Roxadustat (FG-4592) is an HIF α prolyl hydroxylase inhibitor in a cell-free assay. It stabilizes HIF-2 and induces EPO production and stimulates erythropoiesis. Roxadustat transiently and moderately increased endogenous erythropoietin and reduced hepcidin. It is currently being investigated as an oral treatment for anemia associated with chronic kidney disease (CKD). In April 2006, Roxadustat (FG-4592) was licensed to Astellas Pharma by originator FibroGen in Asia, Europe and South Africa for the treatment of anemia. FibroGen retains rights in the rest of the world. In 2007, the FDA put the trial on clinical hold due to one case of death by fulminant hepatitis during a phase II clinical trial for patients with anemia associated with chronic kidney disease and not requiring dialysis. However, in 2008, the FDA informed the company that clinical trials could be resumed. Phase II/III clinical trials for this indication resumed in 2012. In 2013, the compound was licensed to AstraZeneca by FibroGen for development and marketing in US, CN and all major markets excluding JP, Europe, the Commonwealth of Independent States, the Middle East and South Africa, for the treatment of anemia associated with chronic kidney disease (CKD) and end-stage renal disease (ESRD).

Potassium canrenoate (INN, JAN) or canrenoate potassium (USAN) (brand names Venactone, Soldactone), the potassium salt of canrenoic acid, is an aldosterone antagonist of the spirolactone group. Like spironolactone, it is a prodrug, which is metabolized to canrenone in the body. Potassium canrenoate is not licensed in the UK, but may sometimes be prescribed off-licence to treat oedema. It is given intravenously. Potassium canrenoate is a mineralocorticoid receptor (MR) antagonist. The blockade with MR antagonist have beneficial effects in patients with heart failure and myocardial infarction, often attributed to blocking aldosterone action in the myocardium.

N,N-Dimethylcarbamoylmethyl alpha,2-dimethyl-5H-[1]- benzopyrano[2,3-b]pyridine-7-acetate (Y-23023/ Tilnoprofen arbamel) is a prodrug developed as a new non-steroidal anti-inflammatory drug (NSAID), by Yoshitomi and Japan Tobacco for treatment pain in Rheumatoid arthritis, but was discontinued. Y-23023 is rapidly hydrolysed to an active metabolite, alpha,2-dimethyl-5H-[1]benzopyrano[2,3-b]pyridine-7-acetic acid (TILNOPROFENIC ACID), cyclo-oxygenase inhibitor.

Rociletinib is a novel, potent, small molecule, third generation TKI that irreversibly binds and inhibits EGFR with the common activating (L858R, Del19) and T790M resistance mutations. The proposed indication of rociletinib is for the treatment of patients with mutant EGFR NSCLC who have been previously treated with an EGFR-targeted therapy and have the T790M mutation as detected by an FDA approved test. The results from two Phase 2 studies show that rociletinib 625 mg BID treatment has a favorable benefit:risk profile in patients with recurrent T790M-positive mutant EGFR NSCLC based on clinically meaningful and durable responses and a well-established and acceptable safety profile in this patient population with terminal lung cancer. In May 2016, Clovis Oncology, Inc. announced it has terminated enrollment in all ongoing sponsored studies of rociletinib, including TIGER-3, after the company was notified at meeting with the FDA that it could anticipate receiving a Complete Response Letter (CRL) for the rociletinib NDA on or before the PDUFA date of June 28, 2016. Clovis has also withdrawn its Marketing Authorization Application of rociletinib with European regulatory authorities.

Tetrandrine, isolated from the root of Stephania tetrandra S Moore, is a traditional Chinese clinical agent for silicosis, autoimmune disorders, inflammatory pulmonary diseases, cardiovascular diseases and hypertension. Tetrandrine is a potent MDR-reversing agent and is an ABCB1/ABCC1 inhibitor. Tetrandrine (CBT-1) is being developed by CBA Pharma, as an adjunctive therapy to chemotherapy in various cancer types with multiple drug resistance (MDR), including acute myelogenous leukemia , Breast, Non-Hodgkin’s Lymphoma, Hodgkin’s disease, Non-Small Cell Lung Cancer, Multiple Myeloma, Gallbladder, Pancreatic, Gastrointestinal Tract, Small Cell Lung Cancer, Bladder, Head & Neck, and Sarcoma.

PR-69 (Doranidazole) is a hypoxic radiosensitizer, and is a derivative of 2-nitroimidazole intended to reduce neurotoxicity due to its blood brain barrier (BBB) impermeability. Several studies have shown that doranidazole has a radiosensitizing effect under hypoxia, both in vitro and in vivo. Based on these studies, a phase III trial of doranidazole against advanced pancreatic cancer was performed; it was demonstrated that treatment with doranidazole following radiation significantly improved the tumor mass reduction rate and extended patient survival. Various results have suggested that doranidazole has promising potential for hypoxia-targeting chemoradiotherapy.

Lasofoxifene is an active component of Fablyn. Fablyn is used for the treatment of osteoporosis in postmenopausal women. Lasofoxifene is a nonsteroidal selective estrogen receptor modulator. Lasofoxifene has no effect on CYP2E1- or CYP2D6-mediated drug metabolism and should not affect drugs metabolized by other cytochrome P450 isoenzymes. Common adverse reactions considered to be related to Fablyn therapy were muscle spasms, hot flush and vaginal discharge. Lasofoxifene approved in the EU in 2009 is now withdrawn from use in the European Union.

AFALANINE was developed by Medea Research in Italy and licensed to Pulitzer. Phase III clinical trials of MR 708 were completed by Pulitzer. Antidepressant; Antiparkinsonian; Neuroprotectant; Nootropic, Dopamine receptor agonist, was used to treat Major depressive disorder.

Watanidipine (AE0047) had been NDA filed for the treatment of hypertension in Japan. Watanidipine (as Calbren®) was awaiting registration with Mitsubishi Pharma Corporation in Japan. However, Mitsubishi Pharma Corporation has discontinued the development of this drug. Watanidipine had also been in phase II clinical trials for the treatment of stroke and preclinical trials for atherosclerosis. However, no recent development has been reported. Watanidipine (AE0047) has being shown to be a calcium antagonist with protective effects against cerebral ischaemia and the occurrence of stroke in several animal models.

DAU 6215 (Itasetron) is a selective 5-hydroxytryptamine3 (5-HT3) antagonist, which was developed by Boehringer Ingelheim. And was investigated for treatment the nausea and vomiting induced by chemotherapy, it was confirmed that this drug possessed antiemetic properties. Also was discovered, that chronic treatment with itasetron significantly improved retention abilities of the aged rats in this memory test. However, development of itasetron was terminated.
