Hypothesis

The study evaluates the safety and pharmacokinetics of a novel human recombinant glucocerebrosidase enzyme expressed in transformed plant cells.

Conclusion

The study found that the plant-derived glucocerebrosidase enzyme is safe and well-tolerated in both primates and human volunteers.

Supporting Evidence

  • The enzyme was well tolerated with no serious adverse events reported.
  • No anti-prGCD antibodies were detected in the volunteers.
  • The pharmacokinetic profile showed a prolonged half-life compared to the commercial enzyme.

Takeaway

Researchers tested a new medicine made from plants to help people with a disease called Gaucher disease, and it was found to be safe.

Methodology

The study involved safety and pharmacokinetics assessments in primates and a Phase I clinical trial with healthy volunteers receiving escalating doses of the enzyme.

Limitations

The study was conducted with a small number of participants and for a short duration.

Participant Demographics

Six healthy volunteers, 3 males and 3 females, aged 19-36, all Caucasian.
