Nivolumab in Children and Adults With Nasopharyngeal Carcinoma

Summary

The purpose of this study is to assess whether the addition of the immune checkpoint inhibitor Nivolumab to induction chemotherapy will increase the percentage of patients with a complete response on MRI and PET after 3 cycles of induction therapy.

Eligibility

5. Written informed consent by legal guardians (if patient not ≥ 18 years) and patient prior to study participation

Exclusion Criteria:

2. Recurrent nasopharyngeal carcinoma
3. Nasopharyngeal carcinoma diagnosed as second malignancy and preceding chemotherapy and/or radiotherapy
4. Prior chemotherapy and/or radiotherapy
5. Other active malignancy
6. Prior treatment with an anti-PD-1, anti-PD-L1, anti-PD-L2, anti-CTLA-4 antibody, or any other antibody or drug specifically targeting T-cell co-stimulation or checkpoint pathways.
7. The subject received an investigational drug within 30 days prior to inclusion into this study
8. Subjects who are enrolled in another clinical trial
9. Subjects with prior organ allograft or allogenic bone marrow transplantation
10. Subjects with an active, known or suspected autoimmune disease. Participants with type I diabetes mellitus, hypothyroidism only requiring hormone replacement, skin disorders (such as vitiligo, psoriasis, or alopecia) not requiring systemic treatment, or conditions not expected to recur in the absence of an external trigger are permitted to enrol.
11. Subjects with a condition requiring systemic treatment with either corticosteroids (\> 10 mg daily prednisone equivalent) or other immunosuppressive medications within 14 days before start of therapy. Inhaled or topical steroids, and adrenal replacement steroid doses \> 10 mg daily prednisone equivalent, are permitted in the absence of active autoimmune disease.
12. Any positive test for hepatitis B virus or hepatitis C virus indicating acute or chronic infection
13. Known history of testing positive for human immunodeficiency virus (HIV) or known acquired immunodeficiency syndrome (AIDS).
14. Inadequate hematologic, renal or hepatic function defined by any of the following screening laboratory values:

    1. WBC \< 2 000/µl
    2. Neutrophils \< 1 500/µl
    3. Platelets \< 100 x 10e3/µL
    4. Hemoglobin \< 9.0 g/dL
    5. Creatinine \>1.5 x ULN or creatinine clearance \< 50 mL/min (using the Cockcroft Gault formula or Schwartz formula in patients \< 18 years)
    6. AST/ALT \> 3 x ULN (\> 5 x ULN if liver metastases)
    7. Total Bilirubin \> 1.5 x ULN (except subjects with Gilbert Syndrome who must have a total bilirubin level ≥ 3.0 x ULN)
15. Hearing loss \> 20 dB loss at 3 kHz due to an inner ear disorder and not caused by tumour burden
16. History of allergy or hypersensitivity to platinum-containing compounds or other study drug components
17. Clinically significant, uncontrolled heart disease (including history of any cardiac arrhythmias, e.g., ventricular, supraventricular, nodal arrhythmias, or conduction abnormality within 12 months of screening).
18. Vaccinated with live attenuated vaccines within 4 weeks of the first dose of the study drug.
19. Adequate performance status (Karnofsky score ≥ 60 for patients (age ≥ 16), Lansky score ≥ 60 (age \< 16).
20. The subject has a history of any other illness, which, in the opinion of the Investigator, might pose an unacceptable risk by administering study medication.
21. The subject has any current or past medical condition and/or required medication to treat a condition that could affect the evaluation of the study.
22. Pregnant females as determined by positive \[serum or urine\] hCG test at Screening or prior to dosing. Participants of child-bearing age should use adequate contraception as defined in the study protocol. (Please refer to section 4.4)
23. Lactating females
