1 INDICATIONS AND USAGE VABRINTY is indicated for the treatment of advanced prostate cancer. VABRINTY is a gonadotropin releasing hormone (GnRH) agonist indicated for the treatment of advanced prostate cancer. ( 1 )

Dosage and administration

2 DOSAGE AND ADMINISTRATION VABRINTY is administered subcutaneously based on the following recommended dose and schedule: 7.5 mg subcutaneously every month ( 2.1 ) 22.5 mg subcutaneously every 3 months ( 2.1 ) 30 mg subcutaneously every 4 months ( 2.1 ) 45 mg subcutaneously every 6 months ( 2.1 ) See Full Prescribing Information for preparation and administration instructions. ( 2.2 , 2.3 ) 2.1 Recommended Dosage VABRINTY is administered subcutaneously and provides continuous release of leuprolide acetate over a one-, three-, four-, or six-month treatment period (Table 1). VABRINTY must be administered by a healthcare provider. The injection delivers the dose of leuprolide acetate incorporated in a polymer formulation. Table 1. VABRINTY Recommended Dosing Dosage 7.5 mg 22.5 mg 30 mg 45 mg Recommended dose 1 injection every month 1 injection every 3 months 1 injection every 4 months 1 injection every 6 months As with other drugs administered by subcutaneous injection, the injection site should vary periodically. The specific injection location should be an area with sufficient soft or loose subcutaneous tissue. In clinical trials, the injections were administered in the upper- or mid-abdominal area. Avoid areas with brawny or fibrous subcutaneous tissue or locations that could be rubbed or compressed (i.e., with a belt or clothing waistband). In patients treated with GnRH analogues for prostate cancer, treatment is usually continued upon development of metastatic castration-resistant prostate cancer. 2.2 Preparation Instructions Use aseptic technique throughout the procedure. As with other similar agents, the use of gloves is recommended during mixing and administration. Allow the product to reach room temperature before mixing. Once mixed, the product must be administered within 30 minutes or it should be discarded. VABRINTY is packaged in a carton containing: Tray containing pre-connected syringe system and desiccant pack Prescribing information Sterile safety needle and cap (located under the tray in carton) Follow the detailed instructions below to ensure correct preparation of VABRINTY prior to administration: Step 1 On a clean field open the tray by tearing off the foil from the corner and remove the contents. Discard the desiccant pack. Remove the pre-connected syringe system from the tray. Open the sterile safety needle package by peeling back the paper tab. Note: Syringe A and Syringe B should not be lined-up yet. The product should only be administered with the co-packaged, sterile safety needle. Step 2 Grasp the latching button on the coupling device with your finger and thumb and press until you hear a snapping sound. The two syringes will be aligned. Do not bend the pre-connected syringe system. Step 3 Holding the syringes in a horizontal position, transfer the liquid contents of Syringe A into the leuprolide acetate powder contained in Syringe B. Thoroughly mix the product for 60 cycles by pushing the contents back and forth between both syringes to obtain a uniform suspension. A cycle is one push of the Syringe A plunger and one push of the Syringe B plunger. When thoroughly mixed, the suspension will appear light tan to tan (VABRINTY 7.5 mg) or colorless to pale yellow (VABRINTY 22.5 mg, 30 mg, and 45 mg). Note: Product must be mixed as described; shaking will NOT provide adequate mixing. Do not bend. Step 4 After mixing, hold the syringes vertically (upright) with Syringe B (wide syringe) on the bottom. The syringes should remain securely coupled. Transfer all of the mixed product into Syringe B by depressing the Syringe A plunger and slightly withdrawing the Syringe B plunger. Step 5 While ensuring the Syringe A plunger is fully pushed down, hold the coupling device and unscrew Syringe B. This will disconnect Syringe B from the coupling device. Syringe A will remain attached to the coupling device. Note: Small air bubbles will remain in the formulation – this is acceptable. Do not purge the air bubbles from Syringe B as product may be lost! Step 6 Continue to hold Syringe B upright with the open end at the top. Hold back the white plunger on Syringe B to prevent loss of the product, and attach the safety needle and cap (the safety needle is located under the tray). Gently screw clockwise with approximately a three-quarter turn until the safety needle and cap are secure. Do not overtighten, as the needle hub may become damaged which could result in leakage of the product during injection. The safety shield may also be damaged if the safety needle and cap are screwed with too much force. Step 7 Move the safety shield away from the needle and towards the syringe. Pull off the cap immediately prior to administration. Note: Should the needle hub appear to be damaged, or leak, the product should NOT be used. The damaged safety needle and cap should NOT be replaced and the product should NOT be injected. In the event of damage to the needle hub, use a new replacement VABRINTY carton. mixing step2 step3 step4 step5 step6 step7 2.3 Administration Instructions 1. Select an injection site on the abdomen, upper buttocks, or another location with adequate amounts of subcutaneous tissue that does not have excessive pigment, nodules, lesions, or hair and hasn’t recently been used. 2. Cleanse the injection-site area with an alcohol swab (not enclosed). 3. Using the thumb and forefinger, grab and bunch the area of skin around the injection site. 4. Using your dominant hand, insert the needle quickly at a 90° angle to the skin surface. The depth of penetration will depend on the amount and fullness of the subcutaneous tissue and the length of the needle. After the needle is inserted, release the skin. 5. Inject the drug using a slow, steady push and press down on the plunger until the syringe is empty. Make sure all the drug has been injected before removing the needle. 6. Withdraw the needle quickly at the same 90° angle used for insertion. 7.

