About NEXPLANON^®(etonogestrel implant) 68 mg Radiopaque

Indication
NEXPLANON ^® is indicated for prevention of pregnancy in women of reproductive potential for up to 5 years.

Selected Safety Information

WARNING: RISK OF COMPLICATIONS DUE TO IMPROPER INSERTION and REMOVAL

Improper insertion of NEXPLANON increases the risk of complications.

Proper training prior to first use of NEXPLANON can minimize the risk of improper NEXPLANON insertion.

Because of the risk of complications due to improper insertion and removal NEXPLANON is available only through a restricted program under a Risk Evaluation and Mitigation Strategy (REMS) called the NEXPLANON REMS.

CONTRAINDICATIONS

NEXPLANON should not be used in women who have known or suspected pregnancy; current or past history of thrombosis or thromboembolic disorders; liver tumors, benign or malignant, or active liver disease; undiagnosed abnormal uterine bleeding; known or suspected breast cancer, personal history of breast cancer, or other progestin-sensitive cancer, now or in the past; and/or allergic reaction to any of the components of NEXPLANON.

WARNINGS and PRECAUTIONS
Risk of Complications Due to Improper Insertion and Removal

Complications of Insertion and Removal

NEXPLANON should be inserted subdermally so that it will be palpable after insertion, and this should be confirmed by palpation immediately after insertion. Failure to insert NEXPLANON properly may go unnoticed unless it is palpated immediately after insertion. Undetected failure to insert the implant may lead to an unintended pregnancy. Failure to remove the implant may result in continued effects of etonogestrel, such as compromised fertility, ectopic pregnancy, or persistence or occurrence of a drug-related adverse event.
Complications related to insertion and removal procedures may occur, e.g., pain, paresthesia, bleeding, hematoma, scarring, or infection. If NEXPLANON is inserted deeply (intramuscular or intrafascial), neural or vascular injury may occur.
Postmarketing reports of implants located within the vessels of the arm and the pulmonary artery may have been related to deep insertions or intravascular insertions. Endovascular or surgical procedures may be needed for removal.
Implant removal may be difficult or impossible if the implant is not inserted correctly, is inserted too deeply, not palpable, encased in fibrous tissue, or has migrated. If at any time the implant cannot be palpated, it should be localized, and removal is recommended. When an implant is removed, it is important to remove it in its entirety. Failure to remove the implant may result in continued effects of etonogestrel, such as compromised fertility, ectopic pregnancy, or persistence or occurrence of a drug-related adverse event.

Broken or Bent Implants

Cases of breakage or bending of implants while inserted within a patient's arm have been reported. Cases of migration of a broken implant fragment within the arm have also occurred. These cases may be related to external forces, e.g., manipulation of the implant or contact sports. The release rate of etonogestrel may be slightly increased in a broken or bent implant, based on in vitro data.

NEXPLANON is available only through a restricted program under a REMS.

NEXPLANON REMS

NEXPLANON is only available through a restricted program under a REMS called NEXPLANON REMS because of the risk of complications due to improper insertion and removal.

Notable requirements of the NEXPLANON REMS include the following:

Healthcare providers must be certified with the program by enrolling and completing training on the proper insertion and removal of NEXPLANON prior to first use. Pharmacies must be certified with the program and must only dispense NEXPLANON to certified healthcare providers who dispense NEXPLANON for insertion. Wholesalers and distributors must be registered with the program and must only distribute to certified pharmacies and certified healthcare providers.

Further information is available at and 1-833-697-7367.

Changes in Menstrual Bleeding Patterns

After starting NEXPLANON, women are likely to have changes in their menstrual bleeding pattern. These may include changes in frequency, intensity, or duration. Abnormal bleeding should be evaluated as needed to exclude pathologic conditions or pregnancy. In clinical studies of the non-radiopaque etonogestrel implant, reports of changes in bleeding pattern were the most common reason for stopping treatment (11.1%). Women should be counseled regarding bleeding pattern changes that they may experience.

Ectopic Pregnancies

Be alert to the possibility of an ectopic pregnancy in women using NEXPLANON who become pregnant or complain of lower abdominal pain.

Thrombotic and Other Vascular Events

The use of combination hormonal contraceptives increases the risk of vascular events, including arterial events (strokes and myocardial infarctions) or deep venous thrombotic events (venous thromboembolism, deep venous thrombosis, retinal vein thrombosis, and pulmonary embolism). It is recommended that women with risk factors known to increase the risk of venous and arterial thromboembolism be carefully assessed. There have been postmarketing reports of serious arterial thrombotic and venous thromboembolic events, including cases of pulmonary emboli (some fatal), deep vein thrombosis, myocardial infarction, and strokes, in women using etonogestrel implants. NEXPLANON should be removed in the event of a thrombosis. Due to the risk of thromboembolism associated with pregnancy and immediately following delivery, NEXPLANON should not be used prior to 21 days postpartum. Women with a history of thromboembolic disorders should be made aware of the possibility of a recurrence. Consider removal of the NEXPLANON implant in case of long-term immobilization due to surgery or illness.

