Summary

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 Response Evaluation Criteria in Solid Tumors (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 epidermal growth factor receptor (EGFR), vascular endothelial growth factor receptor (VEGFR), BRAF, excision repair cross-complementation group 1 (ERCC1) and tumor protein p53 (TP53). Where sufficient tissue is available we will also perform gene expression analysis, micro ribonucleic acid (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 cisplatin 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.

Eligibility Criteria

  • 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, o
