Protalix BioTherapeutics Enrolls First Patient in Phase II Clinical Trial of OPRX-106 for the Treatment of Ulcerative Colitis
CARMIEL,
“With the enrollment of the first patient in our OPRX-106 phase II trial, clinical studies are now underway for our three lead assets,” said Mr.
The phase II clinical trial is a randomized, open label, 2-arm study of OPRX-106 in 20 patients with active mild to moderate ulcerative colitis. Patients will be randomized to receive 2 mg or 8 mg of OPRX-106 administered orally, once daily, for 8 weeks. The primary endpoint of the study is safety, including monitoring for adverse events following daily administration of the drug. Key efficacy endpoints include relevant disease parameters of the drug, including Mayo score and rectal bleeding. If successful, OPRX-106 will be the first ever oral enzyme treatment as currently there are no other oral enzyme treatments available.
The Company completed a phase I clinical trial of OPRX-106 in 15 healthy volunteers, and the drug was found to be safe and well tolerated. The results of the phase I clinical trial were announced in August 2015. Immunomodulatory effect was observed, including activation of T Regulatory cells showing biological activity in the gut. In addition, early efficacy signals of OPRX-106 have been demonstrated in preclinical studies using inflammatory bowel disease immune-mediated mouse models. The results of the preclinical studies show that OPRX-106 attributes to a positive change in symptoms and in serum levels of anti-inflammatory markers.
