Group A β-hemolytic Streptococcal Pharyngitis: An Updated Review

Review

Author: Leong, Kin F. ; Barankin, Benjamin ; Leung, Alexander K.C. ; Lam, Joseph M. ; Hon, Kam L.

Background::

Group A ß-hemolytic Streptococcus (GABHS) is the leading bacterial cause of acute pharyngitis in children and adolescents worldwide.

Objective::

This article aims to familiarize clinicians with the clinical manifestations, evaluation, diagnosis, and management of GABHS pharyngitis.

Methods::

A search was conducted in December 2022 in PubMed Clinical Queries using the key term “group A β-hemolytic streptococcal pharyngitis”. This review covers mainly literature published in the previous ten years.

Results::

Children with GABHS pharyngitis typically present with an abrupt onset of fever, intense pain in the throat, pain on swallowing, an inflamed pharynx, enlarged and erythematous tonsils, a red and swollen uvula, enlarged tender anterior cervical lymph nodes. As clinical manifestations may not be specific, even experienced clinicians may have difficulties diagnosing GABHS pharyngitis solely based on epidemiologic or clinical grounds alone. Patients suspected of having GABHS pharyngitis should be confirmed by microbiologic testing (e.g., culture, rapid antigen detection test, molecular point-of-care test) of a throat swab specimen prior to the initiation of antimicrobial therapy. Microbiologic testing is generally unnecessary in patients with pharyngitis whose clinical and epidemiologic findings do not suggest GABHS. Clinical score systems such as the Centor score and McIssac score have been developed to help clinicians decide which patients should undergo diagnostic testing and reduce the unnecessary use of antimicrobials. Antimicrobial therapy should be initiated without delay once the diagnosis is confirmed. Oral penicillin V and amoxicillin remain the drugs of choice. For patients who have a non-anaphylactic allergy to penicillin, oral cephalosporin is an acceptable alternative. For patients with a history of immediate, anaphylactic-type hypersensitivity to penicillin, oral clindamycin, clarithromycin, and azithromycin are acceptable alternatives.

Conclusion::

Early diagnosis and antimicrobial treatment are recommended to prevent suppurative complications (e.g., cervical lymphadenitis, peritonsillar abscess) and non-suppurative complications (particularly rheumatic fever) as well as to reduce the severity of symptoms, to shorten the du-ration of the illness and to reduce disease transmission.

The crosstalk between efflux pump and resistance gene mutation in Helicobacter pylori

Article

Author: Wang, Youhua ; Li, Zhen ; Gong, Xiaoling ; Yong, Xie ; Liu, Dongsheng ; An, Ying

Efflux pumps play a crucial role in the development of antibiotic resistance. The aim of this study was to investigate the relationship between efflux pump gene expression and resistance gene mutations in Helicobacter pylori. Twenty-six clinical strains with varying resistance characteristics were selected for further experiment. Seven susceptible strains were induced to become resistant, and the expression of efflux pump genes and point mutations were recorded. Four susceptible strains were selected to undergo candidate mutation construction, and changes in efflux pump gene expression were detected. Efflux pump knockout strains were constructed, and their effects on preventing and reversing antibiotic resistance gene mutations were assessed. Results showed that the expression of efflux pump genes hefA and hefD was significantly higher in the multidrug-resistant group compared to other groups. During the process of antibiotic-induced resistance, efflux pump gene expression did not exhibit a steady increase or decrease. Strains with the A2143G or A2142G point mutations in 23S rRNA exhibited lower hefA gene expression. Strains with mutations at 87K/91N, 87N/91 G, 87K/91D, or 87N/91Y in gyrA and the 194insertA mutation in rdxA showed higher hefA gene expression compared to the wild-type strain. During the process of antibiotic-induced resistance, the strain with the knockout of the efflux pump gene hefA developed mutations in the 23S rRNA, gyrA, or rdxA genes later compared to the wild-type strain. Knockout of the efflux pump gene could reverse the phenotypic resistance to clarithromycin or metronidazole in some strains but had no effect on reverse resistance gene mutation. This study suggested that different resistance gene point mutations may have varying effects on efflux pump gene expression. Knockout of the efflux pump gene can delay or prevent antibiotic resistance gene mutations to some extent and can reverse phenotypic resistance to clarithromycin and metronidazole in certain strains.

