  Purpose

Background:

Anaplastic thyroid cancer (ATC) is one of the most aggressive of all solid tumors; chemotherapy and surgery have had no impact on local control or survival of patients, with a median survival of 3 7 months.

Crolibulin (EPC2407) is a microtubulin inhibitor that has been shown to have direct antitumor effects in vivo and in vitro, destabilizing spindles and inducing apoptosis, resulting in the disruption of neovascular endothelial cells with disruption of blood flow to the tumor. Early clinical studies with combretastatin, from which crolibulin is derived, demonstrated efficacy in a subset of patients with ATC.

Objectives:

The primary objective in the Phase I portion is to assess the safety and tolerability of cisplatin and crolibulin given in a 21-day cycle in dose-seeking cohorts.

We will assess the toxicities of crolibulin coadministered with cisplatin, evaluate dose-limiting toxicities (DLTs) and determine the maximum tolerated dose (MTD) for the combination.

The primary objective in the Phase II portion is to compare the combination crolibulin plus cisplatin versus cisplatin alone in adults with ATC by assessing the duration of progression-free survival (PFS); comparison of the response rates as evaluated by RECIST will be an important secondary objective.

We plan on biochemical and immunohistochemical analysis of several tumor parameters including mitotic index, expression of several proteins including EGFR, VEGFR, BRAF, ERCC1 and TP53. Where sufficient tissue is available we will also perform gene expression analysis, microRNA array analysis, and compare these with 3 -deoxy-3 -[(18)F] fluorothymidine (FLT)-positron emission tomography (PET) and tumor growth rate constant.

Eligibility:

Phase I: adults age 18 and older with unresectable, recurrent or metastatic solid tumors.

Phase II: adults age 18 and older with anaplastic thyroid cancer.

In the phase II portion disease must be evaluable by RECIST.

All patients must have adequate hepatic, renal, and bone marrow function.

Design:

The Phase I component consists of dose-escalation cohorts of three to six patients, in which all patients receive both the study drug crolibulin with cisplatin. The MTD and DLT will be determined based on toxicities during the first three weeks of combined therapy.

The Phase II component will be a randomization study, to either crolibulin with cisplatin or cisplatin monotherapy. Patients randomized to cisplatin alone will have the opportunity the opportunity to cross over to the crolibulin arm in the event of tumor progression.

Drug administration will take place on days 1, 2, and 3 for crolibulin, and on day 1 for cisplatin, on a 21-day cycle.

Maximum number of patients for planned enrollment is 70. During the Phase I portion of the study, dose-seeking cohorts of three to six patients will be enrolled until MTD / DLT is reached for a maximum of three dose cohorts [up to 24 patients if one assumes an expansion cohort to twelve patients at the recommended phase 2 (RP2) dose]. During the randomized Phase II trial comparing the activity of the combination of crolibulin plus cislplatin with cisplatin alone it is estimated that a maximum of 40 patients will be enrolled [1:1 randomization 20 + 20 = 40 patients], and we will allow for 6 extra patients to be enrolled to compensate for a small number of non-evaluable patients.

All patients must have adequate hepatic, renal, and bone marrow function.

Design:

The Phase I component consists of dose-escalation cohorts of three to six patients, in which all patients receive both the study drug crolibulin with cisplatin. The MTD and DLT will be determined based on toxicities during the first three weeks of combined therapy. After a minimum of four cycles of concurrent cisplatin and crolibulin, if the patient is acheiving clinical benefit in the opinion of the investigator but can no longer tolerate cisplatin, the patient may receive crolibulin alone until he or she experiences unacceptable toxicity or progressive disease.

The Phase II component will be a randomization study, to either crolibulin with cisplatin or cisplatin monotherapy. Patients randomized to cisplatin alone will have the opportunity to cross over to the crolibulin arm in the event of tumor progression.

Regardless of the therapy, any toxicity greater than 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.

  • PT less than or equal to 4 seconds above ULN and 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 Investigator s 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.

4. During Phase II enrollment: Prior therapy with cisplatin. (Cisplatin will be allowed as prior therapy during Phase I enrollment.)

5. Women who are currently pregnant or breast-feeding, due to the possible adverse effects on the developing fetus and infant.

6. 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.

7. Patients with evidence of a bleeding diathesis that cannot be corrected with standard therapy or factor replacement.

8. 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. 9. 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.

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 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 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 CYP2C8, CYP2C9, CYP2C19 and 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, itraconzole, 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).
