Sirna Update

Yeah, I understand the RNA interference stuff. I apologize for not be more precise with my words,jme1.

I’m hoping right along with the rest of you that they get a delivery system that works for hair removal. I hope there is a real interest in this one. Just call me “Debbie Downer – wah-wah”. My kids do it (with love) and so can you since I’m now desensitized by the comment. :wink:

Well, I’m a bit doubtful on this as well…only for the fact that it’s been so quiet. Right now I see it as 50/50. They have proven the technology works in in vitro and in vivo studies. They have proven it with other trials they have done up until now. I just wish there would be some news. In January, Sirna/Merck’s application to begin clinical trials for hair removal was in progress. Nothing has come about since.

I know jeffk has been pretty good about finding info, perhaps if he sees this he will chime in on anything he might have ran across recently.

Hi all,
Just thought I would share an email I sent to the leading scientist in this feild (as well as Sirna and Merck), Dr. A Christiano of which she was kind enough to reply to! :slight_smile: Seems like she is still working hard on the problem:

"Thank you for copying me on your incredibly eloquent email to
Merck/Sirna.

I had no idea people like yourself were following this work so
closely…I’ve read some of the hairtell stories, and I am humbled and deeply moved by them.

Would you mind if I share your email with a few other people?

Thank you again for taking the time to write such an impassioned
letter to Merck. It means the world to me to know that our little bit of research may someday impact people’s lives and well-being for the better.

Please keep in touch,
warmest regards,
angela

I sent Dr.Christiano a post from a very depressed poster,“MikeP”, entitled “Re: Male with fur” in 2006, but I got no reply. My hope was to keep her involved with her research. Here’s the whole thread: http://www.hairtell.com/forum/ubbthreads.php?ubb=showflat&Board=1&Number=35914&Searchpage=1&Main=7599&Words=christiano&topic=0&Search=true#Post35914

I’m glad you received such a warm reply Eddy, because that tells us now that she is aware of real people who come to hairtell with real hair problems. I highlighted a paragraph below in bold print so you can see what I am referring to. There is a profile of Dr. Christiano at the bottom of the post as well for anyone interested in knowing more about her.

Also, I really liked the part of your e-mail about Laser eye surgery. That was a great point to make. I’m really surprised that she actually read a long e-mail such as this, as it is my understanding that many professionals don’t have the time to read long e-mails.I think that shows her dedication to the hairless gene studies. Good job, Eddy. Maybe she will contact you and see if you would like to be involved in clinical trials??

Electrolysis will work for any kind of hair, but your problem is the amount of hair. Having brown skin does not exclude you from laser therapy, but makes the task a little more difficult. Both modalities used together could be helpful to speed of the process. You should be advised to focus on an area of priority. But, as I thought about your situation, I’m concerned about the amount of hair you describe and it appears that a medical consultation is in order.

Laser and electrolysis can help. There are places here in the US that can work on you very fast to remove the hair and others can point them out to you. James Walker the seventh (certified professional electrologist)here on hairtell is very, very good with the speed factor and in the advice area if you want to fly over!

Also, I’m preoccupied with going another level with this and mentioning that you should immerse yourself in the research that is going on in Europe and the United States and perhaps becoming part of a clinical study. There is one clinical study happening now that I will mention in a minute.

A lot of hair research centers focus on hair loss, but through this research, the mystery to solving hypertrichosis (too much hair) could very well be solved at the cellular level, as well. This is the hope of many. Sirna Dermatology (Boulder,Colorado) is involved with researching and developing a way to to deliver “agents” at the cellular level that interfers with the messenger part of the cell, RNA, that will interfer with hair cells duplicating. Dr. Christiano’s research has been acquired by SiRNA for hopefully applying her work in relation to providing permanent hair removal at the cellular level for people like yourself with copious amounts of hair. She is a board member of Sirna Therapeutics. Her profile is listed below.

I am mentioning another level of involvement, the research side of things, because of the amount of hair you describe. I have not seen any clinical studies that are recruiting patients yet, however, The University of Jena (Germany) will be ready to go for a study they are doing for hypertrichosis using photodynamic therapy, but it is still not open for patient recruitment yet. Maybe you could apply and participate at the appropriate time?

I have sent your post to Dr. Christiano as a gesture to remind her how people with copius amounts of hair suffer in their daily lives and how they would honor her and her work forever if she could find a safe and effective way to rid them of too much hair - safely. You will have to snoop around on your own to involve yourself in what hope awaits you for the future.
http://www.clinicaltrials.gov (U.S.) can be a start.

