The Alzheimer’s Research UK Drug Discovery Alliance

Dr Laura PhippsKirsty MaraisClaire LucasRobin BrisbourneKaty StubbsEd PinchesGlyn Morris

In February 2015 we launched our £30 million Drug Discovery Alliance. The Drug Discovery Alliance is a network of three Institutes at the Universities of Cambridge and Oxford, and University College London. The Alliance is one of the largest coordinated efforts in the world to find new treatments for dementia and today, we’ve announced the drug discovery experts who will lead that search.

What is a Chief Scientific Officer?

Our Chief Scientific Officers (CSOs) will lead scientific progress at each of the Institutes, working with researchers across the UK to zero in on promising new approaches to treat the diseases that cause dementia. Dr John Skidmore, Dr John Davis and Prof Paul Whiting, at Cambridge, Oxford and UCL respectively, have over half a century of drug discovery experience between them. They will guide the work of their individual Institutes, but also collaborate to ensure efforts are coordinated and that their teams are pursuing many different approaches.

What research will take place in the Drug Discovery Alliance?

There hasn’t been a new treatment licensed for Alzheimer’s since 2002 and many people with other causes of dementia have no specific treatments available to them. We’ve discussed the failure rate of clinical trials for Alzheimer’s disease in the past, and our CSOs will now take an innovative approach to re-energise the search for new treatments.

They’ll test approaches previously unexplored for dementia by the pharmaceutical industry and this means searching far and wide for the best ideas from the research community. They’re seeking out targets. A target is a protein or pathway that plays a role in the course of the disease and that we can modify with drugs to help halt damage in the brain. Sometimes a protein may be a lynchpin in a biological cascade that leads to nerve cell damage. But other times, a protein may just be an innocent bystander in the huge number of biological events that are triggered in the disease. Our CSOs have the challenge of selecting the most promising targets to pursue and building drug discovery projects around them.

Drug discovery involves many different steps and unites expertise from across biology and chemistry. The biologists working in our Drug Discovery Alliance will study new targets in depth, to confirm the role they play in the diseases that cause dementia. They’ll also design and create biological tests to measure the impact of modifying these targets with experimental drugs in the laboratory.

Finding the perfect match

It’s the chemist’s job to create these experimental drugs. Unfortunately, drug design isn’t as simple as making a key that fits a lock. Chemists have to make thousands of subtly different chemical compounds that fit the target and alter its function, in order to find the perfect match with all the right qualities.

These chemical compounds will enter what’s called a screening cascade. A screening cascade is essentially a series of tests that the chemical compounds must pass to carr on through the development process. Not only must the chemical compound bind to the target, but it must change the way the target works, have an impact on the hallmark features of the disease and be safe, amongst many other things. A tall order, and part of the reason drug discovery is such a challenge. When a chemical compound fails a test then that tells the scientist about what was wrong with the compound and what properties need to be improved.

Eventually, a compound will make it all the way through the cascade and this will be the compound that scientists develop further to make a drug. It’s called the ‘lead compound’ and it now has to go through further development and tests in animals before it can enter clinical trials. These tests are designed to see how safe the experimental drug is in a living organism and how well it is absorbed and broken down in the body.

The Drug Discovery Alliance will focus on the early stages of drug development, creating lead compounds and then working with industrial partners to push these promising leads through further development towards clinical testing.

Dementia is a huge medical challenge and we’ll only beat it with big research ambitions. We’re excited to welcome our new Chief Scientific Officers on board to capitalise on the innovative ideas and discoveries from across the research community and translate them quickly into potential new treatments for people with dementia.

    It must be tedious to the point of demoralising to go through thousands in a cascade of chemicals until maybe a year or two later one is found to be binding and doing good.
    Our instant society now wants “next day delivery”.

    Knowing how I am with multi chronic conditions & Late parents Father a pharmacist & Mother had it so severely her cognition & mobiltty/function had completely gone .To point of she couldn’t understand speak swallow with food pureed .The NHS funded her as normal knowing it took 3 people to steady her on the loo & had to be hoisted everywhere.Because she was not a problem they overlooked her thinking she could understand .i HAVE SEEN THE NOTES??!!
    Anyhow I have found acupuncture extremely beneficial especially the latest at my new surgery in Gloucestershire .He is only one who can think freely & condition effects heat & brain you need flexibility .
    Growing up in the 60s this was often the norm alongside western medicine.I t has helped my immunity to infection as suffered from most childhood diseases including bronchopneumonia measles, chickenpox , scarletina ,utis, & pyuria/sepsis/antibiotic connection There are also hormonal imbalances & insulin diabetic connection genetic through the males.As well as heart , stroke & rheumatic & cancer weakness.My Mother too had a autoimmune condsitions like dermatitus & polymyalgia rheumatica & possibly [ GCA??} Sjongrens?

    When I had heart failure symptons due to no assistance for breathing/function problems ie: disability spina bifida re: utis acute 3 weekly & IBS since urogenic bladder & reflux found Research Royal Free 1969 now MI 10 yrs ago with PAH found last yr re: diuretics not found in tests so not treated classic symptons same with Reveal device.Oedema untreated for 3yrs become lio-lymphoedema even though I funded adomnoplast abroad plusgastric band & gall bladder out.
    Still NHS discrimiating re sedation as pulse drops to 80 yet still no provision for restorative calling cosmetic & NHS dentists & doctors not wanting as too risky

    re: Acupuncture
    When haematuria found in my urine sample 3 weekly the Prof could do nothing .So on research & experience decided to try a steady bout of chinese acupuncture .When I had MI a year later I had to be resuscitated 3x with an angioplasty .They said I was lucky. Lucky or was it Acupuncture..I then went to the Chinese Acupuncture Research next to the Prof for urodynamics as my heart felt like an old boot had sacral cranial surgery .I had this again with the spasms giving excrutiating spinal spasms & antibiotics[ uti] relieving .The CPAP machine & Reveal Device for comotosing daily on eating are also ineffective .Is this it . Am I a financial pawn as the Specialist who went to for consciousness research runs a sleep clinic??!!

    Steroid injections have helped spinal spasicity which comes back when utis not appropriately managed .I had to pay for a very expensive MRI .Why do private specialists request NHS referral with you asking for it .Is it a scam as I have paid up trusting him but don’t want his Sleep Clinic.
