What is being measured
The primary outcome is the main question the study is designed to answer.
Total Dialysate Clearance for Automated Peritoneal Dialysis (CLDAPD) of Oseltamivir and Oseltamivir Carboxylate for 75 mg Dose
CLDAPD is the total dialysate clearance for automated peritoneal dialysis, attributable to both continuous cycler-assisted peritoneal dialysis (CCPD) and continuous ambulatory peritoneal dialysis (CAPD), which was calculated with the recovery method over the dense blood sampling collection interval from 0 to 48 hours post-dose.
CLDAPD = the amount excreted into dialysate from 0 to 48 hours (Aed[0-48])/ plasma area under the concentration-time curve from time zero through 48 hours (AUC[0-48])
CLDCCPD = mean of CLDCCPD from the 2 CCPD sessions, calculated as CLDCCPD = (Aed[0-8]/AUC[0-8] + Aed[24-32]/AUC[24-32]) / 2
CLDCAPD = mean of CLDCAPD from the 3 CAPD sessions, calculated as CLDCAPD = (Aed[8-16]/AUC[8-16] + Aed[16-24]/AUC[16-24] + Aed[32-48]/AUC[32-48]) / 3
Measured: CCPD: pre-dose (0)-2.67, 2.67-5.33, 5.33-8; CAPD: 8-16, 16-24; CCPD: 24-26.67, 26.67-29.33, 29.33-32; CAPD: 32-40, 40-48 hrs post-dose for urine; CCPD and CAPD:0.5, 1.33, 2, 2.5, 3, 4, 5, 6.67, 8, 10, 12, 14, 16, 20, 24, 28, 32, 48 hrs post-dose for blood

Secondary outcomes (4)
Number of Participants With Any Adverse Event (AEs) and Any Serious Adverse Events (SAEs)
An AE is defined as any untoward medical occurrence in a participant or clinical investigation participant administered a pharmaceutical product and which did not necessarily have to have a causal relationship with the intervention. An SAE is any untoward medical occurrence that, at any dose, results in death, is life threatening, requires hospitalization or prolongation of existing hospitalization, results in disability/incapacity, or results in a congenital anomaly/birth defect.
Measured: Approximately 7 weeks
Number of Participants With Marked Abnormality in Laboratory Measurements
Laboratory analysis included: hematology (hemoglobin, hematocrit, reticulocyte, red blood cell, platelet and white blood cell count, mean corpuscular volume, mean corpuscular hemoglobin), prothrombin and activated partial thromboplastin time, biochemistry (sodium, potassium, bicarbonate, phosphate, chloride, calcium, urea, serum creatinine, bilirubin, cholesterol, alkaline phosphatase, aspartate aminotransferase, alanine aminotransferase [ALT], gamma-glutamyl transferase, protein, albumin, amylase, creatinine, lipase), random glucose, and urinalysis.
Laboratory test result values falling outside of the marked abnormality range that also represent a defined change from baseline were considered as marked laboratory abnormalities. A marked reference range for sodium is 130-150 millimole (mmol)/L, chloride is 95-115 mmol/L, phosphate is 0.75-1.60 mmol/L, calcium is 2-2.90 mmol/L, glucose is 2.8-11.10 mmol/L, bicarbonate is 18-28 mmol/L, and ALT is 0-110 Unit/L.
Measured: Approximately 7 weeks
Number of Participants With Change From Baseline in Marked Abnormality in Electrocardiogram (ECG) Parameters at Follow-up Visit
ECG parameter included QT interval, QTcB interval and QTcF interval (all intervals are measured in millisecond [msec]). Marked abnormality in ECG is predefined for QT, QTcB, and QTcF interval as <=30, >30-60, and >60 msec increase from baseline.
Measured: From Baseline (Day -1) to Follow-up visit (Days 15 to 22)
Number of Participants With Abnormal Shifts in Vital Signs
Vital signs included pulse rate, systolic blood pressure (SBP), diastolic blood pressure (DBP), and body temperature.
Vital sign with abnormal shifts from normal at baseline to high or low at post-baseline time points were recorded. Blood pressure was recorded in millimeter of mercury (mmHg), and temperature in degrees Celsius. Low blood pressure defined as <=70 mmHg (SBP) and <=40 mmHg (DBP); high blood pressure defined as >=140 mmHg (SBP) and >=90 mmHg (DBP); low temperature defined as <=36.5 degrees Celsius and high temperature defined as >=37.5 degrees Celsius.
Measured: Days 1 (post-dose), 2, 3, 4, 5, 6, 7, 8; and Follow-up visit (Days 15 to 22)

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Tamiflu (oseltamivir) in people with Healthy Volunteer, run by Hoffmann-La Roche at 2 sites in New Zealand.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 8 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 7 Jul 2016. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites in New Zealand. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 7 Jul 2016). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Total Dialysate Clearance for Automated Peritoneal Dialysis (CLDAPD) of Oseltamivir and Oseltamivir Carboxylate for 75 mg Dose (time frame: CCPD: pre-dose (0)-2.67, 2.67-5.33, 5.33-8; CAPD: 8-16, 16-24; CCPD: 24-26.67, 26.67-29.33, 29.33-32; CAPD: 32-40, 40-48 hrs post-dose for urine; CCPD and CAPD:0.5, 1.33, 2, 2.5, 3, 4, 5, 6.67, 8, 10, 12, 14, 16, 20, 24, 28, 32, 48 hrs post-dose for blood). The study lists 7 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT01556633, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 7 Jul 2016.
