Do not use lenalidomide during pregnancy. Lenalidomide, a thalidomide analogue, caused limb abnormalities in a developmental monkey study. Thalidomide is a known human teratogen that causes severe, life-threatening human birth defects. If lenalidomide is used during pregnancy, it may cause birth defects or embryo-fetal death. In females of reproductive potential, obtain 2 negative pregnancy tests before starting lenalidomide treatment. Females of reproductive potential must use 2 forms of contraception or continuously abstain from heterosexual sex during and for 4 weeks after lenalidomide treatment. To avoid embryo-fetal exposure to lenalidomide, it is only available under a restricted distribution program called Lenalidomide REMS program.
Information about the Lenalidomide REMS program is available at http://www.lenalidomiderems.com or by calling the REMS Call Center at 1-888-423-5436.
Lenalidomide can cause significant neutropenia and thrombocytopenia. Eighty percent of patients with deletion 5q myelodysplastic syndromes had to have a dose delay/reduction during the major study. Thirty-four percent of patients had to have a second dose delay/reduction. Grade 3 or 4 hematologic toxicity was seen in 80% of patients enrolled in the study. Patients on therapy for deletion 5q myelodysplastic syndromes should have their complete blood cell counts monitored weekly for the first 8 weeks of therapy and at least monthly thereafter. Patients may require dose interruption and/or reduction. Patients may require use of blood product support and/or growth factors.
Lenalidomide has demonstrated a significantly increased risk of deep vein thrombosis (DVT) and pulmonary embolism (PE), as well as risk of myocardial infarction and stroke in patients with multiple myeloma who were treated with lenalidomide and dexamethasone therapy. Monitor for and advise patients about the signs and symptoms of thromboembolism. Advise patients to seek immediate medical care if they develop symptoms such as shortness of breath, chest pain, or arm or leg swelling. Thromboprophylaxis is recommended and the choice of regimen should be based on an assessment of the patient's underlying risks.
Note: Thromboprophylaxis is recommended when used in combination with chemotherapy and/or dexamethasone for the treatment of multiple myeloma and may be offered to other high-risk patients when clinically appropriate; thromboprophylaxis regimen should be based on assessment of patient- and disease-specific risk factors as well as concomitant therapy (Ref). Institute appropriate management if at risk for tumor lysis syndrome.

a Maintain appropriate number of treatment days per cycle based on indication and/or protocol. b Patients with multiple myeloma and decreased CrCl may experience an improvement in kidney function (often during the first cycle of therapy) when treatment with lenalidomide is initiated; frequent CrCl measurement and subsequent dose adjustment should be considered (Chen 2020). c Monitor kidney function closely, as acute kidney injury (usually occurring within the first 8 weeks of lenalidomide therapy) occurred in ~66% of patients in one report (Specter 2010). d It may be preferable to use full doses down to a CrCl of 50 mL/minute, as underdosing has been suggested (Chen 2020), and other multiple myeloma studies have successfully used full dose lenalidomide in patients with CrCl ≥50 mL/minute (Bridoux 2016; Dimopoulos 2010; Dimopoulos 2016; Mikhael 2018). e Approximately 30% removed during a 4-hour hemodialysis session (Chen 2007; manufacturer's labeling). f Dimopoulos 2016b. g Based on expert opinion. h Chen 2007. i Lichtman 2014. | ||||

CRRT: Drug clearance is dependent on the effluent flow rate, filter type, and method of renal replacement. Recommendations are based on high-flux dialyzers and effluent flow rates of 20 to 25 mL/kg/hour (or ~1,500 to 3,000 mL/hour) and minimal residual kidney function unless otherwise noted. Appropriate dosing requires consideration of adequate drug concentrations and consideration of initial loading doses. Close monitoring of response and adverse reactions (eg, neutropenia, thrombocytopenia) due to drug accumulation is important.
Oral: There are no data available to guide specific dosing recommendations. However, lenalidomide is likely removed by CRRT, therefore, dosing as for patients with CrCl 15 to <30 mL/minute is suggested with close monitoring (Ref).
PIRRT (eg, sustained, low-efficiency diafiltration): Drug clearance is dependent on the effluent flow rate, filter type, and method of renal replacement. Appropriate dosing requires consideration of adequate drug concentrations and consideration of initial loading doses. Close monitoring of response and adverse reactions (eg, neutropenia, thrombocytopenia) due to drug accumulation is important.
