简要总结
This is a single-armed, single-centre, non-blinded phase II trial to assess efficacy of induction chemo-immunotherapy for resectable node-positive squamous cell carcinoma of the penis
详细描述
This is a phase II study in which fifty adult patients with cTxN1-3 locoregionally advanced squamous cell penile cancer (LRAPC), suitable for resection will be included. Patients with recurrence in lymph nodes are suitable for inclusion if they have not received prior systemic treatment. Patients with cN1 are only included in case of central nodal necrosis and/or an irregular nodal border, or node >3cm on CT. A maximum of 2 supraregional or distant metastases is allowed if local treatment (i.e. irradiation or resection) is feasible.
Patients will be treated with three 21-day cycles of induction chemotherapy, carboplatin AUC5 (max 750 mg) and paclitaxel 175 mg/m2, with additional fixed-dose 400mg pembrolizumab on the first and third cycle.
Response to induction therapy will be evaluated by CT scan, ca. 2 weeks after the last cycle.
Subsequent consolidative treatment will consist of surgical resection of all visible and/or suspected disease.
In 3-9 weeks after surgery, patients will enter the adjuvant phase, consisting of 7 cycles of pembrolizumab 400 mg every 6 weeks. Focused physical examination, registration of adverse-events and monitoring of, amongst others, TSH, FT4, liver enzymes via blood tests, is performed at the start of every cycle. End of treatment visit will be set 30 days after receiving the last cycle of pembrolizumab.

入选标准
- •The participant (or legally acceptable representative if applicable) provides written informed consent for the trial.

- •cTxN2-3 or
- •cTxN1 in case of central nodal necrosis and/or an irregular nodal border, or node >3cm, or
- •Inguinal or pelvic lymph node recurrence that is potentially resectable. Any of the disease stages above, in combination with oligometastatic disease with a maximum of 2 distant metastases is allowed, as long as these metastases can be treated by resection or radiotherapy. This should be established in the multidisciplinary tumor board before enrolment.
- •Archival tumor tissue sample or newly obtained [core, incisional or excisional] biopsy of a tumor lesion not previously irradiated has been provided. Formalin-fixed, paraffin embedded (FFPE) tissue blocks are preferred to slides. Newly obtained biopsies are preferred to archived tissue.
- •A male participant must agree to use a contraception as detailed in Appendix 3 of this protocol during the treatment period and for at least 180 days after the last dose of study treatment and refrain from donating sperm during this period.
- •Have an Eastern Cooperative Oncology Group (ECOG) performance status of 0 to
- •Evaluation of ECOG is to be performed within 14 days prior to the first dose of study intervention.
- •Have adequate organ function defined as: absolute neutrophil count (ANC) ≥1.5 10e9 /L, platelets ≥100 10e9/L; hemoglobin ≥9.0 g/dL or ≥5.6 mmol/L; creatinine ≤1.5 × ULN OR GFR>30 ml/min as per Cockcroft-Gault formula in patients with creatinine levels > 1.5x institutional ULN; total bilirubin 1.5 ×ULN OR direct bilirubin ≤ULN for participants with total bilirubin levels >1.5 × ULN; AST (SGOT) and ALT (SGPT) ≤2.5 × ULN; International normalized ratio (INR), prothrombin time (PT) OR activated partial thromboplastin time (aPTT) ≤1.5 × ULN unless participant is receiving anticoagulant therapy as long as PT or aPTT is within therapeutic range of intended use of anticoagulants. Specimens must be collected within 14 days prior to the start of study intervention.
排除标准
- •Has received prior therapy with an anti-PD-1, anti-PD-L1, or anti-PD-L2 agent or with an agent directed to another stimulatory or co-inhibitory T-cell receptor (eg, CTLA-4, OX-40, CD137).
- •Has received prior systemic anti-cancer therapy including investigational agents, or an investigational device, within 4 weeks prior to registration.
- •Has received prior radiotherapy within 4 weeks of start of study intervention or radiation-related toxicities requiring corticosteroids.
- •Has received a live vaccine or live-attenuated vaccine within 30 days before the first dose of study intervention. Administration of killed vaccines is allowed.
- •Has a diagnosis of immunodeficiency or is receiving chronic systemic steroid therapy (in dosing exceeding 10 mg daily of prednisone equivalent) or any other form of immunosuppressive therapy within 7 days prior to the first dose of study drug.
- •Known additional malignancy that is progressing or has required active treatment within the past 3 years.
- •Exceptions: Participants with basal cell carcinoma of the skin, squamous cell carcinoma of the skin or carcinoma in situ, excluding carcinoma in situ of the bladder, that have undergone potentially curative therapy are not excluded. Patients with low-risk prostate cancer (defined as Stage T1/T2a, Gleason score ≤ 6, and PSA ≤ 10 ng/mL) who are treatment-naive and undergoing active surveillance are eligible.
- •Has known active or treated CNS metastases and/or carcinomatous meningitis.
- •Has severe hypersensitivity (≥Grade 3) to pembrolizumab and/or any of its excipients.
- •Has active autoimmune disease that has required systemic treatment in the past 2 years except replacement therapy (eg., thyroxine, insulin, or physiologic corticosteroid). Patients with vitiligo, psoriasis or other mild skin disease can still be included.
- •Has a history of (non-infectious) pneumonitis/interstitial lung disease that required steroids or has current pneumonitis/interstitial lung disease.
- •Has an active infection requiring systemic therapy.
- •Has a known history of Human Immunodeficiency Virus (HIV) infection.
- •Concurrent active Hepatitis B (defined as HBsAg positive and/or detectable HBV DNA) and/or Hepatitis C virus (defined as anti-HCV Ab positive and detectable HCV RNA) infection. Hepatitis B and C screening tests are not required unless a patient has a known history of HBV or HCV infection. Participants must have completed curative anti-viral therapy at least 6 months prior to randomization.
- •Has not adequately recovered from major surgery or has ongoing surgical complications.
- •Major pelvic surgical procedure within 4 weeks prior to enrolment or anticipation of need for a major surgical procedure during the course of the study other than for the disease under study.
