? By finding a company that can provide the right solution, and working in partnership with them. 

Moving to the cloud

The challenge in healthcare, Springfield says, is that many organisations have siloed pools of data stored in separate repositories. "Often, these systems don’t scale well and don’t have the security protections necessary to meet today’s requirements." 

"Cloud-based storage can scale as high as required. The best cloud vendors also assure high availability and good performance. And because organisations pay only for the capacity they use with cloud-based storage, costs can be lower. As a result, the cloud model also allows healthcare organisations to store and access all data associated with a specific patient, procedure or business unit in one place." 

Another option is to choose Storage as a Service (STaaS). "This is where a third-party provider owns and manages the storage infrastructure, while the healthcare facility can dictate rules on storage, retention and access, along with service level requirements. This structure means that healthcare facilities can access storage on-demand, paying only for the amount they use, without worrying about buying, managing and maintaining physical devices."

Most healthcare providers are choosing a hybrid model, which allows them to use the cloud for everything except the most sensitive data. "Because security and privacy are critical issues for healthcare organisations, the temptation is to keep everything on-premises" Springfield says. "While that can make sense for especially sensitive workloads and applications because it provides tighter controls, it may not be viable for the longer term, as the amount of data that must be managed and stored continues growing." 

Data security

Keeping patient data secure is not just crucial for the patients, but for the healthcare provider too. Ransomware attacks - where a hacker demands money in exchange for not releasing private data - have risen dramatically in recent years, particularly since the COVID-19 pandemic began.  In 2020 alone these rose by 55%, costing almost $21 billion in downtime. 

Healthcare providers' inhouse IT departments may not have the knowledge or the resources needed to combat sophisticated attacks, making it necessary to partner with trusted cybersecurity companies. 

"Healthcare organisations are moving away from doing everything themselves and doing a lot of outsourcing in the cloud" says Terry Ray, Senior Vice President at cybersecurity firm Imperva. "They may have been running Cerner as their electronic medical record system for 15 years for example, but many are now shifting to say, "why am I  running Cerner? Why don't I just pay Cerner to run Cerner? They can enter their data into Cerner's EMR and let it be their problem." 

"The field is getting larger and larger, and the enterprise and scope of what needs to be secured is getting bigger" he adds. "You can't have gaps in security. Organisations must look at everything." 

Virtual healthcare

While security and data storage are two typical areas where public healthcare providers lean on the tech sector, another has been emerging since the pandemic: telehealth. As well as providing access to doctor appointments during the successive lockdowns caused by COVID-19, telemedicine can help deliver healthcare to remote or rural locations that lack health facilities. 

Virtual care solutions are wide-ranging, from Vodafone supplying the connectivity for IoT devices that help elderly people living on remote Greek islands to monitor their diabetes, to TytoCare's portable device that enables doctors to travel to remote regions and examine the heart, lungs, throat, and body temperature of patients using artificial intelligence. 

Busy doctors' surgeries are using digital platforms to help them triage patients - such as eConsult, a digital platform used by the British National Health Service (NHS) in primary and emergency care to assess which patients need to urgently speak to a clinician. 

As with all tech solutions, security and data privacy are vital. "The potential for technology to improve healthcare is almost limitless" Springfield says "The key is remembering where it starts and ends - with data."
