Details and patient eligibility

About

This is a pilot study investigating the role of nivolumab, a PD-1 inhibitor, in the treatment of advanced stage or relapsed/refractory NKTL. Patients who have received PD-1 inhibitors will be excluded from this study.

Patients who have a complete response or good partial response to nivolumab during initial phase will continue to be treated with nivolumab. Patients who have a partial response, stable disease, and progressive disease to nivolumab during initial phase will be treated with the combination of nivolumab and GDP/L-asparaginase.

Sex: All

Ages: 21 to 80 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Signed written informed consent

  • Subjects must have signed and dated and IRB-approved written consent form in accordance with regulatory and institutional guidelines. This must be obtained before the performance of any protocol-related procedures that are not part of normal subject care
  • Subjects must be willing and able to comply with scheduled visits, treatment schedule, laboratory tests and other requirements of the study

• Target population

  • All subjects must have histologically confirmed extranodal natural-killer/T-cell lymphoma (NKTL)

  • Subjects must have

    • previously untreated stage III or IV NKTL, OR

    • relapsed/refractory NKTL who has received at least 2 cycles of one prior regimen or previous radiotherapy administered with curative intent and one of the following:

      • Failed to achieve at least a partial response
      • Failed to achieve a complete response at the end of planned therapy with curative intent
      • Progressed after initial response

  • Age ≥ 21 years

  • ECOG Performance status 0 - 2

  • Subjects must have laboratory test results within these ranges:

    • Absolute neutrophil count (ANC) ≥ 1.5 x10^9/L
    • Platelet count ≥ 75 x10^9/L
    • Creatinine clearance ≥ 40ml/min
    • Total bilirubin ≤ 1.5 x upper limit of normal (ULN). Higher levels are acceptable if these can be attributed to active haemolysis or ineffective erythropoiesis
    • Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) ≤ 2x ULN

• Women of childbearing potential (WOCBT) must agree to use dual methods of contraception and have a negative serum or urine pregnancy test prior study treatment. Male patients must use an effective barrier method of contraception if sexually active with a WOCBT

Exclusion criteria

• Previous treatment with an anti PD-1, anti PD-L1, anti PD-L2, anti-CD137, or anti-CTLA-4 antibody or any other antibody or drug specifically targeting T-cell co-stimulation or checkpoint pathways
• Previous GDP therapy
• Previous serious hypersensitivity reaction or symptomatic pancreatitis from L-asparaginase
• Uncontrolled central nervous (CNS) disease
• Uncontrolled hepatitis B or C
• Known history of positive test for human immunodeficiency virus (HIV) or known acquired immunodeficiency syndrome (AIDS)
• All toxicities attributed to prior anti-cancer therapy other than alopecia and fatigue must have resolved to grade 1 (NCI CTCAE version 4) or baseline before administration of study drug
• Subjects with > grade 1 peripheral neuropathy
• Any serious or uncontrolled medical disorder, autoimmune disorder or active infection that, in the opinion of the investigator, may increase the risk associated with study participation, study drug administration or would impair the ability fo the subject to receive the study drug
• Subjects who have had prior malignancies (other than NKTL) for ≤5 year with exception of currently treated basal cell, squamous cell carcinoma of the skin or carcinoma "in situ" of the cervix or breast.
• Subjects who have had other anti-cancer therapy including radiation or experimental drug therapy within 28 days of enrollment
• Subjects with known allergies or hypersensitivities to the study drugs
• Prisoners or subjects who are involuntarily incarcerated
• Subjects who are compulsorily detained for treatment of either a psychiatric or physical (e.g., infectious disease) illness
• Pregnant women or women who are breastfeeding are excluded from this study

0 participants in 2 patient groups

Nivolumab

Experimental group

Description:

After 4 doses of nivolumab, if the patient has complete responses (CR) or good partial response (PR), the patient will continue on nivolumab until disease progression, unacceptable toxicities, or discontinuation of treatment. During PET4-directed treatment with single agent nivolumab, if patient has PD, they will proceed to the Nivo+GDP/L-aspa arm.

Treatment:

Drug: IV Nivolumab

Drug: IV Nivolumab

Nivolumab + GDP/ L-asparaginase

Experimental group

Description:

After 4 doses of nivolumab, if the patient has PR, stable disease (SD), or progressive disease (PD), the patient will switch to nivolumab-GDP/L-aspa treatment. After 6 cycles of treatment, if CR is achieved, the patient will continue on single agent nivolumab until disease progression, unacceptable toxicities, or discontinuation of treatment.

Treatment:

Drug: IV/PO Dexamethasone

Drug: IV Nivolumab

Drug: IV Cisplatin

Drug: IV L-asparaginase

Drug: IV Nivolumab

Drug: IV Gemcitabine
