Main objective
Scope: Therapy
To investigate whether early transition to oral antibiotic (AB) treatment after one week of intravenous (IV) treatment is non-inferior to the current national guideline of continued IV AB treatment for two to four weeks followed by oral AB treatment for pyogenic vertebral osteomyelitis (PVO).
Secondary objectives 5
- 1. To compare the proportion of patients experiencing treatment-related adverse events between treatment arms at six months after oral AB treatment cessation.
- 2. To compare the average total number of hospital admission days between treatment arms at six months after oral AB treatment cessation.
- 3. To compare self-assessed health related quality of life (EQ5D) during and until 12 months following cessation of antibiotic therapy.
- 4. To assess the economic impact of early shift from IV to oral AB at 6 months following cessation of antibiotic therapy.
- 5. Assessment of sequencing of microbial cell-free DNA as a diagnostic tool in blood from patients with PVO.

Eligibility criteria
Principal inclusion / exclusion criteria as submitted by sponsor
Inclusion criteria 5
- Age ≥18 years
- Diagnosed with PVO by a physician based on clinical symptoms and findings consistent with PVO in combination with diagnostic imaging (MRI, PET/CT or PET/MRI) or perioperatively identified
- The physician responsible for the patient decides to treat the patient for PVO
- At time of randomization CRP has decreased to < 75% of peak value or to < 20 mg/l
- At the time of randomization patient has received maximum 7 days of appropriate IV AB for PVO
Exclusion criteria 14
- Previous episodes of PVO within the past 24 months
- Verified or expected reduced compliance (for example iv drug use)
- Pregnancy
- Diagnosed or suspected concomitant or unrelated infections necessitating IV AB therapy beyond 7 days of duration at the time of randomization
- Breastfeeding
- Patients not capable of providing informed consent at time of screening for inclusion
- Spinal implants inserted prior to current episode of PVO with P. aeroginosa identified as etiology for current PVO
- Hypersensitivity to an AB intended for use in the patient and no alternative drugs available.
- Oral ABs not possible due to suspicion of reduced absorption
- Oral Abs not possible due to verified or expected bacterial susceptibility or due to expected toxicity of available regimen
- Identification of fungus, mold, TB, Brucella, Actinomyces and/or Nocardia as etiology
- Severe immunocompromise defined as transplant recipients, patients having hematological malignancies currently undergoing or having undergone active medical treatment within the last six months, patients having solid organ cancers currently undergoing immunosuppressive treatment, or at current risk of febrile neutropenia and patients having received an IL6 inhibitor within the last 3 months
- Women of childbearing potential, who at the time of inclusion are not using and/or who will not use an effective anticonception method during the treatment period.
- A positive blood-culture taken 48-72 hours after initiation of appropriate therapy for PVO in patients having S. aureus bacteremia
Endpoints
Primary and secondary outcome measures (English text)
Primary endpoints 1
- A composite of the following occurring from randomization to six months after completion of oral AB •All-cause mortality •Unplanned surgical intervention in relation to the spine and paravertebral tissue including the illopsoas muscle for treatment of PVO. •Relapse bacteremia with primary pathogen •Relapse of bacteria with the initial pathogen cultured from relevant material from infected areas in relation to the spine or iliopsoas • Renewed course of IV ABs given for >7 days for PVO
Secondary endpoints 13
- Occurrence of each component of the composite primary endpoint from randomization to six months after completion of oral AB treatment.
- Median duration of hospital admission(s) from the time of randomization to six months after completion of oral AB treatment (Admission defined as overnight stay at the department)
- Number of readmissions from the time of randomization to six months after completion of oral AB treatment
- Proportion of patients receiving additional oral AB therapy beyond the duration defined in the protocol
- Proportion of patients having early termination of allocated treatment strategy due to adverse events, patient preference, or any other reason
- Proportion of patients experiencing complications associated with IV treatment (e.g., catheter infections, phlebitis, bleeding, venous thrombosis, need for replacement of catheter) from the time of initiation of IV treatment for PVO to six months after completion of oral AB treatment
- Proportion of patients experiencing severe adverse events from ABs from randomization to six months after completion of oral AB treatment
- Proportion of patients diagnosed with Clostridioides difficile associated diarrhea from randomization to six months after completion of oral AB treatment
- Quality of life scores (EQ-5D) at the following timepoints: Randomization, 1 week after the end of AB therapy, 6 months after the end of oral AB therapy, and 12 months after the end of oral AB therapy
- Resource allocation/cost assessment determined by a combination of EQ5D, DALYs, Days of hospital admission and antibiotic prescribing costs
- CRP and WBC at randomization as well as CRP and WBC weekly during treatment and at week 4, 12 and 24 after completion of oral AB treatment.
- Presence of microbial cell-free DNA in blood samples at the time of randomization and 6 months after the end of oral AB therapy
- Proportion of patients given more than 5 days IV antibiotic therapy during the oral antibiotic-treatment phase for an unrelated intercurrent illness, or if the patient experiences vomiting or is unable to swallow, or concerns arise about absorption of oral medication.
