Brief Summary

This study was conducted to evaluate the complete response rate of avelumab in patients with NK / T-cell lymphoma besides relapsed or refractory stage lymphoma.

Detailed Description

Extranodal natural killer/T-cell lymphoma (ENKTL) generally has poorer prognosis than other lymphomas because the majority of patients are present as advanced disease and show poor response to treatment.

In particular, treatment of relapsed or refractory stage ENKTL is very poor and there is no standard treatment.

ENKTL is entirely infected with Epstein-Barr virus (EBV) and the prevalence of this disease is closely related to EBV.

Therefore, the biological properties of ENKTL may be affected by EBV-related protein and LMP1 may induce activation of molecules in various sub-channels, such as PI3K/Akt and NF-kB, and affect the aggressiveness of lymphoma.

As an increase in PDL1 has been reported recently among the major roles of LMP1, the role of Immuno-oncology drug targeting PDL1 among ENKTL is expected.

Therefore, Avelumab that inhibits PDL1 may effectively treat NK/T-cell lymphoma besides relapsed or refractory stage lymphoma.

Eligibility Criteria

Inclusion Criteria

1. Historologically diagnosed ENKTL: The standards of WHO Classification 2016 for diagnosis of ENKTL satisfied.

2. Became relapsed or refractory after at least one kind of treatment after initial diagnosis.

3. If there is at least one measurable lesion.

4. In case full-body activity (ECOG PS) is levels 0-2.

5. In case of written consent to participation in clinical study: Must sign the subject consent form that states the sampling done at the time of diagnosis or relapse (must provide sample): 10 4um (at least 5) and biomarker (3~5 ml peripheral blood drawn during screening period, must provide sample) and that the subject has comprehended the purpose and the necessary procedures of clinical study with intention to participate in the clinical study (or signed by the subject's representative).

6. If older than 19 years of age.

7. If the following hematological results are satisfied:

• Absolute neutrophil count is 1500/mm3 or greater regardless of growth factor supply.
• Platelet count is 100,000/mm3 or greater regardless of blood supply. (However, in cases of disease involvement, for example, platelet decrease due to bone marrow involvement or spleen enlargement, patients with a platelet count greater than 50000/mm3 may participate in this study.)
• Hemoglobin is 9.0 g/dL or greater.

8. If the following biochemical results are satisfied:

• Alanine transaminase (ALT) and Aspartate transaminase (AST) ≤ 2.5 x upper limit (ULN): If liver blood enzyme count is increasing due to a disease, such as the lymphoma's hepatic intrusion, may register up to ≤ 5 x ULN at investigator's discretion.
• If bilirubin is increasing due to the Gilbert Syndrome, total bilirubin ≤ 1.5 x ULN unless non-hepatic.
• Serum creatinine ≤ 2 x ULN or glomerular filtration rate (Cockroft Gault) ≥ 30 mL/min/1.73m2.

9. Highly efficient birth control that meets the local regulations must be adopted for birth control of subjects that participate in the clinical study during or after the clinical study for women in fertility or sexually active men (in case of women in fertility, effective birth control must be used during the administration of study drug and for 1 month after that and men must use it during the administration of studyt drug and for 3 months after that).

10. Women in fertility must show negative results at platelet (beta-chorionic gonadotropin) or pregnancy test by urine at screening.

Exclusion Criteria

1. If there is history of carcinomatous meningitis, symptomatic leptomeningeal diseases or evidence of secondary intrusion on the central nervous system based on CT or MRI scanning.

2. In case there are other carcinomas besides the target disease or in case of anamnesis of other malicious tumers during the past 3 years from the start of clinical study: Excluding basal cell carcinoma and cervical intraepithelial neoplasia that are appropriately treated.

3. If any toxicity from the previous chemotherapy has not recovered to grade 1 or lower at the time of screening; however hair loss and bone marrow inhibition are excluded and peripheral polyneuropathy may be registered at researcher's discretion if there is no risk of safety at Grade≤ 2.

4. In case of major operation within 4 weeks from registration for the clinical study or failure to recover from a major complication of such operation.

5. If using immunosuppressant drugs at the time of registration for the clinical study: Excluding local steroid injections such as nasal or inhalated steroid, steroid ointment, and injections in articular cavities. In case of full-body steroid administration, 10 mg or smaller prednisolonum a day is permissible (If adrenal insufficiency is necessary to maintain a dose of prednisolone 10 mg or more, it is acceptable according to the investigator's judgment) and steroid injections used for pre-treatment before CT or other examination are also permitted.

6.

In case of known history of human immunodeficiency virus (HIV), active type C hepatitis virus, or active type B hepatitis virus (However, in the case of healthy carriers who did not require asymptomatic treatment, if the antiviral drug can be taken, it can be registered by the judgment of the investigator. In this case, the HBV DNA test should be monitored periodically through division of gastroenterology) or uncontrolled active full-body infection that requires intravenous (IV) antibiotics.

9. In case of life-threatening diseases, medical conditions, or respiratory failure that may threaten the safety of subjects or put the results of clinical study in danger.

10. In case of homogeneous hematopoietic stem cell transplant.

13. If candidate is pregnant or breast-feeding at the time of screening.

14. In case of a major operation or live attenuated vaccine within 4 weeks of registration for the clinical study.

15. In case of the following hepatic diseases:

• Chronic hepatitis or liver cirrhosis related to type B or type C hepatitis.
• Positive reaction for surface antigen of type B hepatitis without symptoms. (However, in the case of healthy carriers who did not require asymptomatic treatment, if the antiviral drug can be taken, it can be registered by the judgment of the investigator. In this case, the HBV DNA test should be monitored periodically through division of gastroenterology): Positive reaction to RNA of type C hepatitis without symptoms.
