Label Section Quick Index

1 Indications And Usage

BEQALZI is indicated for the treatment of adult patients with relapsed or refractory mantle cell lymphoma (MCL) after at least two lines of systemic therapy, including a Bruton's tyrosine kinase (BTK) inhibitor.

This indication is approved under accelerated approval based on response rate and durability of response. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial(s) [see Clinical Studies (14.1)].

2.1 Important Safety Information

  • BEQALZI can cause tumor lysis syndrome (TLS), especially during the ramp-up phase or during restart after a dosage interruption [see Warnings and Precautions (5.1)].
  • Initiate BEQALZI with a dose ramp-up. For dose interruption lasting greater than 7 days, adjust the restart BEQALZI dose as instructed [see Dosage and Administration (2.3) and (2.4)].
  • Assess patient risk for TLS and whether hospitalization for monitoring is warranted.
  • Initiate prophylactic hydration and anti-hyperuricemics before the first dose of BEQALZI and continue as appropriate.
  • Correct pre-existing electrolyte abnormalities before the first dose.
  • Monitor blood chemistries closely [see Warnings and Precautions (5.1)].

2.2 Recommended Dosage For Mantle Cell Lymphoma

BEQALZI dosing begins with a 4-week ramp-up. The ramp-up dosing schedule is designed to gradually reduce tumor burden (debulk) and decrease the risk of TLS.

4-Week Dose Ramp-Up Schedule

Administer BEQALZI orally once daily, according to the ramp-up dosing schedule shown in Table 1.

4 Contraindications

Concomitant use of sonrotoclax with strong CYP3A inhibitors at initiation and during the ramp-up phase is contraindicated in patients due to the potential for increased risk of tumor lysis syndrome [see Drug Interactions (7.1)].

5.1 Tumor Lysis Syndrome

BEQALZI can cause serious or life-threatening tumor lysis syndrome (TLS). BEQALZI can cause rapid reduction in tumor and changes in blood chemistries consistent with TLS that require prompt management. This can occur as early as 4 hours after the first dose, at any dose increases, and upon restart following dosage interruption. Laboratory or clinical TLS occurred in 7% of the 115 patients with MCL who followed the recommended dose ramp-up.

Risk factors for TLS include higher tumor burden such as bulky lymphadenopathy or lymphocytosis and reduced renal function.

Assess all patients for TLS risk and provide appropriate prophylaxis, including hydration and anti-hyperuricemics begun prior to the first dose of BEQALZI. Correct relevant chemistry abnormalities prior to starting BEQALZI. Consider hospitalization with intravenous hydration and monitoring and employ more frequent monitoring for patients with high TLS risk. Monitor blood chemistries and manage abnormalities promptly. Interrupt dosing if needed; when restarting BEQALZI, follow the dose modification guidance [see Dosage and Administration (2.3)].

Concomitant use of sonrotoclax with strong or moderate CYP3A inhibitors increases sonrotoclax exposure, which may increase the risk of TLS at initiation and during the ramp-up phase [see Dosage and Administration (2.4) and Drug Interactions (7.1)].

5.2 Serious Infections

BEQALZI can cause fatal or serious infections [see Adverse Reactions (6.1)]. Among patients who received BEQALZI at the recommended dosage in the clinical trial, serious infections occurred in 14% of patients and Grade 3 or higher infections in 17%, with fatal infections in 2.6% of patients. The most common Grade 3 or greater infection was pneumonia (10%). Monitor for signs and symptoms of infection and treat appropriately. Consider prophylactic antimicrobials and immunoglobulins according to guidelines. Withhold or dose reduce BEQALZI based on severity [see Dosage and Administration (2.3)].

5.3 Neutropenia

BEQALZI can cause serious or severe cytopenias, including neutropenia.

Among 115 patients with MCL who received BEQALZI, new or worsening Grade 3 or 4 decrease in neutrophils developed in 18% (Grade 4, 6%). Febrile neutropenia occurred in 1.7% of patients. Monitor complete blood counts throughout treatment. Based on severity, reduce dose, interrupt, or permanently discontinue BEQALZI [see Dosage and Administration (2.3)].

