Pharmacological Properties

Pharmacodynamics

Mechanism of Action

The mechanism of action of lenalidomide is based on its antineoplastic, antiangiogenic, proerythropoietic, and immunomodulatory properties. Lenalidomide inhibits the proliferation of certain hematopoietic tumor cells, including plasma cells in multiple myeloma (MM) and cells with chromosome 5 cytogenetic abnormalities. Lenalidomide enhances T-cell and natural killer (NK) cell-mediated cellular immunity and increases the number of NK T-cells. Lenalidomide inhibits angiogenesis by blocking endothelial cell migration and adhesion and microvessel formation, enhances fetal hemoglobin production by CD34+ hematopoietic stem cells, and suppresses the secretion of proinflammatory cytokines (e.g., tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6)) by monocytes.

In myelodysplastic syndrome with del(5q), lenalidomide has been shown to selectively inhibit the abnormal clone by increasing apoptosis of del(5q) cells.

Lenalidomide binds directly to cereblon protein, a component of the Cullin E3 ubiquitin ligase enzyme complex, which includes DNA damage-binding protein 1 (DDB1), Cullin 4 (CUL4), and regulator of cullin 1 (Roc1). In the presence of lenalidomide, cereblon binds to substrate proteins Aiolos and Ikaros, which are lymphoid transcription factors, leading to their ubiquitination and subsequent degradation, resulting in cytotoxic and immunomodulatory effects.

Pharmacokinetics

Lenalidomide has an asymmetric carbon atom and therefore can exist in two optically active forms, S(-) and R(+). Lenalidomide is a racemic mixture of these isomers. Lenalidomide is generally well soluble in organic solvents and achieves maximum solubility in 0.1N HCl buffer solution.

Absorption

Lenalidomide is rapidly absorbed after oral administration under fasting conditions in healthy volunteers, with peak plasma concentration (Cmax) reached within 0.5 to 2 hours after dosing. In patients as well as in healthy volunteers, Cmax and area under the plasma concentration-time curve (AUC) increase proportionally with dose. Repeated administration does not result in significant accumulation of the drug. In plasma, the relative exposure of S- and R-enantiomers of lenalidomide is approximately 56% and 44%, respectively.

Concomitant intake with a high-fat, high-calorie meal reduces the extent of drug absorption, resulting in approximately a 20% decrease in AUC and a 50% reduction in Cmax in plasma. However, in the main pre-registration clinical trials in multiple myeloma and myelodysplastic syndrome, where the efficacy and safety of lenalidomide were established, the drug was administered without regard to food intake. Therefore, lenalidomide can be administered independently of food.

Population pharmacokinetic analysis indicates that the rate of absorption following oral administration of lenalidomide is similar in patients with multiple myeloma, myelodysplastic syndrome, and mantle cell lymphoma.

Distribution

In vitro, binding of (14C)-lenalidomide to plasma proteins in patients with multiple myeloma and in healthy volunteers is low, averaging 23% and 29%, respectively.

Lenalidomide is present in human semen (< 0.01% of dose) after administration at 25 mg per day and is not detectable 3 days after discontinuation of the drug (see section "Special Warnings and Precautions").

Metabolism and Elimination

Human metabolism study data based on in vitro findings demonstrate that cytochrome P450 isoenzymes are not involved in the metabolism of lenalidomide; therefore, pharmacokinetic interactions with drugs that inhibit cytochrome P450 isoenzymes are unlikely. In vitro studies show no inhibitory effect of lenalidomide on CYP1A2, CYP2C9, CYP2C19, CYP2D6, CYP2E1, CYP3A, or UGT1A1 isoenzymes. Thus, lenalidomide is unlikely to cause any clinically significant drug-drug interactions when coadministered with substrates of these enzymes.

According to in vitro study data, lenalidomide is not a substrate of the human breast cancer resistance protein (BCRP), multidrug resistance-associated protein (MRP) transporters MRP1, MRP2, or MRP3, organic anion transporters (OAT) OAT1 and OAT3, organic anion transporting polypeptide 1B1 (OATP1B1), organic cation transporters (OCT) OCT1 and OCT2, multidrug and toxin extrusion protein (MATE) MATE1, or organic cation transporters (OCTN) OCTN1 and OCTN2.

In vitro studies indicate that lenalidomide does not inhibit the human bile salt export pump (BSEP), BCRP, MRP2, OAT1, OAT3, OATP1B1, OATP1B3, or OCT2.

