Calando Pharmaceuticals Selects Agilent Technologies for siRNA Production.DUARTE, Calif. & PALO ALTO, Calif. -- Calando ca·lan·do adv. & adj. Music With a gradual decrease in volume and often tempo. Used chiefly as a direction. [Italian, present participle of calare, to slacken Pharmaceuticals Inc., a majority-owned subsidiary majority-owned subsidiary A firm in which more than 50% of outstanding voting stock is owned by the parent company. of Arrowhead Research Corporation (NASDAQ NASDAQ in full National Association of Securities Dealers Automated Quotations U.S. market for over-the-counter securities. Established in 1971 by the National Association of Securities Dealers (NASD), NASDAQ is an automated quotation system that reports on :ARWR), has selected Agilent Technologies (NYSE NYSE See: New York Stock Exchange :A) to manufacture the active siRNA component in its lead RNAi product, CALAA01. Calando was formed in 2005 to create, develop and commercialize proprietary technologies for the therapeutic use of RNA interference RNA interference n. A process in which the introduction of double-stranded RNA into a cell inhibits the expression of genes. , or "RNAi." CALAA01 is the first targeted siRNA anti-cancer therapeutic that Calando plans to enter into Phase I clinical trials. Agilent will provide the siRNA component of CALAA01 for Investigational New Drug (IND)- enabling pharmacokinetic and toxicity studies as well as cGMP production for the Phase I clinical study. "Establishing the manufacturing relationship with Agilent for CALAA01 is a major milestone in our development timeline," said Calando CEO (1) (Chief Executive Officer) The highest individual in command of an organization. Typically the president of the company, the CEO reports to the Chairman of the Board. John Petrovich. "We are very impressed with the depth of experience and strong leadership the Agilent team has to offer. In addition, we appreciated the team's ability to offer a complete package of development services, including development of analytical methods, IND supporting studies and stability. These attributes are vitally important in the manufacture of therapeutics as complex as siRNA duplexes." "We're very pleased to be selected by Calando to provide manufacturing and IND-enabling services for their lead RNAi product," said James Powell, general manager of Agilent's Nucleic Acid nucleic acid, any of a group of organic substances found in the chromosomes of living cells and viruses that play a central role in the storage and replication of hereditary information and in the expression of this information through protein synthesis. Solutions Division. "Calando is one of the leading RNAi therapeutics companies, due to their focus on development and commercialization of targeted siRNA therapeutics based on proprietary technologies, and we look forward to working closely with them." Calando Technology Calando's cyclodextrin-containing polymers form the foundation for its two-part siRNA delivery system. The first component is a linear, cyclodextrin-containing polycation that, when mixed with small interfering RNA Small interfering RNA (siRNA), sometimes known as short interfering RNA or silencing RNA, are a class of 20-25 nucleotide-long double-stranded RNA molecules that play a variety of roles in biology. (siRNA), binds to the anionic an·i·on n. A negatively charged ion, especially the ion that migrates to an anode in electrolysis. [From Greek, neuter present participle of anienai, to go up : ana-, ana- "backbone" of the siRNA. The polymer and siRNA self-assemble into nanoparticles of approximately 50 nm diameter that fully protect the siRNA from nuclease nuclease /nu·cle·ase/ (noo´kle-as) any of a group of enzymes that split nucleic acids into nucleotides and other products. nu·cle·ase n. degradation in serum. The siRNA delivery system has been designed for intravenous injection. Upon delivery to the target cell, the targeting ligand binds to membrane receptors on the cell surface and the RNA-containing nanoparticle is taken into the cell by endocytosis endocytosis (ĕn'dōsītō`səs), in biology, process by which substances are taken into the cell. When the cell membrane comes into contact with a suitable food, a portion of the cell cytoplasm surges forward to meet and surround . There, chemistry built into the polymer functions to unpackage the siRNA from the delivery vehicle. In addition to targeting tumors, the targeting of liver cells has also been accomplished in vivo in vivo /in vi·vo/ (ve´vo) [L.] within the living body. in vi·vo adj. Within a living organism. in vivo adv. . Using anti-FAS siRNA, liver targeted delivery from tail vein injections in mice are able to provide FAS gene inhibition like that observed from a high pressure tail vein injection that is not clinically relevant.