5.4 Embryo-Fetal Toxicity

Based on findings in animals and its mechanism of action, BEQALZI can cause fetal harm when administered to a pregnant woman. In embryo-fetal development toxicity studies conducted in pregnant mice and rabbits, oral administration of sonrotoclax during the period of organogenesis caused adverse developmental outcomes, including structural abnormalities and altered fetal growth at approximately ≥2 times the clinical exposure based on the area under the concentration-time curve (AUC) at the recommended dose in humans (320 mg/day).

Advise patients of the potential risk to a fetus. Advise females of reproductive potential to use effective contraception during treatment with BEQALZI and for 1 week after the last dose. Advise males with female partners of reproductive potential to use effective contraception during treatment and for 1 week after the last dose [see Use in Specific Populations (8.1, 8.3)].

6.1 Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

Mantle Cell Lymphoma

The safety of BEQALZI was evaluated in 115 adult patients with previously treated MCL in a single-arm, multicenter clinical trial, BGB-11417-201 (NCT05471843) [see Clinical Studies (14.1)]. The trial required prior receipt of anti-CD20–based therapy and a BTK inhibitor. The trial excluded patients on moderate or strong CYP3A inhibitors or strong CYP3A inducers and required an absolute neutrophil count (ANC) ≥1000/mm3; platelets ≥75,000/mm3; creatinine clearance ≥50 mL/min; AST and ALT ≤3 × upper limit of normal (ULN); and serum total bilirubin ≤2 × ULN.

Patients received BEQALZI 320 mg orally once daily following completion of a 4-week ramp-up dosing schedule. Of the 115 patients who received BEQALZI, 52% were exposed for at least 6 months and 34% were exposed for at least 1 year.

Serious adverse reactions were reported in 37% of patients who received BEQALZI, most frequently (≥2%) from pneumonia (10%). Fatal adverse reactions occurred in 4.3% of patients, including from pneumonia (2.6%) and sudden death (1.7%).

Adverse reactions led to dose interruption of BEQALZI in 27% of patients, dose reduction in 0.9%, and permanent discontinuation in 8%. The most common reasons for dose interruption were infections (10%) and neutropenia (5%). The most common adverse reaction leading to treatment discontinuation was infection (1.7%).

Table 7 summarizes select adverse reactions in Study BGB-11417-201, excluding laboratory terms.

7.1 Effects Of Other Drugs On Beqalzi

Strong or Moderate CYP3A Inhibitors

Concomitant use of strong CYP3A inhibitors during the initiation and ramp-up phase with BEQALZI is contraindicated. After the ramp-up phase, reduce the target dose of BEQALZI as in Table 5 [see Dosage and Administration (2.4)].

For dose modifications of sonrotoclax with moderate CYP3A inhibitors, see Dosage and Administration (2.4).

Sonrotoclax is a CYP3A substrate [see Clinical Pharmacology (12.3)]. Concomitant use with strong and moderate CYP3A inhibitors increase sonrotoclax exposure [see Clinical Pharmacology (12.3)], which may increase the risk of BEQALZI adverse reactions.

Strong or Moderate CYP3A Inducers

Avoid concomitant use of strong or moderate CYP3A inducers with BEQALZI.

Sonrotoclax is a CYP3A substrate [see Clinical Pharmacology (12.3)]. Concomitant use with strong CYP3A inducers decreases sonrotoclax exposure [see Clinical Pharmacology (12.3)], which may reduce effectiveness of sonrotoclax.

8.1 Pregnancy

Risk Summary

Based on findings in animals and its mechanism of action [see Clinical Pharmacology (12.1)], BEQALZI can cause embryo-fetal harm when administered to pregnant women. There are no available data on BEQALZI use in pregnant women to evaluate for a drug-associated risk.