Most of lenalidomide is excreted in urine. Renal excretion accounts for 90% of total clearance in patients with normal renal function, and 4% of lenalidomide is excreted in feces.

Lenalidomide is minimally metabolized in the body; 82% of the dose is excreted unchanged in urine. Hydroxy-lenalidomide and N-acetyl-lenalidomide account for 4.59% and 1.83% of total excretion, respectively. Renal clearance of lenalidomide exceeds the glomerular filtration rate, indicating active secretion.

At doses of 5 to 25 mg per day, the plasma elimination half-life is approximately 3 hours in healthy volunteers and ranges from 3 to 5 hours in patients with multiple myeloma, myelodysplastic syndrome, or mantle cell lymphoma.

Elderly Patients

No specific clinical studies have been conducted to evaluate pharmacokinetics in elderly patients. Population pharmacokinetic analysis included patients aged 39 to 85 years. Results indicate that age does not affect lenalidomide clearance (plasma exposure). Due to the increased likelihood of impaired renal function in elderly patients, caution should be exercised in dose selection, and careful monitoring of renal function during therapy is recommended.

Patients with Renal Impairment

The pharmacokinetics of lenalidomide have been studied in patients with renal impairment due to non-malignant conditions. In this study, two methods were used to classify renal function: measurement of creatinine clearance (CrCl) in 24-hour urine and estimation of CrCl using the Cockcroft-Gault formula. Results show that with decreasing renal function (< 50 mL/min), total lenalidomide clearance decreases proportionally, leading to increased AUC.

AUC was increased approximately 2.5-, 4-, and 5-fold in patients with moderate, severe, and end-stage renal disease, respectively, compared to the group combining patients with normal renal function and those with mild renal impairment. The elimination half-life of lenalidomide increased from approximately 3.5 hours in patients with CrCl > 50 mL/min to more than 9 hours in patients with reduced renal function (CrCl < 50 mL/min). However, renal impairment does not alter the oral absorption of lenalidomide. Cmax was similar in healthy volunteers and patients with renal impairment. Approximately 30% of the drug is removed during a single 4-hour hemodialysis session. Recommended dose adjustments for patients with renal impairment are described in the section "Dosage and Administration."

Patients with Hepatic Impairment

Population pharmacokinetic analysis included patients with mild hepatic impairment (N=16, total bilirubin >1 to ≤1.5 x ULN (upper limit of normal) or AST > ULN). Results indicate that mild hepatic impairment does not affect lenalidomide clearance (plasma exposure). There are no available data on the use of the drug in patients with moderate to severe hepatic impairment.

Other Intrinsic Factors

Population pharmacokinetic analysis demonstrated that body weight (33–135 kg), sex, race, and type of hematologic malignancy (multiple myeloma, myelodysplastic syndrome, or mantle cell lymphoma) have no clinically significant effect on lenalidomide clearance in adult patients.

Contraindications.

  • Hypersensitivity to the active substance or to any of the excipients of the medicinal product (see section "Composition");
  • Pregnancy;
  • Reproductive age in women, except for those who comply with all requirements of the "Pregnancy Prevention Programme" (see sections "Special precautions" and "Use during pregnancy or breastfeeding").

Special precautions.

Pregnancy

Lenalidomide is a structural analogue of thalidomide. Thalidomide is a known human teratogen that may cause severe, life-threatening birth defects or fetal death.

Preclinical studies of lenalidomide in primates showed results similar to those described for thalidomide (see section "Use during pregnancy or breastfeeding"). Teratogenic effects are expected if lenalidomide is taken during pregnancy.

All female patients must comply with the requirements of the Pregnancy Prevention Programme, unless there is reliable evidence that the patient has no reproductive potential.

Criteria for women without reproductive potential

A female patient or a female partner of a male patient is considered to have no reproductive potential unless she meets at least one of the following criteria:

  • Age ≥ 50 years and, accordingly, has amenorrhea ≥ 1 year*;
  • Premature ovarian failure confirmed by a specialist gynecologist;
  • Previous bilateral salpingo-oophorectomy or hysterectomy;
  • Genotype XY, Turner syndrome, or uterine agenesis.

* Amenorrhea following cancer treatment or during lactation does not exclude the presence of reproductive potential.

