If low ANC is felt to be due to non-MM causes, such as myelodysplasia or other bone marrow disorders unrelated to MM, then subject should not be enrolled on the study.
  • Platelets ≥ 50 × 109/L if < 50% of bone marrow nucleated cells are plasma cells, and
  • ≥ 30 × 109/L if ≥ 50% of BM (Bone Marrow) nucleated cells are plasma cells.

FCBP must also agree to ongoing pregnancy testing during the entire duration of treatment and monthly for 5 months after the last dose of isatuximab. Men must agree to use a latex or synthetic condom during sexual contact with a FCBP even if they have had a vasectomy from the time of signing the informed consent form through 30 days after the last dose of lenalidomide and 5 months after the last dose of isatuximab. These same subjects must not donate sperm. All subjects must be counseled at a minimum of every 28 days about pregnancy precautions and risks of fetal exposure. All subjects enrolled into this trial, must be registered in and must comply with all requirements of the REVLIMID REMS program *A female of childbearing potential (FCBP) is a sexually mature female 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).

Who cannot join

  • Active infection requiring systemic antibiotics or other serious infection within 14 days prior to study treatment.
  • Subjects felt to not be candidates by treating physician for any systemic therapy due to excessive comorbidities, frailty, impaired performance status, or other severe limitations. Such limitations can be conceptualized generally as making subjects exceedingly high-risk for any systemic treatment for their MM. These limitations often stem from medical comorbidities unrelated to MM and they are hence unlikely to improve with MM therapy. The reasons for exclusion will be documented.
  • Any clinically significant, uncontrolled medical conditions that, in the Investigator's opinion, would expose excessive risk to the subject or may interfere with compliance or interpretation of the study results.
  • Light-chain (AL) amyloidosis. Subjects with secondary amyloidosis due to MM are eligible, if the amyloidosis is not felt to be a clinically significant issue (e.g., amyloid found incidentally on bone marrow core biopsy without evidence of amyloid-mediated organ compromise).
  • Myocardial infarction within 3 months prior to study treatment or has New York Heart Association (NYHA) Class III or IV heart failure, uncontrolled angina, severe uncontrolled ventricular arrhythmias, or electrocardiographic evidence of acute ischemia or active conduction system abnormalities.
  • Known allergy to any of the study medications, their analogues, or excipients in the various formulations of any agent.

  • Hypersensitivity or history of intolerance to steroids, mannitol, pregelatinized starch, sodium stearyl fumarate, histidine (as base and hydrochloride salt), arginine hydrochloride, poloxamer 188, sucrose or any of the other components of study therapy that are not amenable to premedication with steroids and H2 blockers or would prohibit further treatment with these agents.
  • Known gastrointestinal (GI) disease that could interfere with the oral absorption or tolerance of dexamethasone or lenalidomide including difficulty swallowing.
  • Serious medical or psychiatric illness likely to interfere with participation in this clinical study.
  • Patients with a history of prior or concurrent second primary malignancy whose natural history or treatment does not have the potential to interfere with the safety or efficacy assessment of the investigational treatment should generally be eligible.
  • Receiving other investigational agents less than 14 days or 5 half-lives of first dose of therapy on this protocol, whichever is longer.
  • Concurrent use of other anti-cancer agents or treatments with possible exception of agents with low likelihood of affecting outcome of this study, such as adjuvant hormonal therapy for remote history of breast cancer.
  • Known to be HIV+ or have active infection with hepatitis A, B, or C; or tuberculosis.
  • Chronic daily corticosteroids for other, non-MM-related medical conditions exceeding low-dose (e.g., prednisone ≥ 10 mg daily or equivalent).

About this study

Official title: Phase 2 Study of Isatuximab Plus Lenalidomide and Dexamethasone in Highly Toxicity-vulnerable Subjects With Newly Diagnosed Multiple Myeloma

This research study is investigating the safety and effectiveness of using combination of isatuximab, lenalidomide and dexamethasone for the treatment of newly diagnosed multiple myeloma (MM). The study team will use lower doses than is currently standard for these drugs. Lower doses will be used to avoid or possibly reduce any unwanted side effects commonly associated with these drugs. Using lower doses of the combination isatuximab, lenalidomide and dexamethasone, has not been approved by the Food and Drug Administration (FDA) for the treatment of newly diagnosed MM.

Read the detailed description

This study aims to determine the optimal treatment regimen for older and/or otherwise toxicity-vulnerable patients with newly diagnosed multiple myeloma (NDMM) who cannot receive approved standard therapy. As a result, this Phase II trial of isatuximab, lenalidomide, and dexamethasone (Isa-Rd) selectively enroll much older and/or otherwise highly toxicity-vulnerable participants. Furthermore, the safety and effectiveness of isatuximab when used in combination with lenalidomide and dexamethasone at lower doses will be evaluated. It is expected that using this combination at lower doses, may help patients achieve a better response while causing fewer or less severe side effects.

All participants on the trial will also be evaluated by Cancer and Aging Research Group Geriatric Assessments (CARG-GA) and patient-reported outcome (PRO) measures of quality of life (QOL). "Geriatric assessment" will be referred to as "global assessment" for study purposes, to reflect the fact that younger participants will likely participate in the study. Optional correlative blood samples will be collected to study biomarkers of aging and frailty with a focus on both the relation to isatuximab specifically, as well as treatment response and risk for intolerability.

Duration of Therapy:

The length of study participation will depend on the response to the treatment, and it may last approximately 2 years. Participants will receive isatuximab for two years, and then isatuximab will be discontinued. Dexamethasone administration will occur weekly for the first eight cycles. Lenalidomide will be continued as maintenance until disease progression or unacceptable toxicity.

