Description for Emrelis

Telisotuzumab vedotin-tllv is a c-Met directed antibody-drug conjugate (ADC) comprised of a humanized immunoglobulin G1 kappa (IgG1κ) monoclonal antibody conjugated to the small molecule microtubule-disrupting agent, monomethyl auristatin E (MMAE), via a protease-cleavable valine-citrulline (vc) linker. The antibody is produced in a mammalian cell line (Chinese hamster ovary) and the drug-linker is produced by chemical synthesis. Each monoclonal antibody molecule carries an average of 3 MMAE molecules. Telisotuzumab vedotin-tllv has an approximate molecular weight of 152 kDa.

EMRELIS (telisotuzumab vedotin-tllv) for injection is a sterile, white to off-white, preservative-free, lyophilized powder in a single-dose vial for reconstitution and dilution prior to intravenous infusion. EMRELIS is supplied as 20 mg per vial or 100 mg per vial and requires reconstitution with Sterile Water for Injection, USP (1.1 mL and 5.2 mL, respectively) to obtain a concentration of 20 mg/mL [see DOSAGE AND ADMINISTRATION]. Following reconstitution, each mL delivers 20 mg of telisotuzumab vedotin-tllv, and histidine (2.33 mg), polysorbate 80 (0.10 mg), sucrose (70.0 mg), and Water for Injection. Hydrochloric acid was added to adjust the pH to 6.0.

Uses for Emrelis

EMRELIS is indicated for the treatment of adult patients with locally advanced or metastatic, non-squamous non-small cell lung cancer (NSCLC) with high c-Met protein overexpression [≥50% of tumor cells with strong (3+) staining], as determined by an FDA-approved test [see DOSAGE AND ADMINISTRATION], who have received a prior systemic therapy.

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

Dosage for Emrelis

Patient Selection

Select patients for treatment with EMRELIS based on the presence of high c-Met protein overexpression [≥50% of tumor cells with strong (3+) staining] in patients with non-squamous NSCLC [see INDICATIONS and Clinical Studies].

Reconstitute and further dilute EMRELIS prior to intravenous infusion.

Reconstitution Of Lyophilized EMRELIS

Before reconstitution, allow the vial to reach room temperature after removal of the vial from storage condition.

Table 4. Reconstitution Volumes

Dose Vial	Volume of Sterile Water for Injection required for reconstitution
20 mg vial	1.1 mL
100 mg vial	5.2 mL

• Calculate the recommended dose based on the patient’s weight to determine the number of vials needed. For patients weighing greater than or equal to 100 kg, use 190 mg dose [see Recommended Dosage]. More than one vial may be needed to achieve the calculated dose.
• Using a sterile syringe, slowly inject Sterile Water for Injection, using the volume provided in Table 4, into the EMRELIS vial containing the lyophilized powder, which has a whole or fragmented cake-like appearance. The reconstituted solution has a concentration of 20 mg/mL EMRELIS.
• Swirl the vial gently until completely dissolved. Do not shake.
• Inspect the reconstituted solution for particulate matter and discoloration. The solution should appear clear to slightly opalescent and colorless to slightly yellow. Discard the vial if the reconstituted solution is discolored, is cloudy, or contains visible particulates.
• Use reconstituted EMRELIS immediately. If not used immediately, store the reconstituted EMRELIS vials in a refrigerator at 2°C to 8°C (36°F to 46°F) for up to 24 hours from the time of reconstitution. Do not freeze.
• Each vial of EMRELIS is intended for one-time use only. Discard any unused drug remaining in the vial.

Dilution In Infusion Bag

• Calculate the required dose volume (mL) of reconstituted EMRELIS solution based on the prescribed dose.
• Withdraw the calculated dose volume (mL) of reconstituted solution from the EMRELIS vial using a sterile syringe. Discard any unused portion remaining in the vial(s).
• Inject the calculated amount of reconstituted solution into 0.9% Sodium Chloride Injection infusion bag so that the final EMRELIS concentration is between 1 mg/mL and 10 mg/mL. Use only 0.9% Sodium Chloride Injection.
• Gently invert the infusion bag to thoroughly mix the solution. Do not shake.
• After preparing the dose for infusion, visually inspect the bag content for particulates and discard if present.
• If not used immediately, the diluted solution can be stored in a refrigerator at 2°C to 8°C (36°F to 46°F) for up to 24 hours and an additional 4 hours at room temperature at 9°C to 30°C (48°F to 86°F) until the end of administration. Do not freeze.

