Determination of the effect of balugrastim on the duration and severity of severe neutropenia.

Balugrastim (Neugranin) in Breast Cancer Participants Receiving Doxorubicin/Docetaxel

A Randomized Study of Subcutaneously Administered Neugranin (Recombinant Human Albumin-Human Granulocyte Colony Stimulating Factor) or Pegfilgrastim in Subjects With Breast Cancer Receiving Myelosuppressive Chemotherapy (Doxorubicin/Docetaxel)

Severe neutropenia was defined as Grade 4 neutropenia (absolute neutrophil count \[ANC\] \<0.5 x 10\^9/liter \[L\]). The duration of severe neutropenia was calculated by cycle as the number of days from the first day in which the ANC fell below 0.5 x 10\^9/L after beginning a chemotherapy cycle until the participant had an ANC ≥0.5 x 10\^9/L within the cycle.

Febrile neutropenia was defined as an imputed or observed ANC \<0.5 x 10\^9/L and oral temperature ≥38.2 degrees celsius (°C) occurring on the same day. Number of participants with febrile neutropenia over all cycles (Cycles 1 to 4) has been reported.

Severe neutropenia was defined as Grade 4 neutropenia (ANC \<0.5 x 10\^9/L). The duration of severe neutropenia was calculated by cycle as the number of days from the first day in which the ANC fell below 0.5 x 10\^9/L after beginning a chemotherapy cycle until the participant had an ANC ≥0.5 x 10\^9/L within the cycle.

Time to ANC recovery was defined as the time from the nadir ANC to an ANC ≥1.5 x 10\^9/L and was calculated for participants with ANC \<1.5 x 10\^9/L after the beginning of a chemotherapy cycle. Time to ANC recovery was calculated by cycle as the number of days from the nadir (the lowest ANC during a chemotherapy cycle) until a participant reached an ANC \>1.5 x 10\^9/L.
