This study evaluates the drugs Crolibulin (EPC2407) and Cisplatin in adults with advanced solid tumors, focusing on anaplastic thyroid cancer (ATC). It included patients with confirmed cancer and no standard curative treatment. It was a Phase 1/Phase 2 study and has been completed.
The summary above is a plain-language rendering of the official record. The original English title is shown for reference.
Criteria are reproduced from the ClinicalTrials.gov record in the original English. Only the trial team can determine eligibility.
* INCLUSION CRITERIA: Pathologic confirmation of cancer by the Laboratory of Pathology, National Cancer Institute (NCI) Phase I: Diagnosis of recurrent, metastatic or primary unresectable solid tumor that does not have curative standard treatment. Phase II: Diagnosis of recurrent, metastatic or primary unresectable anaplastic thyroid cancer (ATC), including ATC as part of a thyroid carcinoma of another histologic subtype. Measurable disease at presentation with disease measurable by Response Evaluation Criteria in Solid Tumors (RECIST) required in the phase II cohort. A life expectance of at least 3 months as evidenced by Eastern Cooperative Oncology Group (ECOG) performance status 0-1. Age greater than or equal to 18 years Last dose of chemotherapy or experimental therapy more than 4 weeks (6 weeks in the case of nitrosourea) prior to enrollment date; unless the last therapy consisted of an oral agent whose average half life is known to be less than 48 hours in which case only 2 weeks need to have elapsed. Regardless of the therapy, any toxicity greater than Common Terminology Criteria in Adverse Events (CTCAE) grade 1 from previous anti-cancer therapy must have been resolved. Last radiotherapy treatment 4 weeks prior to starting treatment with this protocol with the exception of palliative radiotherapy and there must be sites of measurable disease that did not receive radiation. * Organ and marrow function as defined: * total bilirubin \< 1.5 times the upper limit of reference range (ULRR), unless the patient meets the criteria for Gilbert's Syndrome * alanine aminotransferase (ALT), aspartate aminotransferase (AST) and alkaline phosphatase (ALP) all three \< 2.5 times the ULRR, or \< 5 times the ULRR if judged by the investigator to be related to liver metastases * serum creatinine ULRR or creatinine clearance greater than or equal to 50 mL/minute (calculated by Cockcroft-Gault formula or measured in a timed urine collection) * serum calcium below the CTCAE grade 1 upper limit (11.5mg/dL or 2.9 mmol/L). In cases where the serum calcium is below the normal range, the calcium adjusted for albumin is calculated and substituted for the measured value. * Serum potassium greater than the lower limit of normal (LLN) and \< 5.5 mmol/L. * Serum magnesium greater than the LLN and \< 3.0 mg/dL or 1.23 mmol/L. * absolute neutrophil count greater than or equal to 1000/mm(3) * platelet count (Bullet) 100,000/m m(3) * Prothrombin time (PT) less than or equal to 4 seconds above ULN and partial thromboplastin time (PTT) less than or equal to 10 seconds above ULN. Ability to understand and sign an informed consent document. Provision of informed consent prior to any study-related procedures Negative pregnancy test for women of childbearing potential Ability and willingness to follow the guidelines of the clinical protocol including visits to NCI, Bethesda, Maryland for treatment and follow up visits. Because the effects of chemotherapy on the developing human fetus are potentially harmful, female patients must be one year post-menopausal, surgically sterile, or using an acceptable method of contraception during and continued after the last dose of study medications (oral contraceptives, barrier methods, approved contraceptive implant, long-term injectable contraception, intrauterine device or tubal ligation). Male patients must be surgically sterile or using an acceptable method of contraception during their participation in this study. Contraceptive use will continue for at least two months after the last dose of study medication. EXCLUSION CRITERIA: Patients with cancer potentially curable by surgical excision alone or patients who have not received therapy that might be considered standard and potentially curable. Evidence of severe or uncontrolled systemic disease or any concurrent condition including, but not limited to symptomatic congestive heart failure, unstable angina pectoris, unstable hypertension, seizure disorder, or psychiatric illness which in the Investigators