Research Summary
Molecular basis of inherited skin and hair disorders in humans and mice.
Christiano Lab

The major focus of our research is the study of inherited skin and hair disorders in humans and mice, through a classical genetic approach including identification and phenotyping of disease families, genetic linkage, gene discovery and mutation analysis, and functional studies relating these findings to basic questions in epidermal biology. Our interests include transcriptional regulation of hair cycling and differentiation, the biology of cadherin-mediated cell adhesion junctions known as desmosomes, and the morphogenesis epidermal appendages such as hair and teeth. A long-range goal of our research is to develop genetic and cell-based therapies for skin and hair diseases through understanding disease pathogenesis. We are using epithelial reprogramming as a therapeutic approach for inherited skin diseases.

In addition to human congenital alopecia, mutations in this gene also underlie the hairless and rhino phenotypes in mice. Hairless appears to have a multitude of functions, and its relationship to thyroid hormone, transcriptional co-repression and apoptosis, among other cellular events, is currently under investigation.

Current Projects

  1. Epithelial Reprogramming
    We instead asked whether we could identify an ectopic source of epithelial cells that could be induced into becoming a skin stem cell. Rather than searching for markers of the epidermal stem cell itself, we asked whether we could reprogram other epithelia into skin under the appropriate inductive (dermal) influences.

    9/2002-5/2004

  2. Functional Analysis of the Hairless Protein
    We have combined our preliminary studies with several emerging lines of biological data to formulate a hypothesis which asks three questions. First, is hairless a DNA-binding protein, and if yes, what is its signature sequence? Secondly, is hairless a transcriptional coactivator, and if yes, what are its interaction partners? Finally, what are the downstream targets of hairless gene regulation? We anticipate that this approach will allow us to gain novel insights into the function of the hairless protein for the first time.

    9/2001-7/2006

  3. Molecular genetics of the keratodermas
    The project consists of three integrated and interdependent aims. The first one is to search for mutations in eleven candidate genes in a small number of families with a characterized inherited keratoderma. The second is to identify the mutated genes in large pedigrees with well-characterized, dominant, and fully penetrant keartodermas, one with EB superficialis, the other “Novel Acantholytic Disease.” The third is to isolate and characterize genes that play a role in epidermal differentiation.

Hey Eddy,

Nice post. I do hope these companies, namely Merck understand the possible implications such a treatment would have on so many people.

Eddy,

thanks a lot for this great email. I hope Angela sent it to some people with some decision-making power.

I haven’t heard anything from Sirna. Even though they were taken over by Merck, there should be some news on the company itself, but it’s like they have fallen in to a black hole.

hi everybody,

Merck released its updated pipeline today. I haven’t found anything about our magic cream here:

http://a248.e.akamai.net/7/248/430/20070409134202/www.merck.com/finance/pipeline.swf

nor on the clinicaltrials.gov site.

Has anybody an idea what happened with the sirna program?

I think it’s a pretty safe bet Sirna has been buried within Merck, never to be seen again. I hate to say that because I never thought it was happen, but I check their “website” quite often and it’s never been updated.

hi everyone,

  1. there is an update on www.sirna.com but no info on the magic cream. I tried to call them, but this answering procedure is a bit confusing. Maybe someone else can try it.

  2. there is also an update on www.applisonix.com: they developed the protoype, they want to conduct clinical tests in the middle of 2008 and product launch is planed for 2009.

  3. there are also changes on www.photoderma.com
    clinical trials are scheduled for the beginning of 2008 for permanent hair removal

I know this is a really old post, but is there any update on this? I can’t find anything newer than 2009 via google.

Good question…

Merck purchased Sirna in 2006 and I don’t think researching how to get rid of unwanted hair was on their priority list, as it was for Sirna. If anything, they would be pursuing the oncology track, for obvious reasons They understand how to “silence the genes”, but the delivery system is a real challenge. You might want to research the two doctors that discovered how to interfer with the RNA (Craig Mello and Andrew Fire) and see if they are still doing this research: http://www.ip-right.org/Right/rnai

I read an interview with one of the head developers of this. He said the main reason it fell through was due to technological shortcomings. Namely, they couldn’t get the siRNA to penetrate into the skin.

However, researchers from Northwestern have just developed a topical delivery method to do just that!..

I wonder if the people from Sirna will pick up on this new technology and continue with their project!!
