Curis phase 1 Cancer Trial for CUDC-427 Begins


CUDC-427, GDC-0917; RG-7459

Genentech Inc (Roche Holding AG)

Curis licenses GDC-0917 from Genentech

Curis Cancer Trial Begins
Curis Inc. has initiated patient dosing in a second Phase 1 dose-escalation study of CUDC-427 that is being conducted using a continuous, twice-daily oral dosing regimen in patients with advanced and refractory solid tumors or lymphoma.

FULL STORY

http://www.dddmag.com/news/2013/07/curis-cancer-trial-begins?et_cid=3387991&et_rid=523035093&type=headline

About CUDC-427 (GDC-0917)

CUDC-427 is an orally bioavailable small molecule that is designed to promote cancer cell death by antagonizing IAP proteins.  IAP proteins are a family of functionally and structurally related proteins that promote cancer cell survival by inhibiting programmed cell death, also known as apoptosis, which is a normal process inherent in every cell.  Using IAP proteins and other anti-apoptotic factors, cancer cells evade apoptosis in response to a variety of signals, including those provided by anti-cancer agents such as chemotherapy, or naturally occurring inflammatory and immune signals transmitted through members of the tumor necrosis factor, or TNF, family of factors.  Evasion from apoptosis is a fundamental mechanism whereby human cancers develop resistance to standard anti-cancer treatments.  IAP inhibitors such as CUDC-427 are designed to counteract the effects of IAP proteins, thus shifting the balance away from cancer cell survival and allowing apoptosis to proceed.

CUDC-427 was designed to mimic the endogenous IAP antagonist mitochondrial protein second mitochondria-derived activator of caspases/direct IAP-binding protein (Smac/DIABLO) that is released into the cytoplasm in response to pro-apoptotic stimuli.  CUDC-427 has demonstrated single-agent and combination anti-tumor activity in mouse xenograft tumor models when administered orally on a daily schedule, and IND-enabling safety studies have shown it to be well tolerated when dosed daily by oral administration, potentially enabling sustained target inhibition.

In October 2010, an open-labeled, uncontrolled, dose-escalation, Phase I clinical trial of CUDC-427 (NCT01226277; IAM4914g) began in patients with refractory solid tumors or lymphoma. Genentech recently completed this Phase I clinical trial in which 42 people received daily oral doses of CUDC-427 for two weeks, followed by a one week rest period.  This 21-day cycle is repeated until disease progression or study discontinuation for any other reason.  The primary endpoints of the study include evaluating the safety and tolerability and the pharmacokinetics of CUDC-427 in people with solid tumors or lymphoma and determining the maximum-tolerated-dose and a potential recommended dose for further clinical studies.  Secondary endpoints include a preliminary assessment of anti-tumor activity of CUDC-427 and evaluating pharmacodynamic markers.  Genentech plans to present full study results at a medical conference in mid-2013.  Please refer to http://www.clinicaltrials.gov for additional study details.

About Inhibitor of Apoptosis Proteins

Impairment of programmed cell death or apoptosis often contributes to the formation and progression of cancer, and evasion of apoptosis is one of the primary strategies by which cancer cells develop resistance to anticancer therapies.  Inhibitor of apoptosis (IAP) proteins are a family of functionally and structurally related proteins which include X-linked IAP (XIAP), cellular IAPs (cIAP1 and cIAP2), and melanoma IAP (ML-IAP). They confer protection from death-inducing stimuli by exerting a range of biological activities that promote cancer cell survival and proliferation.  Some even directly inhibit caspases, critical players in the execution of apoptosis.

Mutations, amplifications and chromosomal translocations of IAP genes are associated with various solid and hematologic cancer types, and increased IAP expression has been associated with an unfavorable prognosis and poor outcome for patients.  As a consequence, IAP proteins are considered promising molecular targets for anticancer therapy.

Cancer is just as deadly as it was 50 years ago. Here’s why that’s about to change.


 

 

Why haven’t we cured cancer yet? It seems like almost every day, we hear about another miraculous advance in cancer treatment. Drugs that cause tumors to shrink, gene therapies, and even a possible vaccine. And yet, our loved ones keep dying of cancer.

We spoke to cancer experts to find out why the death rate from cancer hasn’t changed in the past 50 years — and we learned how genetic therapies could transform cancer treatments tomorrow.

Cannabis-Linked Cell Receptor Might Help Prevent Colon Cancer


The study was published in the Aug. 1 issue of the journal Cancer Research.

A cannabinoid receptor lying on the surface of cells may help suppress colorectal cancer, say U.S. researchers. When the receptor is turned off, tumor growth is switched on. Cannabinoids are compounds related to the tetrahydrocannabinol (THC) found in the cannabis plant.

 

It’s already known that the receptor, CB1, plays a role in relieving pain and nausea, elevating mood and stimulating appetite by serving as a docking station for the cannabinoid group of signaling molecules. This study suggests that CB1 may offer a new path for cancer prevention or treatment.

 In the study of human colorectal tumor specimens, the researchers also found that the drug decitabine can restore CB1 expression.In addition, mice those are prone to developing intestinal tumors and also have functioning CB1 receptors developed fewer and smaller tumors when treated with a drug that mimics a cannabinoid receptor ligand, the researchers found. Ligands are molecules that function by binding to specific receptors.

This therapy may help the cancer research team to found out the caner in early stage.

Tetrahydrocannabinol
(−)-(6aR,10aR)-6,6,9-trimethyl-
3-pentyl-6a,7,8,10a-tetrahydro-
6H-benzo[c]chromen-1-ol

Tetrahydrocannabinol (THC), or more precisely its main isomer (−)-trans-Δ9-tetrahydrocannabinol ((6aR,10aR)-delta-9-tetrahydrocannabinol), is the principal psychoactive constituent (or cannabinoid) of the cannabis plant. First isolated in 1964, in its pure form, by Israeli scientists Raphael Mechoulam, Yechiel Gaoni and colleagues at the Hebrew University of Jerusalem, it is a glassy solid when cold, and becomes viscous and sticky if warmed. A pharmaceutical formulation of (−)-trans-Δ9-tetrahydrocannabinol, known by its INN dronabinol, is available by prescription in the U.S. and Canada under the brand name Marinol. An aromatic terpenoid, THC has a very low solubility in water, but good solubility in most organic solvents, specifically lipids and alcohols.

Like most pharmacologically-active secondary metabolites of plants, THC in cannabis is assumed to be involved in self-defense, perhaps against herbivores. THC also possesses high UV-B (280–315 nm) absorption properties, which, it has been speculated, could protect the plant from harmful UV radiation exposure.

Tetrahydrocannabinol with double bond isomers and their stereoisomers is one of only three cannabinoids scheduled by Convention on Psychotropic Substances (the other two are dimethylheptylpyran and parahexyl). Note that cannabis as a plant is scheduled by Single Convention on Narcotic Drugs (Schedule I and IV).

Promising Antiviral Compounds Discovered


Scientists sifted through thousands of potentially efficacy compounds and managed to identify two promising candidates for the development of drugs against human adenovirus, a cause of ailments ranging from colds to gastrointestinal disorders to pink eye

Scientists at the U.S. Department of Energy’s Brookhaven National Laboratory have identified two promising candidates for the development of drugs against human adenovirus, a cause of ailments ranging from colds to gastrointestinal disorders to pink eye. A paper published in FEBS Letters, a journal of the Federation of European Biochemical Societies, describes how the researchers sifted through thousands of compounds to determine which might block the effects of a key viral enzyme they had previously studied in atomic-level detail.
