Details and patient eligibility

About

There is a direct association between cancer and thrombosis (blood clots). The purpose of this study is to determine the best dose of an antithrombotic (prevents blood clots) agent called fondaparinux in non-small cell lung cancer(NSCLC). Patients will also receive chemotherapy.

Full description

This is a single center, open-labeled, single arm phase 1 feasibility study in patients with newly diagnosed stage IV NSCLC. To evaluate the change in the biologic parameters measured, two cohorts of patients will receive altered dosing regimens of fondaparinux starting with the second cycle of chemotherapy. The biologic parameters measured during the first cycle of chemotherapy will serve as a control for each patient. Chemotherapy consists of 3-week cycles of carboplatin and paclitaxel. The absolute maximum length of therapy with fondaparinux will be 3 months, regardless of which cohort the patient is assigned.

This study consists of 2 cohorts:

Cohort 1:

Patients in cohort 1 will receive standard chemotherapy alone during cycle 1. During subsequent cycles (2-4) patients will receive a daily prophylactic dose (day 1 through 21) of fondaparinux. The anticoagulation will continue 21 days after the last course of chemotherapy.

Cohort 2:

Patients in cohort 2 will receive standard chemotherapy alone during cycle 1. During subsequent cycles, the patient will receive a therapeutic weight based dose of fondaparinux for the first 2 days of each chemotherapy cycle followed by a daily prophylactic dose of fondaparinux (day 3 through 21) until the next course of chemotherapy.

Inclusion criteria

• Histologic or cytologic diagnosis of Non-Small Cell Lung Cancer.
• Stage IV Non-Small Cell Lung Cancer.
• Measurable or assessable tumor parameters according to RECIST criteria.
• ECOG Performance Status 0-2.
• Age between 18 and 79 years (in the State of Alabama > 18).
• Adequate hematologic, coagulation, liver and renal function, defined as:
• Absolute neutrophil count (ANC) ≥ 1500/µL
• Platelet count ≥ 100,000/µL
• Serum Glutamic Oxaloacetic Transaminase(SGOT)/Serum Glutamic Pyruvic Transaminase(SGPT) ≤ 2.5 x upper limit of normal or ≤ 5 x upper limit of normal when liver metastases are present
• Total bilirubin value ≤ 1.5 x upper limit of normal
• Serum creatinine value ≤ 1.5 x upper limit of normal
• Normal prothrombin time and partial thromboplastin time
• Fully recovered from any previous surgery (at least 4 weeks since major surgery).
• Must have recovered from prior radiation therapy (at least 3 weeks).
• All participants must agree to practice approved methods of birth control (if applicable). A negative pregnancy test must be documented during the screening period for women of childbearing potential.
• Must provide written informed consent and authorization to use and disclose health information.
• No prior chemotherapy.

Exclusion criteria

• Active bleeding disorder.
• Evidence of hemoptysis. Patients with blood-tinged or blood-streaked sputum will be permitted on study if the hemoptysis amounts to less than 5 mL of blood per episode and less than 10 mL of blood per 24-hour period in the best estimate of the investigator.
• Previous history of Venous Thromboembolism (VTE) within 12 months and requiring active anticoagulation therapy.
• Concurrent cancer chemotherapy, biologic therapy or radiotherapy.
• Administration of any investigational drug within 28 days prior to administration of the current therapy.
• Symptomatic brain metastases; those patients should be treated first with either whole brain radiation therapy or radiosurgery and have stable disease.
• Concurrent serious infection.
• Concomitant severe or uncontrolled underlying medical disease unrelated to the tumor, which is likely to compromise patient safety and affect the outcome of the study.
• History of other malignancy (except non-melanoma skin cancer or carcinoma in situ of the cervix), unless in complete remission and off all therapy for a minimum of 2 years.
• Any evidence or history of hypersensitivity or other contraindications for the drugs used in this trial.
• Psychiatric disorder that prevents patients from providing informed consent or following protocol instructions.
• Pregnant or lactating women.
• Creatinine clearance < 30 mL/min.
• Patient body weight < 50 kg.
