Brief Summary:

YH004 is a humanized monoclonal antibody that specifically binds to 4-1BB, and acts as an agonist against 4-1BB.

This first in human study of YH004 is designed to establish the maximum tolerated dose (MTD) and/or the recommended Phase II dose (RP2D) of YH004, both as a single agent (monotherapy) and in combination with a fixed dose of anti-PD-1 antibody (Toripalimab) in the treatment of advanced solid tumors and relapsed or refractory non-Hodgkin Lymphoma.


Condition or disease Intervention/treatment Phase
Cancer Drug: YH004 Phase 1

Detailed Description:
This is an open-label, non-randomized, two-stage, FIH Phase 1 study, utilizing an accelerated dose escalation followed by a traditional 3 + 3 dose escalation algorithm to identify the MTD and/or RP2D of YH004 as a single agent (monotherapy) and in combination with Toripalimab. The first stage of the study is the dose escalation phase (i.e., Phase 1a). The second stage of the study is the dose expansion phase (i.e., Phase 1b). During the study, dose interruption(s) and/or delay(s) may be implemented based on toxicity. Dose modifications are permitted following protocol guidelines. Intra-patient dose escalations will be allowed for the early dose cohorts (single-patient dose groups) in Phase 1a. Patients will be considered evaluable for safety and tolerability if they receive at least one dose of YH004 or Toripalimab at the specified cohort dose. Patients in all parts of the trial will remain on therapy until confirmed disease progression or for 1 year, whichever occurs first. However, patients who are clinically unstable will discontinue following the initial assessment of disease progression.

Arm Intervention/treatment
Experimental: YH004
The dose escalation phase includes 7 dose levels of YH004, and the highest dose is up to 10mg/kg. Route of administration is IV infusion, and the frequency of administration is once every 3 weeks (Q3W). one cycle is 3 weeks, and treatment can be up to 16 cycles if patients receive benefits.
Drug: YH004
IV infusion once every 3 weeks (Q3W).




Primary Outcome Measures :
  1. Treatment-emergent adverse events (TEAEs) including determination of DLTs and serious AEs (SAEs) [ Time Frame: up to 24 months ]
    Adverse events will be assessed, and severity will be assigned by using the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) v5.0

  2. Maximum tolerated dose (MTD) and/or the recommended Phase II dose (RP2D) [ Time Frame: up to 24 months ]
    The MTD and/or RP2D will be determined based on TEAEs
