imaging day pre-visit requirements, and has read, signed, and dated an informed consent form prior to any study procedures being performed.\n* The subject is male or female, ≥18 years of age.\n* Subject has a life expectancy ≥12 weeks.\n* Subject has Eastern Cooperative Oncology Group (ECOG) performance status 0-1.\n* Subject has an unresectable or metastatic solid tumour or a local and resectable head and neck squamous cell carcinoma, or an unresectable stage III-IV melanoma.\n* Subject is eligible for ICI treatment per Investigator judgement.\n* Subject has at least 1 measurable tumour lesion documented on CT\u002Fmagnetic resonance imaging (MRI) RECIST v1.1 during the last 12 months.\n* Subject has a tumour lesion(s) of which a biopsy can safely be obtained according to standard clinical care procedures.\n* Subject is male or female that agrees to adhere to the protocol contraception methods.\n\nExclusion Criteria:\n\n* Subject is unable to undergo all procedures in the study and\u002For is unable to remain still and tolerate the imaging procedure.\n* Subject has 12-lead ECG significant findings during screening, per Investigator's assessment.\n* Subject is not stable due to medical condition or therapy that, in the opinion of the Investigator, could compromise subject safety or protocol objectives.\n* Subject has active autoimmune disease or a documented history of autoimmune disease or syndrome that requires systemic steroids or immunosuppressive agents.\n* Subject has serious non-malignant disease or conditions that, in the opinion of the Investigator, could compromise subject safety or protocol objectives.\n* Subject has B or T cell lymphoma.\n* Subject has brain or bone-marrow metastasis that, in the opinion of the Investigator, could compromise subject safety or protocol objectives.\n* Subject has signs or symptoms of systemic infection within 2 weeks prior to imaging day.\n* Subject has history of severe allergic, anaphylactic, or other hypersensitivity reactions to chimeric or humanised antibodies or fusion proteins or known allergy to the study IMP ingredients and\u002For the proposed ICI therapy.\n* Subject has any other diseases, metabolic dysfunction, physical examination finding, or clinical laboratory finding giving reasonable suspicion of a disease or condition that contraindicates the use of the ICI treatment, or that may affect the interpretation of the results or render the subject at high risk from complications.\n* Subject has laboratory values out of range per protocol.\n* Subject has any safety laboratory test results (blood chemistry, haematology, and urinalysis) that, in the opinion of the Investigator, could compromise subject safety or protocol objectives.\n* Subject has had any major surgery within 4 weeks prior to enrollment.\n* Subject has been enrolled in another interventional clinical study within the 30 days before screening for this study, except for the study site IIS.\n* Subject is pregnant or planning to become pregnant or is breastfeeding.\n* Subject has a history of alcohol or drug abuse within the last year.\n* Subject has had treatment with systemic immunostimulatory agents within 6 weeks or 5 half-lives of the drug, whichever is shorter, prior to dosing with the IMP.\n* Subject has had treatment with systemic immunosuppressive medications within 2 weeks prior to dosing with the IMP.\n* Subject has received acute, low-dose, systemic immunosuppressant medications that, in the opinion of the Investigator, could compromise protocol objectives.\n* Subject has used systemic corticosteroids to treat inflammatory or autoimmune symptoms.","ALL","18 Years",{"count":109,"type":110},50,"ESTIMATED","INTERVENTIONAL",[113],"PHASE1","Part A: The purpose
