USE IN SPECIFIC POPULATIONS
See 17 for PATIENT COUNSELING INFORMATION and FDA-approved patient labeling. Revised: 11/2018 |
EGRIFTA is indicated for the reduction of excess abdominal fat in HIV-infected adult patients with lipodystrophy.
Limitations of Use:
EGRIFTA for injection is supplied in a single-dose 2 mg vial as a white to off-white lyophilized powder and a diluent of 10 mL of Sterile Water for Injection, USP.
EGRIFTA is contraindicated in patients with:
New Malignancy
Carefully consider the decision to start treatment with EGRIFTA based on the increased background risk of malignancies in HIV-positive patients.
Active Malignancy
EGRIFTA induces the release of endogenous growth hormone (GH), a known growth factor. Do not treat patients with active malignancy with EGRIFTA [see Contraindications (4)].
History of Malignancy
For patients with a history of non-malignant neoplasms, initiate EGRIFTA therapy after careful evaluation of the potential benefit of treatment. For patients with a history of treated and stable malignancies, initiate EGRIFTA therapy only after careful evaluation of the potential benefit of treatment relative to the risk of re-activation of the underlying malignancy. Discontinue EGRIFTA if there is any evidence of recurrent malignancy.
EGRIFTA stimulates GH production and increases serum IGF-1, a growth factor. The effects of prolonged elevations in IGF-1 levels are unknown. Monitor IGF-1 levels during EGRIFTA therapy. Consider discontinuing EGRIFTA in patients with persistent elevations of IGF-1 levels (e.g., >3 SDS), particularly if the efficacy response is not robust.
Among patients who received EGRIFTA for 26 weeks, 47% had IGF-1 levels greater than 2 standard deviation scores (SDS), and 36% had SDS >3, with this effect seen as early as 13 weeks of treatment. Among those patients who remained on EGRIFTA for a total of 52 weeks, at the end of treatment 34% had IGF-1 SDS >2 and 23% had IGF-1 SDS >3.
Fluid retention may occur during EGRIFTA therapy and is thought to be related to the induction of GH secretion. This manifests as increased tissue turgor and musculoskeletal discomfort resulting in adverse reactions (e.g. edema, arthralgia, carpal tunnel syndrome) which are either transient or resolve with discontinuation of treatment.
EGRIFTA treatment can result in glucose intolerance. During clinical trials, the percentages of patients with elevated HbA1c (≥ 6.5%) from baseline to Week 26 were 5% and 1% in the EGRIFTA and placebo groups, respectively. An increased risk of developing diabetes with EGRIFTA (HbA1c level ≥ 6.5%) relative to placebo was observed [intent-to-treat hazard odds ratio of 3.3 (CI 1.4, 9.6)].
Evaluate glucose status prior to initiating EGRIFTA. Monitor all patients treated with EGRIFTA periodically to diagnose those who develop impaired glucose tolerance or diabetes. If patients treated with EGRIFTA develop glucose intolerance or diabetes, consider discontinuing EGRIFTA in patients who do not show a clear efficacy response.
EGRIFTA increases IGF-1, monitor patients with diabetes who are receiving treatment with EGRIFTA at regular intervals for potential development or worsening of retinopathy.
Hypersensitivity reactions occurred in 4% of patients treated with EGRIFTA in clinical trials. Reactions included pruritus, erythema, flushing, urticaria, and rash. In cases of suspected hypersensitivity reactions, advise patients to seek prompt medical attention and immediately discontinue treatment with EGRIFTA.
EGRIFTA may cause injection site reactions, including injection site erythema, pruritus, pain, irritation, and bruising. The incidence of injection site reactions was 25% in EGRIFTA-treated patients and 14% in placebo-treated patients during the first 26 weeks of treatment in clinical trials. Rotate injection sites to different areas of the abdomen to decrease injection site reactions [see Dosage and Administration (2.1)].
Increased mortality in patients with acute critical illness due to complications following open heart surgery, abdominal surgery or multiple accidental trauma, or those with acute respiratory failure has been reported after treatment with pharmacologic amounts of growth hormone. EGRIFTA is a Growth Hormone-Releasing Hormone (GHRH) and since EGRIFTA stimulates growth hormone production, consider discontinuing EGRIFTA in critically ill patients.
