In vitro studies have demonstrated that Zydelig results in decreased phosphorylation Akt and other downstream effectors, an increase in poly (ADP-ribose) polymerase and caspase cleavage, and an induction of apoptosis.
Zybrestat (fosbretabulin tromethamine; Mateon Therapeutics) is a water-soluble prodrug of cis-combretastatin A4, originally isolated from the African bush willow (Combretum caffrum).
Zulresso is SAGE Therapeutics’ proprietary intravenous formulation of brexanolone, which is an allosteric modulator of both synaptic and extra-synaptic GABA-A receptors.
Zontivity was approved (May 8, 2014) for use with clopidogrel/aspirin, its label was relatively benign, not reporting bleeding in the overall trial, which included stroke/TIA patients who had excessive bleeding with the drug, or in ACS trial, where there was also excessive bleeding.
Zontivity (vorapaxar; Merck & Co) gained US and EU approval for the reduction of thromboembolic
events in secondary-prevention patients with a history of myocardial infarction (MI).
Zoladex (goserelin; AstraZeneca/TerSera Therapeutics) is a gonadotropin-releasing hormone (GnRH) receptor agonist which acts on the pituitary gland to stimulate luteinizing hormone (LH) release, resulting in a temporary surge in serum testosterone levels known as “flare.”
Zinbryta is a humanized monoclonal antibody that selectively binds to the alpha chain (cluster of differentiation [CD]25) of the interleukin-2 receptor on activated T cells to prevent the immunoactivation of MS.
Zevalin (ibritumomab tiuxetan; Acrotech Biopharma/Mundipharma) is an intravenous radioactive agent consisting of the murine monoclonal antibody (MAb) ibritumomab, which is covalently linked to the chelator tiuxetan.
Multiple combination products based on the same active compound are known as a drug franchise. Franchises exist to give physicians, as well as patients, different treatment choices and to help with issues such as pill burden and compliance.
Zepsyre (lurbinectedin; PharmaMar/Chugai) is a novel synthetic agent derived from the marine-derived alkaloid trabectedin that inhibits the transcription process.
Zepatier is a once-daily, fixed-dose combination of Merck & Co’s second-generation protease inhibitor, grazoprevir, and the company’s NS5A inhibitor, elbasvir.
Zeltherva’s (galinpepimut-S; SELLAS Life Sciences Group) larger target patient population gives it more commercial potential than other drugs being positioned towards the maintenance setting.
Zelboraf (vemurafenib; Roche/Chugai/Daiichi Sankyo) is an orally available agent that selectively targets the BRAF mutation. BRAF is part of the mitogen-activated protein kinase (MAPK) signal transduction pathway, which is critical in tumor cell proliferation.
Zelapar (selegiline; Valeant) is a novel rapidly disintegrating tablet formulation of the monoamine oxidase B (MAO-B) inhibitor selegiline.
Zejula (niraprib; Tesaro/Takeda) is a small molecule inhibitor of poly (ADP-ribose) polymerase (PARP). PARP inhibitors block the activity of PARP, an enzyme that plays an essential role in DNA repair mechanisms and homologous recombination events by directly blocking enzymatic activity, or by causing PARP to accumulate on DNA (PARP trapping), which results in DNA replication inhibition and cell death.
Zeftera (ceftobiprole medocaril; Basilea Pharmaceutica) is a novel intravenous broad-spectrum fifth-generation cephalosporin.
Zanubrutinib (BeiGene) is an oral small molecule inhibitor of Bruton’s tyrosine kinase (BTK), developed to be more selective with less off-target effects than Imbruvica (ibrutinib; AbbVie/Johnson & Johnson). BTK is part of the B-cell receptor signaling pathway, which promotes cell proliferation, adhesion, and survival in many B-cell malignancies.
Zaltrap is a human recombinant fusion protein comprising segments of the human VEGFRs 1 and 2 and the Fc portion of the human immunoglobulin G1 (Tang et al., 2008).
Zafatek (trelagliptin; Takeda) is a member of the dipeptidyl peptidase-IV (DPP-IV) inhibitor class.
Yonsa (Churchill Pharmaceuticals) is an oral, ultramicrosize tablet formulation of abiraterone acetate that inhibits 17 alpha-hydroxylase (CYP17). The CYP17 family of enzymes catalyze the hydroxylation of intermediates involved in testosterone synthesis, a common driver of prostate cancer genesis and recurrence.
Ygalo (melphalan-flufenamide; Oncopeptides) is a cytotoxic alkylating agent that consists of melphalan conjugated to phenylalanine
Yescarta (axicabtagene ciloleucel; Gilead) became the first chimeric antigen receptor T-cell (CAR-T) therapy to launch for the treatment of diffuse large B-cell lymphoma (DLBCL) when it gained US approval for relapsed/refractory patients in October 2017.
Yervoy (ipilimumab; Bristol-Myers Squibb/Ono Pharmaceutical) is an intravenous fully humanized immunoglobulin-G1 monoclonal antibody that targets human cytotoxic T-lymphocyte-associated protein-4 (CTLA-4).
Xyntha is a recombinant factor VIII (rfVIII) therapy approved for the treatment of hemophilia A.
Although Pfizer has taken steps to enhance the product by improving the manufacturing processes
and developing an application device for the therapy, Xyntha’s target patient population will be
reduced by competitor therapies approved for prophylactic use.
Xultophy ([insulin degludec + liraglutide]; Novo Nordisk) is a once-daily, injectable combination product comprising a fixed ratio of Novo Nordisk’s long-lasting basal insulin Tresiba (insulin degludec) and glucagon-like peptide-1 receptor agonist Victoza (liraglutide) for the treatment of type 2 diabetes.
Xtandi (enzalutamide; Pfizer/Astellas) is an androgen receptor (AR) signaling inhibitor that inhibits the AR at three distinct points in the signaling pathway. Xtandi competitively inhibits binding of the androgens to the AR, inhibits AR nuclear translocation, and inhibits association of the AR with DNA.