Method Of Administration

If the prepared infusion solution was stored refrigerated at 2°C to 8°C (36°F to 46°F), allow the solution to reach room temperature prior to administration.

• Administer by intravenous infusion over 30 minutes using a dedicated infusion line with a 0.20 or 0.22 micron in-line filter made of polyether sulfone (PES), polyvinylidene fluoride (PVDF), or Polyamide (PA).
• Do not mix EMRELIS with other drugs or administer other drugs through the same intravenous line.

Drug Interactions for Emrelis

Effect Of Other Drugs On EMRELIS

Strong CYP3A Inhibitors

Concomitant use with strong CYP3A inhibitors may increase unconjugated MMAE AUC [see CLINICAL PHARMACOLOGY], which may increase the risk of EMRELIS adverse reactions. Monitor patients for adverse reactions when EMRELIS is given concomitantly with strong CYP3A inhibitors.

Warnings for Emrelis

Included as part of the "PRECAUTIONS" Section

Precautions for Emrelis

Peripheral Neuropathy

EMRELIS can cause peripheral neuropathy, including peripheral sensory neuropathy and peripheral motor neuropathy.

In the safety population [see ADVERSE REACTIONS], peripheral neuropathy occurred in 51% of patients treated with EMRELIS, including Grade 3 in 11%. These adverse reactions included peripheral sensory neuropathy in 45% of patients and peripheral motor neuropathy in 9%. The median time to onset of peripheral neuropathy was 105 days (range: 1 to 472 days). Peripheral neuropathy led to permanent discontinuation of EMRELIS in 13% of patients. The median time to onset of peripheral neuropathy leading to treatment discontinuation was 249 days (range: 57 to 519 days). Of the 7 patients with motor neuropathy ongoing as of their last dose of EMRELIS, 6 had persistent Grade 1 or 2 symptoms 30 days after their last dose.

Monitor patients for signs and symptoms of new or worsening peripheral neuropathy such as hypoesthesia, hyperesthesia, paresthesia, a burning sensation, neuropathic pain, or muscle weakness. Withhold, reduce the dose or permanently discontinue EMRELIS based on severity [see DOSAGE AND ADMINISTRATION].

Interstitial Lung Disease/Pneumonitis

EMRELIS can cause severe, life-threatening, or fatal interstitial lung disease (ILD)/pneumonitis.

In the safety population [see ADVERSE REACTIONS], ILD/pneumonitis occurred in 10% of patients treated with EMRELIS, including Grade 3 in 3% and Grade 4 in 0.6%. There were 3 fatal cases of ILD/pneumonitis in patients who received EMRELIS. The median time to onset of ILD/pneumonitis was 48 days (range: 23 to 85 days). ILD/pneumonitis led to permanent discontinuation of EMRELIS in 7% of patients. The median time to onset of ILD/pneumonitis leading to treatment discontinuation was 46 days (range: 23 to 85 days).

Advise patients to immediately report cough, dyspnea, fever, and/or any new or worsening respiratory symptoms. Monitor patients for signs and symptoms of ILD/pneumonitis. Withhold or permanently discontinue EMRELIS based on severity [see DOSAGE AND ADMINISTRATION].

Ocular Surface Disorders

EMRELIS can cause ocular surface disorders including blurred vision, visual impairment, keratitis, and dry eye.

In the safety population [see ADVERSE REACTIONS], ocular surface disorders occurred in 25% of patients treated with EMRELIS. The most common ocular surface disorders were blurred vision (15%), keratitis (11%), and dry eye (5%). Grade 3 ocular surface disorders occurred in 1.2% of patients [blurred vision (1.2%), and keratitis (0.6%)]. The median time to onset of ocular surface disorders was 47 days (range: 1 to 319 days).

Monitor patients for ocular surface disorders during treatment with EMRELIS. Withhold EMRELIS and refer patients to an eye care professional for an ophthalmic examination and treatment for patients who develop Grade ≥2 ocular toxicity. Withhold or permanently discontinue EMRELIS based on severity [see DOSAGE AND ADMINISTRATION].

