Review Date: October 4, 2017
Adcetris is contraindicated with concomitant bleomycin due to pulmonary toxicity (e.g., interstitial infiltration and/or inflammation) [see Adverse Reactions (6.1)].
Effect of Other Drugs on Adcetris
CYP3A4 Inhibitors/Inducers: In vitro data indicate that monomethyl auristatin E (MMAE) is a substrate of CYP3A4/5. MMAE is primarily metabolized by CYP3A[see Clinical Pharmacology (12.3)]. Co-administration of Adcetris with ketoconazole, a potent CYP3A4 inhibitor, increased exposure to MMAE by approximately 34%. Patients who are receiving strong CYP3A4 inhibitors concomitantly with Adcetris should be closely monitored for adverse reactions. Co-administration of Adcetris with rifampin, a potent CYP3A4 inducer, reduced exposure to MMAE by approximately 46%.
P-gp Inhibitors: In vitro data indicate that MMAE is a substrate of the efflux transporter P‑glycoprotein (P-gp). Co-administration of Adcetris with P-gp inhibitors may increase exposure to MMAE. Patients who are receiving P-gp inhibitors concomitantly with Adcetris should be closely monitored for adverse reactions.
Effect of Adcetris on Other Drugs
In vitro data indicate that MMAE is an inhibitor of CYP3A4/5. Co-administration of Adcetris did not affect exposure to midazolam, a CYP3A4 substrate. MMAE does not inhibit other CYP enzymes at relevant clinical concentrations [see Clinical Pharmacology (12.3)]. Adcetris is not expected to alter the exposure to drugs that are metabolized by CYP3A4 enzymes.
Use in specific populations
Adcetris can cause fetal harm based on the findings from animal studies and the drug’s mechanism of action [see Clinical Pharmacology (12.1)]. In animal reproduction studies, administration of brentuximab vedotin to pregnant rats during organogenesis at doses similar to the clinical dose of 1.8 mg/kg every three weeks caused embryo-fetal toxicities, including congenital malformations [see Data]. Consider the benefits and risks of Adcetris and possible risks to the fetus when prescribing Adcetris to a pregnant woman.
In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2–4% and 15–20%, respectively.
In an embryo-fetal developmental study, pregnant rats received 2 intravenous doses of 0.3, 1, 3, or 10 mg/kg brentuximab vedotin during the period of organogenesis (once each on Pregnancy Days 6 and 13). Drug-induced embryo-fetal toxicities were seen mainly in animals treated with 3 and 10 mg/kg of the drug and included increased early resorption (≥99%), post-implantation loss (≥99%), decreased numbers of live fetuses, and external malformations (i.e., umbilical hernias and malrotated hindlimbs). Systemic exposure in animals at the brentuximab vedotin dose of 3 mg/kg is approximately the same exposure in patients with classical HL or sALCL who received the recommended dose of 1.8 mg/kg every three weeks.
There is no information regarding the presence of brentuximab vedotin in human milk, the effects on the breastfed infant, or the effects on milk production. Because of the potential for serious adverse reactions in a breastfed infant from Adcetris, including cytopenias and neurologic or gastrointestinal toxicities, advise patients that breastfeeding is not recommended during Adcetris treatment.
Females and Males of Reproductive Potential
Adcetris can cause fetal harm based on the findings from animal studies and the drug’s mechanism of action [see Use in Specific Populations (8.1),Clinical Pharmacology (12.1)].
Verify the pregnancy status of females of reproductive potential prior to initiating Adcetris therapy.
Advise females of reproductive potential to avoid pregnancy during Adcetris treatment and for at least 6 months after the final dose of Adcetris. Advise females to immediately report pregnancy [see Use in Specific Populations (8.1)].
Adcetris may damage spermatozoa and testicular tissue, resulting in possible genetic abnormalities. Males with female sexual partners of reproductive potential should use effective contraception during Adcetris treatment and for at least 6 months after the final dose of Adcetris [see Nonclinical Toxicology (13.1)].
