Isatuximab, Lenalidomide, Bortezomib, and Dexamethasone in NDMM

Phase 2

Recruiting

• Conditions: Multiple Myeloma; Autologous Stem Cell Transplant; Newly Diagnosed Multiple Myeloma (NDMM)
• Interventions: Drug: Isatuximab; Drug: Lenalidomide; Drug: Bortezomib Injection; Drug: Dexamethasone

• Registration Number: NCT04653246
• Lead Sponsor: Jacob Laubach, MD

Brief Summary

This research is testing whether the investigational drug isatuximab is safe and effective when used in combination with standard agents for the treatment of newly diagnosed multiple myeloma.

Detailed Description

This is a multi-center, single-arm, open-label, Phase 2 study in patients with newly diagnosed multiple myeloma (NDMM) eligible for high dose therapy (HDT) and autologous stem cell transplant (ASCT).

In this research study, investigators are evaluating whether isatuximab is safe and effective in participants with newly diagnosed multiple myeloma when given in combination with lenalidomide, bortezomib, and dexamethsone.

* This research study involves administration of a four-drug chemotherapy regimen that combines the Investigational drug isatuximab with a standard chemotherapy regimen comprised of lenalidomide, bortezomib, and dexamethasone.

* This 4-drug regimen is not considered standard of the treatment of newly diagnosed multiple myeloma.

This research study is a Phase II clinical trial. Phase II clinical trials test the safety and effectiveness of an investigational drug or combination of drugs to learn whether the drug works in treating a specific disease. "Investigational" means that the drug is being studied.

The U.S. Food and Drug Administration (FDA) has approved lenalidomide, bortezomib, and dexamethasone as treatment options for this disease but the combination of these agents with isatuximab hasn't been approved.

• Central nervous system involvement.

• Any medical or psychiatric illness that in the Investigator's opinion, would impose excessive risk to the patient or would adversely affect his/her participating in this study.

• Concurrent uncontrolled cardiovascular conditions, including uncontrolled hypertension, uncontrolled cardiac arrhythmias, symptomatic congestive heart failure, unstable angina, Grade 3 thromboembolic event or myocardial infarction within the past 6 months.

• Prior major surgical procedure or radiation therapy within 4 weeks of initiation of therapy (this does not include limited course of radiation used for management of bone pain within 7 days of initiation of therapy).

• Daily requirement for corticosteroids (equivalent to > 10 mg/day prednisone for more than 7 days (except for inhalation corticosteroids).

• Concurrent symptomatic amyloidosis or plasma cell leukemia

• POEMS syndrome (plasma cell dyscrasia with polyneuropathy, organomegaly, endocrinopathy, monoclonal protein and skin changes)

• Known active infection requiring parenteral or oral anti-infective treatment within 14 days of start of therapy.

• Active hepatitis B or hepatitis C viral infection

• Pregnant or breastfeeding female or female who intends to become pregnant during the participation in the study. Females of childbearing potential (FCBP) unwilling to prevent pregnancy by the use of 2 reliable methods of contraception for ≥4 weeks before the start of study treatment, during treatment (including dose interruptions), and up to 3 months following the last dose of study treatment and/or who are unwilling or unable to be tested for pregnancy before study treatment initiation (2 negative tests), weekly during 1st month of treatment and then prior each treatment cycle administration or every 2 weeks in case or irregular menstrual cycles up to 3 months following the last dose of study treatment.

• Male participants who disagree to practice true abstinence or disagree to use a condom during sexual contact with a pregnant female or a FCBP while participating in the study, during dose interruptions and at least 3 months following study treatment discontinuation, even if has undergone a successful vasectomy.

  • Note 1: a FCBP is a female who: 1) has achieved menarche at some time point, 2) has not undergone a hysterectomy or bilateral oophorectomy or 3) has not been naturally postmenopausal (amenorrhea following cancer therapy does not rule out childbearing potential) for at least 24 consecutive months (ie, has had menses at any time in the preceding 24 consecutive months).
  • Note 2: True abstinence is acceptable when this is in line with the preferred and usual lifestyle of the patient. Periodic abstinence (eg, calendar, ovulation, symptothermal, post-ovulation methods) and withdrawal are not acceptable methods of contraception.

• Receiving any other investigational agents

• Inability to tolerate thromboprophylaxis

• Hypersensitivity (or contraindication) to dexamethasone, sucrose histidine (as base and hydrochloride salt), boron, mannitol, and polysorbate 80, or to any of the components of the study therapy

• Hypersensitivity to steroids or H2 blockers that would prohibit further treatment with these agents.