The following important adverse reactions are also described elsewhere in the labeling:
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
The safety of the EGRIFTA 2 mg/vial formulation has been established based on clinical trials conducted with the EGRIFTA 1 mg/vial formulation. Adverse reactions for the 1.4 mg dose (2 mg/vial formulation) of EGRIFTA are expected to be similar to those observed with the 2 mg dose (1 mg/vial formulation) of EGRIFTA [see Clinical Pharmacology (12.3)].
Seven hundred and forty HIV-infected patients with lipodystrophy and excess abdominal fat were treated with EGRIFTA in clinical trials; of these, 543 received EGRIFTA during the initial 26-week placebo-controlled phase.
The most commonly reported adverse reactions were hypersensitivity reactions (e.g., rash, urticaria), edema-related reactions (e.g., arthralgia, extremity pain, peripheral edema, carpal tunnel syndrome), hyperglycemia, and injection site reactions (injection site erythema, pruritus, pain, urticaria, irritation, swelling, hemorrhage).
Adverse reactons that occurred more frequently with EGRIFTA relative to placebo and had an incidence ≥1% during the first 26 weeks across all studies are presented in Table 1.
* Injection site reaction includes: Injection site erythema, Injection site pruritus, Injection site rash, Injection site urticaria, Injection site pain, Injection site swelling, Injection site irritation, Injection site hemorrhage. |

In the EGRIFTA clinical trials, mean baseline HbA1c was 5.3% among patients in both the EGRIFTA and placebo groups. Patients receiving EGRIFTA had an increased risk of developing diabetes (HbA1c level ≥ 6.5%) compared with placebo (5% vs. 1%), with a hazard ratio of 3.3 (CI 1.4, 9.6).
As with all therapeutic proteins and peptides, there is a potential for development of anti- EGRIFTA antibodies. The observed incidence of antibody positivity in an assay is highly dependent on several factors, including assay sensitivity and specificity, methodology, sample handling, timing of sample collection, concomitant medication and underlying disease. For these reasons, comparison of the incidence of antibodies to EGRIFTA with the incidence of antibodies to other products may be misleading.
In the clinical trials with the EGRIFTA 1 mg/vial formulation, anti-tesamorelin IgG antibodies were detected in 50% of patients treated with EGRIFTA for 26 weeks and 47% of patients who received EGRIFTA for 52 weeks. In the subset of patients with hypersensitivity reactions, anti-tesamorelin IgG antibodies were detected in 85%. Cross-reactivity to endogenous Growth Hormone-Releasing Hormone (GHRH) was observed in approximately 60% of patients who developed anti-tesamorelin antibodies. Patients with and without anti-tesamorelin IgG antibodies had similar mean reductions in visceral adipose tissue (VAT) and IGF-1 response. In a group of patients who had antibodies to tesamorelin after 26 weeks of treatment (56%) and were re-assessed 6 months later, after stopping EGRIFTA treatment, 18% were still antibody positive.
Neutralizing antibodies to tesamorelin and hGHRH were detected in vitro at Week 52 in 10% and 5% of EGRIFTA-treated patients, respectively. Changes in VAT and IGF-1 levels in patients with or without in vitro neutralizing antibodies were comparable.
Co-administration of EGRIFTA with simvastatin, a CYP3A substrate, showed that EGRIFTA had no significant impact on the pharmacokinetics profiles of simvastatin in healthy subjects [see Clinical Pharmacology (12.3)].
EGRIFTA stimulates GH production. Published data indicate that GH may modulate cytochrome P450 (CYP450) mediated antipyrine clearance. These data suggest that GH may alter the clearance of compounds known to be metabolized by CYP450 liver enzymes (e.g., corticosteroids, sex steroids, anticonvulsants, cyclosporine). Monitor patients for potential interactions when administering EGRIFTA in combination with other drugs known to be metabolized by CYP450 liver enzymes.
