About this study

Official title: Neodolpasse® Infusion Solution Versus Diclofenac 75 mg Infusion in the Treatment of Postoperative Pain After Elective Knee Surgery - an Exploratory Placebo-controlled Clinical Study to Investigate the Analgesic Properties of the Combination of Diclofenac and Orphenadrine Versus Diclofenac Alone.

The clinical study is planned as a double-blind, randomised, placebo-controlled, parallel-group, single-centre exploratory clinical study with the aim to investigate the analgesic efficacy of the Neodolpasse® Infusion Solution in comparison to a 75 mg diclofenac only infusion. Included will be Patients receiving elective cruciate ligament surgery. The effectiveness will be measured by the use of additional analgesic medication via PCA during the first 24 hours postoperatively as well as by using a Visual Analogue Scale (VAS). Furthermore the local and systemic tolerability and safety of the clinical study medications (i.e. Neodolpasse® Infusion Solution and 75 mg diclofenac only infusion) will be assessed.

Read the detailed description

The clinical study is planned as a double-blind, randomised, treatment-controlled, parallel-group, single-centre exploratory clinical study with the aim to investigate the analgesic efficacy of the Neodolpasse® Infusion Solution in comparison to a 75 mg diclofenac only infusion.

Patients who meet the inclusion and exclusion criteria will be enrolled to the clinical study and receive an enrolment number. The enrolment number will be a 4-digit number where the leftmost position will be zero ("0"). Enrolled patients will receive enrolment numbers starting at 0001, 0002, and so forth.

Only patients who were successfully randomized after surgery will continue the study protocol. All other patients will be regarded as screening failures. Successfully randomized patients will receive two infusions over 60 - 90 minutes with a time interval of 8 hours each during the first 24 hours postoperatively. All patients will be provided with a PCA device and will be allowed on demand analgetics as postoperative rescue medication. Consequently the possibility of an inadequate postoperative pain treatment in the study patients is very low.

Anaesthesia will be induced with propofol (1.0-2.5 mg/kg), remifentanil (1 mcg/kg over minimum of 30s) and rocuronium (0.6mg/kg) and subsequently maintained with remifentail (0.25 - 1 mcg/kg/min), and sevoflurane. During skin suture, 7.5 mg piritramid will be administered. No nitrous oxide will be administered.

No other narcotics, analgesics, or sedatives than those described herein will be allowed. In case the surgical procedure mandates the use of additional and/or other narcotics, analgesics, or sedatives it shall be up to the investigator to decide on further treatment. However, in such case the patient will not be randomized and will be regarded as screening failure.

Randomization of the study patient takes place post-surgery as soon as the patient is able to cooperate adequatey. Ability to cooperate is defined as successful VAS assessment. At this time point the patient will be randomized and assigned her/his final randomisation number. The final randomisation number will be a 4-digit number where the leftmost position indicating the type of knee surgery performed. Patient undergoing surgery for cruciate ligament repair will receive randomisation numbers starting at 1001, 1002, and so forth. Patients undergoing knee replacement surgery will receive randomisation numbers starting at 2001, 2002, and so forth.

The first infusion of the investigational medicinal product will be started immediately after randomization. PCA will be established as soon as possible after the start of the first infusion of the investigational medicinal product but not later than 30 min after the start of the first infusion of the investigational medicinal product. A one-way PCA device (Vygon PCA-System) will be used. The PCA system is independent from any power supply and therefore both safe and reliable. The PCA system contains 20 mg Hydal® (hydromorphone) in 50 mL solvent. The PCA system parameters are fixed to a single bolus volume of 0.5 mL thus delivering 0.2 mg hydromorphone per bolus which equates to 2.0 mg piritramide or 1.5 mg morphine. Lock-out period of the PCA system used is fixed to 5 min.

All bolus injections will be recorded and added to the cumulative analgesic doses delivered by PCA.

NeodolpasseExperimentalIn the Neodolpasse® arm patients receive two infusions over 30 minutes after fixation of the graft replacement and with a time interval of 8 hours each during the first 24 hours. Neodolpasse® Infusion Solution combines 75 mg (250 mL) of the NSAID diclofenac with 30 mg of the muscle-relaxant orphenadrine.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. PCA-use: Total dose of PCA alangetics required over the first 24 hours post-surgery. Measured in mg

    amount of pca analgetic administered

    Measured: within 24 hours

Secondary outcomes (1)
  1. VAS-Scale: Pain relief will be tracked during the infusion periods and until 48 hours after the surgical intervention by using a Visual Analogue Scale (VAS).

    visual analogue scales (VAS) pain measured The pain VAS is a unidimensional measure of pain intensity, used to record patients' pain pain severity. The VAS used is a straight horizontal line of fixed length 100 mm and pople scored their Pain 0-100.

    Measured: after 24 hours

Model description
Randomization of the study patient takes place pre-surgery. Successfully randomized patients will receive two infusions over 30 minutes after fixation of the graft replacement and with a time interval of 8 hours each during the first 24 hours postoperatively. All patients will be provided with a PCA device as postoperative rescue medication. Consequently the possibility of an inadequate postoperative pain treatment in the study patients is very low, also in the placebo group.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Neodolpasse and Diclofenac in people with Pain, Postoperative and Analgesic Adverse Reaction, run by Medical University of Vienna at 1 site in Austria.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 19 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 20 Mar 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Austria. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

PCA-use: Total dose of PCA alangetics required over the first 24 hours post-surgery. Measured in mg (time frame: within 24 hours). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03493490, which also lists 5 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Mar 2023.
