Biotech firm to start stem cell tests this summer
Jan. 23: The president and CEO of Geron Corp. tells CNBC his company plans to start testing stem cell treatments this summer.
The company gained federal permission this week to inject eight to 10 patients with cells derived from embryonic cells, said Dr. Thomas Okarma, president and CEO of Geron Corp. of Menlo Park, Calif. The patients will be paraplegics, who can use their arms but can’t walk. They will receive a single injection within two weeks of their injury The study is aimed at testing the safety of the procedure, but doctors will also look for signs of improvement like return of sensation or movement in the legs, Marking a new chapter Whatever its outcome, the study will mark a new chapter in the contentious history of embryonic stem cell research in the United States — a field where debate spilled out of the laboratory long ago and into national politics. While some overseas doctors claim to use human embryonic stem cells in their clinics, stem cell experts said they knew of no previous human studies that use such cells. “It’s a milestone and it’s a breakthrough for the field” because Geron passed the safety hurdles for getting federal clearance to launch the study, said Ed Baetge, chief scientific officer of Novocell Inc. His company hopes to begin a similar human study for treating diabetes in a few years. In addition, said spinal cord injury researcher Dr. Wise Young of Rutgers University, “a lot of hope of the spinal cord injury community is riding on this trial.” Embryonic stem cells can develop into any cell of the body, and scientists have long hoped to harness them for creating replacement tissues to treat a variety of diseases. But research has been controversial because embryos must be destroyed to obtain them.

CNBC President Barack Obama has promised to relax the Bush administration’s restrictions on federal financing for such research. But Obama’s ascent to the White House had nothing to do with the U.S. Food and Drug Administration’s granting permission for the new study, Okarma said in a telephone interview Thursday. In fact, the company says, the project involves stem cells that were eligible for federal funding under Bush, although no federal money was used to develop the experimental treatment or to pay for the human study. Other human cells, called adult stem cells, have been tested before in people to treat heart problems, for example. In the Geron study, the injections will be made in the spine at the site of damage. The work will be done in four to seven medical centers around the country, Okarma said. Animal studies suggest that once injected, the cells will mature and repair what is essentially a lack of insulation around damaged nerves, and also pump out substances that nerves need to function and grow. Apart from assessing safety, investigators will hope to see some signs of improvement in the patient, Okarma said. The idea is “not to make somebody … get up and dance the next day,” he said, but rather to provide some level of ability that can be improved by physical therapy. Each patient will receive a low dose of anti-rejection drugs for about two months, because after that time the medications shouldn’t be needed, Okarma said. The study will follow each patient for at least a year. Okarma said he can’t estimate how much such a therapy would cost if it proves effective, but that “this is not going to be a $500,000 price tag. It will be remarkably affordable … in the context of the value it provides.” Click for related content Opinion: Election signals change in bioethics Researchers find easier way to make stem cells Promising stem cell method avoids embryos Evan Snyder, a stem cell researcher at the Burnham Institute for Medical Research in La Jolla, Calif., said scientists in the field will focus chiefly on the study’s results about safety. “The one hope that everybody has is that nothing bad happens,” he said. Geron Corp. has spent at least $100 million on human embryonic stem cell research. Founded in 1992, it does not have any therapies on the market. However, the company is considered the world’s leading embryonic stem cell developer thanks to its claims on several key stem cell technologies. Geron helped finance researchers at the University of Wisconsin who first isolated human embryonic stem cells in 1998. The company has retained exclusive rights on several of those cell types. © 2009 The Associated Press. All rights reserved.