Ovarian Cysts

If follicular development occurs, atresia of the follicle is sometimes delayed, and the follicle may continue to grow beyond the size it would attain in a normal cycle. Generally, these enlarged follicles disappear spontaneously. Rarely, surgery may be required.

Carcinoma of the Breast and Reproductive Organs

Some studies suggest that the use of combination hormonal contraceptives might increase the incidence of breast cancer and increase the risk of cervical cancer or intraepithelial neoplasia. Women with a family history of breast cancer or who develop breast nodules should be carefully monitored.

Liver Disease

NEXPLANON should be removed if jaundice occurs.

Elevated Blood Pressure

The NEXPLANON implant should be removed if blood pressure rises significantly and becomes uncontrolled.

Gallbladder Disease

Studies suggest a small increased relative risk of developing gallbladder disease among combination hormonal contraceptive users. It is not known whether a similar risk exists with progestin-only methods like NEXPLANON.

Carbohydrate and Lipid Metabolic Effects

Prediabetic and diabetic women using NEXPLANON should be carefully monitored.

Depressed Mood

Women with a history of depressed mood should be carefully observed. Consideration should be given to removing NEXPLANON in patients who become significantly depressed.

Return to Ovulation

In clinical trials with the non-radiopaque etonogestrel implant (IMPLANON), the etonogestrel levels in blood decreased below sensitivity of the assay by one week after removal of the implant. In addition, pregnancies were observed to occur as early as 7 to 14 days after removal. Therefore, a woman should re-start contraception immediately after removal of the implant if continued contraceptive protection is desired.

Fluid Retention

Hormonal contraceptives may cause some degree of fluid retention. They should be prescribed with caution, and only with careful monitoring, in patients with conditions which might be aggravated by fluid retention. It is unknown if NEXPLANON causes fluid retention.

Contact Lenses

Contact lens wearers who develop visual changes or changes in lens tolerance should be assessed by an ophthalmologist.

ADVERSE REACTIONS
Clinical Trial Experience

The most common adverse reaction causing discontinuation of use of the implant in 3-year clinical trials was change in menstrual bleeding patterns (11.1%). The most common adverse reactions (≥5%) reported in these clinical trials were headache (24.9%), vaginitis (14.5%), weight increase (13.7%), acne (13.5%), breast pain (12.8%), abdominal pain (10.9%), and pharyngitis (10.5%). In a separate clinical trial to assess contraceptive efficacy and safety of NEXPLANON beyond 3 years, up to 5 years, a similar adverse reaction profile was observed as in Years 1 through 3. The most frequently reported adverse reaction >5% was intermenstrual bleeding (5.4%). Changes in menstrual bleeding patterns were the most frequently reported adverse reaction leading to discontinuation occurring in 4.0% of participants.

DRUG INTERACTIONS

Effects of Other Drugs on Hormonal Contraceptives

Substances decreasing the plasma concentrations of hormonal contraceptives and potentially diminishing the efficacy of hormonal contraceptives:

Drugs or herbal products that induce certain enzymes, including cytochrome P450 3A4 (CYP3A4), may decrease the plasma concentrations of hormonal contraceptives and potentially diminish the effectiveness of hormonal contraceptives or increase breakthrough bleeding. Women should use an alternative non-hormonal method of contraception or a back-up method when enzyme inducers are used with hormonal contraceptives, and continue back-up non-hormonal contraception for 28 days after discontinuing the enzyme inducer to ensure contraceptive reliability.

Substances increasing the plasma concentrations of hormonal contraceptives:

Co-administration of certain hormonal contraceptives and strong or moderate CYP3A4 inhibitors may increase the serum concentrations of progestins, including etonogestrel.

Human Immunodeficiency Virus (HIV)/Hepatitis C Virus (HCV) protease inhibitors and non-nucleoside reverse transcriptase inhibitors:

Significant changes (increase or decrease) in the plasma concentrations of progestin have been noted in cases of co-administration with HIV protease inhibitors, HCV protease inhibitors, or non-nucleoside reverse transcriptase inhibitors. These changes may be clinically relevant.

