Intrexon Corporation Initiates Phase 1b Clinical Trial in Advanced Melanoma
News May 12, 2009
Intrexon Corporation announces that it has initiated treatment of the first patient in its Phase 1b clinical trial of INcell-1001/AD-1001 in patients with Stage III/IV melanoma. INcell-1001/AD-1001 is Intrexon’s most advanced immunomodulatory therapy. INcell-1001 is intended to control and enhance the immune-modulating performance of dendritic cells to treat solid tumor cancers.
The trial is an open-label, dose-escalation study evaluating the safety, tolerance, transgene function, pharmacokinetics and immunological effects of intratumoral injection of transduced dendritic cells (INcell-1001). INcell-1001 has been engineered for inducible expression of human Interleukin 12 (hIL-12) using regimented dosing of an orally administered small molecule (AD-1001).
The primary endpoints of the Phase 1b study are the safety and tolerability of INcell-1001 induced by escalating doses of the activator AD-1001. Secondary endpoints include the pharmacodynamics of the AD-1001/INcell-1001 combination, as represented by hIL-12 expression levels, plus anti-tumor activity, as represented by cellular immune responses within the target tumor, draining lymph nodes and peripheral circulation.
Chinese researchers have developed interfacially polymerized porous polymer particles for low- abundance glycopeptide separation. These polymer particles - with hydrophilic-hydrophobic heterostructured nanopores - can separate low-abundance glycopeptides from complex biological samples with high-abundance background molecules efficiently.