A case of acquired transient bleeding diathesis associated with acquired platelet storage pool deficiency and defective thromboxane A2 production

Article

Author: Bossi, Elena ; Cattaneo, Marco ; Femia, Eti Alessandra ; Clerici, Bianca ; Fioretti, Antonella ; Ghali, Claudia ; Scavone, Mariangela ; Podda, Gian Marco

Acquired disorders of platelet function are an underdiagnosed cause of bleeding tendency. A 14-year-old girl developed moderate mucocutaneous bleeding two weeks after a Mycoplasma pneumoniae infection successfully treated with clarithromycin. The patient was referred to us 7 months later for laboratory investigation of the persisting bleeding diathesis. The patient's personal and family histories were negative for bleeding disorders. Complete blood count, von Willebrand Factor levels and coagulation tests were normal; platelet aggregation, ATP secretion, δ-granules content and serum thromboxane B2 levels were defective. At follow-up visits, laboratory parameters and the bleeding diathesis progressively normalized within 2 years. The patient's condition is compatible with a diagnosis of acquired Storage Pool Deficiency (SPD), associated with defective thromboxane A2 production. To our knowledge, this is the first case of acquired, transient SPD with spontaneous remission. The pathogenic role of Mycoplasma pneumoniae infection or clarithromycin is possible, albeit uncertain.

Phathom Pharmaceuticals to Present VOQUEZNA® Data at the American College of Gastroenterology (ACG) 2024 Annual Meeting

