What is being measured
The primary outcome is the main question the study is designed to answer.
Early Clinical Response Rate (ECRR): Percentage of Responders to Treatment at 48 to 72 Hours From Randomization as Assessed by the Investigator
ECRR was defined as the percentage of responders to treatment at 48 to 72 hours from randomization. Responders were the participants who showed greater than or equal to (≥) 20% reduction in area of the primary lesion involving erythema, edema, or induration of the primary ABSSSI lesion (as assessed by the ruler method) at 48 to 72 hours compared to baseline.
Measured: At 48 to 72 hours from randomization (Day 4)
Secondary outcomes (4)
Clinical Success Rate: Percentage of Participants Assessed by the Investigator as Responders at 48 to 72 Hours From Randomization, at End of Treatment (EOT) and Short-term Follow-up (STFU)
The Investigator Assessment of Clinical Outcome (IACO) of treatment was assessed for each participant as success or failure at 48 to 72 hours after randomization at EOT and STFU visits. Clinical success was resolution or near resolution of most disease-specific signs and symptoms and no new signs, symptoms, or complications attributable to ABSSSI such that no further antibiotic therapy is required for treatment of original site of infection. Clinical failure was requirement for additional antibiotic therapy for treatment of the original site of infection or incision and drainage of ABSSSI site that was not both anticipated and completed within a 48- to 72-hour window following randomization, or unplanned major surgical intervention required due to failure of study medication or development of osteomyelitis after baseline. Participants who met both success criteria and none of failure criteria were considered as a clinical success for IACO.
Measured: 48 to 72 hours after randomization (Day 4), EOT (Day 12) and STFU (Day 19)
Clinical Success Rate: Percentage of Participants Assessed by the Sponsor as Responders After 7 to 10 Days of Treatment at EOT and STFU
The Sponsor's Assessment of Clinical Outcome was obtained at EOT and STFU visits based on IACO and additional criteria. Sponsor assessed participants as clinical failure if they required non-study or rescue antibiotics due to lack of efficacy after at least 48 hours from randomization or experienced drug-related serious adverse events (SAEs) or discontinuation of study medication for drug-related AEs or required antibiotic therapy for longer than 10 days or had the need for unplanned surgical intervention >48 hours after randomization. As per IACO, clinical success was resolution or near resolution of most disease-specific signs and symptoms and no new signs, symptoms or complications. Clinical failure was requirement for additional antibiotic therapy or incision and drainage of ABSSSI site or unplanned major surgical intervention or development of osteomyelitis.
Measured: EOT (Day 12) and STFU (Day 19)
Percentage of Participants With a Composite Assessment of Clinical Outcome (CACO) of Success
CACO of treatment was determined as a combined outcome of early response to treatment (at 48 to 72 hours from randomization) and IACO at the STFU visit. Participants had a CACO of success if they met both of the following criteria: An early response to treatment (at 48 to 72 hours from randomization) (ECR = responder) and a clinical outcome of success at the STFU visit (7 to 14 days after EOT) based on IACO (IACO = success).
Measured: 48 to 72 hours after randomization (Day 4) and STFU (Day 19)
Percentage of Participants Who Showed Microbiological Evidence of Cure 48 to 72 Hours From Randomization, EOT, and STFU
The microbiological outcome was assessed by the sponsor at 48 to 72 hours from randomization, EOT and STFU. It was based on blood and skin lesion identification results from baseline samples and skin lesion identification results from baseline samples and skin lesion identification results from follow-up samples as well as on, molecular typing results, and the IACO. Microbiological eradication rate was defined as proportion of participants with 'Documented Eradication' (absence of baseline pathogen(s) in follow-up cultures of the original site of infection.) or 'Presumed Eradication' (no material available for culture and an IACO of 'Success') in relation to the total number of participants in the respective treatment group.
Measured: 48 to 72 hours after randomization (Day 4), EOT (Day 12) and STFU (Day 19)

A Phase 2 study testing Debio 1450 IV, Debio 1450 Oral and Linezolid in people with Bacterial Infections, run by Debiopharm International SA at 22 sites in United States.
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 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 13 Nov 2019. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 22 sites in United States. 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. Some participants in this study may receive a placebo. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
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 13 Nov 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?
Early Clinical Response Rate (ECRR): Percentage of Responders to Treatment at 48 to 72 Hours From Randomization as Assessed by the Investigator (time frame: At 48 to 72 hours from randomization (Day 4)). 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 NCT02426918, 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 13 Nov 2019.
