• PRE-REGISTRATION: Histological confirmation of relapsed and/or refractory Waldenstrom macroglobulinemia, with known prior exposure to a Bruton tyrosine kinase (BTK) inhibitor unless medically contraindicated. Note: although not preferred, archival bone marrow tumor tissue that was collected within 12 weeks prior to screening and without intervening anti- BCMA treatment may be used if the patient is unwilling to provide a fresh pretreatment marrow biopsy

If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required

• PRE-REGISTRATION: Willing to follow strict birth control measures as suggested by the study

• PRE-REGISTRATION: Female participants: Female participant is eligible to participate if she is not pregnant or breast feeding, and at least one of the following conditions applies:

  • Is not a woman of childbearing potential (WOCBP) OR

  • Due to the risk for embryo-fetal toxicity and prescribed under a pregnancy prevention/controlled distribution program, WOCBP participants will be eligible if they commit to either:

    • Abstain continuously from heterosexual sexual intercourse as their preferred and usual lifestyle (abstinent on a long term and persistent basis) and agree to remain abstinent OR

    • To use birth control as follows:

      • Two methods of reliable birth control (one method that is highly effective and one additional effective (barrier) method), beginning 4 weeks prior to initiating treatment with lenalidomide, during therapy, during dose interruptions and continuing for 4 weeks following discontinuation of lenalidomide treatment

• PRE-REGISTRATION: Male patients: Male participants are eligible to participate if they agree to the following from the time of first dose of study treatment until 28-days after the last dose of lenalidomide, to allow for clearance of any altered sperm:

  • Refrain from donating sperm PLUS either:

    • Be abstinent from heterosexual intercourse as their preferred and usual lifestyle (abstinent on a long term and persistent basis) and agree to remain abstinent. OR

    • Must agree to use contraception/barrier as detailed below:

      • Agree to use a male condom, even if they have undergone a successful vasectomy, and female partner to use an additional highly effective contraceptive method with a failure rate of < 1% per year as when having sexual intercourse with a woman of childbearing potential (including pregnant females)

• Note: Subjects of childbearing potential must practice at least one of the specified method of birth control with partner(s) initiated prior to first dose of study drug administration to 90 days after the last dose of study drug. These methods include the following:

  • A barrier method of contraception (including male and female condoms with or without spermicide) plus one of the following hormonal contraceptives:

    • Combined (estrogen and progestogen containing) hormonal contraception associated with the inhibition of ovulation
    • Oral, intravaginal or transdermal
    • Progestogen-only hormonal contraception associated with the inhibition of ovulation
    • Oral, injectable, implantable
    • An intrauterine device (IUD)
    • Intrauterine hormone-releasing system (IUS)

  • Bilateral tubal occlusion

  • Vasectomized partner

  • Sexual abstinence (defined as refraining from heterosexual intercourse during the entire period of risk associated with the study treatment, starting the day prior to first dose of study drug, for the duration of the study, and for 90 days after the last dose of study drug). Total sexual abstinence should only be used as a contraceptive method if it is in line with the subjects' usual and preferred lifestyle. Periodic abstinence (e.g., calendar, ovulation, symptothermal, post-ovulation methods), declaration of abstinence for the duration of exposure to the investigational medicinal product (IMP), and withdrawal are not acceptable methods of contraception.