FLORHAM PARK, N.J., Oct. 27, 2024 (GLOBE NEWSWIRE) -- Phathom Pharmaceuticals, Inc. (Nasdaq: PHAT), a biopharmaceutical company focused on developing and commercializing novel treatments for gastrointestinal (GI) diseases, today announced that the company will present data from multiple investigational studies for its first-in-class treatment VOQUEZNA® (vonoprazan) tablets at the American College of Gastroenterology (ACG) 2024 Annual Scientific Meeting, being held October 25-30 in Philadelphia, PA. VOQUEZNA is approved for the relief of heartburn associated with Non-Erosive Gastroesophageal Reflux Disease (Non-Erosive GERD), for the treatment of all severities of Erosive Esophagitis, commonly referred to as Erosive GERD, and relief of related heartburn, and in combination with antibiotics for the eradication of Helicobacter pylori (H. pylori) infection.1 VOQUEZNA is the first and only U.S. Food and Drug Administration (FDA)-approved potassium-competitive acid blocker (PCAB).2 Evaluating On-Demand VOQUEZNA Treatment from the PHALCON-NERD-201 Trial3In an oral presentation being presented Monday, October 28 at ACG, Ronnie Fass, M.D., director of the Division of Gastroenterology and Hepatology and medical director of the Digestive Health Center at MetroHealth in Cleveland, Ohio, and lead investigator of the PHALCON-NERD-201 trial, will provide results from a post-hoc analysis of the Phase 2 study. This research, recognized with the ACG Outstanding Research Award in the ‘Esophagus’ category, evaluated the efficacy of As Needed (On-Demand) dosing of VOQUEZNA, compared to placebo, for relief of episodic heartburn in participants with Non-Erosive GERD following a 4-week VOQUEZNA daily dosing “run-in” period. As previously reported, the primary analysis of the study demonstrated that all three VOQUEZNA doses tested (10 mg, 20 mg and 40 mg) had higher percentages of heartburn completely relieved within three hours of dosing and sustained for 24 hours, with significant differences reported as early as one hour. Use of As Needed dosing in this population is investigational as VOQUEZNA has been neither evaluated nor approved by the FDA as an As Needed treatment for Non-Erosive GERD. To understand the practical application of As Needed dosing for VOQUEZNA, the new analysis examined daily heartburn symptom burden at baseline, during daily VOQUEZNA treatment, and upon switching to As Needed treatment after achieving symptom control during the run-in period. It also further evaluated the rate of symptom improvement upon treating new onset heartburn episodes during the As Needed dosing period.3 “As a healthcare provider, the concept of a novel As Needed dosing option for Non-Erosive GERD is highly compelling. I am pleased that ACG has recognized this data as a recipient of the ACG Outstanding Research Award, further reinforcing its importance to the GI community,” said Ronnie Fass, M.D. “The low frequency of heartburn after discontinuing daily VOQUEZNA treatment, coupled with the rapid onset of improvement following As Needed dosing, suggests that transitioning from daily dosing to As Needed treatment is a viable option for patients who previously respond well to daily therapy of VOQUEZNA. These promising results warrant further investigation in a larger and extended As Needed study period.” The double-blind, placebo-controlled PHALCON-NERD Phase 2 study randomized 207 patients who were eligible for On-Demand (“As Needed”) treatment following a 4-week daily dosing run-in period in which patients received VOQUEZNA 20 mg once-daily. Patients without heartburn in the last seven days of the run-in period were evenly randomized to receive 10 mg, 20 mg or 40 mg of VOQUEZNA, or placebo, for six weeks. Results of the study were published in Alimentary Pharmacology & Therapeutics in September 2023.4 Results:3 Patients eligible for the On-Demand period (n=207) were highly symptomatic with a reported mean of 16.1% [95% CI: (13.5%, 18.7%)] heartburn-free days during screening. Heartburn-free days increased during the run-in period to a mean of 82.9% [95% CI: (80.4%, 85.4%)] and remained well above pre-treatment levels (means 71% to 75%) throughout the six-week On-Demand period.The difference in the improvement of treated heartburn episodes between the active and placebo groups became evident within the first hour of dosing (10 mg [75.5%, p<0.0001], 20 mg [69.1%, p = 0.0010], 40 mg [75.5%, p<0.0001], placebo [57.0%]).Over 90% of heartburn episodes treated with VOQUEZNA improved within two hours. Non-Erosive GERD is the largest category of GERD and is characterized by reflux-related symptoms in the absence of esophageal mucosal erosions. An estimated 45 million U.S. adults are living with Non-Erosive GERD, and approximately 15 million are treated with a prescription medicine annually. Despite longstanding treatment options, many patients continue to suffer from heartburn symptoms. As Needed dosing is a unique and differentiated dosing regimen for which proton pump inhibitors (PPIs), a mainstay of GERD treatment, are not approved in the U.S.5 In July 2024, VOQUEZNA was approved by the FDA as a daily dosing treatment for the relief of heartburn associated with Non-Erosive GERD in adults.1 Nocturnal GERD Symptoms in Non-Erosive GERD6 In a poster presentation on Monday, October 28 at ACG, which has received ACG’s Presidential Poster Award, Dr. Catiele Antunes, M.D., Yale New Haven Hospital, will present data looking at the common, yet infrequently evaluated, nocturnal symptoms among patients with Non-Erosive GERD. The study included an exploratory analysis of a validated patient-reported outcomes scale, the Nocturnal Gastro-esophageal reflux disease Symptom Severity and Impact Questionnaire (N-GSSIQ), to determine the severity, morning impact, and concern about nocturnal GERD. “We are very pleased to continue to add to the body of clinical research evaluating the potential benefits of VOQUEZNA for GERD patients,” said Eckhard Leifke, M.D., Chief Medical Officer at Phathom. “In our study, patients who experienced nocturnal GERD symptoms prior to VOQUEZNA treatment found effective and meaningful relief with daily dosing, reinforcing its potent and durable acid suppression profile in helping to address both daytime and nighttime heartburn. While these findings are exploratory, they show promise for the many individuals suffering from nocturnal GERD symptoms.” Results:6 Among 772 subjects, the mean percentage of heartburn-free nights during the screening period was 29.6%, 25.8% and 31.1%, for patients randomized to placebo, VOQUEZNA 10 mg and 20 mg, respectively.After 4 weeks, the least-square (LS) mean percentage of heartburn-free nights was significantly better with 59.9% for VOQUEZNA 10 mg (LS mean difference=16.5%, p<0.0001 vs. placebo), and 56.4% for VOQUEZNA 20 mg (LS mean difference=13.1%, p<0.0001 vs. placebo), compared to 43.3% for placebo. The median percentage of heartburn-free nights was 70.4% for VOQUEZNA 10 mg and 71.0% for VOQUEZNA 20 mg, compared to 45.5% for placebo.N-GSSIQ scores showed significant improvement with VOQUEZNA compared to placebo in total score (LS mean difference vs. placebo of -2.9 and -1.8 for VOQUEZNA 10 mg and 20 mg, respectively; p<0.005 for both comparisons), nocturnal symptom severity (LS mean difference vs. placebo of -5.4 and -3.5 for VOQUEZNA 10 mg and 20 mg; p<0.001 for both comparisons), and concern about nocturnal GERD (LS mean difference vs. placebo of -2.0 for both VOQUEZNA 10 mg and 20 mg; p<0.0001). In addition to these data presentations, Phathom will sponsor a product theater highlighting VOQUEZNA as an approved treatment for GERD and will also have a presence on the exhibit floor at booth #757 throughout the conference. Following the conclusion of ACG 2024, the abstracts will be posted to the publications and scientific section of the Phathom company website.

