* Primary tumor and/or metastasis amenable for partial/total surgery or tap
* Measurable or evaluable disease according to RECIST 1.1 criteria
* Patients age ≥ 18 years
* WHO performance status 0-2
* Adequate hematological values: neutrophils ≥1x10\^9/L, platelets ≥70x10\^9/L
* Adequate hepatic function: bilirubin ≤2 x ULN; AST and ALT and AP ≤2.5 x ULN (except for patients with liver metastasis: ≤5 x ULN)
* Adequate renal function (creatinine clearance \>40mL/min/1.73m\^2, calculated according to the corrected formula of Cockcroft-Gault
* Women with child-bearing potential are using effective contraception, are not pregnant and agree not to become pregnant after pre-registration, during trial treatment and during the 6 months thereafter. A negative blood pregnancy test before inclusion into the trial is required for all women with child-bearing potential
* Men agree not to father a child during trial treatment and during 6 months thereafter

Exclusion Criteria for pre-registration:

* Known or suspected CNS metastases or active leptomeningeal disease

* Participated in any other investigational study or received an experimental therapeutic procedure considered to interfere with the study in the 4 preceding weeks of the pre-registration
* Concomitant use of other anti-cancer drugs
* Planned radiotherapy (other than symptom control)

* History of cerebrovascular accident or intracranial hemorrhage within 6 months prior to pre-registration
* Any history of HIV
* Known history of HTLV-1, HTLV-2, or active chronic Hepatitis C or Hepatitis B Virus infection or any uncontrolled active systemic infection requiring intravenous (iv) antimicrobial treatment
* Known severe allergy to reagents in the study product (MVX-ONCO-1)
* Systemic disease other than cancer that is not controlled by approved medication
* Patient with active autoimmune disease
* Chronic immunosuppressive treatment exceeding 20 mg/day of prednisone or an equivalent corticosteroid. Note: In acute situations prednison exceeding 20mg/day or equivalent(day is allowed during 7 days)
* Women who are pregnant or breast feeding
* Any other serious underlying medical, psychiatric, psychological, familial or geographical condition, which in the judgment of the investigator may interfere with the planned staging, treatment and follow-up, affect patient compliance or place the patient at high risk from treatment-related complications

* Adequate renal function (creatinine clearance \>40 mL/min/1.73m\^2, calculated according to the corrected formula of Cockcroft-Gault
* Women with child-bearing potential are using effective contraception, are not pregnant or lactating and agree not to become pregnant after registration, during trial treatment, and during the 6 months thereafter. A negative blood pregnancy

Exclusion criteria for registration:

* Known or suspected CNS metastases or active leptomeningeal disease
* Concomitant use of other anti-cancer drugs
