Summary: This is a Phase Ia/Ib, dose escalation and dose expansion study to evaluate the safety, tolerability, PK, pharmacodynamics (PD) and preliminary efficacy of GH2616 Tablet in subjects with advanced solid tumors. It includes two parts: the dose escalation study (Phase Ia) and the dose expansion study (Phase Ib).

Detailed description: Phase Ia: Dose Escalation Study This is a Phase Ia, open-label, multi-center, dose escalation study, aiming to investigate the safety, tolerability, PK, PD and preliminary anti-tumor activity of GH2616 Tablet in subjects with advanced solid tumors. • Dose Escalation Phase This study will consist of 8, sequential, ascending-dose cohorts (A1~ A8) and utilize a "3+3" dose escalation design. Phase Ib: Dose Expansion Study The Phase Ib part is an open-label, multi-center, dose expansion study, aiming to further evaluate the safety, tolerability, PK, PD, and preliminary anti-tumor activity of GH2616 Tablet in subjects with advanced solid tumors harboring TP53 mutation and WGD+ at the RDEs. Phase Ib study will consist of 2 to 3 dose level cohorts (B1 ~ B3) of RDEs identified by the safety, tolerability, PK/PD characteristics, and preliminary efficacy data obtained from Phase Ia study.

Note: The specific tumor types/basket design with specific gene(s) will be determined by the principal Investigator and the Sponsor based on the Phase Ia study results. 4. Survival expectations are ≥ 12 weeks. 5. Eastern Cooperative Oncology Group (ECOG) performance status 0 to 1 (Appendix 1). 6. Subjects with advanced solid tumors have at least one evaluable lesion according to RECIST 1.1 (Appendix 2). 7. Subjects with adequate organ function at the time of screening (requiring no blood transfusion, no use of hematopoietic stimulating factor or human albumin within 14 days prior to screening), specifically defined as: 1. Blood routine: Absolute neutrophil count (ANC) ≥ 1.5×109/L; Platelet count (PLT) ≥100×109/L; Hemoglobin (HGB) ≥ 90 g/L (9 g/dL); 2. Liver function: Serum Total bilirubin (TBIL) ≤ 1.5 Upper limit of normal value (ULN), and serum TBIL≤ 3×ULN in patients with liver metastasis or confirmed Gilbert syndrome. Alanine aminotransferase (ALT) and Aspartate transferase (AST) ≤ 2.5×ULN in subjects without liver metastasis; ALT or AST≤ 5×ULN in subjects with liver metastasis; 3. Renal function: estimated creatinine clearance (CLcr) ≥ 60 mL/min as calculated using Cockcroft-Gault formula (Appendix 3); 4. Coagulation function: Activated Partial thromboplastin Time (APTT) and international normalized ratio (INR) ≤ 1.5×ULN (or within target range if on anticoagulation therapy); 5. Cardiac function: Echocardiography (ECHO) shows left ventricular ejection fraction (LVEF) > 50%. 8. Serum pregnancy test (for female of childbearing potential) negative within 7 days prior to first dosing of study treatment. Male and female subjects of childbearing potential must agree to use effective methods of contraception throughout the study and for 3 months (male) or 6 months (female) after the last dose of the investigational product. A subject is of childbearing potential if, in the opinion of the Investigator, he/she is biologically capable of having children and is sexually active. Exclusion Criteria: - In Phase Ia and Ib studies, subjects will be excluded if they meet any of the following criteria: 1. Has received chemotherapy within 21 days prior to the first administration of GH2616 Tablet or has received radiation therapy, biologic therapy, endocrine therapy, targeted therapy, immunotherapy, or other anti-tumor drug treatments within 28 days prior to the first administration of GH2616 Tablet, or other anti-tumor drugs or treatments within the following interval before the first administration of GH2616 Tablet: Nitrosoureas or mitomycin C within 6 weeks prior to the first administration of the investigational drug. Oral fluoropyrimidines, small molecule targeted therapies, and Chinese herbal medicines with indications for anti-tumor within 14 days prior to the first administration of the investigational drug. Local palliative radiation therapy within 14 days prior to the first administration of the investigational drug. 2. Has received other investigational drugs or treatments not yet approved for marketing within 28 days prior to the first administration. 3. Acute toxic effects of prior anti-tumor therapy have not recovered to clinically significant NCI-CTCAE V5.0 grade ≤ 1 toxicity or baseline specified in the inclusion criteria within 28 days prior to the first administration of GH2616 Tablet (excluding toxicities such as alopecia and fatigue that the Investigator deems to have no safety risk). 4. At rest, the average Corrected QT interval (QTc, Fridericia's correction formula used) obtained by 12-lead Electrocardiograph (ECG) examination is > 450 ms for males or 470 ms for females (confirmed by repeated examinations). A variety of clinically significant arrhythmia, conduction, and resting ECG abnormalities, such as complete left bundle branch block, degree III, degree II, PR interval >250 ms. Various factors that may increase the risk of prolonged QTc or arrhythmia events, such as heart failure, hypokalemia, congenital long QT syndrome, a family history of long QT syndrome in a direct family member or sudden unexplained death before age 40, and use of any medications known to prolong QT intervals. 5. Has evidence of infectious diseases: 1. Active hepatitis B (hepatitis B surface antigen (HbsAg) positive and hepatitis B virus deoxyribonucleic acid (HBV-DNA) > 500 IU/ml or 1000 cps/ml or lower limit of detection at the study site [only if lower limit of detection at the study site is higher than 500 IU/ml or 1000 cps/ml]), antiviral therapy other than interferon is allowed; active hepatitis C (subjects with hepatitis C virus (HCV) antibody positive but hepatitis C virus ribonucleic acid (HCVRNA) < lower limit of detection at the study site are allowed to be enrolled); 2. HIV infected patients (HIV 1/2 antibody positive detected by antigen/antibody test); Considering that HIV infections can be chronically managed, expanding cancer clinical trial eligibility to be more inclusive of patients with HIV infections is justified in many cases, and may accelerate the development of effective therapies in cancer patients with these chronic infections. Therefore, well-controlled HIV patients who have been on established antiretroviral therapy (ART) for at least four weeks and have an HIV viral load less than 400 copies/mL prior to enrollment should be included. Note: patients who are using ART drugs that are prohibited or cautious concomitant medications specified in the protocol (e.g. strong inhibitors or strong inducers of P-gp) could be switched to an alternate effective ART regimen (with minimal drug-drug interaction potential) before study participation or should be excluded from the study if their regimen cannot be altered. 3. Known active syphilis infection. 6. Has symptomatic or active central nervous system (CNS) metastases. Treated or untreated asymptomatic patients with CNS lesions are eligible only if all of the following criteria are met: 1. Presence of measurable lesions outside the CNS as determined by RECIST 1.1. 2. No history of intracranial or spinal hemorrhage. 3. No stereotactic radiation therapy or whole brain radiation therapy or neurosurgical resection within 28 days prior to initiation of study treatment. 4. No continuous use of corticosteroids during CNS disease treatment period. 5. Metastases limited to the cerebellum or supratentorial region (i.e., no metastases to the midbrain, pons, medulla, or spinal cord). 6. No evidence of intermediate progression between completion of CNSdirected therapy (if given) and initiation of study treatment. 7. Concurrent diseases that have not been controlled, such as: 1.