Counselling

The use of lenalidomide in women with preserved reproductive potential is contraindicated except when all the following conditions are met:

Woman:

  • Understands the potential teratogenic effect of the drug on the fetus;
  • Understands the necessity of continuous use of effective contraception methods starting 4 weeks before treatment initiation, throughout the entire treatment course, and for 4 weeks after discontinuation of lenalidomide;
  • With reproductive potential, even if amenorrheic, must comply with all recommendations regarding effective contraception;
  • Must be able to adhere to effective contraceptive measures;
  • Must be informed and understand the possible consequences of pregnancy and the need for immediate consultation if there is a risk of becoming pregnant;
  • Understands the necessity to initiate lenalidomide treatment immediately after a negative pregnancy test;
  • Understands and agrees to undergo pregnancy testing every 4 weeks, except in cases of confirmed tubal sterilization;
  • Acknowledges that she understands the risks and the necessity of preventive measures associated with the use of lenalidomide.

Regarding men taking lenalidomide, pharmacokinetic data have shown that lenalidomide is present in semen at very low levels during treatment and is undetectable in healthy men within 3 days after treatment discontinuation.

As a precautionary measure, all male patients taking lenalidomide must meet the following requirements.

Man:

  • Must understand the expected teratogenic risk associated with sexual intercourse with a pregnant woman or a woman of reproductive potential;
  • Must always understand the necessity of using a condom during sexual intercourse with a pregnant woman or a woman of reproductive potential not using effective contraception methods during treatment and for 4 weeks after discontinuation (even if the man has undergone vasectomy); male patients taking lenalidomide must not donate semen for 4 weeks after discontinuation of the drug;
  • Must understand that if his partner becomes pregnant while he is taking lenalidomide or immediately after stopping it, he must immediately inform his physician; it is also recommended to refer the female partner to a physician specializing in or experienced in teratology for risk assessment and recommendations.

The prescribing physician must ensure that women with reproductive potential:

  • Comply with the requirements of the Pregnancy Prevention Programme, including confirmation that they properly understand the issue;
  • Acknowledge the above-mentioned conditions.

Contraception

Women with preserved reproductive potential must use one effective method of contraception for 4 weeks before starting treatment, during the entire treatment course, and for 4 weeks after treatment discontinuation with lenalidomide, even in case of temporary interruption of therapy, except when the patient confirms absolute and continuous abstinence from the drug for one month. If effective contraception is not achieved, the patient should be referred to a qualified healthcare provider for counseling on effective contraception to initiate it.

Acceptable methods of contraception include:

  • Implants;
  • Intrauterine levonorgestrel-releasing system (IUD);
  • Medicinal products containing medroxyprogesterone acetate;
  • Tubal sterilization;
  • Partner's vasectomy (vasectomy must be confirmed by two negative semen analyses);
  • Progesterone-containing oral contraceptives that suppress ovulation (desogestrel).

The use of combined oral contraceptives is not recommended in patients with multiple myeloma receiving lenalidomide as part of combination therapy, and to a lesser extent in patients with multiple myeloma, myelodysplastic syndrome, and mantle cell lymphoma receiving lenalidomide as monotherapy, due to an increased risk of venous thromboembolism. If a patient is currently using combined oral contraceptives, she should switch to one of the methods listed above. The risk of venous thromboembolism persists for 4–6 weeks after discontinuation of combined oral contraceptives. The effectiveness of hormonal contraceptives may be reduced when used concomitantly with dexamethasone (see section "Interaction with other medicinal products and other types of interactions").

The use of implants and intrauterine levonorgestrel-releasing systems is associated with an increased risk of infection during insertion and irregular vaginal bleeding. Patients, especially those with neutropenia, should carefully consider prophylactic antibiotic use.

Copper-containing IUDs are generally not recommended due to the potential risk of infection during insertion and menstrual bleeding, which may worsen the condition of patients with neutropenia or thrombocytopenia.

Pregnancy testing

According to local practice, pregnancy testing in women with reproductive potential must be performed under medical supervision as specified below. The minimum sensitivity of the test should be 25 mIU/mL. This requirement applies also to women of reproductive age practicing absolute and continuous abstinence. Pregnancy testing, prescription issuance, and drug dispensing must occur on the same day. Lenalidomide dispensing to women of reproductive age must occur within 7 days after prescription issuance.

Before starting treatment

Pregnancy testing must be performed under medical supervision during the consultation when lenalidomide has already been prescribed, or within 3 days before visiting the prescribing physician, if the patient has used effective contraception methods for at least the last 4 weeks. When starting lenalidomide treatment, the pregnancy test must confirm that the woman is not pregnant.

Subsequent and end of treatment

Pregnancy testing should be repeated under medical supervision every 4 weeks, including 4 weeks after treatment completion, except in cases of confirmed tubal sterilization. The pregnancy test should be performed on the day of prescription or within 3 days before visiting the prescribing physician.

