Inclusion Criteria: 1. Male or female, age ≥ 18 years 2. Histologically/cytologically confirmed, locally advanced unresectable or metastatic solid tumors that are refractory to or intolerant of existing standard therapy, for which no effective standard therapy that confers clinical benefit is available 3. Availability of archival tissue specimens for EpCAM immunohistochemistry (IHC) staining. Tumor tissues acceptable include: \- Tumor tissue sample collected at the time of initial diagnosis \- The most recent available recurrent/metastatic tumor biopsy tissue if available (a pre-treatment biopsy is encouraged if the biopsy site is safely accessible) Note: this criterion is fulfilled if there is a qualified tumor sample (tumor cells were presented in the tumor biopsy tissue), and the tumor tissue slides can be obtained for IHC staining. It is not violated even if the staining result from biopsy obtained after the screening visit reveals that the slides contain no identifiable tumor cells. 4. Has at least one measurable lesion according to Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 5. Eastern Cooperative Oncology Group (ECOG) performance score ≤ 2 6. Subject's life expectancy of at least 12 weeks 7.

A female subject with childbearing potential should be confirmed of not being pregnant or not lactating at the screening and during the study 9. Willingness and ability to comply with protocol-stated requirements, instructions, and restrictions in the investigator's judgement 10. Is able to understand the nature of this study and accepts to enter the study by signing written informed consent Exclusion Criteria: 1. Received any localized cancer therapeutic modalities (e.g., surgery on target lesions, radiotherapy) within 4 weeks prior to initial dosing (except the palliative radiotherapy performed on non-target local lesions), or have any unrecovered surgical wound (except the wound from the biopsy at screening) 2. Received anti-tumor therapies such as chemotherapy, small molecular targeted therapy, hormone therapy, biological product therapy (mAbs, bispecific antibody, and ADC), or other anti-cancer agents within 2 weeks or 5 half-lives (whichever is shorter) before the first AM-928 dosing; received immunotherapy within 4 weeks or 5 half-lives (whichever is shorter) before the first AM-928 dosing. 3. Carries history of primary malignancy other than the entry diagnosis that could affect compliance with the protocol or interpretation of results within 3 years prior to the Screening Visit, except curatively treated non-melanoma skin cancer, cervical carcinoma in situ, or superficial bladder tumors 4. Received immunosuppressive medication(s) (including, but not limited to, steroids, cyclophosphamide, azathioprine, methotrexate, thalidomide, tumor necrosis factor-ɑ antagonists, and calcineurin inhibitors) within 2 weeks (for those half-life ≤ 72 hours) or 4 weeks (for those half-life \> 72 hours) prior to study dosing and during the study period, with the following caveats: \- For steroids, ≤10 mg of prednisone per day or equivalent is allowed * Topical, ocular, intra-articular, intranasal, and inhaled corticosteroids is allowed. For a subject under long-term treatment of a concurrent disease/status, the dose should be stable (i.e., no change or decreasing dose) within 3 months prior to C1D1 * The use of inhaled corticosteroids is allowed if they are on a stable dose (i.e., no change or decreasing dose within 3 months prior to C1D1) * The use of oral mineralocorticoids is allowed * Physiologic doses of corticosteroids for adrenal insufficiency or supportive care for a subject's advanced tumor may be allowed at the investigator's discretion 5. Subject with significant cardiopulmonary abnormalities as defined by: * Poorly controlled hypertension (systolic blood pressure \> 150 mm-Hg and/or diastolic blood pressure \> 100 mm-Hg on anti-hypersensitive medications) * Left ventricular ejection fraction (LVEF) \< 50% at screening * History of symptomatic congestive heart failure \> class 2 per New York Heart Association (NYHA) classification * History of myocarditis * Myocardial ischemia/infarction or unstable angina within 6 months of study enrollment * Uncontrolled serious cardiac arrhythmias * Corrected QT interval \> 470 ms demonstrated by at least 2 ECGs \> 30 minutes apart * Evidence of active pneumonitis (including drug-induced), organizing pneumonia (i.e., bronchiolitis obliterans, cryptogenic organizing pneumonia, etc.), or history of idiopathic pulmonary fibrosis. History of radiation pneumonitis in the radiation field (fibrosis) is permitted. * History of 2nd or 3rd-degree atrioventricular conduction defects 6. History of thromboembolic or cerebrovascular events within the last 6 months at screening, including transient ischemic attack, cerebrovascular accident, or deep vein thrombosis 7. Prior treatment with any EpCAM-targeted anti-cancer therapies 8. Subjects with the following infections: \- History of active pulmonary tuberculosis infection ≤ 48 weeks prior to C1D1, regardless of treatment * Any major episode of infection requiring treatment with systemic antibiotics or hospitalization within 2 weeks prior to C1D1 * Known human immunodeficiency virus (HIV) history * Presence of hepatitis B surface antigen (HBsAg) with HBV viral load \> 2000 IU/mL (HBsAg-positive subjects with HBV viral load ≤ 2000 IU/mL are eligible. These subjects should continue to receive antiviral treatment during the study treatment and follow local HBV antiviral treatment standards after the study treatment during the study) * HCV RNA positive (subjects with a history of HCV infection are eligible if their HCV viral load cannot be detected at screening; curative antiviral therapy should have been completed at least 4 weeks before C1D1) 9. Administration of a live, attenuated vaccine within 4 weeks before C1D1 or anticipation that such a live, attenuated vaccine will be required during the study 10. Received any investigational product within 4 weeks before C1D1 11. History of severe allergic, anaphylactic, or other hypersensitivity reactions to humanized antibodies 12. Known hypersensitivity to any of the components of AM-928 13.

Prior allogeneic stem cell, solid organ, or bone marrow transplantation 17. Subject with any underlying medical, mental, or psychological conditions that would impair the treatment compliance, contraindicate the use of the investigational product, or that may render the subject at high risk from treatment complications, in the opinion of the investigator, would not permit to participate in the study 18. All male subjects and female subjects with childbearing potential (between puberty and 1 year after menopause) should use at least one of the appropriate contraception methods shown below from signing ICF to at least 4 months or 5 half-lives (if data available), whichever is longer, after stopping study treatment. 1. Total abstinence (when this is in line with the preferred and usual lifestyle of the subject). Periodic abstinence (e.g., calendar, ovulation, symptothermal, post-ovulation methods) and withdrawal are not acceptable methods of contraception. 2. Female sterilization (have had surgical bilateral oophorectomy with or without hysterectomy), total hysterectomy, or tubal ligation at least 6 weeks before taking study treatment. In the case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow up hormone level assessment. 3. Male sterilization (at least 6 months prior to screening). For female subjects on the study, the vasectomized male partner should be the sole partner for that subject. 4. Combination of any two of the following listed methods: (d.1+d.2 or d.1+d.3, or d.2+d.3): d.1. Use oral, injected, or implanted hormonal methods of contraception or other forms of hormonal contraception that have comparable efficacy (failure rate \<1%), for example, hormone vaginal ring or transdermal hormone contraception. d.2. Placement of an intrauterine device (IUD) or intrauterine system (IUS). d.3. Barrier methods of contraception: Condom or Occlusive cap (diaphragm or cervical/vault caps) with spermicidal foam/gel/film/cream/vaginal suppository.
