SEB trastuzumab passes first two
pre-clinical tests

The first two facets of pre-clinical trials involving PlantForm’s plant-produced trastuzumab are complete and the results are promising, says Dr. Michael D. McLean, Director of Research.

Safety and toxicology studies designed to assess the maximum tolerated dose of subsequent-entry-biologic (SEB) trastuzumab showed it was tolerated as well as the commercial antibody (Herceptin®) — with no ill effects in mice — at doses that were the equivalent of 25 to 50 times higher than the weekly dosage amount for humans.

Pharmacokinetic studies showed that PlantForm’s SEB trastuzumab and the commercial antibody had similar blood circulatory residence times.
“We’ve produced the antibody, injected it in mice, and shown that our process does not isolate any potentially adverse substances from plants that might cause ill effects,” McLean said. “We’ve also demonstrated that our antibody has similar blood circulatory residence time compared to the commercial antibody.”
In vitro studies, published in the Journal of Agricultural and Food Chemistry, have shown that PlantForm’s SEB trastuzumab effectively inhibits the growth of HER2-positive cancer cells and has the same activity as the commercial antibody.

Efficacy tests on breast cancer tumors in a mouse model are now under way.
