A Study of TAK-169 in Participants With Relapsed or Refractory Multiple Myeloma

NCT04017130

Description:

Multiple Myeloma is a type of blood cancer in cells made in the bone marrow. Relapsed means the previous cancer treatment worked for a while but stopped working, over time. Refractory means people did not respond to previous cancer treatment. TAK-169 is a medicine that binds to the surface of multiple myeloma cells called CD38 cells. It delivers a dose of chemotherapy to the CD38 cells. This study is in 2 parts. The main aims of Part 1 of the study are to check how much TAK-169 a person can receive without getting side effects from it, and to work out the best dose of TAK-169 to give people to treat their cancer. The main aim of Part 2 of the study is to learn if the condition of people with multiple myeloma improves after treatment with TAK-169. Another aim is to check for side effects from TAK-169. In Part 1, at the first visit, the study doctor will check who can take part. Participants who can take part will receive TAK-169 slowly through the vein (infusion). This will happen once a week during a 28-day cycle. Different small groups of participants will receive lower to higher doses of TAK-169. The study doctors will check for side effects after each dose of TAK 169. In this way, researchers can work out the best dose of TAK-169 to give participants in Part 2 of the study. Each participant will stay in the clinic for at least 24 hours after they have received their first infusion of TAK-169. Once the best dose has been worked out, different small groups of participants will receive lower to higher doses of TAK-169 every 2 weeks, starting at the best dose. In Part 2, at the first visit, the study doctor will check who can take part, as only some participants with multiple myeloma can take part. Participants who previously did not respond to daratumumab or it worked for a while but stopped working, over time will have 1 of 2 treatments. - Some will receive TAK-169 once a week. - Others will receive TAK-169 every 2 weeks. Participants who have never previously received other medicines that bind to the multiple myeloma CD38 cells can also take part. They will receive TAK-169 once a week. All participants in Part 2 will receive the best dose of TAK-169 worked out in Part 1. In both parts of the study, participants can receive TAK-169 for up to 1 year. They could receive TAK-169 for longer than 1 year if their multiple myeloma continues to improve or remains stable during treatment. After treatment has finished, participants will visit the clinic for a check-up every 12 weeks.

Purpose

Multiple Myeloma is a type of blood cancer in cells made in the bone marrow. Relapsed means the previous cancer treatment worked for a while but stopped working, over time. Refractory means people did not respond to previous cancer treatment. TAK-169 is a medicine that binds to the surface of multiple myeloma cells called CD38 cells.

Detailed Description

      The drug being tested in this study is called TAK-169. The study will evaluate the safety,
      tolerability, preliminary efficacy, PK, pharmacodynamics, and immunogenicity of TAK-169
      monotherapy in participants with RRMM.

      The study will be conducted in 2 phases: Dose Escalation Phase (Part 1) and an Expansion
      Phase (Part 2). The study will enroll approximately 81 to 102 participants (39 to 60
      participants in Part 1 and approximately 54 participants in Part 2).

      In the Dose Escalation Phase (Part 1), the starting dose level will be 50 microgram/kilogram
      (mcg/kg), once weekly. On the basis of investigator and sponsor review of available safety,
      PK, pharmacodynamic, and efficacy data from Cohort 1, the dose will be escalated in the
      subsequent cohorts to 100, 200, 335, 500, and 665 mcg/kg, once weekly. A separate dose
      escalation may also occur in which TAK-169 will be administered once every 2 weeks.

      In the Expansion Phase (Part 2), the study will evaluate two types of RRMM cohorts:
      Daratumumab-relapsed or Refractory (RR) Cohorts (once weekly and once every 2 weeks TAK-169
      administration) and an Anti-CD38 Therapy Naive Cohort (once weekly TAK-169 administration).
      The starting dose for each expansion cohort will be the MTD/RP2D (once weekly and once every
      2 weeks) determined in Part 1 after review of the available safety, efficacy, PK, and
      pharmacodynamic data from the dose escalation phase of the study.

      This multi-center trial will be conducted in the United States. The overall duration of the
      study is 34 months. Participants will be followed up for 30 days after the last dose of study
      drug for a follow-up assessment.

Measure:Part 1 and Part 2: Number of Participants With Anti-drug Antibodies Following Administration of TAK-169
Time Frame:Up to 12 months
Safety Issue:
Description:
Measure:Part 2: Number of Participants With DLTs and Other TEAEs Including Dose Modifications, Treatment Discontinuation, and Vital signs
Time Frame:Up to 12 months
Safety Issue:
Description:DLTs is defined as any of the events that are considered by the investigator to be at least possibly related to therapy with the study medication. Toxicity will be evaluated according to NCI CTCAE 5.0.
Measure:Part 2: Overall Survival (OS)
Time Frame:From date of the dose administration until death due to any cause (up to 12 months)
Safety Issue:
Description:OS is defined as time from date of the dose administration until death due to any cause.
Measure:Part 2: Time to Response (TTR)
Time Frame:From the date of the first dose of the study treatment to the date of the first documentation of response (up to 12 months)
Safety Issue:
Description:Time from the date of the first dose of the study treatment to the date of the first documentation of response (PR or better). PR is >=50% reduction of serum M protein and reduction in 24-hour urinary M protein by >=90% or to <200 mg/24 hour. If serum and urine M protein are not measurable, >=50% decrease in difference between involved and uninvolved FLC levels is required in place of M protein criteria. If serum and urine M protein and serum FLC assay are not measurable, >=50% reduction in bone marrow plasma cells is required in place of M protein, provided baseline percentage was >=30%. In addition, if present at baseline, >=50% reduction in size of soft tissue plasma cytomas is required. Two consecutive assessments are needed; no known evidence of progressive or new bone lesions if radiographic studies were performed.
Measure:Part 2: Percentage of Participants Who Achieved Complete Response (CR) or Very Good Partial Response (VGPR)
Time Frame:Up to 12 months
Safety Issue:
Description:CR or VGPR is defined by IMWG criteria. CR is defined as Negative immunofixation of serum and urine, disappearance of any soft tissue plasmacytomas, and <5% plasma cells in bone marrow; in participants for whom only measurable disease is by serum FLC level, normal FLC ratio of 0.26 to 1.65 in addition to CR criteria is required; Two consecutive assessments are needed. VGPR is defined as serum and urine M component detectable by immunofixation but not on electrophoresis or >=90% reduction in serum M component plus urine M component <100 mg/24 h; in participants for whom only measurable disease is by serum FLC level, >90% decrease in difference between involved and uninvolved FLC levels, in addition to VGPR criteria, is required; Two consecutive assessments are needed.
