The University of Birmingham will co-ordinate a first-rate UK trial to analyse the efficacy of hashish-basically based totally drug Sativex in treating basically the most aggressive form of brain tumours.
The brand new half II trial, to be funded by The Brain Tumour Charity, is to birth at 15 NHS hospitals and follows promising results from a half I peep in 27 patients. The half II trial will assess whether together with Sativex (an oral spray containing cannabinoids THC and CBD) to chemotherapy could extend life for thousands diagnosed with a recurrent glioblastoma, which currently has an lifelike survival of no longer up to 10 months*.
In a half I trial in glioblastomas earlier this year, the drug — already outmoded in treating multiple sclerosis — used to be discovered to be tolerable in combination with chemotherapy, with the aptitude to extend survival.
Whereas the half I peep seen that extra patients had been alive after one year in the Sativex arm when put next to the placebo arm, the peep used to be no longer sufficiently powered to recount survival affect.
The brand new three-year half II trial (called ARISTOCRAT), led by Professor Susan Instant at the University of Leeds and co-ordinated by the Cancer Research UK Scientific Trials Unit at the University of Birmingham, is due to birth up recruiting over 230 patients across all UK countries in early 2022, arena to satisfactory funds being raised.
Having seen its earnings drop by over 25% last year due to the pandemic and been forced to stop its smartly-liked be taught grant funding programme, The Brain Tumour Charity has today launched an charm to raise the £450,000 wanted to launch the trial as soon as that you just could well be ready to assume.
Consultants hope that, can also peaceable the trial expose a success, Sativex could checklist one of the crucial foremost additions to NHS therapy for glioblastoma patients since temozolomide chemotherapy in 2007.
Glioblastomas are basically the most smartly-liked and most aggressive form of brain most cancers, with round 2,200 of us diagnosed each and each year in England alone. They are in most cases hasty-rising and diffuse, with poorly-outlined boundaries and thread-fancy tendrils that extend into other parts of the brain.
As regards to all glioblastomas recur even after intensive therapy together with surgical treatment, radiotherapy and chemotherapy, and lifelike survival is appropriate 12-18 months from first prognosis.
For the duration of the last decade, there used to be important international ardour within both patient and scientific communities about the activity of cannabinoids in brain tumours, with the discover about that cannabinoid-basically based totally products can also no longer simplest reduction attend symptoms but could moreover contain a sure affect on survival.
A lot of pre-clinical laboratory studiescontain urged that cannabinoids THC and CBD can also nick brain tumour cell development and could disrupt the blood present to tumours – on the different hand, to date, clinical proof that they could treat brain tumours has been restricted.
On this new half II trial, researchers will assess whether together with Sativex to the present customary chemotherapy therapy (temozolomide) could offer additional time to are living for adults diagnosed with a recurrence of their glioblastoma after preliminary therapy.
The trial plans to recruit 232 people across as a minimal 15 hospitals: two thirds of the people could be given temozolomide plus Sativex, while one third could be given temozolomide plus placebo.
Sativex, manufactured by GW Pharma, is an oromucosal spray containing 1:1 THC (Delta-9-tetrahydrocannabinol) and CBD (cannabidiol), with the energetic ingredients being absorbed in the liner of the mouth, either below the tongue or within the cheek.
Members could be asked to administer up to 12 sprays per day (or to basically the most dose they’ll tolerate if fewer than 12) of Sativex or placebo oral sprays. Members will then be pleased smartly-liked observe-up together with clinical assessment (every four weeks), blood exams, MRI scans (every eight weeks), and they also’re going to total quality of life questionnaires. This could well moreover be one of the crucial foremost trials to integrate with The Brain Tumour Charity’s app BRIAN.
The trial will measure whether together with Sativex to chemotherapy extends the overall measurement of patients’ lives (overall survival), delays the event of their disease (development-free survival) or improves quality of life.
Professor Pam Kearns, Director of the Cancer Research UK Scientific Trials Unit (CRCTU) at the University of Birmingham, which is co-ordinating the trial, stated: “Our mission at the CRCTU is to translate slicing-edge science and be taught into improved patient care by identifying new therapies that will establish lives. It’s a need to contain that trials fancy this, investigating the role hashish or the chemical substances in it’s going to play treat most cancers, are implemented.”
Major Investigator, Professor Susan Instant, Professor of Scientific Oncology and Neuro-Oncology at the University of Leeds, stated: “The therapy of glioblastomas remains extraordinarily demanding. Even with surgical treatment, radiotherapy and chemotherapy, the majority of these brain tumours re-develop within a year, and unfortunately there are very few strategies for patients once this occurs.