In animal reproduction studies, oral administration of sonrotoclax to pregnant mice and rabbits during the period of organogenesis resulted in adverse developmental outcomes, including structural abnormalities and altered fetal growth, at maternal exposures approximately ≥2 times the human exposure (AUC) at the recommended dose of 320 mg daily (see Data). Advise patients of the potential risk to a fetus.

In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively.

Data

Animal Data

Sonrotoclax was administered orally to pregnant mice at doses of 100, 300, and 1000 mg/kg/day during organogenesis (gestation days 6-15). Decreased fetal body weight and crown-rump length were noted at all doses. At the dose of 100 mg/kg/day in mice, the maternal exposure was approximately 8 times the human exposure at the recommended dose of 320 mg once daily.

Sonrotoclax was administered orally to pregnant rabbits at doses of 15, 75, and 300 mg/kg/day during organogenesis (gestation days 6-19). Fetal external (absent or open eye, cleft lip, misshapen mouth, acephalostoma) malformations were noted at 300 mg/kg/day. At the dose of 300 mg/kg/day in rabbits, the maternal exposure was approximately 2 times the human exposure at the recommended dose of 320 mg once daily.

8.2 Lactation

Risk Summary

There are no data on the presence of sonrotoclax or its metabolites in human milk or the effects on the breastfed child or milk production. Because of the potential for serious adverse reactions in a breastfed child, advise women not to breastfeed during treatment with BEQALZI and for 1 week after the last dose.

8.3 Females And Males Of Reproductive Potential

Based on findings in animals and its mechanism of action, BEQALZI can cause fetal harm when administered to pregnant women [see Use in Specific Populations (8.1)].

Pregnancy Testing

Verify pregnancy status in females of reproductive potential prior to initiating BEQALZI.

Contraception

Females

Advise females of reproductive potential to use effective contraception during treatment with BEQALZI and for 1 week after the last dose.

Males

Advise males with female partners of reproductive potential to use effective contraception during treatment with BEQALZI and for 1 week after the last dose.

Infertility

Based on findings in animals, BEQALZI may impair male and female fertility. Fertility findings were reversible in animals [see Nonclinical Toxicology (13.1)].

8.4 Pediatric Use

The safety and effectiveness of BEQALZI in pediatric patients have not been established.

8.5 Geriatric Use

Of the 115 patients with MCL who were treated with BEQALZI, 74 (64%) were 65 years old or older and 26 (23%) were 75 years old or older. Patients aged 65 years and older experienced higher rates of serious adverse reactions (42%) compared to younger patients (29%). Clinical studies of BEQALZI did not include sufficient numbers of patients to determine whether efficacy differs in patients 65 years of age or older compared to younger patients.

8.6 Renal Impairment

No dose adjustments are recommended for patients with mild or moderate renal impairment (estimated glomerular filtration rate (eGFR) ≥30 mL/min). BEQALZI has not been studied in patients with severe renal impairment (eGFR <30 mL/min) [see Clinical Pharmacology (12.3)].

8.7 Hepatic Impairment

No dose adjustments are recommended for patients with mild or moderate hepatic impairment (bilirubin ≤3 × upper limit of normal [ULN] and any aspartate aminotransferase [AST]). BEQALZI has not been studied in patients with severe hepatic impairment (bilirubin >3 × ULN and any AST) [see Clinical Pharmacology (12.3)].

11 Description

BEQALZI tablets contain sonrotoclax, a B-cell lymphoma 2 (BCL-2) inhibitor. The molecular formula of sonrotoclax is C49H59N7O7S and the chemical name is N-[4-({[(1r,4r)-4-hydroxy-4-methylcyclohexyl]methyl}amino)-3-nitrobenzene-1-sulfonyl]-4-(2-{(2S)-2-[2-(propan-2-yl)phenyl]pyrrolidin-1-yl}-7-azaspiro[3.5]nonan-7-yl)-2-[(1H-pyrrolo[2,3- b]pyridin-5-yl)oxy]benzamide.

