Abstract
BACKGROUND Hereditary angioedema (HAE) is a rare and potentially life-threatening disease that manifests clinically as recurrent episodes of swelling affecting multiple anatomical locations. Long-term prophylaxis (LTP) aims to control the disease by preventing HAE attacks. Previously, treatments such as attenuated androgens have been used for LTP, but they have an unfavorable adverse effect profile. Today, these limitations may be overcome by patients transitioning to newer, targeted therapies including oral berotralstat and subcutaneous lanadelumab. This case series reports the transition process between different prophylactic therapies in a family with HAE in a real-world setting. RESULTS Four adult patient cases from the same family who underwent transitions in HAE prophylaxis are presented. Three were female and one male. Two patients who transitioned to berotralstat were initially prescribed attenuated androgens. Two patients were not taking LTP at the time of initiating targeted treatment but had previously been prescribed tranexamic acid. The length of transition varied between the patients, with the longest time taken to stabilize on new therapy being 26 months. All patients received regular follow-up in person or by telephone and all four required an adjustment from their initial treatment plan. CONCLUSIONS Transitioning between LTP in HAE may help improve control of attacks, avoid unwanted adverse effects, or better cater to individual patient preferences. Newer targeted therapies have been shown to be effective and should be discussed with patients. Shared decision-making is a tool that can aid these discussions. The transition journey between LTP therapies in HAE may not be straightforward and is specific to each patient. Physicians should consider complicating factors such as patient anxieties around changing treatment, adverse effects, preferred routes of administration, and speed of transition. Following patients closely during the transition period helps identify any issues, including difficulties with treatment adherence, and may allow the transition plan to be adapted when necessary.

Abstract
INTRODUCTION Hereditary angioedema (HAE) is a rare genetic disorder characterized by recurrent edema and predominantly caused by the dysregulation of the kinin-kallikrein system. AREAS COVERED This manuscript presents the results of preclinical and early clinical trials of newer drugs targeting the dysregulated kinin-kallikrein system. ATN-249 is an oral drug that has shown promising results in preclinical and Phase I studies, and good tolerability in the prophylactic treatment of attacks. KVD900 is also an oral agent developed for the on-demand treatment of HAE attacks. It has shown positive results in Phase I/II studies, with rapid absorption. The third drug, IONIS-PKKRx, is an antisense oligonucleotide targeting plasma prekallikrein mRNA. It has shown a dose-dependent reduction of plasma prekallikrein levels and proenzyme activation in Phase I/II studies, and has shown promising results. STAR-0215 is a long acting anti-activated kallikrein monoclonal antibody. A Phase 1a single ascending dose trial evaluated its safety, pharmacokinetics, and pharmacodynamics. Lastly, NTLA-2002 is an investigational gene-editing therapy. EXPERT OPINION The targeted treatment of the dysregulated kinin-kallikrein system with specific inhibitors is promising for the prevention of angioedema attacks. Ongoing phase III studies will provide further insight into the efficacy and long-term safety of these novel therapies, potentially expanding treatment options for HAE treatment.

Berotralstat for long-term prophylaxis of hereditary angioedema in Japan: Parts 2 and 3 of the randomized APeX-J Phase III trial. World Allergy Organ J 2024; 17:100882. [PMID: 38445295 PMCID: PMC10914521 DOI: 10.1016/j.waojou.2024.100882] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/27/2023] [Revised: 02/08/2024] [Accepted: 02/13/2024] [Indexed: 03/07/2024] Open
Abstract
Background Berotralstat is a once-daily oral inhibitor of plasma kallikrein for the prophylaxis of hereditary angioedema (HAE) in patients ≥12 years. APeX-J aimed to evaluate the efficacy and safety of berotralstat in Japan. Methods APeX-J was a Phase III trial comprising 3 parts (NCT03873116). Part 1 was a randomized, placebo-controlled evaluation of berotralstat 150 or 110 mg over 24 weeks. Part 2 was a 28-week dose-blinded phase in which berotralstat-treated patients continued the same dose and placebo patients were re-randomized to berotralstat 150 or 110 mg. In Part 3, all patients remaining on study received berotralstat 150 mg in an open-label manner for up to an additional 52 weeks. The primary endpoint of Parts 2 and 3 was long-term safety and tolerability, and secondary endpoints examined effectiveness. Results Seventeen patients entered Part 2, and 11 continued into Part 3. Treatment-emergent adverse events (TEAEs) were reported by 14/17 patients (82.4%) in Parts 2 or 3; the most common were nasopharyngitis, abdominal pain, cystitis, influenza, and vertigo. One patient (5.9%) experienced a drug-related TEAE (Grade 4 increased hepatic enzyme). No drug-related serious TEAEs were reported. For patients who completed 26 months of treatment with berotralstat 150 mg (n = 5), mean (standard error of the mean) monthly HAE attack rates and on-demand medication use decreased from baseline by 1.15 (0.09) attacks/month and 2.8 (0.64) doses/month, respectively. Sustained improvements were also observed in patient quality of life and treatment satisfaction. Conclusions Long-term prophylaxis with berotralstat raised no new safety signals and was effective at reducing attacks and improving patient-reported outcomes. Trial registration ClinicalTrials.gov NCT03873116. Registered March 13, 2019. Retrospectively registered.

