Number of Participants With Adverse Events by Highest World Health Organization (WHO) Toxicity Grade
The WHO Toxicity Grading Scale was used for assessing adverse event severity. Any adverse event not specifically listed in the WHO Toxicity Grading Scale was assessed according to the following levels of severity: Grade 1 is mild; Grade 2 is moderate; Grade 3 is severe; and Grade 4 is life-threatening. Investigator text for adverse events were encoded using the Medical Dictionary for Regulatory Activities (MedDRA) version 21.1. After informed consent had been obtained but prior to initiation of study drug, only serious adverse events (SAEs) caused by a protocol-mandated intervention were to have been reported. After initiation of study drug, all adverse events, regardless of relationship to study drug, were to have been reported until the participant completed his last study visit. After this period, any SAEs believed to be related to prior study drug treatment were to be reported.
Measured: From screening to study completion (20 weeks)
Number of Participants Testing Negative or Positive for the Presence of Anti-Drug Antibodies (ADA) Against Emicizumab by Timepoint and for the Overall Study
Participants were considered to be 'ADA Negative (Treatment Unaffected)' if baseline and all post-baseline samples were negative, or if they were ADA positive at baseline but did not have any post-baseline samples with a titer that was at least 4-fold greater than the titer of the baseline sample. 'Total ADA Positive' is the sum of all participants who tested positive for ADA in the 2 following categories: 'ADA Positive (Treatment Induced)', those who were ADA negative at baseline and tested positive for ADA following study drug administration; and 'ADA Positive (Treatment Boosted)', those who were pre-dose ADA positive and had post-baseline samples with a titer that was at least 4-fold greater compared to the baseline measurement.
Measured: Predose at Baseline (Day 1) and postdose on Days 57 and 113
Number of Participants With Laboratory Test Abnormalities
The number of participants with a laboratory abnormality during treatment (numerator) is reported among the 'number analyzed' in the table below (denominator), which represents the number of participants without that abnormality at baseline (last observation prior to initiation of study drug). Note that samples from all participants were analyzed for each laboratory parameter. Values falling above or below the Roche predefined standard reference range were laboratory abnormalities labelled accordingly as 'high' or 'low'. Not every laboratory abnormality qualified as an adverse event; only if it was accompanied by clinical symptoms, resulted in a change in study treatment or in a medical intervention, or was clinically significant in the investigator's judgment. SGOT/AST = serum glutamic-oxaloacetic transaminase/aspartate transaminase; SGPT/ALT = serum glutamic-pyruvic transaminase/alanine transaminase

Number of Participants With Concomitant Medications
The original terms recorded by the investigator for concomitant medications were standardized by the sponsor by assigning preferred terms. The duration of treatment with the concomitant medications ranged from 1 day to 5 days. Except for 1 participant who was treated during the in-clinic period (Days -1 to 4), all other concomitant medications were recorded during the ambulatory period (Days 6 to 113).
Measured: From screening to study completion (20 weeks)

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Emicizumab in people with Healthy Volunteers and Hemophilia A, run by Hoffmann-La Roche at 1 site in China.
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 4 inclusion and 12 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 30 Sep 2019. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. 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 30 Sep 2019). 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?
Maximum Observed Plasma Concentration (Cmax) of Emicizumab (time frame: Predose on Day 1 and postdose on Days 2, 4, 6, 8, 11, 15, 22, 29, 36, 43, 50, 57, 71, 85, and 113). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 30 Sep 2019.