The molecular weight of sonrotoclax is 890.11 Daltons.

Sonrotoclax has the following structure:

Chemical Structure (Beqalzi 01)

Chemical Structure (Beqalzi 01)

BEQALZI tablets for oral use contain 1, 5, 20, or 80 mg of sonrotoclax. Each tablet contains the following inactive ingredients: anhydrous dibasic calcium phosphate, colloidal silicon dioxide (20 and 80 mg only), croscarmellose sodium, hydroxypropyl methylcellulose acetate succinate, magnesium stearate, microcrystalline cellulose, talc (20 and 80 mg only). The tablet film coating contains FD&C Blue No. 1/brilliant blue FCF aluminum lake, FD&C Red No. 40/allura red ac aluminum lake, polyethylene glycol, polyvinyl alcohol, soy lecithin, talc, and titanium dioxide.

12.1 Mechanism Of Action

Sonrotoclax is an inhibitor of B-cell lymphoma 2 (BCL-2) protein. Overexpression of BCL-2 in various cancers mediates cell survival and has been associated with chemotherapeutic resistance. Sonrotoclax binds to the BCL-2 protein, displacing pro-apoptotic proteins, thereby inducing apoptosis of cells. In nonclinical studies, sonrotoclax demonstrated cytotoxicity in cancer cells overexpressing BCL-2, with a series of intrinsic apoptotic events, including caspase activation.

12.2 Pharmacodynamics

Sonrotoclax exposure-response relationships and the time course of pharmacodynamic response have not been fully characterized.

Cardiac Electrophysiology

Administration of sonrotoclax has the potential to increase the QTc interval. The largest mean increase in QTc interval was 7 ms (upper confidence interval = 14 ms) after administration of sonrotoclax (320 mg once daily) with a low-fat meal in patients with mature B-cell malignancies. There is insufficient information to characterize the QTc effects of sonrotoclax at higher concentrations above recommended dose.

12.3 Pharmacokinetics

Sonrotoclax pharmacokinetics were determined following a single dose or at steady state at the approved recommended dosage of 320 mg once daily and are presented as mean (CV%), unless otherwise specified.

Sonrotoclax area under the plasma drug concentration-time curve (AUC0-24 h) is 3395 (55%) ng∙h/mL and maximum plasma concentration (Cmax) is 353 (49%) ng/mL, following 320 mg once daily with a low-fat meal. Sonrotoclax Cmax and AUC0-tau increase in a less than dose proportional manner over the dosage range of 320 mg to 640 mg (1 to 2 times the highest approved recommended dosage). Limited systemic accumulation of sonrotoclax was observed following repeated administration.

Absorption

The median Tmax of sonrotoclax is 4 hours (ranged from 1 to 8 hours) following 320 mg once daily dosing.

Effect of Food

Sonrotoclax AUC and Cmax increased by approximately 1.5-fold following administration with a low-fat meal (approximately 333-500 kilocalories, 25% fat calories). Sonrotoclax AUC increased by 2-fold and Cmax by 2.4-fold following administration with a high-fat meal (1000 kilocalories, 50% fat).

Distribution

The geometric mean apparent volume of distribution of sonrotoclax is 482 (38%) L. Sonrotoclax plasma protein binding is 99% across a concentration range of 1 to 10 µM. The blood-to-plasma ratio is 0.6 to 0.7.

Elimination

The mean terminal elimination half-life (t½) of sonrotoclax ranges from 4 to 6 hours. The geometric mean apparent oral clearance (CL/F) of sonrotoclax is 94 (62%) L/h.

Metabolism

Sonrotoclax is primarily metabolized by CYP3A and to a lesser extent by CYP2C8 in vitro.

Excretion

After a single radiolabeled sonrotoclax dose of 20 mg to healthy subjects, approximately 86% of the dose was recovered in feces (19.5% unchanged) and 0.28% in urine (0.04% unchanged).

