Study Summary

This trial is testing a new drug to see if it can make it easier to treat infections in people with artificial joints. The goal is to show that the drug can help a lot of people with this infection.

Who is the study for?
This trial is for adults with knee or hip prosthetic joint infections who are scheduled for a two-stage exchange arthroplasty, have a BMI under 40, and can follow the study plan. They must not have other active infections, recent cancers, autoimmune diseases, uncontrolled diabetes, significant heart or liver issues, drug/alcohol abuse history or be immunocompromised.Check my eligibility
What is being tested?
TRL1068 is being tested to see if it can break down biofilms protecting pathogens in infected joints making them more vulnerable to antibiotics. This first study looks at its safety and how the body processes it. The aim is to help patients keep their original prosthetic joint or successfully replace it.See study design
What are the potential side effects?
While specific side effects of TRL1068 aren't listed here as this is an initial study assessing safety and PK; generally monoclonal antibodies may cause allergic reactions, infusion-related symptoms like fever or chills, possible organ inflammation and increased infection risk.

Frequently Asked Questions

These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.

How many healthcare centers are hosting this clinical investigation?

"Currently, 4 sites are running this trial. Participants can choose from Tamarac, Baltimore and Santa Monica or any of the other available locations for easier access to medical care."

Answered by AI

Am I eligible to participate in this experimental research?

"For eligibility, individuals must be aged 18-85 and have an infection. With 28 places available, this medical trial is open to applicants that meet these criteria."

Answered by AI

Does TRL1068, a human monoclonal antibody, present any risk to those taking part in the trial?

"Given the limited clinical data surrounding TRL1068, a human monoclonal antibody, our team has assigned it a safety score of 1. This is in keeping with Phase 1 trial expectations as efficacy and safety are still being evaluated."

Answered by AI

What is the intended outcome of this experiment?

"This 16-week trial will primarily monitor the Incidence of Abnormal Vital Signs (Heart Rate). Secondary objectives involve measuring the pharmacodynamics (PD) of TRL1068, including its Inflammatory biomarkers ESR and CRP. Furthermore, ELISA tests shall be used to measure serum and synovial concentrations of TRL1068 on Day 8."

Answered by AI

Is it still possible to register for this research initiative?

"Per the details on clinicaltrials.gov, this experiment is actively recruiting individuals. It was first advertised on February 8th 2021 and recently updated July 5th 2022."

Answered by AI

What is the aggregate participant count for this experiment?

"That is correct. According to the data posted on clinicaltrials.gov, this research endeavour initially went live on February 8th 2021 and was last updated July 5th 2022. 28 individuals have been targeted for recruitment across 4 different sites."

Answered by AI

Does this research project accept participants younger than age 55?

"According to the criteria of this trial, potential participants must be aged 18 years or older and no more than 85."

Why did patients apply to this trial?

I am on suppression antibiotics my infection is from pseudomonas aeruginosa and they tell me that there is nothing else that can be done and the next step would be amputation.i had three revision surgeries and had extensive repair of the soft tissue by a plastic surgery and he told me I couldn’t have anymore surgery on it. Trying a new drug is about all I can do.