GH inhibits 11β-hydroxysteroid dehydrogenase type 1 (11βHSD-1), a microsomal enzyme required for conversion of cortisone to its active metabolite, cortisol, in hepatic and adipose tissue. EGRIFTA stimulates GH production, therefore, patients receiving glucocorticoid replacement for previously diagnosed hypoadrenalism may require an increase in maintenance or stress doses following initiation of EGRIFTA. Patients treated with cortisone acetate and prednisone may be affected more than others because conversion of these drugs to their biologically active metabolites is dependent on the activity of 11βHSD-1.
Risk Summary
EGRIFTA is contraindicated in pregnant women because modifying visceral adipose tissue offers no benefit in pregnant women and could result in fetal harm [see Clinical Considerations and Contraindications (4)]. Administration of tesamorelin acetate to rats during organogenesis resulted in hydrocephaly in offspring at a dose of approximately two and four times the clinical dose, based on measured drug exposure (AUC). If EGRIFTA is used during pregnancy, or if the patient becomes pregnant while taking this drug, discontinue EGRIFTA.
The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. 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.
Clinical Considerations
Disease-associated maternal and/or embryo/fetal risk
During pregnancy, visceral adipose tissue increases due to normal metabolic and hormonal changes. Modifying pregnancy-associated physiologic changes in visceral adipose tissue with EGRIFTA offers no known benefit and could result in fetal harm.
Data
Animal Data
Tesamorelin acetate administration to rats during organogenesis and lactation resulted in hydrocephaly in offspring at a dose of approximately two and four times the clinical dose, respectively, based on measured drug exposure (AUC). Actual animal dose was 1.2 mg/kg. During organogenesis, lower doses approximately 0.1 to 1 times the clinical dose caused delayed skull ossification in rats. Actual animal doses were 0.1 to 0.6 mg/kg. No adverse developmental effects occurred in rabbits using doses up to approximately 500 times the clinical dose.
Risk Summary
The Centers for Disease Control and Prevention recommend that HIV-infected mothers in the United States not breastfeed their infants to avoid risking postnatal transmission of HIV-1 infection. There are no data on the presence of tesamorelin in human milk, the effects on the breastfed child, or the effects on milk production. Because of both the potential for (1) HIV-1 infection transmission (in HIV-negative infants), (2) developing viral resistance (in HIV-positive patients), and (3) any possible adverse effects of EGRIFTA, mothers should not breastfeed if they receive EGRIFTA.
The safety and effectiveness of EGRIFTA in pediatric patients have not been established.
In pediatric patients with open epiphyses, treatment with EGRIFTA may result in linear growth acceleration and excessive growth. EGRIFTA is not indicated for use in pediatric patients with open or closed epiphyses.
EGRIFTA contains tesamorelin (as the acetate salt), a human growth hormone-releasing factor (GRF) analog. The peptide precursor of tesamorelin acetate is produced synthetically and is comprised of the 44 amino acid sequence of human GRF. Tesamorelin acetate is made by attaching a hexenoyl moiety, a C6 chain with a double bond at position 3, to the tyrosine residue at the N-terminal part of the molecule. The molecular formula of tesamorelin acetate is C221H366N72O67S x C2H4O2 (x ≈ 7) and its molecular weight (free base) is 5135.9 Daltons. The structural formula of tesamorelin acetate is:
EGRIFTA is a sterile, white to off-white, preservative-free lyophilized powder for subcutaneous injection. After reconstitution with the supplied diluent (Sterile Water for Injection, USP), a solution of EGRIFTA is clear and colorless. Each single-dose vial of EGRIFTA contains 2 mg of tesamorelin and the following inactive ingredients: 20 mg mannitol, USP, 10 mg sucrose, NF, 0.78 mg histidine, USP and 0.05 mg polysorbate 20, NF.
In vitro, tesamorelin binds and stimulates human GRF receptors with similar potency as the endogenous GRF [see Clinical Pharmacology (12.2)].
Growth Hormone-Releasing Factor (GHRF), also known as Growth Hormone-Releasing Hormone (GHRH), is a hypothalamic peptide that acts on the pituitary somatotroph cells to stimulate the synthesis and pulsatile release of endogenous growth hormone (GH), which is both anabolic and lipolytic. GH exerts its effects by interacting with specific receptors on a variety of target cells, including chondrocytes, osteoblasts, myocytes, hepatocytes, and adipocytes, resulting in a host of pharmacodynamic effects. Some, but not all these effects, are primarily mediated by IGF-1 produced in the liver and in peripheral tissues.