Specific Populations

No clinically meaningful differences in the pharmacokinetics of sonrotoclax were observed based on race, age (27-91 years), sex, weight (37-165 kg), mild to moderate renal impairment (eGFR ≥30 mL/min) or mild to moderate hepatic impairment (bilirubin ≤3 × upper limit of normal (ULN) and any aspartate aminotransferase (AST)). The effect of severe renal impairment (eGFR <30 mL/min) or severe hepatic impairment (total bilirubin >3 × ULN with any AST) on sonrotoclax pharmacokinetics is unknown.

Drug Interactions Studies

Clinical Studies and Model-Informed Approaches

Strong CYP3A inhibitors:

Sonrotoclax AUC increased 11-fold and Cmax increased 4-fold following concomitant administration of itraconazole (strong CYP3A inhibitor and P-gp inhibitor).

Sonrotoclax AUC increased 13-fold and Cmax increased 7-fold following concomitant administration of posaconazole (strong CYP3A inhibitor).

Strong CYP3A inducers: Sonrotoclax AUC decreased to 35% and Cmax to 58% following concomitant use of phenytoin (strong CYP3A inducer).

Other drugs: No clinically significant differences in sonrotoclax pharmacokinetics were observed following concomitant administration with gastric acid reducing agents (proton pump inhibitors, H2-receptor antagonists).

In Vitro Studies

CYP450 Enzymes: Sonrotoclax is not an inhibitor of CYP1A2, CYP2B6, CYP2C8, CYP2C9, CYP2C19, and CYP2D6. Sonrotoclax inhibits CYP3A in vitro, but this is not anticipated to have a clinically meaningful impact. Sonrotoclax is not an inducer of CYP1A2, CYP2B6, or CYP3A4.

Transporters: Sonrotoclax is a substrate of P-gp and BCRP but not OATP1B1 or OATP1B3. Sonrotoclax does not inhibit P-gp, BCRP OATP1B1, OATP1B3, OAT1, OAT3, OCT1, OCT2, MATE1, or MATE2-K.

13.1 Carcinogenesis, Mutagenesis, Impairment Of Fertility

Carcinogenesis

Carcinogenicity studies have not been conducted with sonrotoclax.

Mutagenesis

Sonrotoclax was not mutagenic in a bacterial mutagenicity (Ames) assay and not clastogenic in a chromosome aberration assay in mammalian cells or in an in vivo bone marrow micronucleus assay in mice.

Impairment of Fertility

Fertility studies in animals have not been conducted with sonrotoclax. In a repeat dose, 13-week toxicity study in mice treated with oral administration of sonrotoclax at 20, 100, or 300 mg/kg/day, changes were reported in female reproductive organs at all doses, including the development of ovarian cysts, vaginal mucification, and uterine atrophy. At the dose of 20 mg/kg/day in mice, exposures (AUC) were approximately the same as the human exposure at the recommended dose. In a repeat dose, 13-week toxicity study in dogs treated with oral administration of sonrotoclax at 10, 30, or 100 mg/kg/day, changes were reported in male reproductive organs at all doses, including atrophy, necrosis, and vacuolation of the epididymis with reduced sperm, and atrophy of the prostate and testis. At the dose of 10 mg/kg/day in dogs, exposures were approximately 2 times the human exposure at the recommended dose. Reversibility was noted in both species by the end of the recovery period.

14.1 Mantle Cell Lymphoma

The efficacy of BEQALZI was evaluated in a single-arm, multicenter clinical trial, BGB-11417-201 (NCT05471843). Efficacy was based on 103 adults with relapsed or refractory MCL who previously received anti-CD20–based therapy and a BTK inhibitor. The trial required an ANC ≥1000/mm3, platelets ≥75,000/mm3, and AST and ALT ≤3 × upper limit of normal (ULN). The trial excluded patients with central nervous system lymphoma, prior BCL-2 inhibitor, or an ECOG performance status >2.

