A Phase 1/2, open label, multi-center study to evaluate the safety, efficacy and tolerability of KY1044 as single agent and in combination with anti-PD-L1 (atezolizumab) in adult patients with selected advanced malignancies, who are ineligible for or there are no available therapies known to confer a clinical benefit for their disease, or they have exhausted all such available options in each indication and therefore will be patients for whom a clinical trial is appropriate.

Inclusion Criteria

Age 18 years (20 years in Taiwan)
Histologically documented advanced/metastatic malignancies
Phase 1 and Phase 2 participants with advanced/metastatic malignancies who have measurable disease (non-measurable disease is allowed only in Phase 1) as determined by RECIST 1.1 will be eligible if, according to the National Comprehensive Cancer Network (NCCN) guidelines, there are no available therapies known to confer a clinical benefit for their disease, or they have exhausted all such available options. Additionally, the following specific tumor indications will be enrolled
Phase 1: Participants with advanced/metastatic malignancies, and preferred indications (non-small cell lung cancer (NSCLC), head and neck squamous cell carcinoma (HNSCC), hepatocellular carcinoma (HCC), melanoma, cervical, esophageal, gastric, renal, pancreatic, and triple negative breast cancer)
Phase 2 KY1044 single agent: Participants with advanced/metastatic malignancies in indications in which signs of anti-tumor activity (Complete Response (CR), Partial Response (PR) or durable stable disease (SD) with tumor shrinkage that does not qualify for PR) were seen during the dose escalation of KY1044 as single agent
Phase 2 KY1044 in combination with atezolizumab: Participants with advanced/metastatic malignancies in the selected indications below, and/or indications which have shown promising activity in Phase 1
NSCLC (anti-PD-(L)1 therapy nave and pre-treated)
Gastric (anti-PD-(L)1 therapy nave and pre-treated)
HNSCC (anti-PD-(L)1 therapy nave and pre-treated)
Esophageal (anti-PD-(L)1 therapy nave and pre-treated)
Cervical (anti-PD-(L)1 therapy nave and pre-treated)
Indications, in which signs of anti-tumor activity has been observed in Phase 1 with KY1044 in combination with atezolizumab
Prior therapy with anti-PD-(L)1 inhibitors is allowed provided any toxicity attributed to prior anti-PD-(L)1-directed therapy did not lead to discontinuation of therapy
Eastern Cooperative Oncology Group (ECOG) Performance Status 0-1
Life expectancy longer than 12 weeks
Must have a site of disease amenable to biopsy, and be a candidate for tumor biopsy according to the treating institution's guidelines. Participants must be willing to undergo a new tumor biopsy at screening, and during therapy on the study

Exclusion Criteria

Presence of symptomatic central nervous system (CNS) metastases, or CNS metastases that require local CNS-directed therapy, or increasing doses of corticosteroids within the prior 2 weeks of first dose of study treatment
History of severe hypersensitivity reactions to other monoclonal antibodies and/or their excipients
Known presence of neutralizing anti-atezolizumab antibodies (for patients previously treated with atezolizumab)
Having out of range laboratory values: creatinine, bilirubin, alanine aminotransferase (ALT), aspartate aminotransferase (AST), absolute neutrophil count (ANC), platelet count, hemoglobin
Impaired cardiac function or clinically significant cardiac disease
Known human immunodeficiency virus (HIV), active hepatitis B virus (HBV) or active hepatitis C virus (HCV) infection
Malignant disease, other than that being treated in this study
Any medical condition that would, in the Investigator's judgment, prevent participation in the clinical study due to safety concerns, compliance with clinical study procedures or interpretation of study results
Active autoimmune disease or a documented history of autoimmune disease
Participants previously exposed to anti-PD-(L)1 treatment who are not adequately treated for skin rash or had no replacement therapy for endocrinopathies should be excluded
Participants with a history of drug-induced pneumonitis or current pneumonitis
Systemic steroid therapy or any immunosuppressive therapy. Topical, inhaled, nasal, and ophthalmic steroids are not prohibited
Use of live attenuated vaccines against infectious diseases within 4 weeks of the first dose of study treatment. SARS-CoV-2 vaccines authorized for use by the competent local regulatory health authorities for active immunization to prevent COVID 19 are allowed (unless the vaccine is live or live attenuated) and must be given in accordance with the prevailing immunization guidelines
Anti-CTLA4, anti-PD-(L)1 treatment within 4 weeks of the first dose of study treatment
Pre-treatment with anti-CTLA4 antibodies in combination with any other antibody or drug specifically targeting T-cell co-stimulation or checkpoint pathway
Presence of Common Terminology Criteria for Adverse Events version 5 (CTCAE v5) Grade 2 toxicity (except alopecia, peripheral neuropathy and ototoxicity, which are excluded if CTCAE v5 Grade 3) due to prior cancer therapy
Radiotherapy within 2 weeks of the first dose of study treatment, except for palliative radiotherapy to a limited field, such as for the treatment of bone pain or a focally painful tumor mass. To allow evaluation for response to treatment, participants enrolled in the Phase 2 part must have remaining measurable disease that has not been irradiated
Pregnant or lactating women