Effects of Hormonal Contraceptives on Other Drugs

Hormonal contraceptives may affect the metabolism of other drugs. Consequently, plasma concentrations may either increase (for example, cyclosporine) or decrease (for example, lamotrigine).

USE IN SPECIFIC POPULATIONS
Pregnancy

Rule out pregnancy before inserting NEXPLANON.

Lactation

Small amounts of contraceptive steroids and/or metabolites, including etonogestrel are present in human milk. No significant adverse effects have been observed in the production or quality of breast milk, or on the physical and psychomotor development of breastfed infants. Hormonal contraceptives, including etonogestrel, can reduce milk production in breastfeeding mothers. This is less likely to occur once breastfeeding is well-established; however, it can occur at any time in some women.

Pediatric Use

The safety and effectiveness of NEXPLANON have been established in women of reproductive potential. Safety and effectiveness of NEXPLANON are expected to be the same in postpubertal adolescents as in adult women. NEXPLANON is not indicated before menarche.

PATIENT COUNSELING INFORMATION

Advise women to contact their healthcare professional immediately if, at any time, they are unable to palpate the implant.
NEXPLANON does not protect against HIV or other STDs.

Before prescribing NEXPLANON, please read the Prescribing Information, including the Boxed Warning. The Patient Information also is available.

About POHERDY^®(pertuzumab-dpzb)

INDICATIONS AND USAGE

Metastatic Breast Cancer (MBC)
POHERDY is indicated for use in combination with trastuzumab and docetaxel for the treatment of adults with HER2-positive metastatic breast cancer who have not received prior anti-HER2 therapy or chemotherapy for metastatic disease.

Early Breast Cancer (EBC)
POHERDY is indicated for use in combination with trastuzumab and chemotherapy for:

The neoadjuvant treatment of adults with HER2-positive, locally advanced, inflammatory, or early stage breast cancer (either greater than 2 cm in diameter or node positive) as part of a complete treatment regimen for early breast cancer The adjuvant treatment of adults with HER2-positive early breast cancer at high risk of recurrence

SELECTED SAFETY INFORMATION

LEFT VENTRICULAR DYSFUNCTION and EMBRYO-FETAL TOXICITY

Pertuzumab products can cause subclinical and clinical cardiac failure manifesting as decreased left ventricular ejection fraction (LVEF) and congestive heart failure (CHF). Evaluate cardiac function prior to and during treatment. Discontinue POHERDY treatment for a confirmed clinically significant decrease in left ventricular function. Exposure to pertuzumab products can cause embryo-fetal death and birth defects. Advise patients of these risks and the need for effective contraception.

CONTRAINDICATIONS
POHERDY is contraindicated in patients with known hypersensitivity to pertuzumab products or to any of its excipients.

WARNINGS AND PRECAUTIONS

Left Ventricular Dysfunction
Pertuzumab products can cause left ventricular dysfunction, including symptomatic heart failure. Decreases in LVEF have been reported with drugs that block HER2 activity, including pertuzumab products.

Assess LVEF prior to initiation of POHERDY and at regular intervals during treatment to ensure that LVEF is within normal limits. If the LVEF declines and has not improved, or has declined further at the subsequent assessment, consider permanent discontinuation of POHERDY and trastuzumab.

In the pertuzumab-treated patients with MBC in CLEOPATRA, left ventricular dysfunction occurred in 4% of patients, and symptomatic left ventricular systolic dysfunction (LVSD) (congestive heart failure) occurred in 1% of patients. Patients who received prior anthracyclines or prior radiotherapy to the chest area may be at higher risk of decreased LVEF or left ventricular dysfunction.

In patients receiving pertuzumab as a neoadjuvant treatment in combination with trastuzumab and docetaxel in NeoSphere, LVEF decline >10% and a drop to 10% and a drop to 360 mg/m² of doxorubicin or its equivalent.

Embryo-Fetal Toxicity
Based on its mechanism of action and findings in animal studies, pertuzumab products can cause fetal harm when administered to a pregnant woman. Pertuzumab products are HER2/neu receptor antagonists. Cases of oligohydramnios and oligohydramnios sequence manifesting as pulmonary hypoplasia, skeletal abnormalities, and neonatal death have been reported with use of another HER2/neu receptor antagonist (trastuzumab) during pregnancy.

Verify the pregnancy status of females of reproductive potential prior to the initiation of POHERDY. Advise pregnant women and females of reproductive potential that exposure to POHERDY in combination with trastuzumab during pregnancy or within 7 months prior to conception can result in fetal harm, including embryo-fetal death or birth defects. Advise females of reproductive potential to use effective contraception during treatment and for 7 months following the last dose of POHERDY in combination with trastuzumab.

