NEUROIMPA - Intraarticular Application of Opioids in Chronic Arthritis of the Knee Joint
Study Details
Study Description
Brief Summary
To investigate pain and inflammatory parameters (cytokines, immune cells) in knee joint tissue of chronic arthritis patients following intraarticular (i.a.) injections of morphine, a standard steroid or placebo.
The primary hypothesis is that i.a. morphine results in significantly lower pain scores and supplemental analgesic consumption than placebo during the first week after injection, an efficacy comparable to standard i.a. steroid (triamcinolone) medication.

Phase 2/Phase 3 |
Detailed Description
3 arm, double blind, placebo controlled, prospective, mo-nocenter study, which will be conducted in the Department of Rheumatology, Charité University Medicine Berlin, Cam-pus Benjamin Franklin in collaboration with several rheu-matology and orthopedic practices in the Berlin area. Ultra-sound guided synovial needle biopsy and interventions will only be performed at CBF.
Eligible patients will be treated with either morphine 3 mg i.a., NaCl 0.9% i.a. or triamcinolone 40 mg i.a. at Baseline. The entire study period will be 2 weeks per patient.
Assessment of the primary outcome parameter will be at week 1. The patients will be monitored closely throughout the entire study period with a total of 4 visits (screening, baseline, week 1, week 2).
Safety data will be collected in the adverse events form, vital parameters, physical examination and laboratory tests dur-ing the whole study.

Eligibility Criteria
Criteria
Inclusion Criteria:
-

-
baseline pain score (on a 100 mm Visual Analogue Scale, VAS) >40 mm;
-
male and female patients, age ≥18 - 80 years,
-
body weight 50 - 90 kg.
-
Able and willing to give a written informed consent and comply with the requirements of the study protocol. Only patients who give written informed consent will be in-cluded in the trial.
-
If female: either not of child-bearing potential (meno-pausal since 1 year or surgically sterile) or is willing and able to practice a reliable method of contraception throughout the study with a pearl index <1. Reliable methods of contraception are: condoms plus other methods: implants, injecatbles, combined oral contracep-tives, intrauterine devices, initiated at least 90 days prior to screening. Further reliable methods are a vasecto-mised partner (at least 1 year prior to enrolment), sexual-ly abstinent, surgically sterilized (including hysterecto-my), postmenopausal defined as at least 1 year of spon-taneous amenorrhea (in questionable cases a blood sample with simultaneous levels of follicle stimulating hormone (FSH) above 40 U/l and estradiol below 30 nl/l is confirmatory).
-
If male: either not of child-bearing potential (surgically sterilized, e.g. vasectomy) or is willing and able to prac-tice a reliable method of contraception with a pearl index <1 (see inclusion criterium 6) throughout the study.
