At least 35 patients with measurable disease will be enrolled. Patients with no measurable disease and only widespread bone disease must have a CTC count of ≥5 cells per 7.5 mL of blood. 6. Availability of tumor tissue from a fresh biopsy at screening unless the biopsy cannot be obtained due to safety reasons or non-accessibility of the tumor site. If it is not possible to obtain a fresh biopsy, every effort should be taken to retrieve an archival biopsy. Archived, fixed tumor tissue may only be collected if taken preferentially after completion of the most recent systemic tumor therapy and within 12 months prior to the first dose of study treatment. 7. Performance status: Eastern Cooperative Oncology Group (ECOG) performance score 0-1 8. Must have recovered from all AEs (except alopecia) due to previous therapies to grade ≤1 toxicity (excluding alopecia) or have stable grade 2 neuropathy Have adequate organ function as defined below. Specimens must be collected within 10 days prior to the start of study interventions. 9. Hematology: 9.1. Absolute neutrophil count ≥1500/µL 9.2. Platelets ≥100 000/µL 9.3. Hemoglobin ≥9.0 g/dL (criteria must be met without packed red blood cell transfusion within the prior 2 weeks; patients can be on a stable dose of erythropoietin [≥ 3 months]) 10. Renal function: Creatinine clearance as measured by glomerular filtration rate ≥30 mL/min using Cockcroft-Gault equation 11. Hepatic function: ALT/AST≤2.5× upper limit of normal (ULN) and total bilirubin ≤1.5×ULN or direct bilirubin ≤ ULN in patients without liver metastasis (benign hereditary hyperbilirubinemias). In patients with liver metastasis, ALT/AST ≤5×ULN is allowed but total bilirubin must be ≤2×ULN. 12. Prothrombin time and activated partial thromboplastin time ≤1.5×ULN 13. A locally performed hepatitis B (HBV) test is required during screening. Patients who are hepatitis B (HBV) surface antigen positive are eligible if they have received HBV anti-viral therapy for at least 4 weeks and have undetectable HBV viral load before study entry (ICF signature). 14. A locally performed hepatitis C (HCV) test is required during screening. Patients with history of hepatitis C (HCV) infection are eligible if HCV viral load is undetectable at screening. Patients must have completed anti-viral therapy at least 4 weeks before study entry (ICF signature). 15. A female patient is eligible to participate if she is not pregnant, not breastfeeding, and one of the following conditions applies: 15.1. Not a woman of childbearing potential (WOCBP). A WOCBP is defined as fertile, following menarche and until becoming post-menopausal unless permanently sterile. Permanent sterilization methods include hysterectomy, bilateral salpingectomy, and bilateral oophorectomy. A postmenopausal state is defined as no menses for 12 months without an alternative medical cause. A high follicle stimulating hormone level in the postmenopausal range may be used to confirm a post-menopausal state in women not using hormonal contraception or hormonal replacement therapy. However, in the absence of 12 months of amenorrhea, a single follicle stimulating hormone measurement is insufficient. 15.2. A WOCBP who agrees to use a highly effective contraceptive method during the treatment period and for at least 120 days after the last dose of pembrolizumab or at least 30 days after the last dose of nanrilkefusp alfa, whichever is later. •WOCBP can only be included after a negative serum pregnancy test at screening. •Highly effective contraception includes: oCombined (estrogen- and progestogen-containing) hormonal contraception associated with inhibition of ovulation:Oral; Intravaginal; Transdermal oProgestogen-only hormonal contraception associated with inhibition of ovulation:Oral;Injectable;Implantable 16. Male patients must agree to use a condom during the treatment period and for at least 120 days after the last dose of pembrolizumab or at least 30 days after the last dose of nanrilkefusp alfa, whichever is later.
