Brief summary
4-Demethyl-4-cholesteryloxycarbonylpenclomedine (DM-CHOC-PEN) is a polychlorinated pyridyl cholesterol carbonate that is lipophilic, electrically neural, crosses the blood brain barrier (BBB), ability to localize in intracranial tumor tissue, lacks neurotoxicity and not transported out of the brain via Pgp (p-glycoprotein) (1). DM-CHOC-PEN has completed Phase I/II trials in humans with primary and secondary tumors involving the brain with success. Complete remissions in both primary astrocytoma and metastatic lung and leukemia malignancies. This trial is open for adult subjects with advanced cancer - brain involvement is required.
Detailed description
The primary goal of this Phase I oncology clinical trial will be to evaluate the safety and use of 4-demethyl-4-cholesteryloxycarbonylpenclomedine (DM-CHOC-PEN) plus radiation, as anticancer therapy for adults with advanced cancer involving the central nervous system (CNS) involvement. DM-CHOC-PEN is a polychlorinated pyridine cholesteryloxycarbonate that crosses the blood brain barrier (BBB), accumulates in CNS tumor tissue in humans and has produced objective responses, with acceptable/reversible hepatic toxicities (in patients with prior liver disease) and no evidence of hematological, renal, neuro-toxicities with improved quality of life and overall survival in adult Phase I/II clinical trials - IND - 68,876. The drug recently received Orphan Drug designation for NSCLC involving the brain. The FDA supports the proposed Phase I clinical trial designed to identify safety, toxicities and an acceptable MTD of the drug in combination with radiation in adult cancers subjects with CNS involvement. Almost 700,000 people in the US are living with tumors involving the CNS or spinal nervous system (SNS) tumors. Trends in CNS tumors have sharply increased since 1989 for individuals with a history of cancer, who appeared to have 'beaten the odds', only to have a reoccurrence from cancer involving the CNS after years of remission; the most common types of cancer in AYA individuals are - from lung, breast, melanoma, and sarcoma malignancies. This group of individuals deserves special attention. A critical component in designing an agent that will cross the protective blood brain barrier (BBB) is that the agent must be readily transported intracerebrally, does not produce local irritation/neurotoxicity and is not recycled back into the general circulation. After IV administration DM-CHOC-PEN readily penetrates the BBB, is not a substrate for the transporter protein P-glycoprotein (P-gp) and has shown anticancer activity in CNS tumors. The effective transport of DM-CHOC-PEN into CNS tumors in adults without neurotoxic behavioral alterations and associated events supports the drug's use in combination with radiation in the treatment of CNS tumors. The observed responses noted in adults with metastatic cancers involving the CNS and cerebellum treated with DM-CHOC-PEN is encouraging. Thus, the drug's unique properties and lack of toxicities noted in the adult studies merits the Phase I trial proposed here in combination with radiation. The specific objectives of this Phase I study will be to: 1. Conduct a Phase I clinical trial with DM-CHOC-PEN plus radiation in adults with advanced cancers involving the central nervous system to document toxicities, define an acceptable maximum tolerated dose (MTD), and identify anticancer activity for the binary treatment DM-CHOC-PEN plus radiation. All data will be communicated through an e-RAP program. This will be accomplished through IND - 68.876. 2. Studying the pharmacokinetic/dynamic profiles of DM-CHOC-PEN and metabolites in adults after being treated with DM-CHOC-PEN and radiation. 3. Analyze data and prepare a Phase II clinical trial or a Designation Orphan Drug application for FDA review.

Inclusion criteria
: Inclusion Criteria will be as follows - * Subjects must have histological proof of a CNS malignancy (primary or metastatic), which has been treated with standard treatments, that may include radiation, and must have measurable lesions. * Subjects must have life expectancy of at least 12 weeks and a Karnofsky performance score: \> 60 % (or a Zubrod performance status of \< 2). * The age limit - a limit of 39 years of age. Gender is not a criterion. * All subjects must be off previous chemo- and/or radiotherapy for at least three (3) weeks prior to entrance into the study and have recovered from any toxic effects induced by such treatment(s); no nitrosourea type drug or ipilumimab treatments are permitted within the last six (6) weeks prior to enrollment. No major surgery within 14 days of enrollment. Subjects may continue to receive anti- estrogen/steroid therapy that has been initiated at least eight weeks prior to enrollment in the study. * Subjects should have adequate bone marrow function defined as a peripheral WBC \>3,000/mm3 with an ANC \>1500/mm3 and a platelet count \>100,000/mm3. * Subjects should have hepatic function (alkaline phosphatase, AST and ALT) \< ULN and renal functions with serum creatinine - \<1.5 x UNL. If a patient has liver metastasis and/or a history of liver disease - they will receive a lower dose of the drug per treatment protocol. * Subjects should not be allergic to eggs or soy beans. * Subjects must be medically, psychologically and neurologically stable and have triplicate baseline ECG's with a mean QTc interval \<500 ms and \>300 ms and neither a history of congenital prolonged or short QT syndrome.
