Dexamethasone, Carfilzomib, & Nivolumab With Pelareorep for Relapsed/Refractory Multiple Myeloma

PD1 Blockade and Oncolytic Virus in Relapsed Multiple Myeloma

This phase I trial studies the side effects and best dose of wild-type reovirus (pelareorep) when given together with dexamethasone, carfilzomib, and nivolumab in treating patients with multiple myeloma that has come back (relapsed). Drugs used in chemotherapy, such as dexamethasone, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Carfilzomib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Immunotherapy with monoclonal antibodies, such as nivolumab, may help the body's immune system attack the cancer and may interfere with the ability of tumor cells to grow and spread. A virus, called pelareorep, which has been changed in a certain way, may be able to kill tumor cells without damaging normal cells. Giving dexamethasone, carfilzomib, and nivolumab with pelareorep may work better in treating patients with multiple myeloma.

Study Overview

• Status: Completed
• Conditions: Recurrent Plasma Cell Myeloma
• Intervention / Treatment: Biological: Nivolumab; Drug: Carfilzomib; Drug: Dexamethasone; Biological: Pelareorep

Detailed Description

PRIMARY OBJECTIVES:

I. Identify maximum tolerated dose of pelareorep in combination with other antineoplastic agents.

II. Identify whether the combination of carfilzomib and nivolumab lead to a safety profile different than what has been reported with either agent independently.

SECONDARY OBJECTIVES:

I. Assess the relative roles of immune-mediated and direct cytotoxic myeloma cell killing.

II. Understand the clinical benefit of nivolumab in programmed death-ligand 1 (PD-L1) positive multiple myeloma (MM) cells.

OUTLINE: This is a dose-escalation study of pelareorep. Patients are assigned to 1 of 3 arms.

ARM 1: Patients receive dexamethasone intravenously (IV) on days 1, 2, 8, 9, 15, and 16, carfilzomib IV over 30 minutes on days 1, 2, 8, 9, 15, and 16, and nivolumab IV over 30 minutes on days 1 and 15. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.

ARM 2: Patients receive dexamethasone IV on days 1, 2, 8, 9, 15, and 16, pelareorep IV on days 1, 2, 8, 9, 15, and 16, carfilzomib IV over 30 minutes on days 1, 2, 8, 9, 15, and 16, and nivolumab IV over 30 minutes on days 1 and 15. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.

ARM 3 (expansion cohort): Patients receive dexamethasone IV on days 1, 2, 8, 9, 15, and 16, pelareorep IV on days 1, 2, 8, 9, 15, and 16, carfilzomib IV over 30 minutes on days 1, 2, 8, 9, 15, and 16, and nivolumab IV over 30 minutes on days 1 and 15. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up for a minimum of 4 weeks once off treatment or at least 100 days after the last nivolumab dose, then every 6 months after.

• Females of childbearing potential (FCBP) must have a negative serum or urine pregnancy test prior to starting therapy. The effects of pelareorep and nivolumab on the developing human fetus are unknown. For this reason, women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation. Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately. Female of childbearing potential (FCBP) is a sexually mature woman who: 1) has not undergone a hysterectomy or bilateral oophorectomy; or 2) has not been naturally postmenopausal for at least 24 consecutive months (i.e., has had menses at any time in the preceding 24 consecutive months)

• The patient must be willing to comply with fertility requirements as below:

  • Male patients must agree to use an adequate method of contraception for the duration of the study and for 7 months afterwards
  • Female patients must be either postmenopausal, free from menses ≥ 2 years, surgically sterilized, willing to use two adequate barrier methods of contraception to prevent pregnancy, or agree to abstain from heterosexual activity starting with screening and for 5 months after last treatment in all patients
  • Patients must agree not to donate blood, sperm/ova while taking protocol therapy and for at least 7 months after stopping treatment (for males) and 5 months after stopping treatment (for females)
• Ability to understand and the willingness to sign a written informed consent document
• Patients with a prior or concurrent malignancy whose natural history or treatment does not have the potential to interfere with the safety or efficacy assessment of the investigational regimen are eligible for this trial

Exclusion Criteria:

• Known human immunodeficiency virus (HIV) infection or active hepatitis B or C due to risk of viral infectivity of pelareorep
• Known pulmonary hypertension
• Patients who are receiving any other anti-myeloma investigational agents
• Polyneuropathy, organomegaly, endocrinopathy, monoclonal protein, skin changes (POEMS) syndrome, primary amyloidosis (AL amyloidosis), and Waldenstrom macroglobulinemia
• Patients who have had anti-myeloma treatment, radiotherapy, plasmapheresis, or major surgery (as defined by the investigator) within 2 weeks prior to cycle 1 day 1 of the study. Patients may be receiving concomitant therapy with bisphosphonates and low dose corticosteroids (e.g., prednisone up to but no more than 10 mg by mouth daily or its equivalent) for symptom management and comorbid conditions
• Uncontrolled illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, myocardial infarction in the preceding 6 months, or psychiatric illness/social situations that would limit compliance with study requirements
• Pregnant women are excluded from this study because protocol therapy has the potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk for adverse events in nursing infants secondary to protocol treatment of the mother, breastfeeding should be discontinued
