SOMATOGEN PLANS IND FOR HEMOGLOBINSomatogen Inc. of Boulder, Colo., plans to submit anInvestigational New Drug application this year to start clinicaltesting of a genetically engineered human hemoglobin.

Construction is nearly completed on a production facility tosupply hemoglobin tfor clinical testing, Charles Scoggins,president and chief executive officer of the privately heldcompany, told the Hambrecht & Quist Conference in LifeSciences in San Francisco on Wednesday.

The blood substitutes market, which some analysts estimatecould grow to $3 billion worldwide, has tempted manycorporate players. But the technical difficulties of creating asafe, stable compound with good oxygen-carrying capacity hasstymied researchers, according to Scoggins.

Somatogen faced the challenge by developing a recombinantform of human hemoglobin. Scoggins said that it remains stablein the body, delivers a greater proportion of oxygen to tissuesthan native hemoglobin, can be manufactured with good yieldin large amounts, and shows promise of attaining a shelf life ofone year at room temperatures.


Patients with late-stage melanoma who were treated in PhaseII trials of Ribi Immunochem Research Inc.'s melanomatherapeutic showed significantly higher survival rates, thecompany reported Wednesday.

Ribi (NASDAQ:RIBI) of Hamilton, Mont., is talking with apotential co-marketing partner, said Robert Ivy, Ribi'spresident and chief executive officer.

In Phase I/II studies of 18 surgery patients at high risk fordeveloping septic shock, Ribi's MPL prophylacticimmunostimulant reduced infection rates by 40 percent andalso reduced the length of hospital stays. Ribi said that MPLblocks the release of septic shock-inducing cytokines byendotoxin. It also appears to reduce tissue damage in animalheart attack models, possibly by blocking the release ofoxygen-free radicals by neutrophils. More animal studies areplanned.

Ribi has about $5.3 million in cash and a burn rate of about$2.3 million, Ivy said. Ribi's goals for 1991 are to find acorporate partner, license its adjuvant technology to vaccinecompanies and raise some private funding, he said.
