About this trial
This study aims to provide a basis for further clinical development of YKST02. YKST02 is a study medicine that targets multiple myeloma and activates the human body to fight against this disease.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Participants or their legally acceptable representative must sign an ICF indicating that the participants understand the purpose of, and procedures required for the study and are willing to participate in the study.

Disqualifiers
Plasma cell leukemia (>2.0×10^9/L plasma cells by standard differential), Waldenstrom's Macroglobulinemia, POEMS syndrome (polyneuropathy, organomegaly, endocrinopathy, monoclonal protein, and skin changes), or primary light-chain amyloidosis.
Targeted therapy with small molecule drug within 2 weeks or 5 half-lives, whichever is longer;
Targeted therapy with macromolecular drug or Immunomodulatory agent therapy within 2 weeks;
Chemotherapy within 2 weeks;

Trial outcomes
Primary outcomes
Number of Participants with Dose-limiting Toxicities (DLT)
The Dose Limiting Toxicities (DLTs) are based on drug related adverse events and are specifically defined in study protocol.
Incidence of Adverse Events (AEs)
An AE is defined as any untoward medical event that occurs after a subject receives the investigational drug, which may be manifested as symptoms, signs, diseases, or laboratory abnormalities, but may not necessarily have a causal relationship with the investigational drug.
Incidence of Serious Adverse Events (SAEs)
A SAE refers to an untoward medical occurrence such as death, life-threatening event, permanent or serious disability or loss of function, need for hospitalization or prolongation of hospitalization after the subject receives the investigational drug, and congenital abnormalities or birth defects.
Overall Response Rate (ORR)
Measured by IMWG criteria, only applicable in dose expansion phase
Secondary outcomes
Area under the Concentration-time Curve (AUC) after Administration
AUC of YKST02
Maximum Serum Concentration (Cmax) of YKST02
Cmax is defined as the maximum observed serum concentration of YKST02
Time to Cmax of YKST02 (Tmax)
Time to maximum serum concentration (Tmax) of YKST02
