New Drug Approvals 2014 - Pt. VII - Ramucirumab (Cyramza™)

ATC Code:
Wikipedia:Ramucirumab
ChEMBL:CHEMBL1743062

On April 21, 2014 the FDA approved Ramucirumab (Cyramza™) for the treatment of patients with advanced or metastatic, gastric or gastroesophageal junction (GEJ) adenocarcinoma with disease progression on or after prior treatment with fluoropyrimidine- or platinum-containing chemotherapy.

Gastric cancer has a very poor prognosis, with adenocarcinomas constituting ~95% of all gastric cancers (CRUK).

In a randomized, double-blind, multicenter study of ramucirumab plus best supportive care (BSC) compared with placebo plus BSC of 355 patients with locally advanced or metastatic gastric cancer (including adenocarcinoma of the gastro-esophageal junction [GEJ]), ramucirumab improved the overall survival to a median of 5.2 months, compared to 3.8 with the placebo arm. Progression-free survival (PFS) was improved from a median of 1.3 months in the placebo arm to 2.1 months in the ramucirumab arm.

Cyramza has been issued a boxed warning because of increases in the risk of hemorrhage, including severe and sometimes fatal hemorrhagic events.

The target of ramucirumab is the extracellular ligand-binding domain of the receptor tyrosine kinase, Vascular endothelial growth factor receptor 2 (KDR, also known as VEGFR2; Uniprot = P35968 ; ChEMBL = CHEMBL279 ;
canSAR = P35968). Ramucirumab specifically binds to KDR (VEGFR2) thus preventing the binding of its ligands VEGF-A, VEGF-C, and VEGF-D. This blockade inhibits ligand-stimulated activation of VEGF Receptor 2 and consequently, inhibits ligand-induced proliferation and migration of human endothelial cells. Elevated expression of the ligands has been shown to be clinically correlated with survival and with metastasis in gastric cancers.

Ramucirumab is administered intravenously 8 mg/kg every 2 weeks. The mean minimum concentrations (Cmin) were 50 μg/mL (6-228 μg/mL) after the third dose and 74 μg/mL (14-234 μg/mL) after the sixth dose.

Cyramza™ is a product of Eli Lilly & Co.

SureChEMBL gets a facelift

Dear SureChEMBL users, Over the past year, we’ve introduced several updates to the SureChEMBL platform, focusing on improving functionality while maintaining a clean and intuitive design. Even small changes can have a big impact on your experience, and our goal remains the same: to provide high-quality patent annotation with a simple, effective way to find the data you need. What’s Changed? After careful consideration, we’ve redesigned the landing page to make your navigation smoother and more intuitive. From top to bottom: - Announcements Section: Stay up to date with the latest news and updates directly from this blog. Never miss any update! - Enhanced Search Bar: The main search bar is still your go-to for text searches, still with three pre-filter radio buttons to quickly narrow your results without hassle. - Improved Query Assistant: Our query assistant has been redesigned and upgraded to help you craft more precise queries. It now includes five operator options: E...

Improvements in SureChEMBL's chemistry search and adoption of RDKit

Dear SureChEMBL users, If you frequently rely on our "chemistry search" feature, today brings great news! We’ve recently implemented a major update that makes your search experience faster than ever. What's New? Last week, we upgraded our structure search engine by aligning it with the core code base used in ChEMBL . This update allows SureChEMBL to leverage our FPSim2 Python package , returning results in approximately one second. The similarity search relies on 256-bit RDKit -calculated ECFP4 fingerprints, and a single instance requires approximately 1 GB of RAM to run. SureChEMBL’s FPSim2 file is not currently available for download, but we are considering generating it periodicaly and have created it once for you to try in Google Colab ! For substructure searches, we now also use an RDKit -based solution via SubstructLibrary , which returns results several times faster than our previous implementation. Additionally, structure search results are now sorted by...

Here's a nice Christmas gift - ChEMBL 35 is out!

Use your well-deserved Christmas holidays to spend time with your loved ones and explore the new release of ChEMBL 35! This fresh release comes with a wealth of new data sets and some new data sources as well. Examples include a total of 14 datasets deposited by by the ASAP ( AI-driven Structure-enabled Antiviral Platform) project, a new NTD data se t by Aberystwyth University on anti-schistosome activity, nine new chemical probe data sets, and seven new data sets for the Chemogenomic library of the EUbOPEN project. We also inlcuded a few new fields that do impr ove the provenance and FAIRness of the data we host in ChEMBL: 1) A CONTACT field has been added to the DOCs table which should contain a contact profile of someone willing to be contacted about details of the dataset (ideally an ORCID ID; up to 3 contacts can be provided). 2) In an effort to provide more detailed information about the source of a deposited dat...

A python client for accessing ChEMBL web services

Motivation The CheMBL Web Services provide simple reliable programmatic access to the data stored in ChEMBL database. RESTful API approaches are quite easy to master in most languages but still require writing a few lines of code. Additionally, it can be a challenging task to write a nontrivial application using REST without any examples. These factors were the motivation for us to write a small client library for accessing web services from Python. Why Python? We choose this language because Python has become extremely popular (and still growing in use) in scientific applications; there are several Open Source chemical toolkits available in this language, and so the wealth of ChEMBL resources and functionality of those toolkits can be easily combined. Moreover, Python is a very web-friendly language and we wanted to show how easy complex resource acquisition can be expressed in Python. Reinventing the wheel? There are already some libraries providing access to ChEM...
