Transient adverse effects seen with the administration of CUROSURF (poractant alfa) include bradycardia, hypotension, endotracheal tube blockage, and oxygen desaturation. Pulmonary Hemmorhage is a known complication of premature birth and very low birth-weight and has been reported both in clinical trials with Curosurf (poractant alfa) and in post-marketing adverse event reports in infants who had received Curosurf (poractant alfa) . The rates of common complications of prematurity observed in Study 1 are shown below in Table 3.

* Control patients were disconnected from the ventilator and manually ventilated for 2 minutes. No surfactant was instilled.

Immunological studies have not demonstrated differences in levels of surfactant-anti-surfactant immune complexes and anti-CUROSURF (poractant alfa) antibodies between patients treated with CUROSURF (poractant alfa) and patients who received control treatment.

Follow -Up Evaluations

Seventy-six infants (45 treated with CUROSURF (poractant alfa) ) were evaluated at 1 year of age and 73 infants (44 treated with CUROSURF (poractant alfa) ) at 2 years of age. Data from follow-up evaluations for weight and length, persistent respiratory symptoms, incidence of cerebral palsy, visual impairment, or auditory impairment was similar between treatment groups. In 16 patients (10 treated with CUROSURF (poractant alfa) and 6 controls) evaluated at 5.5 years of age, the developmental quotient, derived using the Griffths Mental Developmental Scales, was similar between groups.
