Testing the Use of Combination Therapy in Adult Patients With Newly Diagnosed Multiple Myeloma, the EQUATE Trial (EAA181)

in ,

Effective Quadruplet Utilization After Treatment Evaluation (EQUATE): A Randomized Phase 3 Trial for Newly Diagnosed Multiple Myeloma Not Intended for Early Autologous Transplantation

Overview

This phase III trial compares the combination of four drugs (daratumumab, bortezomib, lenalidomide and dexamethasone) to the use of a three drug combination (daratumumab, lenalidomide and dexamethasone). Bortezomib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Chemotherapy drugs, such as lenalidomide, 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. Daratumumab is a monoclonal antibody that may interfere with the ability of cancer cells to grow and spread. Anti-inflammatory drugs, such as dexamethasone lower the body’s immune response and are used with other drugs in the treatment of some types of cancer. Adding bortezomib to daratumumab, lenalidomide, and dexamethasone may be more effective in shrinking the cancer or preventing it from returning, compared to continuing on daratumumab, lenalidomide, and dexamethasone.

Females of childbearing potential must also agree to ongoing pregnancy testing while on protocol treatment. A female of childbearing potential is defined as any woman, regardless of sexual orientation or whether they have undergone tubal ligation, who meets the following criteria:
    • Has achieved menarche at some point,
    • Has not undergone a hysterectomy or bilateral oophorectomy; or
    • Has not been naturally postmenopausal (amenorrhea following cancer therapy does not rule out childbearing potential) for at least 24 consecutive months (i.e., has had menses at any time in the preceding 24 consecutive months)
  • STEP 1 – Women of childbearing potential must not expect to conceive children by using accepted and effective method(s) of contraception (for this protocol defined as the use of TWO acceptable methods of birth control, one highly effective method and one additional effective method AT THE SAME TIME for 1) at least 28 days before starting protocol treatment; 2) while participating in the study; 3) during dose interruptions; and 4) for at least 3 months days after the last dose of protocol treatment) OR by practicing true abstinence from sexual intercourse for the duration of their participation in the study (periodic abstinence [e.g., calendar, ovulation, symptothermal, post-ovulation methods] and withdrawal are not acceptable methods of contraception). Men must not expect to father children by practicing true abstinence from sexual intercourse for the duration of their participation in the study (periodic abstinence [e.g., calendar, ovulation, symptothermal, post-ovulation methods] and withdrawal are not acceptable methods of contraception) OR use a latex condom during sexual contact with a female of child bearing potential while participating in the study and for at least 3 months after the last dose of protocol treatment even if they have had a successful vasectomy. Men must also agree to abstain from donating sperm while on study treatment and for 3 months after the last dose of protocol treatment even if they have had a successful vasectomy.
