Arm Intervention/treatment
Experimental: Experimental
KL-A167 900 mg intravenously (IV) every-2-weeks (Q2W)
Drug: KL-A167 Injection
KL-A167 900 mg intravenously (IV) every-2-weeks (Q2W)




Primary Outcome Measures :
  1. Objective Response Rate (ORR) assess by Independent Review Committee (IRC) [ Time Frame: from first patient first visit to 6 month after last patient first visit ]
    Based on Response Evaluation Criteria in Solid Tumors 1.1 (RECIST 1.1)


Secondary Outcome Measures :
  1. ORR assess by investigators [ Time Frame: from first patient first visit to 6 month after last patient first visit ]
    Based on Response Evaluation Criteria in Solid Tumors 1.1 (RECIST 1.1) and Immune-related Response Evaluation Criteria In Solid Tumors 1.1 (irRECIST 1.1)

  2. Progression-Free Survival (PFS) [ Time Frame: up to approximately 1 year ]
    PFS as measured in accordance with the Response Evaluation Criteria In Solid Tumours (RECIST) version 1.1

  3. Overall Survival (OS) [ Time Frame: up to approximately 1 year ]
    Overall Survival is defined as the time from registration to death due to any cause, or censored at date last known alive

  4. Disease Control Rate (DCR) [ Time Frame: from first patient first visit to 6 month after last patient first visit ]
    Based on Response Evaluation Criteria in Solid Tumors 1.1 (RECIST 1.1)

  5. Duration of Response (DOR) [ Time Frame: up to approximately 1 year ]
    Based on Response Evaluation Criteria in Solid Tumors 1.1 (RECIST 1.1)

  6. Time to Response(TTR) [ Time Frame: from first patient first visit to 6 month after last patient first visit ]
    From the date of the first dose of KL-A167 to the time the response criteria are first met
