A Study to Investigate Safety and Tolerability of SH3765 Tablet in Patients With Advanced Malignant Tumor

NCT05015309 | Unknown Phase 1

• 1 other identifier: SHC039-I-01
• Study Type: interventional
• Target: 40
• Locations: 1 country
• Sites: 1

Brief Summary

The primary objective is to determine the safety and tolerability of SH3765 in subjects with advanced malignant tumor by determining the maximum tolerated dose (MTD) and recommended Phase 2 dose (RP2D). The second objective is to evaluate the PK profile and preliminary efficacy of SH3765 in subjects with advanced malignant tumor.

Conditions

Advanced Malignant Tumor

Outcome Measures

Primary Outcomes (2)

• Dose-limiting toxicity (DLT)

  DLT is defined as an adverse event that meets protocol defined DLT criteria occurring from the first dose to the end of cycle 1 of multiple doses, except those unequivocally due to the underlying malignancy or an extraneous cause.

  Within the first 28 days of consecutive treatment

• Maximum tolerated dose (MTD)

  MTD was defined as the highest dose at which DLT occurred in less than one-third of subjects during the DLT observation period.

  Within the first 28 days of consecutive treatment

Secondary Outcomes (10)

• Cmax

  4 weeks

• Tmax

  4 weeks

• T1/2

  4 weeks

• Area Under the Curve (AUC)

  4 weeks

• Mean Residence Time (MRT)

Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• Age ≥ 18 years;
• Patients must have a histologically or cytologically confirmed diagnosis of relapsed or refractory solid tumors or non-Hodgkin lymphomas (NHLs), with the following criteria specific to each tumor type:
• For solid tumors: Patients must have advanced triple-negative breast cancer (TNBC), non-small cell lung cancer (NSCLC), adenoid cystic carcinoma (ACC), prostate cancer (PC), or head and neck squamous cell carcinoma (HNSCC). The malignancy must be relapsed or refractory after at least 1 prior line of anti-tumor therapy, and for which there are no available standard of care therapy or therapies known to provide clinical benefit; For NHLs: Patients must have mantle cell lymphoma (MCL), or non-germinal center B-cell-like (non-GCB) subtypes of diffuse large B-cell lymphoma (DLBCL) (both de novo and transformed non-GCB DLBCL are allowed). The malignancy must be relapsed or refractory after at least 2 prior lines of anti-tumor therapy, and for which there are no available standard of care therapy or therapies known to provide clinical benefit. The patients who require urgent cytoreductive therapy will be excluded, unless the patient has no remaining treatment choice with potential benefits.
• Patients must provide archival tumor tissue, if available, from the most recent biopsy, or are able to undergo a tumor biopsy during screening;
• At least one evaluable or measurable tumor lesion;
• Eastern Cooperative Oncology Group (ECOG) Performance Status of 0 to 1;
• Life expectancy ≥3 months;
• Adequate hematological and biological function, confirmed by the following laboratory values (Have not received blood transfusion or hematopoietic stimulating factor treatment within 14 days):APTT ≤1.0×ULN; Total bilirubin (TBIL) ≤1.5×ULN if no demonstrable liver lesion(s) (primary or metastases) or ≤3×ULN in the presence of documented Gilbert's Syndrome (unconjugated hyperbilirubinemia) or liver lesion(s); Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤2.5×ULN if no demonstrable liver lesion(s) (primary or metastases) or ≤5×ULN in the presence of liver lesion(s); Creatinine clearance ≥50mL/min (Calculated according to Cockcroft-Gault formula); Left ventricular ejection fraction (LVEF) ≥50%; QT interval corrected using Fridericia's method (QTcF)\<470 msec; For advanced solid tumors patients: ANC ≥1.5×109/L, PLT ≥100×109/L, Hemoglobin (Hb) ≥90 g/L; For advanced non-Hodgkin lymphoma patients: ANC ≥ 1.0×109/L, PLT ≥ 80×109/L, Hemoglobin (Hb) ≥80 g/L;
• Women of child bearing potential must agree to use a reliable form of contraception during the study treatment period and for at least 180 days following the last dose of study drug, and 3 days before treatment the pregnancy tests are negative. Men must agree to the use of male contraception during the study treatment period and for at least 180 days after the last dose of study drug;
• Not using any other investigational drugs within 30 days before the study drugs administration;
• Be informed of the trial before the start of the trial, and voluntarily sign the name and date on the informed consent form.

You may not qualify if:

• Prior treatment with PRMT5 inhibitors;
• Anticancer treatment including radiation therapy, chemotherapy, hormonal therapy, molecular targeted therapy, or immunotherapy within 3 weeks before the first dose of SH3765 (use of mitomycin or nitrosoureas within 6 weeks before the first dose; use of oral fluorouracil, such as tegafur and capecitabine, within 2 weeks before the first dose; use herbal medicine with anti-tumor indications within 2 weeks before the first dose);
• Evidence of central nervous system (CNS) metastases;
• Evidence of any severe or uncontrolled systemic diseases, including uncontrolled hypertension, active bleeding diatheses, uncontrolled pleural effusion and ascites, uncontrolled diabetes, non-infectious pneumonia, or any other severe cardiovascular, respiratory, nervous and mental diseases;

• Active infection with hepatitis B virus (HBV), hepatitis C virus (HCV) or human immunodeficiency virus (HIV). Patients with HBsAg positive but HBV-DNA negative, or with HCV antibody positive but HCV-RNA negative, or with HIV antibody positive but HIV-RNA negative and CD4+ T cell count normal will be inclusive;
• Patients who received systemic glucocorticoids (prednisone \>10 mg/ day or equivalent dose of the same drug) or other immunosuppressive therapy within 14 days before the first administration; except for topical, ocular, intra-articular, intranasal, and inhaled glucocorticoids; short-term use of glucocorticoids for prophylactic treatment (e.g., prevention of contrast agent allergy);
