Overview
Brief Summary
This study is a single-arm, open-label, exploratory dose-escalation and dose-finding clinical trial to evaluate the safety, efficacy, cellular pharmacokinetics and pharmacodynamics of CT0596 cells in patients with R/R MM and PCL.RRMM and RRpPCL
Detailed Description
This study is a single-arm, open-label, exploratory dose-escalation and dose-finding clinical trial to evaluate the safety, efficacy, cellular pharmacokinetics and pharmacodynamics of CT0596 cells in patients with R/R MM and PCL.RRMM and RRpPCL. During the trial, dose increases or decreases or dose expansion may be performed using i3+3 principle based on the safety and ,tolerability and PK data of the patients. All Patients will undergo a DLT assessment period which is defined as the first 28 days starting from the day of CT0596 infusion. A patient is evaluable for DLTs if the patient received the planned CT0596 dose and either completed the 28 days of DLT evaluation period after CT0596 infusion or experienced a DLT. Enrolled patients who are not evaluable for DLTs during dose escalation may be replaced. Any Patients who are not DLT evaluable will still be followed for safety and efficacy per the SOA.
Investigators
Eligibility Criteria
Inclusion Criteria
- •Participants must meet all of the following criteria to be enrolled:
- •Patients must voluntarily sign the informed consent form (ICF) and must be willing and be able to adhere to the trial visit schedule and other protocol requirements and agree to be in long term follow-up (LTFU) for up to 15 years as mandated by the regulatory guidelines.
- •Age ≥ 18 years;
- •Patients with R/RMM who have received at least 3 prior lines of therapy, including at least 1 proteasome inhibitor and at least 1 immunomodulator (IMiD). Patients with RRpPCL had received at least 1 prior line of therapy. Number of lines of therapy was defined according to the guidelines provided in Rajkuma\[1\]r 2015 . Patients must have received at least 1 complete cycle of therapy for each line of therapy.
- •According to multiple myeloma IMWG 2016 and plasma cell leukemia IMWG 2013, patients must have progressive disease following or during the last treatment.
- •Patients must have measurable disease based on at least one of the following parameters:
- •Expected survival \> 12 weeks;
- •Eastern Cooperative Oncology Group (ECOG) score 0- 1 ;
- •Patients should meet the following test results
- •Female patients of childbearing potential must have a negative pregnancy test at screening and prior to receiving lymphodepletion therapy and are willing to use a highly effective and reliable method of contraception for 1 year after receiving study treatment and are absolutely prohibited from donating eggs for 1 year after receiving study treatment infusion during the study ;Male patients are willing to use a highly effective and reliable method of contraception for 1 year after receiving study treatment if they are sexually active with a female of childbearing potential. Sperm donation is absolutely prohibited within 1 year following study treatment infusion for all male patients during the study.
Exclusion Criteria
- •Pregnant or lactating women;
- •Patient has any significant condition(s), laboratory abnormality or psychiatric illness that would impair the ability of the patient to receive or tolerate the planned treatment or in the opinion of the investigator, participation would not be in the best interest of the patient (eg, compromise the well-being) or that could prevent, limit, or confound the protocol-specified assessments
- •Patients seropositive for HIV, active hepatitis C virus (HCV), or active hepatitis B virus (HBV) infection. History of treated hepatitis B or C is permitted if the viral load is undetectable per qPCR and or nucleic acid testing;
- •Patients with any uncontrolled active infection, including but not limited to patients with active tuberculosis (investigator 's judgment);
- •Toxicities caused by previous treatment have not recovered to Common Terminology Criteria for Adverse Events (CTCAE) ≤ Grade 1, except alopecia and other events that are judged tolerable by the investigator;
- •Previous allogeneic stem cell transplantation; autologous stem cell transplantation within 12 weeks prior to signing informed consent;
- •Have received treatment for the disease within 14 days before informed consent
- •Have received cell therapy within 28 days before informed consent.
- •Systemic glucocorticoids equivalent to \> 15 mg/day prednisone within 7 days prior to informed consent, with the exception of topical glucocorticoids;
- •Vaccination with live attenuated vaccines , inactivated vaccines or RNA vaccines within 4 weeks prior to informed consent;