Interaction with other medicinal products and other types of interactions.

Erythropoiesis-stimulating agents or other agents that may increase the risk of thrombosis (e.g., hormone replacement therapy) should be used with caution in patients with multiple myeloma receiving lenalidomide and dexamethasone (see sections "Special precautions" and "Adverse reactions").

Oral contraceptives

No drug interaction studies with oral contraceptives have been conducted. Lenalidomide is not an enzyme inducer. In vitro studies on human hepatocytes showed that lenalidomide, at various tested concentrations, does not induce cytochromes CYP1A2, CYP2B6, CYP2C9, CYP2C19, and CYP3A4/5. Therefore, when lenalidomide is used alone, induction leading to reduced efficacy of drugs, including hormonal contraceptives, is not expected. However, dexamethasone is known to be a weak or moderate inducer of CYP3A4 and likely affects other enzymes and transporters as well. A reduction in the effectiveness of oral contraception during treatment cannot be excluded. To effectively prevent pregnancy, methods specified in the Pregnancy Prevention Programme must be used (see sections "Special precautions" and "Use during pregnancy or breastfeeding").

Warfarin

Multiple doses of lenalidomide 10 mg do not affect the pharmacokinetics of a single dose of R- and S-warfarin. A single dose of 25 mg warfarin does not affect the pharmacokinetics of lenalidomide. However, it is unknown whether there is an interaction in clinical use (concomitant therapy with dexamethasone). Dexamethasone is a weak or moderate enzyme inducer; its effect on warfarin is unknown. Close monitoring of warfarin concentration is recommended during treatment.

Digoxin

Concomitant administration of lenalidomide 10 mg daily with digoxin increases digoxin plasma levels (0.5 mg, single dose) by 14% with a 90% CI (confidence interval) [0.52%–28.2%]. It is unknown whether the effect would differ during clinical use (higher doses of lenalidomide in combination with dexamethasone). Therefore, monitoring of digoxin concentration is recommended during lenalidomide treatment.

Statins

There is an increased risk of rhabdomyolysis when statins are used with lenalidomide. Therefore, close clinical and laboratory monitoring is recommended during the first weeks of treatment.

Dexamethasone

Concomitant administration of one or multiple doses of dexamethasone (40 mg once daily) has no clinically significant effect on the pharmacokinetics of multiple doses of lenalidomide (25 mg daily).

Interaction with P-glycoprotein (P-gp) inhibitors

Lenalidomide is a substrate of P-gp, but not its inhibitor, in vitro. Concomitant administration of multiple doses of the strong P-gp inhibitor quinidine (600 mg twice daily) or the moderate P-gp inhibitor/substrate temsirolimus (25 mg) does not show a clinically significant effect on the pharmacokinetics of lenalidomide (25 mg daily). Concomitant administration of lenalidomide does not alter the pharmacokinetics of temsirolimus.

Special precautions.

Additional warnings

Patients must not give this medicinal product to others; unused capsules should be returned to the healthcare facility after completion of treatment for safe disposal.

Patients should not donate blood during treatment and for 1 week after discontinuation of lenalidomide.

Healthcare professionals and caregivers handling the blister pack or capsules must wear disposable gloves.

Pregnant women or women who suspect they may be pregnant must not touch the blister pack or capsules.

Educational materials, prescribing and dispensing restrictions

To help patients prevent fetal exposure to lenalidomide, the marketing authorization holder must provide healthcare professionals with educational materials containing information to reinforce the warning regarding the expected teratogenic effect of lenalidomide, recommendations for contraception prior to initiating therapy, and the necessity of pregnancy testing. The physician must inform both male and female patients about the teratogenic risk of lenalidomide and the strict measures to prevent pregnancy, as outlined in the Pregnancy Prevention Programme (see sections "Special safety measures" and "Use during pregnancy or breastfeeding"), and must provide the patient with an educational brochure and a patient card and/or equivalent document according to the implemented national patient card system. A national controlled distribution system has been established in cooperation with each national competent authority. The controlled distribution system includes the use of a patient card and/or equivalent document to monitor prescribing and/or dispensing, and collection of detailed prescription data to enable thorough national monitoring of off-label use of the medicinal product. Ideally, pregnancy testing, treatment initiation, and dispensing of the medicinal product should occur on the same day. Dispensing of lenalidomide to women of reproductive potential must occur within 7 days of treatment initiation and a negative pregnancy test result. Dispensing of the medicinal product to women of childbearing potential should not exceed 4 weeks of treatment; for all other patient categories, dispensing should not exceed 12 weeks.

