Epoetin Alpha Study 1
Epoetin Alpha Tthe number of separate doses (per kg) to be given over 4 weeks by day of age will not exceed 10. These will be administered as follows: day of life (DOL) 2 (1200 U), DOL 4 (600 U), DOL 5 (600 U), DOL 6 (600U), DOL 7 (600 U), DOL 9 (600 U), DOL 14 (600 U), DOL 15 (600 U), DOL 16 (1200 U), and DOL 28 (600 U). The greatest dose in any 1 wk period is 3600 U. Infant study 1 Drug Intervention: all infants will be treated with Epoetin Alpha during the first four weeks of life to provide data for determining: 1) the PK/PD model determined optimized Epoetin Alpha dosing schedule; and 2) clinical and laboratory covariates predictive of which infants are good and poor Epoetin Alpha responder. Epoetin Alpha: Infant study 1: VLBW infant study subjects (weighing 1.0 to 1.5 kg at birth) who are otherwise receiving standard clinical care will be treated with Epoetin Alpha according to a dosing algorithm. Infant study 2: Dosing algorithm will be determined by results of Infant Study 1.

Standard Deviation 1.0

PRIMARY outcome

Timeframe: Plasma concentrations collected at multiple time points within 48 hours after each dose during the first 28 days of life.

First-order absorption rate constant (Ka) estimated using a population pharmacokinetic model. The estimate was derived from plasma erythropoietin concentration data collected at multiple time points following dosing throughout the 28-day study period.

Interval 0.06 to 0.088

PRIMARY outcome

Timeframe: Plasma concentrations measured at multiple time points within 48 hours after each dose during the first 28 days of life.

Bioavailability estimated using a population pharmacokinetic target-mediated drug disposition (TMDD) model. Bioavailability represents the fraction of the administered dose reaching the systemic circulation and is reported as a unitless proportion ranging from 0 to 1. The estimate was derived from plasma erythropoietin concentration data collected at multiple time points following dosing throughout the 28-day study period.
