Is a cure for Alopecia Areata on the horizon? New research shows promise

22 Mar Is a cure for Alopecia Areata on the horizon? New research shows promise

Alopecia Areata is an autoimmune / polygenic skin disease that causes loss of hair on the scalp and face and is estimated to affect over 6.8 million people in the U.S alone. There is currently no cure available for this disorder, with dermatologists using Corticosteroids, Minoxidil 5%, Anthralin and Diphencyprone (DPCP) as treatment options. However, these cause discomfort and side effects leading to low patient adherence. Alopecia areata is one of eight new disease areas selected by the FDA in 2015 that it will focus on under its Patient-Focused Drug Development Initiative (PFDDI).

This disorder can cause a severe emotional impact on the patient as it has social implications and can lead to isolation and stigma, it may even adversely affect the ability to form and sustain relationships. The alopecia industry has faced challenges in achieving proof of concepts (PoC), as patient responses to therapy are highly individualized with some of them experiencing spontaneous remission. However, recent scientific advancements have shown that new research such as T-cell mediated mechanisms can achieve faster PoC’s.

Grand View Research Inc. estimates that the global alopecia treatment market will reach USD 11.8 billion by 2024. The rise in disposable incomes, increasing health awareness being made possible by organizations such as National Alopecia Areata Foundation (NAAF) and the American Hair Loss Association and the rise in research and development efforts will propel the growth in the market. Many branded products are heading towards patent expiry that could attract an onslaught of generics and act as a hindrance for further innovation.

Tropical applications are the most preferred form of treatment because of their ease of use and non-invasive nature; however the introduction of novel treatment options such as Janus kinase inhibitors (JAK) that can stimulate follicle growth with minimal side effects have the potential to change the therapeutic market. The cost of treatment is still deemed prohibitive and can hamper the growth rate of the industry.

We take a look at some companies which are striving to address the needs of the patients in this field:

Concert Pharmaceuticals (NASDAQ: CNCE)

The company is a pioneer that uses its proprietary DCE Platform® (deuterated chemical entity) to improve the pharmacokinetic or metabolic properties of approved drugs in the field of autoimmune and central nervous system disorders. The company intends to leverage on its ability to create deuterated versions of known drugs thereby achieving faster clinical proof-of-concept and clinical success on one hand and enhanced oral bioavailability, improved metabolic profile and longer half-life’s of the compounds on the other.

Deuterium is non-radioactive and safe and can be isolated from sea water. It is naturally occurring in abundance, even in the human body, and hence used in human and metabolic studies. It possesses double the atomic mass of hydrogen which enables it to form potent bonds with carbon and makes it an ideal candidate for drugs that are metabolized by pathways characterized by scission of carbon-hydrogen bonds.

It is developing CTP-543, an oral selective inhibitor of certain Janus kinases, known as JAK1 and JAK2 for treatment of Alopecia, by modifying ruxolitinib being marketed in the U.S under the brand name Jakafi® for the treatment of myelofibrosis and polycythemia vera which is currently undergoing Phase 2a clinical trials. In addition, it is also working on CTP-692, a novel drug for adjunctive treatment of schizophrenia.

The company’s novel DCE Platform® is protected by 114 issued US patents or patent applications that claim deuterated analogs of more than 90 non-deuterated drugs and drug candidates. The company has strategic collaborations with leading biopharmaceutical companies such as Celegene (NASDAQ: CELG) for developing CTP-730, a product candidate containing deuterated apremilast for the treatment of inflammatory diseases, Jazz Pharmaceuticals (NASDAQ: JAZZ) for the development of a once nightly sodium oxybate product and Avanir Pharmaceuticals, acquired by Otsuka Pharmaceuticals Co. Ltd., for developing AVP-786 for the treatment of agitation associated with Alzheimer’s disease.

The company also has an asset purchase agreement with Vertex for CTP-656, an investigational cystic fibrosis transmembrane conductance regulator (CFTR) potentiator.
