Dornase alfa, sold under the brand name Pulmozyme, is used for the treatment of cystic fibrosis. [3] It is a recombinant human deoxyribonuclease I (rhDNase), an enzyme which selectively cleaves DNA. [3] Dornase alfa hydrolyzes the DNA present in sputum/mucus and reduces viscosity in the lungs, promoting improved clearance of secretions. [3] It is produced in Chinese hamster ovary cells. [3]
Dornase alfa is indicated for the management of people with cystic fibrosis to improve pulmonary function. [3]
Dornase alfa is an orphan drug. [4]
Dornase alfa has been shown to improve lung function in non-cystic fibrosis pre-term infants atelectasis. [5] [6]
Cystic fibrosis (CF) is a rare genetic disorder that affects mostly the lungs, but also the pancreas, liver, kidneys, and intestine. The hallmark feature of CF is the accumulation of thick mucus in different organs. Long-term issues include difficulty breathing and coughing up mucus as a result of frequent lung infections. Other signs and symptoms may include sinus infections, poor growth, fatty stool, clubbing of the fingers and toes, and infertility in most males. Different people may have different degrees of symptoms.
Bronchiectasis is a disease in which there is permanent enlargement of parts of the airways of the lung. Symptoms typically include a chronic cough with mucus production. Other symptoms include shortness of breath, coughing up blood, and chest pain. Wheezing and nail clubbing may also occur. Those with the disease often get lung infections.
Deoxyribonuclease refers to a group of glycoprotein endonucleases which are enzymes that catalyze the hydrolytic cleavage of phosphodiester linkages in the DNA backbone, thus degrading DNA. The role of the DNase enzyme in cells includes breaking down extracellular DNA (ecDNA) excreted by apoptosis, necrosis, and neutrophil extracellular traps (NET) of cells to help reduce inflammatory responses that otherwise are elicited. A wide variety of deoxyribonucleases are known and fall into one of two families, which differ in their substrate specificities, chemical mechanisms, and biological functions. Laboratory applications of DNase include purifying proteins when extracted from prokaryotic organisms. Additionally, DNase has been applied as a treatment for diseases that are caused by ecDNA in the blood plasma. Assays of DNase are emerging in the research field as well.
Lactoferrin (LF), also known as lactotransferrin (LTF), is a multifunctional protein of the transferrin family. Lactoferrin is a globular glycoprotein with a molecular mass of about 80 kDa that is widely represented in various secretory fluids, such as milk, saliva, tears, and nasal secretions. Lactoferrin is also present in secondary granules of PMNs and is secreted by some acinar cells. Lactoferrin can be purified from milk or produced recombinantly. Human colostrum has the highest concentration, followed by human milk, then cow milk (150 mg/L).
Bleomycin is a medication used to treat cancer. This includes Hodgkin's lymphoma, non-Hodgkin's lymphoma, testicular cancer, ovarian cancer, and cervical cancer among others. Typically used with other cancer medications, it can be given intravenously, by injection into a muscle or under the skin. It may also be administered inside the chest to help prevent the recurrence of a pleural effusion due to cancer; however talc is better for this.
Cystic fibrosis transmembrane conductance regulator (CFTR) is a membrane protein and anion channel in vertebrates that is encoded by the CFTR gene.
Seliciclib is an experimental drug candidate in the family of pharmacological cyclin-dependent kinase (CDK) inhibitors that preferentially inhibit multiple enzyme targets including CDK2, CDK7 and CDK9, which alter the growth phase or state within the cell cycle of treated cells. Seliciclib is being developed by Cyclacel.This is a phase II, dose ranging, multicenter, randomized, double-blind, placebo-controlled study.
Deoxyribonuclease I, is an endonuclease of the DNase family coded by the human gene DNASE1. DNase I is a nuclease that cleaves DNA preferentially at phosphodiester linkages adjacent to a pyrimidine nucleotide, yielding 5'-phosphate-terminated polynucleotides with a free hydroxyl group on position 3', on average producing tetranucleotides. It acts on single-stranded DNA, double-stranded DNA, and chromatin. In addition to its role as a waste-management endonuclease, it has been suggested to be one of the deoxyribonucleases responsible for DNA fragmentation during apoptosis.
Arylsulfatase B is an enzyme associated with mucopolysaccharidosis VI.
Miglustat, sold under the brand name Zavesca among others, is a medication used to treat type I Gaucher disease and Pompe disease.
Angiotensin II receptor type 2, also known as the AT2 receptor is a protein that in humans is encoded by the AGTR2 gene.
Hypothiocyanite is the anion [OSCN]− and the conjugate base of hypothiocyanous acid (HOSCN). It is an organic compound part of the thiocyanates as it contains the functional group SCN. It is formed when an oxygen is singly bonded to the thiocyanate group. Hypothiocyanous acid is a fairly weak acid; its acid dissociation constant (pKa) is 5.3.
The respiratory tract antimicrobial defense system is a layered defense mechanism which relies on components of both the innate and adaptive immune systems to protect the lungs and the rest of the respiratory tract against inhaled microorganisms.
Fibrosing colonopathy is a disease that arises in people with cystic fibrosis treated with high doses of pancreatic enzyme supplements. Symptoms are non-specific with abdominal pain, abdominal swelling, vomiting, and constipation.
Ivacaftor is a medication used to treat cystic fibrosis in people with certain mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene, who account for 4–5% cases of cystic fibrosis. It is also included in combination medications, lumacaftor/ivacaftor, tezacaftor/ivacaftor, and elexacaftor/tezacaftor/ivacaftor which are used to treat people with cystic fibrosis.
Nintedanib, sold under the brand names Ofev and Vargatef, is an oral medication used for the treatment of idiopathic pulmonary fibrosis and along with other medications for some types of non-small-cell lung cancer.
Protalix BioTherapeutics is an Israeli pharmaceutical company that manufactures a plant-based enzyme, taliglucerase alfa, which has received U.S. Food and Drug Administration approval for the treatment of Gaucher disease.
Tezacaftor is a drug used for the treatment of cystic fibrosis (CF) in people six years and older, who have a F508del mutation, the most common type of mutation in the CFTR gene. It is sold as a fixed-dose combination with ivacaftor under the brand name Symdeko. It was approved by the U.S. FDA in 2018. The combination of elexacaftor, tezacaftor, and ivacaftor is being sold as Trikafta.
Elexacaftor/tezacaftor/ivacaftor, sold under the brand names Trikafta (US) and Kaftrio (EU), is a fixed-dose combination medication used to treat cystic fibrosis. Elexacaftor/tezacaftor/ivacaftor is composed of a combination of ivacaftor, a chloride channel opener, and elexacaftor and tezacaftor, CFTR modulators.
Olipudase alfa, sold under the brand name Xenpozyme, is a medication used for the treatment of non-central nervous system (CNS) manifestations of acid sphingomyelinase deficiency (ASMD) type A/B or type B.