Contraindications

Hypersensitivity VABRINTY is contraindicated in patients with hypersensitivity to GnRH, GnRH agonist analogs or any of the components of VABRINTY. Anaphylactic reactions to synthetic GnRH or GnRH agonist analogs have been reported in the literature. Known hypersensitivity to GnRH, GnRH agonist analogs or any of the components of VABRINTY ( 4 )

Warnings and precautions

Tumor Flare: Transient increase in serum levels of testosterone during treatment may result in worsening of symptoms or onset of new signs and symptoms during the first few weeks of treatment, including bone pain, neuropathy, hematuria, bladder outlet obstruction, ureteral obstruction, or spinal cord compression. Monitor patients at risk closely and manage as appropriate. ( 5.1 , 5.7 ) Hyperglycemia and diabetes: Hyperglycemia and an increased risk of developing diabetes have been reported in men receiving GnRH analogs. Monitor blood glucose level and manage according to current clinical practice. ( 5.2 ) Cardiovascular diseases: Increased risk of myocardial infarction, sudden cardiac death and stroke has been reported in men. Monitor for cardiovascular disease and manage according to current clinical practice. ( 5.3 ) Effect on QT/QTc Interval: Androgen deprivation therapy may prolong the QT interval. Consider risks and benefits. ( 5.4 ) Convulsions have been observed in patients with or without a history of predisposing factors. Manage convulsions according to the current clinical practice. (5.5) Severe Cutaneous Adverse Reactions (SCARs), including Stevens-Johnson syndrome/toxic epidermal necrolysis, occurred in patients treated with VABRINTY. Interrupt VABRINTY if signs or symptoms of SCARs develop. Permanently discontinue if SCARs are confirmed. ( 5.6 ) Embryo-Fetal Toxicity: May cause fetal harm. ( 5.8 , 8.1 ) 5.1 Tumor Flare VABRINTY 7.5 mg, 22.5 mg, and 30 mg like other GnRH agonists, causes a transient increase in serum concentrations of testosterone during the first week of treatment. VABRINTY 45 mg causes a transient increase in serum concentrations of testosterone during the first two weeks of treatment. Patients may experience worsening of symptoms or onset of new signs and symptoms during the first few weeks of treatment, including bone pain, neuropathy, hematuria, or bladder outlet obstruction. Cases of ureteral obstruction and/or spinal cord compression, which may contribute to paralysis with or without fatal complications, have been observed in the treatment of advanced prostate cancer using GnRH agonists. Patients with metastatic vertebral lesions and/or with urinary tract obstruction should be closely observed during the first few weeks of therapy. If spinal cord compression or ureteral obstruction develops, standard treatment of these complications should be instituted. 5.2 Hyperglycemia and Diabetes Hyperglycemia and an increased risk of developing diabetes have been reported in men receiving GnRH agonists. Hyperglycemia may represent development of diabetes mellitus or worsening of glycemic control in patients with diabetes. Monitor blood glucose and/or glycosylated hemoglobin (HbA1c) periodically in patients receiving a GnRH agonist and manage with current practice for treatment of hyperglycemia or diabetes. 5.3 Cardiovascular Diseases Increased risk of developing myocardial infarction, sudden cardiac death and stroke has been reported in association with use of GnRH agonists in men. The risk appears low based on the reported odds ratios, and should be evaluated carefully along with cardiovascular risk factors when determining a treatment for patients with prostate cancer. Patients receiving a GnRH agonist should be monitored for symptoms and signs suggestive of development of cardiovascular disease and be managed according to current clinical practice. 5.4 Effect on QT/QTc Interval Androgen deprivation therapy may prolong the QT/QTc interval. Providers should consider whether the benefits of androgen deprivation therapy outweigh the potential risks in patients with congenital long QT syndrome, congestive heart failure, frequent electrolyte abnormalities, and in patients taking drugs known to prolong the QT interval. Electrolyte abnormalities should be corrected. Consider periodic monitoring of electrocardiograms and electrolytes. 5.5 Convulsions Postmarketing reports of convulsions have been observed in patients on leuprolide acetate therapy. These included patients with a history of seizures, epilepsy, cerebrovascular disorders, central nervous system anomalies or tumors, and in patients on concomitant medications that have been associated with convulsions such as bupropion and SSRIs. Convulsions have also been reported in patients in the absence of any of the conditions mentioned above. Patients receiving a GnRH agonist who experience convulsion should be managed according to current clinical practice. 5.6 Severe Cutaneous Adverse Reactions Severe cutaneous adverse reactions (SCARs), including Stevens-Johnson syndrome/toxic epidermal necrolysis (SJS/TEN), and erythema multiforme, occurred in patients receiving VABRINTY [see Adverse Reactions ( 6.2 )] . Monitor patients for the development of SCARs. Advise patients of the signs and symptoms of SCARs (e.g., a prodrome of fever, flu-like symptoms, mucosal lesions, progressive skin rash, or lymphadenopathy). If a SCAR is suspected, interrupt VABRINTY until the etiology of the reaction has been determined. Consultation with a dermatologist is recommended. If a SCAR is confirmed, or for other grade 4 skin reactions, permanently discontinue VABRINTY. 5.7 Laboratory Tests Monitor VABRINTY response by periodic measurement of serum concentrations of testosterone and prostate specific antigen. In the majority of patients, testosterone levels increased above Baseline during the first week, declining thereafter to Baseline levels or below by the end of the second or third week. Castrate levels were generally reached within two to four weeks. Castrate testosterone levels were maintained for the duration of the treatment with VABRINTY 7.5 mg. No increases to above the castrate level occurred in any of the patients. Castrate levels were generally maintained for the duration of treatment with VABRINTY 22.5 mg. Once castrate levels were achieved with VABRINTY 30 mg, most (86/89) patients remained suppressed throughout the study.

