Barry Austin thinks the drug could help him lose weight
One man who weighs 60 stone has told the BBC he would be interested in any drug which was developed.
But Barry Austin said healthy diets and exercise were the real solution to losing weight.
He said: "I've had a lot of problems. I'm immobile with my legs and I'm in and out of hospital.
"The doctors told me I had to lose so much weight. I did lose the weight, but I tried to continue doing it naturally - I'd put it on naturally - but obviously I failed."
He said he was interested in the research into potential drugs.
But Mr Austin, from Solihull, said "I believe there's actually no medical solution. You need to stop eating and start dieting and exercising.
"But I would be interested in anything that could help me lose weight."
He said he had considered having his stomach stapled at one point, but was told he had to lose weight naturally first.
And he said: "Would it really work for properly obese people like myself who need to lose 30 or 40 stone, or would it be helpful for people who just need to lose just a few stone,"
He said the drug could be used in conjunction with a healthy lifestyle.
"You need to be mobile in order exercise and lose the weight in the first place."
