EMGALITY

EMGALITY- galcanezumab injection, solution
Eli Lilly and Company

1 INDICATIONS AND USAGE

1.1 Migraine

EMGALITY is indicated for the preventive treatment of migraine in adults.

1.2 Episodic Cluster Headache

EMGALITY is indicated for the treatment of episodic cluster headache in adults.

2 DOSAGE AND ADMINISTRATION

2.1 Recommended Dosing for Migraine

The recommended dosage of EMGALITY is 240 mg (two consecutive subcutaneous injections of 120 mg each) once as a loading dose, followed by monthly doses of 120 mg injected subcutaneously.

If a dose of EMGALITY is missed, administer as soon as possible. Thereafter, EMGALITY can be scheduled monthly from the date of the last dose.

2.2 Recommended Dosing for Episodic Cluster Headache

The recommended dosage of EMGALITY is 300 mg (three consecutive subcutaneous injections of 100 mg each) at the onset of the cluster period, and then monthly until the end of the cluster period.

If a dose of EMGALITY is missed during a cluster period, administer as soon as possible. Thereafter, EMGALITY can be scheduled monthly from the date of the last dose until the end of the cluster period.

2.3 Important Administration Instructions

EMGALITY is for subcutaneous use only.

EMGALITY is intended for patient self-administration. Prior to use, provide proper training to patients and/or caregivers on how to prepare and administer EMGALITY using the single-dose prefilled pen or single-dose prefilled syringe, including aseptic technique [see How Supplied/Storage and Handling (16.2) and Instructions for Use]:

  • Protect EMGALITY from direct sunlight.
  • Prior to subcutaneous administration, allow EMGALITY to sit at room temperature for 30 minutes. Do not warm by using a heat source such as hot water or a microwave.
  • Do not shake the product.
  • Inspect EMGALITY visually for particulate matter and discoloration prior to administration, whenever solution and container permit [see Dosage Forms and Strengths (3) and How Supplied/Storage and Handling (16.1)]. Do not use EMGALITY if it is cloudy or there are visible particles.
  • Administer EMGALITY in the abdomen, thigh, back of the upper arm, or buttocks subcutaneously. Do not inject into areas where the skin is tender, bruised, red, or hard.
  • Both the prefilled pen and prefilled syringe are single-dose and deliver the entire contents.

3 DOSAGE FORMS AND STRENGTHS

EMGALITY is a sterile clear to opalescent, colorless to slightly yellow to slightly brown solution available as follows:

  • Injection: 120 mg/mL in a single-dose prefilled pen
  • Injection: 120 mg/mL in a single-dose prefilled syringe
  • Injection: 100 mg/mL in a single-dose prefilled syringe

4 CONTRAINDICATIONS

EMGALITY is contraindicated in patients with serious hypersensitivity to galcanezumab-gnlm or to any of the excipients [see Warnings and Precautions (5.1)].

5 WARNINGS AND PRECAUTIONS

5.1 Hypersensitivity Reactions

Hypersensitivity reactions, including dyspnea, urticaria, and rash, have occurred with EMGALITY in clinical studies and the postmarketing setting. Cases of anaphylaxis and angioedema have also been reported in the postmarketing setting. If a serious or severe hypersensitivity reaction occurs, discontinue administration of EMGALITY and initiate appropriate therapy [see Contraindications (4), Adverse Reactions (6.1), and Patient Counseling Information (17)]. Hypersensitivity reactions can occur days after administration and may be prolonged.

6 ADVERSE REACTIONS

The following clinically significant adverse reactions are described elsewhere in the labeling:

  • Hypersensitivity Reactions [see Contraindications (4) and Warnings and Precautions (5.1)]

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 with rates in clinical trials of another drug and may not reflect the rates observed in clinical practice.

Migraine

The safety of EMGALITY has been evaluated in 2586 patients with migraine who received at least one dose of EMGALITY, representing 1487 patient-years of exposure. Of these, 1920 patients were exposed to EMGALITY once monthly for at least 6 months, and 526 patients were exposed for 12 months.

In placebo-controlled clinical studies (Studies 1, 2, and 3), 705 patients received at least one dose of EMGALITY 120 mg once monthly, and 1451 patients received placebo, during 3 months or 6 months of double-blind treatment [see Clinical Studies (14.1)]. Of the EMGALITY-treated patients, approximately 85% were female, 77% were white, and the mean age was 41 years at study entry.

The most common adverse reaction was injection site reactions. In Studies 1, 2, and 3, 1.8% of patients discontinued double-blind treatment because of adverse events. Table 1 summarizes the adverse reactions that occurred within up to 6 months of treatment in the migraine studies.

a Injection site reactions include multiple related adverse event terms, such as injection site pain, injection site reaction, injection site erythema, and injection site pruritus.

Episodic Cluster Headache

EMGALITY was studied for up to 2 months in a placebo-controlled trial in patients with episodic cluster headache (Study 4) [see Clinical Studies (14.2)]. A total of 106 patients were studied (49 on EMGALITY and 57 on placebo). Of the EMGALITY-treated patients, approximately 84% were male, 88% were white, and the mean age was 47 years at study entry. Two EMGALITY-treated patients discontinued double-blind treatment because of adverse events.

Overall, the safety profile observed in patients with episodic cluster headache treated with EMGALITY 300 mg monthly is consistent with the safety profile in migraine patients.

6.2 Immunogenicity

As with all therapeutic proteins, there is potential for immunogenicity. The detection of antibody formation is highly dependent on the sensitivity and specificity of the assay. Additionally, the observed incidence of antibody (including neutralizing antibody) positivity in an assay may be influenced by several factors including assay methodology, sample handling, timing of sample collection, concomitant medications, and underlying disease.

For these reasons, comparison of the incidence of antibodies to galcanezumab-gnlm in the studies described below with the incidence of antibodies in other studies or to other products may be misleading.

The immunogenicity of EMGALITY has been evaluated using an in vitro immunoassay for the detection of binding anti-galcanezumab-gnlm antibodies. For patients whose sera tested positive in the screening immunoassay, an in vitro ligand-binding immunoassay was performed to detect neutralizing antibodies.

In controlled studies with EMGALITY up to 6 months (Study 1, Study 2, and Study 3), the incidence of anti-galcanezumab-gnlm antibody development was 4.8% (33/688) in patients receiving EMGALITY once monthly (32 out of 33 of whom had in vitro neutralizing activity). With 12 months of treatment in an open-label study, up to 12.5% (16/128) of EMGALITY-treated patients developed anti-galcanezumab-gnlm antibodies, most of whom tested positive for neutralizing antibodies.

Although anti-galcanezumab-gnlm antibody development was not found to affect the pharmacokinetics, safety or efficacy of EMGALITY in these patients, the available data are too limited to make definitive conclusions.
