Another promising Phase II oncology idea goes into the trench in Phase III: GenVec (NASDAQ:GNVC) has been working on a gene-therapy approach ("TNFerade") to induce TNF-alpha expression in tumors. That's not a crazy idea, by any means, although (as with all attempts at gene therapy) getting it to work is extremely tricky.
And so it has proved in this case. It's been a long, hard process finding that out, too. Over the years, the company has looked at TNFerade for metastatic melanoma, soft tissue sarcoma, and other cancers. They announced positive data back in 2001, and had some more encouraging news on pancreatic cancer in 2006 (here's the ASCO abstract on that one). But last night, the company announced that an interim review of the Phase III trial data showed that the therapy was not going to make any endpoint, and the trial was discontinued. Reports are that TNFerade is being abandoned entirely.
This is bad news, of course. I'd very much like gene therapy to turn into a workable mode of treatment, and I'd very much like for people with advanced pancreatic cancer to have something to turn to. (It's truly one of the worst diagnoses in oncology, with a five-year survival rate of around 5%). A lot of new therapeutic ideas have come up short against this disease, and as of yesterday, we can add another one to the list. And we can add another Promising in Phase II / Nothing in Phase III drug to the list, too, the second one this week. . .
