Alopecia - Hair Loss

2006-05-05T17:07:41Z

210.214.44.53:

== Rationale ==
* “Medication for men plagued by hair loss has become a topic of interest in Japan since a drug company began marketing it at the end of last year." March 5th, 2006 – [http://stophair.setupmyblog.com/?p=55]

* “An increasing number of companies are apparently turning the Chinese fear of a bald spot into big bucks with some doing so well they are branching out into other countries.” February 16, 2006 – [http://stophair.setupmyblog.com/]

== Introduction ==

=== Hair Basics ===
* Hair is a complex and delicate part of the body
* Keeping it healthy and beautiful is a challenge
* Structure of Hair root - [http://www.follicle.com/hair-structure-life-cycle.html]
* Structure of Hair bulb - [http://www.pg.com/science/haircare/hair_twh_12.htm]
[[Image:Hairbasics.jpg|thumb|center|500px|Structure of Hair root and Hair bulb]]

=== Reasons for Hair loss ===
[[Image:Facts.jpg|thumb|right|400px|Survey results from Japan]]
Both men and women lose hair for similar reasons. Hair loss in men is often more dramatic, and follows a specific pattern of loss which has been termed “Male Pattern Baldness” (Androgenetic Alopecia).

'''Main reasons'''
* Hormonal effect of androgen
* Reduction of blood circulation around hair follicle
* Deactivation of hair matrix cells

'''Some facts from Japan'''

* Market size: ¥ 30 Billion
* Number of products: more than 100

(JICST-EPlus - Japanese Science & Technology)

== Goals ==

The goal of this report is to:
* Summarize IP activity over the years
* Identify major players
* Conduct patent analysis
a) Composition
b) Nature
c) Action

'''And then'''

* Analyze patents pertaining to high sebum activity

== Approach ==

* A broad search was conducted on hair loss patents.
* Patent information was sourced through SIP.
* A set of patents was selected for analysis.

Composition of treatment for causes are identified and categorized as follows:

* Anti-androgen
* Minoxidil
* Double action (Anti-androgen + Mindoxidil)
* Hair matrix cells activator
* Sebum production inhibitor

== IP activity over years ==
The graph indicates:
* Number of patents filed every 5 years (except for first 7 years).
* First solution proposed in 1973
* Filing trend indicates steep rise in activity recently.

== Major Players ==
[[Image:players.jpg|thumb|left|400px|Assignees with more than 20 patents ]]
[[Image:players1.jpg|thumb|center|400px|Assignees with fewer than 20 patents ]]

* '''Active Assignees'''
Assignees currently active with more than 5 patents to their credit during 2000-2005.
* Warner with 9 patents,
* Bristol with 6 and
* Abbott with 5.

[[Image:Active.jpg|thumb|center|500px|Active Assignees]]

== Anti-androgens ==
* Anti-androgen is a substance that inhibits biological effects of androgenic hormones
* 5-alpha reductase + Testosterone = Dihydrotestosterone (DHT)
* DHT attaches to an Androgen Receptor.
* DHT causes increase in hair loss and gradual miniaturization of the follicle, which eventually dies resulting hair loss

== Minoxidil ==
* A thick network of tiny veins and arteries lines the outer wall of the follicle. Blood pumps through the bulb and hair via this network
* Minoxidil dilates blood vessels; which is also called as “potassium channel opener”
* Minoxidil sulfate (MS) appears to be the active metabolite responsible for hair growth stimulation.

== Hair matrix cell activator ==
* Stem cells of the hair follicle are gathered in the basal layer of the outer root sheath bulge.
* It is from these cells that matrix cells are formed.
* Growth and differentiation of the matrix cells are under the influence of substances produced by cells of the dermal papilla.

== Sebum Production Inhibitor ==
* Sebum, a complex mixture of lipid substances, is secreted from sebaceous glands associated with hair follicles.
* The inhibitor blocks the excessive sebum production produces greasy effect on hair and scalp and also responsible for thinning and loosing of hair.

== New Combinations based on IP study? ==

Yes, new Combinations can be made with '''natural products''' based on IP study
* Walnut extract containing [[Image:5ar.jpg]] inhibitor (as anti-androgen) and Flavnones (for vasodilation).
* Sophora Flavnones (for vasodilation) in combination with Saw Palmetto berry (as anti-androgen).

'''Note:''' The above combinations are based on limited study and are only possible examples

== IP studies provides ==

=== Technology trends ===
* Use of saw palmetto berry for treating alopecia was first patented in 1996.
* Since then, 144 patents (including family patents) have been filed till 2006.
* Most patents use saw palmetto berry in combination with other products.

=== New opportunities ===
Yes, the IP studies provide new opportunities in the following area.
* Sophora Flavescens contain flavnoids.
* Natural extract Sophora Flavescens cited in LG patent of 2001.
* Research shows fewer than 7 patents based on Sophora Flavescens for hair loss or alopecia.

== Conclusions ==
* Hair loss medication is a very active area of research and intellectual property development.
* One of the most promising areas of development is the area of Anti-androgens.
* The top companies are Merck, L’Oreal and Smithkline.
