Phase II, pilot, open-label, prospective, multicenter, non-randomized study to evaluate the safety and efficacy of ARI0002h (cesnicabtagene autoleucel) in 20 patients with newly diagnosed primary plasma cell leukemia (PCL).
The study population is patients between 18 and 75 years of age with newly diagnosed primary plasma cell leukemia (pPCL), with a life expectancy of more than 3 months.
The primary objective is to assess the safety and efficacy of CARTBCMA ARI0002h (cesnicabtagene autoleucel) after initial treatment to induce response in patients with newly diagnosed primary plasma cell leukaemia.
Patients between 18 and 75 years old diagnosed with newly diagnosed primary plasma cell leukemia (the presence of 5% or more circulating plasma cells in peripheral blood smears in patients otherwise diagnosed with symptomatic multiple myeloma), according to International Myeloma Working Group (IMWG).
Disease measurable at diagnosis by monoclonal component in serum or urine, or by free light chains in serum according to the eligibility criteria for clinical trials of the "International Myeloma Working Group".
ECOG Performance Status from 0 to 2
Life expectancy greater than 3 months.
No previous treatments, except for induction therapy for primary plasma cell leukemia.
Administration of any anti-BCMA therapy as part of induction
Not having achieved at least a minimal response with induction treatment (IMWG criteria)
Absolute lymphocyte count <0.1x109/L
