Clinical Trial Summary

This phase I trial tests the side effects and best dose of TGFbi natural killer (NK) cells (TiNK) when given together with isatuximab for the treatment of patients with multiple myeloma that has come back after a period of improvement (relapsed) or that has not responded to treatment (refractory). NK cells are a type of white blood cell that are known to spontaneously attack cancer cells. TiNK are NK cells made in a laboratory to have a higher response to tumor cells. A monoclonal antibody is a type of protein that can bind to certain targets in the body, such as molecules that cause the body to make an immune response (antigens). Immunotherapy with monoclonal antibodies, such as isatuximab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Patients also receive standard treatment (cyclophosphamide and dexamethasone) on this trial. Cyclophosphamide is in a class of medications called alkylating agents. It works by damaging the cell's DNA and may kill cancer cells. It may also lower the body's immune response. Dexamethasone is in a class of medications called corticosteroids. It is used to reduce inflammation and lower the body's immune response to help lessen the side effects of chemotherapy drugs. Giving TiNK and isatuximab with standard treatment may be a safe and effective treatment for relapsed or refractory multiple myeloma.

Description:

PRIMARY OBJECTIVE:

I. To evaluate the safety and tolerability of transforming growth factor beta imprinted natural killer cells (TiNK) and isatuximab in patients with multiple myeloma (MM) relapsed or refractory (R/R) to BCMA-targeting therapy.

SECONDARY OBJECTIVES:

I. To evaluate the objective response rate (ORR) by International Myeloma Working Group (IMWG) criteria of TiNK and isatuximab in patients with MM R/R to BCMA-targeting therapy.

II. To determine the time to response (TTR), time to next therapy (TTNT), the duration of response (DOR), progression free survival (PFS), and overall survival (OS) at 1 year.

III. To determine correlatives of outcomes. IV. To assess quality of life (QOL) with therapy.

OUTLINE: This is a dose-escalation study of TiNK followed by a dose-expansion study.

Patients receive cyclophosphamide intravenously (IV) on day 1, dexamethasone orally (PO) on days 1-4, TiNK IV on day 8, and isatuximab IV on days 8 and 15 of each cycle. Treatment repeats every 28 days for up to 6 cycles in the absence of disease progression or unacceptable toxicity. Patients undergo bone marrow aspiration and biopsy during screening and on study, as well as optionally during follow up. Patients undergo echocardiography (ECHO) during screening and blood sample collection throughout the study.

After completion of study treatment, patients are followed up at 30 days, 60 days. Patients who discontinue study treatment for reasons other than progressive disease follow up every 12 weeks for up to 2 years.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Incidence and severity of adverse events (AE)	Will use the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version (v) 5.0 for AE collection. The maximum grade for each type of toxicity will be recorded for each patient, and frequency tables will be reviewed to determine toxicity patterns. The incidence of severe (grade 3+) adverse events or toxicities will be described. We will also assess tolerability of the regimen through assessing the number of patients who required dose modifications and/or dose delays. In addition, we will capture the proportion of patients who go off treatment due to adverse reactions.	Up to 60 days after completion of study treatment
Secondary	Overall response rate (ORR)	Will be defined as the total number of subjects whose best response is partial response (PR) or better divided by the number of patients. Will be reported overall with 95% binomial exact confidence intervals. Comparison of ORR among patient subgroups will be conducted using Fisher exact test.	Up to 2 years after completion of study treatment
Secondary	Time to response	Cumulative incidence rates will be calculated and compared using Gray's test accounting for competing risks.	From start of treatment until measurement criteria are first met for PR, very good partial response (VGPR), or complete response (CR), assessed up to 2 years after completion of study treatment
Secondary	Time to next therapy	Cumulative incidence rates will be calculated and compared using Gray's test accounting for competing risks.	From start of treatment until initiation of the next line of therapy, assessed up to 2 years after completion of study treatment
Secondary	Duration of response	Will be computed for subjects whose best response is either PR, VGPR, or CR. Will be analyzed using the Kaplan-Meier method.	From the time measurement criteria are first met for PR or better (whichever status is recorded first) until the first date of progressive disease or death, assessed up to 2 years after completion of study
Secondary	Progression free survival	Will be analyzed using the Kaplan-Meier method.	From start of treatment until disease progression or death, at 1 year
Secondary	Overall survival	Will be analyzed using the Kaplan-Meier method.	From start of treatment to the date of his or her death, at 1 year
Secondary	Change in quality of life (QOL) using PROMIS G10	Using the Patient-Reported Outcomes Measurement Information System Global 10 Quality of Life Survey (PROMIS G10 QOL) A repeated measures linear mixed model will be fit to all QOL scores. The response options are presented as 5-point (and single 11-point for pain rating scales). The results of the questions are used to calculate two summary scores.	Baseline up to 60 days after completion of study treatment
Secondary	Change in quality of life (QOL) using EORTC QLQ-MY20	Using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire - Multiple Myeloma20 (EORTC QLQ - MY20). A repeated measures linear mixed model will be fit to all QOL scores. This incorporates four multi-item scales to assess disease symptoms, side effects of treatment, future perspective and body image. All of the scales and single-item measures range in score from 0 to 100. A high score for the symptom scales represents a high level of symptomatology or problems, whereas a high score for the functional scale represents a high level of functioning.	Baseline up to 60 days after completion of study treatment
