Teijin : Starts Exclusive Sales of Merzs Xeomin Botulinum Toxin Type A in Japan


Tokyo, JapanTeijin Pharma Limited, the core company of the Teijin Groups healthcare business, announced today that it starts exclusive sales of Xeomin (incobotulinumtoxinA) for intramuscular injection in 50, 100 or 200 units on December 4 for the treatment of upper limb spasticity. The drugs have been listed in the National Health Insurance (NHI) drug price list on November 18.

Xeomin is effective in treating peripheral cholinergic nerve endings by weakening the contraction of voluntary muscles, and it relieves muscle tone by inhibiting the release of a neurotransmitter called acetylcholine. The highly purified neurotoxin, the only active ingredient in Xeomin, is made by removing complexing proteins from botulinum toxin type A, which is produced by Clostridium botulinum, using purification technology developed by Merz Pharma GmbH & Co. KGaA. The lack of complexing proteins enables Xeomin to reduce the production of neutralizing antibodies capable of lowering efficacy. A significant improvement in the modified ashworth scale (MAS) score of wrist flexion was observed in the phase-III clinical trials in Japan.

Teijin Pharma signed an exclusive license and co-development agreement for Xeomin in Japan with Merz Pharma GmbH & Co. KGaA in 2017 and was granted approval by Japans Ministry of Health, Labor and Welfare (MHLW) to market it for the treatment of upper limb spasticity.

Upper limb spasticity is a symptom of upper motor neuron syndrome, which is expressed mainly by increased muscle tone of upper limbs and the hyperexcitability of the stretch reflex as a sequela of stroke. The main symptoms are motor paralysis, hyperflexion, appearance of pathological reflexes, and sensory disturbances that complicate or impede activities in daily living.

Conventional treatment of upper limb spasticity includes physical rehabilitation and the use of oral muscle relaxants or neuromuscular blockers such as botulinum toxin type A.

Teijin Pharma already provides various pharmaceuticals including osteoporosis treatment and medical devices such as sonic accelerated fracture healing system that supports patients suffering from musculoskeletal diseases. The company has also developed motor functions rehabilitation products such as electric stimulation device and portable robotic arm that supports the rehabilitation of paralyzed upper limbs. Teijin Pharma continues to contribute to enhancing the quality of life (QOL) of patients by providing new treatment options for diseases with high unmet needs.
