Nabilone Drug offers new pain management therapy for diabetics.....

We know that, Nabilone is a synthetic cannabinoid with therapeutic use as an antiemetic and as an adjunct analgesic for neuropathic pain. It is a synthetic cannabinoid, which mimics the main chemical compound of cannabis(THC). Chemically, nabilone is similar to the active ingredient found in naturally occurring Cannabis sativa L. 

In Canada, the United States, the United Kingdom and Mexico, nabilone is marketed as Cesamet. It was approved in 1985 by the U.S. Food and Drug Administration (FDA) for treatment of chemotherapy-induced nausea and vomiting that has not responded to conventional antiemetics. Though it was approved by the FDA in 1985, the drug only began marketing in the United States in 2006. It is also approved for use in treatment of anorexia and weight loss in patients with AIDS.

Although it doesn't have the official indication (except in Mexico), nabilone is widely used as an adjunct therapy for chronic pain management. Numerous trials and case studies have demonstrated various benefits for conditions such as fibromyalgia  and multiple sclerosis. Nabilone is a racemic mixture consisting of the (S,S) and the (R,R) isomers ("trans") ......

Dulaglutide Fares Well in New Trials

Eli Lilly and Co.'s potential once-weekly treatment for type 2 diabetes fared better than three other drugs in lowering blood sugar levels, according to initial results from some late-stage research.

The Indianapolis drugmaker said that two doses of its injectable drug dulaglutide (see structure) delivered statistically superior reductions in blood sugar levels when compared to twice-daily injections of exenatide and the oral treatments metformin and sitagliptin. Lilly will present more details from the studies at scientific meetings next year and in 2014.

Lilly said it will submit the drug to regulators for approval next year. It said timing in the United States will depend on the completion of Food and Drug Administration requirements for an assessment of the drug's cardiovascular risk.

Bayer Releases Riociguat Data

We  know that,  Riociguat (BAY 63-2521, below structure) is a novel drug that is currently in clinical development by Bayer. It is a stimulator of soluble guanylate cyclase (sGC). At the moment Phase III clinical trials investigate the use of riociguat as a new approach to treat two forms of pulmonary hypertension (PH): chronic thromboembolic pulmonary hypertension (CTEPH) and pulmonary arterial hypertension (PAH). Riociguat constitutes the first drug of a novel class of sGC stimulators.

FDA Clears Eisai’s Epilepsy Drug Fycompa

We know that, Fycompa (see structure, perampanel) is a selective, non-competitive AMPA receptor antagonist discovered by the research teams at Eisai laboratories. The development of an AMPA antagonist compound with a favourable pharmacokinetic and safety profile arose after the AMPA receptor was identified as a promising target for drug development. The AMPA receptor is widely present in almost all excitatory neurons. It is believed to play a role in a large number of central nervous system diseases with similar neuropathology.

Positive Results from Phase 2 Trial of Oral Calcitonin | News | Drug Discovery and Development Magazine

Tarsa Therapeutics Inc. announced that a Phase 2 trial of its oral recombinant salmon calcitonin in the prevention of postmenopausal osteoporosis was successfully concluded and yielded statistically significant, clinically relevant improvements in bone mineral density (BMD) at the lumbar spine.  These data were presented at the American Society for Bone and Mineral Research (ASBMR) 2012 Annual Meeting by Phase 2 investigator Neil Binkley, MD, who is an associate professor of endocrinology and Geriatrics at the University of Wisconsin School of Medicine and Public Health in Madison, Wisconsin.....

T-DM1 Extends Overall Survival | News | Drug Discovery and Development Magazine

We know that,Trastuzumab emtansine (INN, also called trastuzumab-DM1 or trastuzumab-MCC-DM1, abbreviated T-DM1) is an antibody-drug conjugate consisting of the antibody trastuzumab (the active ingredient in Herceptin) linked to a cytotoxic agent that is a derivative of maytansine (DM1).

It is in clinical trials for breast cancer, especially of the HER2 positive type. Early results in Nov 2011 from an open-label phase II trial on 137 patients with HER2-positive advanced breast cancer were very encouraging.

EMILIA, a phase III trial of 991 people with HER2-positive unresectable locally advanced or metastatic breast cancer, comparing T-DM1 versus capecitabine plus lapatanib in patients previously treated with trastuzumab and a taxane chemotherapy, showed improved progression free survival in patients treated with T-DM1 (median 9.6 vs. 6.4 months) with an improved safety profile. The study sponsor reported in August 2012 that T-DM1 significantly improved survival in the EMILIA study and that the details will be reported at an upcoming medical meeting

Empagliflozin Lowers Blood Pressure | News | Drug Discovery and Development Magazine

We know that, Empagliflozin (see structure) is a SGLT2 inhibitor which is being investigated in clinical trials for the oral treatment of type 2 diabetes by Boehringer Ingelheim and Eli Lilly and Company. It is an inhibitor of the sodium glucose co-transporter-2 (SGLT-2), which is found almost exclusively in the proximal tubules of nephronic components in the kidneys. SGLT-2 accounts for about 90 percent of glucose reabsorption into the blood. Blocking SGLT-2 causes blood glucose to be eliminated through the urine via the urethra...

Synta announces results from ganetespib Phase 2b trial on NSCLC

In continuation of my update on Ganetespib....

"The preliminary results from GALAXY indicate that the addition of ganetespib to docetaxel is well tolerated and may improve outcomes in patients compared to docetaxel alone," said Dr. Ramalingam, a Principal Investigator of the study. "This includes promising improvements in survival seen across the broad adenocarcinoma population as well as in key predefined patient populations. A well-tolerated combination regimen that extends survival associated with salvage therapy in NSCLC will meet a much awaited need to improve the current standard of care."

As per the CEO's statement "the objective of the interim analysis was to identify the best choice of patient population and trial design for transitioning to the Phase 3 stage of the study. The broad-based activity seen in the results presented  support advancing into the Phase 3 stage in alladenocarcinoma patients. The results have yielded a rich data set which we are using to optimize and de-risk the Phase 3 stage of the program. We are hopeful that this next stage of development will lead to a new treatment option for patients fighting this devastating disease."

Enrollment completion of the Phase 2b stage of the GALAXY trial and the transition to the Phase 3 stage are expected later this year. Based on current assumptions, the Company anticipates that Phase 3 will enroll approximately 500 adenocarcinoma patients, with overall survival as a primary endpoint. Biomarker findings and other patient selection and treatment experience from the Phase 2b stage will be incorporated into the design of the Phase 3 stage. An announcement with additional Phase 3 details is anticipated later this year, following discussion with regulatory agencies.

Drug combinations show promise against metastatic melanoma

In continuation of my update on Vemurafenib..

A Phase I study in 44 patients shows that the combination of the MEK inhibitor GDC-0973  (see structure) and vemurafenib can be delivered safely, Dr Rene Gonzalez of the University of Colorado Cancer Center, Denver, and colleagues report.

"BRAF inhibition has resulted in high response rates and improved survival in patients with BRAF mutated melanoma," Dr Gonzalez said. "One of several mechanisms of resistance has been reactivation of the MAPK pathway. Preclinical models show that combined inhibition of BRAF and MEK can delay the acqusition of resistance compared to BRAF inhibitor monotherapy. Inhibition of the pathway downstream from BRAF with the MEK inhibitor GDC-0973 could theoretically overcome or delay this resistance mechanism and improve outcomes."

The study was not designed to evalate efficacy. "While early data in a small number of patients did show tumor reduction, it would be premature to comment on efficacy based on these preliminary results and further research is warranted," Dr Gonzalez said.
