Study BCX1812-109 was a Phase 1 open-label, randomized, 3-period, 3-sequence
crossover drug interaction study of peramivir and oseltamivir in healthy adult volunteers
(N=21). Following IV administration of 600 mg peramivir in combination with oral
oseltamivir (75 mg), the PK parameters for peramivir and oseltamivir carboxylate, the
active moiety, showed no evidence of a drug interaction. The study medications
(oseltamivir and peramivir taken individually or together) were generally well tolerated.
The most common TEAE reported was headache, reported by 2 subjects (10%) in each
cohort. All TEAEs were mild. The most common TEAEs considered by the investigator
to be possibly, probably, or likely related to the study drugs were headache, dizziness,
and influenza-like illness. No deaths or other SAEs were reported and no subjects
withdrew from the study due to TEAEs. No substantial differences in clinical chemistry,
hematology, or urinalyses values were noted between study sequences or from
Baseline to Day 2 visits. The highest graded post baseline laboratory shifts were all
Grade 1.