Tesamorelin stimulates growth hormone secretion, and subsequently increases IGF-1 and IGFBP-3 levels. No clinically significant changes in the levels of other pituitary hormones, including thyroid-stimulating hormone (TSH), luteinizing hormone (LH), adrenocorticotropic hormone (ACTH) and prolactin, were observed in patients receiving EGRIFTA in clinical trials.
Absorption
The absolute bioavailability of EGRIFTA after subcutaneous administration of a 2 mg dose of EGRIFTA (1 mg/vial formulation) was determined to be less than 4% in healthy adult subjects.
Single and multiple dose pharmacokinetics of EGRIFTA have been characterized in healthy subjects and HIV-infected patients without lipodystrophy using a 2 mg dose of EGRIFTA (1 mg/vial formulation). Tesamorelin mean extent of absorption (AUC) was 34% higher in HIV-infected patients than healthy subjects. Tesamorelin peak plasma concentration (Cmax) was similar in HIV-infected patients and healthy subjects. The median peak plasma tesamorelin concentration (Tmax) was 0.15 h in both populations.
Following single dose of subcutaneous administration of 1.4 mg of EGRIFTA (2 mg/vial formulation) in healthy subjects, the mean [coefficient of variation (CV)] AUC0-inf was 889.1 (57%) pg.h/mL. The mean (CV) Cmax value was 2956.1 (47%) pg/mL and the median Tmax was 0.15 h.
The systemic exposure (Cmax and AUCs) of tesamorelin is similar between the 1.4 mg dose of EGRIFTA (2 mg/vial formulation) and the 2 mg dose of EGRIFTA (1 mg/vial formulation).
Distribution
The mean volume of distribution (±SD) of tesamorelin following a single subcutaneous administration of the 1.4 mg dose of EGRIFTA (2 mg/vial formulation) was 4.8 ± 1.9 L/kg in healthy subjects.
Elimination
Mean elimination half-life (t1/2) of tesamorelin was 8 minutes in healthy subjects after single dose subcutaneous administration of the 1.4 mg of EGRIFTA (2 mg/vial formulation).
Specific Populations
Pharmacokinetics of tesamorelin in patients with renal or hepatic impairment, in pediatric patients, or in elderly patients has not been established.
Drug Interactions
Simvastatin
The effect of multiple dose administration of EGRIFTA on the pharmacokinetics of simvastatin and simvastatin acid was evaluated in healthy subjects. Co-administration with simvastatin (a CYP3A substrate) resulted in 8% decrease in extent of absorption (AUCinf) and 5% increase in rate of absorption (Cmax) of simvastatin. For simvastatin acid there was a 15% decrease in AUCinf and 1% decrease in Cmax [see Drug Interactions (7.1)].
Ritonavir
The effect of multiple dose administration of EGRIFTA on the pharmacokinetics of ritonavir was evaluated in healthy subjects. Co-administration with ritonavir resulted in 9% decrease in AUCinf and 11% decrease in Cmax of ritonavir [see Drug Interactions (7.1)].
Life-time carcinogenicity studies in rodents have not been conducted with tesamorelin acetate. No potential mutagenicity of tesamorelin acetate was revealed in a battery of tests including induction of gene mutations in bacteria (the Ames test), gene mutations in mammalian cells grown in vitro (hamster CHOK1 cells), and chromosomal damage in intact animals (bone marrow cells in mice). There was no effect on fertility in male or female rats following administration of tesamorelin acetate at doses up to 0.6 mg/kg (approximately equal to clinical exposure) for 28 days in males or 14 days in females.
The safety and effectiveness of the EGRIFTA 2 mg/vial formulation has been established based on adequate and well controlled studies with the EGRIFTA 1 mg/vial formulation, as well as a demonstration of comparable bioavailability between the 1.4 mg EGRIFTA dose (2 mg/vial formulation) and the 2 mg EGRIFTA dose (1 mg/vial formulation) [see Clinical Pharmacology (12.3)].
