  • * Documentation of disease: Diagnosis of multiple myeloma and have relapsed or refractory disease according to the IMWG criteria where:
  • * Progression of myeloma is defined by IMWG criteria as recurrence of disease after prior response, indicated as any of the following:
  • • ≥ 25% increase in M-protein (must be at least 0.5g/dl above nadir from last treatment regimen).
  • • 25% difference between involved and uninvolved serum free light chains from its nadir or
  • • The development of new plasmacytomas or hypercalcemia.
  • • Refractory myeloma as defined by IMWG criteria as disease which become non-responsive or progresses on therapy or within 60 days of last treatment in patients who had achieved a minimal response or better on prior therapy.
  • * Measurable disease defined by IMWG criteria as:
  • • Serum M-protein ≥ 0.5 g/dL.
  • • Urine monoclonal protein ≥ 200 mg/24h.
  • • Serum free light chains (FLC) assay: Involved FLC level ≥ 10 mg/dl (≥ 100 mg/l) and serum free light chain ratio is abnormal.

  • • Eastern Cooperative Oncology Group (ECOG) performance status ≤ 2.
  • • Absolute neutrophil count (ANC) ≥ 1,000/mm\^3.
  • • Platelet count ≥ 75,000/mm\^3 (or ≥ 50,000/mm\^3 in Phase II if bone marrow (BM) plasma cells \> 50%).
  • • Calculated (Calc.) creatinine clearance ≥ 30 mL/min using Cockcroft-Gault equation.
  • • Spot urine (albumin/creatinine ratios) \< 500 mg/g (56 mg/mmol) OR urine dipstick ≥ 1+ if confirmed.
  • • Total bilirubin ≤ 2 mg/dL.
  • • Aspartate aminotransferase (AST)/alanine transaminase (ALT) ≤ 2.5 x upper limit of normal (ULN).
  • * Not pregnant and not nursing, because this study involves an investigational agent whose genotoxic, mutagenic and teratogenic effect on the developing fetus and newborn are unknown. FCBP (female of childbearing potential) is a female who: 1) has achieved menarche (first menstrual cycle) at some point, 2) has not undergone a hysterectomy (the surgical removal of the uterus) or bilateral oophorectomy (the surgical removal of both ovaries) 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 during the preceding 24 consecutive months). Women of childbearing potential (WOCBP):
  • • Must use a contraceptive method that is highly effective (with a failure rate of \< 1% per year), preferably with low user dependency during the intervention period and for at least 4 months after the last dose of study intervention and agrees not to donate eggs (ova, oocytes) for the purpose of reproduction during this period. The investigator should evaluate the effectiveness of the contraceptive method in relationship to the first dose of study intervention.
  • • The effects of iberdomide on the developing human fetus are unknown. Immunodulatory derivative (IMiD) agents as well as other therapeutic agents used in this trial are known to be teratogenic. Females of child-bearing potential must have a negative serum or urine pregnancy test with a sensitivity of at least 25 mIU/mL within 10-14 days prior to, and again within 24 hours of starting iberdomide, and must either commit to continued abstinence from heterosexual intercourse or begin two acceptable methods of birth control, one highly effective method and one additional effective method at the same time, at least 28 days before she starts taking iberdomide. Examples of highly effective methods are intrauterine device, hormonal contraceptives, tubal ligation, or partner's vasectomy. Examples of barrier method are male condom, diaphragm, or cervical cap. FCBP must also agree to ongoing pregnancy testing. Men must agree to use a latex condom during sexual contact with a FCBP even if they have had a successful vasectomy. All patients must be counseled at a minimum of every 28 days about pregnancy precautions and risk of fetal exposure.
  • • Should a woman become pregnant or suspect she is pregnant while she or her partner are participating in this study, she should inform her treating physician immediately. FCBP must use adequate contraception for at least 4 months after discontinuation from study. Because of the potential for serious adverse reactions in a breastfed child, women are advised not to breastfeed during treatment and for at least 3 months after the last dose.
  • * The investigator is responsible for review of medical history, menstrual history, and recent sexual activity to decrease the risk for inclusion of a woman with a nearly undetected pregnancy. Nonchildbearing potential is defined as follows (by other than medical reasons):
  • • ≥ 45 years of age and has not had menses for \> 1 year
  • • Patients who have been amenorrhoeic for \< 2 years without history of a hysterectomy and oophorectomy must have a follicle stimulating hormone value in the postmenopausal range upon screening evaluation
  • • Post-hysterectomy, post-bilateral oophorectomy, or post-tubal ligation. Documented hysterectomy or oophorectomy must be confirmed with medical records of the actual procedure or confirmed by an ultrasound. Tubal ligation must be confirmed with medical records of the actual procedure.
  • • Male patients must agree to use an adequate method of contraception for the duration of the study and for 6 months afterwards.
  • * Male participants: contraceptive use should be consistent with local regulations regarding the methods of contraception for those participating in clinical studies: Male participants are eligible to participate if they agree to the following during the intervention period and for 6 months after the last dose of study treatment 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).
  • • Archival tissue must be available for submission for the mandatory correlative studies.
  • • 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.
