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.

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

20 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Patients aged 20 years or older at the submission of the written informed consent form
  • Patients that have undergone therapy after at least 2 prior systemic therapies (anti-CD20 Ab, chemo, and so on) for relapsed or refractory B-cell NHL
  • Patients who have not undergone phosphatidylinositol 3-kinase (PI3K) inhibitors to date
  • Patients who have not undergone Bruton's tyrosine kinase (BTK) inhibitors to date
  • Patients with Eastern Cooperative Oncology Group Performance status (ECOG PS) "0 or 1"

Exclusion Criteria:

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: ME-401
Drug: ME-401
In the first 2 cycles (1 cycle is 28 days), subjects will be administered 60 mg of ME-401 orally once a day on a continuous schedule (CS). After that, subjects will be administered 60 mg of ME-401 orally once a day for the first 7 days, followed by rest for 21 days on an intermittent schedule (IS).

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
Objective response rate (ORR)
Time Frame: Up to approximately 2 years
ORR is measured as the proportion of subjects achieving the best response rating of complete response (CR) or partial response (PR) prior to first progressive disease (PD).
Up to approximately 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
Time Frame
Efficacy of ME-401 as assessed by the duration of response (DOR)
Time Frame: Up to approximately 4 years
Up to approximately 4 years
Efficacy of ME-401 as assessed by the progression-free survival (PFS)
Time Frame: Up to approximately 4 years
Up to approximately 4 years
Efficacy of ME-401 as assessed by CR
Time Frame: Up to approximately 4 years
Up to approximately 4 years
Efficacy of ME-401 as assessed by the Time to treatment failure (TTF)
Time Frame: Up to approximately 4 years
Up to approximately 4 years
Efficacy of ME-401 as assessed by the objective response rate (ORR)
Time Frame: Up to approximately 4 years
Up to approximately 4 years
Safety of ME-401 as assessed by the number of participants with treatment-emergent adverse events (TEAEs)
Time Frame: Up to approximately 4 years
Up to approximately 4 years
Safety of ME-401 as assessed by the time to occurrence of adverse event of special interest (AESI)
Time Frame: Up to approximately 4 years
Up to approximately 4 years
Plasma concentration level of ME-401

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
September 17, 2020

Primary Completion (Estimated)

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 (Estimated)

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). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
