I've raised £15000 to hello..... my father was diagnosed with als(amiotrophic lateral sclerosis) 3 years ago and the medicine that he's been taking is not working

my father is suffering from als for the past 3 years and the treatment that he is received is not working too well ... we read online about a new type of medicine called edaravove( https://thesocialmedwork.com/shop/edaravone-generic) but we lack the funds ... the medicine is not yet approved in Romania and is still in the experimental stage but was approved in other countries... the treatment consists on 13 trials of this medicine ( 60ml per day for 14 days after a break of another 14 days , this is repeated 13 times) he is suffering from diabetes as well and we don't know if this is the cause that the normal treatment is not working .. thank you and hope everyone will be happy and healthy