Infusion-Related Reactions

EMRELIS can cause infusion-related reactions (IRR); signs and symptoms of IRR include dyspnea, flushing, chills, nausea, chest discomfort, and hypotension. The median time to onset of IRR was 28 days (range: 1 to 43 days).

In the safety population, [see ADVERSE REACTIONS], IRR occurred in 3% of patients treated with EMRELIS including Grade 3 in 1.2% and Grade 4 in 0.6%. IRR led to permanent discontinuation of EMRELIS in 0.6% of patients.

Monitor patients for signs and symptoms of infusion reactions during EMRELIS infusion. Withhold, reduce the rate of infusion, or permanently discontinue EMRELIS based on severity [see DOSAGE AND ADMINISTRATION]. For patients who experience IRR, administer premedications prior to subsequent infusions.

Embryo-Fetal Toxicity

Based on the mechanism of action and findings in animals, EMRELIS can cause fetal harm when administered to a pregnant woman. The small molecule component of EMRELIS, MMAE, administered to rats caused adverse developmental outcomes, including embryo-fetal mortality and structural abnormalities, at exposures similar to those occurring clinically at the recommended dose.

Advise patients of the potential risk to a fetus. Advise females of reproductive potential to use effective contraception during treatment with EMRELIS and for 2 months after the last dose. Advise male patients with female partners of reproductive potential to use effective contraception during treatment with EMRELIS and for 4 months after the last dose [see Use In Specific Populations and CLINICAL PHARMACOLOGY].

Patient Counseling Information

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

Peripheral Neuropathy

Advise patients that EMRELIS can cause peripheral neuropathy. Advise patients to report to their healthcare provider any new or worsening numbness or tingling of the hands or feet or any muscle weakness [see WARNINGS AND PRECAUTIONS].

ILD/Pneumonitis

Advise patients that EMRELIS can cause ILD/pneumonitis. Advise patients to immediately report to their healthcare provider any new or worsening respiratory symptoms [see WARNINGS AND PRECAUTIONS].

Ocular Surface Disorders

Advise patients that EMRELIS can cause ocular surface disorders. Advise patients to contact their healthcare provider any new or worsening ocular problems or vision changes [see WARNINGS AND PRECAUTIONS].

Advise males and females of reproductive potential that EMRELIS may impair fertility [see Nonclinical Toxicology].

Nonclinical Toxicology

Carcinogenesis, Mutagenesis, Impairment Of Fertility

Carcinogenesis

Carcinogenicity studies in animals have not been performed with telisotuzumab vedotin-tllv or the small molecule MMAE.

Mutagenesis

MMAE was positive for genotoxicity in the in vivo rat bone marrow micronucleus study through an aneugenic mechanism. MMAE was not mutagenic in the bacterial reverse mutation (Ames) assay or the L5178Y TK+/- mouse lymphoma forward mutation assay.

Impairment Of Fertility

Fertility studies with telisotuzumab vedotin-tllv or MMAE have not been conducted. However, results of repeat-dose toxicity studies in rats and monkeys indicate the potential for telisotuzumab vedotin-tllv to impair male and female reproductive function and fertility.

In a 2-week repeat-dose toxicology study in rats, telisotuzumab vedotin-tllv administered at doses ≥6 mg/kg (≥12 times the human exposure [AUC] at the recommended dose) resulted in decreased number/degeneration of germ cells in the testes largely due to loss of spermatogonia. The reversibility of these findings was not assessed.

In a 4-week repeat-dose toxicology study in sexually immature monkeys, telisotuzumab vedotin-tllv administered at doses ≥3 mg/kg (≥4 times the human exposure [AUC] at the recommended dose) resulted in degeneration of granulosa cells and decreased number of tertiary follicles in the ovaries and degeneration/necrosis of endometrial glands in the uterus. There was evidence of reversibility after an 8-week recovery period.

