About this study
Official title: A Phase 1/2a Open-label, Dose-Escalation Study to Investigate the Safety and Tolerability, Efficacy, Pharmacokinetics, and Immunogenicity of TAK-079 Administered Subcutaneously as a Single Agent in Patients With Relapsed/Refractory Multiple Myeloma
The purpose of this study is to assess the safety and tolerability, maximum tolerated dose (MTD)/recommended phase 2 dose (RP2D) of TAK-079 monotherapy and when combined with a backbone regimen of pomalidomide and dexamethasone (PomDex) in Phase 1, and to provide a preliminary evaluation of the clinical activity of TAK-079 monotherapy in Phase 2a in participants with r/r MM.
Read the detailed description
The drug being tested in this study is called TAK-079. TAK-079 is being tested to treat people who have relapsed and/or refractory multiple myeloma (RRMM). This study will assess the safety, tolerability, efficacy, pharmacokinetics, and immunogenicity of TAK-079 monotherapy and will provide a preliminary assessment of its activity against MM. The study is designed to consist of 2 phases: Phase 1 and Phase 2a.
The study could enroll approximately 100 participants. The study population of Phase 1 will consist of approximately 55 participants. Participants in Phase 1 will be assigned to TAK-079 and dose-escalation will range from 45 mg to 1800 mg.
The study population of Phase 2a will consist of approximately 48 participants. Dose for Phase 2a will be based upon review of the available safety, efficacy, pharmacokinetic, and pharmacodynamic data from the preceding cohorts of Phase 1.
This multi-center trial will be conducted in the United States. The overall time to participate in this study is 42 months (3.5 years). In Phase 1, participants who stop treatment for any other reason other than PD will continue to have progression-free survival (PFS) follow-up at the site every 4 weeks from the last dose of study drug up to 12 months or until PD, death, loss to follow-up, consent withdrawal or study termination. Participants will be followed 30 days after last dose of study drug or until the start of subsequent alternative anti-cancer therapy, whichever occurs first, for a follow up assessment.

What is being measured
The primary outcome is the main question the study is designed to answer.
Phase 1: Number of Participants Reporting One or More Treatment-emergent Adverse Events (TEAEs)
TEAEs were any untoward medical occurrence (called an adverse event [AE]) that occurred after administration of the first dose of any study drug and through 30 days after the last dose of any study drug.
Measured: From the first dose of study drug through 30 days after the last dose (up to approximately 3.7 years)
Phase 1: Number of Participants With Dose-limiting Toxicities (DLTs)
DLTs were defined as any of the following events: Grade 4 laboratory abnormalities, except those events that were clearly due to extraneous causes; nonhematologic TEAEs of grade greater than or equal to (>=3) except grade 3 nausea/vomiting, fatigue lasting less than 72 hours, elevation of alanine aminotransferase (ALT) or aspartate aminotransferase (AST) that resolves to grade less than or equal to (<=)1 or baseline within 7 days, injection reaction (IR) that responds to symptomatic treatment; Hematologic TEAEs of National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) grade >=4, except grade >=3 hemolysis, grade 3 low platelet or higher count with clinically meaningful bleeding; and an incomplete recovery from treatment-related toxicity causing a greater than (>) 2-week delay in the next scheduled injection before the initiation of Cycle 2 will be considered a DLT.
Measured: Cycle 1 (cycle length=28 days)
Phase 1: Number of Participants With Grade 3 or Higher TEAEs
AE Grades were evaluated as per National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE), version 4.03. Grade 3 scaled as severe or medically significant but not immediately life-threatening; Grade 4 scaled as life-threatening consequences; and Grade 5 scaled as death related to AE.
Measured: From the first dose of study drug through 30 days after the last dose (up to approximately 3.7 years)
Phase 1: Number of Participants With Serious TEAEs
TEAEs were any untoward medical occurrence (called an AE) that occurred after administration of the first dose of any study drug and through 30 days after the last dose of any study drug. A SAE is an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; or congenital anomaly; or a medically important event.
