AbstractDESCRIPTION (provided by applicant): The object of the proposed research is to conduct a Phase 1 clinical trial with 4-demethyl-cholesteryloxycarbonylpenclomedine (DM-CHOC-PEN), a carbonate derivative of 4-demethyl-penclomedine (DM-PEN) in patients with ad vanced cancer. The latter is the antitumor active, non-neurotoxic metabolite of penclomedine (PEN). PEN was active in clinical trials but possessed significant neurotoxicity and the trial was cancelled. DM-CHOC-PEN was synthesized as a derivative that coul d cross the blood brain barrier and not be toxic. DM-CHOC-PEN produced complete remissions with long term survival (and no weight loss) vs. intracerebrally (IC) implanted gliomas and breast cancer xenograft models in mice. In contrast DM-PEN did not produc e complete responses in the IC models. DM-CHOC-PEN has completed pre-clinical/toxicology/formulation studies, is being manufactured and will be ready for clinical studies. The product will be administered via a single dose schedule. DM-CHOC-PEN is also act ive in vitro vs. human breast cancer explants and glioma cells, supporting the concept that it does not require prior activation. The product will be administered as an emulsion, the formulation has been stable for gt 2 year at refrigerator storage conditi ons. The package has been reviewed by the FDA - IND 68,876. The specific objectives of this Phase I study will be to: 1) Conduct a Phase 1 evaluation of DM-CHOC-PEN in patients with advanced cancer to determine the maximum tolerated dose (MTD) and characte rize the related principal toxicities. 2) Study the pharmacokinetic and pharmacodynamic profiles of DM-CHOC-PEN in the Phase I clinical trial. 3) Evaluate antitumor activity and electronically store/analyze data. PUBLIC HEALTH RELEVANCE: DM-CHOC-PEN is a n ovel cholesteryl carbonate derivative of PEN that was designed at DEKK-TEC and screened at Southern Research Institute. It has demonstrated impressive abilities to cross the BBB and produce CR and LTS in intracranially implanted U251 and D54 gliomas and MX -1 breast cancer xenograft models. Subsequently, DEKK-TEC has completed the pre-clinical studies, developed a formulation -validated, prepared the IND and the product is ready for a Phase 1 clinical trial. The product will be ready in the Fall '07 for clin ical use as an emulsion. The project has been reviewed by the FDA -IND 68,876.