Two multicenter, randomized, double-blind, placebo-controlled studies were conducted in HIV-infected patients with lipodystrophy and excess abdominal fat (abdominal lipohypertrophy). Study 1 and 2 consisted of a 26-week Main Phase and a 26-week Extension Phase, respectively. Main inclusion criteria were age 18 to 65 years, a waist circumference ≥95 cm (37.4 inches) and a waist-to-hip ratio ≥0.94 for men and ≥94 cm (37.0 inches) and ≥0.88 for women, respectively, and fasting blood glucose (FBG) <150 mg/dL (8.33 mmol/L). Main exclusion criteria included BMI ≤ 20 kg/m2, type 1 diabetes mellitus, type 2 diabetes mellitus, previous treatment with insulin or with oral hypoglycemic or insulin-sensitizing agents, history of malignancy, and hypopituitarism. Patients were on a stable anti-retroviral regimen for at least 8 weeks prior to randomization. Patients meeting the inclusion/exclusion criteria were randomized in a 2:1 ratio to receive 2 mg dose of EGRIFTA (1 mg/vial formulation) or placebo subcutaneously daily for 26 weeks. The primary efficacy assessment for each of these studies was the percent change from baseline to Week 26 in visceral adipose tissue (VAT), as assessed by computed tomography (CT) scan at L4-L5 vertebral level. Secondary endpoints included changes from baseline in patient-reported outcomes related to body image, triglycerides, ratio of total cholesterol to HDL cholesterol, IGF-1 levels, and safety parameters. Other endpoints included changes from baseline in waist circumference, abdominal subcutaneous tissue (SAT), trunk fat, and lean body mass. In both studies, EGRIFTA-treated patients completing the 26-week treatment period were re-randomized to blinded therapy with either daily placebo or 2 mg dose of EGRIFTA (1 mg/vial formulation) for an additional 26-week treatment period (Extension Phase) in order to assess maintenance of VAT reduction and to gather long-term safety data. For inclusion in the Extension Phase studies, subjects must have completed the Main Phase with FBG ≤ 150 mg/dL.
Main Phase (Baseline to Week 26):
Study 1 (NCT 00123253)
This study randomized 412 HIV-infected patients with lipodystrophy and excess abdominal fat to receive either a 2 mg dose of EGRIFTA (1 mg/vial formulation) (N=273) or placebo (N=137). At baseline for the two groups combined, mean age was 48 years; 86% were male; 75% were white, 14% were Black/African American, and 8% were Hispanic; mean weight was 90 kg; mean BMI was 29 kg/m2; mean waist circumference was 104 cm; mean hip circumference was 100 cm; mean VAT was 176 cm2; mean CD4 cell count was 606 cells/mm3; 69% had undetectable viral load (<50 copies/mL); and 33.7% randomized to EGRIFTA and 36.6% randomized to placebo had impaired glucose tolerance, while 5.6% randomized to EGRIFTA and 6.7% randomized to placebo had diet-controlled diabetes mellitus. The twenty-six week completion rate in Study 1 was 80%.
Study 2 (NCT 00435136)
This study randomized 404 HIV-infected patients with lipodystrophy and excess abdominal fat to receive either a 2 mg dose of EGRIFTA(1 mg/vial formulation) (N=270) or placebo (N=126). At baseline for the two groups combined, mean age was 48 years; 84% were male; 77% were white, 12% were Black/African American, and 9% were Hispanic; mean weight was 88 kg; mean BMI was 29 kg/m2; mean waist circumference was 105 cm; mean hip circumference was 100 cm; mean VAT was 189 cm2; mean CD4 cell count was 592 cells/mm3; 83% had undetectable viral load (<50 copies/mL); and 44% randomized to EGRIFTA and 40% randomized to placebo had impaired glucose tolerance, while 9% randomized to EGRIFTA and 10% randomized to placebo had diet-controlled type 2 diabetes mellitus. The twenty-six week completion rate in Study 2 was 74%.

At Week 26, treatment with a 2 mg dose of EGRIFTA(1 mg/vial formulation) resulted in a reduction from baseline in mean trunk fat of 1.0 kg in Study 1 and 0.8 kg in Study 2, respectively (compared with an increase of 0.4 kg in Study 1 and of 0.2 kg in Study 2, respectively, in patients receiving placebo). Treatment with EGRIFTA resulted in an increase from baseline in mean lean body mass of 1.3 kg in Study 1 and of 1.2 kg in Study 2, respectively (compared with a decrease of 0.2 kg in Study 1 and of 0.03 kg in Study 2, respectively, in patients receiving placebo).
