Outcome Measures
Primary Outcomes (2)
Number of Participants With Adverse Events according to CTCAE V5.0
An adverse event (AE) was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. A serious adverse event (SAE) is an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly.
up to approximately 2 years
Number of Participants With Dose Limiting Toxicities (DLTs)
DLTs were assessed using the national cancer institute common terminology criteria for adverse events (NCI-CTCAE) version 5.0.
From the time of first dosing (Day 1) until the forth dosing (Day 28)
Secondary Outcomes (13)
Area under the curve (AUC) of Y150
Up to 1 weeks after the fourth dosing.
Peak Plasma Concentration (Cmax) of Y150
Up to 1 weeks after the fourth dosing.
Half-time (t1/2) of Y150
Up to 1 weeks after the fourth dosing.

Study Arms (1)
Y150
EXPERIMENTALSubjects who meet the enrollment criteria will enter the core treatment period and receive a cycle of treatment with Y150 (once weekly for 4 weeks) via intravenous infusion. And eligible subjects who complete the core treatment period will receive a cycle of extended treatment (once weekly for 4 weeks) until disease progression or toxicity intolerance.
Interventions
Subjects will receive an intravenous infusion of Y150 in a dose escalation once a week for a 28-day treatment cycle until confirmed progression, unaccepted toxicity, or any criterion for withdrawal from the study.
Eligibility Criteria
You may qualify if:
- Male or female ≥ 18 years.
- Subject has a history of multiple myeloma with relapsed and refractory disease, and must have received at least 2 prior multiple myeloma treatment regimens (including a proteasome inhibitor and an immunomodulatory agent), or can not tolerate the toxicity of PIs and IMIDS; or have drug resistance to one and toxic intolerance to the other.
- Relapsed multiple myeloma is defined as IMWG criteria in 2016, including clinical relapse or relapse after CR.
- Refractory multiple myeloma is defined as failure of initial or salvage therapy to achieve at least a minimal response (only achieve SD after treatment ≥ 2 cycles ), or disease progression during treatment or within 60 days after the last treatment.
- Subjects must have measurable disease, including at least one of the criteria below:
- M-protein ≥ 10 g/L by SPEP/immunofixation for subjects with immunoglobulin class G (IgG) myeloma , M-protein ≥ 5g/L for subjects with IgA, IgD, IgE, IgM myeloma or
- ≥ 200 mg/24 hours urine collection by UPEP or
- Serum free light chain (FLC) levels ≥ 100 mg/L and an abnormal kappa/lambda (κ/λ) ratio in patients without detectable serum or urine M-protein
- The interval between the last anti-tumor treatment and the first administration of Y150 (including PIS and IMADs) ≥4 weeks, the interval between CD38 mAb administration and the first administration of Y150 ≥12 weeks;
- ECOG performance status 0 - 2;
- Life expectancy ≥ 3 months
- Adequate hematological function as evidenced by meeting all the following requirements:
- Absolute neutrophil count ≥1.0×109/L (growth factor support not allowed within 48h)
- Hemoglobin \> 70 g/L( without blood transfusion within 7 days)
- Platelet count ≥50×109/L(without transfusion within 7 days)
- +5 more criteria
You may not qualify if:
- Subject has central nervous system involvement of multiple myeloma.
- Subject has received ≥ 10 mg/day prednisone equivalent within one week before starting Y150.
- Subject with primary or secondary plasma cell leukemia.
- Subject had a prior autologous stem cell transplant ≤ 12 weeks months prior to starting Y150, or had a prior autologous stem cell transplant history.
- Subject received a chimeric antigen receptor T (CAR T) cell product ≤ 6 months prior to starting Y150.
- Concurrent malignancy within 5 years prior to entry other than adequately treated cervical carcinoma-in-situ, localized squamous cell cancer of the skin, basal cell carcinoma, prostate cancer under active surveillance, prostate cancer that has undergone definitive treatment, ductal carcinoma in situ of the breast, or ≤ T1 urothelial carcinoma.
- Allergy to Abs drugs or human protein.
- Active infection(CTCAE Grade ≥2).
- Subjects with severe respiratory disease, and to be unsuitable to participate in study by investigators judgment.
- Severe cardiovascular disease, including a history of CABG or PCI, myocardial infarction within 6 months of study entry, unstable angina ,NYHA class III or IV heart failure, uncontrolled hypertension or left ventricular ejection fraction \<50%
- QTc interval \> 480 ms; Family or personal with a history of long or short QT syndrome; significant clinical history of ventricular arrhythmias, or currently receiving antiarrhythmic drugs or implanted defibrillator to treat ventricular arrhythmias.
- Patients with a history of active autoimmune diseases (e.g., inflammatory bowel disease, idiopathic thrombocytopenic purpura, lupus erythematosus, hemolytic anemia, scleroderma, severe psoriasis, rheumatoid arthritis etc.), except when the disease is in a stable state (without systemic immunosuppressant treatment, the symptoms are stable for more than 6 months).
- Patients with severe hyperthyroidism or hypothyroidism.
- Patients with metabolic diseases such as uncontrolled diabetes, severe gastrointestinal bleeding, severe diarrhea (Grade ≥ 2 according to CTCAE), or severe gastrointestinal obstruction requiring intervention.
- Patients with a history of immunodeficiency, including HIV positive.