Measured: From the first dose of study drug through 30 days after the last dose (up to approximately 3.7 years)
Phase 1: Number of Participants With TEAEs Leading to Treatment Discontinuation
TEAEs leading to discontinuation were any untoward medical occurrence (called an AE) that occurred after administration of the first dose of any study drug and through 30 days after the last dose of any study drug leading to discontinuation of any of the study treatment when given in combination.
Measured: From the first dose of study drug through 30 days after the last dose (up to approximately 3.7 years)
Phase 1: Number of Participants With TEAEs Leading to Dose Modifications
TEAEs were any untoward medical occurrence (called an AE) that occurred after administration of the first dose of any study drug and through 30 days after the last dose of any study drug. Dose modification includes dose delayed, reduced, and drug discontinued permanently. Dose reduced includes scenarios where the dose was skipped, held, or missed. Dose modifications also refer to a modification of any drug in the study treatment when given in combination.
Measured: From the first dose of study drug through 30 days after the last dose (up to approximately 3.7 years)
Phase 2a: Overall Response Rate (ORR)
ORR is defined as the percentage of participants who achieved a partial response (PR) better during the study. PR is defined as >=50% reduction of serum M-protein and reduction in 24-hour urinary M-protein by >= 90% or to < 200 milligram per (mg/) 24 hours. If serum and urine M protein are not measurable, >= 50% decrease in difference between involved and uninvolved free light chain (FLC) levels is required in place of M protein criteria.
Measured: Up to approximately 3.7 years
Secondary outcomes (15)
Cmax: Maximum Observed Serum Concentration for TAK-079
Measured: Cycles 1 and 2: Day 1 pre-dose and at multiple time points (up to 168 hours) post-dose (cycle length=28 days)
Tmax: Time to Reach the Maximum Observed Serum Concentration (Cmax) for TAK-079
Measured: Cycles 1 and 2: Day 1 pre-dose and at multiple time points (up to 190.95 hours) post-dose (cycle length=28 days)
AUClast: Area Under the Serum Concentration-time Curve From Time 0 to the Time of the Last Quantifiable Concentration for TAK-079
Measured: Cycle 1 and 2: Day 1 pre-dose and at multiple time points (up to 168 hours) post-dose (cycle length=28 days)
Phase 1: Overall Response Rate (ORR)
ORR is defined as the percentage of participants who achieved a partial response (PR) or better during the study. PR is defined as >=50% reduction of serum M-protein and reduction in 24-hour urinary M-protein by >=90% or to <200 mg/24 hours. If the serum and urine M-protein were not measurable, a ≥50% decrease in the difference between involved and uninvolved FLC levels was required in place of the M-protein criteria. If serum and urine M-protein were not measurable, and serum FLC was also not measurable, ≥50% reduction in bone marrow plasma cells was required in place of M-protein, provided the baseline percentage was ≥30%. In addition to the above criteria, if present at baseline, ≥50% reduction in the size of soft tissue plasmacytomas was also required. Two consecutive assessments were needed; no known evidence of progressive or new bone lesions if radiographic studies were performed. Percentages are rounded off to whole number at the nearest decimal.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The purpose of this study is to assess the safety and tolerability, maximum tolerated dose (MTD)/recommended phase 2 dose (RP2D) of TAK-079 monotherapy and when combined with a backbone regimen of pomalidomide and dexamethasone (PomDex) in Phase 1, and to provide a preliminary evaluation of the clinical activity of TAK-079 monotherapy in Phase 2a in participants with r/r MM.
Detailed description
The drug being tested in this study is called TAK-079. TAK-079 is being tested to treat people who have relapsed and/or refractory multiple myeloma (RRMM). This study will assess the safety, tolerability, efficacy, pharmacokinetics, and immunogenicity of TAK-079 monotherapy and will provide a preliminary assessment of its activity against MM. The study is designed to consist of 2 phases: Phase 1 and Phase 2a.
The study could enroll approximately 100 participants. The study population of Phase 1 will consist of approximately 55 participants. Participants in Phase 1 will be assigned to TAK-079 and dose-escalation will range from 45 mg to 1800 mg.