Abstract
Background With no approved long-term prophylaxis (LTP) for the prevention of hereditary angioedema (HAE) attacks in Hong Kong, patients rely on compassionate use programs and drug trials. Moreover, studies regarding the use and efficacy of LTP in Asia are lacking. Objectives Our aim was to assess 2 LTP medications for HAE in Hong Kong: lanadelumab and garadacimab. Methods A prospective study was performed. Adult patients with a diagnosis of type I or type II HAE with 1 or more expert-confirmed attacks per month were consecutively recruited. The patients had been receiving treatment for at least 6 months. Clinical data were obtained, and questionnaires were administered before treatment periodically for at least 6 months following initiation of LTP. Results Almost one-third of the patients with HAE experienced frequent attacks and began receiving LTP (8 of the 11 received garadacimab and 3 of the 11 received lanadelumab). At baseline, the time-normalized number of HAE attacks was 2.5 plus or minus 1.3 per month. At month 6, there was an overall reduction of time-normalized number of attacks per month of -2.4 attacks per month (95% CI = -3.3 to -1.5. [P < .01]). The time-normalized number of HAE attacks at month 6 was 0.1 plus or minus 0.1 per month. More than 70% of the patients (8 of 11) were completely attack-free during the 6-month period while receiving LTP, and no patients required hospitalization. LTP improved patients' scores of the Angioedema Quality-of-Life Questionnaire (P < .001) and reduced activity impairment due to health (P = .008). Patients experienced significant improvement across all dimensions of the Treatment Satisfaction for Medication Questionnaire (54.5%-76.8% [P = .002]), and no adverse events were reported. Conclusion The patients receiving LTP with garadacimab and lanadelumab experienced a significant reduction in number of HAE attacks and improvement in quality of life, and they were satisfied with treatment.

Abstract
INTRODUCTION Hereditary angioedema (HAE) is characterized by recurrent subcutaneously and/or submucosally localized edematous swellings. The first symptoms often appear in childhood, and they may become more frequent and severe in puberty. Since the appearance of HAE attacks is unpredictable regarding the localization and the frequency, the attacks put a significant burden on the patients and crucially impacts their quality of life. AREAS COVERED This review article analyzes the safety data acquired from the clinical trials conducted with the currently available medicinal products for the prophylactic treatment of hereditary angioedema due to C1 inhibitor deficiency and the safety data of observatory studies based on clinical practice. A review of the published literature was conducted using the PubMed database, clinical trials from ClinicalTrials.gov, and abstracts published at scientific conferences. EXPERT OPINION The currently available therapeutic products have a good safety and efficiency profile and the international guidelines recommend them as first-line treatments. The choice should be made based on the evaluation of the availability and the preference of the patient.