Use In Specific Populations

Pregnancy

Risk Summary

Based on the mechanism of action and findings in animals, EMRELIS can cause fetal harm when administered to a pregnant woman [see CLINICAL PHARMACOLOGY]. There are no available human data on EMRELIS use in pregnant women to inform a drug-associated risk. In an animal reproduction study, administration of the small molecule component of EMRELIS, MMAE, to pregnant rats during organogenesis resulted in embryo-fetal mortality and structural abnormalities at exposures similar to the clinical exposure at the recommended dose [see Data]. Advise patients of the potential risks 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

No embryo-fetal development studies in animals have been performed with telisotuzumab vedotin-tllv. In an embryo-fetal development study in pregnant rats, administration of two intravenous doses of MMAE, the small molecule component of EMRELIS, on gestational days 6 and 13 caused embryo-fetal mortality and structural abnormalities, including protruding tongue, agnathia, malrotated limbs, and gastroschisis compared to controls at a dose of 0.2 mg/kg (approximately 2 times the human area under the curve [AUC] at the recommended dose).

Lactation

Risk Summary

There are no data on the presence of telisotuzumab vedotin-tllv or MMAE in human milk, the effects on the breastfed child, or the effects on milk production. Because of the potential for serious adverse reactions in a breastfed child, advise lactating women not to breastfeed during treatment with EMRELIS and for 1 month after the last dose.

Females And Males Of Reproductive Potential

EMRELIS can cause fetal harm when administered to a pregnant woman [see Pregnancy].

Pregnancy Testing

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

Contraception

Females

Advise females of reproductive potential to use effective contraception during treatment with EMRELIS and for 2 months after the last dose.

Males

Based on genotoxicity findings, advise male patients with female partners of reproductive potential to use effective contraception during treatment with EMRELIS and for 4 months after the last dose.

Infertility

Females

Based on findings in animal studies with MMAE-containing antibody-drug conjugates (ADCs), EMRELIS may impair female fertility. The effect on fertility is reversible [see Nonclinical Toxicology].

Males

Based on findings from animal studies, EMRELIS may impair male fertility. The reversibility of this effect is unknown [see Nonclinical Toxicology].

Pediatric Use

Safety and effectiveness of EMRELIS have not been established in pediatric patients.

Geriatric Use

Of the 168 patients with previously treated EGFR wild-type non-squamous NSCLC with c-Met protein overexpression treated with EMRELIS in LUMINOSITY, 50% were ≥65 years of age and 12% were ≥75 years of age. No overall differences in safety or effectiveness were observed between older and younger patients.

Hepatic Impairment

Avoid use of EMRELIS in patients with moderate or severe hepatic impairment (total bilirubin >1.5 x ULN and any AST).

Patients with moderate or severe hepatic impairment are likely to have increased exposure to MMAE, which may increase the risk of adverse reactions. EMRELIS has not been studied in patients with moderate or severe hepatic impairment.

No dosage adjustment is recommended for patients with mild hepatic impairment (total bilirubin ≤ULN and AST >ULN or total bilirubin >ULN and ≤1.5 x ULN and any AST) [see CLINICAL PHARMACOLOGY].

Overdose Information for Emrelis

Contraindications for Emrelis

None.

Clinical Pharmacology for Emrelis

Mechanism Of Action

Telisotuzumab vedotin-tllv is a c-Met-directed antibody drug conjugate (ADC). The antibody is a humanized IgG1κ directed against c-Met, the cell surface receptor for hepatocyte growth factor. The small molecule, MMAE, is a microtubule-disrupting agent, attached to the antibody via a protease cleavable linker. Following binding to c-Met-expressing cells, telisotuzumab vedotin-tllv undergoes internalization and intracellular cleavage of MMAE. MMAE disrupts the microtubule network of actively dividing cells, subsequently inducing cell cycle arrest and apoptotic cell death. Telisotuzumab vedotin-tllv exhibited antitumor activity in xenograft models of NSCLC.

Pharmacodynamics

Exposure Response Relationships

Exposure-response relationships for efficacy and time course of pharmacodynamic response have not been fully characterized.

Higher telisotuzumab vedotin-tllv exposure was associated with increased rates of Grade 3 peripheral neuropathy, and Grades 2 and 3 ocular surface disorders. Higher unconjugated MMAE exposure was associated with increased rates of Grade ≥3 adverse reactions and fatal adverse reactions.

