Alipogene tiparvovec (Glybera®; AMT-011, AAV1-LPLS447X) is an adeno-associated virus serotype 1-based gene therapy for adult patients with familial lipoprotein lipase (LPL) deficiency (LPLD) and suffering from severe or multiple pancreatitis attacks despite dietary fat restrictions. It is administered as a one-time series of intramuscular injections in the legs. LPLD, a rare autosomal recessive disorder, results in hyperchylomicronaemia and severe hypertriglyceridaemia, which in turn, are associated with an increased risk of clinical complications, the most debilitating of which is recurrent severe and potentially life-threatening pancreatitis. In clinical studies (n = 27 patients), one-time administration of alipogene tiparvovec was associated with significant reductions in plasma triglyceride levels during the 12 or 14 week study period post administration. Although triglyceride levels returned to pre-treatment levels within 16-26 weeks after administration, patients had sustained improvements in postprandial chylomicron metabolism, with sustained expression of functional copies of the LPLS477X gene and of biologically active LPL in skeletal muscle. Moreover, after up to 6 years' follow-up post administration, there were clinically relevant reductions in the incidence of documented pancreatitis and acute abdominal pain events consistent with pancreatitis. Alipogene tiparvovec was generally well tolerated, with most adverse events being localized, transient, mild to moderate injection-site reactions. This article reviews the pharmacology of alipogene tiparvovec and its efficacy and safety in adults with LPLD. © 2014 Springer International Publishing Switzerland. Source

Belinostat [Beleodaq® (US)], a small-molecule hydroxamate-type inhibitor of class I, II and IV histone deacetylase (HDAC) enzymes, has been developed by TopoTarget and Spectrum Pharmaceuticals for the treatment of relapsed or refractory peripheral T-cell lymphoma (PTCL). Belinostat has received its first global approval as monotherapy for this indication in the US, under the Food and Drug Administration's accelerated approval program. This article summarizes the milestones in the development of belinostat leading to this first approval for the treatment of PTCL. © 2014 Springer International Publishing Switzerland. Source

Pembrolizumab [Keytruda® (US)], a humanized monoclonal antibody against the programmed death receptor-1 (PD-1) protein, has been developed by Merck & Co for the treatment of cancer. Pembrolizumab has received its first global approval for the treatment of advanced, unresectable or metastatic malignant melanoma in the US, for use in patients with disease progression after prior treatment with ipilimumab and, for BRAF V600 mutation-positive patients, a BRAF inhibitor. It is the first anti-PD-1 therapy to receive regulatory approval in the US, and is currently under regulatory review in the EU. This article summarizes the milestones in the development of pembrolizumab leading to this first approval for the treatment of malignant melanoma. © 2014 Springer International Publishing Switzerland.

Ripasudil hydrochloride hydrate (Glanatec® ophthalmic solution 0.4 %; hereafter referred to as ripasudil) is a small-molecule, Rho-associated kinase inhibitor developed by Kowa Company, Ltd. for the treatment of glaucoma and ocular hypertension. This compound, which was originally discovered by D. Western Therapeutics Institute, Inc., reduces intraocular pressure (IOP) by directly acting on the trabecular meshwork, thereby increasing conventional outflow through the Schlemm's canal. As a result of this mechanism of action, ripasudil may offer additive effects in the treatment of glaucoma and ocular hypertension when used in combination with agents such as prostaglandin analogues (which increase uveoscleral outflow) and β blockers (which reduce aqueous production). The eye drop product has been approved in Japan for the twice-daily treatment of glaucoma and ocular hypertension, when other therapeutic agents are not effective or cannot be administered. Phase II study is underway for the treatment of diabetic retinopathy. This article summarises the milestones in the development of ripasudil leading to the first approval for glaucoma and ocular hypertension. © 2014 Springer International Publishing Switzerland.

Olaparib (Lynparza™) is an oral, small molecule, poly (ADP-ribose) polymerase inhibitor being developed by AstraZeneca for the treatment of solid tumours. The primary indication that olaparib is being developed for is BRCA mutation-positive ovarian cancer. A capsule formulation of the drug has received approval for use in this setting in the EU and USA, and a tablet formulation is in global phase III trials (including in the USA, EU, Australia, Brazil, Canada, China, Israel, Japan, Russia and South Korea). In addition, phase III trials in breast, gastric and pancreatic cancer are underway/planned, and phase I/II investigation is being conducted in other malignancies, including prostate cancer, non-small cell lung cancer, Ewing's sarcoma and advanced cancer. This article summarizes the milestones in the development of olaparib leading to this first approval for ovarian cancer. © 2015 Springer International Publishing Switzerland. Source
