- RUCONEST is contraindicated in patients with a history of allergy to rabbits or rabbit-derived products.
- RUCONEST is contraindicated in patients with a history of life-threatening immediate hypersensitivity reactions to C1 esterase inhibitor preparations, including anaphylaxis.
Severe hypersensitivity reactions may occur
Patient Counseling Information (17)].
The signs and symptoms of hypersensitivity reactions may include hives, generalized urticaria, tightness of the chest, wheezing, hypotension, and/or anaphylaxis during or after injection of RUCONEST. Should symptoms occur, discontinue RUCONEST and institute appropriate treatment. Because hypersensitivity reactions may have symptoms similar to HAE attacks, treatment methods should be carefully considered.
5.2 Thromboembolic Events
Serious arterial and venous thromboembolic (TE) events have been reported at the recommended dose of plasma derived C1 esterase inhibitor products in patients with risk factors. Risk factors may include the presence of an indwelling venous catheter/access device, prior history of thrombosis, underlying atherosclerosis, use of oral contraceptives or certain androgens, morbid obesity, and immobility. Monitor patients with known risk factors for TE events during and after RUCONEST administration.
6 Adverse Reactions
The serious adverse reaction in clinical studies of RUCONEST was anaphylaxis.The most common adverse reactions (≥ 2%) reported in all clinical trials were headache, nausea, and diarrhea.
6.1 Clinical Trials Experience
Because clinical trials are conducted under widely varying conditions, the 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 clinical practice.The RUCONEST clinical development program evaluated a combined total of 940 administrations in 236 subjects (symptomatic and non-symptomatic). In clinical studies, a total of 205 symptomatic HAE patients received treatment with RUCONEST for a combined total of 650 acute angioedema attacks. Among these HAE patients, 83 were treated for a single HAE attack and 122 were treated for multiple attacks.Three randomized, placebo-controlled clinical trials (RCTs) were conducted in which 137 patients experiencing acute HAE attacks received RUCONEST (either an initial 50 U/kg or 100 U/kg body weight dose) or placebo (saline solution).Table 2 shows all adverse reactions (ARs) in the RCTs, compared with the placebo group.

N=205n(%)Headache19 (9%)Nausea5 (2%)Diarrhea5 (2%)Immunogenicity As with all therapeutic proteins, there is potential for immunogenicity. Pre- and post-exposure samples from 205 HAE patients treated for 650 acute attacks with RUCONEST were tested for the antibodies against plasma-derived C1INH or rhC1INH and for antibodies against host-related impurities (HRI). Testing was performed prior to and after treatment of a first attack and subsequent repeated attacks at 7, 22 or 28, and 90 days after RUCONEST treatment.Prior to the first exposure to RUCONEST, the frequency of anti-C1INH antibodies varied from 1.2% to 1.6% of samples. After the first exposure, the frequency of anti-C1INH antibodies varied from 0.6% to 1.0% of samples tested. After repeated exposures, the frequency of anti-C1INH antibodies varied from 0.5 to 2.2% of samples tested. The frequency of anti-HRI antibodies was 1.0% in pre-exposure samples, and after the first exposure varied from 3.5% to 4.6%. After repeated exposure, the frequency of anti-HRI antibodies varied from 5.7% to 17% of samples. At least 10% of subjects formed a specific antibody response to RUCONEST after five treated HAE attacks. No anti-C1INH neutralizing antibodies were detected. Observed anti-C1INH and anti-HRI antibodies were not associated with adverse clinical findings. 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 RUCONEST with the incidence of antibodies to other products may be misleading.Postmarketing ExperienceBecause postmarketing reporting of adverse reactions is voluntary and from a population of uncertain size, it is not always possible to reliably estimate the frequency of these reactions or establish a causal relationship to product exposure.Adverse reactions in HAE patients receiving RUCONEST include abdominal pain and rash.
Pregnancy Category B. Studies performed in rats and rabbits at doses up to 12.5 times the human dose of 50 U/kg could not exclude an effect on embryofetal development. There are, however, no adequate and well-controlled studies in pregnant women. Because animal reproduction studies are not always predictive of human response, RUCONEST should only be used during pregnancy if clearly needed.
8.2 Labor And Delivery
The safety and efficacy of RUCONEST administration prior to or during labor and delivery have not been established. Use only if clearly needed.
