Safety Study Of Cetuximab Plus Dasatinib (BMS-354825) in Treating Advanced Solid Malignancies

Phase 1

Completed

• Conditions: Malignant Solid Tumour
• Interventions: Drug: Dasatinib (BMS-354825); Drug: Cetuximab (Erbitux, C225)

• Registration Number: NCT00388427
• Lead Sponsor: University of Pittsburgh

Brief Summary

This is an open-label, safety study of cetuximab and differing dose levels of dasatinib in adult patients with advanced solid malignancies. Cetuximab will be administered as an intravenous infusion weekly. Dasatinib will be taken orally, once a day, on a continuous schedule at differing dose levels. The primary objective of this study is to determine the toxicities and the maximum tolerated doses of dasatinib when combined with cetuximab for the treatment of advanced solid tumors.

Detailed Description

This is an open-label, phase I study of cetuximab and differing dose levels of dasatinib in adult patients with advanced solid malignancies. Cetuximab will be administered as an intravenous infusion on a standard dose and schedule (weekly, with the first dose at 400 mg/m2 and all subsequent weekly doses at 250 mg/m2). Dasatinib will be administered orally on a continuous schedule at the following dose levels: 100 mg QD (once a day), 150 mg QD, and 200 mg QD. Three to six patients will be enrolled at each dose level, and the final recommended phase II cohort will be expanded to include up to 12 additional patients. The doses will be escalated in successive cohorts of patients. On cycle 1, dasatinib administration will start one day prior to cetuximab administration. One cycle will be defined as 21 days, and cycles will continue until progression of disease or intolerable toxicities occur. Peripheral blood samples and pharmacokinetic blood samples will be taken on days 0, 1, 15, and 16 of Cycle 1 only. In patients with accessible tumor that give consent, patients will undergo a baseline tumor biopsy and a repeat biopsy after 14-21 days of the first cycle.

Inclusion Criteria

1. Histologically or cytologically confirmed solid malignancy which is recurrent or metastatic or resistant to therapy. Patients w/plan of surgery for recurrent disease post cetuximab/dasatinib are eligible providing that they receive at least 2 cycles of therapy and provide baseline and post-treatment tumor tissue for correlatives.

2. Any number of prior regimens but no prior EGFR or src inhibitors.

3. Age greater or equal to 18 years.

4. ECOG performance status less than or equal to 2 (Karnofsky greater than or equal to 60%).

5. Life expectancy greater than 12 weeks.

6. Patients must have normal organ and marrow function:

   • leukocytes greater than or equal to 3,000/mcL
   • absolute neutrophil count greater than or equal to 1,500/mcL
   • platelets greater than or equal to 100,000/mcL
   • total bilirubin within normal institutional limits
   • AST(SGOT)/ALT(SGPT) less than or equal to 2.5 X institutional upper limit of normal
   • creatinine up to 1.5 x normal institutional limits

7. Ability to understand and the willingness to sign a written informed Consent document.

8. No concomitant medication that are CYP3A4 inducers or potent inhibitors and should not take proton pump inhibitors and H2 antagonists in the first cycle of therapy and should try to avoid taking proton pump inhibitors and H2 antagonists during rest of treatment period.

9. Sexually active women of childbearing potential must use an effective method of birth control during the course of the study, in a manner such that risk of failure is minimized. All WOCBP must have a negative pregnancy test prior to first receiving investigational product.

Exclusion Criteria

1. Chemotherapy or radiotherapy within 3 weeks (6 weeks for nitrosoureas or mitomycin C) prior to entering study or those who have not recovered from adverse events due to agents administered more than 4 weeks earlier.
2. Any other concurrent investigational agents.
3. Patients w/ untreated brain metastases. However, patients who have stable brain disease (should be off corticosteroids) at least 4 weeks after completion of appropriate therapy are eligible.
4. History of allergic reaction to monoclonal antibodies.
5. Inability to swallow oral medications unless patients use a feeding tube.
6. Uncontrolled angina or hypertension or any history of clinically significant ventricular arrhythmias (such as ventricular tachycardia, ventricular fibrillation, or Torsades de pointes).
7. Prolonged QTc interval on pre-entry electrocardiogram (greater than 450 msec) on both the Fridericia and Bazett's correction.
8. Diagnosed or suspected congenital long QT syndrome.
9. Patients currently taking drugs that are generally accepted to have a risk of causing Torsades de Pointes including: quinidine, procainamide, disopyramide, amiodarone, sotalol, ibutilide, dofetilide, erythromycins, clarithromycin, chlorpromazine, haloperidol, mesoridazine, thioridazine, pimozide, cisapride, bepridil, droperidol, methadone, arsenic, chloroquine, domperidone, halofantrine, levomethadyl, pentamidine, sparfloxacin, lidoflazine.
10. Any other uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, or psychiatric illness/social situations that would limit compliance with study requirements.
11. History of significant bleeding disorder unrelated to cancer, including: diagnosed congenital bleeding disorders (e.g., von Willebrand's disease), diagnosed acquired bleeding disorder within one year (e.g., acquired anti-factor VIII antibodies).
12. HIV-positive patients receiving combination antiretroviral therapy.
