Abstract 4310

Background

mSCPC is an orphan disease with a poor prognosis. First line systemic treatment relies on platinum-based polychemotherapies (PBPC). These combinations remain poorly effective with median progression-free survival (PFS) and overall survival (OS) around 7.5 months and 16 months respectively [Pagliaro 2010; Nicholson 2013]. SCPC is a disease with a virally induced oncogenesis, moreover PD-L1 is commonly expressed with an expression rate of 62.2% in primary tumours and a strong correlation between PD-L1 in the primary tumour and metastases [Udager 2016]. Immunotherapies targeting the PD-1/PD-L1 axis are effective in other squamous cell or HPV related cancers. There is no consensus on a second line systemic treatment in mSCPC. Tumour mass is assumed to be reduced as a result of the first line chemotherapy. PBPC are known to be able to trigger immunogenic cell death. The maintenance strategy after systemic chemotherapy which has controlled the disease is a validated concept in many tumour models. Maintenance treatment with immunotherapy after initial PBPC may help to maintain disease control in mSCPC setting.

Trial design

PULSE trial is a prospective multicenter open label phase II study that will enroll 32 patients. Patients with unresectable locally advanced or metastatic SCPC must have carried out a radiological assessment showing a non-progressive disease after 3 to 6 cycles of a first line PBPC. Patients previously treated by an immunotherapy are excluded. A minimal period of 3 weeks washout after chemotherapy is required before starting intravenous maintenance Avelumab. It will be administered every two weeks at the dose of 10mg/kg until progression or unacceptable toxicity. The primary objective is to assess PFS according to RECIST 1.1 criteria. Secondary objectives are overall survival, impact of PL-L1 expression, safety, quality of life. Exploratory endpoints include blood immune-response monitoring, correlation of tumour immune infiltrate and PD-L1 expression on PFS. Screening across ∼15 sites in France is being conducted with first site initiated in February 2019.
