Criteria

Inclusion Criteria:

Written informed consent must be obtained prior to any procedures that are related to this study.
Patients (male or female) ≥ 18 years of age
Eastern Cooperative Oncology Group (ECOG) performance status≤1
Presence of at least one measurable lesion according to the Response Evaluation Criteria in Solid Tumors (RECIST) v1.1.
Phase I study part: Histologically or cytologically confirmed metastatic or locally advanced solid tumors, for which no standard therapy exits or the standard therapy has failed.

Phase II study part: 1. Histologically or cytologically confirmed metastatic or locally advanced solid tumors of the selected indications. 2. Positive FGF19 in IHC test results of tumor tissues in pre-screening.

Exclusion criteria:

Prior therapies within the following time frames prior to the first dose of study treatment:

Last dose of conventional cytotoxic chemotherapy: ≤4 weeks ((≤ 6 weeks for nitrosoureas and mitomycin-C);
Drugs with anti-tumor activity (e.g., antibodies): ≤4 weeks
Non-cytotoxic small molecule therapeutics (e.g., sorafenib): ≤5 half-lives or ≤2 weeks (whichever is longer)
Previous wide field radiotherapy (including therapeutic radioisotopes such as strontium 89) ≤ 4 weeks and limited field radiation for palliation ≤ 2 weeks (including particle implantation such as I125);
Participation in a prior investigational study: ≤ 4 weeks;
Drugs with immunomodulatory activity (such as thymosin, interferon, interleukin, etc.) ≤ 6 weeks.
Major surgery within 4 weeks of receiving the first dose of study treatment (mediastinoscopy, insertion of a central venous access device and insertion of a feeding tube are not considered major surgery).
Subject having out of range laboratory values including hematology, chemistry and coagulation indicators. See Section 5.3 for specific indicators.
Use of hematopoietic colony-stimulating growth factors (e.g. G-CSF, GM-CSF, M CSF), blood transfusion products (e.g., whole blood, plasma, apheresis platelets, etc.), thrombopoietin mimetics or erythroid stimulating agents ≤ 2 weeks prior to start of study treatment. If erythroid stimulating agents were initiated more than 2 weeks prior to the first dose of study treatment and the patient is on a stable dose, they can be maintained.
Malignant disease, other than that being treated in this study. Exceptions to this exclusion include the following: malignancies that were treated curatively and have not recurred within 5 years prior to study entry; completely resected basal cell and squamous cell skin cancers and completely resected carcinoma in situ of any type.
Symptomatic CNS metastases which are neurologically unstable, or CNS metastases requiring local CNS directed therapy (such as radiotherapy or surgery), or increasing doses of corticosteroids within 2 weeks of first dose of study treatment.
Serous effusion with clinically significant symptoms (such as shortness of breath, abdominal distention, etc.).

Major acute or chronic infections, including:

Positive human immunodeficiency virus (HIV) antibody screening or known acquired immunodeficiency syndrome (AIDS);
Active hepatitis B virus (HBV) or hepatitis C virus (HCV) infection: positive HBV-DNA copies (>2000 IU/mL) and/or other activity indicators; positive HCV antibody and HCV-RNA test result;
active TB (such as exposure history or positive TB test; AND clinical symptoms, physical or imaging manifestations);
Ongoing antibiotic treatment of serious acute infections.
Previous treatment with a selective FGF19-FGFR4 targeted therapy and/or pan-FGFR inhibitor.
Patients receiving treatment with cytochrome P450 (CYP)1A2, CYP2C9 and CYP3A4/5 substrates with a narrow therapeutic index (NTI) that cannot be discontinued for the duration of the study.
Patients receiving known BSEP efflux transporter inhibitors that cannot be discontinued 3 days prior to the start of study treatment and during the course of the study.
Current evidence of calcium-phosphate homeostasis impairment. See Section 5.3 for specific indicators.
Impairment of gastrointestinal (GI) function or GI disease that may significantly alter the absorption of oral EVER4010001 (e.g., ulcerative diseases, uncontrolled nausea, vomiting, small bowel resection).
Ongoing active diarrhea requiring medications (e.g. bile acid sequestrant (BAS), loperamide).
Irritable bowel syndrome with signs/symptoms or requires medications.
Any previous specific target T cell co-stimulation or immune checkpoint pathway treatment, including but not limited to PD-1 inhibitors, PD-L1 / 2 inhibitors or other targeted T cell drugs.
Use of systemic chronic steroid therapy (≥ 10mg/day prednisone or equivalent) or any immunosuppressive therapy two weeks prior to start of study treatment. Topical, inhaled, nasal and ophthalmic steroids are allowed.
Use of any live vaccines against infectious diseases within 4 weeks of initiation of study treatment (except inactivated seasonal influenza vaccines).
Active known or suspected autoimmune disease. Patients with vitiligo, residual hypothyroidism only requiring hormone replacement, or psoriasis not requiring systemic treatment can be included.
History of severe hypersensitivity reactions to any ingredient of study treatment and other monoclonal antibodies (mAbs) and/or their excipients.

Impaired cardiac function or clinically significant cardiac disease, including any of the following:

-Clinically significant or uncontrolled heart disease such as congestive heart failure requiring treatment (New York Heart Association Grade ≥ 2), uncontrolled hypertension (defined by Systolic Blood Pressure > 160 mmHg/ Diastolic Blood Pressure > 100mmHg (average of three consecutive readings) at rest despite medical treatment, 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 screening.

History of liver or other organ transplantation.
History of interstitial lung disease or pneumonia requiring oral or intravenous steroids.
Pregnant or nursing (lactating) women, where pregnancy is defined as the state of a female after conception and until the termination of gestation, confirmed by a positive human chorionic gonadotropin (hCG) laboratory test.
Women of child-bearing potential, defined as all women physiologically capable of becoming pregnant, unless they are using highly effective methods of contraception during dosing with study treatment and for the following duration after discontinuation of study treatment: See Section 5.3 for specific contraception methods.
Sexually active males unless they use a condom during intercourse while receiving study treatment and for the following period after the last dose of study treatment, and should not father a child in this period.
Any medical condition that would, in the investigator's judgment, prevent the patient's participation in the clinical study due to safety concerns or compliance with clinical study procedures. Any severe, acute, or chronic medical or psychiatric condition or laboratory abnormality that may increase the risk associated with study participation or study treatment administration or that may interfere with the interpretation of study results and, in the judgment of the investigator, would make the patient inappropriate for the study.
