Ra Pharmaceuticals and Camurus Announce Exclusive License Agreement for FluidCrystal® Extended Release Formulation of Zilucoplan

CAMBRIDGE, Massachusetts and LUND, Sweden, July 16, 2019 /PRNewswire/ -- Ra Pharmaceuticals, Inc. (Nasdaq: RARX) and Camurus AB (Nasdaq STO: CAMX) today announced an exclusive worldwide license agreement for the use of Camurus's proprietary FluidCrystal® (FC) technology to develop, manufacture, and commercialize a long-acting formulation of zilucoplan, Ra Pharma's complement component 5 (C5) inhibitor in development for the treatment of multiple complement-mediated disorders.

"Ra is committed to delivering convenient and accessible products for managing C5-mediated diseases. Building on the strength of our daily formulation, which offers a quick, low volume injection and room temperature storage, the FluidCrystal® extended release (XR) formulation of zilucoplan has the potential to control disease for at least seven days from a single subcutaneous dose without the need for intravenous loading, on-body infusion devices, tissue-degrading enzymes, or permeation enhancers. The promising data from our pre-clinical studies conducted with Camurus, the potential for cost-effective manufacturing, and Camurus's proven late-stage regulatory experience with FluidCrystal® were compelling reasons to add the FluidCrystal® technology into our zilucoplan XR life-cycle extension program," said Doug Treco, Ph.D., President and Chief Executive Officer of Ra Pharma.

In pre-clinical testing, a single dose of the FC XR formulation of zilucoplan in non-human primates rapidly achieved and maintained target levels of complement inhibition for at least seven days without the need for an intravenous loading regimen.

"The partnership with Ra Pharma follows the successful completion of a feasibility study of the FluidCrystal® extended release zilucoplan injection, which met formulation, pharmacokinetic, and tolerability target specifications," said Fredrik Tiberg, President & CEO of Camurus. "We look forward to the next phase of our collaboration with Ra Pharma and initiating clinical development of a new promising product candidate based on our unique FluidCrystal® technology."

Under the agreement, Camurus will receive an upfront payment of $2 million and is eligible to receive up to $14.5 million in development milestones and other license payments, up to $55 million in sales milestones, and tiered single digit royalty payments on product sales related to the FC XR formulation of zilucoplan.

About Zilucoplan

Ra Pharma is developing zilucoplan and zilucoplan extended release (XR) for generalized myasthenia gravis (gMG), immune-mediated necrotizing myopathy (IMNM), and other tissue-based, complement-mediated disorders with high unmet medical need. The product candidates are designed for convenient subcutaneous (SC) self-administration. Zilucoplan is an investigational, synthetic, macrocyclic peptide discovered using Ra Pharma's powerful proprietary drug discovery technology. The peptide is designed to bind complement component 5 (C5) with sub-nanomolar affinity and allosterically inhibit its cleavage into C5a and C5b upon activation of the classical, alternative, or lectin pathways.
