Doctor has high hopes for new hair-loss treatment

HOUSTON (KTRK) -- For people experiencing hair loss, there's a new treatment on the market called stem cell therapy. It's less invasive than hair transplant procedures, and could someday be the gold standard.

The idea that this procedure could spark new hair growth has breathed new life into the race to clone hair. And that may just be the beginning.

Arlene Johnson has been losing hair for years now, and she's hoping to turn back the clock.

"It was taking me like 20, 30 minutes to comb my hair, and with products to make it look like I had more hair, and that is aggravating," Johnson said.

Her weapon of choice? What could be the future of cosmetic treatments: stem cell therapy.

Hair loss specialist Dr. Daniel McGrath is hoping to jumpstart the stem cells in Johnson's hair follicles.

"Typically with female patients they have female pattern hair loss -- thinning they can't do anything about -- and it gives them thickening and regeneration of their hair, that's huge," Dr. McGrath said.

Here's how it works: A small amount of the patient's blood is taken, and the platelet-rich plasma is separated out. Then it's mixed with a wound-healing powder called "a-cell", and injected back into the scalp. Johnson's head has been numbed, so she doesn't feel a thing. Finally, the doctor using some massage and small needles to create tiny wounds, which will help trigger a healing response.

"The results we've seen thus far, not only in my practice but my colleagues I'm close with across the country, has been better than 80 percent re-growth of hair or regeneration of hair across the board with our patients," Dr. McGrath said.

This sort of therapy is being tested for a host of cosmetic uses, from plumping lips, to firming sagging skin -- even breast enhancement.

Gazette.Net: Stem cell biotech Osiris Therapeutics wins overseas

Osiris Therapeutics announced a couple of legal and regulatory victories this week.

The Columbia biotech, which develops stem cell treatments for a variety of conditions, won a challenge to its Australian patent.

The patent, filed in 2009, covers the use of mesenchymal stem cells, including the companys intravenous Prochymal product, to treat inflammatory conditions in the gastrointestinal tract, including Crohns disease and ulcerative colitis.

Under Australian law, the opponents identity was not disclosed, Osiris said in a news release.

Actually, the challenge was filed in November by a patent attorney, Gavin Recchia. But under Australian law, such challenges may be filed by anyone, including those without a commercial interest, Victor Portelli of the Australian patent agency said. However, the client of the filer need not be disclosed, at least initially.

The challenge was withdrawn this month before any supporting evidence was filed.

Last year, Prochymal became the worlds first stem cell drug approved by an internationally recognized regulatory authority. Its also approved to treat acute graft versus host disease, a serious complication of bone marrow transplantation that kills up to 80 percent of children affected, many soon after diagnosis, according to Osiris. Canada and New Zealand have approved it, and its also available in the U.S. and six other nations under an expanded access program.

Osiris also reported the European Medicines Agency has designated it as the orphan drug title holder for Prochymal for treating graft versus host disease. The designation provides incentives, such as market exclusivity for up to 10 years following approval.

Osiris stock rose 9 percent on the news Tuesday, before falling back Wednesday and Thursday.

Cell therapy: New mouse model promises to advance research on induced pluripotent stem cells

Feb. 21, 2013 Cell therapy is a promising alternative to tissue and organ transplantation for diseases that are caused by death or poor functioning of cells. Considering the ethical discussions surrounding human embryonic stem cells, a lot is expected of the so-called 'induced pluripotent stem cells' (iPS cells). However, before this technique can be applied effectively, a lot of research is required into the safety and efficacy of such iPS cells. VIB scientists associated to the UGent have developed a mouse model that can advance this research to the next step.

Lieven Haenebalcke (VIB/UGent): "iPS cells have enormous therapeutic potential, but require more thorough testing before they can be used for such purposes. Using our new mouse model, we can study which mechanisms determine the identity of a cell. This knowledge is essential before we can use cell therapy for regenerative medicine."