Cardiac Electrophysiology

There is insufficient information to characterize the effect of telisotuzumab vedotin-tllv on the QT interval.

Pharmacokinetics

The exposure parameters of telisotuzumab vedotin-tllv (ADC) and unconjugated MMAE (cytotoxic component of EMRELIS) are summarized in Table 7. The plasma exposure of the ADC and unconjugated MMAE increased proportionally over a dose range of 1.2 to 3.3 mg/kg (0.64 to 1.7 times the approved recommended dose). ADC time to maximum plasma concentrations (Tmax) occurs at the end of intravenous infusion while MMAE Tmax occurs approximately 5 days after EMRELIS administration. Minimal accumulation of the ADC or MMAE occurs.

Table 7. Exposure Parameters of Telisotuzumab Vedotin-tllv (ADC) and Unconjugated MMAE at EMRELIS 1.9 mg/kg Every 2 Weeks

	ADC	Unconjugated MMAE
Cmax	29 (43) µg/mL	2.2 (53) ng/mL
AUC0-tau	2,130 (55) µg·hr/mL	405 (64) ng·hr/mL
Cmax = maximum concentration AUC0-tau = area under the concentration-time curve from time zero to 14 days (2 weeks)

Distribution

The estimated volume of distribution is 3.4 L (16.5%CV) for telisotuzumab vedotin-tllv.

MMAE plasma protein binding ranges from 68% to 82% in vitro.

Elimination

The elimination half-life is approximately 3 days for the ADC and approximately 4 days for MMAE. The estimated clearance (CL) is 1.3 L/day (31.5%CV) for the ADC and 76 L/day (52.1%CV) for MMAE.

Metabolism

Telisotuzumab vedotin-tllv catabolism has not been studied in humans; however, it is expected to undergo catabolism to small peptides, amino acids, unconjugated MMAE, and unconjugated MMAE-related catabolites. MMAE is metabolized primarily by CYP3A4.

Specific Populations

No clinically significant differences in the pharmacokinetics of the ADC or unconjugated MMAE were observed based on age (30 to 87 years), sex, race (65% White, 32% Asian, and 3% Black), body weight (34 to 144 kg), mild or moderate renal impairment (CLcr 30 to 89 mL/min, estimated by Cockcroft-Gault), or mild hepatic impairment (total bilirubin ≤ULN and AST >ULN or total bilirubin >ULN and ≤1.5 x ULN and any AST).

The effect of severe renal impairment (CLcr <30 mL/min), end-stage renal disease with or without dialysis, or moderate to severe hepatic impairment (total bilirubin >1.5 × ULN and any AST) on the pharmacokinetics of telisotuzumab vedotin-tllv or unconjugated MMAE is unknown.

Drug Interaction Studies

Clinical Studies And Model-Informed Approaches

No clinical studies have evaluated the potential for drug-drug interactions.

Strong CYP3A4 Inhibitor

MMAE AUC is predicted to increase by 1.4-fold following concomitant administration of EMRELIS with ketoconazole (a strong CYP3A inhibitor).

Strong CYP3A4 Inducer

MMAE AUC is predicted to decrease by 70% following concomitant administration of EMRELIS with rifampicin (a strong CYP3A inducer).

Sensitive CYP3A Substrate

No clinically significant difference in the pharmacokinetics of midazolam (a sensitive CYP3A substrate) is predicted when used concomitantly with EMRELIS.

In Vitro Studies

Cytochrome P450 (CYP) Enzymes

MMAE is a substrate and an inhibitor of CYP3A4/5.

Transporter Systems

MMAE is a substrate of P-glycoprotein (P-gp).

Immunogenicity

The observed incidence of anti-drug antibodies is highly dependent on the sensitivity and specificity of the assay. Differences in assay methods preclude meaningful comparisons of the incidence of anti-drug antibodies in the study described below with the incidence of anti-drug antibodies in other studies, including those of EMRELIS or of other telisotuzumab products.

Following administration of EMRELIS in LUMINOSITY, 22% (60/269) of patients tested positive for treatment-emergent antibodies against telisotuzumab vedotin-tllv at one or more post-baseline time points. Of those who tested positive for anti-drug antibody, neutralizing antibodies were detected in 38% (23/60) of patients. Development of anti-drug antibodies and neutralizing antibodies resulted in a 17% decrease in clearance of telisotuzumab vedotin-tllv. There are insufficient data to assess whether the observed anti-telisotuzumab vedotin-tllv antibody-associated pharmacokinetic changes affect the safety and effectiveness of EMRELIS.

