Clinical Trial Summary

Most of Colorectal cancer (CRC) diagnosed are candidates for surgical resection with curative intent, although colorectal surgery is associated with some complications that could be life-threatening. Antibiotic prophylaxis is commonly used prior to the admission for the prevention of postoperative complications. However, this intervention can change the composition of intestinal microbiota and promote adverse inflammatory outcomes in CRC patients after surgery.

It seems the combination of different fungal extracts could be beneficial because of their role in gut microbiota modulation and their anti-inflammatory activity. Therefore, the fungal extract nutraceutical MICODIGEST 2.0 could be used to reduced the complications after CRC surgery.

Based on this hypothesis, we have designed a double-bind randomized clinical trial to evaluate the effect of MICODIGEST 2.0 on the complications after surgery with curative intent for CRC.

Description:

Colorectal cancer (CRC) is one of the most common malignancies in western countries. Most of the CRC diagnosed are candidates for surgical resection with curative intent. Cure rates after surgery vary between 92 % and 67 % depending on the tumor stage. However, colorectal surgery is associated with some complications that could be life-threatening.

Antibiotic prophylaxis is commonly used prior to the admission for the prevention of this postoperative complications. Several studies have shown that antibiotic administration reduces the risk of infections associated with surgery. Nevertheless, this intervention does not modify the mortality and severity of other complications detected. Further, antibiotic prophylaxis could change the intestinal microbiota and promote adverse inflammatory outcomes in CRC patients after surgery.

Fungal polysaccharides have attracted attention because of their role in gut microbiota modulation. It seems that this type of polysaccharides could reduce pathogen levels and stimulate the growth of beneficial microorganism. Anti-inflammatory activity has also been described for these fungal polysaccharides. It seems the combination of different fungal extracts would send multiple stimuli to the immune system increasing intracellular reactions and interactions. Thus, the fungal extract nutraceutical MICODIGEST 2.0 could be used to reduced the complications after CRC surgery. MICODIGEST 2.0 is available since 2016 without any adverse effect reported.

For all these reasons we have designed a double-bind randomized clinical trial to evaluate the effect of MICODEGIST 2.0 on the complications after surgery with curative intent for CRC.

Apart from this purpose, we have also set the following secondary objectives:

• To evaluate the safety of MICODIGEST 2.0 in CRC patients.

• To evaluate the effect of MICODIGEST 2.0 on feal microbiome composition and diversity.

• To evaluate the effect of MICODIGEST 2.0 on inflammatory pattern, dietary pattern and quality of life.

• To analyze the effect of microbiome, inflammatory and dietary pattern on complications after surgery.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Rate of complications.	Anastomotic failure, infection, prolonged ileus, systemic complications and other will be measured. Clavien-Dindo classification will be used for grading the severity of these postoperative complications. These analysis will be measured to evaluate the effect of MICODEGIST 2.0 on the complications after surgery with curative intent for CRC.	week 4-6
Secondary	Frequency of adverse effects.	Adverse effects will be considered during follow-up and after surgery using Common Terminology Criteria for Adverse Events (CTCAE) v5.0. This analysis will be measured to evaluate the safety of MICODIGEST 2.0 in CRC patients.	week 1-6
Secondary	Fecal microbiome composition.	High-quality DNA extraction will be performed in fecal samples. The bacterial 16S ribosomal ribonucleic acid gene will be sequencing on an Illumina MiSeq. Metagenomic species and a database with >200.000 strains will be used to define the microbiome composition. This analysis will be used to evaluate the effect of MICODIGEST 2.0 on feal microbiome composition.	week 4-6
Secondary	Neutrophil/Lymphocyte ratio.	Neutrophil/Lymphocyte will be measured dividing the absolute number of neutrophils by the absolute number of lymphocytes from peripheral blood sample. This inflammatory biomarker will be used to evaluate the effect of MICODIGEST 2.0 on inflammatory pattern.	week 4-6
Secondary	C reactive protein (CRP) level.	CRP levels (mg/dL) from peripheral blood samples will be measured to evaluate the effect of MICODIGEST 2.0 on inflammatory pattern.	week 4-6
Secondary	Tumor Necrosis Factor alpha (TNF-alpha) and interleukin-6 (IL-6) levels.	TNF-apha (pg/mL) and IL-6 (pg/mL) from peripheral blood samples will be measured to evaluate the effect of MICODIGEST 2.0 on inflammatory pattern.	week 4-6
Secondary	Dietary pattern assessment.	Patient-Generated Subjective Global Assessment survey (PG-SGA) will be used to assess the nutritional status. At the end of this survey, the patient will be rated nutritionally in one of three categories: "Well-nourished or anabolic" (PG-SGA - A), "Moderately or suspected of being undernourished" (PG-SGA B) and "Severely undernourished" (PG-SGA C). This analysis will be performed to evaluate the effect of MICODIGEST 2.0 on dietary pattern.	week 4-6
Secondary	Quality of life assessment.	The 36-item Short Form Health Survey (SF-36) will be used to measure the health-related quality-of-life. The SF-36 is a 36-item patient-reported questionnaire that covers eight health domains. Scores for each domain range from 0 to 100, with a higher score defining a more favorable health state. This analysis will be perfomed to evaluate the effect of MICODIGEST 2.0 on quality of life.	week 4-6