In the absence of treatment delays due to adverse events, treatment should continue until:

  • Disease progression
  • Inter-current illness that prevents further administration of treatment
  • Treatment delay of more than 12 weeks.
  • Unacceptable adverse event(s)
  • Pregnancy
  • Subject decides to withdraw from study treatment, or
  • General or specific changes in the subject's condition render the subject unacceptable for further treatment in the judgment of the investigator.
  • Subject is lost to follow up

Duration of Follow Up:

All participants (including those withdrawn for AE (Adverse Event) will be followed after removal from study treatment until death or full subject withdrawal from the study for other reasons. Participants removed from study treatment for unacceptable AEs will be followed for resolution or stabilization of the adverse event(s).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Overall Response Rate (ORR)

    ORR, percentage of patients achieving a partial response or better per Revised Uniform Response Criteria by the International Myeloma Working Group (IMWG) criteria. Complete response (CR): Negative immunofixation of serum and urine, disappearance of soft tissue plasmacytomas, and <5% plasma cells in bone marrow (BM). Stringent complete response (sCR): CR plus normal free light chains (FLC) ratio and absence of clonal plasma cells in BM biopsy. Very good partial response (VGPR):-Serum and urine M-protein detectable by immunofixation but not on electrophoresis or ≥90% reduction in serum M component plus urine M component <100/24h. Partial response (PR) ≥50% reduction of serum M-protein \& reduction in 24-hour (24h) urinary M-protein by ≥90% or to <200 mg/24h and if present at baseline, a ≥ 50% reduction in the size soft tissue plasmacytomas

    Measured: From Day 1 of study treatment up to 60 months

Secondary outcomes (10)

  1. Treatment failure-free survival (TFFS) Time

    Treatment failure-free survival (TFFS): The length of time from therapy start until therapy discontinuation for any reason, including disease progression, toxicity, or death.

    Measured: From Day 1 of study treatment up to 60 months

  2. Progression-Free Survival (PFS)

    PFS is the length of time from start of study treatment until day of confirmed progression or death. The (IMWG) defines progression as any one or more: Increase of 25% from lowest response value in Serum M-protein (absolute increase (AI) ≥ 0.5 g/dL); Serum M-protein increase ≥ 1 g/dL, if lowest M component was ≥ 5 g/dL; or Urine M-protein Difference of involved \& uninvolved FLC (free light chain) levels (AI > 10 mg/dL) Bone marrow plasma cell percentage irrespective of baseline status (AI ≥ 10%) New lesion(s), ≥ 50% increase from nadir, or ≥ 50% increase in longest diameter of previous lesion >1 cm in short axis; ≥ 50% increase in circulating plasma cells if only measure of disease New or definite increase in size of existing soft tissue plasmacytomas or bone lesions; Decrease in hemoglobin of ≥ 2 g/dL not related to therapy; Rise in serum creatinine by ≥2 mg/dL; Hyperviscosity related to serum paraprotein

    Measured: From Day 1 of study treatment up to 60 months

  3. Maximum Depth of Response

    Maximum depth of response (from PR to CR, including sCR) at any time will be determined based on IMWG criteria. Descriptions of partial, complete, or stringent-complete type treatment responses are summarized in the primary outcome section.

    Measured: From Day 1 of study treatment up to 60 months

  4. Rate of achievement of bone marrow minimal residual disease (MRD) negativity

    MRD status is determined by next-generation sequencing with a minimum sensitivity of 1 × 10-5. MRD refers to myeloma cells that are present in the bone marrow after a clinical response has been measured while signs and symptoms of MM are reduced or disappeared.

    Measured: From Day 1 of study treatment up to 60 months

  5. Clinical Benefit Rate (minimal response (MR) + ORR)

    The clinical benefit rate is the percentage of participants achieving overall response or minimal response. Description of overall response as defined as the percentage of subjects achieving a partial response or better (≥ PR) to study therapy at any time. Minimal response (MR) is ≥ 25% but ≤ 49% reduction of serum M-protein and reduction in 24-h urine M-protein by 50-89%. In addition to the above listed criteria, if present at baseline, a ≥ 50% reduction in the size (SPD) of soft tissue plasmacytomas is also required.

    Measured: From Day 1 of study treatment up to 60 months

  6. Time to Response

    Time to response is the length of time from start of study treatment until documentation of confirmed partial response (PR) or better based on IMWG criteria. Response description is given in the primary outcome section.

    Measured: From Day 1 of study treatment up to 60 months

  7. Duration of Response

    Duration of response is the length of time from achievement of PR or better until myeloma progression per IMWG criteria. PR description is given in the primary outcome section.

    Measured: From Day 1 of study treatment up to 60 months

  8. Time to Next Treatment

    Time to next treatment is the length of time time from start of study treatment to next MM treatment or death from any cause.

    Measured: From Day 1 of study treatment up to 60 months

  9. Overall Survival

    Overall Survival is the length of time from start of study treatment to death from any cause.

    Measured: From Day 1 of study treatment up to 60 months

  10. Toxicity Rate

    Toxicity rate is percentage of participants who experience treatment related Adverse Events (AE) as evaluated by National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE) criteria version 5.0. NCI-CTCAE is a descriptive terminology utilized for AE reporting. A grading (severity) scale is provided for each AE term. Grade 1 Mild; asymptomatic or mild symptoms; clinical or diagnostic observations only; intervention not indicated. Grade 2 Moderate; minimal, local or noninvasive intervention indicated; limiting age-appropriate instrumental Activities of Daily Living (ADL). Grade 3 Severe or medically significant but not immediately life-threatening; hospitalization or prolongation of hospitalization indicated; disabling; limiting self care ADL. Grade 4 Life-threatening consequences; urgent intervention indicated. Grade 5 Death related to AE.

    Measured: From Day 1 of study treatment up to 60 months