Other special warnings and precautions for use

Myocardial infarction

Myocardial infarction has been reported in patients receiving lenalidomide, particularly in those with known risk factors and during the first 12 months of treatment when used in combination with dexamethasone. Close monitoring is required for patients with known risk factors, including history of thrombosis, and preventive measures should be taken to minimize all modifiable risk factors (e.g., smoking, arterial hypertension, hyperlipidemia).

Venous and arterial thromboembolism

In patients with multiple myeloma, combination therapy with lenalidomide and dexamethasone is associated with an increased risk of venous thromboembolism (mainly deep vein thrombosis and pulmonary embolism) and arterial thromboembolism (mainly myocardial infarction and cerebrovascular events), which is less pronounced with lenalidomide in combination with melphalan and prednisolone (see sections "Interaction with other medicinal products and other forms of interaction" and "Adverse reactions"). In patients with myelodysplastic syndromes, mantle cell lymphoma, and multiple myeloma, monotherapy with lenalidomide has been associated with a risk of venous thromboembolism (mainly deep vein thrombosis and pulmonary embolism), but to a lesser extent than in patients with multiple myeloma treated with lenalidomide as part of combination therapy. The risk of arterial thromboembolic complications in patients with multiple myeloma is lower with lenalidomide monotherapy than with combination therapy. Therefore, close monitoring is required for patients with known risk factors for thromboembolism, including a history of thrombosis. Preventive measures should be taken to minimize all modifiable risk factors (e.g., smoking, arterial hypertension, hyperlipid游戏副本

Method of Administration and Dosage

Treatment should be administered under the supervision of a physician experienced in the use of anticancer therapies.

For all indications listed below:

  • the dose should be modified based on clinical and laboratory assessments (see sections "Special Precautions" and "Special Instructions for Use");
  • for dose adjustment during treatment and re-treatment, thrombocytopenia grade III–IV, neutropenia, or any other toxicity of grade III or IV considered related to lenalidomide should be taken into account;
  • in case of neutropenia, consideration should be given to the use of growth factors in patient management;
  • if less than 12 hours has passed since a missed dose, the patient may take the dose; if more than 12 hours have passed since the missed dose, the patient should not take the missed dose and should take the next dose at the scheduled time on the following day.

Method of Administration

Oral administration. Lenalidomide capsules should be taken at the same time each day according to the prescribed schedule. Capsules must not be opened, crushed, or chewed. Capsules should be swallowed whole, preferably with water, independent of food intake. It is recommended to press only one end of the capsule when removing it from the blister pack, thereby minimizing the risk of capsule deformation or breakage.

Dosage

Newly Diagnosed Multiple Myeloma

Maintenance Therapy with Lenalidomide in Patients Who Have Undergone Autologous Stem Cell Transplantation (ASCT)

Maintenance therapy with lenalidomide should be initiated after adequate hematologic recovery following ASCT in patients without evidence of disease progression. Lenalidomide treatment should not be initiated if the absolute neutrophil count (ANC) is <1.0 × 10⁹/L and/or platelet count is <75 × 10⁹/L.

Recommended Dose

The recommended initial dose of lenalidomide is 10 mg orally once daily, continuously (days 1 to 28 of repeated 28-day cycles), administered until disease progression or until unacceptable toxicity occurs. After 3 cycles of lenalidomide maintenance therapy, the dose may be increased to 15 mg orally once daily, provided tolerability is good.

a. At the physician's discretion, if neutropenia is the only toxicity at any dose level, add G-CSF.

Mantle cell lymphoma (MCL) or follicular lymphoma

Tumor lysis syndrome (TLS)

All patients should receive prophylaxis for TLS (with allopurinol, rasburicase, or an equivalent agent according to established guidelines) and maintain adequate hydration (orally) during the first week of the first cycle or for a longer period if clinically indicated. To monitor for TLS, patients should undergo weekly blood biochemistry testing during the first cycle and as clinically indicated.

Lenalidomide treatment may be continued (at maintenance dose) in patients with laboratory TLS or clinical Grade I TLS, or, at the physician’s discretion, the lenalidomide dose may be reduced by one level and treatment continued. Intensive intravenous hydration and appropriate medical support should be provided according to local treatment standards until electrolyte imbalances are resolved. Rasburicase may be required to manage hyperuricemia. Hospitalization is at the physician’s discretion.