8.3 Nursing Mothers
It is not known if RUCONEST is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when RUCONEST is administered to a nursing woman.
8.4 Pediatric Use
The safety and efficacy of RUCONEST were evaluated in 17 adolescent patients (13-17 years of age) treated for 52 HAE attacks. Eight out of 17 (47%) adolescent patients experienced adverse reactions. No serious adverse reactions were reported in these patients. The most common reactions (occurring in at least 2 patients) were: abdominal pain, headache, and oropharyngeal pain.
8.5 Geriatric Use
The clinical studies of RUCONEST included seven patients older than 65 years. The clinical studies included an insufficient number of patients in this age group to determine if they respond differently from younger patients.
RUCONEST is a recombinant analogue of human complement component 1 esterase inhibitor for intravenous injection. RUCONEST is purified from the milk of transgenic rabbits, and supplied as a sterile, preservative-free, white/off-white lyophilized powder for reconstitution for injection. One U of rhC1INH activity is defined as the equivalent of C1 esterase inhibiting activity present in 1 mL of pooled normal plasma.RUCONEST is a soluble, single-chain glycoprotein containing 478 amino acids, with a molecular mass of 68 kDa, of which approximately 22% comprises oligosaccharide structures. The primary and secondary structures of the molecule and target protease selectivity are consistent with those of plasma-derived C1 esterase inhibitor.Each vial of RUCONEST contains 2100 U of rhC1INH, 937 mg of sucrose, 83.3 mg of sodium citrate dihydrate and 1.0 mg of citric acid monohydrate. After reconstitution with 14 mL of sterile Water for Injection, each vial of RUCONEST contains 150 U of rhC1INH per 1 mL in a 20 mM sodium citrate buffer with a pH of 6.8. RUCONEST does not contain preservatives and each vial is for single use only. RUCONEST is purified from the milk of transgenic rabbits. The rabbits are maintained in a closed colony that is controlled and routinely monitored for specific pathogens. The skimmed milk is screened for adventitious contaminants prior to further manufacture. The manufacturing process has been validated to demonstrate adequate capacity for removal and/or inactivation of viruses (
Table 4). RUCONEST contains less than 0.002% of host-related impurities.

12.1 Mechanism Of Action
C1 esterase inhibitor (C1INH) is a normal constituent of human blood and is one of the serine protease inhibitors (serpins). The primary function of C1INH is to regulate the activation of the complement and contact system pathways. Regulation of these systems is performed through the formation of complexes between the protease and the inhibitor, resulting in inactivation of both and consumption of the C1INH.C1INH exerts its inhibitory effect by irreversibly binding several proteases (target proteases) of the contact and complement systems. The effect of RUCONEST on the following target proteases was assessed
in vitro: activated C1s, kallikrein, factor XIIa and factor XIa. Inhibition kinetics were found to be comparable with those observed for plasma-derived human C1INH.
HAE patients have low levels of endogenous or functional C1INH. Although the events that induce attacks of angioedema in HAE patients are not well defined, it is thought that contact system activation, and resulting increased vascular permeability lead to the clinical manifestation of HAE attacks. Suppression of contact system activation by C1INH through the inactivation of plasma kallikrein and factor XIIa is thought to modulate vascular permeability by preventing the generation of bradykinin.
5Administration of RUCONEST increases plasma levels of functional C1INH activity.
The complement component (protein) C4 is a substrate for activated C1. Patients with HAE have low levels of C4 in the circulation; RUCONEST shows a dose-dependent restoration of complement homeostasis of C4 in HAE patients. A dose of 50 U/kg of RUCONEST increases plasma C1INH activity levels to greater than 0.7 U/mL (the lower limit of normal) in HAE patients.
The pharmacokinetics of RUCONEST was evaluated in a study of 12 asymptomatic HAE patients (dose ranged from 6.25 U/kg to 100 U/kg). Pharmacokinetics evaluation was performed by non-compartmental analysis, using functional C1INH levels. Following administration of RUCONEST (50 U/kg) in asymptomatic HAE patients (
Table 5), the mean Cmax was 1.2 U/mL, and the elimination half-life was approximately 2.5 hours. The clearance of RUCONEST was nonlinear (clearance decreased with increasing dose) over the dose range of 25-100 U/kg.

