NCT07185490

Brief Summary

This study is a single-center, open-label, dose-exploration trial designed to evaluate the tolerability and safety of different doses of IASO104 in patients with relapsed/refractory plasma cell neoplasms, determine the recommended dose of IASO104, and assess its pharmacokinetic and pharmacodynamic characteristics. Additionally, the study will preliminarily observe the efficacy of the investigational drug in a small sample of subjects with relapsed/refractory multiple myeloma.

Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Age 18-75 years, any gender.
  • Diagnosis of multiple myeloma (MM) per International Myeloma Working Group (IMWG) diagnostic criteria.
  • Prior therapy requirements:
  • MM patients: ≥3 prior lines of therapy, including:
  • proteasome inhibitor (PI)
  • immunomodulatory drug (IMiD)
  • anti-CD38 monoclonal antibody Exception: No minimum line requirement for subjects refractory to PIs, IMiDs, and anti-CD38 therapy.
  • Primary plasma cell leukemia (pPCL): ≥1 prior line including ≥1 PI and ≥1 IMiD.
  • Documented disease progression during/within 12 months after last anti-myeloma therapy (exemption: No 12-month requirement if last line was CAR-T).
  • Measurable disease at screening (≥1 of the following):
  • Serum M-protein:
  • IgG ≥10 g/L IgA/IgD/IgE/IgM ≥5 g/L Urine M-protein ≥200 mg/24h Serum free light chains (FLC): Involved FLC ≥100 mg/L with abnormal κ/λ ratio Bone marrow plasma cells ≥30% (if no measurable M-protein/FLC).
  • ECOG performance status 0-1.
  • Life expectancy ≥12 weeks.
  • Adequate organ function (all lab values within 7 days prior to enrollment):
  • +8 more criteria

You may not qualify if:

  • Active graft-versus-host disease (GVHD) or requiring long-term immunosuppressive therapy.
  • Prior hematopoietic stem cell transplantation (HSCT):
  • Autologous HSCT (Auto-HSCT) within 12 weeks before apheresis,
  • ≥2 prior Auto-HSCTs, Any prior allogeneic HSCT (Allo-HSCT).
  • Prior cell therapy targeting plasma cells within 3 months before apheresis, or detectable residual cellular therapy products in peripheral blood.
  • Recent anti-myeloma therapies (relative to apheresis):
  • Monoclonal antibody treatment within 21 days, Cytotoxic chemotherapy or proteasome inhibitors within 14 days, Immunomodulatory drugs within 7 days, Other anti-tumor therapies within 14 days or 5 half-lives (whichever is shorter).
  • Chronic corticosteroid use (\>20 mg/day prednisone or equivalent), except for physiologic replacement, topical, or inhaled use.
  • Uncontrolled hypertension despite medication.
  • Severe cardiac disease, including:
  • Unstable angina, Myocardial infarction (within 6 months before screening), Congestive heart failure (NYHA Class ≥III), Severe arrhythmias.
  • Unstable systemic illnesses per investigator's judgment (e.g., severe hepatic, renal, or metabolic disorders requiring medication).
  • Other malignancies within 5 years, excluding:
  • Carcinoma in situ of the cervix, Basal/squamous cell skin cancer, Localized prostate cancer post-radical resection, Ductal breast carcinoma in situ post-resection.
  • History of solid organ transplantation.