In patients with clinical TLS Grade II to IV, lenalidomide should be discontinued, and weekly blood biochemistry tests should be performed or conducted as clinically indicated. Intensive intravenous hydration and appropriate medical support should be provided according to local treatment standards until electrolyte imbalances are resolved. The use of rasburicase and hospitalization are at the physician’s discretion. After TLS has resolved to Grade 0, lenalidomide treatment may be resumed at a reduced dose, as determined by the physician.

Tumor flare reaction

Patients with Grade I–II tumor flare reaction (TFR) may continue lenalidomide without interruption or dose modification, at the physician’s discretion. The physician may prescribe therapy with NSAIDs, short-acting corticosteroids, and/or narcotic analgesics.

In patients with Grade III–IV TFR, lenalidomide should be discontinued and treatment initiated with NSAIDs, short-acting corticosteroids, and/or narcotic analgesics until TFR resolves to ≤ Grade I, after which lenalidomide treatment may be resumed at the same dose level for the remainder of that cycle. Patients may receive symptomatic treatment according to recommendations for Grade I–II TFR.

All indications

In cases of Grade III or IV toxicity considered related to lenalidomide, treatment should be discontinued. It may be resumed, at the physician’s discretion, only at the next lower dose level once toxicity has resolved to ≤ Grade II.

For Grade II–III skin rashes, lenalidomide administration should be interrupted or withheld. Lenalidomide treatment should be permanently discontinued in cases of angioedema, Grade IV rash, exfoliative or bullous rash, or if Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN), or DRESS syndrome is suspected. Treatment should not be restarted after resolution of these reactions.

Special patient populations

Elderly patients

Lenalidomide has been used in clinical trials in patients with multiple myeloma up to 91 years of age, in patients with myelodysplastic syndrome up to 95 years of age, and in patients with mantle cell lymphoma up to 88 years of age. Since elderly patients are more likely to have reduced renal function, a cautious approach to dose selection is recommended, and monitoring of renal function should be considered.

Newly diagnosed multiple myeloma: transplant-ineligible patients

In patients aged 75 years and older with newly diagnosed multiple myeloma receiving lenalidomide, there was a higher incidence of new serious adverse reactions and adverse reactions leading to treatment discontinuation. A careful assessment of patients aged 75 years and older with newly diagnosed multiple myeloma is recommended prior to initiating treatment.

For patients aged 75 years and older receiving lenalidomide in combination with dexamethasone, the starting dose of dexamethasone is 20 mg daily on Days 1, 8, 15, and 22 of each 28-day treatment cycle.

Dose adjustment is not required for patients aged 75 years and older receiving lenalidomide in combination with melphalan and prednisolone. However, patients aged 75 years and older receiving lenalidomide have an increased risk of serious adverse reactions that may lead to treatment discontinuation.

In clinical studies of newly diagnosed myeloma in transplant-ineligible patients, the combination therapy with lenalidomide was less well tolerated in patients aged 75 years and older compared to younger patients. Discontinuation of the drug occurred at a higher rate due to intolerance (Grade III–IV adverse reactions and serious adverse reactions) in elderly patients compared to younger patients (under 75 years of age).

Multiple myeloma with at least one prior therapy

The proportion of patients with multiple myeloma aged 65 years and older did not differ significantly between groups receiving lenalidomide plus dexamethasone or placebo plus dexamethasone. No differences in safety and efficacy profiles were observed between these and younger patients, although increased susceptibility in elderly individuals cannot be ruled out.

Myelodysplastic syndromes

For patients with myelodysplastic syndromes receiving lenalidomide, there were no differences in safety and efficacy between patients aged 65 years and older and younger patients.

Since elderly patients are more likely to have reduced renal function, careful dose selection is required. Monitoring of renal function in these patients is also recommended.

Mantle cell lymphoma

For patients with mantle cell lymphoma receiving lenalidomide, no differences in safety and efficacy were observed between patients aged 65 years and older and younger patients.

Since elderly patients are more likely to have reduced renal function, careful dose selection is required, and monitoring of renal function is recommended in these patients.

Follicular lymphoma

In patients with follicular lymphoma receiving lenalidomide in combination with rituximab, the overall frequency of adverse reactions was similar in patients aged 65 years and older compared to younger patients. No overall differences in efficacy were observed between the two age groups.

Patients with renal impairment

Lenalidomide is primarily eliminated via the kidneys; patients with more severe renal impairment may tolerate treatment less well. Caution is advised in dose selection, and monitoring of renal function is recommended.

