About PROCYSBI
PROCYSBI is approved in the United States for the treatment of nephropathic cystinosis in adults and children 2 years of age and older.  In Europe, PROCYSBI gastro-resistant hard capsules of cysteamine (as mercaptamine bitartrate) receivedEuropean Commission approval as an orphan medicinal product in September 2013 for the treatment of proven nephropathic cystinosis.

PROCYSBI acts within the lysosome, converting cystine into cysteine and a cysteine-cysteamine mixed disulfide, both of which can exit the lysosome in patients with cystinosis.  Adherence to treatment regimens is associated with improved outcomes, but the timing of doses is critical, as cystine levels can rise quickly if patients delay, miss, or stop taking their prescribed treatment regimen.  PROCYSBI is contraindicated in patients with a hypersensitivity to cysteamine or penicillamine.  The most commonly reported side effects are vomiting, nausea, abdominal pain, breath odor, diarrhea, skin odor, fatigue, rash and headache.

About Nephropathic Cystinosis
Nephropathic cystinosis is an inherited autosomal-recessive disease affecting lysosomal storage processes within cells; the amino acid cystine is not transported out of the lysosome, but instead accumulates and eventually crystallizes within the lysosomal lumen.  Without treatment, high intracellular cystine concentrations can occur in virtually all organs and tissues, leading to irreversible cellular damage, progressive multi-organ failure and death.

About QUINSAIR
QUINSAIR is a proprietary inhaled formulation of levofloxacin, approved in the EU and in Canada for the management of chronic pulmonary infections due to Pseudomonas aeruginosa in adult patients with cystic fibrosis.  QUINSAIR, a twice-daily treatment, contains an aerosolized form of levofloxacin, a broad-spectrum fluoroquinolone antibiotic with proven activity against a wide range of both gram-negative and gram-positive bacteria.  The fluoroquinolones rapidly inhibit replication and transcription of bacterial DNA, which leads to bacterial cell death.  QUINSAIR is not approved in the United States.

QUINSAIR is contraindicated in patients with hypersensitivity to levofloxacin, a history of tendon disorders related to fluoroquinolones, epilepsy or who may be pregnant or breast feeding.  The safety profile of QUINSAIR has been evaluated in two double-blind, placebo-controlled studies and in an active comparator study in which the most frequently reported adverse reactions were cough/productive cough, dysgeusia and fatigue/asthenia.

About Cystic Fibrosis
Cystic fibrosis is a rare, life-threatening, genetic disease affecting an estimated 21,000 adults in Europe and Canada.  Cystic fibrosis causes persistent lung infections due to the buildup of thick, sticky mucus in the lungs and progressively limits the patient's ability to breathe.  The lung infections are mostly caused by bacteria with 75 percent of cystic fibrosis patients suffering from chronic pseudomonas aeruginosa infections.
