Brief Summary:
This is a multicenter, single-arm open-label, phase II study to evaluate the anti-tumor activity, safety, PK and immunogenicity of AK105 (Anti-PD1 antibody) in patients with metastatic nasopharyngeal carcinoma who have progressed after at least 2 prior lines of systemic chemotherapy (of which one of them must be platinum-based chemotherapy).

Arm Intervention/treatment
Experimental: AK105
Subjects receive AK105 200 mg intravenously (IV) once every 2 weeks (Q2W) until progression.
Biological: AK105
intravenous (IV) infusion

Primary Outcome Measures :
  1. Objective response rate (ORR) in the full analysis set (FAS) population [ Time Frame: up to 2 years ]
    ORR is defined as the proportion of subjects with confirmed CR or confirmed PR, based on RECIST Version 1.1.

  2. ORR in the PD-L1 positive population [ Time Frame: up to 2 years ]
    ORR is defined as the proportion of subjects with confirmed CR or confirmed PR, based on RECIST Version 1.1.

Secondary Outcome Measures :
  1. Progression-free survival (PFS) [ Time Frame: up to 2 years ]
    PFS is defined as the time from the date of randomization till the first documentation of disease progression (per RECIST v1.1 criteria) or death from any cause (whichever occurs first).

  2. Disease control rate (DCR) [ Time Frame: up to 2 years ]
    DCR is defined as the proportion of subjects with CR, PR, or SD, based on RECIST v1.1.

  3. Duration of response (DoR) [ Time Frame: up to 2 years ]
    DoR is defined as the duration from the first documentation of objective response to the first documented disease progression or death due to any cause, whichever occurs first.

  4. Overall survival (OS) [ Time Frame: up to 2 years ]
    OS is defined as the time from the date of randomization to death from any cause.

  5. Incidence and severity of treatment-emergent adverse events (TEAEs) [ Time Frame: From the time of informed consent signed through 90 days after last dose of AK105 ]
    An adverse event (AE) is any untoward medical occurrence or the deterioration of existing medical event in a clinical study subject administered an investigational drug, which does not necessarily have an unequivocal causal relationship with the investigational product.

  6. Observed concentrations of AK105 [ Time Frame: From first dose of AK105 through 90 days after last dose of AK105 ]
    The endpoints for assessment of PK of AK105 include serum concentrations of AK105 at different timepoints after AK105 administration.

  7. Number of subjects who develop detectable anti-drug antibodies (ADAs) [ Time Frame: From first dose of AK105 through 90 days after last dose of AK105 ]
    The immunogenicity of AK105 will be assessed by summarizing the number of subjects who develop detectable anti-drug antibodies (ADAs).

Layout table for eligibility information
Ages Eligible for Study:   18 Years to 70 Years   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Histologically confirmed diagnosis of nonkeratinizing differentiated or undifferentiated NPC.
  • Not suitable for radical local therapy.
  • Stage IVb metastatic NPC patients who have failed the first-line platinum-based chemotherapy and the second-line chemotherapy.
  • At least one measurable tumor lesion per RECIST 1.1 criteria. A lesion previously treated with local therapies such as radiotherapy can be considered a target lesion if there is objective evidence of progression in the lesion.
  • Subjects must provide an available tumor tissue sample taken within 3 years prior to enrollment.
  • Adequate organ function.
  • Females of childbearing potential who are sexually active with a nonsterilized male partner must use at least one highly effective method of contraception.
  • Nonsterilized males who are sexually active with a female partner of childbearing potential must use highly effective method of contraception from Day 1 and for 120 days after the last dose of investigational product.

Exclusion Criteria:

  • Receipt of last radiotherapy or any anti-tumor treatment [chemotherapy, targeted therapy, immunotherapy, Chinese herbal drugs with antitumor indications, or immunomodulators or tumor embolization] within 4 weeks prior to the first dose of study treatment. Nitrosourea or mitomycin C treatment within 6 weeks prior to the first dose of AK105.
