|

| were so small.
|

| get licensed for sale in South Africa, and in the US for the
| veterinary product, but never managed FDA approval. It's a shame.

| actually worked, but they just couldn't seem to make the business
| viable.

| prosecuted for misleading statements to investors about the state
| of US clinical trials, and the legal proceedings became farcical.

| "On March 11, 2009 [Senior VP] Howard Richman pleaded guilty in
| U.S. District Court and admitted he had instructed his lawyers to
| tell a judge he was gravely ill with colon cancer. He also
| admitted to posing as his doctor in a phone call with his lawyer
| so that she would tell the judge that his cancer had spread and
| that he was undergoing chemotherapy."
|
| That guys was sentenced to 3 years in prison. Here's hoping this
| new blood substitute has a happier outcome!
