belzutifan

mrdef: Belzutifan is an inhibitor of hypoxia-inducible factor 2 alpha (HIF-2alpha), with potential antineoplastic activity. HIF-2alpha is a transcription factor that plays a role in oxygen sensing by regulating genes that promote adaptation to hypoxia. Under normal oxygen levels, HIF-2alpha is targeted for ubiquitin-proteasomal degradation by VHL protein. Lack of functional VHL protein results in stabilization and accumulation of HIF-2alpha. Upon stabilization, HIF-2alpha translocates into the nucleus and interacts with hypoxia-inducible factor 1 beta (HIF-1beta) to form a transcriptional complex that induces expression of downstream genes, including genes associated with cellular proliferation, angiogenesis, and tumor growth. Belzutifan binds to HIF-2alpha, and in conditions of hypoxia or impairment of VHL protein function, belzutifan blocks the HIF-2alpha-HIF-1beta interaction, leading to reduced transcription and expression of HIF-2alpha target genes. In vivo, belzutifan demonstrated anti-tumor activity in mouse xenograft models of renal cell carcinoma.

anifrolumab

mrdef: Anifrolumab-fnia is a human IgG1kappa monoclonal antibody that binds to subunit 1 of the type I interferon receptor (IFNAR) with high specificity and affinity. This binding inhibits type I IFN signaling, thereby blocking the biologic activity of type I IFNs. Anifrolumab-fnia also induces the internalization of IFNAR1, thereby reducing the levels of cell surface IFNAR1 available for receptor assembly. Blockade of receptor mediated type I IFN signaling inhibits IFN responsive gene expression as well as downstream inflammatory and immunological processes. Inhibition of type I IFN blocks plasma cell differentiation and normalizes peripheral T-cell subsets. Type I IFNs play a role in the pathogenesis of SLE. Approximately 60-80% of adult patients with active SLE express elevated levels of type I IFN inducible genes.


avalglucosidase alfa

mrdef: Avalglucosidase alfa-ngpt provides an exogenous source of GAA. The M6P on avalglucosidase alfa-ngpt mediates binding to M6P receptors on the cell surface with high affinity. After binding, it is internalized and transported into lysosomes where it undergoes proteolytic cleavage that results in increased GAA enzymatic activity. Avalglucosidase alfa-ngpt then exerts enzymatic activity in cleaving glycogen.


name: glycogen storage disease due to acid maltase deficiency, late-onset

TF is the primary initiator of the extrinsic blood coagulation cascade. The small molecule, MMAE, is a microtubule-disrupting agent, attached to the antibody via a protease-cleavable linker. Nonclinical data suggests that the anticancer activity of tisotumab vedotin-tftv is due to the binding of the ADC to TF expressing cancer cells, followed by internalization of the ADC-TF complex, and release of MMAE via proteolytic cleavage. MMAE disrupts the microtubule network of actively dividing cells, leading to cell cycle arrest and apoptotic cell death. In vitro, tisotumab vedotin-tftv also mediates antibody-dependent cellular phagocytosis and antibody-dependent cellular cytotoxicity.


bimekizumab

mrdef: Bimekizumab is a humanised IgG1/kappa monoclonal antibody that selectively binds with high affinity to IL-17A, IL-17F and IL-17AF cytokines, blocking their interaction with the IL-17RA/IL-17RC receptor complex. Elevated concentrations of IL-17A and IL-17F have been implicated in the pathogenesis of several immune-mediated inflammatory diseases including plaque psoriasis. Bimekizumab inhibits these proinflammatory cytokines, resulting in the normalization of skin inflammation and as a consequence improvement in clinical symptoms associated with psoriasis. From in vitro models, bimekizumab was shown to inhibit psoriasis-related gene expression and cytokine production to a greater extent than inhibition of IL-17A alone.

tralokinumab

mrdef: Tralokinumab is a fully human IgG4 monoclonal antibody that specifically binds to the type 2 cytokine interleukin-13 (IL-13) and inhibits its interaction with the IL-13 receptors. Tralokinumab neutralises the biological activity of IL-13 by blocking its interaction with the IL-13Ralpha1/IL-4Ralpha receptor complex. IL-13 is a major driver of human type 2 inflammatory disease, such as atopic dermatitis and inhibiting the IL-13 pathway with tralokinumab in patients decreases many of the mediators of type 2 inflammation.


