- Primary Outcome Measures
Name Time Method Pharmacodynamics measured by the following variables: - Serum neopterin levels (values expressed in ng/mL). Time measurement: Before and 6, 12, 24, 48, 72, 96, 120, 168 and 192 hours after injection at each treatment period. - Serum?ß2-microglobulin (ß2M) (values expressed in µg/mL). Time measurement: Before and 6, 12, 24, 48, 72, 96, 120, 168 and 192 hours after injection at each treatment period. - 2',5' oligoadenylate synthetase (2',5' OAS) mRNA expression in peripheral blood (RNA concentration). Time measurement: Before and 6, 12, 24, 48, 72, 96, 120, 168 and 192 hours after injection at each treatment period.
- Secondary Outcome Measures
Name Time Method Pharmacokinetics and clinical evaluation measures through the following variables: - Serum levels of interferon alpha and interferon gamma (values ??expressed pg/mL). Measuring time: at baseline and at 2, 3, 4, 6, 7, 8, 10, 12, 14, 16, 24, 36 and 48 hours after administration. - Vital signs (body temperature in degrees Celsius, heart rate in beats per minute, blood pressure in mm Hg and respiratory rate in breaths per minute). Measuring time: at baseline and at 2, 3, 4, 6, 7, 8, 10, 12, 14, 16, 24, 36, 48, 72, 96, 120, 168 and 192 hours in each period. - Determination of hematology and clinical chemistry (numerical values ??as measurement units for each determination). Measuring time: at baseline and at 24, 48, 72, 96, 120, 168 and 192 hours after administration of interferons, in each period.
