GGTI-2418, also known as PTX100, is a synthetic peptidomimetic inhibitor of geranylgeranyltransferase I (GGTase I) that appears to induce apoptosis by downregulating several pivotal oncogenic and tumor survival pathways. In preclinical studies, GGTI-2418 has been shown to cause significant breast tumor regression in ErbB2 transgenic mice model. GGTI-2418 was the first GGTase I inhibitor to enter clinical development in early 2009. Phase I clinical trials early results demonstrated that ~30% of patients with advanced solid tumors had stable disease following GGTI-2418 therapy, the compound was well-tolerated and had minimal toxicity. However, the Phase I trial of GGTI-2418 has been stopped due to its lack of efficacy in patients. In February 2015 Prescient Therapeutics in-licensed the p27 biomarker for use as a companion diagnostic. Patients with low levels of p27 are more likely to respond to GGTI-2418 therapy.

Route of Administration: Intravenous
H-Ras-transformed NIH 3T3 cells were treated with various concentrations of GGTI-2418, and the cell lysates were separated on 12.5% SDS-PAGE. The separated proteins were transferred to nitrocellulose and immunoblotted using an anti-Ras antibody (Y13-258) or an anti-Rap1A antibody (SC-65, Santa Cruz Biotechnology, Santa Cruz, CA). Antibody reactions were visualized using either peroxidase-conjugated goat anti-rat IgG or goat anti-rabbit IgG and an enhanced chemiluminescence detection system.