The study population of Phase 2a will consist of approximately 48 participants. Dose for Phase 2a will be based upon review of the available safety, efficacy, pharmacokinetic, and pharmacodynamic data from the preceding cohorts of Phase 1.
This multi-center trial will be conducted in the United States. The overall time to participate in this study is 42 months (3.5 years). In Phase 1, participants who stop treatment for any other reason other than PD will continue to have progression-free survival (PFS) follow-up at the site every 4 weeks from the last dose of study drug up to 12 months or until PD, death, loss to follow-up, consent withdrawal or study termination. Participants will be followed 30 days after last dose of study drug or until the start of subsequent alternative anti-cancer therapy, whichever occurs first, for a follow up assessment.

Primary outcome
Phase 1: Number of Participants Reporting One or More Treatment-emergent Adverse Events (TEAEs)
Time frame: From the first dose of study drug through 30 days after the last dose (up to approximately 3.7 years)
TEAEs were any untoward medical occurrence (called an adverse event [AE]) that occurred after administration of the first dose of any study drug and through 30 days after the last dose of any study drug.
Phase 1: Number of Participants With Dose-limiting Toxicities (DLTs)
Time frame: Cycle 1 (cycle length=28 days)
DLTs were defined as any of the following events: Grade 4 laboratory abnormalities, except those events that were clearly due to extraneous causes; nonhematologic TEAEs of grade greater than or equal to (>=3) except grade 3 nausea/vomiting, fatigue lasting less than 72 hours, elevation of alanine aminotransferase (ALT) or aspartate aminotransferase (AST) that resolves to grade less than or equal to (<=)1 or baseline within 7 days, injection reaction (IR) that responds to symptomatic treatment; Hematologic TEAEs of National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) grade >=4, except grade >=3 hemolysis, grade 3 low platelet or higher count with clinically meaningful bleeding; and an incomplete recovery from treatment-related toxicity causing a greater than (>) 2-week delay in the next scheduled injection before the initiation of Cycle 2 will be considered a DLT.
Phase 1: Number of Participants With Grade 3 or Higher TEAEs
Time frame: From the first dose of study drug through 30 days after the last dose (up to approximately 3.7 years)
AE Grades were evaluated as per National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE), version 4.03. Grade 3 scaled as severe or medically significant but not immediately life-threatening; Grade 4 scaled as life-threatening consequences; and Grade 5 scaled as death related to AE.
Phase 1: Number of Participants With Serious TEAEs
Time frame: From the first dose of study drug through 30 days after the last dose (up to approximately 3.7 years)
TEAEs were any untoward medical occurrence (called an AE) that occurred after administration of the first dose of any study drug and through 30 days after the last dose of any study drug. A SAE is an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; or congenital anomaly; or a medically important event.
Phase 1: Number of Participants With TEAEs Leading to Treatment Discontinuation
Time frame: From the first dose of study drug through 30 days after the last dose (up to approximately 3.7 years)
TEAEs leading to discontinuation were any untoward medical occurrence (called an AE) that occurred after administration of the first dose of any study drug and through 30 days after the last dose of any study drug leading to discontinuation of any of the study treatment when given in combination.
Phase 1: Number of Participants With TEAEs Leading to Dose Modifications
Time frame: From the first dose of study drug through 30 days after the last dose (up to approximately 3.7 years)
TEAEs were any untoward medical occurrence (called an AE) that occurred after administration of the first dose of any study drug and through 30 days after the last dose of any study drug. Dose modification includes dose delayed, reduced, and drug discontinued permanently. Dose reduced includes scenarios where the dose was skipped, held, or missed. Dose modifications also refer to a modification of any drug in the study treatment when given in combination.
Phase 2a: Overall Response Rate (ORR)
Time frame: Up to approximately 3.7 years
ORR is defined as the percentage of participants who achieved a partial response (PR) better during the study. PR is defined as >=50% reduction of serum M-protein and reduction in 24-hour urinary M-protein by >= 90% or to < 200 milligram per (mg/) 24 hours. If serum and urine M protein are not measurable, >= 50% decrease in difference between involved and uninvolved free light chain (FLC) levels is required in place of M protein criteria.
