Arm Intervention/treatment
Experimental: AK105

AK105 200 mg intravenously (IV) every-2-weeks (Q2W)




Primary Outcome Measures :
  1. Objective response rate (ORR) assessed by Independent Radiology Review Committee (IRRC) per the Lugano 2014 Classification [ Time Frame: Up to 2 years ]
    ORR defined as the proportion of subjects who achieves a best overall response of CR or PR, assessed by IRRC per the Lugano 2014 Classification.

  2. Number of subjects with adverse events (AEs) [ Time Frame: From the time of informed consent signed through 90 days after the last dose of AK105 ]
    An AE is defined as any untoward medical occurrence in a participant administered a pharmaceutical product temporally associated with the use of study treatment, whether or not considered related to the study treatment.


Secondary Outcome Measures :
  1. ORR assessed by Investigator [ Time Frame: Up to 2 years ]
    ORR defined as the proportion of subjects who achieves a best overall response of CR or PR, assessed by Investigator per the Lugano 2014 Classification.

  2. Duration of Response (DoR) [ Time Frame: Up to 2 years ]
    From the date that CR or PR are first occurred to the date of objective disease progression or death, whichever occurs first.

  3. Progression-free Survival (PFS) [ Time Frame: Up to 2 years ]
    From the first dose of AK105 to the date of the date of objective disease progression or death, whichever occurs first.

  4. Disease control rate (DCR) [ Time Frame: Up to 2 years ]
    DCR defined as the proportion of subjects response of CR, PR, or SD (subjects achieving SD will be included in the DCR if they maintain SD for ≥8 weeks) per the Lugano 2014 Classification.

  5. Minimum observed concentration (Cmin) of AK105 at steady state [ Time Frame: From first dose of AK105 through 30 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.

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

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  1. Written and signed informed consent
  2. Eastern Cooperative Oncology Group (ECOG) Performance Score of 0 or 1
  3. Histologically confirmed classic Hodgkin's lymphoma (cHL) (based on tumor tissue obtained within 3 years prior to enrollment).
  4. Relapsed (disease progression during or after most recent therapy) or refractory (failure to achieve CR or PR after most recent therapy) cHL and meet any of the following criterions:

    1. Recurrence or disease progression after autologous hematopoietic stem cell transplantation.
    2. For subject without receiving , the subject has received at least 2 lines of prior systemic chemotherapy. Refractory subject is defined as subject who has not achieved PR after at least 2 cycles of treatment, or subject who has not achieved CR after at least 4 cycles of treatment. If the best response to treatment is PD or the reason for ending the treatment is PD, the subject is consider as refractory without requirement on the number of cycles of treatment that the subject has received. For relapsed subjects, disease progression occurred for the subject who has received at least 2 line of prior systemic chemotherapy.
  5. Subject must have at least one measurable lesion (> 1.5 cm in the longest diameter, or > 1 cm in the longest diameter with uptake on 18FDG-PET)according to the Lugano 2014 criteria.
  6. Adequate organ functions.
  7. Use effective methods of contraception.

Exclusion Criteria:

  1. Known nodular lymphoma predominant Hodgkin lymphoma or Grey zone lymphoma.
  2. Lymphoma involving the central nervous system.
  3. Participated in other clinical studies of experimental drugs or received research treatment or used experimental equipment within 4 weeks prior to the first dose of AK105.
  4. Concurrent enrollment in another clinical study, unless it is an observational (non-interventional) clinical study or the follow-up period of an interventional study.
  5. Receipt of the last radiotherapy or the last dose of anticancer therapy (chemotherapy, target therapy, immunotherapy or tumor embolism, etc.) with 4 weeks prior to the first dose of AK105. Receipt of the last dose of nitrocarbamide or mitomycin C within 6 weeks prior to the first dose of AK105.
  6. Prior exposure to any anti-PD-1, anti-PD-L1, anti-CTL4 antibody or any other antibody or drug targeting T-cell costimulation or checkpoint pathways such as ICOS, or agonists such as CD40, CD137, GITR, OX40 etc..