opinion makes it undesirable for the patient to participate in the trial or which would jeopardize compliance with the protocol. Untreated brain metastases (or local treatment of brain metastases within the last three months) due to the poor prognosis of these patients and difficulty ascertaining the cause of neurologic toxicities. During Phase II enrollment: Prior therapy with cisplatin. (Cisplatin will be allowed as prior therapy during Phase I enrollment.) Women who are currently pregnant or breast-feeding, due to the possible adverse effects on the developing fetus and infant. During Phase II enrollment: The presence of a second malignancy within the last 2 years, other than squamous cell carcinoma of the skin or in situ cervical cancer because it will complicate the primary objective of the study. Cancer survivors who have been free of disease for at least two years can be enrolled in this study. Patients with evidence of a bleeding diathesis that cannot be corrected with standard therapy or factor replacement. Any unresolved toxicity greater than CTCAE grade 1 (except alopecia, and certain other unresolved CTCAE Grade 2 toxicities including bone marrow hypocellularity, lymphopenia, infusion-related reaction, infusion site extravasation, injection site reaction, portal vein hypertension, obesity) from previous anti-cancer therapy. Patients with grade 1 neuropathy will be evaluated on a case by case basis for entry into study. Pre-chemotherapy medical conditions will be taken into consideration. Major surgery with incompletely healed surgical incision before starting study therapy. Clinically significant cardiovascular event (e.g. myocardial infarction, superior vena cava syndrome (SVC), New York Heart Association (NYHA) classification of heart disease greater than or equal to 2 (see Appendix C) within 3 months before entry; or presence of cardiac disease that, in the opinion of the Investigator, increases the risk of ventricular arrhythmia. History of arrhythmia (multifocal premature ventricular contractions PVCs), bigeminy, trigeminy, ventricular tachycardia, or uncontrolled atrial fibrillation) which is symptomatic or requires treatment (CTCAE grade 3) or asymptomatic sustained ventricular tachycardia. Atrial fibrillation, controlled on medication is not excluded. Patients with a left ventricular ejection fraction less than the institutional lower limit of normal. History (within the last 6 months) or presence of stroke/cerebrovascular accident. Corrected QT interval (QTc) prolongation with other medications. If the medication can be discontinued and an alternative medication started that does not cause QTc prolongation, the patient would be eligible. If no alternative medication is available and the medication can not be discontinued for medical reasons, then the patient would not be eligible. Congenital long Q wave, T wave (QT) syndrome, or 1st degree relative with unexplained sudden death under 40 years of age. Presence of left bundle branch block (LBBB). QTc with Bazett's correction that is not measurable, or greater than or equal to 480 msec on screening electrocardiogram (ECG). (Note: If a patient has a QTc interval greater than or equal to 480 msec on screening ECG, the screen ECG may be repeated twice (at least 24 hours apart). The average QTc from the three screening ECGs must be \< 480 msec in order for the patient to be eligible for the study). Patients who are receiving a drug that has a risk of QTc prolongation (see Appendix C of the protocol) are excluded if QTc is greater than or equal to 460 msec. Concurrent medication that may cause QTc prolongation or induce Torsades de Pointes: Those medications in Group One of Appendix C of the protocol will not be allowed. Those medications in Group Two of Appendix C of the protocol will be allowed. Crolibulin is a substrate of cytochrome P450 2C8 (CYP2C8), P450 2C9(CYP2C9), P450 2C19 (CYP2C19) and P450 3A4 (CYP3A4). Strong inducers and inhibitors of these enzymes will constitute concomitant medications that are prohibited during the study (See protocol for the complete list). These medications include but are not limited to: for CYP2C8, montelukast and trimethoprim, for CYP2C9, lovastatin and sertraline, for CYP2C19, fluoxetine, ketoconazole, pantoprazole, omeprazole, rabeprazole, and ticlopidine, for CYP3A4, itraconazole, clarithromycin, erythromycin, telithromycin, and verapamil. Hypertension not controlled by medical therapy (systolic blood pressure greater than 150 mm Hg or diastolic blood pressure greater than 100 mm Hg).
