About the Trial

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

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.

Detailed Info

Brief Summary

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.

About Relapsed or Refractory Multiple Myeloma (RRMM)

About Relapsed or Refractory Multiple Myeloma (RRMM)

Multiple myeloma (MM) is a cancer of plasma cells. Plasma cells are found mainly in the bone marrow and they make the antibodies (also known as immunoglobulins) that help the body fight and kill germs. MM is a cancer that develops when plasma cells grow out of control.

Relapsed (or recurrent) multiple myeloma is the term for when cancer returns after treatment or after a period of remission. Most multiple myeloma patients will relapse at some point as this cancer is still incurable. Refractory multiple myeloma refers to when the cancer does not respond to therapy. In some cases, the cancer will respond to initial treatment, but not to treatments following relapse.
