🩺 Clinical
Galcanezumab-gnlm injection is used to help prevent migraine headaches (severe, throbbing headaches that may cause nausea and sensitivity to sound or light). It is also used to treat the symptoms of a cluster headache (severe headaches usually on one side of the head or around one eye). Galcanezumab-gnlm injection is in a class of medications called monoclonal antibodies. It works by blocking the action of a certain natural substance in the body that causes migraine and cluster headaches.

⏳ Availability & biosimilar status
Biologics have no small-molecule generics; biosimilar competition is tracked in the FDA Purple Book.
Why the date isn’t exact: Biosimilar timing can change because patents may be challenged, settled, licensed, added or removed, and litigation can move the real date earlier or later.
🛈 What do these terms mean?
- Biologic patent
- A patent the reference product’s maker has publicly listed. A biosimilar generally can’t launch until these expire — unless they’re invalidated or resolved in a settlement.
- Reference-product exclusivity
- A flat 12 years of FDA market protection from the biologic’s first licensure (the BPCIA). No biosimilar can be licensed before it ends, regardless of patents.
- Interchangeable exclusivity
- The first interchangeable biosimilar can earn a period as the only interchangeable version (pharmacists can substitute it without the prescriber).
- Earliest biosimilar (LOE)
- The latest of all the dates above — the soonest a biosimilar can realistically reach the market. Litigation and settlements can move it earlier.
Biologics have no small-molecule “generics” — competition comes from FDA-licensed biosimilars, tracked in the FDA Purple Book.

⛔ Contraindications ▾
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 )] . EMGALITY is contraindicated in patients with serious hypersensitivity to galcanezumab-gnlm or to any of the excipients. ( 4 )
⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS Hypersensitivity Reactions: If a serious hypersensitivity reaction occurs, discontinue administration of EMGALITY and initiate appropriate therapy. Hypersensitivity reactions can occur days after administration, and may be prolonged. ( 5.1 ) Constipation with Serious Complications: Serious complications of constipation may occur.
( 5.2 ) Hypertension: New-onset or worsening of pre-existing hypertension may occur. ( 5.3 ) Raynaud's Phenomenon: New-onset or worsening of pre-existing Raynaud's phenomenon may occur. ( 5.4 )
5.1Hypersensitivity 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.
5.2Constipation with Serious Complications Constipation with serious complications has been reported following the use of monoclonal antibody CGRP antagonists, including EMGALITY, in the postmarketing setting. There were cases with monoclonal antibody CGRP antagonists that required hospitalization, including cases where surgery was necessary. In a majority of these cases, the onset of constipation was reported after the first dose; however, patients have also presented with constipation later on in treatment.
The monoclonal antibody CGRP antagonist was discontinued in many of the reported cases of constipation with serious complications. Monitor patients treated with EMGALITY for severe constipation and manage as clinically appropriate. The concurrent use of medications that reduce gastrointestinal motility may increase the risk for more severe constipation and the potential for constipation-related complications.
5.3Hypertension Development of hypertension and worsening of pre-existing hypertension have been reported following the use of CGRP antagonists, including EMGALITY, in the postmarketing setting. Some of the patients who developed new-onset hypertension had risk factors for hypertension. There were cases requiring initiation of pharmacological treatment for hypertension and, in some cases, hospitalization.
Hypertension may occur at any time during treatment but was most frequently reported within 7 days of therapy initiation. EMGALITY was discontinued in many of the reported cases. Monitor patients treated with EMGALITY for new-onset hypertension or worsening of pre-existing hypertension, and consider whether discontinuation of EMGALITY is warranted if evaluation fails to establish an alternative etiology or blood pressure is inadequately controlled.
5.4Raynaud's Phenomenon Development of Raynaud’s phenomenon and recurrence or worsening of pre-existing Raynaud’s phenomenon have been reported in the postmarketing setting following the use of CGRP antagonists, including EMGALITY. In reported cases with monoclonal antibody CGRP antagonists, symptom onset occurred after a median of 71 days following dosing. Many of the cases reported serious outcomes, including hospitalizations and disability, generally related to debilitating pain.
In most reported cases, discontinuation of the CGRP antagonist resulted in resolution of symptoms. EMGALITY should be discontinued if signs or symptoms of Raynaud’s phenomenon develop, and patients should be evaluated by a healthcare provider if symptoms do not resolve. Patients with a history of Raynaud’s phenomenon should be monitored for, and informed about the possibility of, worsening or recurrence of signs and symptoms.
🤒 Adverse Reactions ▾
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 )] Constipation with Serious Complications [see Warnings and Precautions ( 5.2 )] Hypertension [see Warnings and Precautions ( 5.3 )] Raynaud's Phenomenon [see Warnings and Precautions ( 5.4 )] The most common adverse reactions (incidence ≥2% and at least 2% greater than placebo) in EMGALITY clinical studies were injection site reactions.
( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Eli Lilly and Company at 1-800-LillyRx (1-800-545-5979) or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.
6.1Clinical 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. Table 1: Adverse Reactions Occurring in Adults with Migraine with an Incidence of at least 2% for EMGALITY and at least 2% Greater than Placebo (up to 6 Months of Treatment) in Studies 1, 2, and 3 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.
Adverse Reaction EMGALITY 120 mg Monthly (N=705) % Placebo Monthly (N=1451) % Injection site reactions a 18 13 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.
6.2Immunogenicity 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,…

