Grünenthal has Acquired US-based Thar Pharmaceuticals Inc. to Expand its Development Portfolio of Treatment Options for CRPS (Complex Regional Pain Syndrome), a Serious, Disabling Orphan Disease

AACHEN, Germany and PITTSBURGH, November 16, 2016 /PRNewswire/ --

- The acquisition supports Gruenenthal's commercial and R&D strategy to drive
innovation in pain. 
- Thar Pharmaceutical's lead compound, T121, complements Gruenenthal's existing
development pipeline and the goal of delivering innovative and effective treatments to
patients with CRPS. 
- Patients with Complex Regional Pain Syndrome (CRPS), an orphan disease, suffer from
severe, persistent pain and a variety of other disabling symptoms.  
- There is a significant unmet medical need for those suffering from CRPS. Classic
analgesics offer only limited symptomatic relief; there are no sufficiently effective
treatment options available.  
- There are no FDA or EMA approved drug treatments for CRPS. 

Gruenenthal, an R&D-driven, privately held international pharmaceutical company with headquarters in Germany, has announced its recent acquisition of Thar Pharmaceuticals, a US-based clinical-stage, specialty pharmaceutical company. Thar Pharmaceuticals focused on transforming IV-only drugs into oral drugs for existing and new indications using its proprietary technology Enhance[TM] development platform. With this acquisition, Gruenenthal has obtained the worldwide development and commercialization rights for Thar Pharmaceutical's lead development candidate, T121.

T121 is a novel, Phase III-ready, composition-of-matter patented oral zoledronic acid drug product. It has received orphan drug designation by the U.S. Food and Drug Administration. T121 complements and broadens Gruenenthal's portfolio for CRPS, which includes IV neridronate that is currently in phase III clinical development.

Gruenenthal will conduct clinical phase III development to demonstrate efficacy and safety of T121 for the treatment of patients with CRPS. Preclinical[1] and pilot clinical [2] evidence suggest that zoledronic acid could significantly reduce pain and other debilitating symptoms of CRPS.

"Gruenenthal is highly dedicated to improving the life of patients with pain and orphan diseases that have limited treatment options", said Gabriel Baertschi, CEO of the Gruenenthal Group. "As global leader in pain, we strive to develop innovative, life-changing products. This acquisition fully supports our strategy to become a leading player in CRPS (Complex Regional Pain Syndrome)."

 "We are expanding our development portfolio for treating patients with orphan, disabling diseases. For CRPS, an often debilitating, extremely painful syndrome, truly efficacious treatments are lacking today", explained Dr. Klaus-Dieter Langner, Chief Scientific Officer of Gruenenthal. "With the successful development of our expanded portfolio, oral T121 and IV neridronate, Gruenenthal seeks to offer CRPS patients new hope for the future. Our teams are highly motivated and will use all of their knowledge, experience and resources to bring these promising treatments to market for patients as soon as possible."

"We are very proud of what our team of employees, advisors, partners and investors has accomplished in driving our T121 lead product from an idea to the initiation of Phase 3 development for the treatment of Complex Regional Pain Syndrome," stated the former Thar Pharmaceuticals board chairman,                  Dr. Lalit Chordia.  Raymond K. Houck, former President and Chief Executive Officer of Thar Pharmaceuticals, added, "We believe Gruenenthal is an exceptional strategic fit for Thar's T121. Gruenenthal combines world-leading knowledge and expertise in CRPS with the resources, motivation and dedication to successfully develop and commercialize our potential first-in-class, non-opioid oral treatment to improve the lives of CRPS patients. Gruenenthal's track record of bringing innovative pain treatments to patients around the globe underscores that we have chosen the right partner". 

Locust Walk acted as lead financial advisor to Thar on this transaction. SunTrust Robinson Humphrey, Inc. served as co-financial advisor to Thar, and Goodwin Procter LLP served as its legal advisor.

About CRPS 

Complex Regional Pain Syndrome (CRPS) is a debilitating condition characterized by severe, continuous, burning or throbbing pain often occurring in an extremity after injury or surgery. The excessive pain is accompanied by changes in skin colour, temperature and/or swelling/edema. It is persistent, considered to be one of the most painful conditions, results in loss of physical function, and can lead to significant and sometimes permanent disability. There are currently no FDA- or EMA-approved treatments for CRPS.