IMPORTANT SAFETY INFORMATION CONTRAINDICATIONS VOQUEZNA is contraindicated in patients with a known hypersensitivity to vonoprazan or any component of VOQUEZNA, or in patients receiving rilpivirine-containing products. For information about contraindications of antibacterial agents (clarithromycin and amoxicillin) indicated in combination with VOQUEZNA, refer to the Contraindications section of the corresponding prescribing information. WARNINGS AND PRECAUTIONS Presence of Gastric Malignancy: In adults, symptomatic response to therapy with VOQUEZNA does not preclude the presence of gastric malignancy. Consider additional follow-up and diagnostic testing in patients who have a suboptimal response or an early symptomatic relapse after completing treatment with VOQUEZNA. In older patients, also consider endoscopy. Acute Tubulointerstitial Nephritis: Acute tubulointerstitial nephritis (TIN) has been reported with VOQUEZNA. If suspected, discontinue VOQUEZNA and evaluate patients with suspected acute TIN. Clostridioides difficile-Associated Diarrhea: Published observational studies suggest that proton pump inhibitors (PPIs) may be associated with an increased risk of Clostridioides difficile-associated diarrhea (CDAD), especially in hospitalized patients. VOQUEZNA may also increase the risk of CDAD. Consider CDAD in patients with diarrhea that does not improve. Use the shortest duration of VOQUEZNA appropriate to the condition being treated. CDAD has been reported with use of nearly all antibacterial agents. For more information specific to antibacterial agents (clarithromycin and amoxicillin) indicated for use in combination with VOQUEZNA, refer to Warnings and Precautions section of the corresponding prescribing information. Bone Fracture: Several published observational studies suggest that PPI therapy may be associated with an increased risk for osteoporosis-related fractures of the hip, wrist, or spine, especially in patients receiving high dose (multiple daily doses) and long-term therapy (a year or longer). Bone fracture, including osteoporosis-related fracture, has also been reported with vonoprazan. Use the shortest duration of VOQUEZNA appropriate to the condition being treated. Patients at risk for osteoporosis-related fractures should be managed according to the established treatment guidelines. Severe Cutaneous Adverse Reactions (SCAR): Severe cutaneous adverse reactions, including Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) have been reported with VOQUEZNA. Discontinue VOQUEZNA at the first signs or symptoms of SCAR or other signs of hypersensitivity and consider further evaluation. Vitamin B12 (Cobalamin) Deficiency: Long-term use of acid-suppressing drugs can lead to malabsorption of Vitamin B12 caused by hypo- or achlorhydria. Vitamin B12 deficiency has been reported postmarketing with vonoprazan. If clinical symptoms consistent with vitamin B12 deficiency are observed in patients treated with VOQUEZNA, consider further workup. Hypomagnesemia and Mineral Metabolism: Hypomagnesemia has been reported postmarketing with vonoprazan. Hypomagnesemia may lead to hypocalcemia and/or hypokalemia and may exacerbate underlying hypocalcemia in at-risk patients. Consider monitoring magnesium levels prior to initiation of VOQUEZNA and periodically in patients expected to be on prolonged treatment, in patients taking drugs that may have increased toxicity in the presence of hypomagnesemia or drugs that may cause hypomagnesemia. Treatment of hypomagnesemia may require magnesium replacement and discontinuation of VOQUEZNA. Consider monitoring magnesium and calcium levels prior to initiation of VOQUEZNA and periodically while on treatment in patients with a preexisting risk of hypocalcemia. Supplement with magnesium and/or calcium, as necessary. If hypocalcemia is refractory to treatment, consider discontinuing VOQUEZNA. Interactions with Diagnostic Investigations for Neuroendocrine Tumors: Serum chromogranin A (CgA) levels increase secondary to drug-induced decreases in gastric acidity. The increased CgA level may cause false positive results in diagnostic investigations for neuroendocrine tumors. Temporarily discontinue VOQUEZNA treatment at least 4 weeks before assessing CgA levels and consider repeating the test if initial CgA levels are high. Fundic Gland Polyps: Use of VOQUEZNA is associated with a risk of fundic gland polyps that increases with long-term use, especially beyond one year. Fundic gland polyps have been reported with vonoprazan in clinical trials and during postmarketing use with PPIs. Most patients who developed fundic gland polyps were asymptomatic and fundic gland polyps were identified incidentally on endoscopy. Use the shortest duration of VOQUEZNA appropriate to the condition being treated. ADVERSE REACTIONS: Healing of Erosive GERD: The most common adverse reactions (≥2% of patients in the VOQUEZNA arm) include gastritis (3%), diarrhea (2%), abdominal distention (2%), abdominal pain (2%), and nausea (2%). Maintenance of Healed Erosive GERD: The most common adverse reactions (≥3% of patients in the VOQUEZNA arm) include gastritis (6%), abdominal pain (4%), dyspepsia (4%), hypertension (3%), and urinary tract infection (3%). Relief of Heartburn Associated with Non-Erosive GERD: The most common adverse reactions (≥2% of patients in the VOQUEZNA arm) include abdominal pain (2%), constipation (2%), diarrhea (2%), nausea (2%), and urinary tract infection (2%). Treatment of H. Pylori Infection (VOQUEZNA and Amoxicillin): The most common adverse reactions (≥2% in any treatment arm) include diarrhea (5%), abdominal pain (3%), vulvovaginal candidiasis (2%), nasopharyngitis (2%), dysgeusia (1%), headache (1%), and hypertension (1%). Treatment of H. Pylori Infection (VOQUEZNA, Amoxicillin and Clarithromycin): The most common adverse reactions (≥2% in any treatment arm) include dysgeusia (5%), diarrhea (4%), vulvovaginal candidiasis (3%), headache (3%), abdominal pain (2%), hypertension (2%), and nasopharyngitis (<1%). For more information on adverse reactions and laboratory changes with amoxicillin or clarithromycin, refer to Adverse Reactions section of the corresponding prescribing information. DRUG INTERACTIONS VOQUEZNA has the potential for clinically important drug interactions, including interactions with drugs dependent on gastric pH for absorption, drugs that are substrates for certain CYP enzymes, and some diagnostic tests. Avoid concomitant use of VOQUEZNA with atazanavir or nelfinavir. See full Prescribing Information for more details about important drug interactions. Consult the labeling of concomitantly used drugs to obtain further information about interactions with vonoprazan. For information about drug interactions, contraindications, and warnings and precautions of antibacterial agents (amoxicillin or clarithromycin) indicated in combination with VOQUEZNA, refer to their corresponding prescribing information. USE IN SPECIFIC POPULATIONS Lactation: Breastfeeding is not recommended during treatment. Because of the potential risk of adverse liver effects shown in animal studies with vonoprazan, advise patients not to breastfeed during treatment with VOQUEZNA. Renal Impairment: For the healing of Erosive GERD, dosage reduction is recommended in patients with severe renal impairment (eGFR < 30 mL/min). Use of VOQUEZNA is not recommended for the treatment of H. pylori infection in patients with severe renal impairment. Hepatic Impairment: For the healing of Erosive GERD, dosage reduction is recommended in patients with moderate to severe hepatic impairment (Child-Pugh Class B and C). Use of VOQUEZNA is not recommended for the treatment of H. pylori infection in patients with moderate to severe hepatic impairment.