Abstract
BACKGROUND Hereditary angioedema (HAE), which is caused by C1-inhibitor (C1-INH) deficiency or dysfunction, is a rare and potentially life-threatening disease. In patients with HAE, excess production of bradykinin causes acute unpredictable recurrent attacks of angioedema in localized regions, including the larynx and intestines. Given the fact that HAE is an autosomal dominant disease, C1-INH produced in patients with HAE is 50% of that produced in healthy individuals. However, most patients with HAE present plasma C1-INH function of < 25% owing to the chronic consumption of C1-INH by kallikrein-kinin, contact, complement, coagulation, and fibrinolysis cascades. Recently, several therapeutic options have been developed for acute attacks and prophylaxis in the treatment of HAE; however, currently, there is no curative therapy for HAE. CASE PRESENTATION Here we report the case of a 48-year-old male patient who presented with a long-standing history of HAE and underwent bone marrow transplantation (BMT) for acute myeloid leukemia (AML) at the age of 39 years and has been in complete remission of AML and HAE thereafter. Notably, after BMT, his C1-INH function gradually increased as follows: < 25%, 29%, 37%, and 45.6%. Since his 20 s, he intermittently presented with an acute attack of HAE once every 3 months from the initial attack. Further, after undergoing BMT, the number of acute attacks decreased to twice within 4 years until the age of 45 years, and subsequently, the patient has been free of acute attacks. C1-INH is mainly synthesized by hepatocytes, but it is known to be partially produced and secreted from peripheral blood monocytes, macrophages, endothelial cells, and fibroblasts. We speculate that the C1-INH function may be increased by extrahepatic production of C1-INH, possibly synthesized by differentiated cells derived from hematopoietic and mesenchymal stem cells after BMT. CONCLUSIONS This case report supports efforts to focus on extrahepatic production of C1-INH in the next strategy of new treatment development for HAE.

Abstract
The inclusion of fluorine atoms or heterocyclic moiety into drug structures represents a recurrent motif in medicinal chemistry. The combination of these two features is constantly appearing in new molecular entities with various biological activities. This is demonstrated by the increasing number of newly synthesized fluorinated heterocyclic compounds among the Food and Drug Administration FDA-approved drugs. In this review, the biological activity, as well as the synthetic aspects, of 33 recently FDA-approved fluorinated heterocyclic drugs from 2016 to 2022 are highlighted.

Abstract
Hereditary angioedema (HAE) is a condition characterized by episodes of cutaneous and submucosal edema. Angioedema of the extremities and abdominal attacks are the most common manifestations of the disease. It can also affect the upper airways with the potential of becoming life-threatening. The two most common causes of HAE are a deficiency of C1 inhibitor (classified as type 1 HAE) or a dysfunction of C1 inhibitor (type 2 HAE). A malfunction or deficiency of C1 inhibitor leads to an overactivated plasma kallikrein (an inflammatory vasoactive peptide), that increases bradykinin, mediating the angioedema episodes in patients with HAE. To minimize the difficulties of this pathology and to improve patients' quality of life, prevention of this condition is essential. Berotralstat is a unique option for oral administration for routine prophylaxis. This drug acts by binding to kallikrein and reducing its plasma activity, lowering bradykinin levels. Open-label studies have demonstrated the effectiveness of a single daily dose of berotralstat 150 mg in preventing HAE attacks. This review aims to examine studies performed to elucidate the efficacy, safety, and tolerability of berotralstat.

Abstract
Chirality is a major theme in the design, discovery, and development of new drugs. Historically, pharmaceuticals have been synthesized as racemic mixtures. However, the enantiomeric forms of drug molecules have distinct biological properties. One enantiomer may be responsible for the desired therapeutic effect (eutomer), whereas the other may be inactive, interfere with the therapeutic form, or exhibit toxicity (distomer). Classical chemical synthesis usually leads to a racemic mixture unless stereospecific synthesis is employed. To meet the requirements of single-enantiomeric drugs, asymmetric synthesis has evolved at the forefront of drug discovery. Asymmetric synthesis involves the conversion of an achiral starting material into a chiral product. This review emphasizes the methods used for synthesizing FDA-approved chiral drugs during 2016–2020, with a special focus on asymmetric synthesis by means of chiral induction, resolution, or chiral pool.

Abstract
INTRODUCTION Hereditary angioedema due to C1-inhibitor deficiency (C1-INH-HAE) imposes a significant disease burden on patients and their families. Unpredictable episodes of angioedema, which can lead to life-threatening conditions, have a significant impact on the quality of life of the patient. The fundamental aim of the treatment of C1-INH-HAE is to ensure that patients can lead a normal life. The most effective way to do this is to prevent the onset of angioedema attacks. AREAS COVERED This review gives a brief overview of the safety and efficacy of the oral kallikrein inhibitor berotralstat in C1-INH-HAE disease. It provides a comprehensive synopsis of the results of the first clinical trials with a targeted oral kallikrein inhibitor (APeX-1 [NCT02870972]; ZENITH-1 [NCT03240133]; APeX-2 [NCT03485911]; APeX-S [NCT03472040]; APeX-J [NCT03873116]), reviewing evidence on the efficacy and safety of the drug, and placing berotralstat on the spectrum of long-term prophylactic therapeutic options. EXPERT OPINION The availability of the first targeted oral prophylactic drug, the kallikrein inhibitor berotralstat, in 2021, is a milestone in the treatment of patients with hereditary angioedema.