Dose adjustment is not required for patients with mild renal impairment and multiple myeloma, myelodysplastic syndrome, mantle cell lymphoma, or follicular lymphoma. The following dose adjustments are recommended at the start of treatment and during therapy for patients with moderate or severe renal impairment or for patients with end-stage renal disease (ESRD).

There are no data from Phase III clinical trials in patients with ESRD (creatinine clearance < 30 mL/min requiring dialysis).

2 - For patients starting at a dose of 10 mg, in case of dose reduction due to grade III or IV neutropenia or thrombocytopenia, or other grade III or IV toxic effects. If a toxic effect related to lenalidomide develops, doses below 5 mg every other day or 2.5 mg once daily should not be administered.

After initiation of lenalidomide treatment, subsequent dose adjustments in patients with renal impairment should be based on individual patient tolerability as described above.

Patients with hepatic impairment

The use of lenalidomide has not been formally studied in patients with hepatic dysfunction, and there are no specific recommendations for dose selection.

Children

For safety reasons, lenalidomide should not be used in children and adolescents under 18 years of age.

Overdose

There are no specific data regarding lenalidomide overdose, although in dose-finding studies some patients received up to 150 mg, and in single-dose studies some patients received doses up to 400 mg. The dose-limiting toxicity in these studies was primarily hematological. In case of overdose, supportive therapy is recommended.

Description of individual adverse reactions

Teratogenicity

Lenalidomide is a structural analogue of thalidomide. Thalidomide is a known human teratogen that can cause severe, life-threatening birth defects or fetal death.

Experimental studies of lenalidomide in monkeys showed results similar to those described for thalidomide. If lenalidomide is taken during pregnancy, its teratogenic effect is expected.

Neutropenia and thrombocytopenia

Patients with newly diagnosed multiple myeloma who underwent ASCT and received lenalidomide treatment

Maintenance therapy with lenalidomide after ASCT is associated with a higher incidence of grade IV neutropenia compared to placebo. In some cases, urgent management of neutropenia required discontinuation of lenalidomide treatment. The incidence of grade IV neutropenia in the lenalidomide maintenance therapy groups was comparable to placebo in both studies. Maintenance therapy with lenalidomide after ASCT is associated with a higher incidence of grade III or IV thrombocytopenia compared to placebo.

  • Newly diagnosed multiple myeloma in patients receiving lenalidomide in combination with low-dose dexamethasone

The combination of lenalidomide with low-dose dexamethasone in patients with newly diagnosed multiple myeloma was associated with a reduced incidence of grade III-IV neutropenia. Grade IV febrile neutropenia was observed less frequently.

  • Newly diagnosed multiple myeloma in patients taking lenalidomide in combination with melphalan and prednisolone

The combination of lenalidomide with melphalan and prednisolone in patients with newly diagnosed multiple myeloma was associated with an increased incidence of grade III-IV neutropenia. Episodes of grade IV febrile neutropenia were observed more frequently.

  • Multiple myeloma with at least one prior line of therapy

The use of the combination of lenalidomide with dexamethasone in patients with multiple myeloma is associated with an increased incidence of grade III-IV neutropenia. Episodes of grade IV febrile neutropenia were observed less frequently.

  • Myelodysplastic syndromes

In patients with myelodysplastic syndrome, the use of lenalidomide is associated with a higher incidence of grade III-IV neutropenia. Episodes of grade III-IV febrile neutropenia were observed in 2.2% of patients receiving lenalidomide compared to 0.0% in the placebo group.

  • Mantle cell lymphoma

In patients with mantle cell lymphoma, the use of lenalidomide is associated with a higher incidence of grade III-IV neutropenia (43.7% of patients receiving lenalidomide compared to 33.7% in the control group).

  • Patients with follicular lymphoma

The use of the combination of lenalidomide with rituximab in follicular lymphoma is associated with a higher incidence of grade III or IV neutropenia (50.7% among patients receiving lenalidomide/rituximab compared to 12.2% among patients receiving placebo/rituximab). All cases of grade III or IV neutropenia were reversible upon discontinuation or dose reduction and/or use of supportive therapy with growth factors. Additionally, febrile neutropenia was infrequent (2.7% among patients receiving lenalidomide/rituximab compared to 0.7% among patients receiving placebo/rituximab).

The use of lenalidomide in combination with rituximab is also associated with a higher incidence of grade III or IV thrombocytopenia (1.4% among patients receiving lenalidomide/rituximab compared to 0% among patients receiving placebo/rituximab).