Side effects

The following clinically significant adverse reactions are described elsewhere in the labeling: Tumor Flare [see Warnings and Precautions ( 5.1 )] Hyperglycemia and Diabetes [see Warnings and Precautions ( 5.2 )] Cardiovascular Disease [see Warnings and Precautions ( 5.3 )] Effect on QT/QTc Interval [see Warnings and Precautions ( 5.4 )] Convulsions [see Warnings and Precautions ( 5.5 )] Severe Cutaneous Adverse Reactions [see Warnings and Precautions ( 5. 6 )] Most common adverse reactions in clinical studies (incidence ≥ 5%): Malaise, fatigue, hot flashes/sweats, and testicular atrophy. ( 6.1 ) As with other GnRH agonists, other adverse reactions, including decreased bone density and rare cases of pituitary apoplexy have been reported. ( 6.1 , 6.2 ) To report SUSPECTED ADVERSE REACTIONS, contact Uronova Pharmaceuticals, Inc. at 877-712-4575 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trial 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 to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The safety of all VABRINTY formulations was evaluated in clinical trials involving patients with advanced prostate cancer. In addition, the safety of VABRINTY 7.5 mg was evaluated in 8 surgically castrated males (Table 4). VABRINTY, like other GnRH analogs, caused a transient increase in serum testosterone concentrations during the first one to two weeks of treatment. Therefore, potential exacerbations of signs and symptoms of the disease during the first weeks of treatment are of concern in patients with vertebral metastases and/or urinary obstruction or hematuria. If these conditions are aggravated, it may lead to neurological problems such as weakness and/or paresthesia of the lower limbs or worsening of urinary symptoms [see Warnings and Precautions ( 5.7 )] . During the clinical trials, injection sites were closely monitored. Refer to Table 3 for a summary of reported injection site adverse reactions. Table 3.