Abstract
BACKGROUND Hereditary angioedema (HAE) is a serious and potentially life-threatening condition that causes acute attacks of swelling, pain and reduced quality of life. People with Type I HAE (approximately 80% of all HAE cases) have insufficient amounts of C1 esterase inhibitor (C1-INH) protein; people with Type II HAE (approximately 20% of all cases) may have normal C1-INH concentrations, but, due to genetic mutations, these do not function properly. A few people, predominantly females, experience HAE despite having normal C1-INH levels and C1-INH function (rare Type III HAE). Several new drugs have been developed to treat acute attacks and prevent recurrence of attacks. There is currently no systematic review and meta-analysis that included all preventive medications for HAE. OBJECTIVES To assess the benefits and harms of interventions for the long-term prevention of HAE attacks in people with Type I, Type II or Type III HAE. SEARCH METHODS We used standard, extensive Cochrane search methods. The latest search date was 3 August 2021. SELECTION CRITERIA We included randomised controlled trials in children or adults with HAE that used medications to prevent HAE attacks. The comparators could be placebo or active comparator, or both; approved and experimental drug trials were eligible for inclusion. There were no restrictions on dose, frequency or intensity of treatment. The minimum length of four weeks of treatment was required for inclusion; this criterion excluded the acute treatment of HAE attacks. DATA COLLECTION AND ANALYSIS We used standard Cochrane methods. Our primary outcomes were 1. HAE attacks (number of attacks per person, per population) and change in number of HAE attacks; 2. mortality and 3. serious adverse events (e.g. hepatic dysfunction, hepatic toxicity and deleterious changes in blood tests). Our secondary outcomes were 4. quality of life; 5. severity of breakthrough attacks; 6. disability and 7. adverse events (e.g. weight gain, mild psychological changes and body hair). We used GRADE to assess certainty of evidence for each outcome. MAIN RESULTS We identified 15 studies (912 participants) that met the inclusion criteria. The studies included people with Type I and II HAE. The studies investigated avoralstat, berotralstat, subcutaneous C1-INH, plasma-derived C1-INH, nanofiltered C1-INH, recombinant human C1-INH, danazol, and lanadelumab for the prevention of HAE attacks. We did not find any studies on the use of tranexamic acid for prevention of HAE attacks. All drugs except avoralstat reduced the number of HAE attacks compared with placebo. For breakthrough attacks that occurred despite prophylactic treatment, intravenous and subcutaneous forms of C1-INH and lanadelumab reduced attack severity. It is not known whether other drugs have a similar effect, as the severity of breakthrough attacks in people taking drugs other than C1-INH and lanadelumab was not reported. For quality of life, avoralstat, berotralstat, C1-INH (all forms) and lanadelumab increased quality of life compared with placebo; there were no data for danazol. Four studies reported on changes in disability during treatment with C1-INH, berotralstat and lanadelumab; all three drugs decreased disability compared with placebo. Adverse events, including serious adverse events, did not occur at a rate higher than placebo. However, serious adverse event data and other adverse event data were not available for danazol, which prevented us from drawing conclusions about the absolute or relative safety of this drug. No deaths were reported in the included studies. The analysis was limited by the small number of studies, the small number of participants in each study and the lack of data on older drugs, therefore the certainty of the evidence is low. Given the rarity of HAE, it is not surprising that drugs were rarely directly compared, which does not allow conclusions on the comparative efficacy of the various drugs for people with HAE. Finally, we did not identify any studies that included people with Type III HAE. Therefore, we cannot draw any conclusions about the efficacy or safety of any drug in people with this form of HAE. AUTHORS' CONCLUSIONS The available data suggest that berotralstat, C1-INH (subcutaneous, plasma-derived, nanofiltered and recombinant), danazol and lanadelumab are effective in lowering the risk or incidence (or both) of HAE attacks. In addition, C1-INH and lanadelumab decrease the severity of breakthrough attacks (data for other drugs were not available). Avoralstat, berotralstat, C1-INH (all forms) and lanadelumab increase quality of life and do not increase the risk of adverse events, including serious adverse events. It is possible that danazol, subcutaneous C1-INH and recombinant human C1-INH are more effective than berotralstat and lanadelumab in reducing the risk of breakthrough attacks, but the small number of studies and the small size of the studies means that the certainty of the evidence is low. This and the lack of head-to-head trials prevented us from drawing firm conclusions on the relative efficacy of the drugs.

