Trial of Bevacizumab and Ixabepilone for Advanced or Metastatic Non-small Cell Lung Cancer (NSCLC)

Phase 2

Terminated

• Conditions: Non-squamous Non-small Cell Lung Cancer
• Interventions: Drug: ixabepilone; Drug: bevacizumab

• Registration Number: NCT01057212
• Lead Sponsor: Providence Health & Services

Brief Summary

This is a non-randomized, open-label, single arm phase II trial of the combination of bevacizumab and ixabepilone in patients with advanced- or metastatic non-squamous NSCLC progressive after first or second-line therapy. The main objective is to evaluate the progression-free survival in patients with advanced or metastatic non-squamous NSCLC being treated with ixabepilone and bevacizumab.

Detailed Description

The first six patients will be enrolled in a lead-in phase of the study utilizing a reduced dose of ixabepilone. Patients will be monitored for safety and toxicity. If the combination is found to be tolerable and feasible, accrual will continue with the full-dose regimen. Toxicity will be monitored in real-time by the study investigators. Should unexpected or increased toxicity be detected, trial accrual will be halted for full analysis.

Bevacizumab will be administered intravenously, 10 mg/kg, every two weeks. Ixabepilone will be administered intravenously, 16 mg/m2, once weekly for 3 of 4 weeks on a 28-day schedule, to the first six patients enrolled. Ixabepilone will be administered intravenously, 20mg/m2, once weekly for 3 of 4 weeks on a 28-day schedule, to the remaining 40 patients enrolled.

Recruitment & Eligibility

• Sex: All
• Target Recruitment: 6

Inclusion Criteria

• Histologic or cytologic diagnosis of advanced or metastatic non-small cell lung cancer (NSCLC), excluding squamous cell-predominant subtype. NSCLC NOS (not otherwise specified) are eligible.

• Patients must have had at least one but no more than two prior systemic chemotherapeutic regimens for metastatic disease. Prior neoadjuvant or adjuvant chemotherapy will not be included in the assessment as a prior chemotherapeutic regimen. Prior therapy with taxanes is allowed. Prior therapy with bevacizumab is allowed.

• Prior chemotherapy or therapy with investigational agents must have been completed at least 3 weeks prior to study enrollment.

• Zubrod performance status of 0 or 1.

• Patients must have measurable or evaluable disease as defined by RECIST.

• Treated brain metastases will be allowed, provided they are asymptomatic. Radiation treatment for brain metastasis must have been completed at least 2 weeks prior to enrollment. Patients must demonstrate stable symptoms and seizure control on a consistent dose of anticonvulsants for at least 2 weeks prior to enrollment. Patients must be off corticosteroids for at least 2 weeks. Treatment for brain metastases may include whole brain radiotherapy (WBRT), radiosurgery (RS; Gamma Knife, KINAC, or equivalent) or a combination as deemed appropriate by the treating physician. Patients with CNS metastases treated by neurosurgical resection or brain biopsy performed within 3 months prior to Day 1 will be excluded.

• Radiation for symptomatic lesions outside the CNS must have been completed at least 2 weeks prior to study enrollment. If measurable disease is within the radiation field, there must be evidence of clear progression (using RECIST criteria) at the time of study enrollment.

• Major surgical procedures must have been performed >28 days prior to study treatment. Portacath placement must have been performed >14 days prior to study treatment. Minor surgical procedures (fine needle aspiration, core biopsy, or mediastinoscopy) must have been performed >7 days prior to study treatment.

• Patients must have normal organ and marrow function as defined below:

  • leukocytes > 3,000/uL
  • absolute neutrophil count > 1,500/uL
  • platelets > 100,000/uL
  • total bilirubin within normal institutional limits
  • AST (SGOT)/ALT (SGPT) < 2.5 X institutional upper limit of normal
  • creatinine < 1.5 mg/dL, OR
  • calculated creatinine clearance > 40 mL/min

• Estimated life expectancy of greater than 12 weeks.

• Patients must be able to sign informed consent.

• Patients must be >18 years of age. Both men and women and members of all races and ethnic groups will be included.

• Patients must either not be of child bearing potential or, if female, have a negative serum pregnancy test within 72 hours prior to Day 1. Patients are considered not of child bearing potential if they are surgically sterile (they have undergone a vasectomy, hysterectomy, bilateral tubal ligation, bilateral oophorectomy) or they are postmenopausal with no menses for at least 12 months. Patients of childbearing potential must be willing to use adequate barrier contraception for the duration of study participation and at least 30 days after study completion.

Exclusion Criteria

• NSCLC with predominant squamous cell histology (mixed tumors will be categorized by the predominant cell type unless small cell elements are present, in which case the patient is ineligible; sputum cytology alone is not acceptable).

• History of hemoptysis (bright red blood of 1/2 teaspoon or more per episode) within 1 month prior to Day 1.

• Known CNS disease, except for treated brain metastasis. Treated brain metastases are defined as having no evidence of progression or hemorrhage after treatment and no ongoing requirement for dexamethasone (within the last two weeks prior to Day 1), as ascertained by clinical examination and brain imaging (MRI or CT) during the screening period. Anticonvulsants (stable dose) are allowed. Treatment for brain metastases may include whole brain radiotherapy (WBRT), radiosurgery (RS; Gamma Knife, LINAC, or equivalent) or a combination as deemed appropriate by the treating physician. Patients with CNS metastases treated by neurosurgical resection or brain biopsy performed within 3 months prior to Day 1 will be excluded.

• Inability to comply with study and/or follow-up procedures.

• An investigational agent within 3 weeks of Day 1.

• Patients with greater than grade 1 neuropathy.

• Pregnant (positive pregnancy test) or lactating.

• Serious concomitant medical disorder, including active infection.

• Active second primary malignancy at the time of study enrollment.

• History of allergic reactions attributed to compounds of similar chemical or biologic composition to ixabepilone or Cremophor EL (polyoxyethylated castor oil).

• Symptomatic peripheral vascular disease.

• Evidence of bleeding diathesis or significant coagulopathy (in the absence of therapeutic anticoagulation).

• Major surgical procedure, open biopsy, or significant traumatic injury within 28 days prior to Day 1 or anticipation of need for major surgical procedure during the course of the study.
