Samumed — SM04554

October 2014 has perhaps become the most eventful month ever in the hair loss world when it comes to important new developments. Unfortunately, my day job allows me only so much free time, and I am therefore often forced to delay writing posts on new developments by a few days, especially in busy months such as this one.

So that is the excuse behind my delay in writing about Samumed’s SM04554 product and its pending phase 2 US clinical trials.  That clinical trials page was updated several days ago, and the latest development is that these phase 2 trials will run from November 2014 to October 2015.  The company is enrolling 300 male volunteers between the ages of 18 and 55 in this trial, with a number of inclusion and exclusion criteria.  The trial will involve three group (two differing doses, one placebo), and volunteers will be recruited in 14 states spread across the US.  Some of the people supervising these trials are well known in the hair loss world (e.g., Dr. Wilma Bergfeld in Ohio).

What is Samumed’s SM04554?

Samumed is a company that is based in San Diego and is involved in developing small molecule drugs that selectively activate or inhibit Wnt pathways.  I have written a few posts on this blog related to Wnt (see here, here and here).  The whole concept of Wnt signaling pathways is extremely complicated and it is well worth checking out the wiki on it as well as Stanford University’s page on it.  They even have a Linkedin Wnt group where people can ask questions.  Most of the ongoing work regarding Wnt research is related to serious medical problems rather than cosmetic problems.

Samumed’s SM04554 topical solution is thankfully an exception to that rule, and is designed to counter androgenetic alopecia via activating a Wnt pathway.  The company already started initial trials in Australia in 2013 and might even have completed those.  In that Australian trial link, there are a list of contact names underneath and blog readers who are very keen to know more might want to contact some of those people to find out further details.

Funnily enough, earlier this month when I was searching for and updating readers on Histogen’s and Replicel’s presentations at the San Diego Conference of the Mesa, I totally missed that Sanumed was holding an investigative pre-phase 2 clinical trials meeting on its important SM04554 product from October 16-18….also in San Diego of course!

I will be interested to see how this trial works out.  And if successful, will Samumed (like Histogen and Replicel) think about doing further trials in Japan and/or licensing their SM04554 product to a Japanese company in order to speed up time to market?

Excellent new Replicel CEO Interview and Podcast

I may add more to this post about Replicel later this week. For now, check out this excellent new Replicel CEO interview and podcast.

Replicel CEO David Hall Interview

In the interview with James West, Mr. David Hall essentially seems to be claiming that this is a complete cure once the main challenges regarding dosage and frequency are resolved. I now have second thoughts about Histogen’s recent presentation, where they suggest superior results to Replicel.

Regarding their trials, Dr. Hall summarizes that Replicel did a 16 patient Phase 1 study. This is the basis of the data that the company is now using for its Phase 2 study. The same data is also being used by Shiseido in Japan for their pending clinical trials.

In the 16-patient safety trial, Replicel saw an average density growth in 6 months of 11.8%. In comparison, the very best you get with the current drug therapies of Minoxidil (Rogaine) is 16%. And with dihydrotestosterone (DHT) inhibitor Finasteride, about 14%. Moreover, those results are over a lengthier 12-month period of time.

The next step for Replicel is a 160-patient trial that will measure injection frequency and dosage. The reason this could be a complete cure is because they use the hair cells at the back of the head that are completely androgen insensitive. i.e. what is deemed as the permanent donor zone in hair transplants.

You take those permanent hair cells, replicate them, and then inject them into the frontal and crown balding regions of the scalp. In effect, you now have a full scalp of hair that is not susceptible to balding from the ravages of androgens and DHT.
