Safety & Efficacy of Durvalumab+Neoadjuvant Chemotherapy for High-risk Urothelial Carcinoma of the Upper Urinary Tract
Safety & Efficacy of Neoadjuvant Immunotherapy With Durvalumab (MEDI 4736) Combined With Neoadjuvant Chemotherapy (Gemcitabine/Cisplatin or Gemcitabine/Carboplatin) in Patients With Operable, High-risk, Localized Urothelial Carcinoma of the Upper Urinary Tract
Following radical nephrectomy (RNU) for upper tract urothelial carcinoma (UTUC) most patients face a poor prognosis. Indeed, patients who have undergone RNU for UTUC have 5-year recurrence-free and cancer specific survival probabilities of 69% and 73% respectively. The primary objective of this study is to assess the pathological complete response rate to combination therapy with neoadjuvant durvalumab and chemotherapy (Gemcitabine/Cisplatin) before surgery in patients with high-risk, localized, non-metastatic urothelial carcinomas of the upper tract.
Following radical nephrectomy (RNU) for upper tract urothelial carcinoma (UTUC) most patients face a poor prognosis. Indeed, patients who have undergone RNU for UTUC have 5-year recurrence-free and cancer specific survival probabilities of 69% and 73% respectively. Additional systemic therapy therefore seems justified for prolonged cancer control. However, there have been very few studies on neoadjuvant/adjuvant therapies in UTUC. Recently, the UK's multicentric POUT trial reported the benefits of adjuvant chemotherapy in UTUC patients. Level 1 evidence has been provided for neoadjuvant therapy for urothelial carcinoma of the bladder via meta-analysis in 2005 but there are also several arguments for systemic therapy in this context especially as most patients lose the function of one kidney and cannot receive nephrotoxic cisplatin-based chemotherapy. Urothelial carcinoma of the upper tract have a different genetic background from carcinomas of the lower tract. The investigators hypothesized that there would be a greater occurrence of lower pathological stages among study group patients who receive neoadjuvant combined Durvalumab/Gemcitabine/Cisplatin or Carboplatin prior to RNU compared to the current literature (Gregg et al. 2018, Almassi et al. 2018). The primary objective is to assess the pathological complete response rate (ypT0) in each cohort and independently of a combination therapy with neoadjuvant durvalumab and chemotherapy (Gemcitabine/Cisplatin) before surgery in patients with high-risk, localized, non-metastatic urothelial carcinomas of the upper tract.Secondary objectives include: assessing partial response rate to treatment, assessing the safety and tolerability of the treatment and evaluating the overall survival, bladder recurrence and dissemination at two years of follow-up.

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. - 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.

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.
