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.

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
Complete Response (CR)
Time Frame: 2 years

Each participant's response to treatment will be assessed per the Lugano criteria. The criteria are:

  • Complete Response (CR): Complete disappearance of all lesions, evidence, and effects of disease
  • Partial Response (PR): ≥50% decrease in SPD of the 6 largest lesions with no increase in the size of the other nodes; splenic / hepatic nodules regress ≥50%, and with no new sites of disease
  • Stable disease (SD): less than PR.
  • Progressive disease (PD): sum of the product of dimensions (SPD) of lesions increased ≥50% from smallest value The outcome will be reported as the number of participants with a CR after 4 and 8 cycles of treatment (4 and 8 months), and if CR is achieved anytime within 2 years ("overall").
2 years

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
Measure Description
Time Frame
Magrolimab related Adverse Events
Time Frame: 4 months
Magrolimab safety and tolerability will be assessed on the basis of magrolimab related adverse events occurring within 4 cycles of treatment (4 months). The outcome will be reported as the number of magrolimab related adverse events judged mild (Grade 1), moderate (Grade 2), severe (Grade 3), life threatening (Grade 4), or fatal (Grade 5), numbers without dispersion.
4 months

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Overall Response (OR)
Time Frame: 8 months

Overall response (OR) is defined as the sum of participants who achieve a complete response (CR) plus the number of participants who achieve a partial response (PR). Treatment response will be assessed per the Lugano criteria (aka the Cheson criteria). The criteria are:

  • CR: Complete disappearance of all lesions, evidence, and effects of disease
  • PR: ≥50% decrease in SPD of the 6 largest lesions with no increase in the size of the other nodes; splenic / hepatic nodules regress ≥50%, and with no new sites of disease
  • Stable disease (SD): less than PR.
  • Progressive disease (PD): sum of the product of dimensions (SPD) of lesions increased ≥50% from smallest value The outcome will be reported as the number of participants with either a CR or a PR after 4 and 8 cycles of treatment (4 and 8 months). For participants who undergo a subsequent stem cell transplant, the value will be recorded as the time to transplant (censored).