Following completion of the ramp-up dosing schedule, patients received BEQALZI at 320 mg orally once daily.

The median age was 68 years (range: 39 to 85 years); 74% were male; 58% were White, 33% Asian, and 3% Black or African American. Most patients (93%) had an ECOG performance of 0 to 1.

Patients had a median of 3 prior lines of therapy (range: 1 to 8), with 89% having at least 2 and 60% having at least 3 prior lines of therapy. All patients were exposed to at least one covalent or noncovalent BTK inhibitor, most commonly ibrutinib (53%), zanubrutinib (27%), and pirtobrutinib (14%). Other prior therapies included lenalidomide in 19%, autologous HSCT in 17%, and CAR-T therapy in 2%. The simplified Mantle Cell Lymphoma International Prognostic Index (sMIPI) score was low in 35%, intermediate in 36%, and high in 29% of patients. High ≥30%) Ki-67 expression was detected in 35% of patients.

Efficacy was established based on overall response rate (ORR) and duration of response (DOR), as assessed by an independent review committee (IRC) using 2014 Lugano criteria. Efficacy results are shown in Table 9. The median time to response was 1.9 months (range: 1.6 to 6.2). The estimated median follow-up for DOR was 11.9 months.

17 Patient Counseling Information

Advise patients to read the FDA-approved patient labeling (Medication Guide).

Tumor Lysis Syndrome

Advise patients of the potential risk of TLS, particularly at treatment initiation, during the ramp-up phase, and with restarting the dose after an interruption, and to immediately report any signs and symptoms associated with this event (fever, chills, nausea, vomiting, confusion, shortness of breath, seizure, irregular heartbeat, decreased urination, unusual tiredness, muscle cramps or twitches) to their healthcare provider (HCP) for evaluation [see Warnings and Precautions (5.1)].

Advise patients to be adequately hydrated when taking BEQALZI to reduce the risk of TLS. The recommended volume is 6 to 8 glasses (approximately 1.5 to 2 liters) of water daily starting 1-2 days before taking BEQALZI, on the day of the first dose, on any day the dose is increased until target dose is reached, and at restart, if applicable [see Dosage and Administration (2.1)].

Advise patients of the importance of keeping scheduled appointments for blood work or other laboratory tests [see Dosage and Administration (2.1)].

Advise patients that it may be necessary to take BEQALZI in the hospital or medical office setting to allow monitoring for TLS.

Serious Infections

Advise patients to contact their healthcare provider immediately if they develop a fever or any signs of infection [see Warnings and Precautions (5.2)].

Neutropenia

Advise patients of the need for periodic monitoring of blood counts [see Warnings and Precautions (5.3)].

Drug Interactions

Advise patients to avoid consuming grapefruit products, Seville oranges, or star fruit during treatment with BEQALZI. BEQALZI may interact with some drugs; therefore, advise patients to inform their healthcare provider of the use of any prescription medication, over-the-counter drugs, vitamins, and herbal products [see Contraindications (4) and Drug Interactions (7.1)].

Embryo-Fetal Toxicity

Advise pregnant women and females of reproductive potential of the potential risk to a fetus. Advise females of reproductive potential to inform their healthcare provider of a known or suspected pregnancy [see Warnings and Precautions (5.4) and Use in Specific Populations (8.1)].

Advise females of reproductive potential to use effective contraception during treatment with BEQALZI and for 1 week after the last dose. Advise males with female partners of reproductive potential to use effective contraception during treatment with BEQALZI and for 1 week after the last dose [see Use in Specific Populations (8.3)].

Lactation

Advise women not to breastfeed during treatment with BEQALZI and for 1 week after the last dose [see Use in Specific Populations (8.2)].

Infertility

Advise males and females of reproductive potential that BEQALZI may impair fertility [see Use in Specific Populations (8.3)].

