The Safety and Pharmacokinetics of Carbavance™ (RPX2014/RPX7009) in Subjects With Renal Insufficiency

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT02020434
Recruitment Status : Completed
First Posted : December 25, 2013
Last Update Posted : March 5, 2018
Information provided by (Responsible Party):
Rempex Pharmaceuticals (a wholly owned subsidiary of The Medicines Company)

Brief Summary:
RPX7009(beta-lactamase inhibitor) is being studied in combination with carbapenem (RPX2014)to treat bacterial infections, including those due to multi-drug resistant bacteria.

Condition or disease Intervention/treatment Phase
Subjects With Varying Degrees of Renal Insufficiency and Subjects With Normal Renal Function Drug: RPX7009 and RPX2014 Phase 1

Detailed Description:

The worldwide spread of resistance to antibiotics among Gram-negative bacteria, particularly members of the ESKAPE group of pathogens, has resulted in a crisis in the treatment of hospital acquired infections. In particular, the recent dissemination of a serine carbapenemase (e.g., KPC) in Enterobacteriaceae in US hospitals now poses a considerable threat to the carbapenems and other members of the beta-lactam class of antimicrobial agents.

Rempex is developing a fixed combination antibiotic of a carbapenem (RPX2014) plus a new beta-lactamase inhibitor (RPX7009) which has activity against serine beta-lactamases, including KPC. This Phase 1 study will assess the safety, tolerability and pharmacokinetics of intravenous RPX2014 and RPX7009, administered in combination in subjects with varying degrees of renal insufficiency.

Official Title: A Phase 1, Open-label, Single-dose Study to Determine the Safety and Pharmacokinetics of Carbavance™ (RPX2014/RPX7009) in Subjects With Renal Insufficiency
Study Start Date : January 2014
Actual Primary Completion Date : September 2014
Actual Study Completion Date : October 2014

Arm Intervention/treatment
Experimental: Single dose of RPX7009 and RPX2014
Single dose of combination RPX7009 and RPX2014
Drug: RPX7009 and RPX2014
The study is designed to enroll approximately 32 subjects. There will be approximately 24 subjects with varying degrees of renal insufficiency and approximately 8 subjects with normal renal function.

Primary Outcome Measures :
  1. Safety from baseline through the end of the study [ Time Frame: 7days ]
    Number of patients with adverse events; assessed by patient reporting, collection of vital signs, ECGs and absolute values and changes over time of hematology, chemistry and urinalysis