Jody Haigh (VIB/UGent): "If we want to give cell therapy a future, then we must continue this type of research and invest in the further development of such technologies. This will result in an improved insight into cellular identity and -- in the long term -- safer options of applying iPS cells or cells derived from iPS cells in clinical studies."

Cell therapy -- replacing cells to provide a cure

Cell therapy is the replacement of lost or poorly functioning cells in patients. For example, such cell therapies could be used to repair the heart muscle after a heart attack, joints affected by arthritis, the pancreas in diabetes or the spine in certain forms of paralysis. This requires cells that are able to multiply in the laboratory and that can be converted to healthy cells of the desired cell type. Human embryonic stem cells meet these criteria, but they are ethically controversial.

iPS cells -- a promising alternative to embryonic stem cells

Shinya Yamanaka recently developed a fairly simple method to reprogram differentiated cells -- such as skin cells -- back to stem cells, so-called "induced pluripotent stem cells" (iPS cells). This earned him the Nobel Prize for Medicine in 2012 (shared with John Gurdon). These iPS cells can be generated using only 4 "reprogramming factors."

As is the case with embryonic stem cells, these iPS cells can be used to produce other cell types, such as heart muscle cells or nerve cells. They can also be cultured indefinitely and there are no ethical objections as they are not obtained from human embryos left over after IVF, but from adult individuals. Furthermore, iPS cells are obtained from the patient and this reduces the risk of rejection during therapeutic applications.

Essential research possible

Before iPS cells can be used effectively and safely as a therapy, it is essential that we gain clear insight into which molecular mechanisms determine the identity of a cell; why and how a cell develops into -- for example -- a heart muscle cell, a nerve cell or a blood cell. In order to do so, Lieven Haenebalcke and Jody Haigh have developed a mouse model that will enable them to conduct this research. They succeeded in creating iPS cells from a variety of mouse cells. Furthermore, the new model allows the investigators to replace the 4 reprogramming factors in these iPS cells efficiently with specific genes in order to create targeted different cell types, such as functional heart muscle cells.

Stem cell 'homing' signal may help treat heart failure patients

Feb. 21, 2013 In the first human study of its kind, researchers activated heart failure patients' stem cells with gene therapy to improve their symptoms, heart function and quality of life, according to a study in the American Heart Association journal Circulation Research.

Researchers delivered a gene that encodes a factor called SDF-1 to activate stem cells like a "homing" signal.

The study is unique because researchers introduced the "homing" factor to draw stem cells to the site of injury and enhance the body's stem cell-based repair process. Generally, researchers extract and expand the number of cells, then deliver them back to the subject.

"We believe stem cells are always trying to repair tissue, but they don't do it well -- not because we lack stem cells but, rather, the signals that regulate our stem cells are impaired," said Marc S. Penn, M.D., Ph.D., Director of Research at Summa Cardiovascular Institute in Akron, Ohio, and lead author and professor of medicine at Northeast Ohio Medical University in Rootstown, Ohio.

SDF-1 is a naturally occurring protein, secreted by cells, that guides the movement of other cells. Previous research by Penn and colleagues has shown SDF-1 activates and recruits the body's stem cells, allowing them to heal damaged tissue. However, the effect may be short-lived. For example, SDF-1 that's naturally expressed after a heart attack lasts only a week.

In the study, researchers attempted to re-establish and extend the time that SDF-1 could stimulate patients' stem cells. Study participants' average age was 66 years.

Researchers injected one of three doses of the SDF-1 gene (5mg, 15mg or 30mg) into the hearts of 17 patients with symptomatic heart failure and monitored them for up to a year. Four months after treatment, they found:

"We found 50 percent of patients receiving the two highest doses still had positive effects one year after treatment with their heart failure classification improving by at least one level," Penn said. "They still had evidence of damage, but they functioned better and were feeling better."

The findings indicate people's stem cells have the potential to induce healing without having to be taken out of the body, Penn said.

"Our study also shows gene therapy has the potential to help people heal their own hearts."

