A Novel Erythropoiesis Stimulating Protein (NESP; Darbopoetin Alfa) for the Treatment of Anemia in Lung Cancer Patients Receiving Multi-cycle Platinum-Containing Chemotherapy

Study Overview
=================
Brief Summary
-----------------
The primary objective of this study was to compare the effectiveness of darbopoetin alfa to placebo in the treatment of anemia in adults with lung cancer receiving multicycle platinum-containing chemotherapy, by assessing the percentage of participants who received red blood cell (RBC) transfusions during weeks 5-12 inclusive.

Eligibility Criteria
-----------------
Inclusion Criteria: Lung cancer (either small cell [SCLC] or non-small cell [NSCLC]) At least 12 additional weeks of platinum containing cyclic chemotherapy planned regardless of cycle length Anemia (hemoglobin ≤ 11.0 g/dL) as assessed by a local or central laboratory result within 7 days before study day 1 (the first scheduled day of on-study chemotherapy and the first day of study drug administration) Life expectancy of at least 6 months, and an Eastern Cooperative Oncology Group (ECOG) performance status of 0, 1, or 2. Anemia predominantly due to the cancer or chemotherapy (i.e.. serum folate ≥ 4.5 nmol/L (≥ 2.0 ng/mL) and vitamin B 12 ≥ 148 pmol/L (≥ 200 pg/mL), no overt hemolysis, and no overt gastrointestinal bleeding or bleeding due to recent surgery) Adequate renal function (creatinine ≤ 177gmol/L (≤ 2.0 mg/dL) and adequate hepatic function (bilirubin ≤ 1.5 times central laboratory's upper limit of normal range) Available for 4 weeks post administration of the last dose of study drug Legal age for informed consent, and written informed consent must be obtained Exclusion Criteria: History of any primary hematological disorder which could cause anemia (e.g., sickle cell anemia) Received prior whole pelvis radiation therapy Uncontrolled angina, congestive heart failure (New York Heart Association > class II or known ejection fraction < 40%)], or uncontrolled cardiac arrhythmia. History of primary or metastatic malignancy involving the central nervous system (CNS). Subjects with a previous history of primary or metastatic malignancy involving the CNS will be eligible for the study providing they have had no clinical signs of nor treatment for CNS disease and no history of seizures within previous 2 years Uncontrolled hypertension (i.e., diastolic blood pressure > 100 mm Hg) History of seizures. Subjects with a previous history of seizures will be eligible for the study providing they have had no evidence of seizure activity and have been free of anti-seizure medication for the previous 5 years Evidence of clinically significant systemic active infection or chronic inflammatory disease (e.g., rheumatoid arthritis) Iron deficiency (transferrin saturation < 15% and ferritin < 10 μg/L (< 10 ng/mL)) Received > 2 RBC transfusions within 4 weeks before randomization or any RBC transfusion within 2 weeks before randomization Received erythropoietin therapy within 8 weeks before randomization Known positive test for human immunodeficiency virus (HIV) infection Receiving, or not yet 30 days past the end of receiving, another investigational agent or device not approved in any indication. Pregnant or breast feeding females. Not using adequate contraceptive precautions Prior treatment with NESP Previously randomized in this study Known hypersensitivity to mammalian-derived product Concerns for subject's compliance with the protocol procedure, including completion of the quality of life surveys (QOLS)

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Percentage of Participants with a Red Blood Cell Transfusion During Weeks 5 to 12 |  | Weeks 5 to 12 | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Time to First Red Blood Cell Transfusion During Weeks 5 to 12 | The number of days from the first day of study week 5 (day 29) to the first administration of a RBC transfusion during the Treatment Phase that occurs on or after day 29. | Week 5 to week 12 | 
| Percentage of Participants with a Hemoglobin Response by Week 12 | Hemoglobin Response was defined as an increase in hemoglobin of ≥ 2.0 g/dL over baseline hemoglobin in the absence of any RBC transfusions during the preceding 28 days. | 12 weeks | 
| Time to Hemoglobin Response | The number of days from the first administration of study drug to the first occurrence of a hemoglobin response. | 12 weeks | 
| Percentage of Participants who Achieved a Sustained Hemoglobin Response by Week 12 | Sustained hemoglobin response was defined as in increase in hemoglobin of ≥ 2.0 g/dL over baseline hemoglobin sustained for at least 28 days or until the end of the Treatment Phase. This increase must have occurred in the absence of RBC transfusions during the period of sustained response and the preceding 28 days. | 12 weeks | 
| Time to Sustained Hemoglobin Response | The number of days from the first administration of study drug to the first occurrence of a sustained hemoglobin response. | 12 weeks |
