- Cystinosis is a rare, autosomal recessive disorder caused by the inability to metabolize the amino acid cystine, leading to intra-lysosomal accumulation of cystine and crystals thereof within various tissues, such as spleen, liver, lymph nodes, kidney, bone marrow, and eyes.
- Cystinosis is caused by mutations in the gene that encodes cystinosin (CTNS gene), a lysosomal-specific transporter for cystine.
- CNS gene cystinosin
- the disorder follows an autosomal recessive inheritance pattern. Because of a defect in cystinosin, cystine cannot be exported from lysosomes and therefore accumulates there. As cystine is highly insoluble, when its concentration in tissue lysosomes increases, its solubility is exceeded and crystalline precipitates are formed in almost all organs and tissues.
- cystinosis Three clinical forms of cystinosis have been described. Infantile (or nephropathic) cystinosis; intermediate (or late-onset) cystinosis; and non-nephrotic cystinosis. Infantile or nephropathic cystinosis is usually diagnosed between 6 and 18 months of age with symptoms of excessive thirst and urination, failure to thrive, rickets, and episodes of dehydration. As a consequence, important nutrients and minerals are lost in the urine. Children with cystinosis can also have an ocular manifestation of this disease, and develop crystals in their eyes (usually after one year of age) which may lead to photosensitivity. Without specific treatment, children with cystinosis develop end-stage renal failure, leading to loss of kidney function, usually between 6 and 12 years of age.
- Cystinosis is currently treated by oral administration of cysteamine in order to reduce cystine accumulation within cells.
- CYSTAGON® cysteamine bitartrate
- capsules are currently approved for the treatment of cystinosis; a delayed-release capsule (PROCYSBI® (cysteamine bitartrate) delayed-release capsules) is also available.
- cysteamine subjects with cystinosis are often given sodium citrate to treat the blood acidosis associated with the disease, as well as potassium and phosphorus supplements.
- cysteamine is administered to the eye, such as by eyedrops.
- cysteamine treatment Adhering to cysteamine treatment is cumbersome, particularly in view of the very young age of individuals suffering from this disorder. Individuals with cystinosis take oral cysteamine every 6 hours, day and night. When taken regularly, cysteamine can deplete intracellular cystine by up to 90% (as measured in circulating white blood cells), and this has been shown to reduce the rate of progression to kidney failure and transplantation. Because of the difficulty of adhering to the dosing regimen of cysteamine, reducing the dose burden for individuals with nephropathic cystinosis would be beneficial for these patients.
- Nephropathic cystinosis is associated with kidney failure. To date, the only specific treatment for nephropathic cystinosis is the sulfhydryl agent cysteamine. Cysteamine acts by converting cystine to cysteine and cysteine-cysteamine mixed disulfide, which are then both able to leave the lysosome through cystine and lysine transporters, respectively. (Gahl et al, N Engl J Med, 2002, 347:111-121.) Cysteamine has been shown to lower intracellular cystine levels, thereby reducing the rate of progression of kidney failure in individuals with nephropathic cystinosis.
- cysteamine treatment individuals with nephropathic cystinosis can develop complications in organs other than the kidneys and eyes due to the continued accumulation of cystine throughout the body. These complications can include muscle wasting, difficulty swallowing, diabetes, and hypothyroidism. Some symptoms include the inability of the kidneys to concentrate urine and allow important quantities of sodium, potassium, phosphorus, bicarbonate and substances like carnitine to be excreted in the urine. In addition, the loss of urinary electrolytes (sodium, potassium, bicarbonate, phosphorus) must be compensated in these patients.
- One clinical read-out for determining the effectiveness and appropriate dosage of cysteamine treatment involves monitoring cystine levels in white blood cells.
- cystinosis Normal individuals or individuals heterozygous for cystinosis have white blood cell cystine levels of less than 0.2 and usually below 1 nmol/l/2 cystine/mg protein, respectively. Individuals with nephropathic cystinosis have elevated white blood cell cystine levels above 2 nmol/l/2 cystine/mg protein. When taken regularly, cysteamine administration can deplete intracellular cystine by up to 90% (as measured in circulating white blood cells). Cystine levels in white blood cells are closely and frequently monitored in these patients to determine adequacy and effectiveness of drug dosing by measuring white blood cell cystine levels 5 to 6 hours after administering cysteamine.
- cysteamine therapy for nephropathic cystinosis is to keep white blood cell (e.g., leukocyte) cystine levels below 1 nmol/l/2 cystine/mg protein as measured five to six hours following administration of the drug.
- white blood cell e.g., leukocyte
- the recommended maintenance dose of cysteamine for children up to 12 years of age is 1.3 grams/m 2 /day, given in four divided doses. New patients typically initiate treatment with one-quarter to one-sixth of the maintenance dose; the dose is then raised gradually over four to six weeks to avoid or minimize any intolerance to the drug. Patients over 12 years old or over 110 pounds may be administered 2.0 grams/m 2 /day, divided four times daily; however, cysteamine doses this high are often associated with adverse events, including vomiting, anorexia, fever, diarrhea, lethargy, and rash.
- cysteamine 4 times a day is because cysteamine is only active within the body for a very short period of time not exceeding 5-6 hours. Additionally, cysteamine therapy is only effective for the treatment of nephropathic cystinosis if administered according to the above regimen day after day, indefinitely, in order to control the disease.
- cysteamine Because of the strict and cumbersome treatment regimen of cysteamine and the associated adverse gastrointestinal and central nervous system symptoms, nonadherence to cysteamine therapy remains a significant problem for patients suffering from nephropathic cystinosis, particularly among adolescent and young adult patients. By reducing the frequency of cysteamine dosing, or providing alternative treatment methods, such as those provided herein, adherence to a therapeutic regimen can therefore be easily achieved, thus resulting in better treatment efficacy and outcomes.