(Nasdaq: SPRO), a multi-asset clinical-stage biopharmaceutical company, focused on identifying and developing novel treatments for rare diseases and multi-drug resistant (MDR) bacterial infections, today announced a poster presentation at IDWeek 2024, entitled “Evaluation of the Spontaneous Mutation Frequencies of SPR719 Alone and in Combination with Other Agents Used to Treat Mycobacterium avium Complex Pulmonary Disease.” The poster will be presented on Friday, October 18, 2024, in Hall J & K, at 12:15 PM - 1:30 PM Pacific Time. A copy of the poster will be available on the Spero corporate website here. SPR720 is an oral, chemically stable phosphate ester prodrug that is converted rapidly in vivo to SPR719, the active moiety. SPR719 targets the ATPase site of DNA gyrase B in mycobacteria, a mechanism that is distinct from that of other antibiotics in use for nontuberculous mycobacterium pulmonary disease (NTM-PD). The study was conducted in collaboration with Microbiologics, a leading contract research and manufacturing organization (CRMO), partnering with pharmaceutical and diagnostic companies to bring new lifesaving technology, anti-infective drugs, vaccines and therapeutics to market. “These in vitro results present an important aspect of SPR719’s activity against MAC NTM-PD,” said Chris Pillar, Ph.D., Director of Science and Operations, Microbiologics. “Resistance to antibiotics is a major health problem, particularly in diseases such as NTM-PD with long courses of treatment where resistance mechanisms can spontaneously manifest. The data presented at ID Week 2024 confirm the high potency of SPR719 against both macrolide susceptible and resistant MAC strains, with a low propensity for the spontaneous development of resistance mechanisms. Importantly, these characteristics were maintained in the combination with current standard of care (SOC) antibiotics used in the treatment of NTM-PD, and presented lower resistance compared to SOC antibiotics alone.” Poster Presentation Highlights Activity of SPR719 and current standard of care antibiotics (clarithromycin, ethambutol and rifampin) were evaluated for potency (MIC concentration testing), propensity for the spontaneous development of drug-resistance (spontaneous mutation frequency [SMF] assay) and potential interactions for combination treatment (antibacterial synergy testing) against both macrolide susceptible and macrolide resistant mycobacterium avian complex (MAC) strains.SPR719 selection concentrations as low as 2-fold the MIC suppressed the emergence of resistance against both tested MAC isolates. Mutation frequencies for SPR719 against MAC observed in this study were about 3 orders of magnitude lower than those for SOC comparators tested in this study.In-line with previous reports, SPR719 demonstrated a high degree of potency with MIC values of 2 ug/mL for both macrolide susceptible and resistant strains. No resistant colonies were isolated when SPR719 was combined with clarithromycin or ethambutol in the SMF assay.In summary, SPR719 had a low propensity for resistance development in this study and showed no instances of antagonism when combined with clarithromycin or ethambutol, highlighting its potential for use in prolonged combination regimens typically required to treat NTM-PD. About Nontuberculous Mycobacterium Pulmonary Disease (NTM-PD) NTM-PD, also known as NTM lung disease, is caused by bacteria naturally found in soil, dust, and water. These bacteria are members of the Mycobacterium family and are distinct from tuberculosis and leprosy. The most common bacteria that cause of NTM infections is the Mycobacterium avium complex (MAC). NTM is a growing global health concern with significant unmet medical needs. Although rare, the incidence of NTM pulmonary disease is increasing worldwide. It is estimated that approximately 130,000 patients suffer from NTM in the U.S. and Europe, a figure that is growing at a rate of 8% annually. Patients with NTM lung disease experience progressive symptoms, lung damage, and reduced quality of life due to chronic symptoms and impaired lung function. NTM infections can occur after surgery, trauma, injections, or exposure to contaminated water. Prevention involves effective water management programs in healthcare facilities, and treatment typically requires consultation with infectious disease or pulmonary specialists. Patients currently have limited treatment options for NTM lung disease.

