January 21, 2016 updated by: Durata Therapeutics Inc., an affiliate of Allergan plc
A Phase 3, Double-blinded, Randomized, Comparator Trial of the Safety and Efficacy of a Single Dose of Dalbavancin to Twice Daily Linezolid for the Treatment of Community Acquired Bacterial Pneumonia
This study will be a double-blind, randomized, multicenter trial to assess the safety and efficacy of a single 1500 mg IV dose of dalbavancin plus a single 500 mg IV dose of azithromycin in comparison to an approved antibiotic regimen of linezolid 600 mg every 12 hours for 10-14 days plus a single 500 mg IV dose of azithromycin for the treatment of Community Acquired Bacterial Pneumonia.

Detailed Description
This study will be a double-blind, randomized, multicenter trial to assess the safety and efficacy of a single 1500 mg IV dose of dalbavancin plus a single 500 mg IV dose of azithromycin in comparison to an approved antibiotic regimen of linezolid 600 mg every 12 hours for 10-14 days plus a single 500 mg IV dose of azithromycin for the treatment of CABP.
Adult patients who meet all inclusion and none of the exclusion criteria will be randomized to one of the two treatment arms.
Dosing will commence on Day 1, and all patients will receive a minimum of 10 days of therapy.
Patients will be assessed on Day 1, Day 4-5, Day 7, Day 14 (End of Therapy, EOT), and Day 28 (Follow up).

Experimental: Dalbavancin
Dalbavancin randomized subjects will receive one dose of dalbavancin 1500 mg IV over 30 minutes on Day 1 plus azithromycin 500 mg IV on Day 1. Dalbavancin dose will be adjusted for subjects with significant renal insufficiency who are not receiving regular hemodialysis.
All patients in the dalbavancin group will receive placebo linezolid infusions or tablets to maintain the blinding.
Dalbavancin dose will be adjusted for subjects with significant renal insufficiency who are not receiving regular hemodialysis
|
dalbavancin 1500 mg IV over 30 minutes on Day 1

|
Active Comparator: Linezolid
Linezolid randomized subjects will receive linezolid 600 mg every 12 hours for a minimum of 10 days, and a maximum of 14 days.
All patients will receive at least one IV dose of linezolid initially plus azithromycin 500 mg IV only on Day 1. Subjects then may then be switched to oral linezolid at the discretion of the investigator, if clinical improvement in the signs and symptoms of pneumonia is observed, to complete the 10-14 day course of therapy,.
No dose adjustment is required for renal insufficiency.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Treatment Response of CABP Symptoms
Time Frame: Change from Baseline to 72-120 hours after randomization
|
Compare the efficacy of a single 1500 mg dose of intravenous dalbavancin plus azithromycin to the comparator regimen (linezolid plus azithromycin).
Response will be based on resolution of symptoms; including chest pain, shortness of breath (difficulty breathing), frequency/severity of cough and amount of sputum production.
Each of these symptoms will be assessed on a 4 point scale (absent, mild, moderate or severe).
A patient will be defined as a clinical responder if there is at least a 1 point improvement in 2 or more of these symptoms at 72-120 hours after randomization compared to baseline.

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Efficacy of dalbavancin to the comparator regimen
Time Frame: Change from baseline to 72-120 hours after randomization, Day 14 and Day 28
|
Test the efficacy of dalbavancin to the comparator regimen using alternative outcome measures including:1) improvement at Day 4-5 in at least two of the following symptoms with no worsening in any of these symptoms of CABP compared to baseline: chest pain, frequency or severity of cough, amount of productive sputum, and difficulty breathing and improvement in vital signs (i.e.
temperature, heart rate, respiratory rate or blood pressure); 2) clinical outcome (using primary response criteria) at Day 14; 3) Investigator Assessment of Outcome at Day 14 and Day 28, with success defined as complete resolution of symptoms and signs attributable to CABP and did not receive non-trial antibacterial drugs for treatment of CABP.4) all-cause mortality at Day 28
|
Change from baseline to 72-120 hours after randomization, Day 14 and Day 28
|
Safety Analysis
Time Frame: Safety will be assessed at all time-points through Day 28
|
To test the safety profile of dalbavancin 1500 mg versus comparator.
Safety will be assessed by means of physical examination and vital signs, collection of adverse, events and clinical laboratory tests through out the study.
|
Safety will be assessed at all time-points through Day 28
