Anal Cancer Squamous Cell | Dietary Supplement: prebiotics in combination with probiotics | Phase 2 |
Study Type : | Interventional (Clinical Trial) |
Estimated Enrollment : | 75 participants |
Allocation: | Randomized |
Intervention Model: | Parallel Assignment |
Intervention Model Description: | Eligible patients who consent to participate in this study will be randomized 1: 1 in two groups: Group A or experimental and Group B or control |
Masking: | Double (Investigator, Outcomes Assessor) |
Masking Description: | The researchers will identify the patients through a unique number and through the initials of the name. Randomization will be simple and conducted independently by clinical trial support staff who are not participating in the study. The random sequence will be generated by computer program. |
Primary Purpose: | Treatment |
Official Title: | A Randomized Phase II Study of the Administration of Prebiotics and Probiotics During Definitive Treatment With Chemotherapy-radiotherapy for Patients With Squamous Cell Carcinoma of the Anal Canal (BISQUIT) |
Actual Study Start Date : | March 13, 2019 |
Estimated Primary Completion Date : | August 13, 2023 |
Estimated Study Completion Date : | February 11, 2024 |

Experimental: Prebiotics and probiotics group
This group will receive standard nutritional guidance from the institutional routine and prebiotics in combination with probiotics, starting one week before the start of Ch-RT and daily throughout the treatment up to 6 to 8 weeks post Ch-RT at the time of evaluation response (primary outcome).

Dietary Supplement: prebiotics in combination with probiotics
Administration of prebiotics in combination with probiotics before the start of Ch-RT
Other Name: Symbioflor |
No Intervention: Control group
This group will lead nutritionally based just before starting Ch-RT.

- Response rate (clinical and radiological) [ Time Frame: Six to eight weeks from the end of Ch-RT ]absence of visible disease at the clinical examination and magnetic resonance imaging (MRI) of the pelvis (or pelvic tomography, if contraindicated to MRI) and without disease at a distance, through tomography of the chest and abdomen.
- Metabolic response by 18-FDG PET-CT [ Time Frame: Six to eight weeks from the end of Ch-RT ]Comparing the mean pre-and post-Ch-RT volume-capture measurements of each patient at 6-8 weeks post Ch-RT
- Complete clinical and radiological response rate [ Time Frame: Six months ]defined as absence of disease visible to clinical and pelvic MRI (or pelvic tomography) exams and without disease at a distance, through tomography of the chest and abdomen;
- Progression / disease free survival [ Time Frame: through study completion, an average of 5 years ]defined as the time from day1 cycle 1 of Ch-RT treatment to local or remote relapse, or death from any cause, whichever occurs first.
- Proportion of patients without colostomy [ Time Frame: Twelve months ]Proportion of patients without colostomy 12 months after Ch-RT termination.
- Incidence of Adverse Events Treatment-related [ Time Frame: through study completion, an average of 5 years ]Adverse events of grade 2 or higher by the Common Adverse Event Toxicity Criteria (CTCAE) version 4.0.
- Incidence of HPV in tumor tissue [ Time Frame: through study completion, an average of 3 years ]Incidence of positivity for HPV screening in tumor tissue through genotyping
- Variation of systemic immune parameters [ Time Frame: through study completion, an average of 3 years ]Defined by variation in total number of lymphocytes, neutrophil / lymphocyte ratio (NLR) and lymphocyte / monocyte ratio (LMR)