Abstract
Hereditary Angioedema (HAE) is a rare and disabling disease for which early diagnosis and effective therapy are critical. This revision and update of the global WAO/EAACI guideline on the diagnosis and management of HAE provides up-to-date guidance for the management of HAE. For this update and revision of the guideline, an international panel of experts reviewed the existing evidence, developed 28 recommendations, and established consensus by an online DELPHI process. The goal of these recommendations and guideline is to help physicians and their patients in making rational decisions in the management of HAE with deficient C1-inhibitor (type 1) and HAE with dysfunctional C1-inhibitor (type 2), by providing guidance on common and important clinical issues, such as: 1) How should HAE be diagnosed? 2) When should HAE patients receive prophylactic on top of on-demand treatment and what treatments should be used? 3) What are the goals of treatment? 4) Should HAE management be different for special HAE patient groups such as children or pregnant/breast feeding women? 5) How should HAE patients monitor their disease activity, impact, and control? It is also the intention of this guideline to help establish global standards for the management of HAE and to encourage and facilitate the use of recommended diagnostics and therapies for all patients.

Abstract
Background: Patients' satisfaction is important for the success of the management of chronic diseases. Objective: Our aim was to evaluate the satisfaction level of the patients with hereditary angioedema (HAE) for icatibant treatment. Methods: Patients with HAE C1 esterase inhibitor (C1-INH) were evaluated by using a questionnaire that included details of their icatibant-treated attacks. Patients' demographic and clinical features were collected from their medical records and personal attack diaries. The visual analog scale was used for determining the attack severity. Results: Of the total 161 patients with HAE C1-INH, 91% had HAE type I and were included in the study. Patients reported a median (interquartile range [IQR]) attacks of 2 (0.5-3) per month and 16 (4.5-36) attacks per year. The median (IQR) frequency of attacks treated with icatibant was 6 (0-20) per year. The mean ± standard deviation (SD) duration of treatment with icatibant was 3 ± 2.3 years. The self-administration rate was 91.3%. The mean ± SD time to administration and time to onset of symptom resolution were 1.6 ± 1.1 hours and 1.7 ± 1.3 hours, respectively. There was a correlation between the time to administration and time to onset of symptom resolution (r = 0.566; p < 0.0001). A total of 125 patients (77%) reported that they were very satisfied or satisfied with icatibant. No correlation was observed between the satisfaction level and the attack sites; however, the patients with more severe attacks were more satisfied with icatibant (p < 0.0001). A total of 52 patients reported 74 mild local reactions. Systemic reactions were not observed. Conclusion: The current real-life study showed that icatibant was safe and effective. Moreover, the patients' satisfaction level with icatibant was high. We believe that the availability of icatibant should be encouraged during HAE attacks because it enables patients to be more involved in their disease management.

Abstract
Hereditary angioedema (HAE) is an autosomal dominant disorder characterized by recurrent episodes of swelling of the skin, larynx, gastrointestinal tract, genitals, and extremities that can be disruptive to patient quality of life. Dysregulation of plasma kallikrein activity leads to increased production and accumulation of bradykinin in HAE and causes attacks of angioedema. Plasma kallikrein is a serine protease essential for the formation of bradykinin. Berotralstat is a potent, highly selective, orally bioavailable small‐molecule plasma kallikrein inhibitor that has been approved to prevent attacks of HAE in adults and children 12 years of age and older. Population pharmacokinetic (PK) analyses were conducted to describe the PK of berotralstat (BCX7353; Orladeyo™) and to evaluate the covariates that may explain variability in PK. The PK of berotralstat were characterized by population PK modeling of data from 13 clinical studies and a total of 771 healthy subjects and patients with HAE. The PK profile was well described by a three‐compartment model with first‐order absorption including an absorption lag time and linear elimination. Among the covariates tested, the effects of bilirubin and food were found not to be clinically significant and were removed from the model. Covariate analysis indicated significant effects of dose on bioavailability and weight on berotralstat clearance and volume. Despite the covariate effect of weight, simulations in adolescents and adults who were underweight, low weight, and overweight demonstrated similar predicted exposures to those observed at therapeutic doses in a clinical trial. Therefore, no dose adjustment is required in these HAE patient subpopulations.

