In Part 1, subjects with advanced selected solid tumors will be enrolled. Subjects will be administered escalating doses of feladilimab and tremelimumab in combination. feladilimab will be administered every 3 weeks and tremelimumab will be administered every 3 weeks for 6 doses and every 12 weeks thereafter.

In Part 2, subjects with R/R HNSCC who have disease progression after receiving at least one platinum-based chemotherapy and at least one anti-PD-1/PD-L1 will be enrolled. Subjects will be administered feladilimab in combination with tremelimumab at recommended Phase 2 dose as determined from Part 1.

In Part 2, subjects with R/R HNSCC who have disease progression after receiving at least one platinum-based chemotherapy and at least one anti-PD-1/PD-L1 will be enrolled. Subjects will be administered a single agent SOC therapy of either paclitaxel, docetaxel or cetuximab as per the investigators choice.

feladilimab is humanized anti-ICOS agonist immunoglobulin G (IgG) 4 monoclonal antibody (mAb), which will be administered as an intravenous (IV) infusion once every 3 weeks.

Tremelimumab is humanized anti-CTLA-4 IgG2 mAb, which will be administered as an IV infusion once every 3 weeks for 6 doses, thereafter once every 12 weeks .

Docetaxel is a microtubule stabilizer which will be administered as an IV infusion once every 3 weeks at a dose of 75 milligrams per meter square (mg/m\^2).

GSK Clinical Trials

The purpose of this study is to evaluate if the combination of GSK3359609 and tremelimumab is safe and tolerable (Part 1) and provides significant survival benefit to subjects with relapsed/refractory (R/R) Head and Neck Squamous Cell Carcinomas (HNSCC) to warrant further clinical investigation (Part 2). Part 1 (dose escalation) will enroll subjects with advanced, selected solid tumors. Subjects will receive escalating doses of GSK3359609 and tremelimumab in combination in Part 1. Part 2 is randomized expansion and will enroll subjects with R/R HNSCC who have disease progression after receiving at least 1 platinum-based chemotherapy and at least 1 anti-programmed death receptor protein-1 (PD-1)/anti-programmed death-ligand 1 (PD-L1) therapy, whether in combination or separately. In Part 2, subjects will be randomized in a ratio of 2:1 to receive either GSK3359609 in combination with tremelimumab at the recommended Phase 2 dose or investigators choice of a single-agent standard of care (SOC) therapy including paclitaxel, docetaxel or cetuximab. The total duration of subjects in the study will be approximately 4 years.

In Part 1, dose escalation will occur using a zone based approach. Part 2 will be randomized, parallel group study wherein the subjects will be randomized in a ratio of 2:1 to either recommended Phase 2 dose combination of GSK3359609 and tremelimumab or SOC (paclitaxel, docetaxel or cetuximab).

IPD for this study will be made available via the Clinical Study Data Request site.

A DLT is considered by the investigator to be clinically relevant, attributed event within first 28 days of intervention meeting the following criteria of toxicity, Hematologic: Febrile neutropenia, Grade 4 neutropenia of greater than (\>) 7 days in duration or requiring Granulocyte- Colony stimulating factor (G-CSF), Grade 4 anemia and Grade 3 thrombocytopenia with bleeding or Grade 4 thrombocytopenia; Non-hematologic: Grade 4 toxicity, Grade 3 pneumonitis, any greater than or equal to (≥) Grade 2 pneumonitis that does not resolve to less than or equal to (≤ ) Grade 1 within 3 days of the initiation of maximal supportive care, Grade 3 toxicity that does not resolve to Grade 1 or baseline within 3 days despite optimal supportive care and any Grade 2 ocular toxicity requiring systemic steroids, or any ≥ Grade 3 ocular toxicity.

The severity of all toxicities were graded using the National Cancer Institute- Common Toxicity Criteria for Adverse Events (NCI-CTCAE) version 5.0. Grade 1: Mild reaction; infusion interruption not indicated; intervention not indicated; Grade 2: Requires therapy or infusion interruption but responds promptly to symptomatic treatment or prophylactic medications indicated for ≤24 hours; Grade 3: Prolonged (i.e., not rapidly responsive to symptomatic medication and/or brief interruption of infusion) or recurrence of symptoms following initial improvement; hospitalization indicated for other clinical sequelae; Grade 4: Life-threatening; pressor or ventilatory support indicated; Grade 5: Death related to AE.

An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of a study intervention, whether or not considered related to the study intervention. An SAE is defined as any untoward medical occurrence that, at any dose: results in death; is life-threatening; requires inpatient hospitalization or prolongation of existing hospitalization; results in persistent disability/incapacity; is a congenital anomaly/birth defect and important medical events may jeopardize the subject or may require medical or surgical intervention/SOC to prevent one of the other outcomes mentioned before. AESIs are defined as events of potential immunologic etiology, including immune related AEs.
