AL3818 (anlotinib) is a receptor tyrosine kinase inhibitor targeting vascular endothelial growth factor receptors (VEGFR1, VEGFR2/KDR, and VEGFR3), stem cell factor receptor (C-kit), platelet-derived growth factor (PDGFβ), and fibroblast growth factor receptors (FGFR1, FGFR2, and FGFR3). Anlotibib is a kind of innovative medicines approved by State Food and Drug Administration（SFDA:2011L00661) which was researched by Jiangsu Chia-tai Tianqing Pharmaceutical Co., Ltd. Phase III development is underway for the treatment of thyroid cancer, gastric cancer, leiomyosarcoma; non-small cell lung cancer; synovial sarcoma; thyroid cancer etc.

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 Clovis has also withdrawn its Marketing Authorization Application of rociletinib with European regulatory authorities.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.

Icotinib is an orally available quinazoline-based inhibitor of epidermal growth factor receptor. It selectively inhibits the wild-type and several mutated forms of EGFR tyrosine kinase. The major organ of icotinib metabolism is the liver, with the primarily enzymes being CYP2C19 and CYP3A4 from the cytochrome P450 monooxygenase system. Icotinib Hydrochloride was approved for the treatment of patients with advanced stage Nonsmall cell lung cancer by the State Food and Drug Administration (SFDA) of China. The major drug related adverse reactions of the traditional cytotoxic agents include rash, diarrhea, severe bone marrow suppression, neuropathy, hair loss, and gastrointestinal reactions. Icotinib is under investigation as an active agent against other EGFR mutation-positive cancers, like lung adenocarcinoma, oesophageal cancer, nasopharyngeal cancer and others.

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.

Olmutinib is a novel third-generation epidermal growth factor receptor (EGFR) mutation-specific tyrosine kinase inhibitor, used in the treatment of T790M mutation positive non-small cell lung cancer. Olmutinib covalently binds a cysteine residue near the kinase domain of mutant EGFRs to prevent phosphorylation of the receptor. EGFRs are frequently over-expressed in lung cancer and contribute to activation of the phosphoinositide 3-kinase and mitogen-activated protein kinase pathways which both promote cell survival and proliferation. By inhibiting EGFR activation, Olmutinib attenuates the activation of these tumor-promoting pathways. In the first phase I/II clinical study of Osimertinib, 800 mg/ day was chosen as the dose for subsequent studies, and the dose-limiting toxicity and maximum tolerated dose was not reached. Olmutinib received breakthrough therapy designation in the United States in December 2015 and was approved for use in Korea in May 2016.

Amrubicin is a totally synthetic 9-aminoanthracycline anticancer drug, which is approved in Japan for the treatment of small cell and non-small cell lung cancer. Upon administration amrubicin is reduced to its C-13 hydroxy metabolite, amrubicinol. The cytotoxicity of amrubicinol in vitro is 10 to 100 times greater than that of amrubicin. Thus, the anticancer activity of amrubicin is considered to derive from this active metabolite. The mechanism of action of the drug is related to the inhibition of topoisomerase II by stabilizing the cleavable complex.

Suramin is an antiprotozoal and anthelmintic compound. It is indicated for the treatment of African trypanosomiasis (African sleeping sickness; trypanosome fever) and Onchocerciasis (river blindness). Additionally, suramin exhibits antineoplastic action. It was discovered that suramin produced dramatic, but transient, improvement of core symptoms of autism spectrum disorder.

Efaproxiral is a synthetic, small molecule, radiation-sensitising agent being developed by Allos Therapeutics primarily for the treatment of cancer. It works by binding and allosterically stabilising deoxyhaemoglobin in hypoxic regions of tumour tissue. This increases oxygen uptake of the tumour tissue and restores its sensitivity to radiation therapy, making therapy potentially more successful. But no benefit was seen for efaproxiral in phase III clinical trials. The only serious adverse effect detected was hypoxaemia. Efaproxiral is explicitly excluded from the 2012 World Anti-Doping Agency list of Prohibited Substances and is explicitly included in the Prohibited Methods section M1 as a forbidden procedure to alter the oxygen-haemoglobin dissociation curve in order to allosterically modify haemoglobin.
