Trial Summary

What is the purpose of this trial?

Standard of care for patients with opioid use disorder and complicated infections is discharge to subacute nursing facilities on IV antibiotics until completion of treatment course. We aim to determine the efficacy of an alternative strategy using intermittent outpatient oritavancin therapy dosed weekly combined with initiation and continuation of medication assisted treatment for opioid use disorder for completion of antimicrobial therapy in a 12 week prospective, open-label study. Patients hospitalized for a drug use related infection and thought to need prolonged parenteral antimicrobial therapy will be assessed by a substance use consultant and Infectious Diseases service. If they are not on Medication for Opioid Use Disorder (MOUD), they will be assessed for initiation of MOUD. A collaborative multidisciplinary discharge planning process will be initiated and will involve linkage to care. If they have an infection with a gram positive organism, and are thought to be clinically stable for hospital discharge, they will be assessed for appropriateness for oritavancin and first dose will be administered prior to discharge. They will have an intake into an opioid treatment program where they can access collocated services and will be discharged with linkage to care through a peer recovery coach. They will be assessed in this collocated clinic post discharge for optimization of MOUD and progress of infection and subsequent dose/s of oritavancin will be administered. Patients will be followed for 12 weeks for cure/completion of therapy and MOUD outcomes.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but it mentions that you cannot be on prohibited concomitant medications. It's best to discuss your current medications with the trial team to see if any adjustments are needed.

What data supports the effectiveness of the drug Oritavancin for infections and opioid use disorder?

Oritavancin is effective for treating skin infections, as it was shown to work as well as vancomycin, a common antibiotic, in clinical trials. However, there is no direct evidence from the provided research that supports its effectiveness for opioid use disorder. ^{1 2 3 4 5}

What makes the drug Oritavancin unique for treating infections and opioid use disorder?

Oritavancin is unique because it combines its antibacterial properties with potential benefits for opioid use disorder, leveraging its dual-acting mechanism on kappa and mu opioid receptors, which are involved in pain and addiction pathways. ^{6 7 8 9 10}

Eligibility Criteria

This trial is for adults over 18 with opioid use disorder who have infections from drug use, need long-term IV antibiotics, and are stable enough to leave the hospital. They must not be on opioid therapy but willing to start MOUD (like methadone/suboxone), follow up at a clinic, and if female, agree to effective birth control or be postmenopausal/sterilized.

Inclusion Criteria

I have an infection from drug use requiring long-term IV antibiotics.

I am 18 years old or older.

Findings from Research

Kimyrsa, a new formulation of oritavancin, offers a shorter infusion time and greater flexibility with solution compatibility while maintaining a similar pharmacokinetic and microbiologic profile to the original formulation.

Despite these advantages, Kimyrsa currently lacks significant real-world experience compared to other lipoglycopeptides, making its exact role in treatment uncertain but likely similar to that of the original formulation.

The review of 18 studies indicates that treating ADHD in patients with opioid use disorder (OUD) can lead to better retention in OUD treatment programs and improvements in ADHD severity.

While the specific medications for OUD treatment could not be prioritized, the findings suggest that addressing ADHD symptoms is important for reducing illicit substance abuse in these patients.

Oritavancin is a new lipoglycopeptide antibiotic that is as effective as vancomycin for treating acute bacterial skin infections, based on phase 3 trials involving adult patients, with results assessed 48-72 hours after treatment initiation.

It is well tolerated with mostly mild side effects, and its single-dose administration offers advantages like reduced hospital stays and no need for dosage adjustments in patients with liver or kidney issues.

An integrated drug repurposing strategy identified five candidate medications (tramadol, olanzapine, mirtazapine, bupropion, and atomoxetine) that significantly increase the odds of remission from opioid use disorder (OUD), based on analysis of electronic health records from over 72.9 million patients.

These candidate drugs target multiple genes and pathways associated with OUD, suggesting they may effectively address both OUD and related comorbid conditions.

In a study of 336 patients treated with elbasvir/grazoprevir (EBR/GZR), an impressive 318 (95%) achieved sustained virologic response at 12 weeks (SVR12), indicating high efficacy in real-world settings.

However, people who injected drugs (PWID) with recent drug use had significantly lower SVR rates (69%) compared to those without recent drug use (97%), highlighting the need for targeted interventions for this group.

The newly discovered compound, identified as 10, is a potent antagonist of the opioid receptor-like 1 (ORL1) with strong selectivity, meaning it effectively targets ORL1 without significantly affecting other opioid receptors.

Compound 10 has demonstrated in vivo efficacy after oral administration, and it is currently undergoing clinical trials, indicating its potential as a therapeutic option.

The compound 1d, a phenyl ring analogue of buprenorphine, shows high affinity for μ, κ, and δ opioid receptors while also having moderate affinity for nociceptin opioid peptide receptors, making it a promising candidate for preventing relapse in drug abuse.

In vivo studies confirmed that 1d does not exhibit opioid agonist activity, effectively acting as an antagonist to both morphine and ethylketocyclazocine, which supports its potential as a safe treatment option without the risk of opioid-like effects.

The study developed a predictive model for the efficacy of dual-acting kappa opioid receptor (KOR) agonist and mu opioid receptor (MOR) partial agonist ligands, showing that modifications to the chemical structure can influence receptor activity.

In vivo tests of two selected ligands confirmed their KOR activity and some MOR activity, indicating that in vitro efficacy measures can reliably predict how these compounds will perform in living organisms.