Vertex Highlights First Oral Presentation of Phase 3 Clinical Data of the Vanza Triple and New Data on Long-Term Impact of TRIKAFTA® at the North American Cystic Fibrosis Conference

BOSTON--( BUSINESS WIRE )-- Vertex Pharmaceuticals Incorporated (Nasdaq: VRTX) today announced the first accepted medical presentations of the Phase 3 data on the investigational once daily vanzacaftor/tezacaftor/deutivacaftor (“vanza triple”) — the potential next-in-class triple combination medicine — will take place at the North American Cystic Fibrosis Conference (NACFC). Vertex also announced presentations describing long-term outcomes in people with cystic fibrosis (CF) ages 2 to 11 years taking TRIKAFTA ® , demonstrating consistent and sustained improvements across multiple measures of disease. “ TRIKAFTA has transformed the treatment of CF in the 5 years since its approval, changing the outlook for patients with CF,” said Carmen Bozic, M.D., Executive Vice President, Global Medicines Development and Medical Affairs, and Chief Medical Officer at Vertex. “ Toward our goal to bring all eligible patients to normal levels of CFTR function, we have made global regulatory submissions for our next-in-class vanza triple combination medicine for patients with CF aged 6 years and older. We are excited to bring this promising new medicine, which has the potential to deliver even greater improvements in sweat chloride, to patients with CF.” Data on the Investigational Once Daily Next-in-Class Triple Combination Therapy, vanzacaftor/tezacaftor/deutivacaftor Vertex will present data on the vanza triple in an oral presentation and two posters on Friday, September 27. This is the first time that the clinical data from the Phase 3 clinical trials of the vanza triple in patients 6 years and older with CF have been accepted for presentation at a medical meeting. These data formed the basis of global regulatory submissions. “ The additional, significant reductions in sweat chloride we see in the vanza triple clinical trials are noteworthy. I believe this improvement in CFTR function may lead to important benefits for people with CF,” said Claire L. Keating, M.D., Co-Director of the Gunnar Esiason Adult Cystic Fibrosis and Lung Program at Columbia University. “ If approved, as a clinician, I’m looking forward to being able to offer patients an option, with once daily dosing, that could advance the treatment for people living with CF.” Data from the Phase 3 clinical studies of the vanza triple will be presented in the following sessions: “ Vanzacaftor/Tezacaftor/Deutivacaftor (VNZ Triple) in Adolescents and Adults with CF: Results from Two Randomized, Active-Controlled Phase 3 Trials,” will be an oral presentation during a session entitled: “Cutting Edge Research: What’s New” on Friday, September 27, from 10:15 a.m. to 12:15 p.m. EDT and be a poster presentation on Friday, September 27, from 1:15-2:15 p.m. EDT. “ Safety and Efficacy of Vanzacaftor/Tezacaftor/Deutivacaftor (VNZ Triple) in Children 6 Through 11 Years of Age with Cystic Fibrosis,” will be a poster presentation on Friday, September 27, from 1:15-2:15 p.m. EDT. The vanza triple was granted Fast Track and Orphan Drug Designations from the U.S. Food and Drug Administration (FDA) for the treatment of CF and has been submitted for regulatory approval in the U.S., Canada, U.K., EU, Switzerland, Australia and New Zealand. Vertex has been assigned a Prescription Drug User Fee Act (PDUFA) date by the FDA of January 2, 2025, for this submission. The vanza triple has not been approved by any global health authority. Long-Term Benefits of TRIKAFTA ® Vertex will present new data on TRIKAFTA ® from long-term (96 week and 192 week) studies in patients ages 2-11 years old that reinforce the sustained benefit seen in studies in older people with CF. Specifically, that early treatment with TRIKAFTA ® is associated with sustained improvements in lung function. These new data demonstrate that in these young children, TRIKAFTA ® could also lead to improved exocrine pancreatic function over time. The data presented at NACFC highlight the safety and tolerability of TRIKAFTA ® , which were generally consistent with the established safety profile. “ I have seen first-hand the positive long-term impact that improvement of CFTR function by TRIKAFTA can have on patients’ clinical outcomes. These improvements are particularly striking for me as a physician caring for young children, where improvements in things like lung function, pancreatic function and quality of life are so meaningful,” said Professor Marcus A. Mall, M.D., Professor and Chair of the Department of Pediatric Respiratory Medicine, Immunology and Critical Care Medicine and Cystic Fibrosis Center at Charité - Universitätsmedizin Berlin. Vertex will have four poster presentations that include clinical