NCT05726786

Brief Summary

The goal of this clinical trial research study is to evaluate the impact of preoperative oral immunonutrition (IN) on post-operative complications in patients undergoing a cystectomy. As a secondary focus, this study will aim to develop a signature that would identify patients that would benefit the most from IN. This is a multicentric (Swiss: N=3), prospective, controlled, pragmatic, parallel-group comparative study with block randomization stratified by centers.

Outcome Measures

Primary Outcomes (1)

  • Infectious complication after cystectomy

    Determination of infectious complications rate at 30 days after surgery (pneumonia, urinary tract infection, surgical site infection, sepsis, shock).

    30-days afetr surgery

Secondary Outcomes (4)

  • Comprehensive Complication Index (CCI)

    30 and 90 days after surgery

  • Mortality rate

    30 and 90 days after surgery

  • Complication-free survival rate

    90-days after surgery

  • Treatment compliance rate

    Between Day -30 and Day -10 and at preoperative admission after intake of the allocated nutrition (Day -1)

Other Outcomes (3)

  • Cancer-specific survival rate

    Postoperative time

  • Quality of life assessment

    30 and 90 days after surgery

  • Identification of biomarkers predictive of postoperative complications

    Before and after immunonutrition treatement

Study Arms (2)

Immunonutrition

EXPERIMENTAL

Seven days of preoperative oral supplementation with an immune-enhanced oral nutrition

Drug: Immunonutrition

No immunonutrition (control)

NO INTERVENTION

Standard of care

Interventions

Immunonutrition: Oral Impact®, Nestlé Health Science, Switzerland. IN will be administered as per manufacturer suggestion, i.e. three times a day during 7 days preoperatively. Oral Impact® is a powdered oral feed that provides 309 kcal/bag

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Patient undergoing open cystectomy (for all reasons)
  • Age ≥18 years
  • Ability and willingness to provide informed consent documented by signature

You may not qualify if:

  • Contraindications to IN, e.g. known hypersensitivity or allergy to lactose, fish oil or soy lecithin
  • Severe diarrhoea requiring medical attention
  • Current treatment with any immunosuppressive drug
  • In standard practice, pregnant or lactating women are systematically rejected by the surgeon for this surgical procedure. Furthermore, during the pre-surgical anaesthesia consultation, the eligibility of each patient for anaesthesia will be assessed according to the usual criteria and recommendations of the anaesthesia service of the CHUV
  • Other clinically significant concomitant disease affecting immunity (e.g., severe renal failure, HIV, SLE, transplant recipient, ...)
  • Inability to follow the procedures of the study, e.g. due psychological disorders, dementia, etc.
  • Participation in another study with investigational drug within the 30 days preceding and during the present study
  • Previous enrolment into the current study
  • Use of IN independently of the study
  • Enrolment of the investigator, his/her family members, employees and other dependent persons
  • Emergency procedure (less than 7 days between screening and surgery)