Venous thromboembolism

An increased risk of deep vein thrombosis (DVT) and pulmonary embolism (PE) is associated with the use of lenalidomide with dexamethasone in patients with multiple myeloma, and to a lesser extent in patients receiving lenalidomide in combination with melphalan and prednisolone or in patients with multiple myeloma, myelodysplastic syndrome, and mantle cell lymphoma receiving lenalidomide as monotherapy. Concomitant use of erythropoiesis-stimulating agents or a history of DVT may also increase the risk of thrombosis in these patients.

Myocardial infarction

Myocardial infarction has been reported in patients receiving lenalidomide treatment, particularly in those with existing risk factors.

Bleeding disorders

Bleeding disorders have been reported in several organ system classes: blood and lymphatic system disorders, nervous system disorders (intracranial hemorrhage); respiratory, thoracic and mediastinal disorders (epistaxis); gastrointestinal disorders (gingival bleeding, hemorrhoidal bleeding, rectal bleeding); renal and urinary disorders (hematuria); injury, poisoning and procedural complications (contusions); and vascular disorders (ecchymoses).

Allergic reactions

Cases of allergic reactions/hypersensitivity reactions have been reported. Cross-reactivity between lenalidomide and thalidomide has been reported in the literature.

Severe skin reactions

Cases of Stevens-Johnson syndrome, toxic epidermal necrolysis, and drug reaction with eosinophilia and systemic symptoms (DRESS) have been reported. Lenalidomide should not be prescribed to patients with a history of severe rashes associated with thalidomide treatment.

Secondary malignancies

In clinical trials involving patients previously treated for myeloma with lenalidomide and dexamethasone, secondary malignancies in the control group were predominantly basal cell or squamous cell skin cancers.

Acute myeloid leukemia

  • Multiple myeloma

Cases of acute myeloid leukemia (AML) were observed in clinical trials in patients with newly diagnosed multiple myeloma who received lenalidomide in combination with melphalan, or immediately after high-dose melphalan and ASCT (autologous stem cell transplantation). This increase was not observed in clinical trials of patients with newly diagnosed multiple myeloma receiving lenalidomide in combination with low-dose dexamethasone, compared to thalidomide in combination with melphalan and prednisolone.

  • Myelodysplastic syndromes

Baseline factors, including complex cytogenetic abnormalities and TP53 mutations, are associated with progression to AML in transfusion-dependent patients with the Del(5q) genetic abnormality. The estimated two-year cumulative risk of AML progression is 13.8% in patients with Del(5q) abnormality compared to 17.3% in patients with Del(5q) abnormality and one additional cytogenetic abnormality, and 38.6% in patients with a complex karyotype.

Hepatic disorders

In the post-marketing period, adverse reactions (frequency unknown) have been reported: acute liver failure and cholestasis (both potentially fatal), toxic hepatitis, cytolitic hepatitis, mixed cytolitic/cholestatic hepatitis.

Rhabdomyolysis

Rhabdomyolysis has been observed rarely, in some cases when lenalidomide was used concomitantly with statins.

Thyroid function disorders

Cases of hypothyroidism and hyperthyroidism have been reported.

Tumor flare reaction and tumor lysis syndrome

In a clinical trial of mantle cell lymphoma (MCL), a "tumor flare" reaction occurred in 13/134 (approximately 10%) of patients receiving lenalidomide treatment compared to 0% in the control group. Most cases occurred during the first cycle, were considered treatment-related, and were of grade I or II severity. All events occurred in cycle 1, and one patient experienced a recurrence of the "tumor flare" reaction in cycle 11. In the AUGMENT trial in patients with follicular lymphoma (FL) or marginal zone lymphoma, "tumor flare" reaction was reported in 19/176 (10.8%) patients in the lenalidomide/rituximab group; one patient in this group experienced a grade III tumor flare reaction. In the MAGNIFY trial, 9/222 (4.1%) patients experienced a "tumor flare" reaction; all reports were of grade I or II severity, one of which was serious. In a separate phase 2 MCL trial, one case of tumor flare reaction resulted in a fatal outcome. Patients with a high prognostic index for mantle cell lymphoma or generalized lymphadenopathy (at least one lesion ≥7 cm in the longest diameter) at the start of therapy may be at risk of tumor flare reaction. Cases of tumor lysis syndrome (TLS) have also been reported. Most cases occurred in the first cycle, were of grade I or II severity, and were considered treatment-related.

Gastrointestinal disorders

Gastrointestinal perforations have been reported during treatment with lenalidomide. Gastrointestinal perforations may lead to gastrointestinal bleeding and septic complications and may be associated with fatal outcomes.