13.1 Carcinogenesis, Mutagenesis, Impairment Of Fertility
No animal studies have been conducted to evaluate the effects of RUCONEST on carcinogenesis and mutagenesis. Fertility was not evaluated in animal studies.
13.2 Animal Toxicology And/Or Pharmacology
Single- and repeat-dose studies of up to 14 days in rats, dogs, and cynomolgus monkeys with daily doses of RUCONEST up to 80 times the human dose (50 U/kg) were conducted. In a 14-day monkey toxicology study of intravenous doses up to 2000 U/kg twice daily, increases in AST and ALP were observed at doses of 500 U/kg and higher. No histopathological correlates were observed in the liver and the increases in liver enzymes were reversible. Histologic findings included changes in the size of thymic cortex and medulla, and microvacuoles in the epithelial cells lining the renal tubules. The renal tubular vacuolation was dose dependent, but was not accompanied by other histological changes in the kidney. This finding was only partially reversible at the highest dose level of 2000 U/kg twice daily. It was concluded that the NOAEL of RUCONEST was 1000 U/kg twice daily in this species. There were no adverse findings in a safety pharmacology study in dogs and a local tolerance study in rabbits. It is concluded that preclinical toxicology data for daily doses up to 40 times the proposed human dose of RUCONEST (50 U/kg) do not indicate a safety concern for the use of RUCONEST in humans.Embryo-fetal studies have been conducted in rabbits and rats at a dose of RUCONEST 12.5 times the human dose of 50 U/kg. In rats, no malformed fetuses were observed. In rabbits, an increase in the incidence of fetal cardiac vessel defects was observed (1.12% [2 cases] in the treatment group compared to 0.03% in historical controls). These defects are considered to be a chance finding, but a RUCONEST-related effect cannot be excluded.
14 Clinical Studies
The safety and efficacy of RUCONEST for treatment of acute angioedema attacks in patients with HAE was established in Study 1, a double-blind, randomized, placebo-controlled trial (RCT) which included an open-label extension (OLE) phase; and supported by the results of 2 additional RCTs and 2 additional OLE studies.Randomized, Controlled TrialsThe safety and efficacy of RUCONEST in the treatment of acute attacks in patients with hereditary angioedema were demonstrated in a placebo-controlled, double-blind, randomized study (Study 1). Supportive evidence of effectiveness is provided by two double-blind, randomized, placebo-controlled studies (Studies 2 and 3). Evidence for the efficacy of repeat treatment of HAE attacks is provided from the open-label extensions (OLE) of each of the three randomized studies.Study 1 was a randomized, double-blind, placebo-controlled trial that included an open-label extension (OLE) phase to assess the efficacy and safety of RUCONEST 50 U/kg in the treatment of acute attacks in patients with HAE. Seventy-five (75) adults and adolescent patients were randomized (3:2) to receive RUCONEST 50 U/kg (N = 44) or placebo (N = 31). Patients ranged in age from 17 to 69 years of age; 63% were female and 37% were male; 96% were Caucasian.The primary efficacy endpoint was the time to beginning of relief of symptoms, assessed using patient-reported responses to two questions from a Treatment Effect Questionnaire (TEQ). The TEQ required patients to assess the severity of their attack symptoms at each affected anatomic location, using a seven-point scale (“much worse” to “much better” [TEQ Question 1]), and whether their symptoms had begun to decrease notably since receiving the study medication (“yes” or “no” [TEQ Question 2]). To achieve the primary endpoint, a patient had to have a positive response to both questions along with persistence of improvement at the next assessment time (i.e., the same or better response). Rescue treatment with RUCONEST was available for patients who did not experience the beginning of relief at 4 hours after study drug administration, or earlier to patients who experienced life-threatening oropharyngeal-laryngeal angioedema symptoms. If a patient received a medication which could have impacted the efficacy evaluation or open-label RUCONEST as rescue medication, prior to achieving beginning of relief of symptoms, the time to beginning of relief of symptoms was censored at the last assessed time prior to medication use.In the RCT phase, the median time to beginning of relief of symptoms was statistically significantly shorter in patients treated with RUCONEST 50 U/kg compared with patients treated with placebo as assessed by the TEQ; (
Table 6, Figure 1).

