Arm Intervention/treatment
Experimental: Dose-Escalation Stage
Participants will be assigned sequentially to escalating doses of BLYG8824A, up to the maximum tolerated dose (MTD).
 Drug: BLYG8824A
BLYG8824A will be administered at a flat dose independent of body weight.
Experimental: Dose-Expansion Stage
Once dose escalation is completed and the MTD (or MAD) has been identified, a recommended expansion dose will be proposed for the dose-expansion stage of the trial.
 Drug: BLYG8824A
BLYG8824A will be administered at a flat dose independent of body weight.


Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Incidence and Nature of DLTs [ Time Frame: Approximately 48 months ]
  2. Number of Patricipants with Adverse Events [ Time Frame: Approximately 48 months ]
  3. Number Of Cycles Received [ Time Frame: Approximately 48 months ]
  4. Dose Intensity [ Time Frame: Approximately 48 months ]
  5. Maximum Tolerated Dose(s) MTD(s) of BLYG8824A [ Time Frame: Approximately 48 months ]

Secondary Outcome Measures :
  1. Serum Concentration of BLYG8824A [ Time Frame: At predifined interevals from Cycle 1 Day 1; Cycle 2 Day 1; Cycles ≥ 3, Day 1; Treatment Completion/ Discontinuation (Cycle length: 21 days) ]
  2. Overall Response Rate (ORR) [ Time Frame: Approximately 48 months ]
    ORR is defined as the proportion of patients with a complete response (CR) or partial response (PR) as determined by the investigator according to Response Evaluation Criteria in Solid Tumors, Version 1.1 (RECIST v1.1)

  3. Duration of Response (DOR) [ Time Frame: Approximately 48 months ]
    Duration of response (DOR), defined as the time from the first occurrence of a documented objective response to disease progression or death from any cause (whichever occurs first), as determined by the investigator according to RECIST v1.1

  4. Presence of Anti-drug Antibodies (ADAs) [ Time Frame: Cycle 1, Day 1; Cycle 2 Day 1; Cycles ≥ 3, Day 1; Treatment Completion/ Discontinuation (Cycle length: 21 days) ]

  • For patients enrolled in either a dedicated biopsy cohort or other expansion cohorts where biopsy is clinically feasible, willingness to consent to mandatory fresh pretreatment and on-treatment biopsies of safely accessible tumor lesions

Exclusion Criteria:

  • Pregnant or breastfeeding, or intending to become pregnant during the study or within 4 months after the final dose of BLYG8824A
