Trial Description


This partially randomized phase I/II trial studies the side effects and the best dose of crolibulin and cisplatin when given together and to see how well they work in treating patients with solid tumors that have come back or spread to other parts of the body and cannot be removed by surgery. Drugs used in chemotherapy, such as crolibulin and cisplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. It is not yet known whether cisplatin is more effective with or without crolibulin in treating solid tumors.

Further Study Information


I. To assess the safety and dose-limiting toxicities (DLTs) of crolibulin given on days 1, 2, and 3 with cisplatin given on day 1 of a 21-day cycle in adults with solid tumors (recurrent, metastatic, or primary unresectable) during dose escalations in order to establish the maximum tolerated doses (MTD) of the drug combination in patients with locally advanced or metastatic cancer, including anaplastic thyroid cancer (ATC). (Phase I)

II. To assess the duration of progression-free survival (PFS, defined as the length of time during and after treatment in which a patient is living with a disease that does not progress by Response Evaluation Criteria in Solid Tumors [RECIST] criteria) and, of somewhat less importance, to determine the tumor response rate (RR) by RECIST criteria in adults with a diagnosis of ATC treated with crolibulin given on days 1, 2, and 3 with cisplatin given on day 1 of a 21-day cycle at the MTD (discovered in Phase I) as compared to the response rate for cisplatin alone given on day 1 of a 21-day cycle. (Phase II)


I. To assess the activity of crolibulin given on days 1, 2, and 3 with cisplatin given on day 1 of a 21-day cycle in adults with cancer by determining: tumor growth rate constant; the incidence of medically necessary interventions (including tracheostomy and gastrostomy) in patients treated with both regimens.

II. Evaluate the mitotic index of tumor specimens using immunohistochemical techniques.

III. Examine by immunohistochemistry or immunoblotting: v-raf murine sarcoma viral oncogene homolog B (BRAF), vascular endothelial growth factor receptor (VEGFR), epidermal growth factor receptor (EGFR), tumor protein p53 (TP53), proliferating cell nuclear antigen (PCNA)/Ki67, thyroglobulin 3 (TG3), excision repair cross-complementing rodent repair deficiency, complementation group 1 (ERCC1), and aurora kinases as possible markers of tumor proliferation; BRAF V600E mutations will be identified by molecular pathology.

IV. The above markers will be correlated with the results of 3'-deoxy-3'-[18F] fluorothymidine (FLT)-positron emission tomography (PET); in a subset of patients pre- and post-treatment studies will be conducted to query whether a reduction in standardized uptake value (SUV) correlates with eventual response to therapy.

V. Evaluate tumor specimen microvascular density using anti-cluster of differentiation (CD)31 immunohistochemical staining.

VI. These findings will be correlated with computed dynamic contrast-enhanced magnetic resonance imaging (DCE MRI) evaluation of tumor perfusion in a subset of patients, to query whether magnetic resonance evidence of perfusion changes by DCE MRI correlate with patient response to therapy and can be used as a predictor of response to therapy with crolibulin and cisplatin.

VII. Evaluate tumor gene expression and micro ribonucleic acid (RNA) profiles and correlate these findings with patient response to treatment with the combination of crolibulin and cisplatin, in the hopes of discovering predictive markers for patient response to therapy and susceptibility of the tumor to other targeted agents.

VIII. Evaluate the effect of therapy on the tumor growth rate constant.

OUTLINE: This is a phase I, dose-escalation study of cisplatin and crolibulin followed by a phase II randomized study.

PHASE I: Patients receive cisplatin intravenously (IV) over 1 hour on day 1 and crolibulin IV over 4 hours on days 1-3. Treatment repeats every 21 days for at least 4 courses in the absence of disease progression or unacceptable toxicity.

PHASE II: Patients are randomized to 1 of 2 treatment arms.

ARM A: Patients receive cisplatin IV over 1 hour on day 1 and crolibulin IV over 4 hours on days 1-3. Treatment repeats every 21 days for at least 4 courses in the absence of disease progression or unacceptable toxicity. Patients may continue to receive crolibulin alone in the absence of disease progression or unacceptable toxicity.

ARM B: Patients receive cisplatin IV over 1 hour on day 1. Treatment repeats every 21 days for at least 4 courses in the absence of disease progression or unacceptable toxicity. Patients developing disease progression may cross over to Arm A.

NOTE: In patients with an objective response and stable disease for > 24 months, treatment with crolibulin repeats every 4 weeks for at least 4 courses in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up every 3-4 weeks for 3-4 months and then periodically thereafter.
