Patients eligible for inclusion in this study must meet all of the following criteria:
1. Written informed consent must be obtained prior to any procedures
2. Age =18 years (=20 years in Taiwan)
3. Histologically documented advanced/metastatic malignancies
4. Phase 1 and Phase 2 patients 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 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:
a.Phase 1 (including enrichment part):
Patients with advanced/metastatic malignancies, and preferred indications as identified in Section 3.1 (NSCLC, HNSCC, HCC, melanoma, cervical, esophageal, gastric, renal, pancreatic, and triple negative BC)
b.Phase 2 KY1044 single agent:
Patients with advanced/metastatic malignancies in indications in which signs of anti tumor activity (CR, PR or durable SD with tumor shrinkage that does not qualify for PR) were seen during the dose escalation of KY1044 as single agent.
c.Phase 2 KY1044 in combination with atezolizumab:
Patients with advanced/metastatic malignancies in the below selected indications, and/or indications which have shown promising activity in Phase 1:
•NSCLC (anti PD (L)1 therapy naïve and pre treated)
•Gastric (anti PD (L)1 therapy naïve and pre treated)
•HNSCC (anti PD (L)1 therapy naïve and pre treated)
•Esophageal (anti PD (L)1 therapy naïve and pre treated)
•Cervical (anti PD (L)1 therapy naïve and pre treated)
Indications, in which signs of anti tumor activity has been observed in Phase 1 with KY1044 in combination with atezolizumab
5. 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
6. Eastern Cooperative Oncology Group (ECOG) Performance Status 0-1
7. Life expectancy longer than 12 weeks
8. Must have a site of disease amenable to biopsy, and be a candidate for tumor biopsy according to the treating institution’s guidelines. Patient must be willing to undergo a new tumor biopsy at screening, and during therapy on the study
9. Women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation and for at least 5 months after discontinuing study treatment, or longer if the half-life of KY1044 is observed to exceed that of atezolizumab
10. For the duration of study participation and for at least 5 months after discontinuing study treatment, or longer if the half-life of KY1044 is observed to exceed that of atezolizumab, sexually active males must use barrier contraception (i.e., condoms).
Are the trial subjects under 18? no
Number of subjects for this age range:
F.1.2 Adults (18-64 years) yes
F.1.2.1 Number of subjects for this age range 330

F.1.3.1 Number of subjects for this age range 82
Patients eligible for this study must not meet any of the following criteria:
1. Presence of symptomatic 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. Patients with treated brain metastasis unless neurologically stable (for 4 weeks posttreatment and prior to study enrolment) and off of steroids for at least 2 weeks before the first dose of study treatment
2. History of severe hypersensitivity reactions to other mAbs and/or their excipients

5. Impaired cardiac function or clinically significant cardiac disease,
including any of the following:
- Clinically significant and/or uncontrolled heart disease such as
congestive heart failure requiring treatment, uncontrolled hypertension
or clinically significant arrhythmia
- QTcF >470 msec on screening ECG or congenital long QT syndrome
- Acute myocardial infarction or unstable angina pectoris <3 months prior to first dose of study treatment
6. Known human immunodeficiency virus (HIV), active hepatitis B virus (HBV) or active hepatitis C virus (HCV) infection.
7. Malignant disease, other than that being treated in this study.
8. Any medical condition that would, in the Investigator's judgment, prevent the patient's participation in the clinical study due to safety concerns, compliance with clinical study procedures or interpretation of study results
9. Active autoimmune disease or a documented history of autoimmune disease
10. Patients 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
11. Patients with a history of drug-induced pneumonitis or current pneumonitis
12. Systemic steroid therapy or any immunosuppressive therapy. Topical, inhaled, nasal, and ophthalmic steroids are not prohibited
13. Herbal preparations/medications (including, but not limited to: St.
John's Wort, kava, ephedra (ma huang), gingko biloba, dehydroepiandrosterone, yohimbe, saw palmetto, and ginseng) are prohibited from the time that patients enter the screening period (at least 7 days prior to first dose of study treatment) until the last dose of study treatment (3 weeks for St John's Wort)
14. Warfarin and other types of long acting anticoagulants is prohibited within 4 weeks of the first dose of study treatment and patients requiring anticoagulant treatment should switch to low molecular weight heparin
15. Use of life attenuated vaccines against infectious diseases within 4 weeks of the first dose of study treatment
16. Systemic anti-cancer therapy within 2 weeks of the first dose of study treatment. For cytotoxic agents that have major delayed toxicity, 4 weeks is indicated as washout period
17. Major surgery within 2 weeks of the first dose of study treatment
