Gemtuzumab ozogamicin, sold under the brand name Mylotarg®, is an antibody-drug conjugate that is used to treat acute myeloid leukemia (AML).
Cefpodoxime is an oral, third-generation cephalosporin antibiotic available in various generic preparations. It is active against both Gram-positive and Gram-negative organisms with notable exceptions including Pseudomonas aeruginosa, Enterococcus, and Bacteroides fragilis. It is typically used to treat acute otitis media, pharyngitis, sinusitis, and gonorrhea. It also finds use as oral continuation therapy when intravenous cephalosporins are no longer necessary for continued treatment.
Oritavancin, sold under the brand name Orbactiv among others, is a semisynthetic glycopeptide antibiotic medication for the treatment of serious Gram-positive bacterial infections. Its chemical structure as a lipoglycopeptide is similar to vancomycin.
Basilea Pharmaceutica is a biopharmaceutical company based in Allschwil near Basel, Switzerland. Basilea was spun off from F. Hoffmann-La Roche in 2000 and has been listed as an independent company on the Swiss stock exchange since March 2004. The company's subsidiary is Basilea Pharmaceutica International AG, Allschwil, which is also based in Allschwil, Switzerland, and in which the company's operating activities are bundled.
Ceftobiprole, sold under the brand name Zevtera among others, is a fifth-generation cephalosporin antibacterial used for the treatment of hospital-acquired pneumonia and community-acquired pneumonia. It is marketed by Basilea Pharmaceutica under the brand names Zevtera and Mabelio. Like other cephalosporins, ceftobiprole exerts its antibacterial activity by binding to important penicillin-binding proteins and inhibiting their transpeptidase activity which is essential for the synthesis of bacterial cell walls. Ceftobiprole has high affinity for penicillin-binding protein 2a of methicillin-resistant Staphylococcus aureus strains and retains its activity against strains that express divergent mecA gene homologues. Ceftobiprole also binds to penicillin-binding protein 2b in Streptococcus pneumoniae (penicillin-intermediate), to penicillin-binding protein 2x in Streptococcus pneumoniae (penicillin-resistant), and to penicillin-binding protein 5 in Enterococcus faecalis.
Targanta Therapeutics Corporation was a biopharmaceutical company headquartered in Cambridge, Massachusetts. The company also had operations in Indianapolis, Montreal and Toronto. Targanta completed its initial public offering on October 9, 2007 and traded on the Nasdaq market under the symbol: TARG. Targanta was acquired by The Medicines Company in 2009.
Dalbavancin, sold under the brand names Dalvance in the US and Xydalba in the EU among others, is a second-generation lipoglycopeptide antibiotic medication. It belongs to the same class as vancomycin, the most widely used and one of the treatments available to people infected with methicillin-resistant Staphylococcus aureus (MRSA).
Cefovecin (INN) is an antibiotic of the cephalosporin class, licensed for the treatment of skin infections in cats and dogs. It is marketed by Zoetis under the trade name Convenia. It is used to treat skin infections caused by Pasteurella multocida in cats, and Staphylococcus intermedius and Streptococcus canis in dogs. The advantage of using a long-acting injectable antibiotic is that, unlike in daily administration, doses cannot be missed. Missed doses may allow partially resistant microbes to recover. The disadvantage is the presence of subtherapeutic concentrations in the weeks after the resolution of infections. This is associated with the development of resistance in microbes. It should not be used in pregnant or lactating animals or in animals with a history of allergies to penicillin or cephalosporin drugs.
Iclaprim is an antibiotic drug candidate that is active against Gram positive organisms. It is administered intravenously.
Delafloxacin sold under the brand name Baxdela among others, is a fluoroquinolone antibiotic used to treat acute bacterial skin and skin structure infections.
Tedizolid, sold under the brand name Sivextro is an oxazolidinone-class antibiotic. Tedizolid phosphate is a phosphate ester prodrug of the active compound tedizolid. It was developed by Cubist Pharmaceuticals, following acquisition of Trius Therapeutics, and is marketed for the treatment of acute bacterial skin and skin structure infections.
Ceftaroline fosamil (INN), brand name Teflaro in the US and Zinforo in Europe, is a cephalosporin antibiotic with anti-MRSA activity. Ceftaroline fosamil is a prodrug of ceftaroline. It is active against methicillin-resistant Staphylococcus aureus (MRSA) and other Gram-positive bacteria. It retains some activity of later-generation cephalosporins having broad-spectrum activity against Gram-negative bacteria, but its effectiveness is relatively much weaker. It is currently being investigated for community-acquired pneumonia and complicated skin and skin structure infection.
Lipoglycopeptides are a class of antibiotic that have lipophilic side-chains linked to glycopeptides. The class includes oritavancin, telavancin and dalbavancin.
Trius Therapeutics was a biopharma company based in San Diego, CA that focused on the development of antibiotics.
Omadacycline, sold under the brand name Nuzyra, is a broad spectrum antibiotic medication belonging to the aminomethylcycline subclass of tetracycline antibiotics. In the United States, it was approved in October 2018, for the treatment of community-acquired bacterial pneumonia and acute skin and skin structure infections.
Brilacidin, an investigational new drug, is a polymer-based antibiotic currently in human clinical trials, and represents a new class of antibiotics called host defense protein mimetics, or HDP-mimetics, which are non-peptide synthetic small molecules modeled after host defense peptides (HDPs). HDPs, also called antimicrobial peptides, some of which are defensins, are part of the innate immune response and are common to most higher forms of life. As brilacidin is modeled after a defensin, it is also called a defensin mimetic.
Seagen Inc. is an American biotechnology company focused on developing and commercializing innovative, empowered monoclonal antibody-based therapies for the treatment of cancer. The company, headquartered in Bothell, Washington, is the industry leader in antibody-drug conjugates or ADCs, a technology designed to harness the targeting ability of monoclonal antibodies to deliver cell-killing agents directly to cancer cells. Antibody-drug conjugates are intended to spare non-targeted cells and thus reduce many of the toxic effects of traditional chemotherapy, while potentially enhancing antitumor activity.
