Waltham, MA-based Oxigene’s OXi4503, which is in early clinical trials, and about “five or six others” still in animal testing, White says. The advantage he sees with the Nereus drug is that it appears to enhance the effectiveness of chemotherapy, without adding on any new layers of toxic side effects, as often happens with chemo cocktails. The drug is currently being tested against lung cancer, the leading cancer killer in the U.S.
The second drug, called NPI-0052, requires a little more science explanation. It’s a proteasome inhibitor, derived again from an ocean bacteria called an actinomycete. It’s meant to be a second-generation drug following behind the success of Takeda Pharmaceutical’s bortezomib (Velcade). Drugs in this class are meant to disable the action of enzymes that normally clean up debris in cells. When this ability is disrupted, proteins build up in the tumor cells, sending them into a self-destruct mode called apoptosis. The Nereus drug is thought to block more of the proteasome sites on cells, providing a more effective shutdown, White says. Early trials also suggest the Nereus drug doesn’t cause nerve damage in the hands and feet that limits usage of the Takeda rival, and may work in patients who resist the other treatment. “We don’t get the side effect issue that limits Velcade. Our safety profile is far better,” White says.
That’s a bold thing to say about a competitor that exceeded $1 billion in sales last year, especially when his company’s contender is still in the first of three phases of clinical trials. Nereus, with 25 to 30 employees, has no drugs on the market. By the end of this year, the company expects to have data on its first drug— NPI-2358. —from a trial of 154 patients with non-small-cell lung cancer. Like many companies, Nereus hopes to capture the attention of the leading lights in cancer research at the top two industry conferences of the year, the American Society of Clinical Oncology in late May/early June and the American Society of Hematology in December.
Whatever data is revealed at those meetings will go a long way toward determining if Nereus really can sink or swim (sorry for the ocean pun, but couldn’t resist.) Even in the recession, we’ve seen signs lately in Boston (Vertex Pharmaceuticals) and in Seattle (Seattle Genetics) that companies that can deliver stellar clinical trial results can still be rewarded with financing or partnerships to take them through the most expensive, final phase of development to win FDA approval. Nereus can only hope its data turns out according to plan, and that investors or partners will still be in the mood to finance of its progression to the ultimate proving ground in development—Phase III clinical trials.
