Study of 4-Demethyl-4-cholesteryloxycarbonylpenclome (DM-CHOC-PEN) in Patients With Brain Tumors

Completed · Phase 2

Conditions studied: Primary Brain Tumors, Metastatic Malignant Neoplasm to Brain

In brief

DM-CHOC-PEN is a polychlorinated pyridine cholesteryl carbonate that has demonstrated antineoplastic activities in patients with advanced cancers - melanoma, lung, breast and glioblastoma multiforme (GBM) involving the CNS during a Phase I study. These findings support the preclinical responses seen in mice bearing intracerebrally implanted human breast and GBM tumor xenografts. Toxicity was acceptable - hyperbilirubinemia (in patients with liver disease and/or liver metastasis). No hematological, renal, cardiovascular, behavioral or cognitive impairment/neurotoxicities were noted during the Phase I human trial or in previous pre-clinical studies. The drug is available for use as a soy bean oil/egg yolk lecithin/glycerin water emulsion; the latter continues to be chemically and biologically stable and safe. Patients with advanced lung, breast and melanoma cancers spread to the CNS and primary CNS malignancies will be eligible for enrollment and treatment, providing the required blood and other eligibility requirements are met. The trial will be 2-tiered - patients with liver involvement vs. non-liver involvement will be treated with different doses of the drug. The trial is open and patients are currently being enrolled and treated with the protocol.

Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Patients must have histological proof of a cancer - melanoma, breast, or lung cancer - which has spread to the CNS or glioblastoma (GBM) or other primary malignant neoplasm of the CNS which has been treated with standard treatments, which may include radiation, and must be measurable (RECIST).
• Patients 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 - 18 or older. Gender is not a criterion.
• All patients 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. Patients may continue to receive anti-estrogen/steroid therapy that has been initiated at least eight weeks prior to enrollment in the study.
• Patients 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.
• Patients 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.
• Patients should not be allergic to eggs or soy beans. Patients 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. Patients with a history of cardiac disease must be stable.
• Patients must understand the nature of the study and be willing to sign an informed consent that complies with the investigator/DEKK-TEC policies and approved by the Human Investigation Review Committee. Patients must have CNS involvement - from a malignancy. Lung cancer may be either small cell or non-small cell.

You may not qualify if…

• Patients with concurrent severe and/or uncontrolled medical co-morbidities - including active infections, unstable uncontrolled diabetes, cardiovascular and pulmonary, renal, psychiatric or social conditions that could compromise the safety or compliance of treatment are not eligible.
• Concomitant chemotherapy or radiotherapy is not permitted.
• Pregnant or lactating females are excluded. Women of childbearing age, and their sexual partners, must use an effective contraception program. Males who are having sexual relations with women capable of child bearing must use the barrier birth control while on the study and for 3- months after the last dose of the study drug.
• Patients taking CYP3A4 inducers or inhibitors are not eligible since it is not known whether the study drug is metabolized through this pathway. The following CYP3A4 inhibitors/inducers are not permitted during the trial - the azole antifungal - fluconazole, erythromycin, phenobarbital, verapamil.
• Patients taking the following medications may experience QT/QTc interval prolongation and are not eligible for the trial - most anti-arrhythmia drugs (incl. amiodarone), erythromycin, quinolone antibiotics, ketoconazole, Zithromax, and phenothiazine and will be denied enrollment in the study. The possible interactions of these drugs and DM-CHOC-PEN have not been established. Patients receiving these drug will only be eligible if they discontinue the drugs and have an acceptable ECG.
• Coagulopathies - patients requiring full dose anticoagulation with warfarin are excluded, however, patients stable and on other anticoagulants can be included.
