MONTREAL, Oct. 29, 2018 — Knight Therapeutics Inc. (TSX:GUD) (“Knight”), a leading Canadian specialty pharmaceutical company, announced today the commercial availability of PROBUPHINE™ (buprenorphine hydrochloride subdermal implant), for the management of opioid dependence in patients clinically stabilized on no more than 8 mg of sublingual buprenorphine in combination with counseling and psychosocial support1. Knight has the exclusive right to distribute PROBUPHINE in Canada under a license agreement with Titan Pharmaceuticals, Inc. (NASDAQ:TTNP).

“Probuphine offers new hope for those struggling with the issues of compliance, burden and stigmatization that often accompanies opioid dependence,” said Jonathan Ross Goodman, Chief Executive Officer of Knight. “This is a devastating public health crisis and we are proud to be at the forefront of helping improve the lives of those in need.” 

“The approval of Probuphine by Health Canada earlier this year was a milestone and we look forward to supporting our partner Knight Therapeutics in this next phase,” said Titan President and CEO Sunil Bhonsle. “The commercial launch of Probuphine provides the Canadian medical community with a novel, long-term treatment alternative that can provide benefits to many patients suffering from this disease.”


PROBUPHINE™ is the only subdermal implant designed to deliver buprenorphine continuously for 6 months following a single treatment. PROBUPHINE™ was developed using ProNeura™, a continuous drug delivery system developed by Titan Pharmaceuticals Inc. and consists of a small, solid implant made from a mixture of ethylene-vinyl acetate (EVA) and buprenorphine. Four implants are inserted subdermally in the inner side of the patient’s upper arm by a healthcare professional through an in-office procedure and removed in a similar manner at the end of the treatment period.  PROBUPHINE™ must be inserted and removed by a healthcare professional who has successfully completed a live training program, the PROBUPHINE Education Program.  Knight Therapeutics Inc. obtained Health Canada approval for PROBUPHINE™ in April 2018, the first buprenorphine implant for the long-term maintenance treatment of opioid addiction.
