Specialists from the College of Leeds will examine whether or not including the drug will prolong the lives of individuals identified with most cancers.
The trial will start enrolling 230 sufferers in 15 hospitals throughout the UK early subsequent yr.

The examine, referred to as ARISTOCRAT, will decide whether or not including Sativex to chemotherapy will prolong sufferers’ lives, sluggish the development of their illness, or enhance their high quality of life.
It will likely be the primary large-scale examine on this planet to make use of the drug to deal with glioblastoma.
Sativex, made by GW Pharma of Cambridge, is sprayed within the mouth and incorporates the cannabinoids THC and CBD.
Laboratory research have proven that these cannabinoids might scale back the expansion of mind tumor cells and disrupt the blood provide to tumors. Nonetheless, medical proof of their effectiveness has to this point been restricted.
A section 1 examine earlier this yr discovered that extra sufferers had been alive after one yr than within the group that acquired placebo therapy.
However the examine – which included 27 sufferers – was too small to substantiate that the therapy will increase survival charges.
The most typical unintended effects reported throughout the Part 1 examine had been fatigue, headache, vomiting, and nausea, which many of the volunteers rated as delicate or reasonable.
Hospitals reminiscent of Leeds Common Infirmary, Man’s and St Thomas’ in London and Queen Elizabeth Hospital in Birmingham might be recruiting contributors for the second section of the examine.

“Cannabinoids have well-described results within the mind and there has lengthy been quite a lot of curiosity of their use in varied cancers.
“Glioblastoma mind tumors have been proven to have receptors for cannabinoids on their cell floor, and laboratory research on glioblastoma cells have proven that these medication sluggish tumor progress and work significantly effectively when used with temozolomide.
“It’s actually thrilling that we at the moment are on the level the place we will do a definitive, well-designed examine that can give us the reply as to whether these compounds might help deal with essentially the most aggressive type of mind most cancers.
“Having not too long ago proven {that a} explicit mixture of cannabinoids, given as an oral spray, could be safely added to temozolomide chemotherapy, we’re excited to construct on these outcomes to find out whether or not in a big randomized trial this drug might assist glioblastoma sufferers dwell longer. “
Dr. David Jenkinson, interim director of the Mind Tumor Charity, mentioned, “We all know that for a while now, sufferers and researchers have been very within the potential exercise of cannabinoids within the therapy of glioblastoma.
“We’re very excited that this world’s first examine right here within the UK might help speed up these responses and we’re grateful to the Leeds Hospitals Charity and so many others around the globe for serving to us make this examine attainable.”
