Brief summary

The main aim of the trial is to learn how well adults with refractory lupus nephritis (LN) or refractory systemic sclerosis (SSc) tolerate TAK-007 and to check for side effects (adverse events). Other aims are to learn how effective treatment with TAK-007 is in adults with refractory LN or refractory SSc, what effects TAK-007 has on the human body, and whether participants will produce antibodies against TAK-007.

Detailed description

The drug being tested in this trial is called TAK-007. TAK-007 is being tested to treat people with refractory LN or refractory SSc. This trial will look at the safety and tolerability of TAK-007. The trial will enroll approximately 26 participants. Participants will receive a single dose or multiple doses of TAK-007, which is an anti-CD19 chimeric antigen receptor natural killer cell (CD19 CAR-NK) therapy. Participants with refractory LN will be treated with 3 days of intravenous (IV) lymphodepleting chemotherapy (LDC) and then after a gap of at least 2 days, a single IV dose of TAK-007 on Day 1. For participants with refractory SSc the trial has 2 parts. In Part 1, participants with refractory SSc will be treated with 3 days of IV LDC and then after a gap of at least 2 days, a single IV dose (Part 1a - single dose) or three IV doses (Part 1b - multiple doses) of TAK-007. Based on the data of Part 1, Part 2 (expansion) may be initiated in participants with refractory SSc to further evaluate the impact of LDC followed by single dose or multiple doses of TAK-007. This multi-center trial will be conducted in the United States. The overall time to participate in this study is approximately 24 months.
