marijuanaBritish medicine company GW Pharmaceuticals has announced that it has achieved confident results on a study using marijuana-derived chemicals to handle glioblastoma, a deadly form of brain cancer.

The study involved 21 patients by recurrent glioblastoma multiforme, or GBM, ~y aggressive form of brain tumour by a median survival rate of a slight under 15 months. Study participants were given a amalgamation of temozolomide, a medication commonly used to refreshment GBM, and GW’s own proprietary cannabinoid product which is composed of one as well as the other tetrahydrocannabinol (or THC) and cannabidiol (CBD), the sum of ~ units prominently active chemicals in marijuana.

Researchers fix that those in the study assemblage who were given temozolomide plus GW’s THC:CBD medicine had an 83 per cent one-year survival rate in comparison to those given proper the temozolomide who had a 53 by means of cent one-year survival rate. Overall, the middle survival rate for those on the THC:CBD physic was more than 550 days compared to 369 days toward the placebo group.

The results inform the promise of cannabis as a of the healing art treatment for cancer, says Susan Short, Professor of Clinical Oncology and Neuro-Oncology at Leeds Institute of Cancer and Pathology at St James’s University Hospital and highest investigator of the study.

“The findings from this well-designed controlled study advise that the addition of a coalition of THC and CBD to patients on dose-intensive temozolomide produced relevant improvements in survival compared by placebo and this is a immaculate signal of potential efficacy,” says Short. “These promising results are of particular interest of the same kind with the pharmacology of the THC:CBD crops appears to be distinct from existing oncology medications and may overture a unique and possibly synergistic option for future glioma treatment.”

The Liberal ruling power in Canada intends to hold virtuous on its promise to legalize the property and growing of marijuana for personal use, and last year, it launched its commencing Access to Cannabis for Medical Purposes Regulations in injunction to improve Canadians’ access to marijuana during the time that a medicine.

The double-impact of THC and CBD seems to exist the key to its effectiveness in treating brain cancer. A 2014 study from the University of London in the UK form in a mould that using THC and CBD cheek by jowl had a much greater ability to check tumour growth related to GBM in mice in relative estimate to trials using either THC or CBD in successi~ their own, which turned out to be seized of no positive effect.

“We remember this is due to the separate pathways that these cannabinoids hit,” declared Dr. Wai Liu, study co-inventor from the University of London’s Department of Oncology, to Medical Daily. “Specifically, THC works via receptors, whilst CBD may not poverty them; consequently, using them together results in a ‘priming’ general intent in tumour cells, making them else sensitive to the ‘cell killing’ movables of irradiation.”

For Canadians, glioblastoma came into the world discussion this past year when Gord Downie, pass singer of the popular rock association, the Tragically Hip, announced that he had been diagnosed with GBM.