Kaplan-Meier Plot of Time to Beginning of Relief of Symptoms (Study 1, RCT Phase)Among several planned subgroup analyses, descriptive statistics showed that in US patients a median time to beginning of relief of symptoms with persistence at the primary attack location (based on TEQ) was 98 minutes [95% CI:(45, 240); n=22] for those receiving RUCONEST and 90 minutes [95% CI: (50, -); n=16] for those receiving placebo. The hazard ratio for time to the beginning of relief of symptoms in this subpopulation was 1.20 [95% CI: 0.48 to 3.01] for patient receiving RUCONEST as compared with patient receiving placebo. Non-US patients receiving RUCONEST had a median time to beginning of relief of 90 minutes [95% CI: (63, 120); n=22] and non-US patients receiving placebo had a median time to beginning of relief of 334 minutes [95% CI: (150, -); n=15]. The hazard ratio for the non-US subgroup was 4.82 [95% CI: 1.58 to 14.72] for patients receiving RUCONEST compared to placebo.Examination of gender subgroups suggested a larger treatment effect in men than women. For women receiving RUCONEST, the median time to beginning of relief was 113 minutes [95% CI: (63, 151); n=28], and for women receiving placebo, the median time to beginning of relief was 105 minutes [95% CI: (60, 334); n=19]. The hazard ratio for women receiving RUCONEST versus placebo was 1.22 [95% CI: 0.60 to 2.48]. For men receiving RUCONEST, the median time to beginning of relief was 75 minutes [95% CI: (45, 210); n=16], and for men receiving placebo, the median time to beginning of relief was 480 minutes [95% CI: (150, -) n=12]. The hazard ratio for men receiving RUCONEST versus placebo was 3.94 [95% CI: 1.23 to 12.68].No plausible biological explanations for the regional or gender subgroup effects were found. One possible explanation is a larger-than-expected placebo response among US women. None of the subgroup confidence intervals were adjusted for multiplicity.Because almost all of the patients were Caucasian and were between 18 and 65 years of age, race and age subgroup analyses were not considered meaningful.Among patients who achieved relief within 4 hours, there were 4 (27%) patients in the placebo group who had a relapse of their symptoms within 24 hours as compared with 1 (3%) in the RUCONEST group. The proportion of patients who received RUCONEST as rescue medication was greater in patients randomized to placebo (13 of 31 patients; 42%) than in patients randomized to RUCONEST (5 of 44 patients; 11%).The efficacy of RUCONEST 50 U/kg for different anatomical locations of HAE attacks is summarized in

Forty-four patients who completed the RCT phase were enrolled into the OLE phase where they were treated for a total of 170 attacks. In this phase, the median time to beginning of relief of symptoms was 75 minutes (95% CI: 64, 90), consistent with the results of the RCT phase of the study (
Table 6). Results were also comparable across attacks, suggesting that the efficacy of RUCONEST 50 U/kg was maintained over repeated attacks of HAE. In the OLE phase of Study 1, 5/170 (3%) attacks received a second dose of RUCONEST 50 U/kg.
In Study 2 (North American RCT), patients were randomized to receive a single administration of either RUCONEST 50 U/kg (N=12), RUCONEST 100 U/kg (N=13) or placebo (N=13). Patients ranged in age from 17 to 66 years of age; 74% were female and 26% were male; and 92% were Caucasian.In Study 3 (European RCT), patients were randomized to receive a single administration of either RUCONEST 100 U/kg (N=16) or placebo (N=16). Patients ranged in age from 17 to 71 years of age: 53% were female and 47% were male; and 100% were Caucasian.Patients scored their symptoms using a visual analog scale (VAS) ranging from 0-100 mm. A VAS decrease of
> 20 mm compared with baseline with persistence of the improvement at two consecutive time points was considered the onset of relief in Studies 2 and 3.
In both Study 2 and 3, the efficacy of RUCONEST in the treatment of acute angioedema attacks was demonstrated by significantly shorter times to beginning of relief of symptoms based on the VAS (Figure 2).Figure 2. Mean VAS scores over time with 95% Confidence Intervals (Study 2 and 3, RCT Phase)In open-label extension studies of Study 2 and 3, 119 patients were treated with RUCONEST for a total of 362 acute angioedema attacks. As observed in Study 1, the efficacy of RUCONEST was maintained for repeat attacks.