vosoritide

mrdef: Vosoritide is a modified type C natriuretic peptide (CNP). In patients with achondroplasia, endochondral bone growth is negatively regulated due to a gain of function mutation in fibroblast growth factor receptor 3 (FGFR3). Binding of vosoritide to natriuretic peptide receptor-B (NPR-B) antagonises FGFR3 downstream signalling by inhibiting the extracellular signal-regulated kinases 1 and 2 (ERK1/2) in the mitogen-activated protein kinase (MAPK) pathway at the level of rapidly accelerating fibrosarcoma serine/threonine protein kinase (RAF-1). As a result, vosoritide, like CNP, acts as a positive regulator of endochondral bone growth as it promotes chondrocyte proliferation and differentiation.

ioflupane

mrdef: Ioflupane binds reversibly to the human recombinant dopamine transporter (DaT). Following administration of DaTscan to humans, radioactive decay of the iodine 123 emits gamma radiation which can be detected externally using gamma detectors, allowing visualization of the brain striata through SPECT imaging. Autoradiography of post-mortem human brain slices exposed to radiolabeled ioflupane shows concentration of the radiolabel in striatum (caudate nucleus and putamen). The specificity of the binding of ioflupane I 125 to dopamine transporter was demonstrated by competition studies with the DaT inhibitor GBR 12909 (a dopamine reuptake inhibitor), the serotonin reuptake inhibitor citalopram, and the norepinephrine reuptake inhibitor desipramine in post-mortem human brain slices exposed to radiolabeled ioflupane.  Citalopram reduced binding in the neocortex and thalamus with only minor effects in the striatum. This indicated that the binding in the cortex and thalamus is mainly to the serotonin reuptake sites.  Desipramine showed no effect on the level of striatal binding of ioflupane I 125, but reduced extrastriatal binding by 60 to 85%.  The binding of ioflupane I 125 to the striatum was abolished in the presence of high concentrations of GBR 12909, indicating selectivity of ioflupane binding for the pre-synaptic DaT.

pabinafusp alfa

mrdef: Pabinafusp alfa is a fusion protein consisting of a humanized anti-hTfR antibody and hIDS. The humanized anti-hTfR antibody is considered to bind to TfRs expressed in the luminal cell membrane of brain microvascular endothelial cells composing the blood-brain barrier, being transported together with the TfR, passing through brain microvascular endothelial cells via transcytosis (which involves the mechanisms of uptake into the cell via endocytosis and release outside the cell via exocytosis) and further penetrating the basal lamina into neuronal cells in the brain parenchyma. In addition, after binding of pabinafusp alfa to M6PR on the cell membrane and cellular uptake via endocytosis, newly formed endosomes are thought to fuse with lysosomes and move into them. In patients with MPS, the type of accumulating GAG differs depending on the MPS phenotype, and CNS symptoms develops in patients with MPS phenotypes that are associated with the accumulation of HS. HS concentrations in CSF are high in patients with MPS-II who have intellectual disability, compared with those who do not have intellectual disability. These findings and other factors have suggested that HS plays a vital role in the development of CNS symptoms. The hIDS of pabinafusp alfa is considered to promote the degradation of HS in the brain parenchyma, thereby suppressing the development or progression of CNS symptoms. It has been demonstrated that pabinafusp alfa has binding affinity for M6PR and hTfR, and is taken up by human fibroblasts via the receptors.

mrdef: Mirogabalin, a novel ligand for the alpha2delta subunit of voltage-gated calcium channels, has been approved for the treatment of peripheral neuropathic pain including painful diabetic peripheral neuropathy (DPNP) and postherpetic neuralgia (PHN) in Japan. Mirogabalin showed potent and selective binding affinities for the alpha2delta subunits, and slower dissociation rates for the alpha2delta-1 subunit than for the alpha2delta-2 subunit. It also showed potent and long-lasting analgesic effects in rat models of neuropathic pain, and wider safety margins for the central nervous system side effects. A pharmacological study using mutant mice demonstrated that the analgesic effects of mirogabalin were mediated by binding of the drug to the alpha2delta-1 subunit, not the alpha2delta-2 subunit.
