LEIDEN, The Netherlands and RALEIGH, North Carolina, January 8, 2015 /PRNewswire/ --
Pharming Group NV (EURONEXT: PHARM) and Salix Pharmaceuticals, Ltd. (NASDAQ:SLXP) today announced that the first patient was treated in their Phase 2 clinical study of Ruconest®, (C1 Esterase Inhibitor [Recombinant]) 50 IU/kg, for prophylaxis in patients with hereditary angioedema (HAE).
HAE patients deficient in C1 inhibitor and with a history of at least four attacks per month are being enrolled in the randomized, double-blind study, in which 30 patients will receive Ruconest® either once or twice weekly, or placebo in each of 3 treatment periods. With the crossover design, all patients will receive each of the dosing regimens. The study will evaluate the safety and efficacy of Ruconest® when used for prophylaxis of angioedema attacks in patients with HAE.
The study will be conducted at sites in Canada, Europe, Israel, and the United States. The trial is being coordinated by principal investigators, Dr. Marco Cicardi, Professor at the University of Milan, and Dr. Marc Riedl, Associate Professor and Clinical Director of the US HAEA Angioedema Center at the University of California, San Diego.
"We are pleased to have quickly initiated the treatment phase of this important study, and look forward to its completion later in 2015," said Bruno Giannetti, MD PhD, Chief Operating Officer of Pharming.
Under the terms of the Pharming-Salix license agreement, the companies will equally share the development costs for Ruconest® for HAE prophylaxis. Pharming will receive an undisclosed milestone payment from Salix as and when FDA approval for this additional indication is given.
Important Safety Information for RUCONEST
RUCONEST® is a C1 esterase inhibitor [recombinant] indicated for the treatment of acute attacks in adult and adolescent patients with hereditary angioedema (HAE). Effectiveness in clinical studies was not established in HAE patients with laryngeal attacks.
RUCONEST® (C1 esterase inhibitor [recombinant]) is contraindicated in patients with a history of allergy to rabbits or rabbit-derived products, and patients with a history of life-threatening immediate hypersensitivity reactions to C1 esterase inhibitor preparations, including anaphylaxis.
Severe hypersensitivity reactions may occur. The signs and symptoms of hypersensitivity reactions may include hives, generalized urticaria, tightness of the chest, wheezing, hypotension, and/or anaphylaxis during or after injection of RUCONEST. Should symptoms occur, discontinue RUCONEST and administer appropriate treatment. Because hypersensitivity reactions may have symptoms similar to HAE attacks, treatment methods should be carefully considered.
Serious arterial and venous thromboembolic (TE) events have been reported at the recommended dose of plasma derived C1 esterase inhibitor products in patients with risk factors. Risk factors may include the presence of an indwelling venous catheter/access device, prior history of thrombosis, underlying atherosclerosis, use of oral contraceptives or certain androgens, morbid obesity, and immobility. Monitor patients with known risk factors for TE events during and after RUCONEST administration.
RUCONEST has not been studied in pregnant women; therefore, it should only be used during pregnancy if clearly needed.
The most common adverse reactions (incidence ≥2%) were headache, nausea, and diarrhea. The serious adverse reaction in clinical studies of RUCONEST was anaphylaxis.
Please see complete Prescribing Information for RUCONEST.
RUCONEST® (C1 Esterase Inhibitor [Recombinant]) 50 IU/kg is an injectable medicine that is used to treat acute angioedema attacks in adult and adolescent patients with hereditary angioedema (HAE). HAE is caused by a deficiency of the C1 esterase inhibitor protein, which is present in blood and helps control inflammation (swelling) and parts of the immune system. A shortage of C1 esterase inhibitor can lead to repeated attacks of swelling, pain in the abdomen, difficulty breathing and other symptoms. RUCONEST® contains C1 esterase inhibitor at 50 IU/kg.
When administered at the onset of HAE attack symptoms at the recommended dose, RUCONEST works to return a patient's C1-INH levels to normal range and quickly begins to relieve the symptoms of an HAE attack with a low recurrence of symptoms.
RUCONEST is the first and only plasma-free, recombinant C1-INH approval from the U.S. Food and Drug Administration (FDA) and was approved in July 2014.
RUCONEST has been granted Orphan Drug designation by the FDA for the treatment of acute angioedema attacks in patients with hereditary angioedema (HAE). With RUCONESTnow approved by the FDA, Salix believes this designation should provide seven years of marketing exclusivity in the United States.
Hereditary angioedema (HAE) is a genetic condition occurring between 1 in 10,000 to 1 in 50,000 people. Those with HAE experience episodes of swelling in their extremities, face and abdomen, with potentially life-threatening swelling of the airway. When it occurs in the abdomen, this swelling can be accompanied by bouts of nausea, vomiting and severe pain. Swelling in the face or extremities can be painful, disfiguring, and disabling.
HAE patients have a defect in the gene that controls production of a protein found in the blood vessels, called C1 inhibitor or C1-INH. When a person's C1-INH levels are low, fluid from blood vessels can leak into nearby connective tissues, causing severe pain and swelling and, in rare cases, death from asphyxiation from airway swelling.
