Summary

This is a single arm, open label, national multicenter clinical study included patients with marginal zone lymphoma patients (MZL) , aim is to evaluate the efficacy and safety of first-line treatment with Linperlisib combined with obinutuzumab in patients with marginal zone lymphoma (MZL).

Biochemical examination:

1. TBIL\<1.5 x upper limit of normal range (ULN);
2. Glutamate alanine aminotransferase (ALT) and Glutamate aspartate aminotransferase (AST) ≤ 2.5 × ULN;
3. Serum creatinine (Cr) ≤ 1.25 × ULN or Endogenous creatinine clearance rate ≥ 60 mL/min (Cockcroft Gault formula);

Coagulation function:

1. International Normalized Ratio (INR) ≤ 1.5 × ULN;
2. Activated partial thromboplastin time (APTT) ≤ 1.5 × ULN; 9. Women who have the possibility of pregnancy must undergo a serum pregnancy test within 7 days before the first use of the test drug, and the result must be negative. They must also be willing to use effective contraception methods during the trial period and within 1 year after the last administration of the test drug. For male participants whose partners are women of childbearing age, surgical sterilization should be performed, or they should agree to use efficient contraception methods during the trial period and one year after the last administration of the trial drug; 10. The subjects voluntarily joined this study, signed an informed consent form, had good compliance, and cooperated with follow-up

Exclusion Criteria:

* 1\. Patients who have received any targeted PI3K therapy before enrollment; 2. History of other primary invasive malignant tumors that have not been relieved or have not been relieved for more than 3 years; 3. Patients with involvement of the central nervous system (meninges or brain parenchyma); 4. Individuals who are known to have allergies to any of the drugs in the study; 5. Participated in clinical trials of other drugs within 4 weeks prior to the start of the study; 6. Pregnant or lactating women; 7. Individuals with active infections, except for those with tumor related B symptoms and fever; 8. Combined diseases and medical history:

  1. There are multiple factors that can affect oral medication, such as inability to swallow, chronic diarrhea, and intestinal obstruction;
  2. Individuals with a history of abuse of psychotropic drugs who are unable to quit or have mental disorders;
  3. Subjects with any severe and/or uncontrolled illnesses, including:

     1. Poor blood pressure control (systolic blood pressure ≥ 150mmHg or diastolic blood pressure ≥ 100 mmHg);
     2. Suffering from ≥ grade 2 myocardial ischemia or myocardial infarction, arrhythmia \[including QTc ≥ 450ms (male), QTc ≥ 470ms (female)\], and ≥ grade 2 congestive heart failure \[New York Heart Association (NYHA) classification\];
     3. Active interstitial pneumonia or other chronic lung diseases leading to severe impairment of lung function, defined as FEV1 and DLCOc\<60% of normal predicted values; History of interstitial pneumonia caused by COVID-19.
     4. Liver abnormalities:
     5. Decompensated cirrhosis (Child Pugh liver function rating B or C)
     6. Known history of liver disease with clinical significance. Including viral hepatitis, known carriers of hepatitis B virus (HBV) must exclude active HBV infection, i.e. HBV DNA positive (\>2500 copies/mL or \>500IU/mL, and greater than the upper limit of normal); Known to be infected with hepatitis C virus (HCV) and HCV RNA positive (\>1 × 103 copies/mL). Note: hepatitis B HBsAg positive subjects who meet the inclusion conditions, whether their HBV DNA is measurable or not, need to continue antiviral treatment (nucleoside analogues are recommended) and regularly monitor HBV DNA; For subjects with positive HBcAb but negative HBsAg in hepatitis B, HBV DNA should be monitored regularly and preventive antiviral treatment should be recommended; HCV RNA should be regularly monitored in subjects with hepatitis C.
     7. Patients with renal failure requiring hemodialysis or peritoneal dialysis;
     8. Subjects with uncontrolled pleural effusion, pericardial effusion, or ascites that require repeated drainage;
     9. Poor control of diabetes (FBG\>10mmol/L);
     10. Urine routine shows urinary protein ≥++and confirms 24-hour urinary protein quantification\>1.0g; 9. History of immunodeficiency, including HIV testing positive, or other acquired or congenital immunodeficiency diseases, or a history of organ transplantation; 10.According to the researchers assessment, there are accompanying diseases that pose a serious threat to patient safety or affect the completion of the study.
