To a solution of (4-cyclopropanesulfonylphenyl)-(2,4-difluorophenoxy)acetic acid (obtained in example Al -step III) in ethyl acetate was added (S)-(-)-l-phenylethylamine drop wise at -15 °C. After completion of addition the reaction was stirred for 4-6 hours. Solid was filtered and washed with ethyl acetate. The solid was then taken in IN HCl and extracted with ethyl acetate, ethyl acetate layer was washed with brine, dried over anhydrous sodium sulfate. Solvent was removed under reduced pressure to obtain (-)-(4- cyclopropanesulfonylphenyl)-(2,4-difluorophenoxy)acetic acid. Enantiomeric enrichment was done by repeating the diasteriomeric crystallization. [α]23 589 = – 107.1 ° (c = 2%Chloroform) Enantiomeric purity > 99. % (chiral HPLC)

Stirring was continued for 1 hour at the same temperature. The resulting mixture was further cooled to -35 °C, and to that, a solution of excess (2- amino-5-chlorothiazol-4-yl)acetic acid ethyl ester in DCM was added drop wise. After completion of reaction, the reaction mixture was poured into IN aqueous HCl under stirring, organic layer was washed with IN HCl, followed by 5% brine, dried over anhydrous sodium sulfate, solvent was removed under reduced pressure to get the crude compound which was purified by preparative TLC to get the title compound.

Advinus’ GK-activator Achieves Early POC for Diabetes

November 29 2011

Partnership Dialog Actively Underway

Advinus Therapeutics, a research-based pharmaceutical company founded by globally experienced industry executives and promoted by the TATA Group, announced that it has successfully completed a 14-day POC study in 60 Type II diabetic patients on its lead molecule, GKM-001, a glucokinase activator. The results of the trial show effective glucose lowering across all doses tested without any incidence of hypoglycemia or any other clinically relevant adverse events.

The clinical trials on GKM-001 validate the company’s pre-clinical hypothesis that a liver selective Glucokinase activator would not cause hypoglycemia (very low blood sugar), while showing robust efficacy.

“GKM-001 is differentiated from most other GK molecules that are in development, or have been discontinued, due to its novel liver selective mechanism of action. GKM-001 has a prolonged pharmacological effect and a half-life that should support a once a day dosing as both mono and combination therapy.” said Dr. Rashmi Barbhaiya, MD & CEO, Advinus Therapeutics. He added that Advinus is actively exploring partnership options to expedite further development and global marketing of GKM-001.

GKM-001 belongs to a novel class of molecules for treatment of type II diabetes. It is an activator of Glucokinase (GK), a glucose-sensing enzyme found mainly in the liver and pancreas. Being liver selective, GKM-001 mostly activates GK in the liver and not in pancreas, which is its key differentiation from most competitor molecules that activate GK in pancreas as well. The resulting increase in insulin secretion creates a potential for hypoglycemia-a risk GKM-001 is designed to avoid. Advinus has the composition of matter patent on GKM-001 for all major markets globally. Both the Single Ascending Dose data, in healthy and type II diabetics, and the Multiple Ascending Dose Study in Type II diabetics has shown that the molecule shows effective glucose lowering in a dose dependent manner and has excellent safety and tolerability profile over a 40-fold dose range. The pharmacokinetic properties of the molecule support once a day dosing. GKM-001 has the potential to be “First-in-Class” drug to address this large, growing and yet poorly addressed market.

Advinus also has identified a clinical candidate as a back-up to GKM-001, which is structurally different. In its portfolio, the company has a growing pipeline for COPD, sickle cell disease, inflammatory bowel disease, type 2 diabetes, acute and chronic pain and rheumatoid arthritis in various stages of late discovery and pre-clinical development.

About the Diabetes Market:

The present 300 million diabetics population is estimated to jump to 450 million by 2030 worldwide. A large proportion of these patients are poorly controlled despite multiple therapies. Total sales of diabetic prescription products were $32 billion in 2010.

Advinus Therapeutics team discovers novel molecule for treatment of diabetes

  • The first glucokinase modulator discovered and developed in India 
  • A new concept for the management of diabetes for patients, globally 
  • 100 per cent ‘made in India’ molecule for the treatment of diabetes 
  • IND approved by DGCI, Phase I clinical trial shows excellent safety and tolerance profiles with efficacy

Bangalore: Advinus Therapeutics (Advinus), the research-based pharmaceutical company founded by leading global pharmaceutical executives and promoted by the Tata group, today, announced the discovery of a novel molecule for the treatment of type II diabetes — GKM-001.The molecule is an activator of glucokinase; an enzyme that regulates glucose balance and insulin secretion in the body.

GKM-001 is a completely indigenously developed molecule and the initial clinical trials have shown excellent results for both safety and efficacy.

“Considering past failures of other companies on this target, our discovery programme primarily focused on identifying a molecule that would be efficacious without causing hypoglycaemia; a side effect associated with most compounds developed for this target.

“Recently completed Phase I data indicate that Advinus’ GKM–001 is a liver selective molecule that has overcome the biggest clinical challenge of hypoglycaemia. GKM-001 is differentiated from most other GK molecules in development due to this novel mechanism of action,” said Dr Rashmi Barbhaiya, MD and CEO, Advinus Therapeutics.

He further added, “We are very proud that GKM-001 is 100 per cent Indian. Advinus’s discovery team in Pune discovered the molecule and entire preclinical development was carried out at our centre in Bangalore. The Investigational New Drug (IND) application was filed with the DGCI for approval to initiate clinical trials in India within 34 months of initiation of the discovery programme. Subsequent to the approval of the IND, we have completed the Phase I Single Ascending Dose study in India within two months.”

GKM-001 is a novel molecule for the treatment of type II diabetes. It is the first glucokinase modulator discovered and developed in India and has potential to be both first or best in class. The success in discovering GKM-001 is attributed to the science-driven efforts in Advinus laboratories and ‘breaking the conventional mold’ for selection of a drug candidate. Advinus has ‘composition of matter’ patent on the molecule for all major markets globally. Glucokinase as a class of target is considered to be novel as currently there is no product in the market or in late clinical trials. The strategy for early clinical development revolved around assessing safety (particularly hypoglycaemia) and early assessment of therapeutic activity (glucose lowering and other biomarkers) in type II diabetics. The Phase I data, in both healthy and type II diabetics, shows excellent safety and tolerability over a 40-fold dose range and desirable pharmacokinetic properties consistent with ‘once a day’ dosing. The next wave of clinical studies planned continues on this strategy of early testing in type II diabetics.

Right behind the lead candidate GKM-001, Advinus has a rich pipeline of back up compounds on the same target. These include several structurally different compounds with diverse potency, unique pharmacology and tissue selectivity. Having discovered the molecule with early indication of wide safety margins, desired efficacy and pharmacokinetic profiles, the company now seeks to out-licence GKM-001 and its discovery portfolio.
