A Phase 2 Study of CRLX101 in Patients With Advanced Non-Small Cell Lung Cancer

• Assess response rate of CRLX101 compared to BSC [ Time Frame: 12 months ]

• Drug: CRLX101
  CRLX101 is administered at 15mg/m2 IV every other week
• Other: Best Supportive Care

• Platelet count ≥ 100,000 cells/µL without support.
• Adequate hepatic and renal function including the following: Total bilirubin < 2 × ULN, AST or ALT ≤ 2.5 × ULN or ≤ 5 × ULN for patients with liver metastasis, PTT within normal limits, INR ≤ 1.5, Serum Creatinine <1.5 ULN
• At least 4 weeks post any radiotherapy or biological therapy; at least 6 weeks post nitrosoureas therapy.
• Full recovery from diagnostic or therapeutic surgery (i.e., complete wound healing) and at least 30 days have elapsed prior to initial dosing.