trial and real-world evidence data, three specifically on TRIKAFTA ® and one showing sustained benefits from KALYDECO ® , which is approved for treatment in the youngest ages. “ Long-term safety and efficacy of elexacaftor/tezacaftor/ivacaftor in children 2 years and older with cystic fibrosis and at least one F508del allele: 96-week results from an open-label extension study,” will be a poster presentation on Friday, September 27, at 12:15-1:15 p.m. EDT. “ Long-term safety and efficacy of elexacaftor/tezacaftor/ivacaftor in children 6 years and older with cystic fibrosis and at least one F508del allele: Results from a 192-week extension study,” will be a poster presentation on Friday, September 27, at 1:15-2:15 p.m. EDT. “ Effectiveness of elexacaftor/tezacaftor/ivacaftor (ELX/TEZ/IVA) in people with cystic fibrosis and non-F508del CFTR variants: Interim results from a registry-based study,” will be a poster presentation on Friday, September 27, from 12:15-1:15 p.m. EDT. “ Long-term benefits of early ivacaftor (IVA) initiation in people with cystic fibrosis (CF),” will be a poster presentation on Friday, September 27, from 1:15-2:15 p.m. EDT. About Cystic Fibrosis Cystic fibrosis (CF) is a rare, life-shortening genetic disease affecting more than 92,000 people globally. CF is a progressive, multi-organ disease that affects the lungs, liver, pancreas, GI tract, sinuses, sweat glands and reproductive tract. CF is caused by a defective and/or missing CFTR protein resulting from certain mutations in the CFTR gene. Children must inherit two defective CFTR genes — one from each parent — to have CF, and these mutations can be identified by a genetic test. While there are many different types of CFTR mutations that can cause the disease, the vast majority of people with CF have at least one F508del mutation. CFTR mutations lead to CF by causing CFTR protein to be defective or by leading to a shortage or absence of CFTR protein at the cell surface. The defective function and/or absence of CFTR protein results in poor flow of salt and water into and out of the cells in a number of organs. In the lungs, this leads to the buildup of abnormally thick, sticky mucus, chronic lung infections and progressive lung damage that eventually leads to death for many patients. The median age of death is in the 30s, but with treatment, projected survival is improving. Learn more about the importance of sweat chloride (SwCl) in cystic fibrosis. Today Vertex CF medicines are treating over 68,000 people with CF across more than 60 countries on six continents. This represents 2/3 of the diagnosed people with CF eligible for CFTR modulator therapy. About vanzacaftor/tezacaftor/deutivacaftor (the “vanza triple”) In people with CF, mutations in the CFTR gene lead to decreased quantity and/or function of the CFTR protein channel at the cell surface. Vanzacaftor and tezacaftor are designed to increase the amount of CFTR protein at the cell surface by facilitating the processing and trafficking of the CFTR protein. Deutivacaftor is a potentiator designed to increase the channel open probability of the CFTR protein delivered to the cell surface to improve the flow of salt and water across the cell membrane. Investigational vanzacaftor/tezacaftor/deutivacaftor was granted Fast Track and Orphan Drug Designations from the U.S. Food and Drug Administration for the treatment of CF. The vanza triple will be subject to a meaningfully lower single-digit royalty obligation, compared to the rate payable on Vertex’s current CF portfolio. About TRIKAFTA ® (elexacaftor/tezacaftor/ivacaftor and ivacaftor) In people with certain types of mutations in the CFTR gene, the CFTR protein is not processed or folded normally within the cell, and this can prevent the CFTR protein from reaching the cell surface and functioning properly. TRIKAFTA ® (elexacaftor/tezacaftor/ivacaftor and ivacaftor) is an oral medicine designed to increase the quantity and function of the CFTR protein at the cell surface. Elexacaftor and tezacaftor work together to increase the amount of mature protein at the cell surface. Ivacaftor, which is known as a CFTR potentiator, is designed to facilitate the ability of CFTR proteins to transport salt and water across the cell membrane. The combined actions of elexacaftor, tezacaftor and ivacaftor help hydrate and clear mucus from the airways. TRIKAFTA ® (elexacaftor/tezacaftor/ivacaftor and ivacaftor) is a prescription medicine used for the treatment of cystic fibrosis (CF) in patients aged 2 years and older who have at least one copy of the F508del mutation, or another mutation responsive to TRIKAFTA ® , in the CFTR gene. Patients should talk to their doctor to learn if they have an indicated CF gene mutation. It is not known if TRIKAFTA ® is safe and effective in children under 2 years of age.
