Trial Participants' Responses

Trial participants appeal to Amgen for Compassionate Use of GDNF

Many of the trial participants were devastated both physically and emotionally by the withdrawal of GDNF. They pleaded with Amgen to reinstate the treatments that many found so beneficial. Amgen refused. Trial participants and their family members formed GDNF4Parkinsons – an organization whose goals are to (1) seek compassionate use of GDNF for the trial participants and (2) encourage continued research of GDNF for all people with Parkinson’s. Their personal stories can be found on the website www.gdnf4parkinsons.org. (no longer online)

My Journey with GDNF - Conversations with April, a Phase II Trial Participant

A campaign to support the trial participants and their mission was initiated in October 2004 by grassroots advocates from the Grassroots Connection, Parkinson Pipeline Project and People Living with Parkinson’s. This grassroots effort has been joined by the Parkinson’s Disease Foundation, and individual patient advocates.

Trial participants respond (Fall 2004):  Amgen robbing them of their only hope

According to published reports:

Only weeks after he began receiving GDNF in April 2004, Robert Suthers, 69, noticed dramatic improvement in his PD symptoms. “I could go out for dinner without fear of stumbling. I could write again. I had my life back,” he said.

Then in September, Amgen, halted the clinical trial, and took away Suthers’ access to GDNF. His pumps haven't been refilled since summer, and he feels his symptoms worsening again.

“We'll sign away on the risks for the benefits,” said Suthers, who suffered a seizure following the first surgery, and then a stroke. “I want the drug. We are desperate. It's not fair to take something away that is helping people.” (1)

Steve Kaufman, 50, has had PD for 10 years, and says he “couldn't even hold a nail stable” before he began taking GDNF. The drug allowed him to build new kitchen cabinets and an outdoor deck. After several weeks off the drug, he already feels his stamina slipping and his shaking becoming more pronounced. "I don't think we were given a fair chance," Kaufman said. "It's almost the same thing as a diabetic losing their insulin." (2)

Robert Green agrees. "When I signed on, my wife was lifting me in and out of bed," said Green, diagnosed with Parkinson's 14 years ago at age 36. After the surgery, when the pump was filled with GDNF, he said, "things got progressively easier” and “I was almost self-sustained again. It was a wonderful feeling.” Now, after a few months without the drug, the weakness in his legs is returning, and his wife has to help dress him again.

Another family told Amgen how GDNF allowed their mother to shop, dance and go on vacation for the first time in three years. “GDNF deserves more time, and so does our mother,” they wrote. (2)