Oral:
PIRRT days: There are no data available to guide specific dosing recommendations. However, lenalidomide is likely removed by PIRRT, therefore, dosing as for patients with CrCl 15 to <30 mL/minute is suggested with close monitoring; administer dose after PIRRT session has ended (Ref).
Non-PIRRT days: Dose as for CrCl <15 mL/minute (Ref).
Hepatic impairment prior to treatment initiation:
Mild impairment (total bilirubin >1 to 1.5 times ULN or any AST > ULN): There are no dosage adjustments provided in the manufacturer's labeling; however, lenalidomide disposition is not influenced by mild impairment.
Moderate or severe impairment: There are no dosage adjustments provided in the manufacturer's labeling (has not been studied).
Hepatotoxicity during treatment: Interrupt lenalidomide for abnormal hepatic function tests; may consider resuming treatment at a lower dose upon return to baseline.
Note: Other concomitant anticancer therapies may also require dosage modification.
Hematologic toxicities: Note: Hematologic toxicity may require the use of blood product support and/or growth factors.

Lenalidomide may cause significant neutropenia and thrombocytopenia. Eighty percent of patients with deletion 5q myelodysplastic syndromes (MDS) had to have initial dose delay/reduction and 34% of patients had to have a second dose delay/reduction during the major study. Grade 3 or 4 hematologic toxicity occurred in 80% of patients enrolled in the study. Rates and severity of hematologic toxicity may vary by indication and dosing schedule (lowest rates with lymphoma and highest with MDS, with myeloma rates in between). Median time to documented recovery of grade 3 or 4 neutropenia was 17 days and grade 3 or 4 thrombocytopenia was 22 days. Lenalidomide is known to increase risk of fatal infections due to neutropenia (Ref).
Mechanism: Not clearly established; however, lenalidomide has multiple immunomodulatory affects that lead to decreased cell proliferation, including loss of PU.1, a key transcription factor involved in granulopoiesis, which leads to transient arrest of neutrophil maturation and subsequent neutropenia. Other mechanisms include modulation and downregulation of inflammatory cytokines, modulation of B-, T-, and NK-cells, as well as effects on the bone marrow microenvironment (Ref).
Onset: Delayed; median time to onset of grade 3 or 4 neutropenia was 42 days and grade 3 or 4 thrombocytopenia was 28 days. Data suggest incidence of infection is highest in initial months of drug treatment (Ref).
Risk factors:
• MDS deletion 5q versus other indications
• Concurrent use of other myelosuppressive therapies
• Preexisting kidney impairment
• Multiple myeloma disease-related complications that increase the risk of infection (eg, fractures, neutropenia, neurodegenerative disease) (Ref)
Lenalidomide may cause abnormal hepatic function tests (Ref). Rarely, hepatic failure (including fatal) has been reported in patients treated with combination lenalidomide and dexamethasone therapy. The pattern of liver injury may have cholestatic, hepatocellular, or mixed characteristics (Ref). Discontinuation of therapy has resulted in normalization of liver function tests in ~2 to 3 weeks (range: 8 to 30 days) (Ref)
Mechanism: Not clearly established; may have direct hepatotoxic effects. Proposed mechanisms also include changes in vascular inflow or outflow, possibly related to thrombotic effects of lenalidomide (Ref).
Onset: Intermediate; 7 to 10 days after initiation have been reported (Ref)
Risk factors:
• Preexisting liver disease
• Baseline elevations in liver enzymes
• Concurrent hepatotoxic medications
• Preexisting kidney impairment (Ref)
Immediate (eg, anaphylaxis, angioedema) (Ref) and delayed hypersensitivity reactions have been reported. Delayed hypersensitivity reactions include mild reactions most often described as maculopapular or morbilliform skin rashes or urticaria occurring in ~40% of patients (Ref). Severe cutaneous adverse reactions (SCARs), including drug rash with eosinophilia and systemic symptoms (DRESS) (Ref) and Stevens-Johnson syndrome/toxic epidermal necrolysis (SJS/TEN) (Ref) have been documented; some events have been fatal. Lenalidomide has also been associated with other delayed hypersensitivity reactions, including myocarditis (Ref) and hypersensitivity pneumonitis (Ref).