Administration Instructions

Advise patients to take BEQALZI exactly as prescribed and not to change their dose or to stop taking BEQALZI unless they are told to do so by their healthcare provider. Advise patients to take BEQALZI orally once daily, at approximately the same time each day, according to their healthcare provider's instructions and that the tablets should be swallowed whole with a meal and a glass of water without being broken, chewed, or crushed [see Dosage and Administration (2.5)].

Missed Dose

Advise patients if BEQALZI is missed within 8 hours, to take it as soon as possible with a meal on the same day with a return to the normal schedule the following day. If they miss a dose by more than 8 hours, advise patients to not take the missed dose and resume the usual dosing schedule the next day. Advise patients not to take any additional dose that day if they vomit after taking BEQALZI, and to take the next dose at the usual time the following day [see Dosage and Administration (2.5)].

Restarting After Treatment Interruption

Advise patients to contact their healthcare provider before restarting BEQALZI after stopping treatment. Advise patients that:

  • Their healthcare provider will determine the correct dose based on their previous dose and how long they were off treatment.
  • Depending on how long they were off treatment, they may resume at the same dose where they left off, or they may need to restart at a lower dose.
  • If needed, individual restart packs are available outside of the starter pack for restart dosing as prescribed by their healthcare provider.
    • They may be instructed to resume dosing on Day 1 or Day 4 of the restart pack depending on their prescribed restart dose.
    • If instructed to start on Day 4, they will not use all tablets in the blister pack and should remove and dispose of tablets from Days 1 through 3 in order to avoid confusion or accidental use.
    • They should not use leftover packs from previous treatment without consulting their healthcare provider.

    What is the most important information I should know about BEQALZI?
    BEQALZI can cause serious side effects, including:
    • Tumor lysis syndrome (TLS). TLS is caused by the fast breakdown of cancer cells. TLS can cause kidney failure, the need for dialysis treatment, and can be life-threatening. TLS can happen when you first start treatment with BEQALZI, when your dose is increased, or when you restart BEQALZI after stopping treatment. You will receive other medicines before starting and during treatment with BEQALZI to help reduce your risk of TLS. You may also need to receive intravenous (IV) fluids into your vein. Your healthcare provider will do blood tests to check your risk for TLS before you start treatment and during treatment with BEQALZI. It is important to keep your appointments for blood tests.
      Tell your healthcare provider right away if you get any symptoms of TLS during treatment with BEQALZI, including:
    • nausea
    • vomiting
    • diarrhea
    • muscle cramps, weakness, or twitching
    • fatigue
    • decreased urination
    • swelling in your legs, ankles, or feet
    • numbness or tingling, especially around your mouth or in your hands and feet
    • confusion or difficulty staying alert
    • irregular or fast heart rate
    • seizures
    Drink plenty of water during treatment with BEQALZI to help reduce your risk of getting TLS.
    Drink 6 to 8 glasses (about 1.5 to 2 liters) of water daily:
    • starting 1 to 2 days before your first dose,
    • on the day of your first dose,
    • each time your dose is increased, and
    • if you restart BEQALZI after stopping treatment.
    • Serious infections. BEQALZI can cause death or serious infections. Your healthcare provider will monitor you for signs and symptoms of infection and treat you as needed. Tell your healthcare provider right away if you develop a fever or any signs of an infection.
      • See "What are the possible side effects of BEQALZI?" for more information about side effects.
    What is BEQALZI?
    BEQALZI is a prescription medicine used to treat adults with:
    • mantle cell lymphoma (MCL) that has come back or did not respond to previous treatment, and
    • who have already received at least 2 treatments for their cancer, including a Bruton's tyrosine kinase (BTK) inhibitor medicine.
      • It is not known if BEQALZI is safe and effective in children.
    Who should not take BEQALZI?
    Certain medicines must not be taken when you first start taking BEQALZI and while your dose is being slowly increased because of the increased risk of tumor lysis syndrome (TLS).
    • Tell your healthcare provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements. BEQALZI and other medicines may affect each other causing serious side effects.
    • Do not start new medicines during treatment with BEQALZI without first talking with your healthcare provider.
