ClinConnect Summary

This clinical trial is investigating a combination of a medication called durvalumab and chemotherapy (specifically Gemcitabine and Cisplatin) to see how effective it is before surgery for patients with high-risk urothelial carcinoma of the upper urinary tract. The goal is to find out how many patients have no signs of cancer in their tissue samples after receiving this treatment prior to their surgery. This study is important because patients with this type of cancer often face a challenging prognosis after surgery.

To be eligible for this trial, participants need to be at least 65 years old, have a confirmed diagnosis of high-grade urothelial carcinoma, and meet certain health criteria. They should not have received previous treatments for their cancer and must be able to provide informed consent. If you join the trial, you can expect to receive the combination therapy before your surgery, along with regular monitoring and assessments to evaluate your response to the treatment. It’s also important to note that both men and women who are capable of becoming pregnant will need to use effective birth control during the study.

Eligibility criteria

• Inclusion Criteria:
• • Patient has been correctly informed and has given signed consent.
• • Patient is covered by a health insurance scheme.
• • Patients aged over 70 must have a G8 score (Soubeyran et al. 2014) of at least 14.
• • Patient's body weight must be over 30kg
• • Patient has high-grade urothelial carcinoma of the renal pelvis or ureter confirmed histologically (uteroscopic biopsy) or cytologically (urine cytology).
• • Presence of divergent histologies (i.e. squamous cell tumour, adenocarcinoma, small cell carcinoma, micropapillary variant) may also give rise to inclusion if there is a high prevalence (over 90%) of a urothelial component.
• • Presence of EITHER high-grade disease on the uteroscopic tumor biopsy
• • OR Presence of high-grade disease on urine cytology AND infiltrative aspect of renal pelvis/ ureteral wall on the CT scan (presence of hydronephrosis will be considered invasive by definition) with negative cystoscopy.
• • Or in the absence of histological evidence, the opinion of the multidisciplinary consultation meeting (RCP) will prevail for the analysis of the imaging and the potential inclusion of the patient in the study
• • No prior systemic therapies.
• • ECOG performance status 0 to 1.
• • M0 No or N1 disease on CT scan.
• * Required initial laboratory values :
• • Absolute neutrophil count of over 1500 cells/mm²
• • Platelet count of over 100,000 cells/mm3
• • Hemoglobin over 9.0 g/dL
• • Bilirubin below 1.5 times the Upper Limit of Normal for the institution
• • Aspartase transaminase (ASAT) and Alanine transaminase (ALAT) below 2.5 x the Upper Limit of Normal for the institution.
• • Alkaline phosphatase below 2.5 times the Upper Limit of Normal for the institution
• • INR and aPTT below 1.5 times the Upper Limit of Normal for the institution.
• • For Cohort 1 : An estimated glomerular filtration rate of over 60ml/min/1.73m² using the CKD-EPI and/or MDRD equation.
• • For Cohort 2 : An estimated glomerular filtration rate of 40ml to 60ml/min/1.73m² using the CKD-EPI and/or MDRD equation.
• • Patients with reproductive potential must use an effective method to avoid pregnancy for the duration of the trial.
• • Patients must have a life expectancy of at least 12 weeks.
• Exclusion Criteria:
• • The patient is participating in another interventional trial;
• • or is in an exclusion period determined by a previous study;
• • or is under judicial protection, or is an adult under guardianship
• • or refuses to sign the consent;
• • or it is impossible to correctly inform the patient.
• • The patient is pregnant or breastfeeding.
• • Concomitant diagnosis of muscle invasive or in situ or high grade non muscle invasive urothelial carcinoma of the bladder.
• • Evidence of NYHA functional class III or IV heart disease.
• • Serious intercurrent medical or psychiatric illness, including serious active infection.
• • Concomitant use of any other investigational drugs.
• • Diagnosis of immunodeficiency or received systemic steroid therapy or any other form of immunosuppressive therapy within 7 days prior to study registration.
• • Additional malignancy within last 5 years. Exceptions include basal cell carcinoma of the skin, squamous cell carcinoma of the skin, in situ cervical cancer that has undergone potentially curative therapy, stable (as defined by PSA change, checked within 30 days) and untreated very low-risk or low-risk prostate cancer defined by current NCCN guidelines. Previous or concomitant history of non-muscle invasive bladder cancer is acceptable.
• • Active autoimmune disease requiring systemic treatment within the past 3 months or a documented history of clinically severe autoimmune disease, or a syndrome that requires systemic steroids or immunosuppressive agents. NOTE: Subjects with vitiligo or resolved childhood asthma/atopy would be an exception. Subjects that require systemic corticosteroids at physiologic doses not exceed 10mg/day of prednisone or its equivalent would not be excluded from the study. Subjects that require intermittent use of bronchodilators or local steroid injections would not be excluded from the study. Subjects with hypothyroidism stable on hormone replacement or Sjogren's syndrome will not be excluded from the study.
• • History of Human Immunodeficiency Virus (HIV) (HIV 1/2 antibodies).
• • Active infection including tuberculosis (clinical evaluation that includes clinical history, physical examination and radiographic findings, and TB testing in line with local practice), hepatitis B (known positive HBV surface antigen (HBsAg) result), hepatitis C.
• • Live vaccine received within 30 days prior to the first dose of trial treatment.
• • Major surgical procedure (as defined by the Investigator) within 28 days prior to the first dose of treatment. Note: Local surgery of isolated lesions for palliative intent is acceptable.
• • History of allogenic organ transplantation.
• • Uncontrolled intercurrent illness, including but not limited to, on-going or active infection, symptomatic congestive heart failure, uncontrolled hypertension, unstable angina pectoris, cardiac arrhythmia, interstitial lung disease, serious chronic gastrointestinal conditions associated with diarrhoea, or psychiatric illness/social situations that would limit compliance with study requirement, substantially increase risk of incurring AEs or compromise the ability of the patient to give written informed consent
• • Female patients who are pregnant or breastfeeding or male or female patients of reproductive potential who are not willing to employ effective birth control from screening to 90 days after the last dose of durvalumab monotherapy.
