Overview
A Prospective Phase II Study of Adjuvant Cisplatin-Based Chemotherapy followed by Maintenance Avelumab in Upper Tract Urothelial Carcinoma
Description
Upper tract urothelial carcinoma (UTUC), including those that arise in the renal pelvis or in ureter, are relatively uncommon but highlyinvasive. Although radical surgery followed by adjuvant chemotherapy is considered a standard in the management of UTUC, a significant percentage of patients experience recurrence, leading to a poor prognosis. Nivolumab has been investigated for adjuvant treatment in the other trial, but unfortunately, a better DFS was not observed in patients with UTUC. Given the promising efficacy of the maintenance avelumab following first-line chemotherapy, the maintenance strategy looks promising in the adjuvant setting of curatively-resected UTUC.
Eligibility
Inclusion Criteria:
* Must be aged 19 years or more
* Must have histologically or cytologically proven UTUC arising from renal pelvis and/or ureter.
* Must have histological evidence of high-risk muscle-invasive disease (i.e., pT2\~ T4) and/or N+ disease.
* Must have an ECOG performance status of 0 to 1
* Received at least 3 or 4 cycles of adjuvant cisplatin-based chemotherapy, and proved to have no evidence of disease recurrence with imaging studies, urine cytology and cystoscopy
* At least 3 weeks since the last surgical procedures or chemotherapy prior to enrolment. Subjects must have recovered to \ Grade 2 neuropathy or evidence of unstable neurological symptoms within 4 weeks of Cycle 1 Day 1
* Major surgery, other than diagnostic surgery or transurethral resection, within 4 weeks prior to Cycle 1 Day 1, without complete recovery
* Double primary cancer of other site(s) or a history of other malignancies, except for cured ones at the discretion of investigator
* Active, uncontrolled bacterial, viral, or fungal infections, requiring systemic therapy.
* Subjects who have exhibited allergic reactions to study treatment.
* Concomitant disease or condition that could interfere with the conduct of the study, or that would, in the opinion of the Investigator, pose an unacceptable risk to the subject in this study.
* Subject with legal incapacity or limited legal capacity. Dementia or significantly altered mental status that would limit the understanding or rendering of informed consent and compliance with the requirements of this protocol. Unwillingness or inability to comply with the study protocol for any reason.
* Current use of immunosuppressive medication, EXCEPT for the following: a. intranasal, inhaled, topical steroids, or local steroid injection (e.g., intra-articular injection); b. Systemic corticosteroids at physiologic doses ≤ 10 mg/day of prednisone or equivalent; c. Steroids as premedication for hypersensitivity reactions (e.g., CT scan premedication). 12) Active autoimmune disease requiring systemic immunosuppressive treatment. Patients with controlled autoimmune disease not requiring systemic immunosuppressive treatment including diabetes type I, vitiligo, psoriasis, or hypo- or hyperthyroid diseases not requiring immunosuppressive treatment are eligible.
* Prior organ transplantation including allogenic stem-cell transplantation.
* Vaccination within 4 weeks of the first dose of avelumab and while on trials is prohibited except for administration of inactivated vaccines.
* Persisting toxicity related to prior therapy (NCI CTCAE Grade \>
1); however, alopecia, sensory neuropathy Grade ≤ 2, or other Grade ≤ 2 not constituting a safety risk based on investigator's judgment are acceptable.
* Lactating Women Must discontinue breastfeeding during study treatment and for at least 30 days after administration of the final dose of study drug.
