Study Endpoints

Primary Endpoints

Area Under the Plasma Concentration-time Curve From Time Zero (Pre-dose) to Last Time of Quantifiable Concentration Within a Participant Across All Treatments (AUC[0-t]) for Ciprofloxacin
Pre-dose and 0.50, 0.75, 1.00, 1.25, 1.50, 1.75, 2.00, 2.50, 3.00, 3.50, 4.50, 6.00, 8.00, 12.00, 18.00 hours post-dose on Day 1; 24.00 hours post-dose on Day 2 in each treatment period

Blood samples were collected from participants at indicated time points in each of the treatment period 1 and 2, after administration of study treatment to investigate the pharmacokinetics of ciprofloxacin under fasted state. Pharmacokinetic analysis of ciprofloxacin was conducted using non-compartmental methods. Pharmacokinetic Population comprised of participants who completed the study and for whom primary pharmacokinetic parameters could be calculated for all treatment periods were included in the statistical pharmacokinetic analysis of the study.

Frequently asked questions about GR37547

What is GR37547 used for?

GR37547 is an investigational small molecule being developed for bacterial infections. It is currently in Phase 1 clinical development. A completed bioequivalence study evaluated a 500 milligram tablet of GR37547 against a reference ciprofloxacin 500 milligram tablet in healthy adult subjects.

Who makes GR37547?

GR37547 is being developed by GSK plc, a biopharmaceutical company listed on the stock exchange under the ticker GSK. The drug is currently in Phase 1 clinical development for bacterial infections.

What phase is GR37547 in?

GR37547 is in Phase 1 clinical development. It is an investigational drug, not yet approved by regulatory authorities. One Phase 1 trial has been completed, involving 26 healthy adult subjects.

What clinical trials is GR37547 in?

GR37547 has one completed clinical trial, registered under NCT03150082. This was a Phase 1 bioequivalence study comparing a 500 milligram tablet of GR37547 to a reference ciprofloxacin 500 milligram tablet in healthy adult subjects. The trial was conducted in South Africa.

Is GR37547 the same as ciprofloxacin?

GR37547 is not the same as ciprofloxacin. A Phase 1 bioequivalence study compared a 500 milligram tablet of GR37547 to a reference ciprofloxacin 500 milligram tablet in healthy adult subjects. The study was designed to assess whether the two products are bioequivalent.