One report characterized the erythema as mild and it resolved within 7 days. The other report characterized the erythema as moderate and it resolved within 15 days. Neither patient experienced erythema at multiple injection times. A single reaction reported as moderate pain resolved within two minutes and all 3 mild pain reactions resolved within several days following injection of VABRINTY 30 mg. Following injection of VABRINTY 30 mg, three of the 35 burning/stinging reactions were reported as moderate. Transient pain was reported as mild in intensity in nine of ten (90%) events and moderate in intensity in one of ten (10%) events following injection of VABRINTY 45 mg. Mild bruising was reported following 5 (2.3%) study injections and moderate bruising was reported following 2 (<1%) study injections of VABRINTY 45 mg. These localized adverse reactions were non-recurrent over time. No patient discontinued therapy due to an injection site adverse reaction. The following possibly or probably related systemic adverse reactions occurred during clinical trials with VABRINTY, and were reported in > 2% of patients (Table 4). Reactions considered not drug-related are excluded. Table 4.

Use in specific populations

Females and males of reproductive potential: VABRINTY may impair fertility. ( 8.3 ) Pediatric: Safety and effectiveness in pediatric patients have not been established. ( 8.4 ) Geriatric: This label reflects clinical trials for VABRINTY in prostate cancer where the majority of subjects were at least 65 years of age ( 8.5 ). 8.1 Pregnancy Risk Summary Based on findings in animal studies and mechanism of action, VABRINTY may cause fetal harm when administered to a pregnant woman [see Clinical Pharmacology ( 12.1 )] . There are no available data in pregnant women to inform the drug-associated risk. Expected hormonal changes that occur with VABRINTY treatment increase the risk for pregnancy loss. In animal developmental and reproductive studies, major fetal abnormalities were observed after administration of leuprolide acetate throughout gestation in rats. Advise pregnant patients and females of reproductive potential of the potential risk to the fetus (see Data) . Data Animal Data In animal developmental and reproductive studies, major fetal abnormalities were observed after administration of leuprolide acetate throughout gestation. There were increased fetal mortality and decreased fetal weights in rats and rabbits. The effects of fetal mortality are expected consequences of the alterations in hormonal levels brought about by this drug. 8.2 Lactation The safety and efficacy of VABRINTY have not been established in females. There is no information regarding the presence of VABRINTY in human milk, the effects on the breastfed child, or the effects on milk production. Because many drugs are excreted in human milk and because of the potential for serious adverse reactions in a breastfed child from VABRINTY, a decision should be made to discontinue breastfeeding or discontinue the drug, taking into account the importance of the drug to the mother. 8.3 Females and Males of Reproductive Potential Infertility Males Based on mechanism of action, VABRINTY may impair fertility in males of reproductive potential [see Clinical Pharmacology ( 12.1 )] . 8.4 Pediatric Use The safety and effectiveness of VABRINTY in pediatric patients have not been established. 8.5 Geriatric Use The majority of the patients (approximately 70%) studied in the clinical trials were age 70 and older. Clinical studies of VABRINTY did not include sufficient numbers of younger adult patients to determine if patients 65 years of age and older respond differently than younger adult patients.

Description

11 DESCRIPTION VABRINTY is a sterile polymeric matrix formulation of leuprolide acetate, a GnRH agonist, for subcutaneous injection. It is designed to deliver leuprolide acetate at a controlled rate over a one-, three-, four, or six-month therapeutic period. Leuprolide acetate is a synthetic nonapeptide analog of naturally occurring gonadotropin releasing hormone (GnRH) that, when given continuously, inhibits pituitary gonadotropin secretion and suppresses testicular and ovarian steroidogenesis. The analog possesses greater potency than the natural hormone. The chemical name is 5-oxo-L-prolyl-L-histidyl-L-tryptophyl-L-seryl-L-tyrosyl-D-leucyl-L-leucyl-L-arginyl-N-ethyl-L-prolinamide acetate (salt) with the following structural formula: VABRINTY is supplied as a pre-connected syringe system comprised of two prefilled syringes (syringe A and syringe B) connected using a coupling device. Immediately prior to administration, the contents of the pre-connected syringe system are mixed until homogenous. VABRINTY is administered subcutaneously, where it forms a solid drug delivery depot. Syringe A contains the in situ polymeric extended release technology consisting of a biodegradable poly (DL-lactide-co-glycolide) (PLGH or PLG) polymer formulation dissolved in a biocompatible solvent, N -methyl-2-pyrrolidone (NMP) and syringe B contains leuprolide acetate. Refer to Table 5 for the delivery system composition and reconstituted product formulation for each VABRINTY product. Table 5.

Mechanism of action

12.1 Mechanism of Action Leuprolide acetate, a gonadotropin releasing hormone (GnRH) agonist, acts as an inhibitor of gonadotropin secretion when given continuously in therapeutic doses. Animal and human studies indicate that after an initial stimulation, chronic administration of leuprolide acetate results in suppression of testicular and ovarian steroidogenesis. This effect is reversible upon discontinuation of drug therapy.
