The agreement between gout player Horizon plc and RNAi expert Arrowhead Pharmaceuticals Inc. could result in a subcutaneously given, infrequently dosed fix for the disease that takes aim at xanthine dehydrogenase. “They brought us the target – it wasn’t something we were developing,” said Arrowhead CEO Christopher Anzalone, but the Pasadena, Calif.-based firm’s research on hepatocyte-directed therapies provides confidence.
Morphosys AG is to acquire Constellation Pharmaceuticals Inc., financed by gambling a huge chunk of its income on the U.S. firm’s BET inhibitor pipeline drug – an approach that has to date produced mixed results in cancer.
With 10 cases of serious shock and anaphylaxis, including one death, in the month since Seikagaku Corp.’s osteoarthritis drug, Joyclu (diclofenac etalhyaluronate sodium), launched in Japan, the Pharmaceuticals and Medical Devices Agency (PMDA) issued a blue letter to health care professionals and is adding a warning section to the drug’s Japanese label.
The FDA’s Arthritis Advisory Committee panelists groped through cloudy data while complaining about the design of the phase III trial for Chemocentryx Inc.’s avacopan, and after going overtime ended up without consensus. Briefing documents ahead of the meeting darkened what had been a fairly bright picture for the complement C5a receptor inhibitor for anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis, but Wall Street held out hope. Wainwright analyst Edward White opined in a May 5 report that the adcom’s outcome “could still be positive,” and a May 4 dispatch from Canaccord Genuity’s Michelle Gilson said the briefing docs “miss[ed] the big picture.”
Stock-price weakness that has beset Chemocentryx Inc. since early March – likely based on jitters ahead of the FDA advisory panel for avacopan slated for May 6 – became an outright tumble when Wall Street got a gander at briefing documents related to the meeting. Shares of the San Carlos, Calif-based firm (NASDAQ:CCXI) closed at $22.19, down $26.63, or 45%, as company backers sifted paperwork on the complement C5a receptor inhibitor for anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis. The compound has been assigned a PDUFA date of July 7.
LONDON – C4X Discovery Holdings plc has out-licensed its preclinical oral interleukin-17 (IL-17) inhibitor to Sanofi SA in a potential €414 million (US$493.4 million) deal. Under the terms of the agreement, Sanofi is paying €7 million up front and a further €11 in short-term preclinical milestones, with the balance to follow on reaching development, regulatory and commercialization milestones.
HONG KONG – Seikagaku Corp. and Ono Pharmaceutical Co. Ltd. have cleared the final hurdle for Joyclu (diclofenac etalhyaluronate sodium), with Japan’s Ministry of Health, Labour and Welfare granting manufacturing and marketing approval for the osteoarthritis (OA) therapy, the first agent to be approved in Japan for improving hip joint function in OA. The intra-articular injection was also approved for the treatment of knee joint OA.
Marking its second acquisition this year after snapping up cancer-focused Five Prime Therapeutics Inc., Amgen Inc. is adding to its inflammatory disease portfolio through the purchase of Seattle-based Rodeo Therapeutics Corp. The deal includes $55 million up front for the private company's shareholders, plus contingent milestone payments worth up to an additional $666 million. Rodeo's lead preclinical program targets 15-prostaglandin dehydrogenase to increase tissue levels of prostaglandin PGE2.
If the March 25 vote from a joint FDA advisory committee meeting is anything to go by, the long and bumpy development road for Pfizer Inc.’s tanezumab, a nonopioid pain drug, may have just gotten longer and bumpier. In what was nearly a unanimous vote, the Arthritis Advisory Committee and Drug Safety and Risk Management Advisory Committee said the sponsor’s proposed risk evaluation and mitigation strategy (REMS) was not adequate to ensure the benefits of tanezumab in alleviating osteoarthritis pain outweigh its risks, which include further joint deterioration.
With the December PDUFA date already blown, Pfizer Inc. is headed into a day-and-a-half FDA advisory committee meeting this week to make the case for 2.5-mg tanezumab, a potential first-in-class treatment in the U.S., partnered with Eli Lilly and Co. Inc., for chronic pain due to moderate to severe osteoarthritis.
