Enrollment suspended based upon interim analysis; subjects allowed to stay on study until disease progression.

The primary objective of this Phase II study is to assess the safety, pharmacokinetics and effectiveness of ABT-510 in combination with standard carboplatin/paclitaxel chemotherapy in subjects with stage IIIb or IV NSCLC.

• The subject is able to self-administer or has a caregiver who can reliably administer SC injections.

• The subject must have adequate bone marrow, renal and hepatic function as follows:

  • Bone marrow: White blood cell count (WBC) >= 3,000/mm3; Platelets; >= 100,000/mm3; Hemoglobin >= 9.0 g/dL;
  • Renal function: Serum creatinine <= 2.0 mg/dL;
  • Hepatic function: Bilirubin <= 1.5 mg/dL; AST and ALT <= 1.5 X the upper normal limit (ULN); unless liver metastases are present, then AST and ALT <= 5.0 x ULN.

• The subject has a history of or currently exhibits clinically significant cancer related events of bleeding (e.g., hemoptysis). The subject has a recent history of (within 4 weeks from Study Day 1) or currently exhibits other clinically significant events of bleeding.
• The subject has received investigational therapy within four weeks prior to study drug administration.
