NCT03042013: Phase 2 Interventional Withdrawn Subjects With NSCLC With an EGFR Activating Mutation
(2017)

Class (Stereo):
CHEMICAL (ABSOLUTE)



Naquotinib (ASP8273) is an orally available, irreversible, mutant-selective, epidermal growth factor receptor (EGFR) inhibitor, with potential antineoplastic activity. Naquotinib was found by mass spectrometry to covalently bind to a mutant EGFR (L858R/ T790M) via cysteine residue 797 in the kinase domain of EGFR with long-lasting inhibition of EGFR phosphorylation for 24 h. In the NSCLC cell lines harboring the above EGFR mutations, Naquotinib had IC50 values of 8-33 nM toward EGFR mutants, more potently than that of WT EGFR (IC50 value of 230 nM). In mouse xenograft models, Naquotinib induced complete regression of the tumors after 14 days of treatment. ASP8273 even showed activity in mutant EGFR cell line which is resistant to other EGFR TKIs. Naquotinib is in phase III clinical trials for the oral treatment of EGFR mutated non-small cell lung cancer (NSCLC).

Pumosetrag is a novel, orally active and selective 5-HT 3 agonist. It is a partial agonist in rats and guinea-pig and a full agonist in the mouse, suggesting important species differences in 5-HT3 receptor structure. Pumosetrag had been in phase II clinical trials for the treatment of gastroesophageal reflux disease and irritable bowel syndrome. No serious adverse events were reported. Diarrhea was not more common on the drug and only one subject experienced pruritus. All researches on this drug candidate are discontinued.

LY2886721 is a BACE inhibitor used for the treatment of Alzheimer's Disease. LY2886721 did not inhibit other aspartyl proteases such as cathepsin D, pepsin, and renin, and reduced Aβ in a dose-dependent manner in HEK293Swe cells and in primary neurons from PDAPP transgenic mice. LY2886721 was the first BACE inhibitor to reach Phase 2 clinical research. Lilly completed six Phase 1 studies of LY2886721’s safety, tolerability, and pharmacology in a total of 150 healthy volunteers and people with Alzheimer’s disease at doses of 1–70 mg. Single and multiple ascending oral dosing was accompanied by repeat CSF sampling in the hours and days thereafter. This was done to assess CSF penetration and target engagement by way of measuring levels of the drug, BACE1 substrate, and BACE1 cleavage products. The compound lowered CSF Aβ40, Aβ42, and sAPPβ concentrations while increasing sAPPα, consistent with expectations for BACE1 inhibition. Fourteen days of daily dosing reduced BACE1 activity by 50–75 percent, and CSF Aβ42 by 72 percent. No safety concerns were apparent in dosing up to six weeks

BGT 226 is an orally available, small molecule, the dual inhibitor of mammalian target of rapamycin (mTOR) and phosphatidylinositol 3'kinase (PI3K), developed by Novartis for the treatment of solid tumors, including advanced breast cancer. A phase I/II trial was completed in the US, Canada, and Spain, and a phase I trial was completed in Japan. However, development appears to have been discontinued.

Iganidipin is a new dihydropiridynic derivative of calcium antagonist. It is the only currently available calcium antagonist in the form of ophthalmic solution. Its topical administration increases ipsilateral optic nerve head blood flow in rabbits and monkeys and inhibits the contraction of blood vessels induced by endothelin -1. Iganidipin is also used for treat Angina pectoris and Hypertension.

Endoxifen, also known as N-desmethyl-4-hydroxytamoxifen, is active metabolites of tamoxifen. This metabolite exhibits a 100-fold higher binding affinity to the estrogen receptor (ER) and are more effective in suppressing cell proliferation than tamoxifen. In humans, the conversion from tamoxifen to endoxifen is predominant. Endoxifenis is an orally active, selective estrogen receptor modulator (SERM) that was developed for the treatment of estrogen receptor-positive breast cancer. In addition, this drug possesses antimanic properties, what can be used in the treatment of patients with bipolar I disorder (BPD I).

BMS-833923 was discovered by Exelixis and was out-licensed to Bristol-Myers Squibb. BMS-833923 is an orally bioavailable Smoothened antagonist. BMS-833923 reduces hedgehog pathway activity, decreases cell proliferation and induces apoptosis via the intrinsic pathway in esophageal adenocarcinoma (EAC) cell lines. BMS-833923 dose-dependently affects canonical and prostate hedgehog signature gene transcription in vitro. BMS-833923 is in phase II clinical trials for the treatment of chronic myeloid leukaemia.

XK-469 (2-[4-(7-chloro-2-quinoxalinyloxy)phenoxy]-propionic acid) is a novel synthetic quinoxaline phenoxypropionic acid derivative. The R-isomer of XK-469 was approximately twice as effective as the S-isomer of XK-469R. R( )-isomers induce reversible protein DNA crosslinks in mammalian cells. It acts as a selective topoisomerase IIβ inhibitor. A phase I study was performed to determine the safety and pharmacokinetics of XK-469, (R)- in patients with various neoplasms.

Semapimod (CNI-1493) is a cytokine inhibitor and synthetic guanylhydrazone mitogen-activated protein kinase blocker, is being developed by Cytokine PharmaSciences as a potential treatment for Crohn's disease and other inflammatory conditions. As of December 2001, a phase I study demonstrating the safety of the compound had been completed and phase II trials for psoriasis and Crohn's disease were ongoing. In April 2003, preclinical and early clinical studies were underway for a variety of indications, including congestive heart failure and pancreatitis. Semapimod inhibits activation of p38 MAPK and NF-κB and induction of cyclooxygenase-2 by TLR ligands, but not by IL-1β or stresses. Semapimod inhibits TLR4 signaling (IC50 ≈0.3 umol) and acts by desensitizing cells to LPS; it fails to block responses to LPS concentrations of ≥5 ug/ml. Semapimod had been in phase II clinical trials by Ferring Pharmaceuticals for the treatment of Crohn's disease. However, this research has been discontinued. Semapimod is in phase I clinical trials for the treatment of autoimmune disorders and inflammation.
