Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.
A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.
Read whether the line is about a condition or about medicines, and which medicines and doses it means.
The human immunodeficiency virus, which weakens the immune system.
Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.
A blood test of average blood sugar over the past two to three months, given as a percentage or in mmol/mol. 6.5% (48 mmol/mol) or more is the usual threshold for diabetes, normally confirmed by a second test.
GFR (glomerular filtration rate) is how much blood the kidneys filter each minute. It is usually estimated from a blood test — eGFR, by formulas such as CKD-EPI or MDRD — and some studies ask for it to be measured directly instead. Usually given in mL/min/1.73 m².
Check the method, the units and the minimum the study states. A value of 90 or above is in the normal-or-high range, but kidney damage can show in other tests too.
A drug or device being studied in a clinical trial.
It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

To evaluate the infection control effect of bisphosphonate combined with vancomycin in treatment of refractory osteomyelitis.
Drug: Bisphosphonates Combined with Vancomycin
Effect of vancomycin on infection control of refractory osteomyelitis.
Drug: Vancomycin
Drug pages: Diphosphonates · Vancomycin
After undergoing debridement surgery for osteomyelitis. 1. Bisphosphonates: fasting oral alendronate 70mg/w for 24 weeks. 2. Vancomycin: intravenous infusion of 2 g/d, given twice with an interval of 12 hours, 1 g each time, treatment for 1 weeks, sequential oral linezolid for total 6 weeks, during which strict attention was paid to drug side effects.
After undergoing debridement surgery for osteomyelitis. 1. Placebo: fasting oral placebo 1 piece/w for 24 weeks. 2. Vancomycin: intravenous infusion of 2 g/d, given twice with an interval of 12 hours, 1 g each time, treatment for 1 weeks, sequential oral linezolid for total 6 weeks, during which strict attention was paid to drug side effects.
Infection control rate at 6 months
The primary outcome of this trial is the status of infection control within 6 months after treatment. Infection control is defined by meeting the following three criteria: (1) The patient's body temperature returns to normal, and the local wound heals well (no exudation or purulence, no redness, swelling, or pain). (2) Blood routine tests (white blood cell count, neutrophil ratio) and inflammatory markers (C-reactive protein (CRP), erythrocyte sedimentation rate (ESR)) show a progressive decrease until they return to normal levels. (3) X-ray imaging indicates the formation of new bone callus.
Time frame: 6 months
Infection control rate within 1 year
No clinical, biological, or radiological signs of infection (pain, fever); Or the same bacteria come back.
Time frame: 1 year