Mechanism: Immediate hypersensitivity reactions (eg, anaphylaxis, urticaria): non–dose-related, immunologic, IgE-mediated. Delayed hypersensitivity reactions: Non–dose-related, immunologic, T-cell mediated (Ref).
Onset: Immediate hypersensitivity reactions: Rapid; occur within 1 hour of administration but may occur up to 6 hours after exposure (Ref). Delayed hypersensitivity reactions: Varied. Morbilliform and maculopapular rashes occurred a median of 3 weeks after initiation (Ref). SCARs occur 1 to 8 weeks after initiation (Ref); the median time to onset for lenalidomide-associated SJS was 24 days (Ref).
Risk factors:
• Cross-reactivity among immunomodulatory drugs (eg, thalidomide, lenalidomide, pomalidomide) is variable, despite the similarity in chemical structures (Ref)
• Systemic amyloidosis versus multiple myeloma indication (Ref)
• Possible association with specific HLA proteins (Ref)
Second primary malignancies, including hematologic (primarily acute myeloid leukemia [AML] and myelodysplastic syndrome [MDS]) and solid tumor malignancies, and non-melanoma skin cancers, have been reported with lenalidomide when used for the treatment of MDS and multiple myeloma. Overall risk is low, multifactorial, and partially related to length of patient survival and the susceptibility of multiple myeloma to additional malignancies (Ref).
Mechanism: Not clearly established; may be related to immunomodulatory effects on the tumor microenvironment, favoring the escape/growth of abnormal clones that could result in second primary malignancy development. With MDS and AML, may be related to the stem-cell damaging effects through a ubiquitin/cereblon-based inhibition pathway. Another proposal is that the increased survival benefit provided by the drug increases the likelihood of development of second primary malignancies due to time, rather than a direct drug effect itself (Ref).
Risk factors:
• Multiple myeloma as indication for treatment (Ref)
• Concurrent or previous melphalan therapy or other alkylating agents with or without previous autologous stem cell transplantation (Ref)
• History of radiotherapy (Ref)
• Older age (Ref)
• Males (Ref)
Lenalidomide and dexamethasone combination therapy has been associated with a significant increased risk for arterial and venous thromboembolic events (VTE) in patients with multiple myeloma. Deep vein thrombosis (DVT), pulmonary embolism (PE), acute myocardial infarction (MI), and cerebrovascular accident have been reported (Ref).
Mechanism: May be related to increased platelet aggregation, single-nucleotide sequence variants and altered balance between procoagulant and anticoagulant proteins on the surface of endothelial cells (Ref).
Onset: Delayed; median treatment durations prior to thromboembolic events ranged from 2 to 34 cycles (Ref).
Risk factors:
• History of arterial or VTE (Ref)
• Underlying comorbidities known to increase VTE risk (eg, infection, diabetes, cardiac disease, inherited thrombophilia) (Ref)
• Concurrent therapies (eg, higher doses of corticosteroids, doxorubicin, multi-agent chemotherapy, erythropoiesis stimulating agents, estrogen) (Ref)
• Cardiovascular comorbidities (eg, hyperlipidemia, hypertension)
• Smoking
• Older age (Ref)
• Immobilization (Ref)
• Surgery (Ref)
• Use of central venous catheters (Ref)

Canadian labeling: Additional contraindications (not in the US labeling): Platelet count <50,000/mm3 (in patients with myelodysplastic syndromes); hypersensitivity to thalidomide or pomalidomide; patients capable of becoming pregnant; breastfeeding; male patients unable to follow or comply with required contraceptive measures.
Concerns related to adverse effects:
• CNS effects: May cause dizziness or fatigue; caution patients about performing tasks that require mental alertness (eg, operating machinery, driving).
• Tumor flare: Tumor flare reactions, including fatalities, have been observed in studies of lenalidomide for the treatment of chronic lymphocytic leukemia (CLL) and lymphomas; clinical presentation includes low grade fever, pain, rash, and tender lymph node swelling. In patients with mantle cell lymphoma, follicular lymphoma, and/or marginal zone lymphoma, tumor flare may mimic disease progression. In clinical trials, the majority of tumor flare events occurred in the first cycle of therapy.
• Tumor lysis syndrome: Tumor lysis syndrome (with fatalities) has been reported with lenalidomide. Patients with a high tumor burden may be at risk for tumor lysis syndrome.
