Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

14 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Key Inclusion Criteria:

  1. Age ≥18 years.
  2. Relapsed or refractory multiple myeloma, as defined by IMWG response criteria and treatment with at least 2 prior lines of therapy.
  3. Eastern Cooperative Oncology Group performance status 0 or 1.
  4. Adequate renal, liver, cardiac and pulmonary organ function
  5. Female subjects of childbearing potential and male subjects must agree to use acceptable method(s) of contraception from enrollment through at least 12 months after CTX120 infusion.

Key Exclusion Criteria:

  1. Prior allogeneic stem cell transplant (SCT).
  2. Less than 60 days from autologous SCT at time of screening and with unresolved serious complications.
  3. Prior treatment with any gene therapy or genetically modified cell therapy, including CAR T cells or natural killer cells, or BCMA-directed therapy.
  4. Evidence of direct central nervous system (CNS) involvement by multiple myeloma.
  5. History or presence of clinically relevant CNS pathology such as a seizure disorder, cerebrovascular ischemia/hemorrhage, dementia, cerebellar disease, any autoimmune disease with CNS involvement.
  6. Unstable angina, clinically significant arrhythmia, or myocardial infarction within 6 months of enrollment.
  7. Active HIV, hepatitis B virus or hepatitis C virus infection.

  9. Use of systemic anti-tumor therapy or investigational agent within 14 days prior to enrollment.
  10. Primary immunodeficiency disorder or active autoimmune disease requiring steroids and/or other immunosuppressive therapy.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Part A (dose escalation): Incidence of adverse events
Time Frame: From CTX120 infusion up to 28 days post-infusion
Adverse events defined as dose-limiting toxicities
From CTX120 infusion up to 28 days post-infusion
Part B (cohort expansion): Objective response rate
Time Frame: From CTX120 infusion up to 60 months post-infusion
Objective response rate per International Myeloma Working Group (IMWG) response criteria.
From CTX120 infusion up to 60 months post-infusion

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
Progression Free Survival
Time Frame: From date of CTX120 infusion and date of disease progression or death due to any cause, assessed up to 60 months
From date of CTX120 infusion and date of disease progression or death due to any cause, assessed up to 60 months
Overall Survival
Time Frame: From date of CTX120 infusion until date of death due to any cause, assessed up to 60 months
From date of CTX120 infusion until date of death due to any cause, assessed up to 60 months

Study Major Dates

Study Start (Actual)

Study Start

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit).