8.1Pregnancy Pregnancy Exposure Registry There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to EMGALITY during pregnancy. Healthcare providers are encouraged to register pregnant patients, or pregnant women may enroll themselves in the registry by calling 1-833-464-4724 or by contacting the company at www.migrainepregnancyregistry.com. Risk Summary There are no adequate data on the developmental risk associated with the use of EMGALITY in pregnant women.
Administration of galcanezumab-gnlm to rats and rabbits during the period of organogenesis or to rats throughout pregnancy and lactation at plasma exposures greater than that expected clinically did not result in adverse effects on development (see Animal Data) . 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. The estimated rate of major birth defects (2.2% - 2.9%) and miscarriage (17%) among deliveries to women with migraine are similar to rates reported in women without migraine.
Clinical Considerations Disease-Associated Maternal and/or Embryo/Fetal Risk Published data have suggested that women with migraine may be at increased risk of preeclampsia during pregnancy. Data Animal Data When galcanezumab-gnlm was administered to female rats by subcutaneous injection in two studies (0, 30, or 100 mg/kg; 0 or 250 mg/kg) prior to and during mating and continuing throughout organogenesis, no adverse effects on embryofetal development were observed. The highest dose tested (250 mg/kg) was associated with a plasma exposure (C ave, ss ) 38 or 18 times that in humans at the recommended human dose (RHD) for migraine (120 mg) or episodic cluster headache (300 mg), respectively.
Administration of galcanezumab-gnlm (0, 30, or 100 mg/kg) by subcutaneous injection to pregnant rabbits throughout the period of organogenesis produced no adverse effects on embryofetal development. The higher dose tested was associated with a plasma C ave, ss 64 or 29 times that in humans at 120 mg or 300 mg, respectively. Administration of galcanezumab-gnlm (0, 30, or 250 mg/kg) by subcutaneous injection to rats throughout pregnancy and lactation produced no adverse effects on pre- and postnatal development.
The higher dose tested was associated with a plasma C ave, ss 34 or 16 times that in humans at 120 mg or 300 mg, respectively.
8.2Lactation Risk Summary There are no data on the presence of galcanezumab-gnlm in human milk, the effects on the breastfed infant, or the effects on milk production. The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for EMGALITY and any potential adverse effects on the breastfed infant from EMGALITY or from the underlying maternal condition.
8.4Pediatric Use Safety and effectiveness in pediatric patients have not been established.
8.5Geriatric Use Clinical studies of EMGALITY did not include sufficient numbers of patients aged 65 and over to determine whether they respond differently from younger patients.

🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action Galcanezumab-gnlm is a humanized monoclonal antibody that binds to calcitonin gene-related peptide (CGRP) ligand and blocks its binding to the receptor.
12.2Pharmacodynamics There are no relevant data on the pharmacodynamic effects of galcanezumab-gnlm.
12.3Pharmacokinetics Galcanezumab-gnlm exhibits linear pharmacokinetics and exposure increases proportionally with doses between 1 and 600 mg. A loading dose of 240 mg achieved the serum galcanezumab-gnlm steady-state concentration after the first dose. A dose of 300 mg monthly would achieve steady-state concentration after the fourth dose.
The time to maximum concentration is 5 days, and the elimination half-life is 27 days. There was no difference in pharmacokinetic parameters between healthy volunteers, patients with episodic or chronic migraine, and patients with episodic cluster headache. Absorption Following a subcutaneous dose of galcanezumab-gnlm, the time to maximum concentration was about 5 days.
Injection site location did not significantly influence the absorption of galcanezumab-gnlm. Distribution The apparent volume of distribution (V/F) of galcanezumab-gnlm was
7.3L (34% Inter Individual Variability [IIV]). Metabolism and Elimination Galcanezumab-gnlm is expected to be degraded into small peptides and amino acids via catabolic pathways in the same manner as endogenous IgG. The apparent clearance (CL/F) of galcanezumab-gnlm was 0.008 L/h and the elimination half-life of galcanezumab was approximately 27 days.
Specific Populations Age, Sex, Weight, Race, Ethnicity The pharmacokinetics of galcanezumab-gnlm were not affected by age, sex, race, subtypes of migraine spectrum (episodic or chronic migraine), or headache diagnosis (migraine vs. episodic cluster headache) based on a population pharmacokinetics analysis. Body weight has no clinically relevant effect on the pharmacokinetics of galcanezumab-gnlm. Patients with Renal or Hepatic Impairment Renal and hepatic impairment are not expected to affect the pharmacokinetics of galcanezumab-gnlm.
Population pharmacokinetic analysis of integrated data from the galcanezumab-gnlm clinical studies revealed that creatinine clearance did not affect the pharmacokinetics of galcanezumab-gnlm in patients with mild or moderate renal impairment. Patients with severe renal impairment (creatinine clearance <30 mL/min) have not been studied. Based on a population PK analysis, bilirubin concentration did not significantly influence the CL/F of galcanezumab-gnlm.
No dedicated clinical studies were conducted to evaluate the effect of hepatic impairment or renal impairment on the pharmacokinetics of galcanezumab-gnlm. Drug Interaction Studies P450 Enzymes Galcanezumab-gnlm is not metabolized by cytochrome P450 enzymes; therefore, interactions with concomitant medications that are substrates, inducers, or inhibitors of cytochrome P450 enzymes are unlikely.