Based on findings in rats, male fertility may be compromised by treatment with Adcetris [see Nonclinical Toxicology (13.1)].
Safety and effectiveness of Adcetris have not been established in pediatric patients.
Clinical trials of Adcetris did not include sufficient numbers of patients aged 65 and over to determine whether they respond differently from younger patients.
Avoid the use of Adcetris in patients with severe renal impairment (CLcr <30 mL/min) [See Warnings and Precautions (5.6)].
The kidney is a route of excretion for monomethyl auristatin E (MMAE). The pharmacokinetics and safety of brentuximab vedotin and MMAE were evaluated after the administration of 1.2 mg/kg of Adcetris to patients with mild (CLcr >50–80 mL/min; n=4), moderate (CLcr 30–50 mL/min; n=3) and severe (CLcr <30 mL/min; n=3) renal impairment. In patients with severe renal impairment, the rate of Grade 3 or worse adverse reactions was 3/3 (100%) compared to 3/8 (38%) in patients with normal renal function. Additionally, the AUC of MMAE (component of Adcetris) was approximately 2-fold higher in patients with severe renal impairment compared to patients with normal renal function. Due to higher MMAE exposure, ≥Grade 3 adverse reactions may be more frequent in patients with severe renal impairment compared to patients with normal renal function.
Avoid the use of Adcetris in patients with moderate or severe hepatic impairment [See Warnings and Precautions (5.7)].
The liver is a route of clearance for MMAE. The pharmacokinetics and safety of brentuximab vedotin and MMAE were evaluated after the administration of 1.2 mg/kg of Adcetris to patients with mild (Child-Pugh A; n=1), moderate (Child-Pugh B; n=5) and severe (Child-Pugh C; n=1) hepatic impairment. In patients with moderate and severe hepatic impairment, the rate of ≥Grade 3 adverse reactions was 6/6 (100%) compared to 3/8 (38%) in patients with normal hepatic function. Additionally, the AUC of MMAE was approximately 2.2-fold higher in patients with hepatic impairment compared to patients with normal hepatic function.
There is no known antidote for overdosage of Adcetris. In case of overdosage, the patient should be closely monitored for adverse reactions, particularly neutropenia, and supportive treatment should be administered.

Mechanism of Action
CD30-directed antibody-drug conjugate (ADC) consisting of chimeric IgG1 antibody cAC10, specific for human CD30 and the microtubule disrupting agent, monomethyl auristatin E (MMAE, or vedotin); the conjugate binds to cell expressing the CD30 antigen and forms a complex that is internalized within the cell and MMAE is released; MMAE induces cell cycle (G2/M phase) arrest by binding to the tubules and disrupting the cellular microtubule network
Peak Plasma Time: 20-30 min (ADC); 1-3 days (MMAE)
Protein Bound: 68-82% (MMAE)
Vd: 6-10 L (ADC)
Metabolism CYP3A4/5 (MMAE)
MMAE inhibits CYP3A4/5
Half-life: 4-6 days
Excretion: 24% of the total MMAE administered was recovered in both urine and feces over 1 week (72% of which was recovered in the feces)

AU TGA pregnancy category D: Drugs which have caused, are suspected to have caused or may be expected to cause, an increased incidence of human fetal malformations or irreversible damage. These drugs may also have adverse pharmacological effects. Accompanying texts should be consulted for further details. US FDA pregnancy category D: There is positive evidence of human fetal risk based on adverse reaction data from investigational or marketing experience or studies in humans, but potential benefits may warrant use of the drug in pregnant women despite potential risks.
Use is not recommended. AU TGA pregnancy category: D US FDA pregnancy category: D Comments: -This drug can cause fetal harm when administered to a pregnant woman. -Women of childbearing potential should use two methods of effective contraception during treatment with this drug and until 6 months after treatment. -Men being treated with this drug are advised to have sperm samples frozen and stored before treatment. They should not father a child during treatment and for up to 6 months following the last dose. Effects on spermatogenesis cannot be excluded after a 6 month treatment-free period.