Infusion-Related Reactions
Pertuzumab products can cause serious infusion reactions, including fatal events.

In CLEOPATRA, on the first day, when only pertuzumab was administered, infusion-related reactions occurred in 13% of patients, and 30%) with pertuzumab in combination with trastuzumab and docetaxel were diarrhea, alopecia, neutropenia, nausea, fatigue, rash, and peripheral neuropathy.

Neoadjuvant Treatment of Breast Cancer
The most common adverse reactions (>30%) with pertuzumab in combination with trastuzumab and docetaxel were alopecia, diarrhea, nausea, and neutropenia.

The most common adverse reactions (>30%) with pertuzumab in combination with trastuzumab and docetaxel when given for 3 cycles following 3 cycles of FEC were fatigue, alopecia, diarrhea, nausea, vomiting, and neutropenia.

The most common adverse reactions (>30%) with pertuzumab in combination with TCH were fatigue, alopecia, diarrhea, nausea, vomiting, neutropenia, thrombocytopenia, and anemia.

The most common adverse reactions (>30%) with pertuzumab in combination with trastuzumab and paclitaxel when given for 4 cycles following 4 cycles of ddAC were nausea, diarrhea, alopecia, fatigue, constipation, peripheral neuropathy, and headache.

The most common adverse reactions (>30%) with pertuzumab in combination with trastuzumab and docetaxel when given for 4 cycles following 4 cycles of FEC were diarrhea, nausea, alopecia, asthenia, constipation, fatigue, mucosal inflammation, vomiting, myalgia, and anemia.

Adjuvant Treatment of Breast Cancer
The most common adverse reactions (>30%) with pertuzumab in combination with trastuzumab and chemotherapy were diarrhea, nausea, alopecia, fatigue, peripheral neuropathy, and vomiting.

Before prescribing POHERDY, please read the Prescribing Information, including the Boxed Warning about left ventricular dysfunction and embryo-fetal toxicity.

About HADLIMA^®(adalimumab-bwwd) Injection

INDICATIONS AND USAGE

HADLIMA is indicated for the treatment of moderate to severe hidradenitis suppurativa in adult patients.

Uveitis
HADLIMA is indicated for the treatment of non-infectious intermediate, posterior, and panuveitis in adult patients.

SELECTED SAFETY INFORMATION

SERIOUS INFECTIONS
Patients treated with adalimumab products, including HADLIMA, are at increased risk for developing serious infections that may lead to hospitalization or death. Most patients who developed these infections were taking concomitant immunosuppressants such as methotrexate or corticosteroids.

Discontinue HADLIMA if a patient develops a serious infection or sepsis.

Reported infections include:

Active tuberculosis (TB), including reactivation of latent TB. Patients with TB have frequently presented with disseminated or extrapulmonary disease. Test patients for latent TB before HADLIMA use and during therapy. Initiate treatment for latent TB prior to HADLIMA use. Invasive fungal infections, including histoplasmosis, coccidioidomycosis, candidiasis, aspergillosis, blastomycosis, and pneumocystosis. Patients with histoplasmosis or other invasive fungal infections may present with disseminated, rather than localized, disease. Antigen and antibody testing for histoplasmosis may be negative in some patients with active infection. Consider empiric anti-fungal therapy in patients at risk for invasive fungal infections who develop severe systemic illness. Bacterial, viral, and other infections due to opportunistic pathogens, including Legionella and Listeria.

Carefully consider the risks and benefits of treatment with HADLIMA prior to initiating therapy in patients:

with chronic or recurrent infection who have been exposed to TB with a history of opportunistic infection who resided in or traveled in regions where mycoses are endemic with underlying conditions that may predispose them to infection

Monitor patients closely for the development of signs and symptoms of infection during and after treatment with HADLIMA, including the possible development of TB in patients who tested negative for latent TB infection prior to initiating therapy.

Do not start HADLIMA during an active infection, including localized infections. Patients older than 65 years, patients with co-morbid conditions, and/or patients taking concomitant immunosuppressants may be at greater risk of infection. If an infection develops, monitor carefully and initiate appropriate therapy. Drug interactions with biologic products: A higher rate of serious infections has been observed in rheumatoid arthritis (RA) patients treated with rituximab who received subsequent treatment with a TNF blocker. An increased risk of serious infections has been seen with the combination of TNF blockers with anakinra or abatacept, with no demonstrated added benefit in patients with RA. Concomitant administration of HADLIMA with other biologic DMARDs (eg, anakinra or abatacept) or other TNF blockers is not recommended based on the possible increased risk for infections and other potential pharmacological interactions.