Abstract
BACKGROUND Hereditary angioedema (HAE) affects all races and both sexes equally. Minority patients are underrepresented in clinical trials and may be at risk for additional disease burden. OBJECTIVES To examine racial and ethnic disparities in the research and care of patients with HAE. METHODS We conducted a retrospective population-based study using TriNetX Diamond Network. International Classification of Diseases, 10th Revision, Current Procedural Terminology, and RxNorm codes identified patients with HAE. The proportions of White, Black, and Hispanic patients with HAE were contrasted with racial and ethnic distributions of patients with HAE in clinical trials. Lifetime prevalence of mental health disorders and HAE treatments was contrasted among different racial and ethnic groups. RESULTS A population-based search identified 2122 patients with HAE. The prevalence of HAE among Black patients (1.64/100,000 patients) mirrored that of White patients (1.47/100,000 patients), whereas there was a lower HAE prevalence among Hispanic patients (0.80/100,000 patients). The demographics of the 1274 patients with HAE included in phase 2/3 clinical trials differed significantly from population-based data with overrepresentation of White patients (89.9% vs 77.9%) and underrepresentation of Black patients (3.8% vs 13.6%) and Hispanic patients (1.3% vs 8.1%). Across the different racial and ethnic groups of patients with HAE, the prevalence of mental health disorders was comparatively higher than among patients without HAE. Whereas depression was equally prevalent across the different HAE racial and ethnic groups, anxiety was more prevalent among White patients. CONCLUSIONS Clinical trials for Food and Drug Administration-approved HAE medications underrepresent minority patients. Hereditary angioedema remains underdiagnosed in Hispanic patients. Other than a lower prevalence of anxiety disorders among Black patients relative to White patients, the mental health impact of HAE is equally distributed across the different racial and ethnic groups.

Abstract
Hereditary angioedema (HAE) is a rare disease that causes serious health problem and affects on quality of life for patient due to recurrent episodes of angioedema in various body such as the skin, larynx, digestive tract, and limbs. Many HAE patients have deficiency or dysfunction of C1 inhibitor, impaired regulation of plasma kallikrein activity and overproduction of bradykinin, resulting in leading to episodes of increased capillary hyper permeability and angioedema. Therapy of HAE consists of on-demand treatment for acute attack and prophylactic treatment by suppressing the onset of acute attack in the short and long term. However, no drug has been approved for long-term prophylaxis in Japan. Berotralstat hydrochloride (ORLADEYO Capsules 150 mg) is an oral, selective plasma kallikrein inhibitor approved for the suppression of the onset of acute attacks in HAE in Japan in January 2021. Preclinical studies demonstrated that Berotralstat is a potent and highly specific inhibitor of human plasma kallikrein activity. Berotralstat suppressed bradykinin production in the HUVEC system. Clinical studies demonstrated that oral administration of Berotralstat to HAE type I or type II patients at a dose of 150 mg once daily showed a reduction of HAE attack rate and clinically significant change in angioedema quality of life score. The most common side effect was gastrointestinal symptoms. In conclusion, preclinical and clinical data indicated that Berotralstat is an effective treatment for long-term prophylactic treatment by suppressing the onset of acute attack in HAE patient and is considered to be a useful treatment option for patients.

Abstract
OBJECTIVE The purpose of this article is to review the available trials that led to the Food and Drug Administration (FDA) approval of berotralstat, an oral kallikrein inhibitor, for the prevention of hereditary angioedema (HAE) attacks. DATA SOURCES PubMed and ClincalTrials.gov were searched using key term berotralstat to identify phase III clinical trials related to the FDA approval of berotralstat from April 2018 to May 2021. STUDY SELECTION AND DATA EXTRACTION Trials selected were those that influenced the FDA approval of berotralstat or provided novel information regarding the safety and efficacy of this therapy in the treatment of HAE. DATA SYNTHESIS Both APeX-2 and ApeX-J found clinically significant benefit with berotralstat 150 mg daily for reduction in HAE attacks when compared with placebo (1.31 vs 2.35, P < 0.001, and 1.11 vs 2.18, P < 0.001, attacks in the APeX-2 and APeX-J trials, respectively). APeX-2 also showed a statistically significant benefit for berotralstat 110 mg daily (1.65 vs 2.35 attacks [1.65 attacks, P = 0.024]). RELEVANCE TO PATIENT CARE AND CLINICAL PRACTICE An advantage berotralstat has over the other approved therapies is that it is administered orally, which may garner patient preference because of ease of administration. Berotralstat has also shown a potential benefit in reducing the need for standard-of-care treatment for HAE attacks, which has not been studied with alternative agents. CONCLUSIONS Berotralstat 150 mg daily has been proven safe and effective in clinical studies and appears to be a viable oral alternative to parenteral medications currently used in HAE prophylaxis.

