FDA approved an NDA for Avycaz ceftazidime/avibactam from Actavis plc (NYSE:ACT) to treat complicated urinary tract infections (cUTIs) and in combination with metronidazole to treat complicated intra-abdominal infections (cIAIs), both of which are caused by Gram-negative pathogens. FDA said the drug should be limited to patients who have few or no alternative treatment options. Actavis plans to launch Avycaz in the second quarter.
The product is a combination of the third-generation cephalosporin ceftazidime and avibactam, which is a broad-spectrum beta lactamase (LACTB) inhibitor. Avycaz has Qualified Infectious Disease Product (QIDP) designation and was under Priority Review.
FDA based its approval in part on existing data for ceftazidime, an approved drug, and in vitro data and animal models in which avibactam was tested. The agency said Avycaz was also studied in two Phase II trials that were "not designed with any formal hypotheses for inferential testing against the active comparators."
Actavis and AstraZeneca plc (LSE:AZN; NYSE:AZN) are jointly developing Avycaz. Actavis has rights to commercialize it in North America; AZ has rights elsewhere. Actavis obtained the drug via its 2014 acquisition of Forest Laboratories Inc.
FDA's Arthritis Advisory Committee postponed a meeting that had been scheduled for March 17 to discuss a BLA from Celltrion Inc. (KOSDAQ:068270) for CT-P13, a biosimilar of Remicade infliximab from Johnson & Johnson (NYSE:JNJ) and Merck & Co. Inc. (NYSE:MRK). FDA said the postponement was "due to information requests pending" with Celltrion. The agency did not announce a new date.
Celltrion said its application for CT-P13 is the first for a biosimilar mAb in the U.S. FDA will ask the committee to discuss use of the humanized mAb against tumor necrosis factor (TNF) alpha to treat rheumatoid arthritis (RA), Crohn's disease, ulcerative colitis, ankylosing spondylitis, psoriatic arthritis and plaque psoriasis (see BioCentury Extra, Feb. 9).
Last September, Celltrion and Hospira Inc. (NYSE:HSP) amended their 2009 partnership, giving Hospira exclusive rights to market the biosimilar in the U.S., Canada and other undisclosed territories (see BioCentury Extra, Feb. 23, 2014).
In Europe, the companies have a co-exclusive agreement which allows Hospira and Celltrion each to market the biosimilar under their own brands. The European Commission approved CT-P13 in September 2013. This month, Hospira launched its biosimilar as Inflectra in 10 new European markets; Inflectra is now available in 24 European countries. On Tuesday, Celltrion launched its biosimilar as Remsima in 12 European countries (see BioCentury Extra, Feb. 24).
Pfizer Inc. (NYSE:PFE) said it will cut an undisclosed number of R&D jobs at its Cambridge, Mass., and Collegeville, Pa., facilities. Pfizer spokesperson Dean Mastrojohn declined to say which R&D areas would be cut. The company plans to reallocate resources to areas including immuno-oncology and gene therapy.
In December 2014, Pfizer created a gene therapy unit within its rare disease research area and announced a deal with Spark Therapeutics Inc. (NASDAQ:ONCE) to develop gene therapies to treat hemophilia B (see BioCentury Extra, Dec. 8, 2014).
Last summer, the pharma partnered with immuno-oncology company Cellectis S.A. (Euronext:ALCLS) to develop allogeneic chimeric antigen receptor (CAR) T cell therapies (see BioCentury, July 14, 2014).
Germany's Federal Joint Committee (G-BA) concluded that Sylvant siltuximab from Johnson & Johnson (NYSE:JNJ) provides added benefit for patients with multicentric Castleman's disease (MCD) who are HIV-negative and human herpes virus 8 (HHV-8)-negative, the drug's approved indication.
The committee said the extent of the drug's benefit could not be quantified. G-BA estimated that 130-1,460 patients could benefit from the chimeric mAb against IL-6.
Sylvant has Orphan Drug status in the EU and the U.S. to treat MCD, a B cell proliferative disorder that affects groups of lymph nodes in different anatomical areas. Castleman's disease is not malignant but is chronically debilitating, and can be fatal because of systemic inflammation.
The European Commission approved Sylvant in June 2014; FDA approved it in April 2014 (see BioCentury Extra, June 4, 2014).

Sens. Tom Carper (D-Del.) and Pat Toomey (R-Pa.) reintroduced a bill that would increase and make permanent the alternative simplified R&D tax credit. The bill would increase the tax credit to 25% from the 14% credit that expired last year and enable CROs to claim a portion of the credit. Carper introduced a similar bill last July (see BioCentury Extra, July 31, 2014).
The bill is known as the Competitiveness and Opportunity by Modernizing and Permanently Extending the Tax Credit for Experimentation, or COMPETE Act.