MALIGNANCY
Lymphoma and other malignancies, some fatal, have been reported in children and adolescent patients treated with TNF blockers, including adalimumab products. Postmarketing cases of hepatosplenic T-cell lymphoma (HSTCL), a rare type of T-cell lymphoma, have been reported in patients treated with TNF blockers, including adalimumab products. These cases have had a very aggressive disease course and have been fatal. The majority of reported TNF blocker cases have occurred in patients with Crohn's disease or ulcerative colitis and the majority were in adolescent and young adult males. Almost all of these patients had received treatment with azathioprine or 6-mercaptopurine concomitantly with a TNF blocker at or prior to diagnosis. It is uncertain whether the occurrence of HSTCL is related to use of a TNF blocker or a TNF blocker in combination with these other immunosuppressants.

Consider the risks and benefits of HADLIMA treatment prior to initiating or continuing therapy in a patient with known malignancy. In clinical trials, more cases of malignancies were observed among adalimumab-treated subjects compared to control subjects. Non-melanoma skin cancer (NMSC) was reported during clinical trials for adalimumab-treated subjects. Examine all patients, particularly those with a history of prolonged immunosuppressant or psoralen and ultraviolet A (PUVA) therapy, for the presence of NMSC prior to and during treatment with HADLIMA. In adalimumab clinical trials, there was an approximate 3-fold higher rate of lymphoma than expected in the general U.S. population. Patients with chronic inflammatory diseases, particularly those with highly active disease and/or chronic exposure to immunosuppressant therapies, may be at higher risk of lymphoma than the general population, even in the absence of TNF blockers. Postmarketing cases of acute and chronic leukemia were reported with TNF blocker use. Approximately half of the postmarketing cases of malignancies in children, adolescents, and young adults receiving TNF blockers were lymphomas; other cases included rare malignancies associated with immunosuppression and malignancies not usually observed in children and adolescents.

HYPERSENSITIVITY
Anaphylaxis and angioneurotic edema have been reported following adalimumab administration. If a serious allergic reaction occurs, stop HADLIMA and institute appropriate therapy.

HEPATITIS B VIRUS REACTIVATION
Use of TNF blockers, including HADLIMA, may increase the risk of reactivation of hepatitis B virus (HBV) in patients who are chronic carriers. Some cases have been fatal.

Evaluate patients at risk for HBV infection for prior evidence of HBV infection before initiating TNF blocker therapy.

Exercise caution in patients who are carriers of HBV and monitor them during and after HADLIMA treatment.

Discontinue HADLIMA and begin antiviral therapy in patients who develop HBV reactivation. Exercise caution when resuming HADLIMA after HBV treatment.

NEUROLOGIC REACTIONS
TNF blockers, including adalimumab products, have been associated with rare cases of new onset or exacerbation of central nervous system and peripheral demyelinating diseases, including multiple sclerosis, optic neuritis, and Guillain-Barré syndrome.

Exercise caution when considering HADLIMA for patients with these disorders; discontinuation of HADLIMA should be considered if any of these disorders develop.

HEMATOLOGIC REACTIONS
Rare reports of pancytopenia, including aplastic anemia, have been reported with TNF blockers. Medically significant cytopenia has been infrequently reported with adalimumab products.

Consider stopping HADLIMA if significant hematologic abnormalities occur.

CONGESTIVE HEART FAILURE
Worsening and new onset congestive heart failure (CHF) has been reported with TNF blockers. Cases of worsening CHF have been observed with adalimumab products; exercise caution and monitor carefully.

AUTOIMMUNITY
Treatment with adalimumab products may result in the formation of autoantibodies and, rarely, in development of a lupus-like syndrome or autoimmune hepatitis. Discontinue treatment if symptoms of a lupus-like syndrome or autoimmune hepatitis develop.

IMMUNIZATIONS
Patients on HADLIMA should not receive live vaccines.

Pediatric patients, if possible, should be brought up to date with all immunizations before initiating HADLIMA therapy.

Adalimumab is actively transferred across the placenta during the third trimester of pregnancy and may affect immune response in the in utero-exposed infant. The safety of administering live or live-attenuated vaccines in infants exposed to adalimumab products in utero is unknown. Risks and benefits should be considered prior to vaccinating (live or live-attenuated) exposed infants.

ADVERSE REACTIONS
The most common adverse reactions in adalimumab clinical trials (>10%) were: infections (eg, upper respiratory, sinusitis), injection site reactions, headache, and rash.

Before prescribing HADLIMA, please read the Prescribing Information, including the Boxed Warning about serious infections and malignancies. The Medication Guide and Instructions for Use also are available.