REPEAT: Stem Cell Therapeutics Announces Joint-Venture Agreement With Reneu Inc. and Nexgen Medical Systems, Inc

TORONTO, ONTARIO--(Marketwire - Feb 20, 2013) - Stem Cell Therapeutics Corp. (TSX VENTURE:SSS) ("SCT" or the "Corporation") a life sciences company developing stem cell-related technologies, today announced a joint-venture agreement with ReNeu Inc. of Calgary, AB, Canada, ("ReNeu") and NexGen Medical Systems, Inc. of Melbourne, FL, USA ("NexGen").

ReNeu is a company formed to commercialize drug-based therapies to treat central nervous system disorders in combination with devices and processes for direct-to-brain administration. Subject to the definitive agreement, SCT and NexGen will license their respective technologies to ReNeu under world-wide,royalty-free licenses for the use of NexGen''s FDA-cleared EViTAR line of proprietary intracranial delivery systems and SCT''s NTx-265, -428 and -488 covering the proprietary use of drugs for the regeneration of endogenous neural stem cells.

To the knowledge of the Corporation the EViTAR intracranial delivery system is the only FDA-cleared Class II medical device currently indicated for the injection of material into the brain during intracranial procedures. It is designed for site-specific, low-volume, high-concentration delivery of drugs to target tissues in the brain of patients suffering from stroke, neurodegenerative disease, and tumors. SCT''s NTx-265 is a therapeutic regimen of approved and clinically well-defined drugs that include human Chorionic Gonadotropin ("hCG") and erythropoietin ("EPO") for the regeneration of neural stem cells in patients following stroke, traumatic brain injury and other neurological conditions.

"ReNeu''s perceptive innovation that the combination of SCT''s award-winning, proprietary discoveries by Dr. Sam Weiss, Director of the Hotchkiss Brain Institute, if administered in a direct-to-brain process, holds the promise of delivering the regenerative results that Dr. Weiss'' discovery originally proposed.NexGen''s EViTAR family would appear to be an ideal vehicle for the clinical expansion of the SCT products and we are enthusiastic about its prospects," said David Allan, Executive Chairman of SCT.

Under the Letter of Agreement SCT will own 50% of the joint-venture for which the definitive agreement is anticipated within 60 days, subject to final due-diligence and usual conditions being met.

"The breakthrough benefit to patients that could be expected to result from a positive clinical demonstration from the combination of these two critical elements for the treatment of neurologically degenerative diseases could be of significant importance for the treatment of patients with stroke and other neurological conditions," said Dr. Joseph Tucker, founding CEO of ReNeu. "The most effective preclinical treatments from Dr. Weiss'' work licensed to SCT were the direct-to-brain approaches, which clearly indicated the prospect of important benefit to patients when developed clinically. At the time, SCT proceeded in its clinical development with systemic rather than site-specific administration because of the absence of availability of a direct-to-brain approach, with the consequence that only limited amounts of SCT''s drug combination reached the brain and equivocal clinical outcomes were achieved. We have high expectations that this fortuitous combination of these two novel approaches could have an importantly different and positive outcome."

"NexGen is very excited about this collaboration with SCT and ReNeu," said John Kucharczyk, CEO of NexGen Medical Systems. "The novel treatment methods have the potential to introduce entirely new therapies for several neurological diseases and disorders. NexGen''s proprietary EViTAR neurocatheters are designed for delivery of therapeutic agents directly to target tissues in the brain and spinal cord, which is expected to significantly reduce side-effects associated with systemic delivery of drugs," Kucharczyk added.

ReNeu''s initial board will be composed of David Allan, Executive Chairman of Stem Cell Therapeutics, Dr. John Kucharczyk, CEO of NexGen Medical Systems, Dr. Brad Thompson, Chairman & CEO of Oncolytics Biotech and Dr. Joseph Tucker, founding CEO of ReNeu. The Company intends to vigorously pursue regulatory approval to move the combined technologies into clinical trials with a target of clinical initiation in 2014.

SCT will retain all rights to its endogenous stem cell-stimulating technology other than direct-to-brain administration.
