Its backers include New Enterprise Associates, Adage Capital Management, RA Capital Management, Pappas Ventures, RiverVest Venture Partners and Alta Partners.
DUBLIN and SAN DIEGO, May 12, 2014 /PRNewswire/ —
Shire plc (LSE: SHP, NASDAQ: SHPG) and Lumena Pharmaceuticals, Inc., a biopharmaceutical company with rare disease pipeline assets, announce the acquisition of Lumena Pharmaceuticals by Shire.
Chief Executive of Shire, Flemming Ornskov, MD comments:
“Our pipeline and strategic focus on rare diseases is even further strengthened with the acquisition of Lumena Pharmaceuticals, which also complements our strong GI presence. These attractive potential treatments may offer new hope to patients with rare cholestatic liver disease and further contribute to Shire’s future growth. We are excited by the possibilities of these new assets in liver disease. We have the resources, the infrastructure and the operating capacity to invest in these new potential growth drivers which add further value to Shire’s innovative pipeline.”
President and CEO of Lumena Pharmaceuticals, Mike Grey comments:
“I believe that this transaction is a significant win for all parties involved, especially the patients, and the future of LUM001 as a treatment for rare cholestatic liver diseases looks brighter than ever. Shire has deep rare disease experience, a global infrastructure, and the commercial expertise to deliver LUM001 to patients around the world. The Lumena team will work closely with Shire to finish the ongoing Phase 2 clinical programs as part of our commitment to the patient populations we have championed since we formed Lumena Pharmaceuticals.”
Strategic rationale and background on Lumena Pharmaceuticals
The acquisition of Lumena strengthens Shire’s already valuable and robust pipeline. It complements Shire’s strategic focus on Rare Diseases and provides a future growth path for Shire’s Gastrointestinal business, which generated revenues of over $800 million in 2013. In acquiring Lumena, Shire is gaining experience in liver disease with the opportunity to leverage its existing GI commercial infrastructure. In addition, there is a good fit with Shire’s recent acquisition of Fibrotech, which has brought pipeline programs to address unmet patient need in other fibrotic conditions including renal impairment.
Lumena Pharmaceuticals brings to Shire two new oral therapeutic compounds; LUM001, in Phase 2 with four potential orphan indications and LUM002, ready to enter Phase 2 later in 2014.
LUM001 and LUM002 are both inhibitors of the apical sodium-dependent bile acid transporter (ASBT), which is primarily responsible for recycling bile acids from the intestine to the liver. Blocking bile acid transport with ASBT inhibitors reduces bile acid absorption and has the potential to improve liver function and relieve disease symptoms (such as extreme itching associated with cholestatic liver diseases), and may slow disease progression.
These rare cholestatic liver diseases are primarily treated by hepatologists and gastroenterologists and can be covered by a small, specialty sales force consistent with Shire’s model.
Shire does not expect the acquisition of Lumena to result in a change to its previously stated earnings guidance for 2014.
LUM001 is a novel, once-daily, orally-administered, potent and selective ASBT inhibitor that works by preventing recycling of bile acids back to the liver and is thought to reduce bile acid accumulation, improve liver function and potentially relieve the extreme itching associated with cholestatic liver disease.
LUM001 is currently in Phase 2 clinical development for four rare cholestatic liver disease indications; two pediatric and two adult with a potential 2016 launch. These potential indications are: Alagille syndrome (ALGS), progressive familial intrahepatic cholestasis (PFIC), primary biliary cirrhosis (PBC) and primary sclerosing cholangitis (PSC).
Some of the key characteristics of cholestatic liver diseases are elevated bile acids, leading to progressive liver damage that can cause liver failure, and pruritus, or severe itching. Pruritus is generally the most debilitating symptom afflicting children and adults with these diseases.
Surgical intervention, which lowers bile acid levels, has been shown to relieve symptoms and slow disease progression in patients with ALGS and PFIC – this is currently the only treatment option for these patients. Patients with cholestatic liver diseases may ultimately require liver transplants.
By reducing serum bile acids, LUM001 may offer a novel therapeutic approach for alleviating the pruritus and progressive liver damage associated with cholestatic liver diseases.
The prevalence of each of the four diseases is as follows:
Indication US prevalence EU prevalence
3 per 100,000
ALGS 9476 individuals 3 per 100,000
<1 per 100,000
PFIC 3159 individuals 1 per 100,000
40 per 100,000
PBC 126,979 individuals 30 per 100,000
14 per 100,000
PSC 44,222 individuals 3 per 100,000
(Source: Lumena Pharmaceuticals Applications for Orphan Designation):
LUM001 has received orphan drug designation for all four potential indications in both the United States and the European Union.
LUM002 is a novel, once daily, orally-administered, highly potent and selective inhibitor of ASBT, in development for the treatment of nonalcoholic steatohepatitis (NASH), a common and often “silent” liver disease characterized by fat deposits in the liver and inflammation which can progress to significant fibrosis.
While the underlying cause of liver injury in NASH is not fully known, it is strongly associated with obesity, Type 2 diabetes, high cholesterol and triglycerides, and other metabolic disorders. Approximately 6 million individuals in the US are estimated to have progressed to NASH and some 600,000 to NASH-related cirrhosis (Source: World Gastroenterology Organisation Global Guidelines June 2012).
By blocking bile acid reabsorption, LUM002 is thought to modulate colonic bile acid concentrations and receptor signaling on cells in the lower portion of the GI tract. This signaling is believed to result in the secretion of peptides that regulate insulin release from the pancreas, glucose metabolism and the synthesis of cholesterol and fatty acids.
Therapeutic strategies aimed at modulating insulin resistance and normalizing lipoprotein metabolism have significant potential to benefit patients with NASH.
Phase 1 safety trials in healthy volunteers and a Phase 1b trial in patients with metabolic disease have been completed. The next step is to initiate a Phase 2 clinical trial in patients with NASH – anticipated to begin in the second half of 2014.
