• Current or prior use of immunosuppressive medication within 14 days before the first dose of the study intervention is excluded. The following are exceptions to this criterion: a) Intranasal, inhaled, topical steroids, or local steroid injections (eg, intraarticular injection); b) Steroids as premedication for hypersensitivity reactions (eg, CT scan premedication or chemotherapy premedication) or a single dose for palliative purpose (eg, pain control).
• For sub-study 4, participants are ineligible if they have received any anti-cancer therapy within 28 days prior to the first dose of study intervention or within 5 half-lives of the respective agent, whichever is longer.
• Any concurrent chemotherapy except study intervention, radiotherapy, investigational, biologic, or hormonal therapy for cancer treatment.
• Radiotherapy treatment with a wide field of radiation or to more than 30% of the bone marrow within 4 weeks, prior to the first dose of study intervention.
• Major surgical procedures within 4 weeks prior to the first dose of the study intervention or still recovering from prior surgery.
• Receipt of live attenuated vaccine within 30 days prior to the first dose of the study intervention.
• For sub-study 4, brain metastases unless asymptomatic, stable, and not requiring steroids for at least 14 days prior to start of study intervention. For sub-study 5, participants with untreated or progressive brain metastases.
• Have not recovered (ie, ≤ Grade 1 or at baseline) from an AE due to a previously administered anti-cancer therapy.
• For sub-study 4, participants have contraindications to any of the following drugs: 5- FU, paclitaxel and carboplatin
• History of another primary malignancy except for a) Malignancy treated with curative intent with no known active disease ≥2 years before the first dose of study intervention and of low potential risk for recurrence; b) Adequately treated nonmelanoma skin cancer or lentigo maligna, or carcinoma in situ without evidence of disease.
• History of active primary immunodeficiency or active or prior documented autoimmune or inflammatory disorders.
• Participants who are candidates for curative therapy.

Other illness
