7H-15-3 PhII-136 Multicenter Phase II Study of Nivolumab in Previously Treated Patients with Recurrent and Metastatic Nasopharyngeal Carcinoma

Description

PRIMARY OBJECTIVES: I. Objective tumor response to nivolumab in patients with previously treated recurrent and/or metastatic nasopharyngeal carcinoma (NPC) based on Response Evaluation Criteria in Solid Tumors (RECIST) criteria version 1.1. SECONDARY OBJECTIVES: I. Tumor response to nivolumab based on immune-related response criteria (IRC). II. Duration of response. III. Progression-free survival and overall survival. IV. Safety and tolerability. TERTIARY OBJECTIVES: I. To investigate the effect of nivolumab on tumor burden by analyzing the clearance of plasma Epstein-Barr virus (EBV) deoxyribonucleic acid (DNA) during the first 4-6 weeks of treatment. II. To investigate the association between treatment outcome and immunological markers: a) Intratumoral expression of programmed cell death 1 (PD-1) and programmed cell death-ligand (PD-L1) in archived NPC tissues (mandatory); b) Serum absolute lymphocyte count at baseline and post-treatment (mandatory); and c) Plasma cytokine levels at baseline and serially during the first 8 weeks of treatment; d) Expression of PD-1 in cluster of differentiation (CD)8+ T cells in tumor infiltrating lymphocytes (TIL) at baseline (optional). III. To investigate functional magnetic resonance imaging (MRI) sequences as an early predictor of response to nivolumab (optional only at Chinese University of Hong Kong [CUHK]). OUTLINE: Patients receive nivolumab intravenously (IV) over approximately 60 minutes on days 1 and 15. Courses repeat every 4 weeks in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up for 3 years.

Phase

Phase 2 - takes the treatment one step further, assessing the activity of a particular therapy in a disease, often building upon leads from the Phase I trial. While patients are generally required to be previously untreated, participation in a Phase II trial doesn't usually preclude the patient from getting the standard treatment after they've received the investigational agent. At best they are allowed to get a new drug they wouldn't be able to get otherwise that may turn out to be better for their disease.

  • Mitomycin C =< 6 weeks prior to registration
  • Those who have not recovered from adverse events (to grade =< 1 in severity) due to agents administered more than 4 weeks earlier; prior palliative radiotherapy to bone metastases =< 2 weeks prior to registration (i.e. prior palliative radiotherapy to bone metastases is allowed if it is performed > 2 weeks prior to registration)
  • Prior investigational agents =< 4 weeks prior to registration
  • Prior treatment with an anti-PD-1, anti-PD-L1, anti-PD-L2, anti-cytotoxic T-lymphocyte antigen 4 (CTLA-4) antibody, or any other antibody or drug specifically targeting T-cell co-stimulation or immune checkpoint pathways
  • Known brain metastases or leptomeningeal metastases; NOTE: symptomatic, and/or if they require immunosuppressive doses of corticosteroids (e.g. > 10 mg/day prednisone or equivalents) for at least 2 weeks prior to study drug administration; patients with treated brain metastases who are deemed clinically stable and without radiological progression on positron emission tomography (PET), MRI or computed tomography (CT) scan performed =< 8 weeks of study entry, are not excluded; NOTE: primary nasopharyngeal cancers that directly invade the skull base and extend into the infratemporal fossa (e) are not regarded as brain metastases and are not excluded