Disease-related concerns:
• Heart failure: In a scientific statement from the American Heart Association, lenalidomide has been determined to be an agent that may either cause direct myocardial toxicity or exacerbate underlying myocardial dysfunction (magnitude: major) (AHA [Page 2016]).
• Kidney impairment: Use with caution in patients with kidney impairment; may experience an increased rate of toxicities due to reduced clearance and increased half-life.
• Mantle cell lymphoma: An increased incidence of early deaths (within 20 weeks) was reported in one study of patients receiving lenalidomide for the treatment of mantle cell lymphoma. Risk factors for early death include high tumor burden, mantle cell lymphoma international prognostic index (MIPI) score at diagnosis, and high WBC count (≥10,000/mm3) at baseline.
• Multiple myeloma: An increase in mortality was noted in 2 clinical studies in patients with multiple myeloma who received pembrolizumab in combination with a thalidomide analogue and dexamethasone. Pembrolizumab should not be used to treat multiple myeloma in combination with a thalidomide analogue and dexamethasone unless as part of a clinical trial.
• Stem cell mobilization: Lenalidomide use (≥4 cycles) may decrease the number of CD34+ cells collected for autologous hematopoietic cell transplant. Transplant eligible patients receiving lenalidomide should be referred to an appropriate transplant center in order to optimize the timing of stem cell collection. Cyclophosphamide in combination with G-CSF or G-CSF in combination with a CXC chemokine receptor 4 inhibitor (eg, plerixafor) may be considered when CD34+ cell collection is impaired.
Special populations:
• Older adult: Certain adverse reactions (DVT, PE, atrial fibrillation, renal failure) are more likely in patients >65 years of age; in some studies, the incidence of grade 3 or 4 adverse reactions was higher in older adults.
• Pediatric: If used in patients between 12 to 18 years of age, the parent or legal guardian must agree to ensure compliance with the Lenalidomide REMS program.
Other warnings/precautions:
• Appropriate use: In a clinical trial comparing lenalidomide versus chlorambucil single agent therapy in patients >65 years of age with chronic lymphocytic leukemia patients (not an FDA-approved indication), increased mortality was observed in the lenalidomide treatment arm. Atrial fibrillation, cardiac failure, and MI were observed more frequently in lenalidomide-treated patients; lenalidomide (alone or in combination) is not currently recommended for first-line treatment of CLL.
• REMS program: Due to the embryo-fetal risk, lenalidomide is only available through a restricted program under the Lenalidomide REMS program. Prescribers and pharmacies must be certified with the program to prescribe or dispense lenalidomide. Lenalidomide should only be prescribed to patients who can understand and comply with the conditions of the Lenalidomide REMS program.
• Blood donation: Patients should be advised not to donate blood during lenalidomide treatment and for 4 weeks following completion of therapy.
• Lactose intolerance: Product may contain lactose; avoid use in patients with congenital lactase deficiency, glucose-galactose malabsorption, or glucose intolerance.

Verify pregnancy status prior to therapy. Patients who could become pregnant should be treated only if they are able to comply with the conditions of the Lenalidomide REMS program. Patients who could become pregnant must avoid pregnancy beginning 4 weeks prior to therapy, during therapy, during therapy interruptions, and for at least 4 weeks after therapy is discontinued. Two negative pregnancy tests (sensitivity of at least 50 milliunits/mL) are required prior to starting lenalidomide treatment. The first test must be done 10 to 14 days prior to therapy, and the second within 24 hours prior to beginning therapy; additional pregnancy testing must be done weekly during the first 4 weeks, and every 4 weeks (every 2 weeks for patients with irregular menstrual cycles) thereafter. Lenalidomide must be immediately discontinued for a missed period, abnormal pregnancy test, or abnormal menstrual bleeding; refer patient to a reproductive toxicity specialist if pregnancy occurs during treatment. False-positive pregnancy tests have been reported during lenalidomide therapy (Castaneda 2018; Helm 2021).
Two forms of effective/reliable contraception (eg, tubal ligation, IUD, hormonal birth control methods, male latex or synthetic condom, diaphragm, or cervical cap) or total abstinence from heterosexual intercourse must be used unless the patient is infertile or has had a hysterectomy.
Lenalidomide is also present in semen. Patients (including those vasectomized) with partners who could become pregnant should use a latex or synthetic condom during any sexual contact with patients who could become pregnant, during lenalidomide treatment, during treatment interruptions, and for 4 weeks after discontinuation. Patients should not donate sperm during, for 4 weeks after treatment, and during lenalidomide therapy interruptions.