Abstract
BACKGROUND Berotralstat (BCX7353) is an oral, once-daily inhibitor of plasma kallikrein recently approved for prevention of angioedema attacks in adults and adolescents with hereditary angioedema (HAE). The objective of this report is to summarize results from an interim analysis of an ongoing long-term safety study of berotralstat in patients with HAE. METHODS APeX-S is an ongoing, phase 2, open-label study conducted in 22 countries (ClinicalTrials.gov, NCT03472040). Eligible patients with a clinical diagnosis of HAE due to C1 inhibitor deficiency (HAE-C1-INH) were centrally allocated to receive berotralstat 150 or 110 mg once daily. The primary objective was to determine long-term safety and the secondary objective was to evaluate effectiveness. RESULTS Enrolled patients (N = 227) received berotralstat 150 mg (n = 127) or 110 mg (n = 100) once daily. The median (range) duration of exposure was 342 (11-540) and 307 (14-429) days for the 150-mg and 110-mg groups, respectively. Treatment-emergent adverse events (TEAEs) occurred in 91% (n = 206) of patients. The most common TEAEs across treatment groups were upper respiratory tract infection (n = 91, 40%), abdominal pain (n = 57, 25%), headache (n = 40, 18%), and diarrhea (n = 31, 14%) and were mostly mild to moderate. Fifty percent (n = 113) of patients had at least one drug-related adverse event (AE; 150 mg, n = 57 [45%]; 110 mg, n = 56 [56%]), and discontinuations due to AEs occurred in 19 (8%) patients (150 mg, n = 13 [10%]; 110 mg, n = 6 [6%]). Three (1.3%) patients experienced a drug-related serious TEAE. Among patients who received berotralstat through 48 weeks (150 mg, n = 73; 110 mg, n = 30), median HAE attack rates were low in month 1 (150 mg, 1.0 attacks/month; 110 mg, 0.5 attacks/month) and remained low through 12 months (0 attacks/month in both dose groups). Mean HAE attack rates followed a similar trend, and no evidence for patient tolerance to berotralstat emerged. In both dose groups, angioedema quality of life scores showed clinically meaningful changes from baseline. CONCLUSIONS In this analysis, both berotralstat doses, 150 and 110 mg once daily, were generally well tolerated. Effectiveness results support the durability and robustness of berotralstat as prophylactic therapy in patients with HAE. TRIAL REGISTRATION The study is registered with ClinicalTrials.gov (NCT03472040).

Abstract
While the COVID-19 pandemic also affected the work of regulatory authorities, the US Food and Drug Administration approved a total of 53 new drugs in 2020, one of the highest numbers in the past decades. Most newly approved drugs related to oncology (34%) and neurology (15%). We discuss these new drugs by level of innovation they provide, i.e., first to treat a condition, first using a novel mechanisms of action, and "others." Six drugs were first in indication, 15 first using a novel mechanism of action, and 32 other. This includes many drugs for the treatment of orphan indications and some for the treatment of tropical diseases previously neglected for commercial reasons. Small molecules continue to dominate new drug approvals, followed by antibodies. Of note, newly approved drugs also included small-interfering RNAs and antisense oligonucleotides. These data show that the trend for declines in drug discovery and development has clearly been broken.

Abstract
Berotralstat (ORLADEYO™) is an orally administered kallikrein inhibitor, which has been developed by BioCryst Pharmaceuticals for hereditary angioedema (HAE). The inhibition of kallikrein by berotralstat decreases the production of bradykinin, which prevents the localised tissue oedema that occurs during attacks of HAE. Berotralstat has been approved in the USA, and subsequently in Japan, for prophylaxis to prevent attacks of HAE in adults and paediatric patients aged 12 years or older. This article summarises the milestones in the development of berotralstat leading to this first approval for prophylaxis to prevent attacks of HAE.
