The randomized clinical trial protocol is a multi-purpose document. It not only provides guidance for the conduct of trial to the investigators, but it also makes ethics committees and institutional review boards aware of appropriate measures adopted to protect participants&#8217; safety and interests. A proper design is crucial for the success of a clinical trial. It is often noted that the design of a trial is connected with its successes/failures8.

Parenteral nutrition is an essential component of overall therapy for a wide spectrum of indications, such as major gastrointestinal surgery, transient enteral intolerance, severe burns, coma; or for use in critically ill patients. Improvements in intravenous (IV) nutritional formulations and knowledge advancement regarding the implementation of therapy allow the safe and clinically efficacious administration of IV nutrition. These characteristics are particularly important in a metabolically stressed patient1.
Parenteral nutrition is commonly administered to patients by mixing nutrients that are compounded in the hospital pharmacy. Compounding total parenteral nutrition solutions from individual components is a multi-step, time-intensive process associated with a greater risk of human error. Recently, triple-chamber bag (3CB) systems have been developed in which individual components are separated by nonpermanent breakable seals. The contents of a 3CB include a glucose solution, an amino-acid solution, a lipid emulsion, with or without electrolytes. Prior to administration, the seal separating the various components of the 3CB is broken, enabling the components of the chambers to be admixed. The advantages offered by the 3CB includes increased physio-chemical shelf life of components, reduction the extent of contamination during preparation, and cutting down on the steps required in the preparation of a PN product2.
Lipid emulsion is an important ingredient in a PN formula; it can produce different clinical effects, depending upon the constituent fatty acids. Soybean-oil-based lipid emulsions primarily consist of long-chain linoleic acid (&#969;-6 polyunsaturated fatty acid [&#969;-6 PUFA]), which is mainly proinflammatory. Experimental data suggest that &#969;-6 PUFA-rich lipid emulsions may amplify the inflammatory response during stress and traumatic conditions, as well as increasing the infection rate3. On the other hand, olive-oil-based lipid emulsions, which consist of long-chain oleic acid (&#969;-9 monounsaturated fatty acids, [&#969;-9 MUFAs]), have a neutral response on the immune system3,4. Substituting soybean-oil-based &#969;-6 PUFAs with olive-oil-based &#969;-9 MUFAs can make the PN safe and further widen its clinical application5,6. However, there are limited clinical data in this connection.
Therefore, the present study aims to evaluate the rate of infections in two different lipid emulsions that varied in the content of linoleic acid, in addition to having the primary objective of assessing the safety and efficacy of 3CBs compared to CoBs for delivering PN. The assessment was carried out in adult hospitalized patients scheduled to undergo surgery for whom enteral nutrition was either not possible, inadequate, or inadvisable.

a clinical trial assessing the safety, efficacy, and delivery of olive-oil-based three-chamber bags for parenteral nutrition

Limited evidence exists to precisely estimate efficacy and safety differences between parenteral nutrition (PN) prepared using olive-oil-based three-chamber bags (3CBs) and soybean-oil-based compounded bags (CoBs) in hospitalized adult patients. We designed a multicenter, randomized, prospective, open-label, noninferiority protocol to compare the efficacy, safety, and distribution of olive-oil-based 3CBs and soybean-oil-based CoB formulations in adult Chinese patients requiring PN during surgical intervention. Subjects were randomized to receive either one of the study treatments using an interactive voice or web-based recognition system in accordance with the randomization code. Randomization was further stratified based on the study site and surgical category. Both treatment groups received similar amounts of calories and protein. In addition, the two study treatments contained a similar composition of the amino-acid component. The only difference between the two PN formulations was the lipid constitution. The duration of administration of study treatments was a minimum of 5 days up to a maximum of 14 days after the surgical procedure. The primary efficacy endpoint was serum prealbumin levels on day 5 of the study. Noninferiority was proved if the anti-log of the lower bound of the 95% confidence interval (CI) of the treatment difference was at least 0.80. Other efficacy measures included treatment preparation time; duration to achieve tolerability of oral nutrition; associated infectious complications; length of hospitalization; and laboratory assessment of markers of nutrition, inflammation, metabolism, and oxidative stress. A total of 458 patients were enrolled in the study. The results showed that olive-oil-based 3CBs were non-inferior to soybean-based CoBs, besides being well tolerated. The infection rate was found to be significantly lower in the olive-oil-based 3CB group. Thus, this study may be used as a reference for future research on lipid emulsion and 3CBs.

Patient Disposition 
Out of the 480 patients who gave their consent, a total of 458 patients were enrolled and randomized in the study. The ITT population included all randomized patients, of whom 226 constituted the test group and 232 the control group. The safety population included a total of 453 patients, of whom 222 belonged to the test group and 231 to the control group. The modified intention-to-treat (mITT) population comprised a total of 443 patients, of whom 219 were in the test group and ...

A Clinical Trial Assessing the Safety, Efficacy, and Delivery of Olive-Oil-Based Three-Chamber Bags for Parenteral Nutrition

Here, we present a protocol for a study comparing the efficacy, safety, and delivery of olive-oil-based 3CB and soybean-oil-based CoB formulations in adults requiring parenteral nutrition. The results revealed that olive-oil-based 3CBs is non-inferior and well tolerated compared to soybean formulations.