“Cannabinoids contain smartly-described effects in the brain and there used to be rather a lot of ardour of their use across fairly a few cancers for a truly very lengthy time now. Glioblastoma brain tumours were shown to contain receptors to cannabinoids on their cell surfaces, and laboratory studies on glioblastoma cells contain shown these drugs can also gradual tumour development and work particularly smartly when outmoded with temozolomide.
“It’s truly thrilling that we’re now at the level where we can trail a definitive, smartly-designed peep that will expose us the answer to whether these brokers could reduction treat basically the most aggressive form of brain tumour. Having only in the near previous shown that a particular cannabinoid combination given by oral spray could be safely added to temozolomide chemotherapy, we’re truly excited to invent on these findings to assess whether this drug could reduction glioblastoma patients are living longer in a first-rate randomised trial.”
Dr David Jenkinson, Meantime CEO at The Brain Tumour Charity, which is funding the trial, stated: “We hope this trial could pave the formulation for a lengthy-awaited new lifeline that could reduction offer glioblastoma patients treasured additional months to are living and build recollections with their family members.
“With so few treatments available and lifelike survival peaceable so heartbreakingly short, thousands tormented by a glioblastoma in the UK each and each year are in urgent need of present strategies and new hope.
“We know there is very well-known ardour amongst our workforce about the aptitude activity of cannabinoids in treating glioblastomas, and we’re truly excited that this world-first trial here in the UK could reduction trail these answers. The present early-stage findings had been truly promising and we now search forward to realizing whether together with Sativex to chemotherapy could reduction offer life-extension and improved quality of life, which could be a first-rate step forward in our ability to treat this devastating disease.
“However we moreover know that for many, this trial obtained’t reach soon sufficient. Meanwhile, while other hashish-basically based totally products can also reduction alleviate symptoms, there is insufficient proof to counsel their use to reduction treat brain tumours. For any individual fascinated with the use of hashish-basically based totally products or other complementary therapies, it’s a need to contain that you just discuss these with your medical crew first, as they could interact with other treatments comparable to anti-epileptic medicines or steroids.”
Stephen Lee, 62 from Leyland in Lancashire, took half in the half I trial of Sativex in 2015 after his glioblastoma returned following preliminary therapy. Stephen used to be first diagnosed in 2010, appropriate a few months after he had very sadly lost his older brother to the identical disease. Stephen stated: “My prognosis used to be very sudden and used to be one of those days you never forget. Having had to go work early with a excessive headache and a stabbing misfortune in my appropriate sight, my wife insisted that we depart straight to clinic after what my brother had skilled.
“I used to be admitted that very same day, had a scan and that’s once they identified it used to be a brain tumour. I had the operation the next week, and beforehand my wife and I agreed that we wanted to defend sure, to withhold living our lives and to expertise on the different hand vital time we had together.
“I joined the early trial of Sativex in the hope that it could pink meat up my quality of life, but I moreover thought it used to be important to plot so as the chemotherapy and radiotherapy I used to be having had all been trialled by other of us before it could be outmoded safely. I believed it simplest appropriate and appropriate that I adopted of their footsteps and joined a trial to reduction expose a brand new drug which could profit so many of us in due direction with a recurring glioblastoma.
“I took the oral spray 10 cases a day, and it used to be easy as I could interact it wherever we had been going, even while out for dinner. Whereas I don’t know whether I had Sativex or the placebo, since the trial done in 2016, all my MRI scans were particular.
“This new trial is so important as this could well give of us hope that there could be life beyond a glioblastoma prognosis and that there are other treatments being trialled to increase them to are living their lives.”

The preliminary half 1b trial, led by the identical authors, used to be published in the British Journal of Cancer in February 2021. The peep assessed the protection and skill effectiveness of together with Sativex to temozolomide for patients with a newly recurrent glioblastoma (GBM) – discovering it could be tolerated, did no longer appear to interfere with temozolomide therapy and had the aptitude to pink meat up survival. Within the foremost half of the peep, 6 patients obtained a personalised regime of Sativex of up to 12 sprays per day, alongside their temozolomide therapy – and the aspect-effects had been recorded and reviewed. Within the 2d half of the peep, 21 patients had been randomised to rating either Sativex with temozolomide (12 patients) or placebo with temozolomide (9 patients) for a total interval of 12 months. 10 out of 12 (83.3%) patients receiving Sativex had been peaceable alive after one year, when put next to 4 out of 9 (44.4%) patients in the placebo arm.