- Pantothenate kinase-associated neurodegeneration is an autosomal recessive disorder characterized by dystonia, dysarthria, rigidity, pigmentary retinal degeneration, and brain iron accumulation (Kruer et al, 2012, Am J Neuroradiol, 33:407-414; Zhou et al, Nat Genet, 28:345-349).
- PKAN is the most common type of neurodegeneration with brain iron accumulation (NBIA), a group of clinical disorders marked by progressive abnormal involuntary movements, alterations in muscle tone, and postural disturbances (extrapyramidal). These disorders show radiographic evidence of iron accumulation in the brain.
- PKAN is typically diagnosed by molecular genetic testing, most often after a characteristic finding on magnetic resonance imaging (MRI), called the “eye-of-the-tiger” sign, is detected.
- MRI magnetic resonance imaging
- PKAN progressive night blindness and loss of peripheral (side) vision.
- Classical PKAN develops in the first ten years of life (average age for developing symptoms is three and a half years). These children may initially be perceived as clumsy and later develop more noticeable problems with walking. Speech delay is also common. Eventually, falling becomes a frequent feature. Because of the limited ability to protect themselves during falls, children may have repeated injury to the face and chin. Many individuals with the classic form of PKAN require a wheelchair by their mid-teens (in some cases earlier). Most lose the ability to move/walk independently between 10 and 15 years after the beginning of symptoms.
- PKAN The atypical form of PKAN usually occurs after the age of ten years and progresses more slowly. The average age for developing symptoms is 13 years. Loss of independent ambulation (walking) often occurs 15 to 40 years after the initial development of symptoms.
- PKAN is caused by mutations in the PANK2 gene, which codes for the mitochondrial enzyme pantothenate kinase 2. This enzyme is part of the co-enzyme A biosynthetic pathway, catalyzing the phosphorylation of vitamin B5 or pantothenate. (Hayflick, 2003, J Neurol Sci, 207:106-107).
- Pank2 /_ mice feed a ketogenic diet show clinical signs similar to that observed in patients with PKAN, namely severe movement disorder and neurodegeneration. Pantethine administration to such mice appeared to rescue the clinical phenotype, such as improved movement, amelioration of mitochondrial dysfunctions, and extension of lifespan (Brunetti et al, 2013, Brain, p.1-12).

- Fibrates are a class of amphipathic carboxylic acids used for treatment of various metabolic disorders, including hypercholesterolemia. Fibrates, or fibric acid derivatives, are regarded as broad-spectrum lipid-modulating agents. In addition to decreasing serum triglycerides, fibrates have also been shown to be modestly effective at reducing LDL- cholesterol and raising HDL-cholesterol. Fibrates are often used in combination with statins for the treatment of hypercholesterolemia.
- Fibrates include, but are not limited to, aluminum clofibrate, bezafibrate, ciprofibrate, choline fenofibrate, clinofibrate, clofibrate, clofibride, fenofibrate, gemfibrozil, ronifibrate, and simfibrate, pemafibrate, or a pharmaceutically acceptable salt, collate, clathrate, polymorph, prodrug, or pharmaceutically active metabolite thereof.

- PPARs are a class of nuclear hormone receptor proteins that function as transcription factors regulating the expression of various gene, including genes that modulate, inter alia, carbohydrate and fat metabolism and adipose tissue differentiation. Activating the activity of PPARs induces the transcription of a number of genes, many of which facilitate lipid metabolism.
- Fibrate treatment has been associated with elevated levels of transaminases (AST and ALT) and the association appears to be dose related. (See Kobayashi et al. 2009, J Tocicol Sci, 34:377-387.) It is recommended that regular monitoring of liver function be carried out during fibrate therapy and the drug discontinued if levels persisted above three times the upper limit of the normal reference range. Due to the effects of administering a combination of pantethine and fibrate in the treatment of various disorders described herein, a lower dose of either pantethine, fibrate, or both agents are thus effective in such treatments, reducing any adverse side effects associated with administering higher doses of either or both agents.