Patient Reported Outcomes
Patients rated the degree of distress associated with their belly appearance on a 9-point rating scale that was then transformed to a score from 0 (extremely upsetting and distressing) to 100 (extremely encouraging). A score of 50 indicated neutral (no feeling either way). A positive change from baseline score indicated improvement, i.e., less distress.
The cumulative distribution of response (change from baseline to 26 weeks) is shown in Figure 1 for both treatment groups. A curve shifted to the right on this scale indicates a greater percentage of patients reporting improvement.

Extension Phase (Weeks 26-52):
In the double-blind Extension Phase, patients on a 2 mg dose of EGRIFTA (1 mg per vial formulation) completing the 26-week Main Phase were re-randomized to receive a 2 mg dose of EGRIFTA (1 mg per vial formulation) or placebo.
Study 1 (NCT 00123253)
This study re-randomized 207 HIV-infected patients with lipodystrophy who completed a 2 mg dose of EGRIFTA (1 mg/vial formulation) treatment in the Main Phase to receive either EGRIFTA (N=154) or placebo (N=50) for an additional 26-week duration (3:1 randomization ratio). At baseline (Week 26) for the two groups combined, mean age was 48 years; 88% were male; 78% were white, 12% were Black/African American, and 8% were Hispanic; mean weight was 90 kg; mean BMI was 29 kg/m2; mean waist circumference was 102 cm; mean hip circumference was 100 cm; mean VAT was 145 cm2; mean CD4 cell count was 639 cells/mm3; 68% had undetectable viral load (<50 copies/mL); and for those EGRIFTA-treated patients completing the 26-week treatment period that were re-randomized to EGRIFTA (T-T group) or re-randomized to placebo, 37% and 32%, respectively, had impaired glucose tolerance, while 2% re-randomized to EGRIFTA and 6% re-randomized to placebo had diet-controlled type 2 diabetes mellitus. The completion rate for patients randomized into the extension phase of Study 1 was 83%.
Study 2 (NCT 00435136)
This study re-randomized 177 HIV-infected patients with lipodystrophy who completed EGRIFTA treatment in the Main Phase to receive either a 2 mg dose of EGRIFTA(1 mg/vial formulation) (N=92) or placebo (N=85) for an additional 26-week duration (1:1 randomization ratio). At baseline (Week 26) for the two groups combined, mean age was 48 years; 90% were male; 84% were white, 9% were Black/African American, and 7% were Hispanic; mean weight was 89 kg; mean BMI was 28 kg/m2; mean waist circumference was 105 cm; mean hip circumference was 100 cm; mean VAT was 172 cm2; mean CD4 cell count was 579 cells/mm3; 82% had undetectable viral load (<50 copies/mL); and for those EGRIFTA-treated patients completing the 26-week treatment period that were re-randomized to EGRIFTA (T-T group) or re-randomized to placebo, 49% and 51%, respectively, had impaired glucose tolerance, while 4% re-randomized to EGRIFTA and 13% re-randomized to placebo had diet-controlled diabetes mellitus.

Increased Risk of Malignancy
Inform patients about the increased background risk of malignancies in HIV-positive patients and for patients with a history of neoplasms, inform them about the risk of malignancy reoccurrence [see Warnings and Precautions (5.1)].
Elevated IGF-1 Levels
Inform patients that treatment with EGRIFTA increases IGF-1 levels and that they will need periodic monitoring of their IGF-1 levels [see Warnings and Precautions (5.2)].
Fluid Retention
Inform patients that treatment with EGRIFTA may cause fluid retention, resulting in adverse reactions including edema, arthralgia, and carpal tunnel syndrome [see Warnings and Precautions (5.3)].
Glucose Intolerance or Diabetes Mellitus
Inform patients that treatment with EGRIFTA may result in glucose intolerance or diabetes mellitus. Advise patients that they will need to be monitored to see if impaired glucose tolerance or diabetes mellitus develops, and that if they have pre-existing diabetes mellitus, they may need adjustments to their anti-diabetic medications [see Warnings and Precautions (5.4)].