Clinical Studies

Previously Treated EGFR Wild-Type Non-squamous NSCLC with High c-Met Protein Overexpression

LUMINOSITY

The efficacy of EMRELIS was evaluated in the LUMINOSITY study (NCT03539536), a multicenter, open-label, single-arm, multi-cohort clinical trial. Eligible patients were required to have locally advanced or metastatic NSCLC with c-Met protein overexpression and treatment with prior systemic therapy (including no more than one line of prior chemotherapy) in the locally advanced or metastatic setting. The study excluded patients who had received radiation therapy to the lungs <6 months prior to enrollment and patients who had a history of ILD/pneumonitis requiring treatment with steroids or ILD/pneumonitis within 3 months of the first dose.

Patients received EMRELIS at 1.9 mg/kg intravenously every 2 weeks until disease progression or unacceptable toxicity. The major efficacy outcome measure was overall response rate (ORR) according to Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 as assessed by a blinded independent central review (BICR). An additional efficacy outcome measure was duration of response (DOR) by BICR.

The efficacy population included 84 patients with non-squamous, EGFR wild-type NSCLC with high c-Met protein overexpression who had received prior systemic therapy. High c-Met protein overexpression was defined as ≥50% of tumor cells with strong (3+) membrane staining on archival or recent tissue samples by immunohistochemistry (IHC) and was determined by prospective testing at a central laboratory prior to enrollment using the MET (SP44) clinical trial assay (CTA). Of the 84 patients with high c-Met protein overexpression identified by central testing using the CTA, tissue samples from 38/84 (45%) patients were tested retrospectively using the VENTANA MET (SP44) RxDx assay. One sample was unevaluable. Of the 37 samples retested and evaluable, 32 (87%) samples were confirmed to have high c-Met protein overexpression, defined as ≥50% of tumor cells with strong (3+) membrane and/or cytoplasmic staining.

The median age was 64 years (range: 38 to 83 years); 75% were male; 61% were White, 1.2% were Black or African American, 38% were Asian; none were of Hispanic or Latino ethnicity. Twenty-five percent had an Eastern Cooperative Oncology Group Performance Status (ECOG PS) of 0 and 74% had ECOG PS of 1; 19% were never smokers, 68% were former smokers, and 13% were current smokers; 99% had Stage IV disease; and 19% of patients had previously treated brain metastases. The median number of lines of prior therapies was 1 (range 1 - 3); 73% of patients had one line, 24% had two lines, and 3.6% had three lines of prior systemic therapy; 96% of patients had prior platinum therapy, 82% had prior immunotherapy (anti-PD-1/PD-L1), 6% had prior targeted therapy, and 3.6% had prior MET tyrosine kinase inhibitor therapy.

Efficacy results are summarized in Table 8.

What is the most important information I should know about EMRELIS?

EMRELIS can cause serious side effects, including:

• Nerve problems in your hands or feet (peripheral neuropathy). Nerve problems are common during treatment with EMRELIS and can also be severe. Tell your healthcare provider if you develop any new or worsening signs or symptoms of nerve problems, including:
  • numbness
  • tingling
  • burning sensation
  • pain or discomfort
  • muscle weakness
  • difficulty walking
• Lung problems. EMRELIS can cause lung problems that may be severe, life-threatening or that may lead to death. Tell your healthcare provider right away if you develop new or worsening lung symptoms, including:
  • cough
  • trouble breathing or shortness of breath
  • fever
  • wheezing
• Eye problems. Your healthcare provider may send you to an eye care professional to check your eyes if you develop eye problems. Tell your healthcare provider right away if you develop any new or worsening eye problems or vision changes, including:
  • blurred vision
  • dry eyes
  • sensitivity to light
  • eye pain or swelling
  • eye redness
• Infusion-related reactions. EMRELIS can cause infusion reactions that can be severe or life-threatening. Tell your healthcare provider right away if you develop any signs and symptoms of infusion reactions, including:
