Ixabepilone in Combination With Carboplatin in Patients With Non-small Cell Lung Cancer

DLT is defined as any of the following: Common Terminology Criteria (CTC), Version 3, Grade(Gr) 4 neutropenia (absolute neutrophil count <500 cells/mm^3) for at least 5 days or febrile neutropenia; Gr 4 thrombocytopenia (<25,000 cells/mm^3 or bleeding needing platelet transfusion); Gr 3 or 4 nausea, vomiting, or diarrhea, despite medical intervention; any other drug-related Gr 3 or 4 nonhematologic toxicity, except Gr 3 injection site reaction, fatigue/asthenia, transient arthralgia/myalgia, or transient electrolytes abnormal. Gr 1=Mild; Gr 2=Moderate; Gr 3=Severe; Gr 4=Life-threatening.

The MTD was defined as the highest dose evaluated for which less than one sixth of patients experience a DLT in Cycle 1. The recommended phase 2 dose is the MTD defined in Cycle 1, with consideration given to chronic cumulative toxicity occurring at later cycles.

An SAE is any untoward medical event that at any dose: results in death, persistent or significant disability/incapacity, or drug dependency or abuse; is life-threatening, an important medical event, or a congenital anomaly/birth defect; or requires inpatient hospitalization or prolongs existing hospitalization. An AE is any new untoward medical occurrence or worsening of a preexisting medical condition that does not necessarily have a causal relationship with this treatment. Treatment-related comprises certainly, probably, and possibly related and of unknown relationship to study drug.

An AE is defined as any new untoward medical occurrence or worsening of a preexisting medical condition that does not necessarily have a causal relationship with treatment. AEs graded according to CTC, Version 3.0. Gr 1=Mild; Gr 2=Moderate; Gr 3=Severe; Gr 4=Life-threatening. Treatment-related comprises certainly, probably, and possibly related and of unknown relationship to study drug.

LLN=lower level of normal; ULN=upper level of normal. Hemoglobin (g/dL; LLN=11.3; ULN=14.9); leukocytes (*10^3 c/uL; LLN=4.1; ULN=6.1); lymphocytes (*10^3 c/uL); neutrophils (absolute), neutrophils + bands (*10^3 c/uL); platelet count (*10^9 c/L; LLN=131; ULN=365)

Appendix 7.1.2

ULN=upper limit of normal; LLN=lower limit of normal. Alkaline phosphatase=ALP(LLN=115; ULN=359) (U/L); alanine aminotransferase=ALT (LLN=8; ULN=42)(U/L); aspartate aminotransferase=AST (LLN=13; ULN=33) (U/L); albumin (LLN=3.7; ULN=5.2)(g/dL); bilirubin (LLN=0.3; ULN=1.2)(mg/dL); calcium (LLN=8.7; ULN=10.3)(mg/dL); creatinine (LLN=0.6; ULN=1.1)(mg/dL); potassium (LLN=3.6; ULN=4.9) (mEq/L); sodium (LLN=138; ULN=146) (mEq/L)

Toxicities graded according to CTC, Version 3. Protein Gr 1: <1.0 g/24 hrs (1+); Gr 2: 1.0 to 3.4 g/24 hrs (2+ to 3+ ); Gr 3: >=3.5 g/24 hrs (4+); Gr 4: Nephrotic syndrome. Note: + = qualitative measure of urine chemistry.

Blood pressure and heart rate obtained before ixabepilone infusion, every 1 hour during and at the end of ixabepilone infusion, and at the end of carboplatin infusion in Cycle 1. For subsequent cycles, vital signs obtained before ixabepilone infusion, at the end of ixabepilone infusion, and at the end of carboplatin infusion. Any new or worsening clinically significant changes since last entry were recorded as appropriate AE or SAE.

Participants weighed same day as serum chemistry tests. Body surface area recalculated only if body weight changes >10%. ECOG criteria used to assess disease progression and affects on daily living abilities and to determine appropriate treatment and prognosis. Grade 1=Restricted physical activity but ambulatory and capable of light work; Grade 2=Ambulatory, capable of self care, but unable to carry out any work activities; Grade 3=Capable of limited self care, confined to bed or chair 50% or more of waking hours; Grade 4=Completely disabled, totally confined to bed or chair.

Tumor response was assessed using the RECIST assessment: Complete response (CR)=Disappearance of all clinical and radiologic evidence of target lesions; Partial response (PR)=At least 30% reduction in the sum of the longest diameters of all target lesions; Progressive disease (PD)=At least 20% increase in the sum of the longest diameters of all target lesions; Stable disease (SD)=Neither PR nor PD criteria were met.