Based on the mechanism of action and data from animal reproduction studies, in utero exposure to lenalidomide may cause fetal harm.
Use of lenalidomide is contraindicated in pregnant patients. Lenalidomide is a thalidomide analogue, which is known to cause severe, life-threatening human birth defects. Exposure to lenalidomide during pregnancy may cause birth defects or embryo-fetal death. Discontinue immediately if pregnancy occurs during treatment.
Data collection to monitor outcomes following exposure to lenalidomide during pregnancy, including pregnant partners of male patients, is ongoing. Any suspected fetal exposure should be reported to the FDA via the MedWatch program (1-800-FDA-1088) and to the REM Call Center (1-888-423-5436).
It is not known if lenalidomide is present in breast milk.
Due to the potential for serious adverse reactions in the breastfed infant, breastfeeding is not recommended by the manufacturer.
CBC with differential (mantle cell lymphoma - weekly for the first cycle, every 2 weeks during cycles 2 to 4 and monthly thereafter; myelodysplastic syndrome - weekly for first 8 weeks and at least monthly thereafter; multiple myeloma - weekly for the first 2 cycles, every 2 weeks during the third cycle and monthly thereafter; follicular and marginal zone lymphoma – weekly for the first 3 weeks in cycle 1 and every 2 weeks in cycles 2 to 4 and monthly thereafter; also monitor as clinically indicated); renal function (eg, serum creatinine), LFTs (periodically). Thyroid function tests (TSH at baseline then every 2 to 3 months during lenalidomide treatment [Hamnvik 2011]). ECG when clinically indicated. Monitor for signs and symptoms of infection (if neutropenic), bleeding or bruising, hepatotoxicity, secondary malignancies, thromboembolism (eg, shortness of breath, chest pain, arm or leg swelling), dermatologic toxicity, tumor lysis syndrome, or hypersensitivity. Monitor for tumor flare reaction in patients with mantle cell lymphoma, follicular lymphoma, and/or marginal zone lymphoma. Monitor for development of second primary malignancies. Monitor adherence.
Patients who could become pregnant: Pregnancy test 10 to 14 days and 24 hours prior to initiating therapy, weekly during the first 4 weeks of treatment, then every 2 to 4 weeks through 4 weeks after therapy discontinued.
The American Society of Clinical Oncology hepatitis B virus (HBV) screening and management provisional clinical opinion (ASCO [Hwang 2020]) recommends HBV screening with hepatitis B surface antigen, hepatitis B core antibody, total Ig or IgG, and antibody to hepatitis B surface antigen prior to beginning (or at the beginning of) systemic anticancer therapy; do not delay treatment for screening/results. Detection of chronic or past HBV infection requires a risk assessment to determine antiviral prophylaxis requirements, monitoring, and follow-up.
Lenalidomide has immunomodulatory, antiangiogenic, and antineoplastic characteristics via multiple mechanisms. It selectively inhibits secretion of proinflammatory cytokines (potent inhibitor of tumor necrosis factor-alpha secretion); enhances cell-mediated immunity by stimulating proliferation of anti-CD3 stimulated T cells (resulting in increased IL-2 and interferon gamma secretion); inhibits trophic signals to angiogenic factors in cells. Inhibits the growth of myeloma, myelodysplastic, and lymphoma tumor cells by inducing cell cycle arrest and cell death. The addition of lenalidomide to rituximab increases antibody dependent cell-mediated cytotoxicity in follicular lymphoma and marginal zone lymphoma and increases tumor cell apoptosis in follicular lymphoma (compared to rituximab alone).
Protein binding: ~30%.
Half-life elimination: 3 to 5 hours.
Time to peak, plasma: MDS or myeloma patients: 0.5 to 6 hours.
Excretion: Urine (~82%; as unchanged drug).
Altered kidney function: The half-life is increased 3-fold in moderate (CrCl 30 to 49 mL/minute) to severe (CrCl <30 mL/minute) kidney impairment and increased ~4.5-fold in hemodialysis patients, compared to healthy patients. There is a 66% to 75% decrease in drug clearance in patients with moderate (CrCl 30 to 49 mL/minute) and severe (CrCl <30 mL/minute) kidney impairment compared with healthy subjects. Hemodialysis patients had an 80% decrease in drug clearance compared with healthy subjects.
