A Study Comparing the Efficiency and Safety of S-CHOP(Cyclophosphamide, Hydroxydaunomycin, Oncovin, and Prednisone) Versus R-CHOP in Untreated CD20(Cluster of Differentiation Antigen 20)-Positive DLBCL Patients

• Status: Unknown status
• Trial end date: 2019-12-01

Summary

The primary objective of the study is to assess the efficiency of SCT400 plus CHOP versus Rituximab plus CHOP in untreated CD20-positive DLBCL Patients.

The secondary objective of the study is to evaluate the safety of SCT400 plus CHOP, as well as the presence of human anti-chimeric antibodies (HACA).

• Phase: Phase 3
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: Sinocelltech Ltd.
• Treatments: Cyclophosphamide; Prednisone; Rituximab

2. Known allergic reactions against any component of CHOP regimen.

3. Previous treatment for DLBCL, including chemotherapy, immunotherapy, partial radiotherapy for lymphoma, monoclonal antibody therapy or surgical treatment (excluding lymph node biopsies and surgical resection for non-lymphoma lesions).

4. History of cytotoxic drugs treatment or anti-CD20 monoclonal antibody treatment for other disease (e.g., rheumatoid arthritis), or prior use of any monoclonal antibody within 3 months.

5. Primary central nervous system(CNS) lymphoma, secondary CNS involvement, grey zone lymphoma (GZL) between burkitt and DLBCL, primary effusion lymphoma, plasmablastic lymphoma, primary cutaneous DLBCL, anaplastic lymphoma kinase(ALK) positive DLBCL or transformed lymphoma.

6. History of other cancer within the past 5 years except cured basal cell skin cancer, squamous cell carcinoma, cutaneous melanoma or carcinoma in situ of the cervix.

7. Patients who have significant cardiac disease, including heart disease of grade Ⅲ of Ⅳ according to the New York Heart Association(NYHA) system, or occurrence of myocardial infarction, unstable arrhythmia, unstable angina or severe hypertension in the past 6 months or peripheral nervous system(PNS) or CNS disease.

8. Previously suffered from progressive multifocal leukoencephalopathy.

9. Having continuous treatment of corticosteroid drugs lasting for more than 10 days:

Prednisone with the dosage over 30mg/day; Other corticosteroid drugs with equal dosage.

10. Participation in another clinical trial in the past 3 months.

11. Recent major surgery within 4 weeks.

12. Use of hemopoietic cytokine in the past 2 weeks, e.g. granulocyte colony stimulating factor(G-CSF).

16. Suspected active or latent tuberculosis.

17. Seropositive for human immunodeficiency virus (HIV) or hepatitis C antibodies. Hepatitis B virus(HBV) positive patient (including positive hepatitis B surface antigen or positive hepatitis B virus core antibody) may participate if his serum HBV DNA level is sufficient low.

18. Other disease or symptom by the investigator's discretion.