Hypersensitivity Reactions
Inform patients that hypersensitivity reactions (e.g., rash, urticaria) may occur during treatment with EGRIFTA. Advise patients to seek prompt medical attention and to immediately discontinue treatment with EGRIFTA if a reaction occurs [see Warnings and Precautions (5.5)].
Injection Site Reactions
Inform patients that injection site reactions may occur with EGRIFTA, including injection site erythema, pruritus, pain, irritation, and bruising. Advise patients to rotate the site of injection to reduce the risk of injection site reactions [see Warnings and Precautions (5.6)].
Pregnancy
Advise women to discontinue EGRIFTA if pregnancy occurs, as the drug offers no known benefit to pregnant women and could result in fetal harm [see Contraindications (4) and Use in Specific Populations (8.1)].
Lactation
Because of both the potential for HIV-1 infection transmission and serious adverse reactions in nursing infants, mothers receiving EGRIFTA should be instructed not to breastfeed [see Use in Specific Populations (8.2)].
Administration
Counsel patients that they should never share an EGRIFTA syringe with another person, even if the needle is changed. Sharing of syringes or needles between patients may pose a risk of transmission of infection.

Step 4: Take 1 EGRIFTA 2 mg vial (Figure A, e) from the Medication Box.
Step 5: Prepare to use your supplies:
How to mix EGRIFTA 2 mg vial
Step 1: Place the 1" 20-gauge needle used for mixing (Figure A, c), with its white protective cap in place, onto the syringe (Figure A, b). Hold the syringe firmly and twist the cap clockwise (to the right) until it closes securely. (See Figure B).
Figure B
Step 2: Remove the protective cap and insert the needle through the rubber stopper of the bottle of Sterile Water (Figure A, a; See Figure C for illustration). Turn the bottle and syringe upside down, pull back the plunger until the liquid reaches the 0.5 mL mark on the syringe, and throw away the bottle containing the unused Sterile Water. (See Figure D)
Figure C
Figure D
Step 3: Take the syringe with needle attached out of the Sterile Water bottle and insert the needle into the EGRIFTA vial. Push the plunger in slowly on a slight angle so water goes down the inside wall of the EGRIFTA vial instead of directly onto the powder to avoid foaming. (See Figure E)
Figure E
Step 4: Take the needle out of the vial and throw away the syringe and needle. (See Figure F and see section How should I dispose of the used syringes, needles, bottles and vials?)
Figure F
Step 5: Roll the vial gently in your hands for 30 seconds, until the Sterile Water and EGRIFTA powder are mixed well. Do not shake the vial. (See Figure G)
Figure G
Step 6: Place a new unused 1" 20-gauge needle used for mixing (Figure A, c), with its white protective cap in place, onto a a new unused syringe (Figure A, b). Hold the syringe firmly and twist the cap clockwise (to the right) until it closes securely. (See Figure H)
Figure H
Step 7: Remove the protective cap and insert the needle into the EGRIFTA vial (Figure A, a; see Figure I for illustration). Turn the bottle and syringe upside down, and pull down on the syringe until you see just the tip of the needle going through the rubber stopper, then pull back on the plunger until all the liquid inside the vial goes into the syringe. The level of medicine in the syringe should be around the 0.4 mL syringe mark. (See Figure J)
Figure I
Figure J
Step 8: Take the needle out of the vial. (See Figure K)
Figure K
Step 9: Place the needle cap on its side against a clean flat surface. Without touching the needle, hold the syringe and slide the needle carefully into the protective cap (See Figure L). Push the cap all the way or until it snaps shut (See Figure M). Do not touch the cap until it covers the needle completely.
Figure L
Figure M
Step 10: With the cap on the needle, remove the needle by holding the syringe firmly and twisting the cap counterclockwise (to the left). (See Figure N)
Figure N
Step 11: Place a ½" 30-gauge needle used for injection (Figure A, d), with its white protective cap in place, onto the syringe. Hold the syringe firmly and twist the cap clockwise (to the right) until it closes securely. (See Figure O)
